“Before you fall in love, you'd better get a job”

As told by Lee Joon-ho, 20, a senior in law at Seoul National University

    Korean TV dramas have shown a lot of rebellious(反叛的) youth, but in fact most students still live a traditional life.

Confucianism has a great influence on us. For instance, Confucius said that we should be dutiful to our parents and value the family. Thus we prefer a school that's close to home so we can go back every day.

Also as a result of Confucianism, teachers enjoy a high status in Korea. The other day, my professor was flying to Vienna on a business trip. Instead of waiting for hours in the queue, he was told to check in first and didn't have any problem with overweight luggage.

When it comes to important decision-making, such as choosing a university, a job, and a wife, we listen to our parents' suggestions. Most parents seem liberal in study decisions, but they take a firmer attitude towards their children's love and marriage choices. Often, a man has to have his own business or a solid career before he's allowed to pursue romance.

Male chauvinism is popular among our parents' generation, since they had to support the whole family through hard work. We need to shoulder the same responsibility, but we've also learned to respect women, as they're doing outstanding work in lots of areas. But to be honest, my friends and I still prefer a traditional woman as a girlfriend and future wife. We want her to be elegant and thoughtful in taking care of a family.

Our sense of tradition is also reflected in our buying habits. In my house, you see only Korean appliances. Although European cell phones are available in ROK, we favor LG and Samsung, which are suited more to our tastes and widely promoted in TV dramas and films.

C. Korean cell phones are traditional.

D. The Korean people have a sense of tradition.

4.What is the passage mainly about?              

A. Korean youth are rebellious.

B. Korean youth will not love anyone until they find a job.

C. Most Korea students live a traditional life.

D. Confucius has a great influence on the Korean people.

 

 

The effects of rapid travel on the body are actually far more disturbing than we realize. Jet Lag is not a psychological consequence of having to readjust to a different time zone. It is due to changes in the body’s physiological regulatory mechanisms, specifically the hormonal systems, in a different environment.

     Now that we understand what Jet Lag is, we can go some way to overcome it. A great number of the body’s events are scheduled to occur at a certain time of day. Naturally these have to be regulated, and there are two regulatory systems which interact.

    One timing system comes from the evidence of our senses and stomachs, and the periodicity we experience when living in a particular time zone. The other belongs in our internal clocks (the major one of which may be physically located in a part of the brain called the suprachiasmatic nucleus) which, left alone, would tie the body to a 25-hour rhythm. Normally the two timers are in step, and the surroundings tend to regularize the internal clocks to the more convenient 24-hour period.

     If, however, you move the whole body to a time zone which is four hours different, the two clocks will be out of step, like two alarm clocks which are normally set together, but which have been reset a few hours apart. Whereas the two clocks would normally sound their alarms together, now they ring at different times. Similarly, the body can be set for evening while the sun is rising.

     In time the physiological system will reset itself, but it does take time. One easily monitored rhythm is palm sweating. A man flown to a time zone different by 10 hours will take eight days to readjust his palm sweat. Blood pressure, which is also rhythmical, takes four days to readjust.

What can we do about it? It is not feasible to wait four days until the body is used to the new time zone. Fortunately there is a short cut. It relies on two things-the power of the stomach to regulate the timing of other events, and the pharmacological actions of coffee. The basic assumptions are:

Coffee delays the body clock in the morning, and advances it at night. Coffee at mid-afternoon is neutral. Protein in meals stimulates wakefulness, while carbohydrates promote sleep. Putting food into an empty stomach helps synchronize the body clock.

46. What is jet lag associated with?

  A. Psychological change.            B. Physiological change.

  C. Inexperience of rapid travel.       D. Unfamiliar environment.

47. What helps us to adjust to a 24-hour rhythm?

  A. Alarm clock.                   B. Suprachiasmatic nucleus in our brain.

  C. Signals from outside of the body.   D. Our senses and stomachs.

48. What do we know from the fifth paragraph?

  A. A person moving to a different time zone will suffer from high blood pressure.

  B. A person moving to a different time zone will sweat a lot.

  C. Moving to a different time zone will affect both palm sweat and blood pressure.

  D. If the rhythm of blood pressure and palm sweat are not in step, there will be jet lag.

49. What should we do if we want to stay awake?

  A. To take coffee at three o’clock in the afternoon.

  B. To have meals that contain lots of protein.

  C. To have some carbohydrate drinks.

  D. To stop putting food into our stomach.

50. How can we cure jet lag?

   A. To sleep for days.      B. To wait for self-recovery.

   C. To drink tea.           D. To get something to eat.

 

 

Anyone for rocket salad?        The Chinese are now growing huge vegetables from seeds they sent into space.

If you’re the type who worries about the air miles traveled by fruits and vegetables,  these beauties aren’t for you. It’s because they have traveled a little further than most.

The seeds from which they grew were fired into space, where they orbited the earth for two weeks. Once they returned they were grown in hothouses, producing the monster kinds seen here.

China, which is behind these space fruits and vegetables, says they could be the answer to the world’s food crisis.

The 21-pound tomatoes, nine-inch chilies, 15-stone pumpkins and large watermelons growing at the Guangdong Academy of Agricultural Sciences’ hothouses can feed many more than their smaller cousins, and may have more nutrients, the scientists say.

Researcher Lo Zhigang said, “Traditional agricultural development has taken us as far as we can go and demand for food from a growing population is endless. Space seeds offer the opportunity to grow fruits and vegetables bigger and faster.”

He admitted he and his colleagues could not explain why time in orbit caused the seeds to change genetic structure. But they guessed exposure to the cosmic(宇宙的) radiation that attacked the spacecraft in orbit, as well as the near zero gravity conditions, microgravity, could play a part.

“We don’t think there’s any threat to human health because the genes themselves do not change; just their order changes,” he said. “With genetically-modified(GM) crops you have seen environmental problems because they have added genes that can damage other organisms. But with space seeds they don’t gain genes; they can only lose them.”

He also claimed the Vitamin C content in some space vegetables was nearly three times higher than in common vegetables, while levels of zinc are also increased.

Western scientists are doubtful. NASA researchers who have experimented with seeds in space say there is not enough benefit to show the cost is reasonable.

72. What do the underlined words “these beauties” in paragraph 2 probably refer to?

         A. Beautiful views along the air routes.           B. Traveling experiences in space.

         C. Seeds fired into space.                                     D. Giant vegetables.

73. We can infer from Lo’s words in paragraph 6 that       .

         A. our conventional agriculture has developed too slowly

         B. we are asking too much from nature

         C. space seeds may help meet our demand for food

         D. we’ll grow crops in space in the future

74. Why the seeds changed their genetic structure      .

         A. remains to be proved                                      

    B. is discovered by Lo Zhigang

         C. has something to do with die conditions in hothouses

         D. is due to the radiation that attacked them directly

75. Comparing Gm crops and space crops, we can see that      .

         A. space crops grow faster                                 

    B. space crops are more environmentally friendly

         C. GM crops are less a threat to human health  

    D. GM crops have fewer nutrients
