We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating(交替) with some 16-17 hours' wakefulness and that the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified.
The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed（颠倒的） routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts(轮班) are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently.
The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. She found a high incidence (发生率) of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work.
This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the pressure of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People occupied in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually go back to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance. Therefore, by taking body temperature at two-hour intervals(间隔时间) throughout the period of wakefulness, it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far, however, such a form of selection does not seem to have been applied in practice.
1.The main problem of the round-the-clock working system lies in .
A. the inconveniences brought about to the workers by the introduction of automation
B. the disturbance of the daily life cycle of workers who have to change shifts too frequently
C. the fact that people working at night are often less effective
D. the fact that it is difficult to find a number of good night workers
2.The best solution for implementing the 24-hour working system seems to be .
A. to change shifts at longer intervals.
B. to have longer shifts
C. to arrange for some people to work on night shifts only
D. to create better living conditions for night workers
3. It is possible to find out if a person has adapted to the changes of routine by measuring his body temperature because .
A. body temperature is higher when the cycle of sleep and wakefulness alternates
B. body temperature changes when he changes to night shift or back
C. the temperature reverses when the routine is changed
D. people have higher temperatures when they are working efficiently
4.Which of the following statements is NOT TRUE?
A. Body temperature may serve as an indication of a worker's performance.
B. The selection of a number of permanent night shift workers has proved to be the best solution to problems of the round-the- clock working system.
C. Taking body temperature at regular intervals can show how a person adapts to the changes of routine.
D. Disturbed sleep occurs less frequently among those on permanent night or day shifts.

As the mobile phones so widely appear in our daily life, someone said it would be cool if you didn’t have a mobile phone nowadays. It might be true to some extent, but as for an adult, a mobile means contact. It connects your work, relatives, friends, etc. It should do great deeds for us.
Months ago, my uncle gave his dear son a phone, because my nephew’s school is far from his home. He can only come back once a term, and the phones haven’t been so expensive yet. However, someone has criticized （批评） the young people for playing on mobiles, but not using. They are fond of sending messages, taking pictures and so on. They buy expensive, high level and fashion types for showing. They play on the mobiles day in and day out ….. Holy cow!
So, what happens to youngsters around you? Do they have a phone? What do they use it for? Do you think it’s necessary for teenagers who are still in school to have a phone?
POSTER 1:
In my view, mobile phones are only a tool for communication purpose, just like any other tools which have the potential (潜力) to be misused. In my opinion, I can see young people using it for security reason, emergency purpose, etc. If the parents can afford to pay big phone bills for their kids, well, that’s their business, like the old saying goes, “live and let live.”
--- Mary Smith
POSTER 2:
From psychological (心理学的) point of view, teenagers are more likely to be relaxed or pleasure-oriented. They would like to make something different. Buying brands that are considered “COOL” is important to them. They want others to like and admire themselves, and sometimes, even exaggerate(夸大)their own personality to show off. This can be seen as a kind of psychology during this certain range of age.
--- Dick Gates
Currently, people should tend to be more sociable, and age should not be seen as a barrier for teenagers to own their phones. They also need to set trends on the social circuit (社交圈). But here parents should play an important role in controlling their children about how to use the phones more properly.
1. We can learn from the first sentence of the passage that ________.
A. people admire those who don’t have mobile phones
B. people don’t like to have mobile phones nowadays
C. mobile phones are too popular among people now
D. mobile phones are not as useful as before
2. Why are some teenagers criticized according to the second paragraph?
A. They use mobile phones for playing instead of using.
B. They don’t use mobile phones for their study.
C. They play “Holy Cow” games in mobile phones.
D. They buy expensive, fashionable mobile phones.
3.By saying “live and let live”, Mary Smith means that _________.
A. teenagers shouldn’t use mobile phones
B. parents should buy mobile phones for their children
C. teenagers can use mobile phones if their parents don’t mind
D. teenagers should use mobile phones for communication
4.What is Dick Gates’ attitude towards whether teenagers should use mobile phones?
A. Supportive. B. Objective. （客观的）
C. Negative. （消极的） D. Uninterested.
