Believe it or not, optical illusion(错觉) can cut highway crashes.
Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent strips, called chevrons（人字形标志）, painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.
Now the American Automobile Association Foundations For Traffic Safety in Washington D.C. is planning to repeat Japan’s success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.
Excessive（过分） speed plays a major role in as much as one fifty of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards(危险) are the greatest-curves, exit slopes, traffic circles, and bridges.
Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars.
Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane（车道） appear to be narrower. The result is a longer lasting reduction of highway speed and the number of traffic accidents.
The passage mainly discusses________.

A．a new way of highway speed control

2010 was a good year for American farmers. They earned about eighty-two billion dollars. That is almost one-third more than that they earned last year. And it is twenty-six percent higher than the ten-year average. Values for grain and oilseed crops are up about three percent from last year. The value of animal production is up by almost seven percent.
In 2011, farm exports are expected to break the all-time high set in 2008.The Agriculture Department says exports in 2011 could top one hundred and twenty-six billion dollars. The largest buyer of agricultural products is expected to be Canada. But farm exports to China are predicted to come within five hundred million dollars of Canadian purchases. Secretary Vilsack says countries in Southeast Asia and the Middle East are also buying more from American farmers.
Poor growing conditions overseas played an important part in higher prices for American crops in 2010.Charlotte Hebe brand is chief executive of the International Food and Agricultural Trade Policy Council in Washington. She said drought(干旱)conditions had a big effect over the summer. She said,“There were horrible weather problems, not just in Russia but also in some of the other former Soviet Union countries.”
Wheat prices rose after Russia stopped wheat exports,although Russia later eased the ban(禁令).“Wheat used to be America’s top crop. What’s interesting,though,is that wheat production has actually become less over the past few years because corn has become the most popular crop,”said economist Charlotte Hebebrand.
Corn is mostly fed to animals. But Miss Hebebrand said with the recent increase in wheat prices, American farmers might plant more wheat again. Corn and wheat are the two largest crops supported by the government.

A．planted less corn	B．planted morn crops

B． Russia was not the country most affected by drought in 2010

C． Weather problems helped raise prices for American crops in 2010

D． American crops were the most expensive around the world in 2010

We can infer that in the past few years American farmers——

A． reduced crop exports

According to what Miss Hebebrand said, we know American farmers will ——

A．stop feeding corn to animals

In America, when people say “man’s best friend”, they don’t mean another person. Instead, they are talking about a lovely animal：A dog! These words show the friendship between people and animals. Dogs and other pets can give happiness to people’s lives. Some people think of their pets as their children. A few even leave all their money to their pets when they die!
Animals can help people, too. Dogs can be taught to become the “eyes”for a blind person or “ears”for a deaf people. Scientists have found that pets help people live longer! They make people happier, too. Because of that, animals are brought into hospitals for “visit”.
Americans hold “Be---Kind-to-Animals Week”in the first week of May.
Pets shows are held during the week. Even if you don’t live in America, you, too, can do this. How? First, think about how animals make your life richer. If you have a pet, take more time this week to play with it. Remember to give it delicious food. Also, be sure to keep your pet from those unwanted babies.
If you don’t have a pet, be kind to animals around you. For example, if you see a street dog, don’t kick(踢)it or throw things at it. Instead, just leave it alone, or beter yet, make friends with it. If others around you do bad things to an animal, try to shop them. As people, we must protect animals who can’t speak for themselves.

That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theatre. With opening night only a week ago, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.
As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers (抢劫犯). Very few people were still out except a few sad-looking homeless people under blankets.
About a block from my apartment (公寓房间), I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.
Suddenly I wasn’t cold or tired anymore. I ran out of the door and back to where I’d heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.
Just as I was about to give up the search, I heard the garbage truck (垃圾车) pull up to the sidewalk next to me. When a voice called from the inside, “ Alisa Camacho?” I thought I was dreaming. How could this man know my name? the door opened, and out jumped a small red-haired man with an amused look in his eye. “Is this what you’re looking for?” he asked, holding up a small square shape.
It was nearly 3 A.M. by the time I got into bed. I wouldn’t get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn’t be a bad place as long as people were wiling to help each other.

Research by sociologists Scott Coltrance Michele Adams looked at national survey data and found that when men increase their share of housework and childcare, their children are happier, healthier and do better at school．What’s more, when school-aged children do housework with their fathers, they get along better with their peers and have more friends．And they show more positive behaviors than if they do the same work with their mothers．“Because fewer men do housework than women,” said Adams, “when they share the work，it has more influence on children．” Fathers model “co-operative family partnerships”．
When men share housework and childcare, it turns out, their partners are happier．Wives of egalitarian（主张人人平等的）husbands, regardless of class, report the highest levels of marital（婚姻的）satisfaction and lowest rates of depression，and are less likely to see therapists（治疗专家）．They are also more likely to stay fit, since they probably have more time on their hands．
And the benefits for men are even greater．Men who share housework and childcare are healthier--physically and psychologically．They smoke less, drink less, and take recreational drugs less often．They are more likely to stay in shape and more likely to go to doctors for routine screenings, but less likely to use emergency rooms or miss work due to illness．
In both Europe and the United States，Dad is becoming the “fun parent”．He takes the kids to the park and plays soccer with the kids; she stays home．“What a great time we had with Dad!” the kids announce as they burst through the kitchen door to a lunch mum prepared．
We can infer from the first paragraph that ．

A．fathers usually have greater influence on their children

B．it's better for school-aged children to do housework with their mothers

C．few boys would like to do housework

D．children benefit more from doing housework with their fathers
