第1题

In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch TV.

Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.

Studies show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting fact:

The more the man ran, the greater loss of body fat.

The more they ran, the greater their increase in food intake.

Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

1、What kind of physical problem do many adult Americans have?____

A、They are too slim.

B、They work too hard.

C、They are too fat.

D、 They lost too much body fat.

2、Based upon the statistics given in the article, suppose there are 500 adult Americans, about how many of them will have a "weight problem"?____

A、 30.

B、 50.

C、100.

D、150.

3、Is there scientific evidence to support 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 show this is true.

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

D、We don't know because the information is not given

4、In comparison with the adult American population today, the Americans of ____.

A、ate more food and had more physical activities

B、ate less food but had more activities

C、 ate less food and had less physical exercise

D、had more weight problems

5、What have modern medical and scientific researches reported to us?____

A、Fat people eat less food and are less active.

B、 Fat people eat more food than slim people and are more active.

C、 Fat people eat more food than slim people but are less active.

D、 Thin people run less, but have greater increase in food intake.

Women who drank three or more cups of coffee a day were 30 percent less likely to have memory decline at age 65 than whose who drank one cup or less daily. And the benefit increased with age. Women over age 80 who drank three or more cups of coffee a day were about 70 percent less likely to have memory decline than those who drank one cup or less. the researchers said.

Caffeinated tea had the same effect in the women. the study found, although more was needed to get the same caffeine boost. "Count roughly two cups of tea for a cup of coffee," said study leader Karen Ritchie of INSERM, the French National Institute for Health and Medical Research. But the researchers didn&39;t find a similarly protective effect in men, although other studies have found a benefit to males.

How might caffeine help ward off cognitive decline？ "It is a cognitive stimulant." said Ritchie. It also helps to reduce levels of the protein called beta amyloid in the brain. she said. "whose accumulation is responsible for Alzheimer&39;s disease but which also occurs in normal aging."

Ritchie said she wasn&39;t sure why men in the study didn&39;t benefit from caffeine. "Our hypothesis is that either women metabolize caffeine differently than men, or there may be an interaction of the caffeine with the sex hormones.the estrogen-progesterone balance," she said.

The French study confirms previous research, said William Scott. professor of medicine at the University of Miami Miller School of Medicine. who has researched caffeine&39;s beneficial effects against Parkinson&39;s disease, also a neurodegenerative disorder.

As for caffeine only protecting women, Scott noted that just 2,800 of the 7,000 study participants were men. and the results might have differed if more men were included.

A study published in February in the European Journal of Clinical Nutrition looked at 676 healthy men and found that regular coffee drinkers had a lower rate of cognitive decline over a 10-year follow-up than those who didn&39;t drink coffee. Those who drank three cups daily had the least signs of decline. Both Scott and Ritchie agreed that more study is needed. Ritchie&39;s research will next look at the relationship between caffeine and Alzheimer&39;s.

阅读理解。

Only two countries in the advanced world provide no guarantee for paid leave from work to care for a

newborn child. Last spring one of the two, Australia, gave up the bad distinction by setting up paid family

leave starting in 2011. I wasn't surprised when this didn't make the news here in the United States-we're

now the only wealthy country without such a policy.

The United States does have one explicit family policy, the Family and Medical Leave Act, passed in 1993.

It entitles workers to as much as 12 weeks' unpaid leave for care of a newborn or dealing with a family

medical problem. Despite the modesty of the benefit, the Chamber of Commerce and other business groups

fought it bitterly, describing it as "government-run personnel management" and a "dangerous precedent (先

例)". In fact, every step of the way, as (usually) Democratic leaders have tried to introduce work-family

balance measures into the law, business groups have been strongly opposed.

As Yale law professor Anne Alstott, argues, justifying parental support depends on defining (定义) the

family as a social good that, in some sense, society must pay for. Parents are burdened in many ways in

their lives: there is "no exit" when it comes to children. Society expects-and needs-parents to provide their

children with continuity of care. And society expects-and needs-parents to persist in their roles for 18 years,

or longer if needed.

While most parents do this out of love, there are public punishments for not providing care. What parents

do, in other words, is of deep concern to the state, for the obvious reason that caring for children is not only

morally urgent but important to the future of society. To classify parenting as a personal choice for which

there is no collective responsibility is not merely to ignore the social benefits of good parenting; really, it is to

steal those benefits because they accrue (累积) to the whole of society as today's children become tomorrow's

citizens. In fact, by some estimates, the value of parental investments in children, investments of time and

money, is equal to 20%～30% of GDP. If these investments bring huge social benefits-as they clearly do-the

benefits of providing more social support for the family should be that much clearer.

1. What do we learn about paid family leave from Paragraph 1？

A. It came as a surprise when Australia adopted the policy.

B. Setting up this policy made Australia less influential.

C. It has now become a hot topic in the United States.

D. No such policy is applied in the United States.

2. What makes it hard to take work-family balance measures in the States？

A. The incompetence of the Democrats.

B. The opposition from business circles.

C. The lack of a precedent in American history.

D. The existing Family and Medical Leave Act.

3. What is Professor Anne Alstott's argument for parental support？

A. Children need continuous care.

B. Good parenting benefits society.

C. The cost of raising children has been growing.

D. The U. S. should keep up with other developed countries.

4. Why is the author against classifying parenting as a personal choice？

A. Parenting is regarded as a moral duty.

B. Parenting relies largely on social support.

C. Parenting produces huge moral benefits.

D. Parenting is basically a social
