Passage 2
Another thing an astronaut has to learn about is eating in space. Food is weightless, just as men are.
Food for space has to be packed in special ways. Some of it goes into tubes that a man can squeeze into his mouth. Bite-sized cookies are packed in plastic.
There is a good reason for covering each bite. The plastic keeps pieces of food from traveling in the spaceship. On the earth very small pieces of food would simply fall to the floor. But gravity doesn’t pull them to the floor when they are out of the plastic in a spaceship. They move here and there and can get into a man?s eyes or into the spaceship?s instruments. If any of the instruments is blocked, the astronauts may have trouble getting safely home.
As astronauts travel on longer space trips, they must take time to sleep. An astronaut can fit himself to his seat with a kind of seat belt .Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat. But be careful he must put his hands under the belt when he goes to sleep. This is because he is really afraid that he might touch one of controls that isn?t supposed to be touched until later. 36. Why would astronauts cover each bite of food in space？____ A. Because small pieces of food would fall down to the floor.
B. Because weightless pieces of food might make trouble when they travel around. C. Because they haven?t enough food for longer trips. D. because astronauts don?t want to waste food. 37. In a spaceship, astronauts can ____.
A. walk just as they do on the earth B. not eat anything because it?s dangerous C. control the spaceship when they are sleeping D. not litter small things or it will make trouble
38. In what way is food for space packed？___
A. Very small pieces of food are put on the floor. B. Some of it is put into tubes. C. Small-sized cookies are packed in plastic. D. Both B and C. 39. Why does an astronaut put his hand under his belt when he sleeps？____ A. Because he thinks it is comfortable to sleep in that way in space. B. Because he doesn?t want to touch any controls when he sleeps. C. Because the instruments of the spaceship are easily broken. D. Because he is afraid that the seat will move. 40. The best title of this article is ____. A. Eating and Sleeping in Space B. How Astronauts Eat in Space C. Food for Space
D. How Astronauts Sleep in Space
Passage 3
According to the American Automobile Association, since 1964 all cars sold in the United States have been equipped with seat belts. （These are also called safety belts.）Many studies
of auto mobile accidents have shown that safety belts can save lives. One study showed that forty percent of those killed in auto accidents could have been saved if they had been wearing seat belts.
Unfortunately belts are worn only by a small percentage of drivers and passengers--about fifteen percent in cities, and only nine percent in small towns. And safety belts cannot protect people who do not wear them.
In order to find out what kinds of people do wear seat belts, a study was made in several cities of the United States. The following facts were learned about those who use their safety belts:
1. They do not smoke while driving.
2. They have had more education than non-users.
3. They know someone who was injured(but not killed) in an automobile accident. Advertisements based on these facts have been printed in newspapers and magazines in order to teach people the importance of using seat belts. But these advertisements have not helped much. Some people believe there should be a law requiring drivers and passengers to use safety belts. In Australia, where there is such a law, deaths in auto accidents have decreased twenty-four percent.
41. The selection is mainly about ____. A. automobiles in the United States B. accident involving cars
C. safety belts for drivers and passengers D. traffic jams
42. The selection says that in Australia ____.
A. a law requires drivers and passengers to use seat belts B. about 50% of the drivers wear seat belts
C. the importance of seat belts is advertised in newspapers and magazines D. the auto accidents have kept the same percent 43. People who live in small towns _B__.
A. have fewer accidents than those who live in cities
B. are less likely to wear seat belts than those who live in cities C. tend to favour the passing of a law to require the use of seat belts D. are against the law that requires people to use seat belts
44. In Australia, where there is such a law, deaths in auto accidents have decreased ____. A. twenty-four percent B. fifty percent C. ten percent D. fifteen percent
45. Many studies have shown that seat belts can save lives of those ____. A. who never wear seat belts B. who seldom wear seat belts
C. who are wearing seat belts when the accidents happen D. who sit at the back of the cars Passage 4

odors.

Passage 5
In Melbourne, Australia, not long ago specialists gave advice on a patient?s problem. There?s nothing unusual in that except that the patient was in the far west of New South Wales at the time. That?s hundreds of miles from Melbourne. The heart disease experts were able to make their diagnosis after listening to the patient?s heartbeat over the telephone.
They were testing a new device that can change readings of a patient?s heartbeat into tone signals that can be sent by telephone. The device was designed in Australia. It is meant for use in areas far from large cities. Doctors in remote areas can take the heartbeat readings right in the patient?s home. Then they can play them over a telephone line to specialists in larger centers. The doctor in the remote area is thus able to get an expert?s opinion on the heart condition of his patient. Experiments with the device show that the whole process takes only a few minutes. Answer the questions:
36. This article is mainly about a device for ____. A. preventing heart disease B. sending medical information C. moving heart patients
D. recording doctors? conversations
37. Doctors in remote areas sometimes need advice because they don?t have ____. A. any training in medicine

D. the special knowledge needed to treat every condition 38. The readings are changed to tone signals in the ___. A. specialist?s office B. patient?s home C. city hospital D. radio station
39. Which happens last？ ____
A. The specialist makes his diagnosis. B. The doctor goes to the patient?s home.
