you are always wearing the glasses? Yes, many of us will feel tired when we wear the glasses for a long
time. So a new kind of glasses is more and more popular now. And millions of people like it very much. It
is contact lenses (隐形眼镜).
     Millions of people use the contact lenses. For anyone who doesn't mind sticking his fingers in his eyes,

You might have noticed that the cost of food has gone up.In fact the price of wheat and rice has nearly doubled in the past few years.It’s thought that right now，850 million people—that’s more than 10 times the population of the UK—are short of food because it’s too expensive or there’s not enough of it.

The price of basic food such as wheat and corn has stayed the same for quite a long time，about 30 years.But as the world’s population is getting bigger，there’s more pressure to feed more people，plus there’s less land and water to go round.

Another reason is climate（气候）change.Droughts and floods make it hard to grow crops like rice and grain.The price of oil has gone up and that makes it more expensive for farmers to run their tractors and to transport the food they make.And lots of fields are being used to grow crops to make other things that can’t be eaten—which is bad news for hungry people.

The main losers are poor people who live in cities in poor countries，who are facing higher prices for food.Some people are doing well out of the food crisis（危机） though.Farmers in rich countries like the US，Canada and Australia are getting record prices for their harvests.

World leaders are meeting in the Italian capital Rome to talk about the problem of rising food prices.Some countries are helping out with the cost of foods and international aid agencies have called for more money for food production in poor countries.

B．They have to save a lot of money.

The United States is suffering its worst drought (干旱) in almost sixty years. The National Climatic Data Center also says high temperatures in June added to the warmest twelve-month period on record. Record-keeping began in 1895. The drought map showed that conditions improved in the Southeast in June compared to May. But the drought is expected to continue in large parts of the country. Last week, Agriculture Secretary Tom Vilsack met with President Obama. Mr Vilsack says the drought has seriously influenced some crops, such as corn and soybeans (大豆). And the United States is the world's leading producer.

The drought has made prices of com and soybeans increase. Both of them are used in food production and for animal feed. Last week the United Nations Food and Agriculture Organization reported that corn and wheat prices increased by 20% over the past three weeks.

In the United States, farmers may quickly reduce the size of their animals rather than pay higher feed prices to keep them. That increased supply of meat would reduce meat prices in the short term. But those prices could increase in several months.

Mr Vilsack says the effect of the drought is hard to predict(预测). Some areas are getting rain, and drought-resistant (抗旱的) seeds have helped crops grow well in some areas.

1.We can know the drought record of the USA has been kept for ________years of the USA up to now.

A. 97 B. 207

C. 221 D. 117

2.Which of the following American presidents met with Tom Vilsack?

A. George Washington. B. Abraham lincon.

C. George Bush. D. Barack Obama.

3. If the price of a kilo of corn was 3 dollars last December, how much is a kilo of corn now?

A. 2.4 dollars. B. 3 dollars.

C. 3.6 dollars. D. 3.9 dollars.

4.Why is the meat price lower than before?

A. Because there are more and more animals.

B. Because farmers kill them to save their food.

C. Because people don't like eating meat now.

D. Because the government (政府) asks the meat price lower.

5.What is the best title for the passage?

A. US faces the worst drought in almost sixty years.

B. Take action to help the USA.

C. What does the country do in the drought areas?

D. President Obama meets with Agriculture Secretary.
