Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experi­ment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention to class.
Opposite to what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
【小题1】During the test, those who were tested were given ________.

【小题3】The passage mentions that many people believe that if you don't eat breakfast, you will ____.

A．lose weight

B．not lose weight

C．be healthier

D．gain a lot of weight

【小题4】Which of the following is not true according to the passage?

A．Poor breakfast affects those who work with brains.

D．Eating less in lunch and supper may help to lose weight.

In the United States, 30 percent of the people have a “weight problem”. To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat.
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
【小题1】Nowadays many Americans have the problem that ______.

A．they are too slim	B．they work too hard
C．they are too fat	D．they lose too much body fat

【小题2】According to the passage, how many people in 900 Americans have a “weight problem”?

A．150.

B．300.

C．600.

D．270.

【小题3】Is there any scientific evidence to support the idea that eating too much is the cause of a “weight problem”?

A．Yes, there is plenty of evidence.

B．Of course, there is some evidence to support this.

C．There is hardly any scientific evidence to support this.

D．We are not sure.

【小题4】The Americans in 1910 ________.

A．ate more food and had more physical activities

B．ate less food but had more physical activities

C．ate less food and had less physical activities

D．had more problems

A purple tomato genetically engineered to contain nutrients more commonly seen in dark berries helped cancer in mice, British researchers said on Sunday. The finding, published in the journal Nature Biotechnology, bolsters the idea that plants can be genetically modified(changed) to make people healthier.

Cancer-prone mice fed the modified fruit lived significantly longer than animals fed a standard diet with and without regular tomatoes, Cathie Martin and colleagues at

the government-funded John Innes Center in Britain reported. “The effect was much bigger than we had expected.” said Martin, a plant biologist.

The study focused on anthocyanins，a type of antioxidant found in berries such as blackberries and blackcurrants that have been shown to lower risk of cancer, heart diseases and some neurological diseases. While an easy way to improve health, many people don’t eat enough of these fruits, the researchers said. Using genes from the snapdragon flower, the researchers discovered they could get the tomatoes to make anthocyanins---- turning the tomato purple in the process.

Mice genetically engineered to develop cancer lived an average of 182 days when they were fed the purple tomatoes, compared to 142 days for animals on the standard diet. “It is greatly encouraging to believe that by changing diet, or specific components in the diet. You can improve health in animals and possibly humans.” Martin said in a telephone interview.

The researchers warned that trials in humans are a long way off and the next step is to investigate( look into) how the antioxidants actually affect the tumors to promote better health. But the findings do support the formal research suggesting that people can significantly improve their health by making simple changes to the daily diet, other researchers said.

“It’s exciting to see new techniques that could potentially make healthy foods even better for us.” said Doctor Lara Bennett, science information office at Cancer Research UK. “ But it is too early to say whether anthocyanins obtained through diet could help to reduce the risk of cancer.”

Dr．Sylvia Earle wants you to stop eating fish．It's not because fish are endangered，though wild fish stocks in many oceans are very low．It's not because they're bad for you, though fishin many areas are exposed to poisonous substances in the water．It's because they're smart．

    "Fish are sensitive, they have personalities’，says the marine biologist．For Earle, eating afish would be like eating a dog or a cat．“I would never eat anyone I know personally.”

    There's a lot more to fish than meets the eye: they talk to each other, they like to betouched, and they engage in behavior that can seem very human．They can remember thingsand learn from experience．Earle and a growing number of animal rights activists see these asstrong arguments against eating fish altogether．

    The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket．“While it may seem obvious that fish are able to feel pain, likeevery other animal, some people think of fish as swimming vegetables，” says Dr. Lynne Sneddon. “Really，it's kind of a moral question．Is the enjoyment you get from fishing （oreating fish） more important than the pain of the fish?”

    Fishermen and （fried） fish lovers are doubtful．"I've never seen a smart fish," says Marie Swaringen as she finishes off a plate of fish at a Seattle seafood restaurant．“If they were verysmart, they wouldn't get caught．"

    “For years, everyone's been telling us to eat fish because it's so good for us，” says another diner．‘‘Now I've got to feel guilty while I'm eating my fish? What are they going to think of next? Don't eat salad because cucumbers have feelings?"

Dr．Sylvia Earle discourage people from eating fish because    ．

    A．there are not that many wild fish in the ocean

    B．fish actually are sensitive and have personalities

    C．some ocean fish contain poisonous substances

    D．fish are like dogs or cats that people know personally

We can infer from the passage that      ．

    A．all people don't agree with the idea to stop eating fish

    B．people will be persuaded not to eat fish in the future

    C．stopping eating fish will lead to people's not eating vegetables

    D．we shouldn't care too much about the feeling of fish

By saying "There's a lot more to fish than meets the eye, " the writer means  ．

    A．there are far more fish than other animals in the world

    B．there are more fish in the world than people can see

    C．people can see more fish if they pay more attention

    D．fish are not that simple as they appear to people's eyes

What is the writer's attitude towards people eating fish?

    A．Neutral．    B．Indifferent．    C．Approving．  D．Opposed．

―Correct ____ is important.

―I agree. I don’t eat sweets now, for I’m on a _____.

A. diet; diet      B. food; food             C. diet; food             D. food; diet
