How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic（基因的）tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.
“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.
“Every ache and pain,” Smith suggested, could be understood as “the beginning of the end.”“That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”
Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was“no significant difference”between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.

查看习题详情和答案>>Dear Editor,
I have just returned home after studying for a year in Germany. But it seems that my parents don’t understand me now. They expect me to be the same person I was before I went abroad, but I’m not! Why can’t they let me be myself?
Jimmy
Hi, Jimmy,
As far as I know, people who have lived abroad often find that the adjustment （调整） to returning home is more difficult than their adjustment to living in a foreign culture. Why? We expect to have some problems when we go to a new place, speak a different language and learn the rules of a different culture ... But home? ... we know that place!
Your parents expect that the same person who boarded the airplane one year ago will be returning. Especially if they have never been abroad themselves, your parents probably won’t understand the changes that living abroad can cause in a person. On the other hand, you may have maintained (保持) an ideal mental image of your loved ones while abroad, an image that is broken into pieces when you return.
Remember you have been living a different lifestyle in your host country, and you have probably become very independent while staying there alone. Now that you’re home, you will be expected to conform （顺应） again to the lifestyle of your family. As a result, you may be upset about your parents’ involvement in your life.
Communication is the key to overcoming this problem. Tell your parents how you are feeling. Share with them information about cultural re-entry（重归）, and ask them to be patient. This does not mean that you have to forget your experience and give up everything you’ve learned! Learn to find a balance between the old and new, just as you did when first adjusting to your host country’s culture.
1.What is Jimmy’s main purpose in writing the letter?
A．To criticize his parents.
B．To ask for advice about his studies.
C．To complain about his parents.
D．To ask for help.
2.What does the editor think of Jimmy’s problem?
A．It’s unusual. B．It’s normal. C．It’s serious. D．It’s interesting.
3.The editor thinks that both Jimmy and his parents ______.
A．have changed in the past year
B．have unrealistic expectations of each other
C．need to behave like they did before
D．need to find a balance between the good and bad
4.The author suggests that ______ would help solve Jimmy’s problem.
A．patience and trust
B．patience and politeness
C．better communication between family members
D．a deeper understanding of the host country’s culture

B
The worst danger is a house on fire when people are asleep. Always be ready to leave through a window into the garden by making sure you can open it if necessary. If you should be on holiday in a tall building or hotel, make sure you know where the fire escape(太平梯) is. When you can’t find any way out, try to find pieces of cloth and make a rope to get out of a window to safety. If you smell burning in your home, get out right away. If you can’t breathe properly because of smoke on your way out, crawl(爬) on your hands and knees because smoke rises and the air will be cleaner near the floor. Smoke is a killer and more people die from breathing it in than actually being burned.
Fire in a cinema hall or public place often means people pushing to reach a door. Keep your head up with arms up in front of your chest. This protects your chest and gives you the best chance to breathe. Above all, don’t get frightened!
