In America, when people say “man’s best friend”, they don’t mean another person. Instead, they are talking about a lovely animal:A dog! These words show the friendship between people and animals. Dogs and other pets can give happiness to people’s lives. Some people regard their pets as their children. A few even leave all their money to their pets when they die!

   Animals can help people, too. Dogs can be taught to become the “eyes” for a blind person or “ears” for a deaf people. Scientists have found that pets help people live longer! They make people happier, too. Because of that, animals are brought into hospitals for “visit”.

   Americans hold “Be---Kind-to-Animals Week” in the first week of May. Pets shows are held during the week. Even if you don’t live in America, you, too, can do this. How? First, think about how animals make your life richer. If you have a pet, take more time this week to play with it. Remember to give it delicious food. Also, be sure to keep your pet from those unwanted babies.

   f you don’t have a pet, be kind to animals around you. For example, if you see a street dog, don’t kick it or throw things at it. Instead, just leave it alone, or better yet, make friends with it. If others around you do bad things to an animal, try to stop them. As people, we must protect animals who can’t speak for themselves.

A.The great impact and progress in genetic engineering

         B.Worries about privacy protection

         C.Worries about medical use of genetic engineering

         D.Genetic knowledge helps to predict diseases

         E.Genetic knowledge may not be properly used

         AB.The application of genetic engineering in the medical fields

 

1.__________

Current research into the human gene system is helping us understand why people have predispositions(易患某病倾向)to certain diseases.Knowing our genetic makeup can help us to judge whether or not we may be stricken by particular illness, such as cancer.Even before birth, we are able to do genetic screenings to determine what a child's genetic disorder will be.Scientists have already isolated and identified the genes responsible for the more than 4,000 genetic diseases that affect human beings.

2.__________

The implications of this knowledge are astonishing. In addition to predicting genetic predisposition towards diseases, gene therapies may provide new treatments or cures for serious diseases.Millions of people already use genetically engineered drugs to treat heart disease, cancer, AIDS, and strokes (中风). But with the research that is now being conducted, we may find cures to many more diseases.In the near future, genetic experimentation will also allow parents to select the traits of their children. Genetic traits that determine height, weight, eye and hair color will be able to be controlled, and many parents are excited about this potential.

3.__________

Many people, however, are unwilling to accept the possibilities genetic research allowsFor example, one reason some women do not use the largest genetic testing for breast cancer is because they are afraid they will be discriminated against.Another problem is that many people do not want to discover their weakness.What if they learn that they have a disease for which there are no medical cures? How will such knowledge affect their lives? Do people really want to know what they will die of?

4.__________

Many people believe that history has not always shown human decision-making to be bright when it comes to ethical(道德的)choices. Jeremy Rifkin is probably the most well known opponent of genetic engineering. He believes that humans are not responsible enough to experiment with genes and should not “play God” He asks, “Just because it can be done, does that mean it should be done?” He points out that our society will eventually look and act the same if parents select the traits of their children, and he questions the desirability of such a society.

5..__________

One of the fears expressed about genetic experimentation involves privacy. Already blood sample taken from patients in hospitals have been used for genetic research without the patients’ permission. Most people would agree that one’s health and genetic makeup are private concerns. But if insurance companies gain access to this information, it could have a large impact on insurance coverage or costs; if employers gain access to the information, it could have a large impact on hiring or promotion decisions. The possibilities for discrimination are obvious.
