Those ing from lands where time is looked upon differently may find this matter of pace to be one of their most difficult adjustments in both business and daily life.Many newers to the States will miss the opening courtesy of a business call, for example, they will miss the ritual socializing that goes with a weling cup of tea or coffee that may be traditional in their own country. They may miss leisurely business chats in a cafe or coffeehouse. Normally, Americans do not assess their visitors in such relaxed surroundings over prolonged small talks. We seek out evidence of past performance rather than evaluate a business colleague through social courtesies. Since we generally assess and probe professionally rather than socially, we start talking business very quickly.1. The statement that Americans are impolite to their business colleagues is wrong. __A__A. T B. F2. In the fourth paragraph, “a high priority” means “a first concern”.__A__A. T B. F3.

Fpassage5People born in the summer are more likely to be healthy than those who arrive during other times of the year, new research suggests. The phenomenon could be caused by mothers getting more sun in pregnancy — and passing on higher quantities of vitamin D to their unborn infant. A study of almost half a million British adults found babies born in June, July, and August were heavier at birth and taller as adults.For the first time the research also revealed girls born in the summer started puberty later — an indication of better health in adult life. Early puberty in girls has been linked with a higher risk of diabetes, heart disease or breast cancer.Previous research has shown children born between June and October are likely to be slightly taller and have bigger bones than winterborn children — believed to be related to vitamin D exposure during pregnancy.Babies born in autumn and winter are more likely to develop food allergies — with sunlight exposure during pregnancy and vitamin D levels also thought to play a role in this. But being born in summer can have drawbacks such as an increased risk of shortsightedness.1. According to the new research, babies born in summer are more likely to be A. T B. F2.

Fpassage6No one is glad to hear that his body has to be cut open by a surgeon and part of it taken out. Today, however, we needn’t worry about feeling pain during the operation. The sick person falls into a kind of sleep, and when he awakes, the operation is finished. But these happy conditions are fairly new. It is not many years since a man who had to have operation felt all its pain.Long ago, operation had usually to be done while the sick man could feel everything. Soon after 1770, Joseph Priestley discovered a gas which is now called “l(fā)aughing gas”. Laughing gas became known in America. Young men and women went to parties to try it. Most of them spent their time laughing, but one man at a party, Horace Wells, noticed that people didn’t seem to feel pain when they were using this gas. He decided to make an experiment on himself. He asked a friend to help him.Wells took some of the gas, and his friend pulled out one of Well’s teeth. Wells felt no pain at all. As he didn’t know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out. Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this terrible event.1. It is not long since a man felt all the pain while being A. T B. F2.

Fpassage7People in the United States honor their parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June.Mother’s Day was proclaimed a day for national observance by President Woodrow Wilson in 1915. Ann Jarvis from Grafton, West Virginia, had started the idea tohave a day to honor mothers. She was the one who chose the second Sunday in May and also began the custom of wearing a carnation.In 1909, Mrs. Dodd from Spokane, Washington, thought of the idea of a day to honor fathers. She wanted to honor her own father, William Smart. After her mother died, he had the responsibility of raising a family of five sons and a daughter. In 1910, the first Father’s Day was observed in Spokane. Senator Margaret Chase Smith helped to established Father’s Day as a national memorative day, in 1972.These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care.These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead．Many people attend
