Although the United States covers so much land and the land produces far more food than the present population needs, its people are by now almost entirely an urban society. Less than a tenth of the people are engaged in agriculture and forestry(林業(yè)), and most of the rest live in or around towns, small and large. Here the traditional picture is changing: every small town may still be very like other small towns, and the typical small town may represent a widely accepted view of the country, but most Americans do not live in small towns any more. Half the population now lives in some thirty metropolitan areas(large cities with their suburbs ) of more than a million people each – a large proportion than in Germany or English, let alone France. The statistics(統(tǒng)計(jì)) of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day. As the rush to live out of town continues, rural areas within reach of towns are gradually filled with houses, so that it is hard to say at what moment a piece of country becomes a suburb. But more and more the typical American lives in a metropolitan rather than a small town environment.

1.If now America has 250 million people．how many of them are engaged in agriculture and forestry?

A．About 25 million． B．More than 25 million．

C．Less than 25 million． D. Less than 225 million．

2.Which of the following four countries has the smallest proportion of people living in metropolitan areas?

A．United States B．Germany C．France D．England

3.What’s the meaning of the word “metropolitan” in the middle of the passage?

A. Of a large city with its suburbs．

B．Of small and large towns．

C．Of urban areas．

D．Of rural areas．

4. According to the passage，what can we learn about small towns in the United States?

A．Most small towns become gradually crowded．

B．Small towns are still similar to each other．

C．As the traditional picture is changing，towns are different．

D .Small towns are turning into large cities．

5.Why is it hard to say when a piece of country becomes a suburb?

A.Because they are the same．

B．Because the rush takes place too quickly．

C．Because the process is gradual．

D．Because more and more Americans live in metropolitan areas．

We live in a sweet world. The average American kid consumes more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn’t good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to conduct a study on the negative effects of sugar. They found it could have serious effects on people’s health.

Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers.

During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice were 26% less territorial and produced 25% fewer offspring than the other mice.

Scientists often use mice for research because they have a similar genetic（基因） structure to humans. “Since most substances that are dangerous in mice are also dangerous in people, it’s likely that those physical problems that cause those mice to have increased deaths also work in people,” says study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives.

Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation’s sugar desire will provide for a truly sweeter future.

1.The study conducted by researchers aimed at learning about________

A. the advantages and disadvantages of sugar

B. the negative effects of sugar on people’s health

C. the genetic structure of mice

D. American’s diet

2.According to the study, which of the following statements is wrong?

A. Sugar can even shorten lives.

B. Sugar’s negative effects are not noticeable.

C. Mice are more likely to diet when fed a diet containing 25% more sugar.

D. Eating much more sugar can make mice put on weight and get high blood pressure.

3.From the passage we can infer_______

A. sugar plays a very important role in Americans’ diet

B. kids consume more sugar than adults in America

C. the study on human beings lasted 58 weeks

D. the genetic structure of mice is totally different from that of people

4.What’s the best title of the passage?

A. Living a sweet life

B. Kids consume much more sugar

C. Genetic structure of humans

D. Danger of sugar
