But he wont set off when it is raining.答案与解析Were由句意可知非真实条件从句表示将来不行能实现的事情，且be后有to故从句谓语动词的形式为“were to动词原形”，该空填were。9If the present unemployment_continue, the society would face a more difficult situation.答案与解析should这是一个虚拟条件句，表示与将来事实相反，从句动词形式是“should动词原形”。10He was very busy yesterday; otherwise, he _ (come) to the meeting.答案与解析would/could/might/should have come句意：昨天他很忙，否则他会来开会的。otherwise经常搭配虚拟语气，表示与过去事实相反；he was busy yesterday是过去真实的状况，没有用虚拟。语 篇 提 能.阅读理解ALast 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 new 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 I feared him and felt bitter about him. He seemed unhappy with me unless I got straight As and unhappy with my boyfriends 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 fathers friends for lunch at an outdoor care. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my sons funny facial expressions. Gone was my fathers 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 closer to him at that moment. After so many years, Im at last seeing another side of my father.

It is also called biological engineering (生物工程), which is drawing more and more attention now. Sometimes its a hot topic discussed by people.The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these_two_killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only can these two diseases be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span can be prolonged (延长)Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary (遗传性的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. Scientists just need to find the wrong gene and correct it, and a healthy child will be born.Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in a very normal way. Of course, the governments must take care to control gene technology.5What does “these two killers” in the second paragraph refer to?A. Gene technology and another treatment of the two diseases.B.

Gene technology helps people with hereditary diseases to live longer.B. Using gene technology, scientists find the wrong gene and correct it.C. Using gene technology, human babies can be cloned.D.

One advantage of city life is that everything you need is so closely at hand. Living beside the subway station means I dont need the car to get around, what saves me money. Also, there are shopping centres and museum everywhere. However, like other big cities, London have its own problems. Londoners dont chat on the train and the bus, and neither they offer help to each other. I think living in London will be much better were there not so much noise or pollution. But a famous poet who once said, “If you are tired of London, you are tired of life.” Im never tired of London!答案My name is Stephen and I in London.
