They think it is very exciting and has more fun. But in fact, it is not good. Making vacation plans is very important.First, a vacation plan can make sure that everything goes well. If you visit a place but you don't book a hotel, you may have no place to stay at night.Second, you have lots of things to take with you for a vacation. You need to plan what things you have to buy and what things you need to put in bags. For example, you want to visit one place, but when you arrive at the airport(机场), you forget to bring your plane ticket! You may be late for the plane.Third, making a vacation plan can help you save a lot of money. No one wants to spend more money than they want to. If you surf the Internet before you go on a vacation, you may find some cheap plane tickets and hotel rooms.Next time when you go on a vacation, try to write down some plans. They can help you have more fun in your vacation.(1)The writer thinks that taking a trip with no plans is ______.A.interesting B.relaxing C.bad D.exciting(2)From this passage we can know it's very important to ______.A.make a vacation planB.take a trip by planeC.surf the InternetD.visit a place with more money(3)______ can make sure that everything goes well during the vacation.A.Bringing your plane ticketB.ooking a cheap hotel roomC.Taking many things with youD.Making a vacation plan(4)The underlined word "book" in the passage means "______" in Chinese.A.装修 B.预订 C.扩建 D.推荐(5)The passage mainly tells us ______.A.why we must make a vacation planB.it's important to have more funC.how we can make a vacation planD.what we must take during the vacationMost people work or study from Monday to Friday. The weekend is usually a time of rest. Today's Chinese teenagers can hardly rest during the weekend.According to a survey, 24% of the Grade 8 students in Beijing have classes at the weekend. Over 40% of the middle school students have less than eight hours' sleep each night because of study. And this isn't only in Beijing. Ji Chunying is a Grade 9 student in Guangzhou. The 14-year-old girl has to get up at 6:45 am on Saturday. Then she has a whole day of classes. On Sunday, she goes to extra classes for maths and physics. But Ji doesn't complain. She says her classmates all work very hard.However, some students are much luckier. They don't have to go to school on weekends. Ding Yi, a Grade 8 student from Jinan, Shandong, is one of them. And she's a top student. During the weekend, Ding usually gets up at 8 am. Then she spends some time doing homework. After that she is free to go shopping or watch TV.Ding said her mother once wanted her to try extra classes. But when they asked Ding's teacher about it, the teacher said it was unnecessary. "My teacher said I didn't need to push myself too much. Learning well at school is enough," Ding said. "I feel pretty lucky."(1)Over 40% of the middle school students have less than eight hours' sleep each night because of ______.A.playing computer games B.playing with friends C.busy study D.watching TV(2)How many students are mentioned in this passage?A.2 B.3 C.4 D.5(3)We can learn from the passage that ______.A.some middle school students can enjoy their weekendsB.all the students in China are busy studying on the weekendC.every student in China has to go to extra classes on the weekendD.all the students complain about their busy weekends(4)What does the underlined word "extra" mean in Chinese in this passage?A.额外的 B.非常的 C.特别的 D.特大的(5)The passage may be a ______.A.story of science B.school notice(通知) C.short play D.news report

Next time you’re filling up the cavernous fuel tank of the gas-gulping family jalopy, imagine getting 230 miles per gallon. Better yet, how about never buying another gallon of gas After years o hope and hype, electron-powered driving finally appears to be on the verge of reality. In the next three years, at least a dozen pure electric or plug-in hybrid cars are slated to hit the market in the U. S. Electricity-driven vehicles from giants such as General Motors Co. and Nissan Motor Co., as well as start-ups like Fisker Automotive Inc. in Irvine, will provide consumers with a wide variety of choices. These new vehicles promise to combine blinding fuel efficiency, radical new technology and futuristic styling that makes the hybrid Toyota Prius look downright staid. Battery makers and automakers alike are tooling up factories to produce big volumes of electric vehicles. Meanwhile, power utilities and regulators are scrambling to figure out just how big the market will be. "This is happening and it’s happening soon," said Mark Duvall, director of electric transportation at the Electric Power Research Institute, an independent, nonprofit research group. "By the end of 2011, consumers will have more choices in vehicles they can plug in than they currently do for hybrids. ’ The electric vehicles will be arriving at a good time. With gasoline prices creeping up once again and federal regulations calling for huge fuel economy gains in the next half-decade, there’s increasing demand for cars that burn less fuel, make less noise and push automotive technology forward. In August, President Obama set a national goal o getting I million plug-in vehicles on the road by 2015. It took about twice as long to get a million hybrids rolling on U.S. streets and highways. But any new technology that involves high-voltage, exotic battery chemistries and 3,500-pound objects hurtling forward at high speed is bound to hit some potholes. Early adopters, experts say, will have to contend with charging infrastructure challenges and some pretty long waiting lists. And did we mention price Even the least expensive electric or plug-in car will cost more than 25,000, and most will come in closer to twice that. "There will be some real challenges at first," said Roland Hwang, vehicle policy director at the Natural Resources Defense Council. "These are going to cost more than conventional cars. The infrastructure is not going to take care of itself. These issues will determine whether this is a trickle or a massive flood." Restarting electrics Electric cars are hardly new. In fact, a century ago, around .the time of the dawn of the automobile, there were as many electric as gasoline-powered cars. But technological limitations eventually killed those early EV, and electric cars didn’t truly raise their heads again until the late 1990s. That’s when a smattering of electrics, including the much-lamented GM EV1, was made available in California as part of a government-mandated test program. Wildly popular among a select group of enthusiasts, they were officially declared unfeasible and unprofitable by automakers. Today, only a few hundred are still on the road, among them a Toyota RAV4 EV driven by Paul Scott, co-founder of electric vehicle activist group Plug In America. Nobody was happier than Scott when Tesla Motors Inc.. a San Carlos, Calif. , automaker, last year began selling its all-electric Roadster, a rocket of a two-seater that noiselessly goes from zero to 60 mph in less than four seconds. True, the Roadster costs 109,000. And it has a waiting list longer than Sunset Boulevard. But to people like Scott, its arrival signaled the coming of a new electric era. "This time electric cars are here to stay," said Scott, who envisions charging cars using solar power, making them essentially cost-free to operate. Tesla and other nimble start-ups have helped jump-start the industry. Now big automakers are getting their electric programs in gear. That’s no minor development considering the titanic capital costs involved in developing high-volume-production vehicles. For Ford Motor Co. , better batteries were key. Previous technologies were just too heavy and inefficient, said Nancy Gioia, the automaker’s director of global electrification. "They weren’t ready for mass production," she said.But in the last couple of years, huge improvements and new battery chemistries "opened the opportunity" for ambitious product plans, she said. Gioia predicts that as many as a quarter of new vehicles sold by 2020 will be electrics, plug-in hybrids or traditional hybrids. Challenges ahead Yet even the fiercest electric advocates admit that battery reliability still has room for improvement. Arthur Krieger, a retired police officer in Los Angeles, drives a Prius powered by a relatively small nickel metal hydride battery to assist the gasoline engine. Tile battery needed replacement after nine years on the road. That’s when Krieger got a nasty surprise: A new one would cost more than 4,800. "That cost will wipe out the entire cost savings of having a hybrid in the first place." Krieger said. The price would be even higher on an all-electric vehicle using the latest chemistry., lithium ion. Already widely used in cell phones, watches and laptops, those batteries have storage, charging and weight characteristics that make them superior to previous technologies―with premium prices to match. A replacement battery for a Tesla Roadster costs 30,000, and it can move the car only 200 or so miles before it needs to be recharged. That’s a 3.5-hour process on a high-powered charger, 30 hours on regular household current. Then there is the matter of exactly where to re-juice all those electrics. Some experts believe that public charging stations will be the best solution, either those put up by state and local governments or, perhaps, private for-profit companies. At present there is almost no such infrastructure. Building a nationwide network would cost tens of billions of dollars. That means most electric owners will be charging at home initially. Plugin hybrids, which primarily run on batteries but also have gasoline-powered engines to supplement range and power, can get by on standard household current. They’re ready to roll in five or six hours. All-electric cars, however, can take well over a day to charge unless owners invest thousands of dollars in home electrical upgrades. A rewarding experience For those willing (and able) to take the plunge, however, the rewards of owning electrified cars could include the financial kind. Thanks to a provision in last year’s 700-billion Wall Street bailout legislation, buyers of electric or plug-in hybrid cars can qualify for a tax credit of as much as 7,500. Routine maintenance could be a bargain too. Since these vehicles use simple electric motors rather than complex gasoline or diesel engines, as well as pared-down or in some cases nonexistent transmissions, they are far easier to service than conventional vehicles. There’s no oil to change, no radiator to flush. There are other perks as well. In California, electric vehicles still qualify for special stickers that permit their drivers to travel solo in the state’s carpool lanes. The stickers expire in 2011, but lawmakers are considering extending the privilege until 2016. It’s unclear whether plug-in hybrids will qualify. With all the excitement brewing over electric vehicles, it’s easy to forget that 98~ of the cars sold in America still have traditional drive trains. Simply put, the gasoline engine isn’t going to disappear overnight. Even the most vociferous boosters of plug-in vehicles admit that the greater range and lower cost of internal combustion-powered cars and trucks mean they’ll dominate vehicle sales for at least another decade or two. And for some applications, like hauling a trailer over the Rockies, they may never go away.According to Roland Hwang, we can infer that ______. A．The electric vehicles will take up the automotive market gradually.B．The electric vehicles will quit the automotive market gradually.C．The conventional car is better than the electric vehicles.D．The electric vehicles encounter some challenges.

I came home one day recently and， for reasons I don't quite understand， my living room smelled like my grandmother's house． Suddenly I felt as if I were 12 years old， happy and relaxed， sitting in her kitchen． I can remember what her house looked like， though it was sold 20 years ago --- her three-level plant stand， the plates lining the walls， the window over her sink-but these visual memories don't have the power that smell does． The funny thing is， I can't even begin to describe the odor （气味） that was so distinctively hers． The best I can do is this： "It smelled like my grandmother's house．" It's a common experience， and a common linguistic （语言学的） problem． In cultures worldwide， people have powerful olfactory-memories． This odor-memory link is also called "the Proust phenomenon，" after Marcel Proust's famous description of the feelings aroused by a cake dipped in tea in "Remembrance of Things Past．" Olfactory memories seem to be more closely bound up with emotions than are visual or auditory ones． Not all these memories are pleasant， of course， and smells can also trigger feelings of pain． It is surprisingly hard for English-speakers to describe the odors that occasion such strong emotions， however． English possesses almost no abstract smell words that pick out links or themes among unrelated aromas （芳香）， We have plenty of these in the visual field． "Yellow，" for example， identifies a characteristic that bananas， lemons， some cars， some flowers， old book pages， and the sun all share． But for odors， we don't have many more than the vague "musty" （smells old and stale） and "musky" （smells perfumery）． We usually have no choice but to say that one thing smells like another --- like a banana， like garlic， like diesel fuel． A few languages， though， do have a rich odor vocabulary． Linguist Asifa Majidhas found that the Jahai， the Semaq Beri， and the Maniq， hunter-gatherer groups in Malaysia and Thailand， employ a wide range of abstract smell words and can identify aromas as easily as we can colors． The Jahai have a word， for example， that describes "the seemingly dissimilar smell of petrol， smoke， bat poop， root of wild ginger and wood of wild mango．" Last year my cat got sprayed by a skunk （臭鼬）， and the vet told me to wash its face with coffee to cover the bad smell． Until then， I had never realized that coffee， which I find delicious， smells remarkably like skunk spray， which I do not． Science has identified the chemicals that both share． They are called mercaptans （硫醇）． But in oral English， we have no word for the underlying note that connects these two odors． If the Jahai drank coffee and encountered skunks， I bet they would．（1）The opening paragraph is mainly intended to ____ ．A． express the writer's affection for his grandmotherB． direct the readers' attention to a linguistic problemC． tell us the odor of the grandmother's house stayed the sameD． prove smell has a greater power than visual memories．（2）Which of the following is related to olfactory memories？ ____ A． Forming an image in mind after seeing the word "injury"．B． Feeling sympathetic when seeing a sick cat．C． Dancing to the music upon hearing it played．D． Missing fried eggs with garlic cooked by mum．（3）The example of the Jahai suggests that ____ ．A． the Jahai don't have many words in the visual fieldB． English possesses many vague words like "musty" and "musky"C． the Jahai has more abstract smell words than EnglishD． skunk and coffee have the same smell， but different functions（4）What can we learn from the passage？ ____ A． The author feels pity about the limitation of his language．B． English has a wide range of visual and odor vocabulary．C． Olfactory memories can bring nothing but pleasant feelings．D． Cultures worldwide always collide with each other．

Every day 25 milion U. S. children ride school buses. The safety record for these buses is much better than for passenger cars; but nevertheless, about 10 children are killed each year riding on large school buses, and nearly four times that number are killed outside buses in the loading zones. By and large, however, the nation"s school children are transported to and from school safely. Even though the number of school bus casualties(死亡人数) is not large, the safety of children is always of intense public concern. While everyone wants to see children transported safely, people are divided about what needs to be done—particularly whether seat belts should be mandatory (强制性的). Supporters of seat belts on school buses argue that seat belts are necessary not only to reduce death and injury, but also to teach children lessons about the importance of using them routinely in any moving vehicle. A side benefit, they point out, is that seat belts help keep children in their seats, away from the bus driver. Opponents of seat belt installation suggest that children are already well protected by the school buses that follow the National Highway Traffic Safety Administration"s (NHTSA) safety requirement set in 1977. They also believe that many children won"t wear seat belts anyway, and that they may damage the belts or use them as weapons to hurt other children. A new Research Council report on school bus safety suggests that there are alternate safety devices and procedures that may be more effective and less expensive. For example, the study committee suggested that raising seat backs four inches may have the same safety effectiveness as seat belts. The report sponsored by the Department of Transportation at the request of Congress, reviews seat belts extensively while taking a broader look at safety in and around school buses. Each year, children killed outside buses in the loading zones are about_______.A.10B.40C.30D.50

In recent years，there have been many films about robots trying to take over the world.Studies show that up to 20 million factory jobs worldwide could be taken by robots in the next 10 years.Some people are worried about what might happen in the future. On 8th September，2020，the Guardian printed an article written by a robot called GPT-3.It wrote that "robot" comes from the Greek word for "slave" （奴隶） and humans have nothing to fear from robots，which are only here to help humans.However，the fact that a robot could write such an article has made some people feel even more uneasy.Where is the robot technology heading？Can robots and humans work together peacefully？ YES-they're here to help humans! Robots are created by humans for humans.Robots take on jobs that are too dangerous for people to do by themselves.Although robots might take some people's jobs，they will create new types of work，and they will possibly create more jobs than they take away.Besides，robots are not influenced by feelings，so they are more reliable than humans. NO-humans should not trust robots! Robots are already taking over the world.Jobs that used to be done by human beings are now being taken by robots.Although robots are under our control now，that might not always be the case.An experiment in Switzerland found that some robots had learnt how to lie to each other.With the development of AI （人工智能），robots could start to act in their own interests.Wherever possible，human should do things themselves. What's your opinion on this matter？（1）How do some people feel when learning that GPT-3 wrote an article to argue for robots？ ____ A.Excited.B.Proud.C.Angry.D.Nervous.（2）What is the advantage of robots for humans？ ____ A.Working with rich feelings.B.Acting in their own interests.C.Developing AI technology.D.oing unsafe work for humans.（3）What are some people worried about？ ____ A.Smart robots will take over the world in the next 10 years.B.Humans will create more new jobs than robots take away.C.Robots will be out of the control of humans in the future.D.More films about robots taking over the world will come out.（4）What's the best title for the passage？ ____ A.Will Robots Become More Creative？A.Will Roberts Become More Creative？B.Should Humans Believe in Robots？C.ould Robots Do more for Humans？D.Must Humans Do Things Themselves？
