As a girl, she was inspired by the work of great scientists: she read the story of the cure of malaria in the Panama Canal; she also read a biography of Madame Curie．These accounts inspired her to pursue a career in scientific research．After high school, she worked for the Michigan Department of Health, where she did research in biology and microbiology．There, her colleagues saw her talent and encouraged her to pursue science as a career．She went on to earn a bachelor’s degree from Michigan State University in 1948 in medical technology．When she began working at Michigan State in the early 1960s,
she was balancing the demands of scientific research with the needs
of her family．At that time both of her children were in school．She
would work in the lab in the morning while they were at school,
go home to see them at lunch, return to the lab for the afternoon, go
home for dinner, and return to the lab in the evening, if necessary．
At that time, there were fewer women scientists working than
there are today, but she encountered several in her career．At the
Michigan Department of Health, many of her colleagues were women and, consequently, she did not feel isolated because of her gender–nor did she feel that she was treated differently because she was a woman．
While working at Michigan State, she also felt that she was treated with respect by her peers．Her colleagues, among them doctors and Ph．D．chemists, all treated her as an equal．On the whole, she believes that there is not a great deal of difference between men and women in science．
56．Why does the woman scientist refuse to let out her name?
A．Because she is a shy lady．
B．Because she doesn’t mind her fame．
C．Because she never takes pride in her research．
D．Because she never works for her fame．
57．What is the noble lady scientist really interested in?
A．The life stories of other women scientists．
B．Biology and microbiology．
C．The secret of the success of the other scientists．
D．The difference between men and women scientists．
58．Who helped and encouraged her to carry on her scientific research?
A．Her family and friends． B．Madame Curie．
C．Her colleagues and other scientists． D．Some of the officials．
59．What is the whole passage mainly about?
A．The life story of a famous woman scientist with great success．
B．A brief introduction about an unknown great woman scientist．

Plants, like animals, are subject to diseases of various kinds．It has been estimated that some 30,000 different diseases attack our economic plants; forty are known to attack corn, and about as many attack wheat．The results of unchecked plant disease are all too obvious in countries which have marginal food supplies．The problem will soon be more widespread as the population of the world increases at its frightening rate．Even in countries which are now amply fed by their agricultural products there could soon be the major crops; the resulting famines(饥荒) could kill millions of people, and the resulting hardship on other millions could cause political upheavals(动乱) disastrous to the order of the world．
Some plants have relative immunity to a great many diseases, while others have a susceptibility to them．A blight (萎菌病) may be but a local infection easily controlled; on the other hand it can attack particular plants in a whole region or nation．An example is the blight which killed virtually every chestnut tree in North America．Another is the famous potato blight in Ireland in the last century．As a result of that, it was estimated that one million people died of starvation and related ailments．
Plant pathologists have made remarkable strides in identifying the pathogens of the various diseases．Bacteria may invade a plant through an infestation of insect parasites carrying the pathogen．A plant can also be inoculated by man．Other diseases might be caused by fungus which attacks the plant in the form of a model or smut or rust．Frequently such a primary infection will weaken the plant so that a secondary infection may result form its lack of tolerance．The symptoms(症状) shown may cause an error in diagnosis, so that treatment may be directed toward bacteria(细菌) which could be the result of a susceptibility caused by a primary virus infection．
小题1:How many diseases are known to attack wheat?
| A．Around 30000 | B．Forty |
| C．Around 29960 | D．Around 40 |
| A．food shortages in poor country | B．food shortages in rich country |
| C．increase of world population | D．disaster in world politics |

Organic foods are produced according to certain production standards, meaning they are grown without the use of conventional pesticides, or chemical fertilizers and that they were processed without food additives. Livestock are raised without the routine use of antibiotics（抗生素）or growth hormones. In most countries, organic produce must not be genetically modified. They may also be required to be produced using energy-saving technologies and packaged using recyclable materials when possible.
Early consumers interested in organic food would look for non-chemically treated, fresh or minimally processed food.
They mostly had to buy directly from growers: “Know your farmer, know your food” was the motto. Personal definitions of what constituted ( 组成)“organic” were developed through first-hand experience: by talking to farmers, seeing farm conditions, and farming activities. Historically, organic farms were relatively small family-run farms — which is why organic food was once only available in small stores or farmers’ markets.
However, since the early 1990s organic food has had growth rates of around 20% a year. As of April 2008, organic food accounts for 1 - 2% of food sales worldwide. Currently organic food production is legally regulated. Many countries require producers to obtain organic certification in order to market food as organic.
Several studies have attempted to examine and compare conventional and organic systems of farming. The general consensus（共同看法）is that, in the short term, organic farming is less damaging for the following reasons:
● Organic farms do not release synthetic pesticides (合成农药) into the environment — some of which have the potential to harm soil, water and local wildlife.
● Organic farms are better than conventional farms at keeping diverse ecosystems, i.e., populations of plants and insects, as well as animals.
● Organic farms are more energy efficient and produce less waste.
Another report published in March 2008 by The Organic Center claims that organic food is on average 25% more nutritious than conventional food.
However, many critics believe that the increased land needed to farm organic food could potentially destroy the rainforests and wipe out many ecosystems. And organic products cost 10 to 40% more than similar conventionally produced products. Processed organic foods in supermarkets are 65% more expensive.
1. Early consumers knew what food was “organic” by _______.
A. firsthand experience B. the “certified organic” label tag
C. its packaging D. examining its organic certification
2. We can infer that _______.
A. in America, organic food can only be bought in small stores or farmers’ markets
B. organic food is also available in large supermarkets at present
C. organic food is produced by large-scale farms
D. organic food is often beautifully packaged
3. According to the passage, organic food is considered as _______.
A. junk food B. delicious snacks C. green food D. conventional food
4. What is the main idea of the last paragraph?
A. The benefits of organic food. B. The cost of organic food.
C. The disadvantages of organic food. D. Organic food and conventional food.
5. Which of the following statements does NOT support the view that organic farming is more environment-friendly?
A. Organic food is generally thought to be more nutritious.
B. Organic farms are more energy efficient and produce less waste.
C. Organic farms are better than conventional farms at maintaining varieties of plants, insects and animals.
D. Organic farms do not release synthetic pesticides into the environment.
Findings from a new study were presented at a recent meeting of the American Psychosomatic Society. Researchers in the United States studied one hundred thousand women during an eight-year period, beginning in nineteen ninety-four. All of the women were fifty years of age or older. The study was part of the Women’s Health Initiative organized by the National Institutes of Health.
The women were asked questions that measured their beliefs or ideas about the future. The researchers identified each woman’s personality eight years after gathering the information.
The study found that hopeful individuals were fourteen percent less likely than other women to have died from any cause. The hopeful women were also thirty percent less likely to have died from heart disease after the eight years.
Hilary Tindle from the University of Pittsburgh School of Medicine in Pennsylvania was the lead author of the report. She said the study confirmed earlier research that linked optimistic feelings to longer life.
The researchers also gathered information about people’s education, financial earnings, physical activity and use of alcohol or cigarettes. Independent of those things, the findings still showed that optimists had less of a chance of dying during the eight-year period.
Some women who answered the questions were found to be cynically hostile, or highly untrusting of others. These women were sixteen percent more likely to die than the others. They also were twenty-three percent more likely to die of cancer.
The study also found that women who were not optimistic were more likely to smoke and have high blood pressure or diabetes. They were also more likely not to exercise.
Professor Tindle says the study did not confirm whether optimism leads to healthier choices, or if it actually affects a person’s physical health. She also says the study does not prove that negative emotions or distrust lead to bad health effects and shorter life. Yet there does appear to be a link that calls for more research.
1. What’s the purpose of carrying out the study?
A. To gather information for the National Institutes of Health.
B. To find out the relationship between women’s personality and their health.
C. To decide who is more likely to enjoy happier life.
D. To identify each woman’s personality 8 years after gathering the information.
2. What can be inferred from the passage?
A. It’s uncertain whether optimism affects a person’s physical health.
B. Negative emotions do cause shorter life.
C. The connection between personality and health has been established.
D. The more optimistic you are, the longer life you may enjoy.
3. According to the passage, who is more likely to die of cancer?
A. A woman who has high blood pressure or diabetes.
B. A woman who doesn’t exercise.
C. A woman who has poor physical health.
D. A woman who always doubts what others say.
4. Which of the following is true?
A. American Psychosomatic Society organized the new study.
B. Women who were optimistic were less likely to smoke.
C. More questions were given than those measuring women’s beliefs or ideas.
D. Hopeful women were 16% less likely to die from heart disease.
第二部分：阅读理解（共20小题;每小题2.5分，满分50分）
阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
Proper arrangement of classroom space is important to encouraging interaction. Most of us have noticed how important physical setting is to efficiency and comfort in our work. College classroom space should be designed to encourage the activity of critical thinking.
We have entered the 21st century, but step into almost any college classroom and you step back in time at least a hundred years. Desks are normally in straight rows, so students can clearly see the teacher but not all their classmates. The message behind such an arrangement is obvious. Everything of importance comes from the teacher.
With a little imagination and effort, unless desks are fixed to the floor, the teacher can correct this situation and create space that encourage interchange among students. In small or standard-size classes, chairs, desks, and tables can be arranged in a variety of ways. The primary goal should be for everyone to be able to see everyone else. Large classes, particularly those held in lecture halls, unfortunately, allow much less flexibility.
Arrangement of the classroom should also make it easy to divide students into small groups for discussion or problem-solving exercises. Small classes with movable desks and tables present no problem. Even in large lecture halls, it is possible for students to turn around and form groups of four to six. Breaking a class into small groups provides more opportunities for students to interact with each other, think out loud, and see how other students’ thinking processes operate all essential elements in developing new modes of critical thinking.
In courses that regularly use a small group format, students might be asked to stay in the same small groups throughout the course. A colleague of mine, John, allows students to move around during the first two weeks, until they find a group they are comfortable with. John then asks them to stay in the same seat, with the same group, from that time on. This not only creates a comfortable setting for interaction but helps him learn students’ names and faces.
1. The primary purpose of desk rearrangement is _______.
A. for the teacher to divide students into small groups.
B. to make it possible for students to interact with each other.
C. for the teacher to find out how students think.
D. to give students more opportunities to practice speaking.
2. The expression “step back in time at least a hundred years” in Paragraph 2 is intended to convey the idea that _______.
A. there is not much change in educational idea over the past hundred years
B. critical thinking was encouraged even a century ago
C. college classrooms often remind people of their college life
D. a hundred years ago, desk arrangement in a classroom was quite different
3. The greatest advantage in allowing each student to find his own group might be that________
A. learning is made comfortable in this way
B. the teacher can easily remember students’ names and faces
C. the teacher saves the trouble in doing that
D. brighter students can help slower ones.
4. It is implied in the passage that ______.
A. students are allowed to changed groups throughout the course in John’s class
B. classroom interaction between students is essential to the teachers
C. a comfortable environment leads to higher working efficiency
D. new kinds of desks and chairs should be made
5. The author mentioned John in the last paragraph in order to ________
A. create a comfortable setting for interaction
B. introduce an approach of learning students’ names and faces easily
C. give an example that students stay in the same seat throughout the course.
D. describe a good seat-arrangement mode in courses with small group format.
