Unit 7 Will people have robots? Reading PracticeA.A kind of little cars may some day take the place of today’s cars. If everyone drives such cars in the future，there will be less pollution in the car. There will also be more space for parking cars in cities，and the streets will be less crowded. Three such cars can fit in the space now needed for one car of the usual size.The little cars will cost much less to own and to drive. Driving will be safer, too, as these little cars can go only 65 kilometers an hour. The cars of the future will be fine for getting around a city, but they will not be useful for long trips. Little cars will go 450 kilometers before needing a stop for more gas.If big cars are still used along with the small ones，two sets of roads will be needed in the future. Some roads will be used for the big，fast cars and other roads will be needed for the slower，small ones.41. There is much pollution in the car today because________.A. people drive big carsB. people drive little carsC. the cars go 65 kilometers an hourD. the cars can go 450 kilometers an hour42. The usual size of cars today are ______that of future cars.A. much smaller thanB. much the same asC. three times as large asD. a little larger than43. We can learn from the passage that________.A. big cars cost less to own and to driveB. big cars are not useful for long tripsC. the cars of the future will be much smaller than today’s carsD. small cars are faster than big ones44. The street will be less crowded because______.A. there will be fewer cars in the futureB. there will be fewer passengers in the streetC. driving future cars will be safeD. future cars will be much smaller45. Two sets of roads may be needed in the future because ______.A. there will be too many cars in the futureB. more and more people will get around a cityC. big cars and little cars may be used along with each otherD. it looks more beautiful to have two sets of roadsB. Driving Down PM 2.5We know that driving less reduces (减少) air pollution. But there’s another way to help out: drive green cars.Green here means new energy (能源). There are mainly three types of green cars: pure-electric (纯电动的) cars, hybrid (混合动力的) electric cars and fuel cell (燃料电池) cars.These cars either use less gas (天然气), or no gas at all. Fuel cell cars use hydrogen (氢), while electric cars use electric as its energy source. They produce less air pollution.You have probably seen them in the street. Last year, almost 28,000 new energy cars wee sold and 80 percent of them were buses, China Radio International reported.On Nov 26, China announced (宣布)that 28 cities and regions will promote (推广)the use of green cars. If a person buys a new energy car, the government will give him or her some money back. But still, many people don’t want green cars. Green cars need to charge (充电) regularly. It takes one and a half hours to charge an electric car, but this only allows the car to drive 200km,according to China International Business magazine. Also, you can’t charge green cars at home. You have to drive them to a special charging station.But, think about the air pollution. Maybe the trouble is worth (值得) it.“Our ministry’s two electric cars are very popular. My colleagues (同事) are more willing (愿意) to take them, because every kilometer they travel means a reduction in PM 2.5 emissions,” said Wan Gang, minister of science and technology.1.What ways can reduce air pollution?_______________________________________________________________________________ 2.How many types of green care are there now?_______________________________________________________________________________ 3.Will you get some money from the government if you buy a green car in China?_______________________________________________________________________________ 4.Why do many people not want green cars?_______________________________________________________________________________ 5.How long does it take to charge an electric ar?_______________________________________________________________________________C.People use money to buy food, books and hundreds of other things they need. When they work, they usually get paid in money.Most of the money used today is made of metal or paper. But in the time long ago, people used to use all kinds of things as money. One of the first kinds of money was shells(贝壳).In China, cloth and knives were used as money. Elephant tusks (牙), monkey tail and salt were used in some parts of the world. Rice was also a kind of money used by the people in some islands. Some animals were used as money, too.The first copper coins(硬币) were made in China. They were round and had a square hole in the center. Different countries have used different metals for their money. Later, some countries began to make coins of gold and silver (银). But gold and silver were heavy to carry when people needed a lot of coins to buy something expensive. The Chinese were the first to use paper money. The first paper money looked more like a note from one person to another than the paper money used today.Money has had an interesting story from the days of shell money till today.46.

Always Read the Full StoryA young woman in her 20s was sitting on the train, next to her mother. They both look tired but excited. The young woman was looking out from the train’s window. Suddenly, she shouted, “Mom, look, the trees are behind us!” Her voice was so loud that everyone on the train heard. Mom smiled. But a young couple sitting nearby looked at the young woman’s childish behavior with pity. “Poor young woman. There must be something wrong with her mind,” they thought.A while later, the young woman shouted again,“Mom, look! The clous are running with us!”Mom smiled again. And she seemed very happy with the young woman’s words.Finally, the couple couldn’t help asking the old woman, “Sorry if we offend (冒犯) you. But why don’t you take your daughter to a good doctor?”The old woman smiled and said, “Actually, we have just come from the hospital.”“Then you should go to a better one. Because it seems that your daughter’s situation (情况) hasn’t improved,” said one of them. They felt so bad for the old woman.“No, in fact I’m very happy with the treatment (治疗),” said the mother. “My daughter was blind (失明的) from birth. Today, she is seeing the world for the first time.”Every single person has a story. Don’t judge (评判) people before you truly know them.

Read and learn about space station and astronautsOne night, you are taking a walk in your neighborhood. Suddenly, you see a star-like thing flying across the sky. What do you think it could be? A plane? A meteor (流星)? These can be true. But there could be another answer: the International Space Station (国际空间站), the third brightest object (物体) in the sky.The ISS is a spaceship. It flies around the earth every 93 minutes. It is also a science lab (实验室). Five space agencies (航天局) --- the US, Russia, Canada, Europe and Japan---worked together to build it. More than 200 astronauts and scientists from 15 countries have visited the space station. The first piece of the ISS is launched in November 1998 by Russia. This year is the 15th year ofthis launch.The ISS is very big. It is nearly as big as a soccer field and larger than a six-bedroom house. There are many different parts in the ISS, including (包括) labs, modules (舱) and solar panels (太阳能板). These make the ISS very heavy. It is about 450 tons. That’s the same weight as 320 cars.ISS is home to astronauts. Usually, there are three to six of them on board. Astronauts on board () do many science experiments in biology (生物) and physics. They also study what happens to the human body when people live in microgravity (微重力) for a long time.Although the ISS is in space, it is important to humans back down on the earth. The ISS helps to observe () the earth’s ecosystems () and warn earthquakes (). As for children, the ISS is a great tool (工具) for education. Children can ask astronauts in the ISS any questions with the help of satellites (). For example, what do you eat? How do you sleep? This is a good way to improve children’s interest in science and technology.Q & A abut astronaut’s livesQ: How do astronauts feel in space?A: With microgravity, astronauts feel “weightless”. It is similar when you are on a roller coaster () when it starts to go down. Astronauts feel that they keep falling, but never come to a stop.Q: What do astronauts eat and drink?A: Without little gravity, food pieces will move everywhere in the ISS. So astronauts have to eat freeze-dried (冻干的) food. Drinks, such as coffee and cold drinks, come as powder (粉末). They are kept in plastic bags with straws (吸管). Astronauts need to add water to drink it.Q: What happens t your muscles (肌肉) in space?A: There is little gravity, so almost no physical effort is needed in standing up or sitting down. As a result, muscles become very weak. That is why astronauts exercise two hours per day. Treadmills (跑步机) and bicycles are most commonly used in the ISS.Q: How do astronauts wash themselves?A: Like what we do on the earth, astronauts also need to wash their hair and brush their teeth. However, they wash their hair with rinse-free shampoo (免洗洗发露). Brushing teeth needs special care. When they get a mouthful of toothpaste (牙膏), they have to either swallow (吞) it or spit it into a washcloth(毛巾). Don’t worry. The toothpaste for astronauts is safe to eat.Summary(总结): Useful words, phrases and sentences you learned from these passages_______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________。
