根据短文内容,从下框的A~F选项中选出能概括每一段主题的最佳选项,并在答题卡上将该选项涂黑。选项中有一项为多余项。

A. Adults keep pets with their children

B. Pet –keeping has a very long history.

C. Pet-keeping may do harm to animals.

D. People keep pets for their aesthetic need.

E. Caged pets become increasingly popular.

F. Pet-keeping is helpful for children’s growth.

1.    Pet-keeping is a time-honored tradition. One of the reasons for people to raise dogs or cows was usefulness. While people in the past hunted animals and keep them in their backyards, the civilized man today is less cruel towards them and is less exploitative(利用的).

2.   We keep animals as pets because they are attractive. We all have the urge to possess something that has aesthetic(美学的) value, and that is why we treasure paintings or fine furniture. Keeping pets is one form of this urge. A Siamese cat in the house can be a decorative object. Pets are playful animals and they amuse us. A little rabbit amuses us by its playful and lively runs.

3.   Many people find it helpful to have pets in the house for their children. Having pets is an excellent way of developing in children the love of animals and responsibility. Children get the opportunity to take on full responsibility for another creature’s life. It will be an educational experience for a child to watch the natural life cycle of an animal. There are psychological (心理的) benefits for children. Pets are welcome friends for children who are lonely. Pets are excellent companions. Keeping pets means giving love and being loved. We find comfort in giving care and receiving care in return. We get pleasure from their appearance and their behavior.

4.    As more people move into apartments, there are limitations on keeping of animals like dogs and monkeys. Therefore, caged animals have increased in popularity. Birds fall into this group. We keep them for their beautiful songs and feathers. Fish-keeping is a widespread hobby and keeper can observe their behavior in the glass tank and study its entire life cycle. The cat is a fine house pet and it fits neatly into human habitation(居住地) without requiring its own cage. They are wonderful hunters, if there are rats around.

5.Pets satisfy man’s desire to care for a bit of nature. The pet owner has the responsibility for supplying those needs that nature provides. Pets are amusing and entertaining, but we are in a way doing animals harm by making them live in a human environment. Are we not enslaving(奴役) them?

Although Thomas Edison created the technologies behind three major 21st century industries  electrical power,recorded music and movies—his greatest invention may have been the modern method of inventing.He basically came up with the modern system of research and development.Edison was not the only scientist doing research in his garage but someone who gathered around him a team of creative scientific minds.Edison’s 1aboratories were the forerunners( 先驱)of Apple,Google and Microsoft.

Yet for a11 his scientific gifts,he was no Steve Jobs or Bill Gates.He once said,“Anything that won’ t sell,I don’ t want to invent.” But Edison,unlike Jobs or Gates,had no real sense of what the public wanted or how to change his discoveries into products that might sell.It took him years to understand that the phonograph( 留声机)was not a business tool but an entertainment invention.He helped create movies but resisted the idea that people might want to go into a theater to watch one.

We chose Edison this year because we need his example now more than ever.Though we live in a time of great reformation,the U.S.is in danger of losing its advantage in science and technology.American investment( 投资)in research and development has not increased as a percentage of GDP since the mid一1980s,while the government’ s share has been dropping.And this is at a time when China is rapidly increasing its money on research and development.The U.S.was once among the 1eading nations.Now it ranks near the bottom of the 23 nations that collect such data.We hope that Edison’ s story might not only encourage reformation but also inspire more

young Americans to study science and engineering.
