Q: Write a multi-choice question for the following article, with the given choices and answer: Article: We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating 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 routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts 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 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... Options: 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 Answer: B the disturbance of the daily life cycle of workers who have to change shifts too frequently Question:
A: The main problem of the round-the-clock working system lies in _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer just under the surface.The outside dead layers wear off all the time,with new ones replacing them,and the body forms a totally new skin every three weeks. The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria can't get in through the skin unless it is damaged. If the weather is cold,the blood vessels in the skin squeeze down,or contract ,so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even "blue".At the same time,the hairs on the skin are pulled upright by tiny muscles. When it is hot,the blood vessels expand ,or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands produce more sweat,which cools the skin. If your skin has ever been numb ,you will realize how important the feeling from the skin is.Nerves in the skin are sensitive to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways. The colour of the skin depends on special colour cells .These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may "tan" in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones. Options: A when one's skin is numb B when one is ill C when the skin is cut D when the sweat glands produce more sweat Answer: C when the skin is cut Question:
Answer: Bacteria will get in through the skin _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: A funny thing happened on the way to the communication revolution: we stopped talking to one another. I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and suddenly, I became invisible, absent from the conversation. The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communication technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice-mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine. As almost every contact we can imagine between human beings gets automated, the emotional distance index goes up. You can't even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated. I am not against modern technology. I own a cell phone, an ATM card, a voice-mail system, and an email account. Giving them up isn't wise. They're a great help to us. It's some of their possible consequences that make me feel uneasy. More and more, I find myself hiding behind email to do a job meant for conversations or being relieved with voice-mail picking up because I don't really have time to talk. The industry devoted to helping me keep in touch is making me lonelier. Options: A The Advance of Modern Technology B The Consequences of Communication Technology C The Story of Communication Revolution D The Automation of Modern Communication Answer: B The Consequences of Communication Technology Question:
