From the beginning rivers have played an important part in the life of man. Man of the ear

liest times used the rivers as a means of travel. Today rivers still serve as a great waterway for the transport and people.

In ancient times, man settled near rivers or on river banks and built up large empires.

Water is Nature's most precious gift to man. Man needs water to irrigate his crops, to cook and to wash. In nations all over the world rivers mean life and wealth. They feed and clothe the nations around them.

Water is also a source of energy and power. Man constructs huge dams across the river to control the water for irrigation and get the energy needed to drive generators. The electrical power is then directed to homes, cities, factories and television stations.

Man uses water each day. His main source of water comes from reservoirs, which in turn get their water from the rivers.

Rivers also bring down soil and minerals from the mountains and deposit them on the plains building up rich river deltas for raising plants and crops. Fresh water life in rivers or in lakes fed by them provide man with food.

In a small way rivers help to keep man in good health and provide for his amusements. Various forms of water sports keep man strong and healthy.

Rivers have run on this earth long before man. Man's future ability to live is uncertain, but rivers will flow on forever.

Rivers have been important to man ______.

A．since the last century

B．for a very long time

C．since a few hundred years ago

D．since a few years ago

第3题

A great difference between American social customs and those of other countries is the way in which names are used. Americans have little concern for “rank”, especially socially. Most Americans do not want to be treated in any especially respectful way because of their age or social rank; it makes them feel uncomfortable. Many Americans even find the terms “Mr.”, “Mrs” or “Miss” too formal. People of all ages may prefer to be called by their first names. “Don’t call me Mrs Smith. Ju call me Sally. ” Using only first names usually indicates friendliness and acceptance. However, if you do not feel comfortable using only first names, it is quite acceptable to be more formal. Just smile and say that after a while you will use first names but you are accustomed to being more when you first meet someone.

Very often, introductions are made using both first and last names: “ Mary Smith, this is John Jones. ” In this situation you are free to decide whether to call the lady “Mary” or “Miss Smith”. Sometimes both of you will begin a conversation using last names, and after a while one or both of you may begin using first names instead. You have a choice: if you don ’t want to use first names so quickly, no one will think it impolite if you continue according to you own custom.

A.Americans do not talk about rank, especially socially

第6题

Some people think they have an answer to the troubles of automobile crowding and dirty air in large cities. Their answer is the bicycle, or" bike".

In a great many cities, hundreds of people ride bicycles to work every day. In New York City, some bike riders have even formed a group called Bike for a Better City. They claim that if more people rode bi- cycles to work there would be fewer automobiles in the downtown section of the city and therefore less dirty air from car engines.

For several years this group has been trying to get the city government to help bike riders. For example, they want the city to draw bicycle lanes on some of the main streets, because when bike riders must use the same lanes as cars, there are accidents. Bike for a Better City feels that if there were special lanes more people would use bikes.

But no bicycle lanes have been drawn. Not everyone thinks it is agood idea--they say it will slow traffic. Some store owners on the main streets say that if there is less traffic, they will have less business. And most people live too far from downtown to travel by bike.

The city government has not yet decided what to do. It wants to keep everyone happy. Only on week- ends, Central Park is closed to cars, and the roads may be used by bicycles only, but Bike for a Better City says that this is not enough and keeps fighting to get bicycle lanes downtown.

According to the passage, bicycles ______.

A．are more convenient than cars

B．are safer traffic tools than cars

C．are ridden by most people in U．S．

D．are the solution to some city problems
