Unit 4 Space Exploration单元测试第一部分阅读（共两节，满分50分）第一节（共15小题；每小题2.5分，满分37.5分）AIt's 2035. You have a job, a family and you're about 40 years old! Welcome to your future life.Getting ready for work, you pause in front of the mirror. “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics (智能电子元件) are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe you're 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You're not even middle-aged!As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear, “To lose weight, you shouldn't eat that!” from your shoes. They read the tiny electronic code(电子源码)on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible foods appears on the counter as the kitchen checks its food supplies.“Ready for your trip to space?” you ask your son and daughter. In 2015 only specially trained astronauts went into space—and very few of them. Today anyone can go to space for day trips or longer vacations. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor says you need these for space travel.” Thanks to medical advances, vaccination shots (防疫针) are a thing of the past. Ordinary foods contain special vaccines. With the strawberries in their mouths, the kids head for the front door.It's time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot,” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your enewspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.1.

In particular areas machines have superhuman performance, but in terms of general intelligence they're not even close to a rat,” he explained.Oren Etzioni, an Israeli scientist, said, “There's a brand of science fiction(小说) that's very dystopian(反面乌托邦的). These works of fiction talk about how the world is going to get much worse. I'm too much of an optimist (乐观者)to get a lot of pleasure out of reading such stories.”However, robots are becoming smarter. Indeed, our homes are becoming more intelligent when we place devices (设备) like the Amazon Echo and Google Home on our kitchen counter. But, at least for the moment anyway, we shouldn't feel intimidated by this artificial intelligence.There are robots that move like animals and robots that offer guidance. There's even a robot that can paint a picture of Einstein and a robot that can fold your laundry. Robots are not taking over the world yet. So for now, we can simply sit back and relax. And have a robot waiter pour us a drink.5. What does the dialogue at the beginning of the text tell us?A. Robots aren't as smart as we expect.B. It isn't easy to forecast the weather correctly.C. A speaker may be misunderstood by another.D. Weather is a good subject to start a conversation.6. What do the scientists think about the artificially intelligent robots now?A. They have superhuman performance in kitchen tasks.B. They have the common sense of a 5yearold.C. They can only learn the basic things of humans.D. They are still poor at general intelligence.7. How did Oren find the dystopian science fiction?A. Pleasant.B. Typical.C. Realistic.D. Controversial.8. What does the underlined word “intimidated” mean?A. Comforted.B．Astonished.C. ThreatenedD. Disappointed.CMy husband and I recently went to Disney World with our children and grandchildren. Our grandchildren were excited about the attraction where they can drive the cars. Since our party was uneven in numbers and two people fit in each car, I sat out that one and headed down to take pictures of them.As I waited for them to drive by, I noticed a car with a father and his son who looked to be about 7. They rolled down the hill, and then as they neared where I sat, the car shook a few times and then stopped.The young driver looked frightened, “I can't do it.”His father quietly said, “Yes, you can.”“No, I can't!”“Yes, you can.”The little boy was almost in tears, “I CAN'T!”With deep patience, the father said, “Son, you can do this. I'm going to help you.”Then he talked him through starting the car. And moments later with the father helping his son, the two went smoothly on their way down the track.The scene brought tears to my eyes because I couldn't imagine how many times my father had to do that with me. Every time things got hard or when I had failures along the way, I'd say, “I can't do it.” He'd reply, “You can.” Time and time again he patiently encouraged me on the journey. And just like that little boy's dad, my sweet father would say, “Michelle, you can do this. I'm going to help you.”That's where the true strength comes in. I can't do things under my own power, but when my father comes beside me and provides wisdom(智慧) and strength, there's no way I can fail.9. Why didn't the author join others in driving the cars?A. Her family could drive except her.B. Her family fit in the cars without her.C. She was attracted by something else.D. She wanted to take photos of her family.10. What made the 7yearold son frightened?A. He got the car to leave the track.B. He failed to drive the car well.C. He rolled too fast down the way.D. He just couldn't get the car started.11. How did the father help his son?A. By forcing him to drive bravely.B. By praising him for his efforts.C. By encouraging him patiently.D. By starting the car himself.12. What's the author's tone in writing the text?A. Confused.B. Humorous.C. Concerned.D. Grateful.DEvery year you collect a large amount of junk. Think about Christmas presents, birthday presents and holiday souvenirs, and the list goes on. Where does it all end up? Well, if you don't throw it out, it goes to the basement(地下室).However, things with huge amounts of value might be buried in those unwanted gifts. Perhaps there's a beautiful crystal boat in a bottle that was made just long enough ago to be worth a large amount of money. Or, maybe it's an old board game that was never used and has now become a collectable. Yes, these items can be your ticket to a hidden treasure, and all you need to do is go hunting.Once you find the items, you'll probably be wondering how to sell them. Most people choose the standard yard sale and this, of course, is a mistake. You won't find the collectors by this type of sale. Instead, you need to reach the widest audience possible. The answer? eBay.With eBay, you can gain a large amount of attention, start an auction(拍卖) and get selling. Of course, before you can do this, you have to set yourself up as a trusted seller. You can do that quite simply by buying a few small, cheap items first. This will raise the rating(等级) of your little online shop. After that, you should have no trouble at all attracting buyers.Of course, this can just be the beginning. Once you know how to sell things online, you can start making a lot more money by investing and reselling. It's a great choice for a second income.13. According to the text, the gifts we get every year ________.A. are a waste of moneyB. can be valuable sometimesC. should go to yard salesD. should be kept in a safe place14. Why does the author suggest selling your things on eBay?A. It's designed for collectors.B. It follows official standards.C. It has a much larger audience.D. It seldom makes any mistakes.15. What do you have to do before selling things on eBay?A. Gain public attention.B. Buy some expensive things.C. Attend several local auctions.D. Raise your shop's credit rating.第二节(共5小题；每小题2.5分，满分12.5分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
