Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
When a magazine for high school students asked its readers what life would be like in twenty years. They said machines would be run by solar power. Buildings would rotate so they could follow the sun to take maxi- mum advantage of its light and heat. Walls would "radiate tight" and "change color with the push of a button". Food would be replaced by pills. School would be taught by "electrical impulse" while we sleep. Cars would have radar. Does this sound like the year 2000？ Actually, the article was written in 1958 and the question was, "what will life be like in 19787？"
The future is much too important to simply guess about the way the high school students did, so experts are regularly asked to predict accurately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But Can they？ One expert on cities wrote: cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in "airbuses", large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard of". Does that sound familiar？ If the expert had been accurate, it would because he was writing in 1957. His subject was "the city of 1982".
If the professionals sometimes sound like high school students, it's probably because future study is still a new field. But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accurate, and generally it is. But there have been some big mistakes in this field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, mining thousands of investors who had put their faith financial foreseers.
One forecaster knew that predictions about the future would always be subject to significant errors. In1957, H.J. Rand of the Bad Corporation was asked about the year 2000, "only one thing is certain" he answered, "Children born today will have reached the age of 43."
The high school students' answers to "what would life be like in 1978" sound ______.
The fort of Japanese male chauvinism—the old guard of the ruling Liberal Democratic Party has unintentionally done more than most to, change all that. The sex scandal that marked the brief prime ministership of Mr. Sosuke Uno last summer outraged many women, and helped the opposition to its success in, the upperhouse election in July. Mr. Uno is forgotten, but the resentment (怨恨)of women about their treatment at the hands of men lingers (逗留) on. Over the past few months Japanese women have started campaigning much more vigorously for laws to protect them from sexual bothering at work.
Japan's first lawsuit claiming sexual bothering opened last week in a city court in Fukuoka. A 32-yeasold woman, whose name has been kept from being known (another first), is seeking about ＄26000 in damages from her former boss and the publishing company she worked for. She claims his sexual hints forced her to leave the company and give up her career. She stakes her claim on the ground, among others, that her rights under article 14 of the Japanese constitution were violated. This guarantees equal treatment for the sexes.
Women's lobbying groups have been springing up all over Japan. The lead has been taken by lawyers at the Second Bar Association in Tokyo. Last month the association held a call-in for women to expose their grievances. Its telephone lines were jammed for six hours. By the end of the session, some 137 formal complaints had been registered. "Nearly 40% of them were from women who had been compelled to have sexual relations with their superiors at work", says Miss Shizuko Sugii, a lawyer with the bar association. Ten of the eases have since been classified as rape or attempted rape.
This passage mainly talks about things in______.
M: Mom and Dad want to have all the family back home this year, so that's where we'll be. How about you？
W: I plan on having everyone over to my place this year. It really is a lot of work, but I love having my family all together and I like to entertain.
M: You are such a good cook. I'll bet your family loves coming to your place, too.
W: I don't do all the cooking myself. I think everyone enjoys it a little more if they each bring something they have made.
M: Do you have traditional dishes that you serve every year？ I know our family does.
W: Yes, we do. We always have turkey and dressing, mashed potatoes and gravy and, of course, sweet potatoes. I think those are traditional dishes for most families. There is a fruit salad that we have every year and every one looks forward to my pumpkin pie.
M: What do the men in your family do while the women are doing the cooking？
W: It's the same every year—football. They watch one game after another on Thanksgiving. I tell them that they ought to go out and get some exercise, but they just can' t get away from the TV.
M: I know a lot of men are like that. After dinner we like to go bowling. It's a fun thing to do together as a family. After a couple of games, we go back home and eat the left food.
W: I like that about Thanksgiving. We cook so much food that we have leftovers to last for several meals and I don't have to cook.
