Hurricane
1 A hurricane（飓风）is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral（螺旋）around a relative calm center know as the“eye”.The“eye” is generally 20 to 30 miles wide,and the storm may ex- tend outward 400 miles. As a hurricane nears land,it can bring heavy rains,high winds,and storms（风暴潮）.The storm surges and heavy rains can lead to flooding.
2 Hurricanes are given a different label,depending on where they occur. If they begin over the North Atlantic Ocean,the Caribbean Sea,the Gulf of Mexico,or the Northeast Pa-cific Ocean,they are called hurricanes.Similar storms that occur in the Northwest Pacific Ocean west of the International Date Line are called typhoon. Near Australia and in the India Ocean, they are referred to as tropical cyclones（龙卷风）.
3 When a hurricane hits land,it can do great damage through its fierce winds,heavy rains , inland（内陆的）flooding, and huge waves crashing onto the shore. During a hurri-cane,homes,businesses,and public buildings may be damaged or destroyed;road and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbour if they do not receive adequate warning.
4 If a hurricane is coming in your area,the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one,stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors,because if the glass breaks it's real-ly dangerous. Do not be fooled if there is a lull（暂停）；it could be the eye of the storm-winds will pick up again.During a hurricane one should stay away from________.
A: inland flooding
B: natural disaster
C: early warning
D: windows and glass doors
E: a constant speed
F: different labels答案：D解析：段首句是典型定义句，该句可能就是该段主题句。该句意为“飓风是一种热带风暴，飓风的持续速度能达到74英里/小时”，显然该定义句在对飓风进行解释，C项“什么是飓风”正好与之呼应，因此答案很可能是C。从该段的主要内容来看，整个段落主要对飓风进行了介绍，内容涉及到风速,飓风刮风的方式，风眼以及飓风所带来的影响，由此可以进一步确认该段的主题是对飓风进行介绍。所以答案为C。
段首句不是定义句，也不是观点句，因此该句成为段落主题句的可能性较小。因为段落开头的句子即使不是主题句也往往起着引题的作用，所以段落开头的句子建议考生仔细阅读。段首句意为“根据发生的地点不同，飓风被贴上了不同的标签”。该段没有明显的段落主题词，因此跳看段落中的句子以较快的速度把握段落大意。段落中出现了这样一些彼此呼应的结构：they are called hurricanes（它们被称为飓风）, are called typhoon（被称为台风）,are referred to as tropical cyclones（被称为龙卷风）。显然这些彼此呼应的结构都与段首出现的“飓风被贴上了不同的标签”，指飓风有不同的名字，这正好与B项“飓风都有哪些不同的名字”呼应，因此答案为B。
段落中两次出现了damage“破坏”一词（提示：在段落中反复出现，但并非贯穿整个段落而出现的词可能是段落主题词，也可能不是），该词还在段首句中出现了，因此首先关注段首句。该句意为“当飓风抵达陆地时，它可能带来狂风，暴雨，内陆洪水和冲上海岸的巨浪而造成很大的破坏”。该句是观点句，因此可能是该段主题句。跳读整个段落，很容易在段落中发现这样的字眼：damage“破坏”, destroy property“破坏财产（即造成财产损失）”,kill people“夺取人们的生命”, fishermen at risk“渔民处于危险之中”，这些词语都与段首句中提出的“飓风造成的破坏”呼应，因此该题答案为D项“飓风会造成什么样的破坏”。提示：在需要通过阅读段落而把握段落大意的情况下，跳读段落是一个快速识别段落大意的有效方法。跳读不是阅读句子，而是关注段落中词语出现的情况，往往段落中彼此呼应的词语也能烘托出段落的主题思想。
段首句是观点句，该句就是段落主题句。该句意为“如果飓风来到你所在的地区，最重要的事情是保持冷静并且立刻找到躲避处”。依据该句意思来看，该句主要在说明当飓风发生的时候应该怎么做。这与A项“飓风发生的时候你应该怎样做？”意义一致，因此答案为A。
题干意为“根据发生地的不同，飓风有……”。与题干相关的句子在解答前面问题时阅读过，相关句Hurricanes are given a different label, depending on where they occur（随着发生地的不同，飓风被贴上了不同的标签）。由此可知F项“不同的标签”是答案。
题干意为“猛烈的飓风可能变成最具破坏性的……”，利用题干中出现的信 息短语powerful hurricane"猛烈的飓风”作为定位线索，同时关注题干中的修饰词most de- structive“最具破坏力的”在短文中出现的情况：When a hurricane hits land, it can do great damage through its fierce winds,heavy rains,inland flooding,and huge waves crashing on to the shore. During a hurricane,homes,businesses,and public buildings may be damaged or destroyed;road and bridges can be washed away. A powerful hurricane can kill more peo-ple and destroy more property than any other natural disaster.Fishermen are at special risk from hurricanes as they may be at sea when a hurticane arrives and not be able to get to a safe harbour if they do not receive adequate warning．相关句（第三段第三句）意为“与其他任何一种自然灾害相比，猛烈的飓风会夺去更多人的生命，会毁掉更多的财产”。由此可知飓风可能会成为最具有破坏力的自然灾害，因此答案为B项“自然灾害”。
题干意为“当飓风到来的时候，渔民如果正在海上而且还没有得到……，那么他们就会处于很危险的境况中”。利用题干中出现的信息词/短语fishermen , great danger, sea作为定位线索，在第三段中找到相关句：When a hurricane hits land, it can do great dam- age through its fierce winds,heavy rains,inland flooding,and huge waves crashing on to the shore. During a hurricane,homes,businesses,and public buildings may be damaged or de- stroyed;road and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster.Fishermen are at special risk（与great danger呼应）from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbour if they do not receive adequate warning. 相关句（该段最后一句）意为 “当飓风到来时，如果渔民没有收到飓风警报，没有能够到达安全的港口，那么他们就可能处于很危险的境况之中”。由此可知C项“提前的警报”是答案。
题干意为“在飓风发生期间，人们应该远离……”。题干中虽然有细节信息词hurricane“飓风”出现，但因为该词是短文主题词，因此不选用该词作为定位线索。这样一来题干中就没有定位线索词了，在这样的情况下，关注题干中的谓语部分核心动词短语stay away from“远离”在短文中的出现情况：If a hurricane is coming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one,stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from（与stay away from意义相近）windows and glass doors, because if the glass breaks it's really dangerous. Do not be fooled if there is a lull（暂停）;it could be the eye of the storm-winds will pick up again．相关句（第四段倒数第二句）提到“裹上毯子，而且确保远离窗户和玻璃门”，由此判断D项“窗户和玻璃门”是答案。 -

Hurricane（咫风）Katrina
A hurricane is a fiercely powertul , rotating（旋转的）form of tropical storm that can be
124 to 1,240 miles in diameter. The term hurricane is derived from Hurican,the name of a
native American storm god.Hurricanes are typical of a calm central region of low pressure
between 12 to 60 miles in diameter,known as the eye.They occur in tropical regions.
Over its lifetime,one of these storms can release as much energy as 10,000 nuclear
bombs.
The seed for hurricane formation is a cluster（聚集）of thunderstorms over warm
tropical waters.Hurricanes can only form and be fed when the sea-surface temperature
exceeds 27℃ and the surrounding atmosphere is calm.These requirements are met
between June and November in the northern part of the world.
Under these conditions, large quantities of water evaporate（蒸发）and condense（冷
凝）into clouds and rain-releasing heat in the process.It is this heat energy,combined with
the rotation of the Earth,that drives a hurricane.
When the warm column of air from the sea surface first begins to rise,it causes an area
of low pressure.This in turn creates wind as air is drawn into the area.This spinning wind
drags up more moist air from the sea surface in a process that strengthens the storm.Cold
air falls back to the ocean surface through the eye and on the outside of the storm.
Initially,when wind speeds reach 23 miles per hour,these mild,wet and grey weather
systems are known as depressions,or low air pressure.Hurricane Katrina formed in this
way over the south-eastern Bahamas on 23 August 2005.Katrina has had a devastating
impact on the Gulf Coast of the US,leaving a disaster zone of 90,000 square miles in its
wake（尾迹）一almost the size of the UK. Thousands have been killed or injured and more
than half a million people have become homeless in a humanitarian（人道主义的）crisis of a
scale not seen in the US since the Great Depression.The cost of the damage may top
$100 billion.The eye of a hurricane refers to its

Water Resources on the Earth
The second most important constituent（构成成分）of the biosphere（生物圈）is liquid water. This can only exist in a very narrow range of temperatures,since water freezes at 0℃and boils a 100℃．Life as we know it would only be possible on the surface of a planet which had temperature: somewhere within this narrow range.
The earth's supply of water probably remains fairly constant in quantity.The total quantity of water is not known very accurately,but it is about enough to cover the surface of the globe to a depth of about two and three-quarter kilometers.Most of it is in the form of the salt water of the oceans一about 97 percent. The rest is fresh.But three-quarters of this is in the form of ice at the poles and or mountains and cannot be used by living systems until melted.Of the remaining fraction,which h somewhat less than one percent of the whole.There is 10—20 times as much stored underground water as there is actually on the surface.There is also a tiny,but extremely important fraction of the water supply which is present as water vapour in the atmosphere.
Water vapour in the atmosphere is the channel through which the whole water circulation（循环） of the biosphere has to pass.Water evaporated（蒸发）from the surface of the oceans,from lakes and rivers and from moist（潮湿的）earth is added to it. From it the water comes out again as rain or snow,falling on either the sea or the land. There is,as might be expected, a more intensive evaporation per unit area over the sea and oceans than over the land,but there is more rainfall over the land than over the oceans and the balance is restored by the run off from the land in the form of rivers.There is more of rainfall________.
A:over the mountains than over the rivers
B:over the rivers than over the mountains
C:over the land than over the oceans
D:over the oceans than over the land答案：C解析：文章第一段的第二句讲到液态水“only exist in a very narrow range of temperatures"，虽然B（我们星球的表面）也有点道理，但是液态水对温度的要求很高，并非地球的所有表面都有液态水存在，所以答案D正确。
第二段第一句提到地球上水的供给“remains fairly constant in quantity"，数量上是恒定的，它就没有增加也不会减少，只不过会以不同的形态出现，所以选择B（保持不变）。
问题是“地球上绝大部分淡水以什么形式出现？”第二段中间提到淡水时，说到“three-quarters of this is in the form of ice at the poles and on mountains"，即3/4的淡水以冰的形式存在于两极和高山中，后面提到剩余部分的淡水存在于地下，但占比少于1%,所以选项A正确。
词义辫析题， fraction有“小部分”的意思，考虑到前面提到地球97％的水以海洋咸水的形式存在，剩下的3％则以冰的形式存在于两极和高山，余下的自然不多，所以选B。
第三段的最后一句说到“there is more rainfall over the land than over the oceans”，陆地的降雨比海洋要多，但没有提到河流和山脉的降雨比较，所以C正确。大气中的水蒸气是整个生物圈的水循环必经的途径。水从海洋的表面、湖泊、河流和潮湿的泥土中蒸发出来并补充到大气中。水以雨或雪的形式再次出现，降落在海洋或陆地上。可以预料到的是，海洋上空每单位面积的水蒸气比在陆地上空更为密集，但是，陆地比海洋有更多的降雨，水在陆地上以河流的形式流出以保持水资源的平衡。 -

第9题：
单选题Since 1960, the fast-growing town of Hotstone, Arizona, has drawn water from the Gray River, which feeds Lake Mudfish. If the town’s water use continues to grow at its present rate, in about 20 years the water level of Lake Mudfish will inevitably decrease to the point that it can no longer support its biologically fragile population of fish. The prediction above is based on which of the following assumptions?AAs the town’s water requirements grow, it will not be able to meet those requirements by drawing on water sources other than the Gray River.
BSince 1960, the lake’s population of fish has become more biologically fragile.
CThe amount of water that the lake loses to evaporation each year will increase over the next two decades.
DThere are multiple sources of water besides the Gray River that feed into Lake Mudfish.
EThe town of Hotstone will be able to reverse its trend of increasing water use if it implements an aggressive water conservation program.

A: What Should You Do During a Hurricane?
B: What Are Different Names of Hurricanes?
C: What Is a Hurricane?
D: What Damages Can a Hurricane Cause?
E: How Do You Know a Hurricane Is Coming?
F: Where Do Hurricanes Usually Happen?答案：D解析：段首句是典型定义句，该句可能就是该段主题句。该句意为“飓风是一种热带风暴，飓风的持续速度能达到74英里/小时”，显然该定义句在对飓风进行解释，C项“什么是飓风”正好与之呼应，因此答案很可能是C。从该段的主要内容来看，整个段落主要对飓风进行了介绍，内容涉及到风速,飓风刮风的方式，风眼以及飓风所带来的影响，由此可以进一步确认该段的主题是对飓风进行介绍。所以答案为C。
段首句不是定义句，也不是观点句，因此该句成为段落主题句的可能性较小。因为段落开头的句子即使不是主题句也往往起着引题的作用，所以段落开头的句子建议考生仔细阅读。段首句意为“根据发生的地点不同，飓风被贴上了不同的标签”。该段没有明显的段落主题词，因此跳看段落中的句子以较快的速度把握段落大意。段落中出现了这样一些彼此呼应的结构：they are called hurricanes（它们被称为飓风）, are called typhoon（被称为台风）,are referred to as tropical cyclones（被称为龙卷风）。显然这些彼此呼应的结构都与段首出现的“飓风被贴上了不同的标签”，指飓风有不同的名字，这正好与B项“飓风都有哪些不同的名字”呼应，因此答案为B。
段落中两次出现了damage“破坏”一词（提示：在段落中反复出现，但并非贯穿整个段落而出现的词可能是段落主题词，也可能不是），该词还在段首句中出现了，因此首先关注段首句。该句意为“当飓风抵达陆地时，它可能带来狂风，暴雨，内陆洪水和冲上海岸的巨浪而造成很大的破坏”。该句是观点句，因此可能是该段主题句。跳读整个段落，很容易在段落中发现这样的字眼：damage“破坏”, destroy property“破坏财产（即造成财产损失）”,kill people“夺取人们的生命”, fishermen at risk“渔民处于危险之中”，这些词语都与段首句中提出的“飓风造成的破坏”呼应，因此该题答案为D项“飓风会造成什么样的破坏”。提示：在需要通过阅读段落而把握段落大意的情况下，跳读段落是一个快速识别段落大意的有效方法。跳读不是阅读句子，而是关注段落中词语出现的情况，往往段落中彼此呼应的词语也能烘托出段落的主题思想。
段首句是观点句，该句就是段落主题句。该句意为“如果飓风来到你所在的地区，最重要的事情是保持冷静并且立刻找到躲避处”。依据该句意思来看，该句主要在说明当飓风发生的时候应该怎么做。这与A项“飓风发生的时候你应该怎样做？”意义一致，因此答案为A。
题干意为“根据发生地的不同，飓风有……”。与题干相关的句子在解答前面问题时阅读过，相关句Hurricanes are given a different label, depending on where they occur（随着发生地的不同，飓风被贴上了不同的标签）。由此可知F项“不同的标签”是答案。

Hurricane（咫风）Katrina
A hurricane is a fiercely powertul , rotating（旋转的）form of tropical storm that can be
124 to 1,240 miles in diameter. The term hurricane is derived from Hurican,the name of a
native American storm god.Hurricanes are typical of a calm central region of low pressure
between 12 to 60 miles in diameter,known as the eye.They occur in tropical regions.
Over its lifetime,one of these storms can release as much energy as 10,000 nuclear
bombs.
The seed for hurricane formation is a cluster（聚集）of thunderstorms over warm
tropical waters.Hurricanes can only form and be fed when the sea-surface temperature
exceeds 27℃ and the surrounding atmosphere is calm.These requirements are met
between June and November in the northern part of the world.
Under these conditions, large quantities of water evaporate（蒸发）and condense（冷
凝）into clouds and rain-releasing heat in the process.It is this heat energy,combined with
the rotation of the Earth,that drives a hurricane.
When the warm column of air from the sea surface first begins to rise,it causes an area
of low pressure.This in turn creates wind as air is drawn into the area.This spinning wind
drags up more moist air from the sea surface in a process that strengthens the storm.Cold
air falls back to the ocean surface through the eye and on the outside of the storm.
Initially,when wind speeds reach 23 miles per hour,these mild,wet and grey weather
systems are known as depressions,or low air pressure.Hurricane Katrina formed in this
way over the south-eastern Bahamas on 23 August 2005.Katrina has had a devastating
impact on the Gulf Coast of the US,leaving a disaster zone of 90,000 square miles in its
wake（尾迹）一almost the size of the UK. Thousands have been killed or injured and more
than half a million people have become homeless in a humanitarian（人道主义的）crisis of a
scale not seen in the US since the Great Depression.The cost of the damage may top
$100 billion.When the warm air from the sea surface begins to rise,it
A:creates an area of low pressure.
B:supplies cold air to the eye of a hurricane.
C:increases the sea-surface temperature.
D:strengthens the rotation of the earth.答案：A解析： -

Hurricane
1 A hurricane（飓风）is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral（螺旋）around a relative calm center know as the“eye”.The“eye” is generally 20 to 30 miles wide,and the storm may ex- tend outward 400 miles. As a hurricane nears land,it can bring heavy rains,high winds,and storms（风暴潮）.The storm surges and heavy rains can lead to flooding.
2 Hurricanes are given a different label,depending on where they occur. If they begin over the North Atlantic Ocean,the Caribbean Sea,the Gulf of Mexico,or the Northeast Pa-cific Ocean,they are called hurricanes.Similar storms that occur in the Northwest Pacific Ocean west of the International Date Line are called typhoon. Near Australia and in the India Ocean, they are referred to as tropical cyclones（龙卷风）.
3 When a hurricane hits land,it can do great damage through its fierce winds,heavy rains , inland（内陆的）flooding, and huge waves crashing onto the shore. During a hurri-cane,homes,businesses,and public buildings may be damaged or destroyed;road and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbour if they do not receive adequate warning.
4 If a hurricane is coming in your area,the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one,stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors,because if the glass breaks it's real-ly dangerous. Do not be fooled if there is a lull（暂停）；it could be the eye of the storm-winds will pick up again.Depending on where the occur,hurricanes have________.
A: inland flooding
B: natural disaster
C: early warning
D: windows and glass doors
E: a constant speed
F: different labels答案：F解析：段首句是典型定义句，该句可能就是该段主题句。该句意为“飓风是一种热带风暴，飓风的持续速度能达到74英里/小时”，显然该定义句在对飓风进行解释，C项“什么是飓风”正好与之呼应，因此答案很可能是C。从该段的主要内容来看，整个段落主要对飓风进行了介绍，内容涉及到风速,飓风刮风的方式，风眼以及飓风所带来的影响，由此可以进一步确认该段的主题是对飓风进行介绍。所以答案为C。
段首句不是定义句，也不是观点句，因此该句成为段落主题句的可能性较小。因为段落开头的句子即使不是主题句也往往起着引题的作用，所以段落开头的句子建议考生仔细阅读。段首句意为“根据发生的地点不同，飓风被贴上了不同的标签”。该段没有明显的段落主题词，因此跳看段落中的句子以较快的速度把握段落大意。段落中出现了这样一些彼此呼应的结构：they are called hurricanes（它们被称为飓风）, are called typhoon（被称为台风）,are referred to as tropical cyclones（被称为龙卷风）。显然这些彼此呼应的结构都与段首出现的“飓风被贴上了不同的标签”，指飓风有不同的名字，这正好与B项“飓风都有哪些不同的名字”呼应，因此答案为B。
段落中两次出现了damage“破坏”一词（提示：在段落中反复出现，但并非贯穿整个段落而出现的词可能是段落主题词，也可能不是），该词还在段首句中出现了，因此首先关注段首句。该句意为“当飓风抵达陆地时，它可能带来狂风，暴雨，内陆洪水和冲上海岸的巨浪而造成很大的破坏”。该句是观点句，因此可能是该段主题句。跳读整个段落，很容易在段落中发现这样的字眼：damage“破坏”, destroy property“破坏财产（即造成财产损失）”,kill people“夺取人们的生命”, fishermen at risk“渔民处于危险之中”，这些词语都与段首句中提出的“飓风造成的破坏”呼应，因此该题答案为D项“飓风会造成什么样的破坏”。提示：在需要通过阅读段落而把握段落大意的情况下，跳读段落是一个快速识别段落大意的有效方法。跳读不是阅读句子，而是关注段落中词语出现的情况，往往段落中彼此呼应的词语也能烘托出段落的主题思想。

A:lower part
B:rotating part
C:calm central part
D:most violent part答案：C解析：文章的第一段第三句描述了咫风的特点，即一个直径为12英里～60英里的、平静的低气压中心地带，这个中心就叫做eye of a hurricane。
第二段的第一、二句描写咫风的形成原因，最后一句中的These requirements即是第一、二句中所述内容包括A、C、D。所以A、C和D都不是正确选项。
由第四段第一句话可知A为正确答案。
选项A function：功能、运行；选项B pressure：压力、压迫；选项C disaster: 灾难、灾祸；选项D effect：影响、效果。根据第五段中，第三句及第四句所描述的卡特里娜咫风所造成的损失可知本题正确选项为D项。
选项A、B、 C的内容均在课文最后一段中被提到。文中“…in a humanitarian crisis of a scale not seen in the U.S.since the great depression.”的大致意思是：如此大规模的人道主义危机是美国自大萧条以来还未经历过的。D项不符合这句话的意思，所以是正确选项。 -
