When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction. 
Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that these figures are conservative (保守的). One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise.
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine biologists, that of the “shifting baseline”. The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
【小题1】The aim of the extinction of large prehistoric animals is to suggest that _______.

The United Nations Children’s Fund (UNICEF) has declared October 15 as Global Handwashing Day in 2005．The first Global Handwashing Day is on October 15 of 2008.Activities are planned over twenty countries to get millions of people in the developing world to wash their hands with soap. Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the UN Children's Fund, American government agencies, the World Bank and soap makers Unilever and Procter and Gamble. The goal is to create a culture of hand washing with soap.

Hand washing can prevent the spread of disease. Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.

When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.

The organizers say all soaps are equally effective at removing disease-causing germs. The correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds.Then, rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air. Soap is important because it increases the time that people spend washing. It also helps to break up the grease and dirt that hold most of the germs.And it usually leaves a pleasant smell,which increases the likelihood that people will wash again.

Washing with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea(痢疾) by almost half. And it could reduce deaths from pneumonia and other breathing infections by one-fourth. Diarrhea is the second leading cause of child deaths, killing more than one and a half million children a year. Pneumonia is the leading cause, killing about two million children under five each year. Hand washing can also prevent the spread of other diseases.

50.We can learn from Paragraph 1 that _______.

A.the first Global Handwashing Day was held in 2005

B.many originations support the idea of Global Handwashing Day  

C.Global Handwashing Day was founded by many soap makers

D.the content of Global Handwashing Day is to wash your hand frequently

51.The underlined phrase “critical moments” in Paragraph 2 refers to _______.

A.the turning points    

B.schedules  

C.the arrangement of a time

D.the necessary parts in health

52.The main purpose of the story is to tell us ________.

A.hand washing is very important

B.to create a culture of hand washing with soap

C.germs can infect ourselves and others

D.soaps play an important role in everyday life

53.The last paragraph implies that ___________.

A.a soap is a kind of medicine to prevent a disease

B.it is important for children to wash hands in a correct way

C.Pneumonia kills about two million children each year

D.Diarrhea is the second leading cause of child deaths.

根据文章内容,从下面A．B．C．D．E．F六个选项中选出能概括每一段主题的最佳选项, 选

项中有一项是多余选项．

    Effective reading should adopt a correct way, and then you can get more by paying less．Here are some hints for reading effectively．

___________

Don’t choose a rather difficult book or a too easy one for yourself to read．A book full of new words will make you feel discouraged quickly．To understand those new words, you have to turn to the dictionary quite often．It seems that you are not reading the book but the dictionary．It has no fun at all! On the contrary, a too easy one will only waste your time and cannot do any help．The two extremes may at last make you give up reading．So it’s better for you to find a proper book with no more than five new words on each page．

_____________

If you come across a new word, do not look it up in a dictionary as quickly as possible．Leave it alone and guess the meaning of it based on the content of the text．        This ability is quite necessary in reading．If you know your guess is right later, you will be highly excited at your “success”, and your interest in reading is well stimulated．If a word really hinders you from understanding the whole passage, turn to the dictionary by then．I am sure you can remember this word very well, as it has left you such a deep impression for its “troublesome image．”

___________

To comprehend what you are reading, you should think while you are reading, then from your own ideas on some special issues．Try to scribble some lines-a very short journal, to express your ideas．Your writing does not need to be quite formal but expressive．This practice can make you communicate with the original English authors．Day by day, your way of thinking in English will turn into a native way, which is quite important for English writing．

_____________

Language has its own beauty, no matter Chinese or English．Don’t merely take English as a “test”．Take it as an “entertainment” instead and you will enjoy it through learning．

Maybe you should find some beautiful literary works such as a prose or a poem to read, if you like．Try top read them as loudly and impassionedly as you can．During this process, not only you can enjoy yourself by the great emotions of the writers, but also your pronunciation and your manner of speaking English will be improved．

______________

The last but not the least, keep on reading．If you cannot keep it as a habit, you will suffer from paying without gaining．

第三部分阅读理解（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳答案。
Governors, lawyers and business leaders have to deal with scientists, and every educated person finds his views affected by science. Yet our science teaching of non-scientists, in school and college, has built up mistaken ideas, dislikes, and the common boast(自夸), "I never did understand science." Even those students who arrive at colleges with plans to become scientists usually bring a mistaken picture of science: some have a collection of unorganized facts about science, and some regard the study of science as a game which includes getting the right answer.
The first of these attitudes seems to come from a kind of course which provides various kinds of information; the second, from a training course on how to pass examinations that do not ask about the student's understand but simply require him to put the numbers in the right formula(公式). Neither type of courses in school or college seems to give students an understanding of science as we find it among scientists. Neither shows students how real scientists work and think, how the facts are gathered, how discoveries are made, and what they mean. Young people need good teaching of science, not so much as great wealth of knowledge as a healthy understanding of the nature of science. They need an understanding of knowledge leading to agreement with science and an eagerness of the way scientists work. Given these it is easy to encourage later reading and learning.
56. One of the reasons that cause mistaken ideas of science is due to _______.
A. a mistaken picture in students' mind       
B. the unscientific way of teaching of science
C. the fact that students fail to see the influence of science
D. the fact that students have a collection of unrelated facts about science
57. According to the passage, we can safely say that the subject of the passage is ______.
A. need for good science teaching              
B. young people should form a correct attitude to science
C. students must know what science is and how scientists work and think
D. every person, including governors, lawyers and business leaders should study science
58. A good course of science is ______.
A. to provide students with all kinds of information
B. to teach students to do things according to formulas
C. to help students have a good understanding and form a correct attitude to science
D. to encourage students to make themselves masters of knowledge
59. People such as governors, lawyers and business leaders deal with scientists mainly because ______.
A. scientists are great persons                           
B. they owe much to scientists' contributions
C. they can be affected by scientists when they are together
D. scientists make discoveries and help people live a more comfortable and safer life
