About ten men in every hundred have the trouble of color blindness in some way. Women are luckier, only about one in two hundred is affected（感染）in this matter. Perhaps, after all ,it is safer to be driven by a woman.
There are different kinds of color blindness. For example, a man cannot see deep red. He may think that red, orange and yellow are all shades (影子) of  green. Sometimes a person can’t tell the difference between blue and green. Only a few unlucky men may see everything in shades of green— a strange world indeed.
Color blindness in human beings is a different thing to explain. In only one eye there are millions of very small things called “cones（锥状细胞）” . These help us to see in the bright light and to tell differences between colors. These are also millions of “rods“（杆状细胞），but these are used for seeing when it is nearly dark. They show us shapes but not colors.
Some insects have favorite colors. Mosquitoes(蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky. With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of the rods we can see shapes at night.
【小题1】“Color blindness” means           in Chinese.
A. 盲目        B. 无色      C 色盲    D 讨厌颜色

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.

A. 2.4 dollars.                                        B. 3 dollars.

C. 3.6 dollars.                                         D. 3.9 dollars.

4.Why is the meat price lower than before?

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.

What are you going to do if you are in a burning house？ How will you escape？ Do you know how to save yourself？ Please read the following passage.

   Escaping a fire is a serious matter. Knowing what to do during a fire can save you life. It is important to know the ways you can use and show them to everyone in the family， such as stairways and fire escapes， but not lifts.

　　From the lower floors of the buildings， escaping through windows is possible， learn the best way of leaving by windows with the least chance of serious injury.

　　The second floor window is usually not very high from the ground. An average person， hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of an average man. Of course， it is safer to jump a short way than to stay in a burning building.

　　Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may leaked（渗） into the room.

　　On a second or third floor， the best windows for escape are those that open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement（水泥） might end in injury. Bushes（灌木丛） and grass can help to break a fall.
