There is growing concern about food insecurity in the developing world. Rising food prices, weather emergencies and political problems are deepening the struggle for families in many countries.

Three UN agencies have published a report recently, saying high prices are likely to continue. Gregory Barrow, who is with the World Food Program in Rome, says, “If you look at the places where the World Food Program works, particularly in developing countries, you see people who might be spending more than 60 percent of their salary in purchasing food for their families.”

East Africa is suffering its worst drought in years. In Kenya, at least three and a half million people are going hungry, mostly in the north. Yet food is going to waste in central Kenya. Now, farmers there want the government to buy their food and give it to those in need. Farmers say bad roads and lack of transportation make it difficult for them to get their produce to the market.

Mr. Barrow says, “It needs the government to make some arrangements such as providing transport. They can buy it at a good price, then give it to those people instead of asking for food from overseas, which is very bad. When we are throwing away food, they are asking for food from overseas.”

Economists say that imports reduce local food prices, decrease productivity(生产效率) and increase the dependency on other countries. Farmers in Kenya hope the government can pay higher prices for their crops so that they can feed more Kenyans.

1.What is the best title for this passage?

A. Kenya Imports Food from Abroad

B. A World Food Program in Rome.

C. The Poor Suffer from High Food Prices.

D. A Report Published by Three UN Agencies.

2.What do we know about Kenya from the passage?

A. The people in central Kenya are suffering from hunger.

B. At least three and a half million Kenyans lack food.

C. The Kenyan government wants to improve road conditions.

D. People in northern Kenya refuse to ask for food from overseas.

3.What does “they” in the fourth paragraph refer to?

A. The people of northern Kenya.

B. Government officials.

C. The farmers of central Kenya.

D. Kenyan economists.

4.Which of the following statements is TRUE, according to this passage?

A. Gregory Barrow suggests that Kenya make good use of overseas food.

B. People in northern Kenya are suffering the drought less than the central.

C. Economists believe importing food from abroad may cause problems.

D. Kenyan government hopes to buy the native crops at higher prices.

Poor families in some countries spend as much as eighty percent of their money on food. Rising prices in recent months have created the worst food crisis(危机) in more than thirty years. The United Nations World Food Program says high food prices could push one hundred million people into hunger.

Nathan Childs is an expert on rice markets. He notes that the harvest for the latest growing season was the largest on record. But India, Vietnam and others have restricted exports(限制出口) to keep prices down at home and protect supplies.

Thailand’s agriculture minister says his country will never restrict rice exports. He told the Reuters news agency Thursday that Thailand has enough supplies to meet demand at home and for export.

Thailand is the world’s largest rice exporter. Recent signs of an increase in supplies have helped ease record prices for Thai rice. Prices rose last week above one thousand dollars a ton.

Vietnam, the second biggest exporter, has banned(禁止) exports until June. And Vietnamese officials have now warned that non-food traders who buy rice for speculation(投机活动)will be severely punished.

Some experts say speculation is a necessary part of market activity. But the head of the U.N. Environment Program blames it for the high food prices. “We have enough food on this planet today to feed everyone.” Achim Steiner told the Associated Press.

Earlier, a member of the United States Commodity Futures Trading Commission didn’t accept the idea that speculators are the main cause. Bart Chilton blamed reduced harvests and grain supplies and the falling value of the dollar.

U.N. Secretary General Ban Ki-moon called heads of major international agencies to a meeting this week in the Swiss capital, Bern. He says high food prices could harm world trade, economic growth, social progress and political security.

1.What is the main idea of the passage?

A．Vietnam has banned rice exports to other countries.

B．Thailand is the largest rice exporter in the world.

C．Some families are too poor to afford enough food.

D．Rising prices of food have led to the world food crisis.

2.Which country restricted food exports according to the passage?

A. Thailand.    B. Switzerland.    C. Vietnam.    D. The USA.

3.All of the following are the results of rising prices of food EXCEPT ____.

A．the worst food crisis

B．reduced harvests and grain supplies

C．people spending more money on food

D．pushing one hundred million people into hunger

4.What is the reason for the speculation according to the head of the U.N. Environment Program?

A．High food prices.

B．The falling value of the dollar.

C．Enough rice supplies in some countries.

D．Restricted food exports in some countries.

Our risk of cancer rises rapidly as we age．So it makes sense that the elderly should be routinely screened(拍片检查) for new tumors (肿瘤) or doesn’t it?

While such tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly．With the percentage of people over age 65 expected to nearly double by 2050, it s important to weigh the health benefits of screening against the risks and costs of routine testing．

In many cases, screening can lead to additional examinations and operations to remove cancer, which can cause side effects, while the cancers themselves may be slow　　　　 growing and may not cause serious health problems in patients’ remaining years．But the message that everyone must screen for cancer has become so ingrained (根深蒂固的) that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a noisy reaction among doctors, patients and social groups．

It’s hard to uproot deeply　　　　 held beliefs about cancer screening with scientific data．Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment．And clearly, people over age 75 who have other risk factors for cancer, such as a family history or previous personal experience with the disease, should continue to get screened regularly．But for the rest, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy．

A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening—especially considering the explosion of the elderly．

It’s not an easy calculation to make, but one that makes sense for patients．Dr．Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves from medical disputes（争端）．We need to think about the wise use of health care, which means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better．”

1.Routine cancer screening for the elderly people makes sense because ______．

A．it is believed to contribute to a long life

B．it is part of their health care package

C．they are more sensitive about the health

D．they are in greater danger of tumor growth

2.How do some researchers now look at routine cancer screening for the elderly?

A．It adds too much to their medical bills．

B．They are doubtful about its necessity．

C．It helps increase their life expectancy．

D．They think it does more harm than good．

3.What is the traditional view about women screening for breast cancer?

A．It is a must for adult women．

B．It applies to women over 50．

C．It is intended for young women．

D．It doesn’t apply to women over 74．

4.What does the writer say is the general view about health care?

A．Better care, longer life．

B．Prevention is better than cure．

C．Better early than late．

D．The more, the better．
