| In the United States, it is not usual to telephone someone early in the morning. If you telephone early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. So it is with the telephone calls made after 11:00 pm. If someone receives a call during sleeping hours, he may think that it’s a matter of life and death. The time chosen for the call communicates its importance. In social life, time plays a very important part. In the USA guests tend to feel they are not highly regarded if the invitation to a dinner party reaches them only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of time is not the same in different cultures that treat time differently; being on time is valued highly in American life, for example. If people are not on time, they may be regarded as impolite or not fully responsible. In the USA no one would think of keeping a business friend for an hour; it would be too impolite. A person who is 5 minutes late is expected to make a shout apology. It he is less than 5 minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence. 1 A call at midnight would mean_________. A. the matter is less important B. the matter is too difficult to handle C. the matter requires immediate attention D. it is a matter of life and death 2. According to the passage, time plays a very important part in_______. A. everyday life B. private life C. getting along with others D. business 3. In the passage, the author suggests that invitation cards should be sent________. A. three or four days before the party date in all cultures B. three or four days before the party date in some cultures C. three or four days before the party date in the USA D. at your chosen time

科学实验活动册系列答案Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
The result：10％ fewer heart attacks. 8％ fewer strokes. 4％ fewer deaths. 11％ fewer new cases of heart disease. And 240 billion dollars in health care savings.
Researchers found it could prevent 10，000 heart attacks and 9。200 deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author. She says people would not even notice a difference in taste with three grams， or one-half teaspoon，less salt per day. The team also included researchers at Stanford and Columbia Uni versity.
Each gram of salt contains four hundred milligrams of sodium（钠），which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies， while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government interference.
Mayor Bloomberg has already succeeded in other areas， like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children’s Research Institute shows that the calorie information on the menu can influence what parents order for their children.
