The food we eat seems to have great effects on our health. Although science has made great steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to diet as well. Different cultures are subject to certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery.
In 1945, government researchers realized that nitrates(硝酸盐) and nitrites(亚硝酸盐), commonly used to keep color in meats, and other food additives, caused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels(标签) of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to cows and chick and because of this, penicillin has been found in the milk of treated cows.
Sometimes similar drugs are given to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although the FDA has tried repeatedly to control these, the practices continue.How has science done a bad service to mankind?

B.It has caused a lack of information about the value of food. |
C.Some harmful materials have been added to our food. |
D.Scientists have made food more expensive to eat. |
What are nitrates used for?
A.They help process packaged food. |
B.They keep the color in meats. |

uChildren start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’ve finished with your lists, do you have questions of your own about science?”
After a long pause, a boy raised his hand,” Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?”
This began a set of questions that lasted nearly two hours.
Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合逻辑的),complete and creative answers.
Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying, “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.
Never push a child to “Think”. It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.
Lastly, show doesn’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates (蒸发),set a pot of water to boil and let them watch the water level drop.

President Barack Obama has apologized for a gaffe (失言) in which he described his bowling skills as akin to participants in the Special Olympics, a sports program for people with intellectual disabilities.
Obama made the mistake during an interview on Thursday night on “The Tonight Show” with host Jay Leno, the first time a sitting U.S. president had been on the show.
Talking about living in the White House, Obama said he had been practicing his bowling in the home’s bowling alley and had scored a 129 out of a possible 300.
It was an improvement on the embarrassing 37 he had rolled during a stop on the presidential campaign trail a year ago. “It’s like—it was like Special Olympics or something,” Obama said.
The Special Olympics is a global nonprofit organization serving some 200 million people with intellectual disabilities, with a presence in nearly 200 countries worldwide.
Soon after the Jay Leno interview, Obama telephoned Special Olympics chairman Tim Shriver to apologize.
Shriver told ABC’s “Good Morning America” television show that Obama had apologized “in a way that I think was very moving” and that he said “he did not intend to humiliate (羞辱) the population, didn’t want to embarrass or give anybody any more reason for pain or kind of suffering.”
Shriver said people should gain a lesson from the incident.
“I think it’s important to see that words hurt. Words do matter. And these words in some respect, can be seen as humiliating or a put-down to people with special needs, do cause pain. And they do result in stereotypes,” Shriver said.
White House spokesman Bill Burton said Obama “made an offhand remark making fun of his own bowling that was in no way intended to look down upon the Special Olympics.”
“He thinks that the Special Olympics are a wonderful program that gives an opportunity to shine to people with disabilities from around the world,” Burton said.

For the most part, schools are designed to produce people who fit into society, not people who set out to change it. However, schools, particularly universities, may not only spread culture; they may add to the cultural heritage(遗产). Today American society places a good deal of emphasis on the development of new knowledge, especially in the physical and biological sciences , medicine, and engineering. In the recent years, the nation’s leading universities have increasingly become research centers.
An emphasis(强调)on research has led universities to judge professors not by abilities as teachers, but as researcher. promotions(提升), salary increases , and other benefits have long been dependent on research and publication. However, the most important is no longer publishing. To be successful these days, professors have to bring in money provided by government and private industry. Critics claim that academic(学术) success is most likely to come to those who have learned to“ignore”their teaching duties to pursue research activities. Defenders say that even when students themselves are not involved in research projects they benefit from such an emphasis on research.
Major research universities like the Massachustts Institute of Technology have also cooperated with industrial companies to develop technology and products with commercial potential(潜能).With university-industry ties continuing to grow, debate(辩论)has increased about the consequences for basic science, academic openness, the control of information, the direction of research, and the influence on students.
1. According to the passage, which of the following is NOT emphasized by today’s American society?
A. Physical science. B. Biological science.
C. Engineering.D. Computer science.
2. In the present standard, a successful professor is one who can____.
A. teach well
B. get financial support for research
C. get the highest salary
D. have many publications
3. Supporters of the present emphasis on research argue that_____.
A. it involves more students in it.
B. it does good to students anyway.
C. it has a direct good effect on teaching
D. it earns a lot of money for a university
4. The author seems to be_____ the move of emphasis to research.
A. totally againstB. sorry to see C. in favor of D. neutral (中立) about
Electricity shortage leaves Afghanistan in the dark. Electricity is in short supply in the Middle Eastern Nation of Afghanistan. Only 6 percent of the country’s residents have electric power, according to the Asian Development Bank, an organization that works to reduce poverty.
Some residents in Kabul received only 3 hours of electricity a day last fall. Others received none. Kabul is the capital of Afghanistan. “It’s dark everywhere,” says city resident Gul Hussein. “Some of our neighbours are using candles.”
Experts say water shortage is partly to blame. Water is used to make electricity. In Kabul, power becomes scarce in midsummer, when the region’s hydroelectric(水力发电的) dams dry up. Hydroelectricity is made by the force of falling water.
Kabul’s growing population is also a cause. Since the late 1990s, the city’s population has jumped from less than 1 million to more than 4 million people. Now even more electricity is needed.
Despite receiving millions of dollars in international aid, the country’s electricity shortages continue. Still, Afghans hope for a solution. One plan is to import, or bring in, power from the nearby country Uzbekistan. Afghan officials also spoke with U.S. president about the nation’s need to make its own electricity.
“ Life takes power,” says Jan Agha, a worker from Kabul. “If you have electricity, life is good; but if there’s no electricity, you go around like a blind man.”
1.One reason for electricity shortage is _________
A. the lack of international aid
B. the shortage of hydroelectric dams
C. the increase of population
D. the low temperature in midsummer
2. Which of the following will probably a solution for the problem of electricity shortage?
A. To build more hydroelectric dams.
B. To advise people to use less electricity.
C. To buy electricity from America.
D. To produce electricity on its own.
3. What does the underlined word “scarce” mean in paragraph 3?
A. not normal B. not little C. not effective D. not enough
4. Which one should be the best title for the passage?
A. Water Shortage in Afghanistan B. Population Lead to Lack of Electricity
C. Electricity Shortage in Afghanistan D. Help Needed in Afghanistan
Remembering names is an important social skill.Here are some ways to master it.
Recite and repeat in conversation.
When you hear a person’s name,repeat it.Immediately say it to yourself several times without moving your lips.You could also repeat the name in a way that does not sound forced or artificial.
Ask the other person to recite and repeat.
You can let other people help you remember their names.After you’ve been introduced to someone,ask that person to spell the name and pronounce it correctly for you.Most people will be pleased by the effort you’re making to learn their names.
Admit you don’t know.
Admitting that you can’t remember someone’s name can actually make people relaxed.Most of them will feel sympathy if you say.“I’m working to remember names better.Yours is right on the tip of my tongue.What is it again?”
Use associations.
Link each person you meet with one thing you find interesting or unusual.For example,you could make a mental note: "Vicki Cheng -- tall, black hair. " To reinforce you’re your associations, write them on a small card as soon as possible.
Limit the number of new names you learn at one time.
When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.
Go early.
Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. That's fewer names for you to remember. And as more people arrive, you can hear them being introduced to others -- an automatic review for you.
1. How will most people feel when you try hard to remember their names?
A. They will be moved. B. They will be annoyed.
