No one can change the weather．Nobody can control the weather．But if we read correctly the 36 around us we can 37 what the more changes in the weather will be like the following day，which is 38 weather forecasting．
For many centuries and in all countries people have 39 the weather and tried to make weather forecasting．Sometimes distant objects 40 hills and tall trees seem to be very clear 41 near．This is a sign of much water-vapour (水蒸气) in the 42 and therefore a rain will probably come．Rings round the sun are a sign of coming 43 ．Many people feel in their 44 the coming of wet weather．Their joints (关节) ache．Some birds fly 45 if fine weather is coming but they fly very near the ground if 46 or stormy weather is 47 the way．It is probably because of the insects (昆虫) which they are hunting 48 they my 49 ．
If you see a rainbow during rainy weather，this is a sign 50 the weather will become clear and fine．Such 51 always come in the evening．If the stars twinkle clearly at night，then fine weather will 52 ．If a fog appears in the morning just about sunrise，then the day will be warm．Instead， 53 a fog appears in the evening，the next day will bring wet weather．If the sunset is misty red in 54 ，then the following day will be fine．If a rainbow appears in the morning，rainy weather will probably come．
Most of the 55 sayings have been made by the people who have used their eyes and brains to make weather forecasting．

第三部分 阅读理解
（共20小题；每小题2分，满分40分）
阅读下列短文，从每题所给的四个选项中，选出最佳选项。
A
Tuvalu，a tiny country in the Pacific Ocean，has asked for help as it fears it will be swallowed up by the sea．
Storms and huge waves are constant threats and none of Tuvalu’s nine little islands is more than five meters above sea level，salt water is already entering the country’s drinking water supply，as well as damaging plants that produce fruit and vegetables．Without urgent help，the country’s days are numbered．
But Tuvalu is not the first place to face sinking into the sea．Venice，a historic city in Italy，best known for its canals，has sunk about 24cm，over the past 100 years．Experts say that it will have sunk another 20cm～50cm by 2050．A century ago，St．Mark’s Square，the lowest point in the city，flooded about nine times a year，nowadays，it happens more than 100 times．While Venice is slowly sinking into the mud on which it stands，Tuvalu’s rising sea level is going up．
The average global temperature has increased by almost 0.5 centigrade degrees over the past century；scientists expect it to rise by extra 1～3 degrees over the next 100 years．
Warmer weather makes glaciers (冰川) melt，adding more water to the ocean．The warmer temperatures also make water expand，so it takes up more space，causing the sea level to rise．The sea level has risen about 10 cm～25 cm in the last 100 year．
The main cause of global warming is human pollution．Through burning coal，oil and gas，people have been increasing the greenhouse gases in the atmosphere，such as CO2．This adds to the power of the greenhouse effect，making the planet even warmer．
Many scientists believe that，if the warming is not stopped，there will be huge climate changes．The sea level could rise by one meter this century．
Should this come true，the sea will swallow up millions of homes and the world will be flooded with“climate refugees”．Man will have to look for somewhere to live．
56．We can infer from the second paragraph that __________．
A．Tuvalu is in danger of being swallowed up by the sea
B．all Tuvalu’s islands are about five meters above the sea level
C．drinking water in Tuvalu has been destroyed
D．Tuvalu is often flooded by storms and waves
57．The author uses Tuvalu and Venice as examples in order to explain __________．
A．they are the first places sinking into the sea
B．they are both sinking into the mud where they stand
C．they will disappear in the future
D．their trouble is caused by global warming
58．What does“climate refugees”mean
A．People who are forced away from their homeland by climate．
B．Climate changes．
C．Rare animals．
D．Climate effect．
59．Which of the following is NOT true according to the passage
A．Tuvalu’s nine little islands are less than five meters above the sea level．
B．The average global temperature has risen by 1～3 centigrade degrees over the past 100 years．
C．The warmer temperature causes the sea level to rise．
D．There will be huge climate changes unless the warming is stopped．
B
Disposing (处理) of waste has been a problem since humans started producing it．As more and more people choose to live close together in cities，the waste disposal problem becomes increasingly difficult．
During the eighteenth century，it was usual for several neighboring towns to get together to select a faraway spot as a dump site．Residents or trash haulers (垃圾拖运者) would transport household rubbish，rotted wood，and old possessions to the site．Periodically some of the trash was burned and the rest was buried．The unpleasant sights and smells caused no problem because nobody lived close by．
Factories，mills，and other industrial sites also had waste to be disposed of．Those located on rivers often just dumped the unwanted remains into the water．Others built huge burners with chimneys to deal with the problem．
Several facts make these choices unacceptable to modern society．The first problem is space．Dumps，which are now called landfills，are most needed in heavily populated areas．Such areas rarely have empty land suitable for this purpose．Property is either too expensive or too close to residential neighborhoods．Long-distance trash hauling has been a common practice but once farm areas are refusing to accept rubbish from elsewhere，cheap land within trucking distance of major city areas is almost nonexistent．
Awareness of pollution dangers has resulted in more strict rules of waste disposal．Pollution of rivers，ground water，land and air is a price people can no longer pay to get rid of waste．The amount of waste，however，continues to grow．
Recycling efforts have become commonplace，and many towns require their people to take part．Even the most efficient recycling programs，however，can hope to deal with only about 50 percent of a city’s reusable waste．
60．The most suitable title for this passage would be __________．
A．Places for Disposing Waste B．Waste Pollution Dangers
C．Ways of Getting Rid of Waste D．Waste Disposal Problem
61．During the 18th century，people disposed their waste in many ways EXCEPT for __________．
A．burying it B．recycling it C．burning it D．throwing it into rivers
62．What can be inferred from the fourth paragraph
A．Farm areas accept waste from the city in modern society．
B．There is cheap land to bury waste in modern society．
C．It is difficult to find space to bury waste in modern society．
D．Ways to deal with waste in modern society stay the same．
63．The main purpose of writing this article is to __________．
A．draw people’s attention to waste management
B．warn people of the pollution dangers we are facing
C．call on people to take part in recycling programs
D．tell people a better way to get rid of the waste
C
The word conservation has a“thrifty (节俭)”meaning．To conserve is to save and protect，to leave what we ourselves enjoy in such good condition that others may also share the enjoyment．Our forefathers had no idea that human population would increase faster than the supplies of raw materials；most of them，even until very recently，had the foolish idea that the treasures were“limitless”and“inexhaustible”．Most of the citizens of earlier generations knew little or nothing about the complicated，and delicate system that runs all through nature，and which means that，as in a living body，an unhealthy condition of one part will sooner or later be harmful to all the others．
Fifty years ago nature study was not part of the school work：scientific forestry was a new idea；timber was still cheap because it could be brought in any quantity from distant woodlands：soil destruction and river floods were not national problems；nobody had yet studied long-term climatic cycles in relation to proper land use；the word“conservation”had nothing of the meaning that it has for us today．
For the sake of ourselves and those who will come after us，we must now set about repairing the mistakes of our forefathers．Conservation should，therefore，be made a part of everyone’s daily life．To know about the table in the ground is just as important to us as a knowledge of the basic arithmetic formulas．We need to know why all watersheds need the protection of plant life and why the running current of streams and rivers must be made to benefit the soil fully before they finally escape to the sea．We need to be caught the duty of planting trees as well as of cutting them．We need to know the importance of big，mature trees，because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic volume above the earth．In brief，it should be our goal to restore as much of the original beauty of nature as we can．
64．The author’s attitude towards the present situation in the use of natural resources is __________．
A．positive B．neutral C．suspicious D．critical
65．According to the author，the greatest mistake of our forefathers was that __________．
A．they had no idea about scientific forestry
B．they had little or no sense of environmental protection
C．they did not know the importance of nature study
D．they had no idea of how to make good use of raw materials
66．With a view to correcting the mistakes of our forefathers，the author suggests that __________．
A．we plant more trees
B．we be taught environmental science，as well as the science of plants
C．environmental education be directed toward everyone
D．we return to nature
67．What does the author imply by saying“living space is figured also in cubic volume above the earth”(Paragraph 3)
A．Our living space on the earth is getting smaller and smaller in volume．
B．Our living space should be measured in cubic volume．
C．We need to take some measures to protect space in volume．
D．We must create better living conditions for both birds and animals．
D
You might think that“global warming”means nothing more than a rise in the world’s temperature．But，rising sea levels caused by it have resulted in the first evacuation (撤离) of an island nation—the citizens of Tuvalu will have to leave their homeland．
During the 20th century，sea level rose 8～12 inches．As a result，Tuvalu has experienced lowland flooding of salt water which has polluted the country’s drinking water．
Paani Laupepa，a Tuvaluan government official，reposed to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years，Many scientists connect higher surface water temperature resulting from global warming to greater and more damaging storms．
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol，an international agreement calling for industrialized nations to reduce their greenhouse gas emissions (导致温室效应的气体排放)，which are a main cause of global warming．“By refusing to sign the agreement the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years，”Laupepa told the BBC．
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries．
Tuvalu is not the only country that is vulnerable (易受影响的) to rising sea levels．Maumoon Gayoon，president of the Maldives told the United Nations that global warming has made his country of 311 000 an“endangered nation”．
68．The text is mainly about __________．
A．bad effects of global warming B．moving of a country to a new place
C．reasons for lowland flooding D．rapid changes in earth’s temperature
69．According to scientists，the DIRECT cause of more and fiercer storms is __________．
A．higher surface water temperature of the sea．
B．continuous global warming
C．rising sea levels
D．greenhouse gas emissions in industralized nations．
70．Laupepa was not satisfied with the United States because it did not __________．
A．sign an agreement with Tuvalu
B．allow Tuvaluans to move to the US
C．believe the problems facing Tuvalu were real
D．agree to reduce its greenhouse gas emissions
71．The country whose situation is similar to that of Tuvalu is __________．
A．New Zealand B．the Maldives
C．the United States D．Australia
E
Where do pesticides (杀虫剂) fit into the picture of environmental disease We have seen that they now pollute soil，water and food，that they have the power to make our streams fishless and our gardens and woodlands silent and birdless．Man，however much he may like to pretend the contrary，is part of nature．Can he escape a pollution that is now so thoroughly distributed throughout our world
We know that even single exposure to these chemicals，if the amount is large enough，can cause extremely severe poisoning．But this is not the major problem．The sudden illness or death of farmers，farm workers，and others exposed to sufficient quantities of pesticides are very sad and should not occur．For the population as a whole，we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world．
Responsible public health officials have pointed out that the biological effects of chemicals are cumulative over long periods of time，and that the danger to the individual may depend on the sum of the exposure received throughout his lifetime．For these very reasons the danger is easily ignored．It is human nature to shake off what may seem to us a threat of future disaster．“Men are naturally most impressed by diseases which have obvious signs，”says a wise physician，Dr Rene Dubos，“yet some of their worst enemies slowly approach them unnoticed．”
72．Which of the following is closest in meaning of the sentence“Man，…is part of nature”(Lines 5～6，Paragraph 1)
A．Man acts as if he does not belong to nature．
B．A man appears indifferent to what happens in nature．
C．Man can avoid the effects of environmental pollution．
D．Man can escape his responsibilities for environmental protection．
73．What is the author’s attitude towards the environmental effects of pesticides
A．Pessimistic． B．Indifferent． C．Defensive． D．Concerned．
74．In the author’s view，the sudden death caused by exposure to large amounts of pesticides __________．
A．is unavoidable because people can’t do without pesticides in farming
B．now occurs most frequently among all accidental deaths
C．has sharply increased so as to become the center of public attention
D．is not the worst of the negative consequences resulting from the use of pesticides
75．People tend to ignore the delayed effects of exposure to chemicals because __________．
A．the danger does not become apparent immediately
B．the present is more important for them than the future
C．limited exposure to them does little harm to people’s health
D．humans are capable of withstanding small amounts of poisoning

How does television affect our lives It can be helpful to those who carefully choose the programs that they watch and harmful to those who watch it too much．
In China，many people worry that children and young people are watching too much television．A survey of 300 youngsters in Shanghai last year showed that，on average，they spent haft of their free time watching television．And two-thirds of them spent
about two and a half hours reading romance and detective stories．Another survey of school-aged children in Wuhan found that half of them said they read very little．
During the Barcelona Olympic Games，tens of millions of Chinese viewers stayed up late to watch the opening ceremonies and other programs．
And television is quickly taking the place of printed material as the major source of news for most Chinese．A recent survey in Beijing found that 63 percent of those surveyed got their news from television through CCTV and local TV stations．

第二节 完形填空
36．A 由if we read correctly the…around可知，根据周围的迹象(signs)识别天气变化，故选A。

38．D 根据句意“这种告诉接下来一天的天气的方法叫做天气预报”可知此题答案为D。
39．A 本题考查动词词义辨析。study“(研究)天气”，最符合句意。learn意为“学习”，search意为“寻找”，guess意为“猜测”，均不符合句意。

47．D on the way意为“在途中”，为固定搭配，句意为“如果大雨或风暴将要到来时，小鸟就会飞得很低”。
48．A 此句是强调句结构。被强调的部分是because of the insect (昆虫) which they are hunting，用that。
49．B 上面的fly near the ground提示可知。小鸟飞得低可能是因为要捕食的昆虫飞得很低的缘故。

62．D 18世纪所使用的垃圾处理疗法是烧、埋、倾倒进河里。第4段论述了这些方法在现代社会的不可接受性。文中历数了刚这些方法处理垃圾的问题，可见在方法上没有进展。
63．A 文章在前三段介绍过去与现在的垃圾处理方法，第4段论述了这些方法在现代社会的不可接受性。后面是人们对这一问题的认识。最后一段强调利用回收的方法依然不能改变目前的严峻形势。文章旨在引起人们对废物管理的进一步关注。

74．D 第2段的开头两句We know that even single exposure to these chemicals，if the amount is large enough，can cause extremely severe poisoning．But this is not the major problem．可知杀虫剂带来人的死亡问题并不是最严重的，故选D。

第四部分 写作
第一节 短文改错
76．take→took 此处应用过去时，与全文时态保持一致。
77．His→My 根据上下文此处啦指自身情况。
78．删去of a lot在此做副词，修饰形容词比较级better。a lot of后接名词。
79．在lost后加上it 此定语从句中的动词lost为及物动词。表示“丢失”，it指代“课本”，故不能省。
80．第一个class→classes 此处class为可数名词，two classes意为“两节课”。
81．later改为late half an hour late意为“迟到半小时”，half an hour later意为“半小时以后”。
82．删去am used to do表示“过去常常做(禁事)”。
83．heard→hear hear和see为并列动词。

A Letter of Appeal
To everyone on our planet，
Over the past years，floods，droughts，landslides，and duststorms have frequently struck our planet—the only habitat of human beings．We can’t forget the tsunami (海啸) that swept Southeast Asia，which caused enormous damage．All these have sounded an alarm to human beings．
Man has damaged the environment almost to the extent of ruining his own living space：lf we pay no attention to the present destructive human activities，our planet will become a tomb instead of a comfortable home．What’s more，we should realize only from our planet can we obtain our shelter，food，clothing and so on．
If we want to continue to live in this world，we had better try the best to protect our natural environment．Effective measures must be taken to stop the destruction caused by human beings．Most importantly，laws must be established to punish those who are involved in destructive conducts．
Sincerely yours，
Li Hua
