Leading a dog’s life in America isn’t such a bad thing. Many grocery stores sell pet foods to owners eager to please their pets. In Houston, Texas, dogs can have their dinner delivered to their homes, just like pizza. Well-to-do canines can attend doggy daycare centers while their owners work. Pets can even accompany their owners on vacation. Fancy hotels are beginning to accommodate both man and beast. Furry guests in hotels can enjoy gourmet meals served on fine china and sleep in soft beds.Beneath the furry luxuries, there lies a basic American belief: Pets have a right to be treated well. At least 75 animal welfare organizations exist in America. These provide care and adoption services for homeless and abused animals. Vets can give animals an incredible level of medical care for an incredible price. To pay for the high-tech health care, people can buy health insurance for their pets. And when it’s time to say good -bye, owners can bury their pets in a respectable pet cemetery.The average American enjoys having pets around, and for good reason. Researchers have discovered that interacting with animals lowers a person’s blood pressure. Dogs can offer protection from burglars and unwelcome visitors. Cats can help rid the home of unwanted pests. Little creatures of all shapes and sizes can provide companionship and love. In many cases, having a pet prepares a young couple for the responsibilities of parenthood. Pets even encourage social relationships: They give their owners an appearance of friendliness, and they provide a good topic of conversation.Pets are as basic to American culture as hot dogs or apple pies. To Americans, pets are not just property, but a part of the family.

Emotions(情感)like these suggest that a positive spirit still lies behind gift giving. They prove that the anthropologist Claude Levi-Strauss was wrong to say that modern western gift giving is highly wasteful. Studies in Canada and elsewhere have also shown that this is not the case. Each gift is unique even if so many are given.The emotional benefit for those who exchange gifts is the very reason for the tradition to continue.

共用题干第三篇The Science of the FutureUntil recently,the"science of the future"was supposed to be electronics and artificial intelligence.Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering.This combination is the science of biotechnology.Organic chemistry enables us to produce marvelous synthetic（合成的）materials. However,it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture.Nothing that we have been able to produce so far comes anywhere near the combination of strength,lightness and flexibility that we find in the bodies of ordinary insects.Nevertheless,scientists in the laboratory have already succeeded in"growing"a material that has many of the characteristics of human skin.The next step may well be "biotech hearts and eyes"which can replace diseased organs in human beings.These will not be rejected by the body,as is the case with organs from humans.The application of biotechnology to energy production seems even more promising.In 1 996 the famous science-fiction writer,Arthur C. Clarke,many of whose previous predictions have come true,said that we may soon be able to develop remarkably cheap and renewable sources of energy.Some of these power sources will be biological.Clarke and others have warned us repeatedly that sooner or later we will have to give up ourdependence on non-renewable power sources.Coal,oil and gas are indeed convenient. However,using them also means creating dangerously high levels of pollution.It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic（灾难性的）levels unless we develop power sources that are both cheaper and cleaner.It is attempting to think that biotechnology or some other"science of the future"can solve our problems.Before we surrender to that temptation we should remember nuclear power.Only a few generations ago it seemed to promise limitless,cheap and safe energy.Today those promises lie buried in a concrete grave in a place called Chernobyl,in the Ukraine.Biotechnology is unlikely,however,to break its promises in quite the same or such a dangerous way.According to the passage,it may soon be possibleA:to make something as good as human skin.B:to produce drugs without side effects.C:to transplant human organs.D:to make artificial hearts and eyes.

Among the most popular books being written today are those which are usually classified as science fiction. Hundreds of titles are published every year and are read by all kinds of people.Furthermore, some of the most successful films in recent years have been based on science fiction stories.It is often thought that science fiction is a fairly new development in literature, but it can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society, a theme which is still often found in modern stories.Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verne and H.G. Wells, to mention just two well-knownauthors, have been translated into many languages. Modern science fiction writers don't write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future world which are a reflection of the world which we live in now. Because of this their writing has obviously political undertones.In an age where science fact frequently overtakes science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology.Which of the following statements can't prove that science fiction is very popular today 查看材料A.Hundreds of titles are published every year.B.All kinds of people love it.C.Some of the most successful films of recent years have been based on science fiction stories.D.Science fiction can be found in books written hundreds of years ago.
