题目列表(包括答案和解析)

       American children aren’t the only couch potatoes. According to a study of over 70,000 teens in 34 nations, nearly 1/3 of children globally spend three hours a day or more watching TV or on computers. From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children aren’t getting enough exercise and it made no difference if they lived in a rich or a poor country. “With regard to physical activity levels, we did not find much of a difference between poor and rich countries, ” Guthold said. “ Growing up in a poor country does not necessarily mean that kids get more physical activity.” The study, published in The Journal of Pediatrics, looked at 72,845 schoolchildren aged 13 to 15 from North an South America, Asia, Europe, and the Middle East. The children were surveyed between 2003 and 2007.

       The researchers defined adequate physical activity as at least an hour of exercise outside of gym class at least five days a week. Children who spent three or more hours a day watching TV, playing computer games, or chatting with friends----except from time in school or time spent doing homework---were classified as sedentary (久坐的). The researchers found only 1/4 of the boys and 15% of girls were getting enough exercise by these definitions. 1/4 of boys and approximately 30% of girls were sedentary and didn’t get enough exercise with girls less active than boys in every country except from Zambia. While the study didn’t look at the reasons behind the lack of physical activity in various nations, it is believed that urbanization(城市化) could be a factor as well as to cars and TVs.

61.  What is the passage mainly about?

       A. A study about kids lacking physical activity.

       B. Why most kids are couch potatoes.

       C. What is adequate physical activity.

       D. Activity and a country’s development.

62.  What did Regina Guthold and her colleagues find according to the passage?

       A. Rural children get more physical activities.

       B. Boys get less physical exercise than girls.

       C. Children in rich countries enjoy better sports facilities

       D. Most children are lack of physical exercise.

63.  What does the speaker say about the study?

       A. It lasted for more than five years.

       B. It was carried out in America, Asia and Africa.

       C. It surveyed 72,000 school children.

       D. It defined how much exercise is enough.

64.  According to the passage, why can’t children get adequate physical activity?

       A. There is limited space for physical exercise.

       B. Urbanization results in the kids’ lack of activities.

       C. Children have great academic pressure.

       D. The education system neglects (忽视) physical health.

65.  Which of the following is Not True?

       A. Besides America, many countries’ children are couch potatoes.

       B. Sedentary refers to children who does not do enough exercise.

阅读短文,从每题所给的四个选项(A、B、C和D中选出最佳选项)

  Turning on the TV, a wonderful scene comes to your eyes-a group of men, tall, strong and handsome, and women, young, beautiful and attractive, too.Together they eat in the finest restaurants, traveling everywhere around the world by luxurious planes and pleasure ships.They are models.

  Do you envy them? What sort of life are models leading? Is it a wonderful life for a young lady or a young man?

  A few models are well-known actors or actresses who can make a lot of money only by showing themselves off in commercials.But the majority of them are just curious to see what it is like.They’d like to be models just because they are attracted by what they imagine-models earn a lot of money and lead a glorious life.This is true for those who are very successful.However, most models find it difficult to get work.Very few can earn enough to live on, and for all models their expenses are high.Their agents claim about 20% of the earnings, and no model will get very far without a clever agent.Besides, they have to buy good clothing.They also have to pay to travel to interviews and reach the places where the work is to be done.

  Interviews for a model job are known as cattle-markets in the modeling world, and not without a good reason.A top model can choose his or her work, demand and receive high fees and has his or her expenses paid.But for most models, the situation is quite different.And agent or employer inspects each model much as a farmer inspects cattle at a market.Intelligence, qualifications and personal characteristics count for little against good looks and tight figures.For all except the very few lucky ones, the life of a model is a continual search for work, trying to sell himself or herself in the face of fierce competition and, sometimes, not particularly moral standards on the part of some employers.

  Immigration officials at airport look suspiciously at a girl whose passport shows her occupation as “Model”, and these are men and women of considerable experience of the world.It comes no surprise to find that some models prefer to put “Secretary” or “Businessman” as their jobs in their passports.

  Modeling is a changeable world with great rewards for a tiny minority but not for the majority.

(1)

For models, their good looks and tight figures are ________.compared with their intelligence and qualifications.

[  ]

A.

more important

B.

less needed

C.

less essential

D.

more looked down upon

(2)

Which of the following can lead you to believe according to the passage?

[  ]

A.

A model’s traveling expenses are usually paid by his employer.

B.

To be a model, good looks are the most important qualification.

C.

Most models have a fairly easy way of life with high pay.

D.

A model can hardly be successful without a good agent.

(3)

Models often put “Secretary” or “Businessman” instead of “Model” in their passports because ________.

[  ]

A.

they want to avoid being stopped to sign their names by fans

B.

a person with the occupation of a model is easily attacked by black societies

C.

models are sometimes looked down upon

D.

secretaries and businessmen are free of custom duty

(4)

What may be the author’s attitude towards modeling?

[  ]

A.

It is a worthwhile life for a young lady or a young man.

B.

He is in favour of young people to try modeling.

C.

Before being crazy about a model job, young people should be aware of the difficulties.

D.

It is a field in which everyone has a great chance to succeed.

(5)

The underlined word “suspiciously” can most probably be replaced by ________.

[  ]

  NASA has opened the door to the next generation of space discovery by announcing great plans for a base for humans to live on the surface of the moon forever.

  The plan for the moon base, however, is the first detailed explanation of how NASA intends to prepare for the first manned exploration of deep space and a possible Mars mission within 30 years.

  Scientists also believe that the south pole on the moon contain rich natural gases such as the rare helium-3 that could be used as fuel for the generation of nuclear power.Besides, teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel.
