When we Americans shop at the grocery stores today, we don’t seem to be surprised at the sight of strawberries in the winter or perfect tomatoes from Holland. In the space of a generation, we’ve become accustomed to eating food that’s never grown roots in local soil. In fact, most produce(农产品) grown in the United States travels an average of 1,500 miles before it gets sold.
Trucking, shipping and flying in food from around the country and the globe has a very bad effect on the environment and on public health. Take grapes for example. Every year, nearly 270 million pounds of grapes arrive in California, most of them shipped from Chile to the Port of Los Angeles. Their 5,900-mile journey in cargo ships and trucks gives off 7,000 tons of global warming pollution each year, and enough air pollution to cause dozens of asthma(哮喘) attacks and hundreds of missed school clays in California.
The way we eat has a great influence on the health of the planet. By choosing to eat lower on the food chain, and focusing on local and organic(有机的) produce, we can reduce global warming and air pollution, avoid poisonous chemicals, support local farmers and enjoy fresh, tasty food.
People are rediscovering the benefits of buying local food. How your food is grown, stored, transported, processed and cooked can all influence how it affects climate and the environment. Transportation-related influences are particularly important for imported foods. NRDC calculated the transportation influences of importing fresh produce and wine widely consumed in California. They directly compared the climate and air quality influenced by importing these foods instead of growing and consuming them in California. Their analysis shows that—all else being equal—locally grown foods are a better choice.
72. From the passage we can learn that most produce sold at the grocery stores in the US     .
A. is grown by local farmers                          B. is from foreign countries
C. comes from far away                              D. is out of season

A. It pollutes the foods during the transportation.
B. It makes the cost of the foods much higher.
C. It makes the foods less fresh and tasteless.
D. It causes air pollution and global warming.
74. Which of the following may have a bad effect on the health of the planet?
A. Eating higher on the food chain.                 B. Eating locally grown foods.
C. Eating more organic produce.                   D. Eating fresh and tasty foods.
75. The main purpose of the passage is         .
A. to help the local farmers grow and sell their produce
B. to tell people that imported foods are less healthy

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet”when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet”quickly goes away. When other ants detect the“dead”chemical without the“not dead yet”chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the“Wait—I'm not dead yet”chemical, other ants left the treated ant alone. Choe believes this behavior shows that the“not dead yet”chemical overrides the“dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

When the six very best students from different cities in Guangdong province all together chose universities in Hong Kong; when the very best student of Beijing picked up HK University while giving up the nearby Peking or Tsinghua University; when the highest enrollment(录取) rate of Hong Kong Science and Industry University reached 48:1, it’s the high time to ask where the real education heaven for students in China is.
Years ago, the answer certainly would be “Peking or Tsinghua University”. But now no one could give the exact reaction without hesitation. The only sure thing is that HK universities have gradually showed an unusual attraction to a great many mainland students.
It’s no doubt to call this HK craze(狂热), which is even out of the expectation of those HK universities themselves.
How can HK universities shake the steady foundations of Peking and Tsinghua and attract so many mainland students?
First, Hong Kong universities offer large-amount scholarship, especially for the top students who can receive the sum scholarship as much as 400 000 HK dollars. Since higher education has become a kind of heavy burden of many families, it’s easy to understand why the reaction to the generous offering of HK universities is great.
Second, most HK universities receive professors and students from all over the world and carry out bilingual (双语)education. This kind of excellent language atmosphere is another attraction for mainland students.
Furthermore, university students in Hong Kong have a better chance to study abroad as exchange students.
Can mainland top universities like Peking or Tsinghua University calm as before when facing the unexpected competition from HK? Will they take relevant measures to win back the top students who once help them set the worldwide reputation? Time will explain it.
The fierce competition brought by HK universities can be a good thing for an entire improvement of education in China. After the awakening and action-taking of mainland universities, they can perform better together with HK universities.
At least, it reminded the mainland universities the tuition fees(学费)are among students’ top concern when they are choosing universities. It’s time to move.
72.What is the passage mainly talking about?
A.Some thoughts brought by the enrollment of HK universities.
B.Higher education in Hong Kong.
C.The competition between HK University and Peking University.
D.The fall of mainland universities.
73.Top students from mainland apply for HK universities because________.
A.many students now would love to study abroad to get a better experience
B.they concern only about the tuition fees when shoosing universities
C.HK Universities offer higher scholarship, better environment and more opportunities for their further study
D.Peking university has lost its worldwide reputation
74.What is the author’s attitude toward the competition brought by HK universities?
A.The government should take relevant measures to stop this unfair competition
B.Mainland universities had better lower their tuition fees and win back the top students.
C.Universities both in mainland and in HK would get an entire improvement during the competition.
D.It may probably cause a complete loss to both sides in the end.
75.From the passage we can see HK universities________.
didn’t mean to enroll top students from mainland
B.didn’t expect their enrollment of mainland students would be so popular
C.have strict enrollment rules and only 1out of 48 students can get the chance to study there
D.are proud of their teaching staff and facilities

When I was growing up, 16 was always a magical age, a symbol of maturity, responsibility and of course more independence and freedom.  I sat through the hours of Driver’s Ed classes eager to get out on the road. I couldn’t wait to get my driver’s license.
But it’s a different story for today’s teens. In January, the U.S. Department Transportation released 2012 data that showed only 30.7 percent of U.S. teens got their license at age 16, Twenty years before, that number was almost 45 percent.
There are numbers of reasons for the fall – off. The growing responsibilities like paying for insurance and high gas prices discourage teens from getting behind the wheel. Plus, many teens today are so busy with homework, endless hours of activities and part-time jobs, that finding the time for Driver’s Ed classes may be more difficult that ever.
In addition, many states have raised the driving age, or restricted when teens can drive and who they can have in the car. Parents may also be making their own personal restrictions until they feel their teens are responsible enough to drive safely.
Driving is part of the American culture, but it’s not the central focus like it was 25 years ago. They have so many other things to do now. One of the more interesting factors delaying teens driving might be the change of their social life. Today, teens need to look no further than Face book or other social networking sites to connect with their friends. There is simply less need, maybe less desire, to be able to grab the keys and go.
Michelle Wei got her license as a senior in high school because her digital social life made it easy no to drive. “If I couldn’t get a ride to see my friend who lives a town over,” the 19-year-old said, “I could talk on IM or Skype.”
Research has shown that these online relationships can lead to higher quality friendships, so it isn’t necessarily a bad thing. However, it’s important to find a balance. If old face-to-face friendships are good, why not drive to find them?
【小题1】We can infer from the first paragraph that         .

A.Driver’s Ed classes allowed teens to know what maturity was
B.getting a driving license at 16 was a must for American teens
C.16 was considered an age when one could get his driver’s license
D.teens could drive on the road without taking Driver’s Ed classes
【小题2】What does the passage mainly talk about?
A.Desire to drive on the road declines among American teens.
B.Getting a license costs much more than ever before.
C.Social networking sites are changing the life of American teens.
D.American teens are becoming more responsible than ever.
【小题3】Michelle’s Wei’s example is used to explain ________.
A.why American teens are crazy about digital social life
B.what social networking websites are bringing to American teens
C.to what degree the Internet is affecting the American car culture
D.what the Internet does to help teens to get a driving license
【小题4】The last paragraph is reminding the readers that        .
A.the Internet h as a bad effect on the teen’s social life
B.teens should keep a balance in choosing their lifestyle
C.actual contacts can be replaced by talking on line
D.face-to-face friendship is always the best choice
