The Mysteries of Nazca
In the desert of Peru,300 kilometers from Lima,one of the most unusual artworks in the world has
mystified（迷惑）people for decades._________ (46 ) But from high above,these marks are huge images
of birds,fish,seashells,all beautifully carved into the earth.
The Nazca lines are so difficult to see from the ground that they weren't discovered until the 1930s,
when pilots spotted them while flying over the area. In all,there are about 70 different human and animal
figures on the plain,along with 900 triangles,circles,and lines.
Researchers have figured out that the lines are at least 1,500 years old,but their purpose is still a
mystery.__________(47)However,it would probably be very tricky to land a spaceship in the middle of
pictures of dogs and monkeys.
In the 1940s,an American explorer named Paul Kosok suggested that the drawings are a chronicle（记
录）of the movement of the stars and planets._________(48)Later,an astronomer tested his theory with
a computer,but he couldn' t find any relation between the lines and movements in space.
Another explanation is that the lines may have been made for religious reasons.British researcher Tony
Morrison investigated the customs of people in the Andes Mountain and learned that they sometimes pray by
the side of the road.It's possible that in the past,the lines of Nazca were created for a similar purpose.
_________(49)But the local people have never constructed anything this big.
Recently,two other scientists,David Johnson and Steve Mabee,have speculated that lines could have
been related to water. Nazca is one of the driest places in the world and receives only 2cm of rain every year.
While Johnson was searching for ancient water sources in the area,he noticed that some waterways built by
ancient people were connected with the lines.Johnson believes that the Nazca lines are a giant map of the
underground water in the area._________(50)

Water
Earth is like a big blue marble.From high above the Earth and from the moon,the planet gleams and shines.The blue water in the oceans and seas of the Earth makes a dramatic image.The white clouds above the Earth add beauty to the picture.Water is the source of this beauty and the source of life on Earth.It is the reason people can live on this planet. Water is everywhere.(46)_______.It is in the soil,the ground that grows the food.Water is in rock deep under the ground, in natural holding areas一in storage.In a real sense,water keeps Earth alive.
Nature has an unchanging amount of water. Nature has a perfect system for recycling water. (47)_____.It falls as rain.Then it goes to one of three places.It might sink slowly through the soil into the natural holding areas in the rock.(48)_______一by becoming vapor,or gas.It might run off into streams,rivers and oceans.By itself,nature can keep the balance and provide plenty of clean water for us.Nature recycles water.
However,people cause problems for this natural recycling system.Nature's recycling system can work well(49)________.Some ways that people upset nature are easy to understand.For example, dirty sewage（污水沟系统）water from homes and factories must not mix with drinking water. People get sick from drinking contaminated water. Sometimes water from factories goes into streams and rivers.It enters into the groundwater. It can flow into lakes too.This kind of contamination from industry(waste water from factories) can be dangerous for people.If water contains poisons and chemicals,it is poison.(50)________;some poisons kill people as well as birds and animals.Without knowing,people can upset nature's recycling system.
Lakes and rivers add beauty to the world. People enjoy water for entertainment purposes,too. People enjoy swimming and playing in the cool water of a lake in the summer. They like to ride on boats on rivers.Many people enjoy catching fish in the rivers.They fish for food and for sport.However,in some places,the water of the lakes and rivers is no longer safe.These rivers and lakes are contaminated.The fish are dying because of the chemicals from farms and factories.People cannot swim in the polluted water._________（46）
A:Poison makes people sick
B:It is in the air that people breathe
C:We can not live without water
D:Water is used again and again
E:only if people work with the system and not against it
F: It might disappear into the air quickly答案：B解析：文章前一句说水到处都存在，那么后一句应该跟此句有关系，而且下一句说“它存在土壤里”，因此选项B项“它在人们呼吸的空气里”是最合适的。
文章前一句说大自然有一个循环水的完美系统，那么后一句相关的选项只有D项“水可以一遍又一遍地反复利用”。
从本句的前后句看这是一个排比句式，三句话都是以it might开头，而后半句“变成蒸汽或水汽”更证明选项F是最合适的。
本句前一句讲人们会引起大自然循环体系的问题，那么空格里应该填入人们怎么做大自然的循环体系才能很好地运转。因此选项E“只有顺着这个系统，而不是对它造成破坏”是最佳选择。
本句前后句的关键词是“poison"，因此判断只有选项A“毒物使人生病” 最合适。 -

New Foods and the New World
In the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.
According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.According to the passage,which of the following has changed the most in the last 500 years?
A: Food.
B: Chocolate.
C:Potato.
D: Coffee.答案：A解析：细节题。第一段第一句： In the last 500 years , nothing about people—not their clothes,ideas , or languages—has changed as much as what they eat.（在过去的500年中，没有任何关于人类的东西，如他们的衣服，观点或语言，会像他们吃的食物变化那么大）同时使用比较级和否定词表示最高级，意思恰恰就是A选项的内容。
细节题。从第一段最后两句话：London shops where chocolate drinks were served became important meeting places. Some still exist today.（在伦敦，供应巧克力饮料的店铺成为了重要的聚会地点。直到今天还存在一些这样的店铺）可以推断这里的some指的就是London shops。
细节题。第二段第三句：Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “ Potato Famine ” of 1845～1846.（爱尔兰人非常依赖土豆，在1845年到1846年期间的土豆饥荒中成千上万的爱尔兰人由于土豆欠收而挨俄）。强调the crop failed , the crop即potato。 A项没有说明土豆欠收这个关键事实；B项是starve导致的结果，并非原因;C项文章并未提及。
细节题。根据第三段倒数第二句：But it is native（本土的、当地的）to Ethiopia．句中it即指coffee，意思是咖啡最早产自埃塞俄比亚。A、B项和But it is native to Ethiopia矛盾；根据第三段最后一句：Arabs最早将咖啡制作为饮品。可以推断D是错误的。
推断题。第三段最后一句：It ( coffee ) was first made into a drink by Arabs during the 1400's.最后一段讲述这个阿拉伯传说就是为了证明阿位伯人首先发明了咖啡这种饮品，即D选项的内容。 -

The Sea
What do you know about the sea?We know that it looks very pretty when the sun is shining on it.We
also know that it can be very rough when there is a strong wind.What other things do we know about it?The
first thing to remember is that the sea is very big.When you look at the map of the world you will find there
is more water than land.The sea covers three quarters of the world.
The sea is also very deep in some places.It is not deep everywhere.Some parts of the sea are very shal-
low.But in some places the depth of the sea is very great.There is one spot,near Japan,where the sea is
nearly 11 kilometers deep!The highest mountain in the world is about 9 kilometers high.If that mountain
were put into the sea at that place,there would be 2 kilometers of water above it！What a deep place!
If you have swum in the sea,you know that it is salty.You can taste the salt,Rivers,which fi0w into the
sea.carry salt from the land into the sea.Some parts of the sea are saltier than other parts,There i、one sea,
called the Dead Sea,which is very salty.It is so salty that swimmers cannot sink!Fish cannot live in the
Dead Sea!
In most parts of the sea,there are plenty of fishes and plants.Some live near the top of the sca.Othurs
live deep down.There are millions of tiny living things that float in the sea.These floating things are so small
that it is hard to see them.Many fish live by eating them.
The sea can be very cold.Divers,who go deep down in the sea,know this.On the top the water may be
warm.When the diver goes downwards,the sea becomnes colder and colder. Another thing happens.When the
diver goes deeper,the water above presses down on him.It squeezes him.Then the diver has to wear clothes
made of metal.But he cannot go very deep.Some people who wanted to go very deep used a very strong diving
ship!They went down to the deepest part of the sea in it.They went down to a depth of eleven kilometers!The sea is 6 kilometers in depth on average.
A:Right
B:Wrong
C:Not mentioned答案：C解析：第一段说“当阳光普照大海时大海看起来很美丽”，但并没说“风平浪静”时也是如此。
第一段的最后一句话说海洋覆盖了地球四分之三的面积，由此可推知陆地只占地球 25％的面积。

单选题请阅读 Passage 2，完成第 26~30小题。Passage 2 The common cold is the world's most widespread illness， which is plague that flesh receives.The most widespread fallacy of all is that colds caused by cold.They are not， They are caused by viruses passing on from person to person.You catch a cold by coming into contact， directly or indirectly， with someone who already has one.If cold causes colds， it would be reasonable to expect the Eskimos to suffer from them forever.But they do not.And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.During the First World War soldiers who spent long periods in the trenches， cold and wet，showed no increased tendency to catch colds.In the Second World War prisoners at the notorious Auschwitz concentration camp， naked and starving， were astonished to find that they seldom had colds.At the Common Cold Research Unit in England， volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time.After taking hot baths， they put on bathing suits， allowed themselves to be with cold water， and then stood about dripping wet in drafty room.Some wore wet socks all day while others exercised in the rain until close to exhaustion.Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.If， then， cold and wet have nothing to do with catching colds， why are they more frequent in the winter? Despite the most pains-taking research， no one has yet found the answer， One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times， and this makes it easier for cold viruses to be passed on.No one has yet found a cure for the cold.There are drugs and pain suppressors such as aspirin， but all they do is relieve the symptoms.Arctic explorers may catch colds when ____.Athey are working in the isolated arctic regions
Bthey are writing reports in terribly cold weather
Cthey are free from work in the isolated arctic regions
Dthey are coming into touch again with the outside world

单选题请阅读 Passage 2，完成第 26~30小题。Passage 2 The common cold is the world's most widespread illness， which is plague that flesh receives.The most widespread fallacy of all is that colds caused by cold.They are not， They are caused by viruses passing on from person to person.You catch a cold by coming into contact， directly or indirectly， with someone who already has one.If cold causes colds， it would be reasonable to expect the Eskimos to suffer from them forever.But they do not.And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.During the First World War soldiers who spent long periods in the trenches， cold and wet，showed no increased tendency to catch colds.In the Second World War prisoners at the notorious Auschwitz concentration camp， naked and starving， were astonished to find that they seldom had colds.At the Common Cold Research Unit in England， volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time.After taking hot baths， they put on bathing suits， allowed themselves to be with cold water， and then stood about dripping wet in drafty room.Some wore wet socks all day while others exercised in the rain until close to exhaustion.Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.If， then， cold and wet have nothing to do with catching colds， why are they more frequent in the winter? Despite the most pains-taking research， no one has yet found the answer， One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times， and this makes it easier for cold viruses to be passed on.No one has yet found a cure for the cold.There are drugs and pain suppressors such as aspirin， but all they do is relieve the symptoms.The passage mainly discusses ____.Athe experiments on the common cold
Bthe cures about the common cold
Cwhy and how people catch colds
Dthe continued spread of common colds

Mt. Desert Island
The coast of the State of Maine is one of the most irregular in the world.A straight line running from the
southernmost coastal city to the northernmost coastal city would measure about 225 miles.If you followed the
coastline between these points,you would travel more than ten times as far. This irregularity is the result of
what is called a drowned coastline._________(46)At that time,the whole area that is now Maine was part of
a mountain range that towered above the sea. As the glacier（冰川）descended , however , it expended
enormous force on those mountains,and they sank into the sea.
As the mountains sank,ocean water charged over the lowest parts of the remaining land,forming a series
of twisting inlets and lagoons（咸水湖）.The highest parts of the former mountain range,nearest the shore,
remained as islands._________(47)Marine fossils found here were 225 feet above sea level,indicating the
level of the shoreline prior to the glacier.
The 2,500-mile-long rocky coastline of Maine keeps watch over nearly two thousand islands. Many of
these islands are tiny and uninhabited,but many are home to thriving communities.Mt. Desert Island is one
of the largest,most beautiful of the Maine coast islands.Measuring 16 miles by 12 miles.Mt.Desert was
essentially formed as two distinct islands._________(48)
For years,Mt. Desert Island,particularly its major settlement,Bar Harbor,afforded summer homes for the
wealthy.Recently though,Bar Harbor has become a rapidly growing arts community as well.But,the best part
of the island is the unspoiled forest land known as Acadia National Park.Because the island sits on the
boundary line between the temperate（温带）and sub-Arctic zones , the island supports the plants and ani-
mals of both zones as well as beach , inland , and alpine（高山的）plants. _________( 49 ) The establishment
of Acadia National Park in 1916 means that this natural reserve will be perpetually available to all people,not
just the wealthy.Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy
camping,cycling,and boating. Or they may choose to spend time at the archeological museum,learning about
the Stone Age inhabitants of the island.
The best view on Mt.Desert Island is from the top of Cadillac Mountain._________(50)From the sum-
mit,you can gaze back toward the mainland or out over the Atlantic Ocean and contemplate the beauty
created by a retreating glacier._________(49)
A:This mountain rises 1,532 feet,making it the highest mountain on the Atlantic seaboard.
B:It is split almost in half by Somes Sound,a deep and narrow stretch of water,seven miles long.
C:The wealthy residents of Mt.Desert Island selfishly kept it to themselves.
D:Mt. Desert Island is one of the most famous of all the islands left behind by the glacier.
E:The term comes from the activity of the ice age.
F: It also lies in a major bird migration lane and is a resting spot for many birds.答案：F解析：下面提到了“At that time”和冰川融化，可知这一句应该与冰河时期有关，故选E。
由空格的前后提示可知选B。

Water
Earth is like a big blue marble.From high above the Earth and from the moon,the planet gleams and shines.The blue water in the oceans and seas of the Earth makes a dramatic image.The white clouds above the Earth add beauty to the picture.Water is the source of this beauty and the source of life on Earth.It is the reason people can live on this planet. Water is everywhere.(46)_______.It is in the soil,the ground that grows the food.Water is in rock deep under the ground, in natural holding areas一in storage.In a real sense,water keeps Earth alive.
Nature has an unchanging amount of water. Nature has a perfect system for recycling water. (47)_____.It falls as rain.Then it goes to one of three places.It might sink slowly through the soil into the natural holding areas in the rock.(48)_______一by becoming vapor,or gas.It might run off into streams,rivers and oceans.By itself,nature can keep the balance and provide plenty of clean water for us.Nature recycles water.
However,people cause problems for this natural recycling system.Nature's recycling system can work well(49)________.Some ways that people upset nature are easy to understand.For example, dirty sewage（污水沟系统）water from homes and factories must not mix with drinking water. People get sick from drinking contaminated water. Sometimes water from factories goes into streams and rivers.It enters into the groundwater. It can flow into lakes too.This kind of contamination from industry(waste water from factories) can be dangerous for people.If water contains poisons and chemicals,it is poison.(50)________;some poisons kill people as well as birds and animals.Without knowing,people can upset nature's recycling system.
Lakes and rivers add beauty to the world. People enjoy water for entertainment purposes,too. People enjoy swimming and playing in the cool water of a lake in the summer. They like to ride on boats on rivers.Many people enjoy catching fish in the rivers.They fish for food and for sport.However,in some places,the water of the lakes and rivers is no longer safe.These rivers and lakes are contaminated.The fish are dying because of the chemicals from farms and factories.People cannot swim in the polluted water._________（49）
A:Poison makes people sick
B:It is in the air that people breathe
C:We can not live without water
D:Water is used again and again
E:only if people work with the system and not against it
F: It might disappear into the air quickly答案：E解析：文章前一句说水到处都存在，那么后一句应该跟此句有关系，而且下一句说“它存在土壤里”，因此选项B项“它在人们呼吸的空气里”是最合适的。
文章前一句说大自然有一个循环水的完美系统，那么后一句相关的选项只有D项“水可以一遍又一遍地反复利用”。
从本句的前后句看这是一个排比句式，三句话都是以it might开头，而后半句“变成蒸汽或水汽”更证明选项F是最合适的。
本句前一句讲人们会引起大自然循环体系的问题，那么空格里应该填入人们怎么做大自然的循环体系才能很好地运转。因此选项E“只有顺着这个系统，而不是对它造成破坏”是最佳选择。
本句前后句的关键词是“poison"，因此判断只有选项A“毒物使人生病” 最合适。 -

The Mysteries of Nazca
In the desert of Peru,300 kilometers from Lima,one of the most unusual artworks in the world has
mystified（迷惑）people for decades.__________ (46) But from high above, these marks are huge images
of birds,fish,seashells,all beautifully carved into the earth.
The Nazca lines are so difficult to see from the ground that they weren't discovered until the 1930s,
when pilots spotted them while flying over the area. In all,there are about 70 different human and animal
figures on the plain,along with 900 triangles,circles,and lines.
Researchers have figured out that the lines are at least 1 ,500 years old,but their purpose is still a mystery.
____________(47)However,it would probably be very tricky to land a spaceship in the middle of pictures of
dogs and monkeys.
In the 1940s,an American explorer named Paul Kosok suggested that the drawings are a chronicle
（记录）of the movement of the stars and planets.__________(48) Later, an astronomer tested his theory
with a computer,but he couldn't find any relation between the lines and movements in space.
Another explanation is that the lines may have been made for religious reasons.British researcher Tony
Morrison investigated the customs of people in the Andes Mountain and learned that they sometimes pray by
the side of the road.It's possible that in the past,the lines of Nazca were created for a similar purpose.
__________(49)But the local people have never constructed anything this big.
Recently,two other scientists,David Johnson and Steve Mabee,have speculated that lines could have
been related to water. Nazca is one of the driest places in the world and receives only 2cm of rain every
year. While Johnson was searching for ancient water sources in the area,he noticed that some waterways
built by ancient people were connected with the lines.Johnson believes that the Nazca lines are a giant map
of the underground water in the area.________(50)__________（46）
A:Other scientists are now searching for evidence to prove this.
B:A Swiss writer named Erich Von Daniken wrote that the Nazca lines were designed as a landing place for UFOs.
C:Scholars differ in interpreting the purpose of the designs.
D:The largest pictures may have been the sites for special ceremonies.
E:Seen from the ground,it looks like lines scratched into the earth.
F:He called Nazca"the largest astronomy book in the world".答案：E解析：此空下文内容的视角转向了高处，即high above，空格处的视角应该是地面，故选E。
由此空下文的转折词however可知，此空的内容和某种飞行器着陆的情况相关，故选B。
由下文一句的关键词astronomer可知，本段对奇异图案的猜想和天文学相关，故选F。
本段对纳斯卡的神奇图案做出了和宗教相关的解释。这些图案可能是古时的人们祈 祷所用到的，因此这些巨幅图案可能是一些特殊仪式的现场，故选D。
3～6段从不同角度对纳斯卡的神秘图案进行了解释，但相继被后续的反证推翻，本段 只是提出了另外一种假设，因此下文应该提及相关的证据，故选A。 -

New Foods and the New World
In the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.
According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.Coffee originally came from_______.
A:.Brazil
B: Colombia
C:Ethiopia
D: Arabia答案：C解析：细节题。第一段第一句： In the last 500 years , nothing about people—not their clothes,ideas , or languages—has changed as much as what they eat.（在过去的500年中，没有任何关于人类的东西，如他们的衣服，观点或语言，会像他们吃的食物变化那么大）同时使用比较级和否定词表示最高级，意思恰恰就是A选项的内容。
细节题。从第一段最后两句话：London shops where chocolate drinks were served became important meeting places. Some still exist today.（在伦敦，供应巧克力饮料的店铺成为了重要的聚会地点。直到今天还存在一些这样的店铺）可以推断这里的some指的就是London shops。
细节题。第二段第三句：Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “ Potato Famine ” of 1845～1846.（爱尔兰人非常依赖土豆，在1845年到1846年期间的土豆饥荒中成千上万的爱尔兰人由于土豆欠收而挨俄）。强调the crop failed , the crop即potato。 A项没有说明土豆欠收这个关键事实；B项是starve导致的结果，并非原因;C项文章并未提及。
细节题。根据第三段倒数第二句：But it is native（本土的、当地的）to Ethiopia．句中it即指coffee，意思是咖啡最早产自埃塞俄比亚。A、B项和But it is native to Ethiopia矛盾；根据第三段最后一句：Arabs最早将咖啡制作为饮品。可以推断D是错误的。
推断题。第三段最后一句：It ( coffee ) was first made into a drink by Arabs during the 1400's.最后一段讲述这个阿拉伯传说就是为了证明阿位伯人首先发明了咖啡这种饮品，即D选项的内容。 -

The Sea
What do you know about the sea?We know that it looks very pretty when the sun is shining on it.We
also know that it can be very rough when there is a strong wind.What other things do we know about it?The
first thing to remember is that the sea is very big.When you look at the map of the world you will find there
is more water than land.The sea covers three quarters of the world.
The sea is also very deep in some places.It is not deep everywhere.Some parts of the sea are very shal-
low.But in some places the depth of the sea is very great.There is one spot,near Japan,where the sea is
nearly 11 kilometers deep!The highest mountain in the world is about 9 kilometers high.If that mountain
were put into the sea at that place,there would be 2 kilometers of water above it！What a deep place!
If you have swum in the sea,you know that it is salty.You can taste the salt,Rivers,which fi0w into the
sea.carry salt from the land into the sea.Some parts of the sea are saltier than other parts,There i、one sea,
called the Dead Sea,which is very salty.It is so salty that swimmers cannot sink!Fish cannot live in the
Dead Sea!
In most parts of the sea,there are plenty of fishes and plants.Some live near the top of the sca.Othurs
live deep down.There are millions of tiny living things that float in the sea.These floating things are so small
that it is hard to see them.Many fish live by eating them.
The sea can be very cold.Divers,who go deep down in the sea,know this.On the top the water may be
warm.When the diver goes downwards,the sea becomnes colder and colder. Another thing happens.When the
diver goes deeper,the water above presses down on him.It squeezes him.Then the diver has to wear clothes
made of metal.But he cannot go very deep.Some people who wanted to go very deep used a very strong diving
ship!They went down to the deepest part of the sea in it.They went down to a depth of eleven kilometers!The land takes up 25%of the world.
A:Right
B:Wrong
C:Not mentioned答案：A解析：第一段说“当阳光普照大海时大海看起来很美丽”，但并没说“风平浪静”时也是如此。
第一段的最后一句话说海洋覆盖了地球四分之三的面积，由此可推知陆地只占地球 25％的面积。
第二段涉及大海的深度，但并没说到“平均深度”。
第二段说死海咸度大，鱼类不能生存，但并没说所有生物都不能生存。
第四段说在绝大多数海域，有丰富的鱼类和植物，有些生活在海洋表层，有些居住在深 海，因此说越往海洋深处鱼类和植物越少是没有道理的。
由第五段可知潜水员潜得越深，其承受的水压就越大。
