【题目】Two American scientists told the people in industrial nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.

The scientists say that the human body has changed very little since human first appeared on earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中风 ) are examples of such diseases.

Scientists noted that early stone-age people used very little alcohol ( 酒精 ) or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and life today.

Stone Age people hunted wild animals for their meat, which had much less fat than farm animals. They also ate a lot of fresh wild vegetables, and fruits. They did not use milk and other dairy products, and they made a very little use of grains. But today, we eat a large amount of dairy products and grain foods. We eat six times more salt than stone-age people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less Vitamin C.

People today probably do not want to live as people thousands of years ago did, but scientists say that we would be much healthier if we ate as those ancient people did, cutting the amount of fatty, salty and sweet foods.

【题目】Undoubtedly there are a few positive characters who are able to “rise above” their environment, who are able to impress the people with whom they come in contact in spite of their clothes.

Sometimes we read of some learned woman, who has “made good in her profession,” who says that she has not looked in a mirror for years; but such a woman is a rare exception, and one is not safe in gambling with one’s chances of success by following her. It is not the positive characters with whom we are concerned, however, for they are few and somehow manage to take care of themselves. The vast majority of the race are not so blessed, and we need to observe but little to realize that with them the reaction of clothes is an important factor.

School girls should know that clothes may make a career; happiness and leadership in all the years of high school and college life may be affected by the story a Freshman’s clothes tell. Many a girl with a keen mind, who has a natural disregard for clothes, perhaps, or who has not been trained in the appreciation of beauty in clothes, has lost her opportunities for leadership and self-expression which by right her brain power should have given her.

One of the mental capacities which we all exercise and yet exercise most unconsciously is that of passing judgment on the people we meet. In a majority of cases the judgment is superficial and inaccurate; but the estimate is made. Some people may not get their final judgment till they hear one talk and will judge one by the tone of voice and by what is said as the true index; but the vast majority will form an opinion based largely, if not entirely, on appearance. One tells the world daily of one’s ideals, ambitions or good breeding through dress; and it is told so plainly that “he who runs may read” and, perhaps, he who reads may run.

A. care about their appearances

B. understand the art of dressing themselves

C. can catch others’ attention by dressing plainly

D. are able to dress properly without professional directions

A. Book writers B. Women

C. Men D. Fashion designers

3】The author thinks it is _______ for most of us to judge the people we meet by what they wear.

A. natural B. foolish C. surprising D. necessary

4】Which of the following can be the best title?

A. Rise Above Your Environment

B. He Who Runs May Read

C. Dress to Impress

D. Art of Dressing

【题目】Here’s one number to keep in mind during your next cell phone conversation: 50. A new experiment shows that spending 50 minutes with an active phone pressed up to the ear increases activity in the brain. This brain activity probably doesn't make you smarter. When cell phones are on, they emit (发出) energy in the form of radiation that could be harmful, especially after years of cell phone usage. Scientists don't know yet whether cell phones are bad for the brain. Studies like this one are attempting to find it out.

The 47 participants in the experiment may have looked a little strange. Each one had two Samsung cell phones attached to his or her head — one on each ear. The phone on the left ear was off. The phone on the right ear played a message for 50 minutes, but the participants couldn't hear it because the sound was off.

With this set-up, the scientists could be sure they were studying brain activity from the phone itself, and not brain activity due to listening and talking during a conversation. After 50 minutes with two phones strapped to their heads, the participants were given PET scans.

The PET scan showed that the left side (the side with the phone turned off) of each participant's brain hadn't changed during the experiment. The right side of the brain, however, had used more glucose, which is a type of sugar that provides fuel to brain cells. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that the brain cells there were active ― even without the person hearing anything. That activity, the scientists say, was probably caused by radiation from the phone.

Henry Lai, who works at the University of Washington in Seattle, is uncomfortable with the data related to cell phones. Holding a cell phone to your ear during a conversation is “not really safe,” Lai told Science News. Lai is a bioengineer at the University of Washington in Seattle. He wrote an article about the new study for a journal, but he did not work on the study. Bioengineers bring together ideas from engineering and biology.

For those who don't want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely. You can have short and sweet conversations, use a speakerphone or keep the phone away from your head.

1Which of the following statement is true?

A. Scientists are sure that cell phones are bad for the brain.

B. In the experiment, the left side of the brain used more glucose.

C. Radiation from the phone probably causes the change in the brain.

D. Henry Lai wrote a lot of articles about this new study.

2Why weren’t the participants allowed to have a conversation on the phone during the experiment?

A. Because the scientists want to be sure of the accuracy of the experiment.

B. Because they really looked strange and no one wanted to talk to others.

C. Because they were given PET scans and they lost the ability to talk.

D. Because that would be too noisy and bad for the experiment.

3What is glucose?

A. A type of sugar that provides vitamin to brain cells.

B. Something that the right side of the brain used.

C. A type of sugar that gives energy to brain cells.

D. Something that makes a human excited.
