Google’s self-driving car is designed to work without a gas pedal(踏板)or steering wheel(方向盘). Now, the company has confirmed that the car doesn’t have any windscreen wipers either, because there’s no need for passengers to see where they are being driven.
The car requires no input from a driver, other than telling it the destination. There is no driving in the way we know it and all people inside the cars will be passengers who can spend their time paying no attention to the road. While the car may not need windscreen wipers, the lack of them may make passengers feel helpless if they are unable to see where they are going clearly.
Google’s two-seater “bubble” cars have buttons to begin and end the drive, but no other controls. An on-board computer uses data from sensors, including radar(雷达)and cameras, to make turns and navigate its way around pedestrians and other vehicles. Under the vision made public by Google, passengers might set their destination by typing it into a map or using commands. The new car can’t go faster than 25 miles per hour(40 km/h). It is electric and has to be recharged after 80 miles(129 km). They can only be used in areas that have been thoroughly mapped by Google.
Google has been testing its self-driving cars since 2009 and its steering wheel-less sample since early this summer. It intends on making its driverless cars available to consumers in the next five years. The ultimate goal of the project is computer-controlled cars that can get rid of human error, which results in about 90 percent of the 1.2 million road deaths that occur worldwide each year and it was also inspiring to start with a blank sheet of paper.

Do you ever find yourself spending time on product reviews when you buy something online, only to find that the product you bought is junk(废物)? New research led by Dr. Powell of Stanford University may explain why this happens: it boils down to the number of reviews a product has.
The study found that when choosing between two products online, people tend to favor the one with more reviews despite the fact that the more reviewed product is of lower quality. This is because when shopping online, consumers engage(从事)in a type of “social learning”, where they learn from observing the decisions of other people and the results of those decisions. People attach more importance to the choices of others. When evaluating online products, the item’s rating and number of reviews can be helpful to an unsure customer. But a new study, published in the journal Psychological Science, found that consumers don’t check those figures to learn their true meaning enough. So they fail to do a simple task when viewing online rating and reviews, leading them to purchase products of poor quality. When shopping online, consumers engaging in social learning become informed from the decisions of others. For example, you’re more likely to buy a book at the top of the New York Times’ best-sellers list or buy an app that’s been downloaded millions of times. But looking at other people’s choices is only a part of social learning. However, how people understand or fail to understand this data is affecting their decision-making in a negative way. Overcoming this bias(偏见)is difficult because consumers find comfort in popularity.
Powell and his colleagues also found evidence of this trend beyond the study. “It doesn’t necessarily mean that better things don’t become more popular, but as a consumer, when you’re looking at the number of reviews, it’s not telling you anything,” said Dr. Powell.

Some African schools are adding programs that teach what officials are calling “soft skills” to students. Soft skills are personal qualities that help a person relate effectively to others. Officials say this kind of training can help students succeed in the job market and in life.
The training is being offered at the St. Bernadette Kamonyi Secondary School in Kigali, Rwanda. For weeks, its students have been visiting neighborhood businesses. The goal of these field trips is for the young people to learn what is necessary to secure a job.
For the secondary school students, this information is important. In a few months, they’ll complete their studies and try their best to find work. One of the Rwandan students is 22-year-old Aminadab Niyitegeka. He says he will look for any job available. He hopes that what he learns in his work readiness class will help. Traditionally, secondary schools in Africa have spent more time on subjects like mathematics and science, largely ignoring areas like public speaking and teamwork. But that is changing. Schools are exploring new teaching models to offer soft skills and professional training. It is part of an effort to perpare students to become better communicators, problem solvers and citizens(公民).
Rwanda has started a work readiness training program called Akazi Kanoze Access. It means “work well done” in Kinyarwanda, the official language of Rwanda. The program has trained more than 20,000 students to help make them more appealing to employers.
Emmanuel Ntagungira is a teacher and works as a trainer for Akazi Kanoze Access. He often visits employers who have given jobs to high schools. The employers are very happy because the graduates are ready to work. He says he hopes the program will help lower unemployment, which stands at over 13 percent nationwide. He also explains that the graduates have a healthy mindset and employers are satisfied with the job they’ve been doing.
1.Why do St. Bernadette Kamonyi Secondary School students visit neighborhood businesses?
A. To find some suitable jobs for them.
B. To explore new learning methods.
C. To help the neighbors with daily affairs.
D. To learn some skills to get a job.
2.What do secondary schools in Africa traditionally focus on?
A. Subjects like mathematics and science.
B. Public speaking and teamwork.
C. Communicating skills with employers.
D. New teaching models and skills.
3.What does Emmanuel Ntagungira think of the program?
A. Instructive. B. Beneficial. C. Persuasive. D. Controversial.

"Did you hear what happened to Adam last Friday?" Lindsey whispers to Tori.
With her eyes shining, Tori brags, "You bet I did, Sean told me two days ago."
Who are Lindsey and Tori talking about? It just happened to be yours truly, Adam Freedman, I can tell you that what they are saying is （a） not nice and （b） not even true. Still, Lindsey and Tori aren't very different from most students here at Linton High School, including me. Many of our conversations are gossip （闲话）.I have noticed three effects of gossip: it can hurt people, it can give gossipers a strange kind of satisfaction, and it can cause social pressures in a group.
An important negative effect of gossip is that it can hurt the person being talked about. Usually, gossip spreads information about a topic—breakups, trouble at home, even dropping out—that a person would rather keep secret. The more embarrassing or shameful the secret is, the juicier the gossip it makes. Probably the worst type of gossip is the absolute lie. People often think of gossipers as harmless, but cruel lies can cause pain.
If we know that gossip can be harmful, then why do so many of us do it? The answer lies in another effect of gossip: the satisfaction it gives us. Sharing the latest rumor （传言）can make a person feel important because he or she knows something that others don't. Similarly, hearing the latest rumor can make a person feel like part of the "in group". In other words, gossip is satisfying because it gives people a sense of belonging or even superiority （优越感）.
Gossip also can have a third effect: it strengthens unwritten, unspoken rules about how people should act. Professor David Wilson explains that gossip is important in policing behaviors in a group. Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said, then you can bet that wearing or saying something similar will get you the same kind of negative attention. The do's and don'ts conveyed through gossip will never show up in any student handbook.
The effects of gossip vary depending on the situation. The next time you feel the urge to spread the latest news, think about why you want to gossip and what effects your "juicy story" might have.

It's natural for parents to praise their children, but offering this praise could actually backfire, according to new science.
In the study, researchers at Michigan State University looked at 123 children who were about 7. The team assessed the children to determine whether they had a “growth mindset" (believing that you can work harder to get smarter), or a “fixed mindset" (believing that your intelligence is unable to change). They then asked the children to complete a fast-paced computer accuracy task while their brain activity was recorded.
Based on the data they collected, the researchers concluded that children with a growth mindset were much more likely to have a larger brain response after making a mistake, and in turn were more likely to improve their performance by paying closer attention to the task after making an error.
While previous research has shown that people with a fixed mindset didn't want to admit they had made a mistake, this study found that children with a fixed mindset were able to — “bounce back” after making an error, but only if they gave their full attention to the mistakes. “The main implication here is that we should pay close attention to our mistakes and use them as opportunities to learn study author Hans Schroder told Science Daily.
For parents, the lessons are clear—if a child hands you an A+ test, don't say “You're so smart! ”
Instead, say “Wow, that studying really paid off!" or “You clearly mastered this material — way to go!" Note the effort, not the intelligence.
Second, focus on using errors to work together and learn. Many teachers and parents avoid addressing children's mistakes, telling them “It's OK. You'll get it next time. . . ” Without giving them the opportunity to figure out what went wrong. Dr. Schroder says, "Instead, it's better to
reassure children that mistakes happen, and to pay attention and work to figure out where and how they made the mistakes. ”

D.Lily thinks she can get A+ without any effort.
3.If your child gets the best mark in the test, you should .
A.praise him with some delicious food and money
B.comment him to be cleverer than other students
C.confirm his effort that he has made for the test
D.believe that he is an honest and smart child
4.What should parents do with the child's mistakes from Dr. Schroder?
A.Parents should avoid talking with child about his mistakes.
B.Parents should compare his mistakes with others' and criticize him.
C.Parents should ignore the mistakes and believe he will do better.
D.Parents should analyse the mistakes with their child patiently.
