B

Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his now place and meet his friends.

My earliest memories of my father are of a tall, handsome, successful man devoted to his work and family but uncomfortable with his children. As a child I loved him; as a school girl and young adult(成年人)，I feared him and felt bitter about him. He seemed unhappy with me unless I got straight A’s and unhappy with my boy friends if their fathers were not as“successful”as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.

　 On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor cafe. We walked along that afternoon, did some shopping, at each the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical(挑剔的)air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?

　 The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closet to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad in his new home in Arizona is back to me from where he was. ( 08江西卷)

第5 天　　　　　　　　　　　　　　　　 　A

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.

　　 When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered(转基因的) trees.

　　 Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.

　　 Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.

　　 Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.

　　 The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack..

　　 So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes(基因组).

　　 However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.

"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."

　　 But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.

　　 They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.
