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

5

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. 24. 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.

25. 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.

26. 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

27. 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

Like people, plants experience stress. And also, like people, the response to that stress can determine success.

Bad environmental conditions, such as drought, flood, heat and other stresses, affect yields(产量 ) more than crop pests and diseases. We are trying to find a way to equip plants with the ability to tolerate(忍受) environmental stress and maintain(保持) high yields（产量）, said Stephen Howell, a professor of genetics and cell biology.

Plant cells produce proteins（蛋白质) and ship them to different parts of the cell. Under normal conditions, these proteins are folded（合拢） into their normal, healthy structures as they are produced. When a plant is under stress, its cells produce poorly folded or unfolded展开的 proteins. Then a built-in system senses this and “sets off an alarm in the cell,” said Howell.

In response to the alarm警报, another protein (IRE1) starts working and creates a different process which activates (激活) the stress response genes whose products bring about defensive measures that help the plant survive.

“As it turns out, responses that are activated（被激活的）under stress conditions actually inhibit the growth of plants,” said Howell. “This allows them to reserve their energy to survive the stress conditions.”

For plants in the wild, this response is a help for survival, he said. In production of agriculture crops, however, this response reduces yields.

“You don’t want crop plants to stop growing,” Howell said. “You want them to continue to grow and produce even though they are under stress.”

With the new understanding of this stress response, the next step may be to silence the alarm system, said Howell. “What may be important is to disable some of these stress responses. That may make the plant more productive under stress conditions.”

28. According to the text, an alarm in the plant cells is caused by . A. the folded proteins B. the changed proteins C. the defensive measures D. the stress response genes

29. The energy reserved in the plants under stress conditions . A. helps the plants to survive B. helps to maintain high yields C. keeps the plants growing D. helps to produce proteins

30. The underlined word “inhibit” in Paragraph 5 can be replaced by “_. ”.

7

A. prevent B. start C. continue D. help 31. How does Howell intend to make crop plants maintain high yields under stress conditions?

A. By making crop plants keep more energy. B. By making crop plants stop growing. C. By making the alarm system stop working. D. By making the alarm system respond quickly.

“Cleverness is a gift while kindness is a choice. Gifts are easy –they’re given after all. Choices can be hard.” –– Jeff Bezos.

I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I’d never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I’d been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t, and I wasn’t sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I’d always wanted to be an inventor, and she wanted me to follow my passion.

I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn’t already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but ultimately (最后), I decided I had to give it a shot. I didn’ t think I’d regret trying and failing. And I suspected I would always be haunted by a decision to not try at all. 8
