Do fight against painting pollution
Do you know what kind of things the young people are reading? More and more and teachers have noticed another kind of pollution, which comes from the printed papers on streets.
These printed things newspapers but have hardly anything to do with . You can only find reading materials badly made up there-some are too strange for anyone to ; others are frightening stories of something . However, many of the young readers are getting interested in such reading, which them what they should pay for their breakfast and brings them nightmares and immoral ideas in . Homework is left and daily games lost.
These sellers stand about on streets selling their papers well. The writers, publishers and printers, they are, we never know, are their silent money.
The sheep-skinned wolf’s story seems to have been forgotten once again. Why not this kind of thing? Yes, both teachers and parents have asked each other for more strict control of the young readers. , the more you want to forbid it, the more they want to have a look at it. you may even find several children, driven by their curious natures, one patched paper, which has traveled from hand to hand.
It really does to our society. It has already formed a sort of moral pollution. The teachers and parents need more powerful support in their protection of the young generation. At the same time, the young need more interesting books to help them those ugly paper.

In this competitive world, cause a lot of nervousness in students. For some, exam anxiety encourages them to work hard, while for others it may be the root cause for poor performance, leading to academic and lack of confidence. In fact, some students are anxious by nature and easily get nervous when they face a(n) situation. They will think even if they have prepared well. They fear that they may what they have studied, and when it is too much, their is likely to come true.
One of the most important methods of exam anxiety is to prepare well in advance. Studying regularly for a few hours every day helps increase the of students. If students are not able to handle anxiety or nervousness, they could talk to their teachers, parents, friends or instructors. should also avoid giving pressure to their kids to do well. Creating a peaceful and atmosphere at home can be greatly helpful.

Research has shown that two-thirds of human conversation is taken up not with discussion of the cultural or political problems of the day, not heated debates about films we've just watched or books we've just finished reading, but plain and simple ____.
Language is our greatest treasure as a species, and what do we ____ do with it? We gossip. About others' behaviour and private lives, such as who's doing what with whom, who's in and who's out-and why; how to deal with difficult ____ situations involving children, lovers, and colleagues.
So why are we keen on gossiping? Are we just natural ____, of both time and words? Or do we talk a lot about nothing in particular simply to avoid facing up to the really important issues of life? It's not the case according to Professor Robin Dunbar. In fact, in his latest book, Grooming, Gossip and the Evolution of Language, the psychologist says gossip is one of these really____issues.
Dunbar ____ the traditional view that language was developed by the men at the early stage of social development in order to organize their manly hunting activities more effectively, or even to promote the exchange of poetic stories about their origins and the supernatural. Instead he suggests that language evolved among women. We don't spend two-thirds of our time gossiping just because we can talk, argues Dunbar—____, he goes on to say, language evolved specifically to allow us to gossip.
Dunbar arrived at his cheery theory by studying the ____ of the higher primates（灵长类动物）like monkeys. By means of grooming--cleaning the fur by brushing it, monkeys form groups with other individuals on whom they can rely for support in the event of some kind of conflict within the group or____ from outside it.
As we human beings evolve from a particular branch of the primate family, Dunbar ____ that at one time in our history we did much the same. Grouping together made sense because the bigger the group, the greater the ____ it provided; on the other hand, the bigger the group, the greater the stresses of living close to others. Grooming helped to ____ the pressure and calm everybody down.
But as the groups got bigger and bigger, the amount of time spent in grooming activities also had to be ____ to maintain its effectiveness. Clearly, a more ____ kind of grooming was needed, and thus language evolved as a kind of vocal（有声的）grooming which allowed humans to develop relationship with ever-larger groups by exchanging information over a wider network of individuals than would be possible by one-to-one ____ contact.

And the landing craft set down on the surface. in the Viking One Lander immediately sent a message to the earth. It said, “I am here. I am down safely. I am beginning my work. ”
The message at the speed of light. It took twenty minutes to reach the earth, more than three hundred and twenty million kilometers . Scientists and engineers at the control center .
Moments later, television receiver in the control center began to the first picture from Viking One. People at the center could see the feet of the landing craft sitting firmly on the 11 soil of Mars. Those pictures were our first look at the planet. They showed a red surface, full of rocks, with no sign of . It was our first look at a planet that is full of surprises, mysteries and promise. Viking One was launched toward Mars in August, 1975. The spaceship had two : an orbiter(轨道飞行器)and a lander(着陆器). The orbiter would circle Mars. It would take pictures of Mars’ surface. It would the atmosphere.
The would go down to the surface. It would carry to dig up and study soil and .
It also would report about any evidence of life on the planet. The lander would send this to the orbiter and then back to the earth.

The mental aspect of athletics is underrated. The common expression, “athletics are 90 percent ____ and 10 percent physical,” is often used by coaches, and stresses that mindsets make a huge ____ in competitions.
“The physical aspect of the sport can only take you ____ ,” said Olympic gold medal-winning gymnast Shannon Miller during an interview with the Dana Foundation. “The mental aspect has to ____ , especially when you’re talking about the best of the best. In the Olympic games, everyone is talented. Everyone ____ hard. Everyone does the work. What ____ the gold medalists from the silver medalists is simply the mental game.”
Many athletes have used the technique of mental imagery, or ____ , to perform at their best. Research on the brain patterns of ____ found that the patterns activated when a weightlifter lifted heavy weights were activated ____ when they simply imagined lifting and some studies have suggested that mental ____ can be almost as effective as physical training.

It’s the place where smart people make smart machines work even smarter. It’s also in the heart of sunny California, a great place to start a family and raise kids. What could be better?
But something is happening to their children. Up until the age of two they develop normally. But then everything seems to go backwards. The children become locked into their own small world, unable to communicate at all.
They call it the “curse(诅咒)of Silicon Valley,” but the medical name for the condition is autism(自闭症). It used to be thought that autism was a kind of mental illness. Now doctors are sure that it is a neurological disease transmitted genetically. It seems that the people leading the communications revolution are having children who cannot communicate at all.
But even the parents have trouble communicating. Asperger’s Syndrome is a mild version of autism. People who have it are highly intelligent and often brilliant with numbers or system but have no social skill. This very combination of symptoms makes Asperger’s sufferers into ideal computer professionals.
The Asperger’s sufferer has always been a well—known figure in popular culture. He or she was the eccentric but dedicated scholar or the strange uncle or auntie who never married. But the high numbers of such people in Silicon Valley mean that they can meet others who understand them and share their interests. And while they might not be personally attractive, they can earn truly attractive amounts of money. They can get married and have kids. Unfortunately, many of the children of two Asperger’s parents seem to be developing serious autism.
There is little anyone can do. It takes hours of work just to make autistic child realize that anyone else exists. And there is no cure in sight. Some argue that no cure should be found. “It may be that autistics are essentially different from normal people, but that these differences make them invaluable for the evolution of the human race,” says Dr. Kirk Whilhelmsen of the University of California. “To eliminate the genes for autism could be disastrous. ”
It seems that the children of Silicon Valley are paying the price of genius.What does Dr Kirk Whilhelmsen think of autism?
| A．It is disastrous to society. |
| B．It is not completely a bad thing. |
| C．It is a punishment to those working in Silicon Valley. |
| D．People with autism should never marry. |
What can we learn about autism according to the passage?
| A．It is believed to be a king of mental illness that can be cured. |
| B．People with autism can’t find people sharing their interests. |
| C．They do not care about the presence of others. |
| D．They are a burden for the society. |
Why do people call autism “curse of Silicon Valley”？
| A．Because autistic people live in Silicon Valley. |
| B．Because many people working in Silicon Valley have autism children. |
| C．Because people with autism will be driven out of Silicon Valley. |
| D．Because people with autism are not personally attractive and not liked by others. |
What can we know about Asperger’s Syndrome according to the passage?
| A．Asperger’s sufferers are ideal computer professionals. |
| B．Asperger’s sufferers never get married and have children. |
| C．Asperger’s sufferers are ashamed of themselves and locked into their own world. |
| D．Asperger’s sufferers can be beneficial to society if they are cured. |

As he graduates to the later stages of childhood bordering on the teenage years, the child learns the of human relations and socialization by interacting with his peers—his friends and schoolmates． He also learns to with new life situations, including dates and part-time work． Given a tight schedule of schoolwork, the child learns to prepare his own schedules of work and play; the more________ and less serious ones manage to take time out of their busy schedules of assignments, reports and tests and examinations to go with their friends on relaxation entertainment．

Beware of those who use the truth to deceive(欺骗). When someone tells you something that is , but leaves out important information that should be , he can create a false impression.
For example, someone might say, “I just a hundred dollars on the lottery. It was great. I took that dollar ticket back to the store and it in for one hundred dollars!”
This guy is a winner, ? Maybe, maybe not. We then discover that he bought two hundred , and only one was a winner. He’s really a big !
He didn’t say anything that was , but he deliberately left out some important . That’s called a half-truth. Half-truths are not technically , but they are just as not .
Untrustworthy candidates in campaigns often use this tactic(手段). Let’s say that during Governor Smith’s last term, the state lost one million jobs and three million jobs. Then she another term. One of her opponents runs an ad , “During Governor Smith’s term, the state lost one million jobs!”That’s true. , an honest statement would have been, “During Governor Smith’s term, the state had a net gain of million jobs. ”
Advertisers will sometimes use half-truths. It’s the law to make false claims so they try to mislead you with the . An ad might boast, “Nine out of ten doctors recommend Yucky Pills to cure nose pimples. ”It to mention that they only asked ten doctors and nine of them work for the Yucky Corporation.
This kind of deception happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
