A vegetarian（素食者）diet may help to protect people against cancer, a UK study suggests. Analysis of data from 52,700 man and women shows that those who did not eat meat had significantly fewer cancers than those who did.
Published in American Journal of Clinical Nutrition, the findings were worth looking into .Although it is widely recommended that people eat some fruits and vegetables every day to reduce their risk of cancer and other diseases, there is very little evidence showing that a vegetarian diet can surely reduce cancers .
But surprisingly, the researchers also found a higher rate of colorectal（直肠的）cancer – a disease connected with eating red meat – among the vegetarians.
Study leader Professor Tim Key, a researcher at the University of Oxford, said no previous study had looked at the diet in this way and that there had been a lot of confusion about the issue.
“It’s interesting – it suggests there might be some reduction in cancers in vegetarians, but we need to look carefully at that”, said the professor.
More work is needed to show the connections between diet and cancer but such studies are very hard to do. Dr Joanne Lunn, a senior nutrition scientist at the British Nutrition Foundation, said the findings highlighted the fact that cancer is a complex disease and many different lifestyle factors play a part in determining a person’s risk.
73. What would be the best title for the passage?
A. Reasons for getting cancers.
B. Vegetarians get fewer cancers.
C. Tips on avoiding cancers.
D. A surprising discovery on colorectal cancer.
74. Why are the findings worth looking into?
A. They can encourage healthy eating.
B. They show that cancer is a complex disease.
C. they show a brand new discovery.
D. They have been published in American Journal of Clinical Nutrition.
75. We can learn from the passage that _________.
A. people eating red meat are unlikely to get colorectal cancer
B. the diet is one of the many factors that determine a person’s health
C. the connections between a vegetarian diet and cancer are clear through the research
D. scientists will soon figure out the relationship between the diet and cancer |

第三部分阅读理解（共15小题；每小题2分，共30分）
(A)
It is easier to start to learn a new language than to become good at it. I’ve started to learn many new languages, such as French, Spanish, Italian, Russian, Afrikaans (南非荷兰语), and so on. I can’t speak them yet, but I’ve started picking up a few words and phrases that help me when I’m visiting. Most importantly, I’ve had fun doing this.
I’ve started to learn Italian, but I haven’t learned any Italian grammar, and when I visit Italy I’m not able to speak Italian correctly. My aim is just to communicate at a very basic level when I visit a country, to make an effort, and to show appreciation of the language and culture. I’m not trying to talk about politics or explain my views on life. I pick key or useful words and phrases that I want to learn. For example, as a visitor to another country, the key words in a foreign language are the words which will be of the most use to you and which you will use most often. These key words and phrases will vary from visitor to visitor, depending on the purpose of their trip.
It is worth remembering that it is easier to start a task than to finish it, and the same goes for learning a new language. The better you are at it, the slower your rate of progress will be, as you have to learn grammar, words and so on. If you are only trying to learn a few foreign words and phrases, you will make faster progress, have more fun, and won’t have to spend too much time on any given language.
61. From the second paragraph, we can infer that ______.
A. the writer is good at Italian, although it is rather difficult
B. the writer doesn’t like learning Italian because it is no fun
C. discussing politics or explaining one’s view requires an advanced language level
D. it is great fun to communicate with the local people in another country
62. Which of the following does the writer prefer to learn?
A. Sentence structure. B. Important words and phrases.
C. Complicated sentences. D. Grammar.
63. You can make faster progress ______.
A. if your language level is advanced B. if you only try to learn some basic words
C. once you speak the language well
D. once you have mastered several other languages
64. Which of the following would be the best title of this passage?
A. Starting Learning a New Language Is Easier than Becoming Good at It
B. How to Visit a Foreign Country
C. The Importance of Learning a Foreign Language
D. Why You Should Learn Several Foreign Languages |

Education is not only the teaching and learning of 36 , but also the developing of a person"s 37 .
Now liberal(开明) education has a great 38 on the world. Much work has been done to 39 better ways of teaching. Students are 40 to have their own thoughts and their own ideas when they have lessons which are often held in the form of group discussions. They are 41 guided to use the knowledge 42 . In liberal education punishment 43 exists. Teachers and students are just like 44 . The idea is of course a perfect one if it can really be carried out. However, it only 45 in the imagination and will never be 46 . We must admit that children should 47 be guided properly.

In the United States, teaching is very important. If teachers do not teach well, students complain. If many students do not understand, people think that the teacher does not do a good job. The teacher has big responsibility to make sure students understand. In a sense, students are consumers and the teacher is offering services.
Students have the right to evaluate their teachers, and they usually do so at the end of each course. That evaluation includes lots of aspects of teaching, such as explanation, preparation, using good examples, answering questions, and organization of classes.
Students are supposed to read required textbooks and recommended books before classes. Without reading them, they will find it very difficult to understand the class. Basic courses on doing research and writing papers are taught at the beginning of the program. They teach things very concretely(具体地) and clearly. Students are expected to apply what they have learned to their studies.
Classes are usually divided into lectures and seminars. There are some lecture classes, where the teacher just gives a lecture, and students ask questions at the end. Most graduate level classes are lectures and discussions. Participating in discussions is very important. Higher level classes involve very little lecturing. They emphasize discussion and presentation by the students.

Most shops in Britain open at 9:00 am, and close at 5:00 or 5:30 in the evening. Small shops usually close for an hour at lunchtime. On one or two days a week—usually Thursday and/or Friday—some large food shops stay open until about 8:00 pm for late night shopping.
Many shops are closed in the afternoon on one day a week. The day is usually Wednesday or Thursday and it is a different day in different towns.
Nearly all shops are closed on Sundays. Newspaper shops are open in the morning, and sell sweets and cigarettes as well. But not all the things can be sold on Sundays.
Usually it is not difficult for foreign visitors to find where to buy things. Most shops sell the things that you want to buy. One problem is stamps. In Britain you can only buy these at post offices. Many large food shops are self-service. When you go into one of these shops, you take a basket and you put the things you wish to buy into this. You pay for everything just before you leave. If anyone tries to take things from a shop without paying they are almost certain to be caught, because most shops have detectives.
When you are waiting to be served in a shop, it is important not try to be served before people who arrive before you. Many foreign people are surprised at the British way of queuing (排队).

As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.
When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.
There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.
1. The author says that the world population is increasing because _____.
A. there are many rich valleys and large fields
B. farmers are producing more crops than before
C. people are living longer due to better living conditions
D. new lands are being made into farmlands
2. The author says that in areas with large populations, land might be more productively farmed if _____.
A. the land was divided into smaller pieces
B. people moved into the countryside
C. industrial methods were used in farming
D. the units of land were much larger
3. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.
A. growing new types of crops
B. irrigation and dry-farming means
C. providing fertilizers
D. destroying pests and diseases
4. Why is the land divided into tiny units in some areas?
A. There are too many people living there.
B. It saves more natural resources there.
C. It prevents crops from serious diseases there.
D. Farmers can grow various kinds of crops there.
5. Why do some people use dams to hold back waters from great rivers?
A. To develop a new kind of dry-farming methods.
B. To prevent crops from floods.
C. To provide water and electricity in all seasons.
D. To water poor lands in bad weather. |
