Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones, substances found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure.
Dr. Scott Small is a professor of neurology (神经病学) at Columbia University in new York City. He is the lead writer of a research paper describing the effects of cocoa flavones on brain activity. His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study. Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memory tests.
The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the lead researcher of a four-year study involving 18,000 adults. This study will use flavones capsules(胶囊). The study subjects will be divided into two groups and will take two pills per day. The capsules used will all look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo
Dr. Manson says it's not necessary for people to start eating more chocolate, because a person would have to eat a huge amount of chocolate to get the same level of flavones given to the rest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarly, Dr. Manson says a cocoa-based flavones extract(提取)may be developed in the future But he says that more studies are needed to see how much flavones is good for our health.
1.What was done to the subjects after Dr. Small’s study?
A. They were asked to take a high-level flavones drink.
B. They were given capsules containing flavones.
C. They were given brain imaging and memory tests.
D. They were asked to take two pills of flavones capsules per day.
2.What's the similarity of the two experiments?
A. Both use high-level flavones capsules.
B. The number of the subjects is the same.
C. Drinks and placebos are used in both experiments.
D. The subjects are divided into two groups in both experiments.
3.Why will Dr. Manson carry out the four-year study?
A. To prove the first experiment is wrong.
B. To carry out the experiment further.
C. To test how much flavones can improve our memory.
D. To show eating chocolate is better to improve memory.
4.What can we learn from the last paragraph?
A. It’s not necessary for us to eat chocolate.
B. The more we eat flavones, the better our health will be.
C. In the future we can get flavones without eating chocolate.
D. It’s easy for people to get the same level of flavones given to the test subjects.

It is time for students to sell such things as chocolate bars and greeting cards to raise money for their school, class or club. It is inevitable that they will knock on your door and you will easily hand over your cash for overpriced items that you really do not want. That is okay, though, because there are many reasons why children should be allowed to raise money for their schools and clubs.
Fundraising(募集资金) is a great way to help children learn social skills. It is not easy to go up to a complete stranger and ask him for his money. They have to nicely ask for help, show the interested buyer what they have to offer and explain how it will help them in school. If someone refuses to buy an item, that child has to take the failure in stride(不特别费力地), and that is a learning lesson as well.
Students can learn how to deal with money by fundraising. Of course, it might seem safer for us to take charge of our children’s earnings from their fundraising before it is turned into the school. However, by making them keep track of it, count it, and make sure everyone pays the right amount, they are learning an important lesson. Dealing with money is important to know about when they are older.
Fundraising helps improve their schools. It is the children’s school. They have to learn there and grow there. Why not let them help in making it a better place?
Fundraising allows for more life experiences for the child. The raised money is used towards things like parties, trips, or for the music club to go to see a Broadway play. The children receive the rewards for their hard work at raising the money. Without fundraising, these field trips and special school memories would be missed.
In a word, fundraising helps children a lot in many ways.
1.The underlined word “inevitable” in the first paragraph means “_______”.
A. 不可能的 B. 不恰当的 C. 不可避免的 D. 不现实的
2.One of the important indications that children are grown up is that __________.
A. children can deal with money
B. children learn to care for others
C. children make a date with friends of the other sex
D. children like to make up
3.The author thinks that fundraising _______.
A. adds to the family’s burden B. wastes the learning time
C. helps to develop the children’s character D. builds up the children’s bodies
4.Which of the following shows the structure of the passage?
CP: Central point P: Point Sp: Sub-point(次要点) C: Conclusion
高三英语阅读理解中等难度题查看答案及解析
Have you ever wondered where the chocolate in your favorite candy bar comes from? Choco-
late comes from the cacao tree, which grows in warm, tropical areas of West Africa, Indonesia, Malaysia, Mexico, and South America. And who eats the delicious chocolate made from the cacao grown in these places? The majority of chocolate is consumed in Europe and North America. This probably sounds like a familiar story-developing countries produce inexpensive raw materials that are manufactured and sold as finished goods in developed countries, and generally, that is what happens with chocolate. Large chocolate companies buy cacao beans at a low price and produce cocoa and chocolate products to sell at a relatively high price.
But the familiar story has a new chapter. Beginning in the 1980s, some consumers learned that cacao farmers were living difficult and uncertain lives. The farmers received money for their crops based on world markets, and the market price for cacao was sometimes so low that farmers received less for their crops than the crops had cost to produce. In response, groups of consumers in Europe and the United States developed "fair trade" organizations to guarantee that farmers of cacao, as well as coffee and tea, would receive fair and consistent prices for their crops.
Fair trade organizations benefit farmers by buying cacao beans or other products from them directly at higher-than-market prices and eliminating(消除)“middle men" such as exporters. Fair trade organizations also encourage farming techniques that are not harmful to the environment or to farm workers. for example, growing cacao without chemical pesticides or fertilizers in the shade of rain forest trees.0ne organization, Equal Exchange, helps farmers set up farming cooperatives in which they can share resources and work on projects such as community schools. Another, Fairtrade Labelling Organizations International(FLO),guarantees that products bearing its label meet standards that improve the lives of growers and producers.
The results of fair trade are a better standard of living for some farmers and nicer chocolate bars made with organically produced cocoa that consumers don't feel guilty about buying. And al- though fair trade chocolate is somewhat more expensive than other chocolate and now makes up only 1% of chocolate sold, the fair trade idea is spreading quickly. You may soon see fair trade chocolate right next to the more famous bars in your favorite store.
1.The underlined word“that”in Paragraph l refers to .
A. the unfair trade between countries
B. the high price of chocolate products
C. the traditional production of raw materials
D. the major consumption of the finished food
2.The organization Equal Exchange aims to .
A. promote chocolate sales
B. offer support to the farmers
C. reduce the cost of growing crops
D. increase the production of chocolate
3.What does the author imply in the last paragraph?
A. There will be more fair trade chocolate ill the future.
B. Fair trade chocolate is not as tasty as other chocolate.
C. Consumers feel guilty about buying fair trade chocolate.
D. There is probably no reason to worry about cacao farmers.
4.The passage mainly talks about .
A. giving tips on how to undertake fair chocolate trade
B. advising people to join in Fair trade organizations
C. encouraging farmers to adopt organic farming
D. informing people of fair trade chocolate

Students can learn how to deal with money by fundraising. Of course, it might seem safer for us to take charge of our children’s earnings from their fundraising before it is turned in to the school.

Dealing with money is important to know about when they are older.
Fundraising helps improve their schools. It is the child’s school. They have to learn there and grow there. Why not let them help in making it a better place? When one of our local schools lacked funding for sports, the students and parents joined hands to raise that money needed. When they succeeded, they felt they accomplished something important.
Fundraising allows for more life experiences for the child. Most fundraising is done for individual classes and clubs. The raised money is used towards things like parties, trips. The children receive the rewards for their hard work at raising the money. Without fundraising, these field trips and special school memories would be missed.
