According to Paragraph 8, which of the following is true of ancient Egyptians？
A．It was normal to store beautiful artwork in the tomb with their dead relatives.
B．They would like to have all the valuables in the tomb to be exhibited in public.
C．They intended to preserve their ancient culture in the tomb.
D．They regard all the artwork in the tomb as part of a precious artistic heritage for all human beings to enjoy.
The question is not mere academic one. The case, 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 insistently for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the ease in industry tint 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.
One answer would seem to be longer periods on each shift, a month, or even three months. Recent research by Bonjer of the Netherlands, however, has shown that people on such systems will revert to their normal habits of sleep and wakefulness during the weekend and that this is quite enough to destroy any adaptation to night work built up during the week.
The only real solution appears to be to hand over the night shift to a corps of permanent night workers whose nocturnal wakefulness may persist through all weekends and holidays. An interesting study of the domestic life and health of night-shift workers was carried out by Brown. She found a high incidence of disturbed sleep, digestive discord and domestic disruption among those on alternating day and night shifts, but no abnormal occurrence of these symptoms among those on permanent night work.
The article is mainly about ______.
A．how the normal human daily cycle works
B．how to deal with the problem of shift work
C．a research on the normal human daily cycle
D．how to work better
To Err Is Human
Everyone must have had at least one personal experience with a computer error by this time. Bank balances are suddenly reported to have jumped from $ 379 into the millions, appeals for charitable contributions are mailed over and over to people with crazy sounding names at your address, department stores send the wrong bills, utility companies write that they're turning everything off, that sort of thing. If you manage to get in touch with someone and complain, you then get instantaneously typed, guilty letters from the same computer, saying, "Our computer was in error, and an adjustment is being made in your account."
These are supposed to be the sheerest, blindest accidents. Mistakes are not believed to be the normal behavior. of a good machine. If things go wrong, it must be a personal, human error, the result of fingering, tampering a button getting stuck, someone hitting the wrong key. The computer, at its normal best, is infallible.
I wonder whether this can be true. After all, the whole point of computers is that they represent an extension of the human brain, vastly improved upon but nonetheless human, superhuman maybe. A good computer can think clearly and quickly enough to beat you at chess, and some of them have even been programmed to write obscure verse. They can do anything we can do, and more besides.
It is not yet known whether a computer has its own consciousness, and it would be hard to find out about this. When you walk into one of those great balls now built for the huge machines, and standing listening, it is easy to imagine that the faint, distant noise are the sound of thinking, and the turning of the spools gives them the look of wild creatures rolling their eyes in the effort to concentrate, choking with information. But real thinking, and dreaming, are other matters. On the other hand, the evidence of something like an unconscious, equivalent to ours, are all around, in every mail. As extensions of the human brain, they have been constructed the same property of error, spontaneous, uncontrolled, and rich in possibilities.
The title of the writing "To Err Is Human" implies that ______.
A．making mistakes is confined only to human beings
B．every human being cannot avoid making mistakes
C．all human beings are always making mistakes
D．every human being is born to make bad mistakes

Sleep
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, broadly speaking, 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 case, 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 insistently 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 am to 4 pm the next, and 4 pm 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.
One answer would seem to be longer periods on each shift, a month, or even three months. Recent research by Bonjer of the Netherlands, however, has shown that people on such systems will revert to their normal habits of sleep and wakefulness during the weekend and that this is quite enough to destroy any adaptation to night work built up during the week.
The only real solution appears to be to hand over the night shift to a corps of permanent night workers whose nocturnal wakefulness may persist through all weekends and holidays. An interesting study of the domestic life and health of night-shift workers was carried out by Brown. She found a high incidence of disturbed sleep, digestive disorder and domestic disruption among those on alternating day and night shifts, but no abnormal occurrence of these symptoms among those on permanent night work.
The question raised in Paragraph 1 is "no mere academic one"
A．because Bonjer's findings are different from Brown's.
B．because sleep normally coincides with the hours of darkness.
C．because some people can change their sleeping habits easily.
D．because shift work in industry requires people to change their sleeping habits.
What Is Cancer？
Cancer is actually a group of many related diseases that all have to do with cells. Cells are the very small units that make up all(51)things, including the human body. There are billions of cells(52)each person's body.
Cancer happens when cells that are not normal grow(53)spread very fast. Normal body cells grow and divide and know when to stop growing. Over time, they also die.(54) these normal cells, cancer cells just continue to grow and divide out of control and don't die. Cancer cells usually group together to form. tumors (肿瘤).
A growing tumor becomes a lump of cancer cells(55) can destroy the normal cells around the(56) and damage the body's healthy tissues. This can make someone very(57) .
Sometimes cancer cells break away from the original tumor and travel to other areas of the(58) , where they keep growing and can go on to form. new tumors. This is how cancer(59) . The spread of a tumor to a new place in the body is(60) metastasis (转移).
People with cancer may feel pretty sick at times--but can usually still do lots of normal things.(61) they are very sick, kids and teenagers with cancer may still be able to go to school. They may be tired or bruise (出现青肿) easily, but they(62) sometimes go to camp, movies, and sleepover (在外过夜的) parties. People with cancer still like the same things they did(63) they got sick.
Cancer in kids is rare--but today, many kids who do get cancer go on living normal lives. The number of kids who beat cancer goes(64)every year because of new cancer treatments. So a lot of kids with cancer will some day drive cars, go to college, have careers, and even get(65) and have families of their own.
