One out of every six Americans work at putting together the parts of cars, driving trucks, building roads or filling cars with gas. Most Americans find it hard to think what life would be without a car. However, some have realized the serious problem of air pollution by cars. The polluted air is poisonous and dangerous to health. One way to get rid of the polluted air is to design a new car that does not pollute. That's what several large car factories are trying to do. But to build the new car is easier said than done. Progress in this field has been slow. Another way is to take place of the car engine by something else. Engineers are now working on some new cars. Many makers believe that it will take years to develop a practical model that pleases man. To prevent the world from being polluted by cars, we'll have to make some changes in the way many of us live. Americans, for example, have to cut down the number of their cars they are encouraged to travel and go to work by bike. Riding a bike is thought to help keep the air clean. But this change does not come easily, a large number of workers may find themselves with no jobs if a car factory closes down. And the problem of air pollution would become less important than that of unemployment. Question: Large car factories are trying to build a clean car, _ Options: A: which is clean itself B: which does not pollute the air C: which is used to clean streets D: which is easier to make

Article: Dining in a completely dark room, unaware what's on your plate while sitting next to a complete stranger may not sound like an ideal restaurant experience but it's certainly an _ way to spend a rainy night in London. Dans le Noir, close to London's financial district, is a restaurant full of blind waiters and waitresses who become your eyes around the restaurant, whose original Paris branch opened in 2004. In the bar with the light, you choose whether you want the fish, meat or vegetable, but the dishes themselves remain a secret, as do the ingredients of the "surprise" cocktails. Bags, coats and devices that light up, including watches and mobile phones, are kept in the bar. Placing your hand on the shoulder of your guide, you are led to a table in a black dining room that sets up to 60 people. And it is dark. The waiters tell you when the food is being placed down in front of you, then the fun begins, trying to get food into your mouth, then identifying just what it is that's on your plate, and finally whether you have missed any of it. It's also a great chance to break social convention and eat using your fingers. Those same fingers are also the only way you can tell how much wine you're pouring into your glass. The happy atmosphere in the dining room also made the night memorable. You can't really avoid talking to the person next to you at the long tables and guessing what the dishes are certainly provides adequate fuel for the conversations. All will be revealed at the end of the meal when you are led back out into the lit bar. Not only do you finally get to see what you've just been eating but also who you' ve been talking to for the last 90 minutes. Question: We know from the text that the customers in "Dans le Noir" _ . Options: A: are forbidden to eat with their fingers B: can talk to the strangers at table C: will book the menu in a dark bar D: can take their mobile phones into the dining room

Article: Sometimes,you just can't help it.Maybe you're watching a sad movie,or thinking about the friend who moved away.Next thing you know,your eyes are watering,and you have tears running down your cheeks.Why do people cry when they are emotional? What are tears? Scientists are working hard to find the answers to these questions. Ad Vingerhoets is a professor of psychology at Tilburg University,in the Netherlands.He is one of the few scientists in the world who have studied crying.According to Vingerhoets,there are three types of tears.Basal tears are the first type.They lubricate the eyes and act as a protective barrier between the eye and the rest of the World.Next are reflex tears.They wash your eyes clean when something gets in them.Finally,there are emotional tears. "These are released in response to emotional states,"explains Vingerhoets."Especially when we feel helpless." Scientists believe that crying has something to do with how humans developed and learned to depend on each other."Humans are very complex social creatures,"says Lauren Bylsma,a professor at the University of Pittsburgh,in Pennsylvania."It seems that tears serve to arouse help and support from others,''She says."Another reason we weep is that humans have the longest developmental period of almost any animal.It takes a long time to grow up." Vingerhoets agrees."I think that the reason why humans shed tears has something to do with our childhood,"he says."That's the time when we are stir dependent on adults for love and protection and care.The major advantage of emotional tears is that you can target them at a specific person."Vingerhoets says this ability to target someone could have come in hand in prehistoric times,when humans were living among dangerous animals.Crying could attract predators .Tears were a safer way to get attention.In this case,it is better to use a silent signal to ask for help,"he says. Vingerhoets and Bylsma do frequent studies to better understand why humans cry.According to Byhma,there is still much more to... Question: What's the function of tears according to Bylsma? Options: A: It helps human develop longer. B: It helps humans attract predators. C: It helps arouse attention. D: It helps people to be independent.
