“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine，newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food and Drug Administration)can require proof under the Food, Drug, and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure(查封)of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings(法律訴訟)，and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
【小題1】It can be inferred that the ads mentioned in the text are            .        .

A．objectiveB．costlyC．unreliableD．illegal
【小題2】Which of the following is TRUE according to the text?
A. The court is in charge of removing dangerous products.
B. New products are more likely to be questionable.
C. The production of a device must be approved by FDA.

For the past year, the World Food Program has operated a project to prevent hunger in twenty-one countries in Africa. In the project, the United Nations agency works with small farmers to grow more and better produce.

The World Food Program buys the produce through local cooperative associations. Then it distributes the products within the country or area. The project works mainly with women. Sheila Sisulu from the World Food Program says the project aims to break a cycle that keeps people hungry. The situation is that farmers have to sell their produce at low prices after harvest, when supplies are greatest. Then they have to pay high prices to buy food for themselves during the "lean season," when supplies are limited.

But when farmers produce more food, they can sell more. And when they produce high-quality food, they can get higher prices. They can also store food for themselves, and have enough money to buy food if they need to during the lean season. Sheila Sisulu says the farmers are now starting to earn profits through the project.

The Food and Agriculture Organization and the International Fund for Agricultural Development help the farmers choose the best seeds and fertilizers. They also advise the farmers on the quality levels that the World Food Program requires to buy their produce.

Two other groups recently launched a separate effort to increase food security in Africa. The groups are the Alliance for a Green Revolution in Africa and the New Partnership for Africa's Development. They say African governments have to increase their investment in agriculture in order to fight problems related to climate change. The groups want the governments to develop programs in seeds, soil health, policy and markets.

Former United Nations chief Kofi Annan is the chairman of AGRA. The group's president, Namanga Ngongi, says many African governments are not meeting a target of spending ten percent of their national budgets on agriculture. But he says investment has risen from four percent of national budgets to probably five and a half percent today.

1. The underlined word “l(fā)ean” in Paragraph 2 probably has the same meaning with ______.

A. He is a tall, lean and handsome boy, liked by many girls.

B. The changes made the company leaner and more competitive.

C. The company recovered well after going through several lean years.

D. The doctor told him that lean meat was healthier for his mother than fatty meat.

2. According to Sheila Sisulu, the project _____.

A. distributes the products within the whole world

B. has benefited few African farmers during the past year

C. enables the African farmers to sell their produce at low prices after harvest

D. can help the farmers to get away from the situation that keeps them hungry

3. The problem of hunger in Africa can possibly be relieved by ______.

A. United Nations chief

B. the World Food Program

C. African governments and farmers

D. the Food and Agriculture Organization

4. Which can be the best title?

A. Hunger, the most serious problem in Africa      

B. Two efforts seek to increase food security in Africa

C. A project to grow more and better produce in Africa

D. More investments in agriculture by African governments

Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.

As we all know, Chinese handwriting has infinite power to express differences of character and cultivation. But we have to admit that traditional handwriting has become a __50__ art, now that kids start using keyboards as soon as they begin school. However, writing things out by hand may be a __51__ way we train our brains, several studies suggest. Many psychologists think that handwriting can make you __52__!

Writing by hand is different from __53__ because it requires using strokes to create a letter, __54__ just selecting the whole letter by touching a key, says Virginia Berninger, a professor of psychology at the University of Washington. These __55__ movements activate large regions of the brain __56__ in thinking, memory, and language. Handwriting helps children learn letters and shapes, improves their composition of ideas, and may also __57__ fine-motor skills development.

A study by Berninger found that in grades two, four, and six, children wrote more words, faster, and expressed more __58__ when writing essays by hand than when typing on a keyboard.

A separate study by researchers at Indiana University found that children who practiced printing by hand had more active__59__than kids who __60__ looked at letters.

It’s not just children who __61__ from writing things out by hand, says a study in the Journal of Cognitive Neuroscience. Adults learning a new language remember its __62__ better if they write them out by hand than if they produce them with a keyboard.

As more people __63__ their days on the computer, says neuroscientist P. Murali Doraiswamy of Duke University, “__64__ people in handwriting skills could be a useful cognitive exercise.”

科目：高中英語(yǔ) 來(lái)源：2009年高考試題（浙江卷）解析版 題型：閱讀理解

 

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants produce volatile compounds, chemicals that easily change from a liquid to a gas .A. flower’s sweet smell, for example, comes from volatile compounds that the plant produces to attract insects such as bugs and bees.

Plants can also detect volatile compounds produced by other plants. A. tree under attack by hungry insects, for instance, may give off volatile compounds that let other trees know about the attack, In response, the other trees may send off chemicals to keep the bugs away- or even chemicals that attract the bugs’ natural enemies.

Now scientists have created a quick way to understand what plants are saying: a chemical sensor（傳感器） called an electronic nose. The “e-nose” can tell compounds that crop plants make when they’re attacked. Scientists say the e-nose could help quickly detest whether plants are being eaten by insects, But today the only way to detect such insects is to visually inspect individual plants. This is a challenging task for managers of greenhouses, enclosed gardens that can house thousands of plants.

The research team worked with an e-nose that recognizes volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds. Based on these interactions, the e-nose gives off electronic signals that the scientists analyze using computer software.

To test the nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all common greenhouse crops. Then the scientists collected samples of air around damaged leaves from each type of crop. These plants had been damaged by insects, or by scientists who made holes in the leaves with a hole punch （打孔器）.

The e-nose, it turns out, could identify healthy cucumber, pepper and tomato plants based on the volatile compounds they produce. It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage – by insects or with a hole punch – had been done to the tomato leaves.

With some fine tuning, a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A. device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareve, a biochemist at Purdue University in West Lafayette, Ind. who studies smells of flowers and plants. Hopefully, scientists believe, the device could bring large benefits to greenhouse managers in the near future.

1.We learn from the text that plants communicate with each other by______.

A. making some sounds    B. waving their leaves

C. producing some chemicals D. sending out electronic signals

2.What did the scientists do to find out if the e-nose worked?

A. They presented it with all common crops..

B. They fixed 13 sensors inside the device.

C. They collected different damaged leaves.

D. They made tests on damaged and healthy leaves.

3.According to the writer, the most amazing thing about the e –nose is that it can ______.

A. pick out ripe fruits

B. spot the insects quickly

C. distinguish different damages to the leaves

D. recognize unhealthy tomato leaves

4.We can infer from the last paragraph that the e-nose_____.

A. is unable to tell the smell of flowers

B. is not yet used in greenhouses

C. is designed by scientists at Purdue

D. is helpful in killing harmful insects
