Question 37 to 46 are based on the following passage.
It's our guilty pleasure: Watching TV is the most common everyday activity, after work and sleep, in many parts of the world. Americans view five hours of TV each day, and while we know that spending so much time sitting(37)_____ can lead to obesity(肥胖症)and other disease, researchers have now quantified just how(38)_____ being a couch potato can be.
In an analysis of data from eight large(39)_____ published studies, a Harvard-led group reported in the Journal of the American Medical Association that for every two hours per day spent channel(40)_____, the risk of developing Type 2 diabetes(糖尿病)rose 20% over 8.5 years, the risk of heart disease increased 15% over a(41)_____, and the odds of dying prematurely(42)_____ 13% during a seven-year follow-up.

As it is, sleep is so undervalued that getting by on fewer hours has become a badge of honor. Plus, we live in a culture that_____(36)to the late-nighter, from 24-hour grocery stores to online shopping sites that never close. It's no surprise, then, that more than half of American adults don't get the 7 to 9 hours of shut-eye every night as_____(37)by sleep experts.
Whether or not we can catch up on sleep-on the weekend, say-is a hotly_____(38)topic among sleep researches. The latest evidence suggests that while it isn't_____(39), it might help. When Liu, the UCLA sleep researcher and professor of medicine, brought_____(40)sleep-restricted people into the lab for a weekend of sleep during which they logged about 10 hours per night, they showed_____(41)in the ability of insulin(胰岛素)to process blood sugar. That suggests that catchup sleep may undo some but not all of the damage that sleep_____(42)causes, which is encouraging given how many adults don't get the hours they need each night. Still, Liu isn't_____(43)to endorse the habit of sleeping less and making up for it later.
Sleeping pills, while helpful for some, are not_____(44)an effective remedy either. “A sleeping pill will_____(45)one area of the brain, but there's never going to be a perfect sleeping pill, because you couldn't really replicates(复制)the different chemicals moving in and out of different parts of the brain to go through the different stages of sleep," says Dr.Nancy Collop, director of the Emory University Sleep Center.

Some adults require little sleep; others need eight to ten hours in every twenty-four. Infants sleep sixteen to eighteen hours daily, the amount gradually going less as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under pressure may manage on six to eight. Many famous people are repute to have required little sleep. Napoleon Bonaparte, Thomas Edison, and Charles Darwin apparently averaged only four to six hours a night.
(77) Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep routine; a favorite hour, a favorite bed, a favorite posture (姿势), and a formula (程式) you need to follow in order to rest comfortably.
(78)Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours nearly five days. Whatever the limit, it is absolute. Animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.
The writer implies that ______.
A．sleep is important for good mental and physical health
B．a light sleep is as restful as a deep sleep
C．memory is improved during sleep
D．sleep is relatively unimportant for human beings
Early in November 1965, New York was blacked out by an electricity failure (停电). The Mayor promised that it would not happen again. Pessimists (悲观主义者) were certain that it would happen again within five years. In July 1977, there was a repeat performance which produced a serious disorder throughout the city. At that time the city was in one of its worst heat waves.
In 1965, there was little crime during the darkness, and fewer than a hundred people were arrested. In 1977, hundreds of stores were broken into and looted (劫掠). Nearly 4,000 people were arrested but far more disappeared into the darkness of the night. The number of policeman available was far from enough and some looters even carry guns.
Hospitals had to treat hundreds of people cut by glass from shop windows. Banks and most business remained closed the next day. The blackout started at 9:30 P.M., when lightning hit and knocked out supply cables. Many stores were thus caught by surprise. For twenty-four hours, New York realized how helpless it was without electricity.
According to the first paragraph, who were right: the authorities or the pessimists？
A．The authorities.
B．The pessimists.
C．Both.
D．Neither.
Doctors have their own special sleep problems. Residents are famously short of sleep. It is not unusual for. them to work 40 hours in a row without rest. They are not in the least worried about it, confident they can still deliver the highest quality of medical care. But an article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person' s motor performance is comparable to that of someone who is drunk. Curiously, surgeons who believe that operating under the influence of alcohol is grounds for sacking often don' t think twice about operating without enough sleep.
"I could tell you horror stories," says Jaya Agrawal, president of the American Medical Student Association, which runs a website for residents. Some are terrifying." I was operating after being up for over 36 hours," one writes. "I literally fell asleep standing up and nearly planted my face into the wound."
"Practically every surgical resident I know has fallen asleep at the wheel driving home from work," writes another. "I know of three who have hit parked cars. Another hit a 'Jersey gate' on the New Jersey Expressway, going 105kin/h."
"Your own patients have become the enemy," writes a third, because they are "the one thing that stands between you and a few hours of sleep."
The U.S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own. If you're worded about the people treating you or a loved one, you should feel free to ask how many hours of sleep they have had and if more rested staffers are available.
Sleep is a funny thing because ______.
A．the longer one sleeps, the less sound sleep he gets
B．the more sleep one gets, the more likely a stroke occurs
C．many people stick to about eight hours of sleep to stay fine
D．many people who sleep six hours a night still feel energetic in the day
E-mail or electronic mail, is considered as the modem communication in the new age. It iscarried out in computers all over the world by millions of users. In this invisible world as many people call it,the users can send and receive letters to and from every comer of the earth.

But it is not a live talk—a real conversation like those in telephones.E-mailers compose letters at leisure on their computers, then send them by phone line to an on-line service,and then they go forward to the right place. A response can be back within hours,depending on how often the recipient(接受者)checks in.

Does this sound familiar？ You have probably read something like it in magazines or books, or seen it in a film. Why is it so popular？ One of the reasons is that it reflects the fears of many people; fear of the unknown fear of what is not understood or, at least, fear of something that is not completely understood.
The fact is that every day it seems that computers take control of another area of our lives. Some
factory jobs are now done by robots and the robots are controlled by computers. Our bank accounts are managed by computers. At the airport, our tickets are sold by a computer. Certainly, many of these operations are made more
efficient by computers, but our admiration is sometimes mixed with unsafe feelings. And this lack of safety is caused by the fact that we do not know how computers do these things, and we really don't know what they might do next. But we can find out how computers work, and once we understand them, we can use computers instead of worrying about being used by them. Today, there is a new generation of computer wizards who know exactly how computers get things done. These young men and women, usually university students, are happy to sit for hours, sometimes for days, designing programs, not eating, not sleeping, but discovering what can be done by these wonderful slaves which they have learned to control. These computer wizards have learned to use the computer and search for new tasks for their machines.

Questions 51 to 55 are based on the following passage.
Twenty years ago, the Urban Land Institute defined the two types of cities that dominated theUS landscape: smaller cities that operated around standard 9-5 business hours and largemetropolitan areas that ran all 24 hours of the day. Analyzing and comparing cities using thelens of this basic divide gives interesting context to how investment capital flows and housingprices have shifted.
In recent years, many mid-sized cities have begun to adopt a middle-of-the-road approachincorporating the excitement and opportunity of large cities with small cities&39; quiet aftermidnight. These 18-hour cities are beginning to make waves in real estate rankings and attractmore real estate investment. What is underlying this new movement in real estate, andwhy do these cities have so much appeal？
18-hour cities combine the best of 24-hour and 9-5 cities, which contributes to downtownrevitalization. For decades, many downtown cores in small to mid-sized cities were abandonedafter work hours by workers who lived in the suburbs. Movement out of city centers waswidespread, and downtown tenants were predominantly made up of the working poor. Thisgenerated little commerce for downtown businesses in the evenings, which made business andgenerating tax revenue for municipal upkeep difficult. With the rise of a new concept in urbanplanning that aims to make life easier and more convenient, however, increasing popularityfor urban areas that cased the real estate pushes, in major cities like San Francisco or NewYork, has inspired a type of forward thinking urbanity and in smaller cities.
Transforming downtown areas so that they incorporate modern housing and improvedwalkability to local restaurants, retail, and entertainment—especially when combined withimproved infrastructure for cyclists and public transit—makes them appeal to a more affluentdemographic. These adjustments encourage employers in the knowledge and talentindustries to keep their offices downtown. Access to foot traffic and proximity to transit allowthe type of entertainment-oriented businesses such as bars and restaurants to stay openlater, which attracts both younger, creative workers and baby boomers nearing retirementalike. Because of their smaller size, most keep hours that allow people to enjoy themselves, then have some quiet after midnight, as opposed to large major cities like New York, wherethe buzz of activity is ongoing.
These 18-hour cities are rapidly on the rise and offer great opportunities for homeownerinvestment. In many of these cities such as Denver, a diverse and vigorous economyattracted to the urban core has offered stable employment for residents. The right urban mixhas propped up home occupancy, increased property values, and attracted significantinvestment capital.
