B
Particles from car exhausts generate more persistent clouds but less rain, new research suggests. Furthermore, putting more of these particles into the atmosphere reduces the low-level winds, which could reduce the amount of wind power available in very polluted regions. The dry but populated regions may therefore suffer a triple blow as a result of vehicle pollution:less water, less hydropower and less wind energy.
Scientists studied the effects of aerosol(浮质)pollution from cars and industry. They correlated satellite data on wind speeds and the amount of aerosol particles in the atmosphere above the South Coast Basin in California and above China. Results showed that higher concentrations of aerosols were closely associated with slower ground winds. Scientists then used computer models to support the idea that there was a cause and effect relationship behind this correlation.
Particles floating in the atmosphere block energy from the Sun, preventing it from warming the surface of the Earth. Cooler surface temperatures during the day means the low—level and slow moving air does not rise up and mix with the faster winds at higher altitudes. Slower winds also induce less evaporation from oceans, rivers and lakes. And finally, once clouds have formed, they store less moisture in the form of rain. This is because raindrops form around small particles— dust, for instance, or pollution. With more particles in the atmosphere, it takes longer for enough water to condense(凝结)onto a particle to form a raindrop. And if the cloud of fine droplets(小滴)moves to a drier area before its would-be rain can rail, the moisture evaporates once more and the cloud disappears.
Scientists note their new work does not contradict previous findings that suggest global warming might lead to more tropical storms, because there is far less particulate(微粒的)pollution over the oceans.
60. The first paragraph mainly talks about        .
A. the results of vehicle pollution
B. an introduction to particles from car exhausts
C. less wind energy in polluted regions
D. less water caused by vehicle pollution
61. From this passage we can learn that        .
A. scientists supported their idea by using material models
B. the new study is contrary to the previous findings
C. if there are more particles in the atmosphere, there will be more raindrops
D. there is a cause and effect relationship between wind speeds and particle pollution
62. The underlined word “induce” in Paragraph 3 most probably mean       _ .
A. reduce         B. persuade           C. cause             D. produce
63. What’s the best title for the passage?
A. Pollution and Global Warming          B. Car, Wind and Rain

An ichthyologist is a scientist who studies fish. Most people who do this job say they love their work because it is very rewarding and varied. They work not only inside a laboratory, but also out in the field. Fieldwork includes traveling to rivers, oceans and lakes in order to collect information and specimens(样本), Reading, writing and speaking are also very important to the job. Fish scientists need to read the research of other scientists. They must he able to write up their own research clearly so that others can follow it. They also need to be able to give lectures about their findings, so that they can spread knowledge.
Ichthyologists who wish to specialize can choose any one of three areas of study. The first area is aquaculture  (水产养殖). This involves the study and practice of fish farming and management. Because it is a rather new study, there are very few job opportunities available. However, as there is so much to discover, many see it as an exciting area for a new ichthyologist to enter. The second area is fisheries science, which means working with a team of scientists to find out more about different fish species. The third area is about the protection of natural fish populations. This is very important today, given that many fish species are in danger of dying out because of the actions of humans.
To become a successful fish scientist, you need to have a curious mind and be able to work on your own. You also need to be able to handle equipment and perform experiments; but most importantly, you must love fish. To become an ichthyologist, you will need to train at a university to pass a Bachelor of Science degree. For this, you will need to be good at mathematics, physical science and biology. Then, you will need to study for another year to complete an honours degree in ichthyology. This honours degree contains coursework about all aspects of fish. You also need to complete a research paper.
68. What makes the jobs of ichthyologists so varied?
A. They study fish habits and collect information.
B. They have to study science and mathematics.
C. They work in fields as well as in laboratories.
D. They read research papers written by others.
69. Which of the following statements is NOT true according to the passage?
A. An ichthyologist has an interesting and varied profession.
B. Aquaculture is the study of fish protection.
C. The life of an ichthyologist can involve lots of travel.
D. A fish scientist needs to be independent and curious about things.
70. Who is most likely to become an ichthyologist?
A. Tom, because he likes fishing and outdoor sports.
B. Jack, because he likes to travel and read adventure books.
C. Jenny, because she likes science, mathematics and reading about dinosaurs.
D. Jane, because she likes mathematics, science, biology and searching rock-pools.
71. The passage is probably written for         .
A. university students                        B. science researchers
C. fisheries experts                          D. fish farmers

As far as I am concerned, my suggestion is that we   51   always have a notebook and a Chinese-English dictionary within easy reach. Whenever   52   beats(难倒) us, we can first put it down in our notebook and then look it up in our dictionary. We can also turn to our English teacher for   53  , if necessary.
In short, I believe that it is of   54   use to keep a diary in English for the development of our   55   skills.

阅读下面短文,掌握其大意,然后从36—55各题所给的四个选项(A、B、C和D)中,选出最佳选项
In a class I teach for adults, I recently did the “unpardonable.” I gave the class homework!

At the   43   of our next class, I asked if someone wanted to   44   what happened when they told someone they loved them. I fully expected one of the   45   to volunteer, as was usually the   46 , but on this evening one of the men raised his hand. He appeared quite moved and a bit   47  . As he unfolded out of his chair, he began by saying, “Dennis. I was quite   48   with you last week when you gave us the assignment. I didn’t feel that I had   49  to say those words to and   50 , who were you to tell me to do something that personal? But as I began driving home my conscience (良知) started talking to me. It was telling me that I   51   exactly who I needed to say I love you to. You see, five years ago, my father and I had a heated   52   and really never resolved it since that one. We   53  seeing each other unless we absolutely had to at Christmas or other family gatherings. But   54   then, we hardly spoke to each other. So last.

第二部分阅读理解(共20小题,每小题2分,满分40分)
A
Too often we accuse others of not listening, pretending that we ourselves are faultless, yet in our hearts we know that many of the mistakes we make come about because we haven’t listened carefully enough. We get things wrong because we haven’t listened carefully enough. We get things wrong because we haven’t quite understood what someone meant when they were talking to us. Anyone who has ever taken the minutes of a long meeting will know how hard it is to remember-- despite the benefit of notes-- exactly what everyone said. But success depends on getting things right--and that means listening.
Listening is not the same thing as hearing; it is not an effort actively. It demands attention and concentration. It may mean quizzing the speaker for additional information or for clarification------ it is always better to ask than to continue regardless and get things wrong. However, if you allow your mind to wander onto something else, even for a few minutes, you’ll miss what the speaker is saying------ probably at the very moment when he or she is saying something critical. And not having heard, you won’t know you’ve missed anything until it’s too late.
The most common bad habit we have is to start thinking of what we are going to say about the subject long before the other speaker has finished. We then stop listening. Even worse, this often adds rudeness to inattentiveness, as once you have decided what to say there is a fair chance you will interrupt to say it. Good listeners don’t interrupt. In fact it is often worth explaining the main idea of what you have just been told before going on to make your own points. Nobody is offended by this and it shows that you have listened well.
Above all be patient and accept that many people are not very good communicators. It’s helpful to remember that the ways people move and position themselves while they are speaking can reveal a great deal about what they are saying. Equally important you should put yourself in the other person’s place, both intellectually and emotionally; it will help you to understand what they are getting at and form a response. But don’t be too clever. Faced with a know-all, many people keep quiet because they see no point in continuing.
56. Which is the best title for this passage?
A. Don’t be too clever                B. Be a good listener.
C. Don’t miss anything critical            D. Think of the speaker
57. In the last paragraph, “…… what they are getting at ……” means________ .
A. what they imply                             B. what they like
C. what they attack                             D. what they achieve
58. What is the writer’s opinion?
A. If you want to be a good listener, you should be very clever and emotional.
B. Speakers won’t continue talking when their listeners explain what they’ve heard.
C. If you don’t want to get things wrong, it’s important to be a good listener,
D. It’s hard to be a good listener because listening tests you on your intelligence.
59. What is the lesson we can learn from this passage?
A. Don’t accuse others of not listening while talking with them.
B. Don’t get anything wrong if you miss what the speaker is saying.
C. Listening inattentively may cost you the loss of your success.
D. Think carefully of what you’re going to say before the speaker finishes.

B
Fear and its companion pain are two of the most useful things that man and animals possess if they are used. If fire didn’t hurt when it burned, children would play with it until their hands were burned away. Similarly, if pain existed but fear didn’t, a child could burn itself again and again because fear would not warn it to keep away from the fire that had burnt it before. A really fearless soldier—and some do exist—is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which man and animals might soon die out.
In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. The important thing is not to let fear rule you, but instead, to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take.
In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is well.
In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing into your house, and you may not want to go and live in a desert where there are no airplanes. In this case, fear has given you its warning, you have examined it and decided on your course of action, so fear of the particular danger is no longer of any use to you, and you have to try to overcome it.
60. Children would play with fire until their hands are burnt away if _________.
A. they were not well educated at school   B. they had never played with fire before
C. they had no sense of pain             D. they were fearful of pain
61. People sometimes succeed in timely avoiding danger because _________.
A. they have gained experience     B. they are warned of the danger and take quick action
C. they jump out of the way in time  D. they are calm in face of danger
62. What is implied but not stated in the passage?
A. Too much fear is harmful              
B. Fear is always something helpful
C .Fear is something that can be avoided     
D. Fear ought to be used as our guide in our life
63.The best title for this passage should be __________.
A. No Pains, No Gains          B. Pain and Actions
C. The Value of Fear         D .The Reason Why People Fear

Two Earthquakes in Two Months:
Comparing the Quakes in Haiti (海地) and Chile (智利)
Overview (概要) How do the earthquakes in Chile and Haiti compare? Here, students perform a gallery walk to learn more about the earthquakes from a specific point, and then do a specific research and presentation project or response activity. Finally, they seek answers to their unanswered questions.
Materials Print copies of photographs, charts, documents and other visuals to display, as described below; computer (s) with Internet access (optional), research materials, handouts.
Warm-up Choose and prepare a “gallery” of photographs, graphics, news reports and other materials to display around the room to enable students to consider the 2010 earthquake in Chile.
Depending on course program, choose materials for the gallery that provide a window on the two quakes, through one of the following specific points, or the focus of your choice:
Earthquakes through History Putting the 2010 Chilean and Haitian quakes into historical view related to other earthquakes, including the 1960 Chilean quake and the 2004 Asian earthquake and tsunami.
Rescue and Aid Considering domestic and international response to the disasters by militaries, governments and aid organizations, including rescue and recovery as well as efforts to provide food, water, health care and shelter to those affected.
Related The article Underwater Plate Cuts 400 Mile Gash compares several earthquakes:
Mr. Lin figured that the quake on Saturday was 250 to 350 times more powerful than the Haitian quake.
But Paul Caruso noted that at least on land, the effects of the Chilean tremor (震动) might not be as bad. For one thing, he said, the quality of building construction is generally better in Chile than in Haiti. And the fact that the quake occurred offshore should also help limit the destruction. In Haiti, the rupture (断裂) occurred only a few miles from the capital, Port-au-Prince. The rupture on Saturday was centered about 60 miles from the nearest town, Chillan, and 70 miles from the country’s second-largest city, Concepción.
Read the article using the following questions.
Questions For discussion with others and reading comprehension:
How does the 2010 Chilean earthquake compare to the 1960 Chilean earthquake?
Why do scientists believe that the 2010 Chilean earthquake will not cause the same level of damage as January’s Haitian earthquake did?
How does the 2010 Chilean earthquake compare to the 2004 Indonesian earthquake?
What reasons do scientists give to explain why the Indonesian quake caused so much more damage than the recent Chilean earthquake?
64. Which of the following shows one of the reasons for slighter losses in Chile than in Haiti?
A. Position:
     
B. Power:

65. We can infer that the article Underwater Plate Cuts 400 Mile Gash includes ________.
A. the causes of the 2010 Chilean earthquake and the 1960 Chilean earthquake
B. the comparison between the 2010 Haitian and the 2004 Indonesian earthquakes
C. the reason for the 2010 Chilean quake being more powerful than January’s Haitian earthquake
D. the reason for less damage in the 2010 Chilean quake than in the 2004 Indonesian earthquake
66. What is the passage most likely to be?
A. A program for research.                                   B. A guide to earthquake study.
C. An advertisement for students.                             D. An introduction to quakes.

D
Many disease researchers have warned that rising global temperatures could lead to more diseases. for example by allowing tropical diseases to expand their ranges into what are now mild regions. This is a particular fear for the diseases carried by insects such as malariac(疟疾) and
sleeping sickness.
But the reality is more complex, argues Kevin Lafferty. a disease ecologist. He argues that a warming climate could favour some diseases in certain regions while controlling them in others.
Lafferty does not deny that climate change might allow malarial mosquitoes to spread to new areas. However he believes that hotter and drier conditions may also get rid of mosquitoes from areas where they currently exist. If this were the case, he says. there would be little. if any, net
increase (净增长) in the risk of disease.
In addition, many mild regions such as southern Europe or the southern U.S. have good sanitation(卫生设备) and insect control programmes which, Lafferty says, would prevent diseases from becoming common even if climatic conditions were suitable.
Finally, he argues, climate change could wipe many species off the plant. Infectious pathogens(病原体) depend on their hosts for survival so they too may become endangered-especially if they,like malaria, rely on more than one host.
But Mercedes Pascual of the University of Michigan points out that there are large human populations in the east African highlands, just outside of the existing range of malarial mosquitoes.She said as temperatures rise, the mosquitoes will reach these areas. So the disadvantages will
outweigh the advantages of decreased risk elsewhere.
Most of the ecologists do, however, seem to agree on one point: predicting where a disease is going to go next involves far more than just considering climate. No matter what the results of the debate are, they all agree that health concerns should continue to play a critical role in climate policy and the debate shouldn't be regarded as weakening the case for action against global warming.
53. According to Kevin Lafferty, climate change__________
A. will not increase the spread of insect-bome diseases
B. may not significantly increase the risk of disease in the whole world
C. will not affect the dry regions where sanitation is good
D. may not affect viruses that depend on more than one host
54. What does Mercedes Pascual think of Lafferty 's conclusion?
A. She disagrees with it.   B. She supports it.
C. She is not sure ofit.    D. She thinks it needs proving.
55. We may infer from the passage that ___________
A. climate is the only factor in the predictior of the spread of diseases
B. when making a climate policy one should take health into account
C. the debate mentioned in the passage furthers the debate on global warming
D. a policy should be made immediately to try to stop climate change
56. We can learn from the passage that ___________
A. all the disease researchers agree that climate change will spread disease
B. nothing can be done to stop the present global warming
C. scientists have found ways to stop the wild spread of disease
D. ecologists have different views on whether the global warming will spread diseases further
