Tom was one of the brightest boys in the year,with supportive parents.But when he was 15 he suddenly stopped trying.He left school at 16 with only two scores for secondary school subjects.One of the reasons that made it cool for him not to care was the power of his peer(同龄人)group.

The lack of right male role models in many of their lives—at home and particularly in the school environment—means that their peers are the only people they have to judge themselves against.

They don't see men succeeding in society so it doesn't occur to them that they could make something of themselves.Without male teachers as a role model,the effect of peer actions and street culture is all-powerful.Boys want to be part of a club.However,schools can provide the environment for change,and provide the right role models for them.Teachers need to be trained to stop that but not in front of a child's peers.You have to do it one to one, because that is when you see the real child.

It's pointless sending a child home if he or she has done wrong.They see it as a welcome day off to watch television or play computer games.Instead,schools should have a special unit where a child who has done wrong goes for the day and gets advice about his problems—somewhere he can work away from his peers and go home after the other children.

A. He disliked his teachers.

B. His parents no longer supported him.

C. It's cool for boys of his age not to care about studies.

D. There were too many subjects in his secondary school.

Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled-to $1.01 per pack-smokers have jammed telephone "quit lines" across the country seeking to kick the habit.

This is not a surprise to public health advocates. They've studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase.

The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely.

In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost $10.06 at one drugstore Wednesday. In Charleston, S.C., where the 7-cent-a-pack tax is the lowest in the nation, the price was $4.78.

The influence is obvious.

In New York, high school smoking hit a new low in the latest surveys-13.8%, far below the national average. By comparison, 26% of high school students smoke in Kentucky. Other low-tax states have similarly depressing teen-smoking records.

Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans "who choose to smoke".

That's true. But there is more reason in keeping future generations of low-income workers from getting hooked in the first place. As for today's adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better.

One day, when I was working as psychologist in England, an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me. “This boy has lost his family,” he wrote. “He is understandably very sad and refuses to talk to others, and I’m very worried about him. Can you help?”

I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn't have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically.

The first two times we met, David didn't say a word. He sat there, only looking up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon-in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.

Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company. But why did he never look at me?

“Perhaps he simply needs someone to share his pain with,” I thought. “Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.

“It's your turn,” he said.

After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times, about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.

Maybe I gave David something. But I also learned that one-without any word-can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.

C. He went into university soon after starting to talk.

D. He got friends in school before he met the author.

Artificial intelligence keeps defeating human, it is making countless victories against human in different fields of life and trying to push human to the corner.

Google’s DeepMind has defeated the world’s number one player Ke Jie. Human brain somehow has been replaced by a machine and scientists are working very hard on developing a human brain by implanting a chip and connecting it to the thick neuron that connects the two hemispheres of the brain. Well, who doesn’t want to get his brain upgraded to be as smart as the brain of Albert Einstein or Charles Darwin?

Humans will probably one day invent a brain that can be implanted in the human skull and reprogram all the human thoughts, but this invention doesn’t seems to be happening in the foreseeable future since human brain took millions of years to evolve. Some scientists believe that human will defeat death in the next twenty hundred years but they can’t really predict how long it’s going to take to develop a human brain that can completely replace the natural brain.

Despite of this accomplishment in the field of artificial intelligence, it couldn’t crease people from believing that science can’t stand alone. For instance, AI can imitate human brain and most of the time outperforms it, but there are still a lot of hidden secrets. AI outsmarted Ke Jie has consciousness unlike the AI, Ke Jie felt sad when he was defeated and buried his face in his hands but the AI didn’t feel happy and celebrate his victory.

The computer of 1960 is the same as the computer of 2017 in terms of consciousness, there is no signs so far telling us that there is an algorithm(运算)that can make a conscious computer and decipher (译解) its feelings. We can predict what the future will look like according to the past, especially from scientific point of view but the development of human brain seems unpredictable and unknown.
