We often wonder what the world would be like in a hundred years’ time.‎ Thinking of space, perhaps a permanent(永久旳) station on the moon will have been set up. Perhaps people will be able to visit the moon as tourists. Cheap rockets for space travel will have been developed, permitting long journeys throughout the solar system(太阳系). When that time comes, people will be taking holidays in space and visiting other planets. Great progress will have been made in medicine, too. Perhaps a cure will have been discovered for the most terrible of all ‎ diseases(疾病)—cancer. Pollution is a problem we must solve. In a hundred years’ time it will have been controlled.‎ The world will have been developed—even Antarctica. There will be large cities in Antarctica. We already have supersonic (超音速旳) flight, but in a hundred years’ time we will have supersonic land travel as well.‎ We will have used up most of earth’s land to build our cities, so floating cities will have been built. The Japanese already have plans for cities of this kind. And there will be cities under the sea. The first of these will have been completed.‎ ‎( ) 56.

I chose this job so I could travel the world, but the job has taught me many unforgettable lessons. The work is sometimes difficult. I have seen famines, wars, earthquakes, poverty and death. But I have also seen courage, hope and happiness.‎ In India, I visited a city where there were many homeless children. Some were as young as four years old. They lived in the streets and survived by begging or stealing. But then a wonderful lady called Rosa opened a home for them. Within one year, she was looking after two hundred children. She clothed them, fed them, and taught them. She gave them hope.‎ Another time, I was in Turkey after a terrible earthquake. In one place, I found an old lady whose house was in ruins, her son was missing and rescuer workers said there was no chance that he was still alive. But the old lady did not give up hope.‎ ‎ For four days, she moved heavy stones one at a time by herself. She did not stop until she found her son. He was alive.‎ Here in China, I met a young boy with a serious condition. He had undergone twenty operations and spent nearly his whole life in hospital. I thought he would be sad, but when I met him, his smile was so warm and welcoming.‎ In life, we need role models that we can admire and learn from. When my life is difficult, I try to remember the courage and goodness of these three people.‎ ‎( ) 59.

Their luck.‎ C A Shoe Pattern Harry is eighteen now. He studies in a middle school. His parents like him very much and hope he can become a famous man. So they often tell him to study hard and they do all for him. They call him at six in the morning, after breakfast his father takes him to school in a car and in the afternoon, as soon as the young man comes back, the supper is ready. Of course, he never washes his clothes or goes to buy something in the shops.‎ Once Harry’s father was sent to London on business. He would stay there for half a year. Leaving, he told his wife to take good care of their son. The woman had to get up earlier and did all that her husband did before. And two months later ‎ she was so tired that she was ill in bed. Now the young man got into trouble. He couldn’t do any housework. He had to do as his mother told him. Even he didn’t know where to get on the bus!‎ Yesterday Harry’s mother found his shoes were worn out and told him to buy a new pair in the shop. But he didn’t know how to choose. The woman had a sigh and gave him a shoe pattern and told him to buy a pair of shoes himself. It’s Saturday today and Harry doesn’t go to school. With a policeman’s help, he found a shop. The shopkeeper was friendly to him. The man brought a lot of shoes and asked him to choose. When he was trying on a pair, suddenly he remembered something and took them off. The man was surprised and asked, “What’s the matter, young man?”‎ ‎“I’m sorry, I’ve left the shoe pattern at home!”‎ ‎( ) 63. Harry’s parents do all instead of him because _______.‎ A. he’s too young ‎ B. he has poor health C. he’s busy with his studies ‎ D. they hope he spends all time on studies ‎( ) 64. The woman had to look after her son by herself because _______.‎ A. her husband wasn’t at home B. she was stronger than her husband C. she knew the young man well D. she was freer than her husband ‎( ) 65. When the man was in London, _______.‎ A. Harry had to stay at home B. Harry didn’t find the bus stop C. Harry fell behind in his class D. Harry wouldn’t go to school ‎( ) 66. The woman told her son to buy a pair of shoes because _______.‎ A. she didn’t know what kind he needed B. she was busy with the housework C. something was wrong with her D. she wanted her son to do something himself ‎( ) 67.In fact, _______.‎ A. Harry wanted his mother to buy shoes for him B. Harry should believe in himself and be on his own C. Harry wouldn’t listen to his mother D. Harry was strong enough to buy shoes for himself D When Cathleen Gardiner’s twins were born 17 years ago, doctors told her that they were a pair in a million. One had Down syndrome(低能综合症), while the other did not. Here, Cathleen tells their touching story.‎ Since Sean was born 17 years ago, I have always thought that he is just as wonderful as his brother and sister. Though he had a disability(残疾), we have never viewed him as a burden. He has always been a blessing. The doctors explained that though they were twins, they came from two different eggs. Lisa could walk at 11 months old, while Sean didn’t take his first steps till he was three. By two, Lisa was talking a lot, but Sean wasn’t able to speak until he was nearly four.‎ For the first five years of his life, Sean needed a great deal of care. Looking after him was my full-time job, though I also worked as a technical adviser in a computing company. We never treated them differently. We gave them the same toys and spoke to them in the same way. We encouraged Sean to keep up with Lisa, even though he never could, and we would help him develop his abilities. We sent them to the same primary school even after doctors advised us that Sean should go to a school for the disabled.‎ We had to explain to Lisa that he wouldn’t learn as quickly as she would. She told us that she’d help him with his school work. Having a non-disabled twin has really helped Sean develop. The love they share has given him a great deal of support. Now Sean and Lisa are both about to finish high school. I don’t think he would have done nearly as well today without Lisa’s help.‎ ‎( ) 68. How many children does Mrs. Gardiner have at least?‎ A. Two. B. Three. C. Four. D. One.‎ ‎( ) 69. The third paragraph mainly tells us that _______.‎ A. the couple treated the twins equally B. Cathleen did all she could to look after Sean C. the couple didn’t follow the doctor’s advice D. the couple encouraged Sean to grow up ‎( ) 70. This passage tells us that _________.‎ A. love can do wonders ‎ B. nobody is foolish or clever C. being stupid doesn’t matter ‎ D. all men are born equal 第二节（共5小题；每小题2分；满分10分）根据短文内容，从短文后旳选项中选出能填入空白处旳最佳选项.选项中有两项为多余选项.‎ Taking good notes is a time-saving skill that will help you to become a batter student in several ways 71 Second, your notes are excellent materials to refer to when you are studying for a test.
