The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
and to move from place to place.In fact,the human body does its work so well that most people don't think
about it very much-until they get sick.
The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
How can you stop these tiny invaders from making you sick?Your skin is the first defense against
germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
body through small cuts in the skin or through the mouth,eyes,and nose.
Once germs are inside your body , your immune（免疫的）system tries to protect you. It looks for and
destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.
That way you will not get the same illness twice.
You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune systerm
strong. You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are
medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.
Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your
antibodies attack it.The heart contains the body's strongest muscle.
A:Right
B:Wrong
C:Not mentioned答案：C解析：由文章第二段的第七句“Viruses are germs that can only live inside animals or plants.”可知，病毒只能生存在动植物体内，故选B。
由第二段内容可知，致病菌有两种：一种是细菌；一种是病毒。病毒会致病，但有一部分细菌是良性的，故选B。
由文章第三段第三句“You can prevent some illnesses simply by washing, with soap andwater.”可知，通过用水打上肥皂清洗皮肤可以预防一些疾病，故选A。
由文章第三段最后一句中“germs can still enter the body through...eyes and nose”可知，致病菌可以通过伤口、口、眼、鼻等进入人体，故选A。
文章并未提及心脏含有人体最强健的肌肉，故选C。
由文章第四段倒数第三句“After a germ is destroyed, the antibodies stay in your body.”可 知，在毁掉致病菌以后，抗体会留在人体中，故选A。

And water helps us go to the bathroom more easily.
Scientists suggest that people take in 1,600 milliliters of water each day.______(48).If you do,your kidneys will have to work much harder to eliminate it. It's better to drink some in morning and some in afternoon.______(49).And during meals,they think water dilutes the juices produced in our stomachs.This can interfere with normal digestion.

Motion Sickness
Living in space looks like lots of fun.You can do certain things in space(like floating
around,or pushing huge objects)that you cannot do on earth.But being in space can do
things to you,too.If you stay too long in a gravity-free environment,your bones could
become weak,and a small spaceship just might annoy you after a while,because space
travel could make you seasick!
On July 4, 1982,after seven days orbiting the earth,astronauts Thomas K. Mattingly
and Henry W. Hartsfield returned home.Although not all of the experiments on board
worked properly,the flight basically seemed to be a success except for one"little"thing:
early in the flight,astronaut Hartsfield became"seasick".
Thomas Mattingly,who is also a jet pilot and is highly resistant to motion sickness on
earth,did much better.Mattingly sailed through space with a steady stomach.But no one
knows why Hartsfield felt uneasy and Mattingly did not.
So far it seems there is no reliable way to predict who will become motion sick in
outer space and who will not.In all,at least four astronauts have suffered from space
motion sickness. Russian and American scientists are working together to try to
understand and solve the motion sickness.Space program officials worry that if so
many highly-trained pilots get sick in space,what will happen when civilians start flying
in the shuttle?
Motion sickness is a disagreeable feeling that comes from the pitching,rolling,
swaying,or just the moving of the object you are riding in or on.Symptoms of motion
sickness include:dizziness,headache,a sinking feeling in the stomach,and vomiting
（呕吐）.
Why does motion make some people ill?
Doctors believe that motion sickness is caused by a disturbance in the inner ear.Our
ears do more than give us hearing.A part of the ears gives us a sense of balance and helps
make us aware of whether we are right side up or upside down.
If you know that you get carsick or seasick,what can you do?
Speak to your doctor. There are certain medicines available that can help stop that
uneasy feeling.But many of them can also make you sleepy.Usually they work best taken
before you begin feeling ill.
Some people also recommend water,ice cubes,mints,or plain toast.But these
remedies do not always work for everyone.
Perhaps,since motion sickness is such a big problem in outer space,researchers
may soon find a way to cure the astronauts一and those of us who stay on earth.The motion sickness some astronauts suffered from during space travel had been caused by the defective digestive system.

Food Poisoning
Food sometimes gets poisoned with harmful things,A person who eats such food can get an illness called
food poisoning. Food poisoning is usually not serious,but some types are deadly.The symptoms of food poi-
soning usually begin within hours of eating the poisoned food.Fever is one of the most common symptoms.
Certain microorganisms（微生物）cause most types of food poisoning. Bacteria and other microorganisms
can poison eggs,meat,vegetables,and many other foods.After entering the body,these tiny living things re-
lease（释放）poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown,pro-
cessed,or prepared.For example,many farmers spray chemicals on crops to kill weeds and insects.Some
people may have a bad reaction to those chemical、when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people.These includo certain kinds
of seafood,grains,nuts,seeds,beans,and mushrooms.
When people handle food properly,the risk of food poisoning is very small.Microorganisms multiply rapidly
in dirty places and in warm temperatures.This means that people should never touch food with dirty hands or
put food on unwashed surfaces.Food should be kept in a refrigerator to stop microorganisms from growing,
Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered
with chemicals before eating it.Finally,people should not eat wild mushrooms or other foods that grow in the
wild.Some of these foods may contain natural materials that are poisonous to humans.In addition,some types
of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If people
eat natural poisons,they must go to the hospital right away to have their stomachs emptied.From Paragraph 5,we can learn that_______________.
A:mushrooms should not he eaten
B:vegetables are safer than meat and seafood
C:natural poisons are more dangerous than chemicals
D:different types of food should he handled differently答案：D解析：该题目考查关于食物中毒的描述。通读全文，可知第一段对食物中毒做了一个简单的 介绍。由第一段第三句“食物中毒通常并不严重，但有些也是致命的”可知D选项表述与原文 一致，B选项“食物中毒就意味着死亡”太绝对，与原文表述不符。从该段第四、五句可知食物 中毒会有很多的症状，最常见的是发烧，由此可知A选项表述正确。从第二段第一句可知食物 中毒也有很多种类，因此C选项表述与原文一致。据此分析，表述错误的只有B选项，因此为正确答案。

Alcoholism
1 .Yes,alcoholism can be treated. Alcoholism treatment programs use both counseling and medication（药物治疗）to help a person stop drinking. Most alcoholics need help to recover from their disease. With support and treatment,many people are able to stop drinking and rebuild their lives.
2. A range of medication is used to treat alcoholism. Benzodiazepines（苯二氮平类药物） are sometimes used during the first days after a person stops drinking to help him or her safely withdraw from alcohol. However,these medications are not used beyond the first few days because they may be highly addictive. Other medications help people remain sober（清醒）. One medication used for this purpose is naltrexone（环丙甲经二经吗啡酮) . When combined with counseling,naltrexone can reduce the strong desire for alcohol and help prevent a person from returning to heavy drinking. Another medication, disulfiram（戒酒硫）,discourages drinking by making the person feel sick if he or she drinks alcohol. Though several medications help treat alcoholism,there is no“magic bullet”.Developing new and more effective medications to treat alcoholism remains a high priority for researchers.
3 .Alcoholism treatment works for many people. But just like any chronic disease,there are different levels of success in treatment.Some people stop drinking and remain sober. Others cannot stop drinking for any length of time. With treatment,one thing is clear,however,the longer a person stops drinking alcohol,the more likely he or she will be able to stay sober.
4 .No,alcoholism cannot be cured at this time. Even if an alcoholic hasn't been drinking for a long time,he or she can still return to the drinking habit.To guard against it,an alcoholic must continue to avoid all alcoholic drinks.Medication can help some people______.
A: stay confused
B: alcoholic drinks
C: medical treatment
D: feel sick
E: in every person
F: stop drinking答案：F解析：第一段的第一句为主旨句：“酗酒可以被治疗了。”以此判断F项Can Alco-holism Be Treated? (酗酒可以被治疗吗？）正确。要注意的是，C项中的cure是治愈的意思，第一段还没有提及治疗效果，所以此题不能选C。
第二段的第一句为主旨句：“治疗酗酒的用药范围很广泛。”由此可见此段主要在说medication（药物治疗），所以What Medications Treat Alcoholism？ 正确。故选A。
第三段的第一句：“酗酒治疗对很多人管用。”这与D项是相呼应的，D项 Does Alcoholism Treatment Work?（酗酒治疗管用吗？）很适合来概括此段。故选D。
第三段的第一句为主旨句：“不，现在还不能完全治愈酗酒。”这就讲到治疗效果了，所以要选C项。
题干意为“药物治疗可以帮助一些人……。”从文章的题目和上面四个小题我们可以看出，全文在讲酗酒治疗的话题，所以本题很明显要选F，药物治疗可以帮助一些人戒酒。
题干意为“戒酒硫可以通过使嗜酒者……来不喝酒。”disulfiram是关键字，文中第二段倒数第三句“Another medication, disulfiram（戒酒硫）,discourages drinking by making the person feel sick if he or she drinks alcohol.”给出了本题的答案，feel sick。故选D。
题干意为“酗酒治疗，没有一种药可以保证……。”第二段最后两句“Though several medications help treat alcoholism, there is no ‘magic bullet'... ”, magic bullet是俚语，为灵丹妙药的意思。这说明没有一种药可以对个人酗酒药到病除，而科学家们还需开发更有效的新药。所以此题选E。
题干意为“治愈酗酒的关键是避免……。”文章最后一句给出了治疗酗酒的关键:“To guard against it, an alcoholic must continue to avoid all alcoholic drinks.”不再接触酒精饮料是戒酒的关键。所以此题选B。 -

The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
and to move from place to place.In fact,the human body does its work so well that most people don't think
about it very much-until they get sick.
The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
How can you stop these tiny invaders from making you sick?Your skin is the first defense against
germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
body through small cuts in the skin or through the mouth,eyes,and nose.
Once germs are inside your body , your immune（免疫的）system tries to protect you. It looks for and
destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.

Tiny Invaders
The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
and to move from place to place.In fact,the human body does its work so well that most people don't think
about it very much-until they get sick.
The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
How can you stop these tiny invaders from making you sick?Your skin is the first defense against
germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
body through small cuts in the skin or through the mouth,eyes,and nose.
Once germs are inside your body , your immune（免疫的）system tries to protect you. It looks for and
destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.
That way you will not get the same illness twice.

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。 -

Motion Sickness
Living in space looks like lots of fun.You can do certain things in space(like floating
around,or pushing huge objects)that you cannot do on earth.But being in space can do
things to you,too.If you stay too long in a gravity-free environment,your bones could
become weak,and a small spaceship just might annoy you after a while,because space
travel could make you seasick!
On July 4, 1982,after seven days orbiting the earth,astronauts Thomas K. Mattingly
and Henry W. Hartsfield returned home.Although not all of the experiments on board
worked properly,the flight basically seemed to be a success except for one"little"thing:
early in the flight,astronaut Hartsfield became"seasick".
Thomas Mattingly,who is also a jet pilot and is highly resistant to motion sickness on
earth,did much better.Mattingly sailed through space with a steady stomach.But no one
knows why Hartsfield felt uneasy and Mattingly did not.
So far it seems there is no reliable way to predict who will become motion sick in
outer space and who will not.In all,at least four astronauts have suffered from space
motion sickness. Russian and American scientists are working together to try to
understand and solve the motion sickness.Space program officials worry that if so
many highly-trained pilots get sick in space,what will happen when civilians start flying
in the shuttle?
Motion sickness is a disagreeable feeling that comes from the pitching,rolling,
swaying,or just the moving of the object you are riding in or on.Symptoms of motion
sickness include:dizziness,headache,a sinking feeling in the stomach,and vomiting
（呕吐）.
Why does motion make some people ill?
Doctors believe that motion sickness is caused by a disturbance in the inner ear.Our
ears do more than give us hearing.A part of the ears gives us a sense of balance and helps
make us aware of whether we are right side up or upside down.
If you know that you get carsick or seasick,what can you do?
Speak to your doctor. There are certain medicines available that can help stop that
uneasy feeling.But many of them can also make you sleepy.Usually they work best taken
before you begin feeling ill.
Some people also recommend water,ice cubes,mints,or plain toast.But these
remedies do not always work for everyone.
Perhaps,since motion sickness is such a big problem in outer space,researchers
may soon find a way to cure the astronauts一and those of us who stay on earth.People suffering from motion sickness during space travel can alleviate its symptoms by eating or drinking something.

第一篇
Food Poisoning
Food sometimes gets poisoned with harmful things,A person who eats such food can get an illness called
food poisoning. Food poisoning is usually not serious,but some types are deadly.The symptoms of food poi-
soning usually begin within hours of eating the poisoned food.Fever is one of the most common symptoms.
Certain microorganisms（微生物）cause most types of food poisoning. Bacteria and other microorganisms
can poison eggs,meat,vegetables,and many other foods.After entering the body,these tiny living things re-
lease（释放）poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown,pro-
cessed,or prepared.For example,many farmers spray chemicals on crops to kill weeds and insects.Some
people may have a bad reaction to those chemical、when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people.These includo certain kinds
of seafood,grains,nuts,seeds,beans,and mushrooms.
When people handle food properly,the risk of food poisoning is very small.Microorganisms multiply rapidly
in dirty places and in warm temperatures.This means that people should never touch food with dirty hands or
put food on unwashed surfaces.Food should be kept in a refrigerator to stop microorganisms from growing,
Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered
with chemicals before eating it.Finally,people should not eat wild mushrooms or other foods that grow in the
wild.Some of these foods may contain natural materials that are poisonous to humans.In addition,some types
of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If people
eat natural poisons,they must go to the hospital right away to have their stomachs emptied.

问答题◆Topic 6: Is International Tourism an Effective Bridge of Different Nations? Questions for Reference: 1. Why do you think people like to take an international tourism? 2. What kind of situation are the travelers most likely to be faced with when they get on an international tourism? 3. The international tourism does not promote understanding between people from different cultures. Do you agree?正确答案： 【参考答案】
Every year, hundreds of millions of people move around to see a different part of the world. It is natural to assume that tourists who have seen other countries have a better knowledge of the people. That assumption also leads to the conclusion that international tourism promotes understanding between nations. How true is this? Let us examine what tourists do in a different country.
First, before going abroad, tourists are often told by their travel agents of the possible hazards which sometimes include local people. They are given example of extreme cases where victims are always the travelers. Then, when they arrive, they are immediately taken to their hotels in big coaches. They flood places where local people don’t go. Their shopping, meals, entertainment all take place in secluded areas. They wear a bubble all the way. Apart from speaking to the guide and a few shop assistants, tourists rarely talk to the local people. To make it even worse, they meet pickpockets; they are ripped off by dishonest traders.
Furthermore, very few local people bother to talk to them out of a genuine interest in the guests’ country, people and culture. Therefore, when asked how much they know about the local people, their answer is “very little”.
If someone really wants to understand a different culture, he has to learn its language, stay there for at least a few month without wearing a bubble, learn how to curse and swear, bargain with a vegetable vendor and then he can say that he understands the people.解析： 暂无解析
