题目列表(包括答案和解析)

阅读理解。
     Sales of laptop computers passed desktops (台式电脑) in the US for the first time ever this fall, according
to market research firm IDC.
     That' s bad news for backs, necks and shoulders.
     "Laptops are basically not designed based on human bodies-unless you' re 2 feet tall," says physician
Norman J. Marcus, a muscle (肌肉 ) specialist in New York City.
     When you work at a computer, the keyboard should be at elbow height, so your upper and lower arms
form an angle (角度) of 90 degrees or more. The monitor (显示器) should be at about eye level so you can
rest back in a chair with back support.
     But most users simply set their laptops on a desk or table. The keyboard is too high, which makes your
arms reach up, your shoulders rise and your wrists (手腕) bend down. The monitor is too low, which pulls
your head and neck forward and down and this may hurt your back.
     That' s OK if you use your laptop occasionally, for short periods. But if you use one for hours without
stopping-as do millions of college students, business travelers, video-gamers and growing numbers of office
workers-you' re setting yourself up for muscle problems that can make your entire upper body hurt.
      Experts have warned about laptop problems for years-but without success. People continue to abandon
large and heavy desktops in favor of the smaller and lighter laptops. And WiFi (无线局域网 ) connections let
us use laptops anywhere-in bed, on the floor-and in all kinds of positions.
1. What Norman J. Marcus says in Paragraph 3 means _____ .
A. laptops are so badly designed
B. muscle pains are mainly caused by laptops
C. laptops are not suitable for people of usual height
D. laptops cause a lot of diseases easily
2. It can be known from the passage that ______.
A. we had better not use laptops too frequently
B. there are no suitable places for laptops
C. we shall buy desktops instead of laptops
D. desktops will face a hard future
3. Which of the following statements can be learned from the passage?
A. Using laptops doesn' t do harm to people' s health.
B. People pay little attention to the risks of laptop use.
C. Most people use laptops more often than desktops.
D. Laptops bring people more disadvantages than advantages.
4. The main purpose of the passage is to _____ .
A. show that laptops are widely used in the US
B. tell us people prefer laptops to desktops
C. persuade people not to use laptops any more
D. warn people of health problems caused by laptops

第三部分:阅读理解(共20小题,每题2分,满分40分)

                               Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease.

New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting.

But the good news is that doing chores (家务杂事) in the house or gently walking around the office while on the phone might be enough to keep you fit.

The study joins the growing body of evidence suggesting too much sitting might undo the benefits of exercise.

The study measured the intensity (强度) of physical activities in 168 subjects over seven days. It found that, regardless of how much exercise they did or their total sitting time, those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids (脂质).

“Higher levels of blood lipids have been linked to a heightened risk of heart disease,” principal researcher Genevieve Healy of the University of Queensland said. “What the study shows is that there are benefits in just getting up regularly and interrupting your sitting time.”

Researchers behind the Stand Up Australia project have written to the Rudd Government requesting $3.5 million for a two-year study into how long sitting affects health and productivity of workers. The study would also develop and test strategies for reducing sitting time on the job.

The latest study builds on work that is shifting the health promotion focus from purposeful exercise, such as running, to lower intensity activities throughout the day.

The Australian research has been backed up by US studies.

“To hold a body that weighs 77 kilograms upright takes a fair amount of energy from muscles,” said Professor Marc Hamilton from the University of Missouri. “There is a large amount of energy associated with standing every day that cannot be easily replaced by 30 to 60 minutes in the gym.”

56.The study shows that            .

A. exercising for 30 minutes in the gym is good after sitting too long

B. walking is the best physical activity after sitting too long

C. sitting too long in the office causes the waist to expand

D. having breaks from sitting is good for your health

57.What’s the aim of the Stand Up Australia project?

A. To develop and test strategies for reducing working time.

B. To study the reasons for the longer sitting time in the office.

C. To develop and test strategies for reducing sitting time at work.

D. To study the factors influencing productivity of workers.

58.The purpose of the last paragraph is to        .

A. provide a scientific basis for the benefits of standing up

B. compare the effect of standing with exercising in the gym

C. report the new research findings of Professor Marc Hamilton

D. figure out the amount of energy associated with daily standing

59.The health promotion focus used to be on         .

A. purposeful exercise                        B. running

C. lower intensity activities              D. long sitting

60.What’s the best title for the text?

 A. Exercise in the Gym Is Out                  B. Your Office Chair Is Killing You

 C. A Cause of Heart Disease          D. Good News for Workers

The fourth round of heavy smog to hit Beijing in four weeks has sent more people to the hospital with respiratory (呼吸的) illnesses and led to calls for laws to control the pollution.

Pan Shiyi, a celebrity, said he is planning to propose a Clean Air Act to the local government. As a representative to the Beijing Municipal People's Congress, he started an online survey at 9:20 a.m. Within three hours, more than 25,000 web users, or 99 percent of total respondents (应答者) , welcomed his proposal.

They have good reasons to stand alongside Pan. The latest round of haze(雾霾)reduced visibility to under 500 meters in many parts of the city. The smog has also led to a great increase in respiratory illnesses, particularly among children and the elderly. Anxious parents and doctors almost all blame the smoggy air for the illnesses. Though most schoolchildren are home for the winter holidays, the bad air can easily move indoors. Besides, ordinary medical masks fail to provide enough protection, so some people have turned to gas masks.

The causes of the frightening smog are rather mysterious, though experts blame too much emissions (排放) and the mountains around Beijing that trap pollution in winter, unless there is enough wind to clear it away. Some critics blamed China’s top two oil firms, China National Petroleum Corp and China Petrochemical Corporation, saying the companies’ outdated production technologies produce large quantities of high-polluting gas fuel.

Meanwhile, some Beijingers have moved their brainstorming discussion to computers. If Pan’s proposal for a Clean Air Act is adopted, netizens say the new law should include items providing for “car-free days” in times of smog, higher standards for vehicle fuel, stricter limit to industrial and engine gas emissions, and more effective protection for the public.

Beijing is not the only city that has ever lost the blue sky. Five days of thick fog caused thousands of deaths in Britain in December 1952, urging the government to pass the first Clean Air Act in 1956, which introduced smokeless zones and cleaner fuels to reduce pollution. That may provide some experience for Beijing to refer to.

1.Why did Pan Shiyi started an online survey?

A. To know the public’s opinions on pollution

B. To tell people the danger of the smoggy weather

C. To call on people to support his proposal

D. To collect supporting evidence for his proposal

2.What can we learn from the passage?

A. People are clear about the causes of the smoggy weather.

B. Children staying indoors will not get respiratory illnesses.

C. Smog is worse for people with lower resistance to diseases.

D. Masks can give people protection against the smoggy weather.

3.Britain is mentioned in the last paragraph to ______.

A. suggest Beijing should learn from other countries

B. let people know many places have this problem

C. tell people the situation in Britain is worse

D. call on the government to pass Britain’s Clean Air Act

4. What’s the best title for this passage?

A. The Use of Gas masks and Engines

B. Beijingers Call for Clean Air Act

C. Effective Protection for Blue Sky

D. The Mysterious Causes of the Scary Smog
