(76) Concerning money or anything else, conflicts between husband and wife usually reflect a power straggle. Conflicts between parent and child often center around the same issue. As children enter adolescence, they begin to demand greater freedom to go where they please, do what they please, and make decisions without parental interference. Many American parents do not know how to deal with their teenagers and seek advice from books, lectures, and parent training courses. Par-ents want to maintain a friendly relationship with their teenagers and also want to guide them so that their behavior will be whatever the parents consider proper and constructive.
But in a society of rapidly changing social and moral values, parents and children often disagree about what is important and what is fight.
(77) Arguments may concern such unimportant matters as styles of dress or hairdos. But quar-rels may also concern school work, after school jobs, decisions, use of the family car, dating, and sex behavior. Some families have serious problems with teenagers who drop out of school, run away from home, or use illegal drugs. Because so much publicity is given to the problem teenager,one gets the impression that all teenagers are troublemakers. Actually, relatively few adolescents do anything wrong, and nearly all grow up into "solid citizens" who fulfill most of their parents' ex-pectations. In fact, recent studies show that the "generation gap" is narrowing. The vast majority of teenagers share most of their parents' values and ideas. Many parents feel that they get along with their adolescents quite well.

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 travelling 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. (78) They move here and there and can get into a man' s eyes or into the spaceship' s instruments. If any of the instru-ments is blocked, the astronauts may have trouble getting safely home.

Questions 11 to 15 are based on the following passage:
The Chinese have used a method called acupuncture(针灸) to perform operations for about 4,000 years without putting the patient to sleep. This involves placing flexible needles into certain parts of the body. The needles are available in a number of stores in China and anyone may buy them.
To learn how to use the needles takes about one month of training. But to be skillful requires greater time. (79) The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful. This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed. A particular operation might require 25 or more needles placed in various parts of the body. But now this operation re-quires only 3 or 4 needles.
Today, the Chinese doctors are trying to learn more about acupuncture. (80) They are trying to develop a convincing theory to explain how the needles work in preventing pain, or why a nee-dle in the wrist, for example, would prevent the pain in the area of the mouth.
A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep. It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation but the chemical may make the patient sick for a few hours or a day.
