How Teens Can Stay Fit

Any type of regular, physical activity can improve your fitness and your health. Doing physical exercise is easy, but the difficult thing is that you keep moving!1., like brushing your teeth, eating, and sleeping. It can be in gym class, joining a sports team, or working out on your own. Keep the following tips in mind:

2.. A good mental attitude is important. Find an activity that you think is fun. You are more likely to keep with it if you choose something you like. A lot of people find it’s more fun to exercise with someone else, so see if you can find a friend or family member to be active with you.

Take it one step at a time.3.. For example, walk or ride your bike to school or to a friend’s house instead of getting a ride. Get on or off the bus several blocks away and walk the rest of the way. Use the stairs instead of taking the elevator or escalator.

Get your heart pumping(跳動). Whatever you choose, make sure it includes aerobic(有氧的) activity that makes you breathe harder and increases your heart rate. This is the best type of exercise because it increases your fitness level and makes your heart and lungs work better.4.. Examples of aerobic activities are basketball, running, or swimming.

Don’t forget to warm up with some easy exercises or stretching(拉伸) before you do any physical activity.5.. Stretching makes your muscles and joints more flexible too. It is also important to stretch out after you exercise to cool down your muscles.

A. It also burns off body fat

B. Stay positive and have fun

C. Physical exercise can help prevent diseases

D. Small changes can add up to better fitness

E. Exercise should be a regular part of your day

F. This warms your muscles up and may help protect against injury

G. Do the activity as often as possible, but don’t exercise to the point of pain.

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（同齡人）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.

1.Why did Tom give up studying?

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.

2.What seems to have a bad effect on students like Tom?

A. Peer groups.

B. A special unit.

C. The student judges.

D. The home environment.

3.What should schools do to help the problem schoolboys?

A. Wait for their change patiently.

B. Train leaders of their peer groups.

C. Stop the development of street culture.

D. Give them lessons in a separate area.

4.A teacher's work is most effective with a schoolboy when he .

A. is with the boy alone

B. teaches the boy a lesson

C. sends the boy home as punishment

D. works together with another teacher

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.

1.When he first met the author, David ________.

A. felt a little excited B. walked energetically

C. looked a little nervous D. showed up with his teacher

2.As a psychologist, the author ________.

A. was ready to listen to David

B. was skeptical about psychology

C. was able to describe David's problem

D. was sure of handling David's problem

3.What can be interred about David?

A. He recovered after months of treatment.

B. He liked biking before he lost his family.

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

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

科目：高中英語 來源：河南省畢業(yè)年級考前預(yù)測英語試卷 題型：閱讀理解

Is it possible to persuade mankind to live without war? War is an ancient institution which has existed for at least six thousand years. It was always bad and usually foolish, but in the past the human race managed to live with it. Modern creativity has changed this. Either man will abolish war, or war will abolish man. For the present, it is nuclear weapons that cause the most serious danger, but bacteriological (使用細(xì)菌的) or chemical weapons, may soon offer an even greater threat. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do this, we need to persuade mankind to look upon international problems in a new way, not by contests of force, in which the victory goes to the side which is the most skillful in killing people, but by arbitration (仲裁) according to agreed principles of law. It is not easy to change very old mental habits, but this is what must be attempted.

There are those who say that the adoption of this or that thought would prevent war. I believe this to be a big error. All thoughts are based on statements which are, at best, doubtful, and at worst, totally false. Their followers believe in them that they are willing to go to war in support them.

The movement of world opinion during the past few years has changed very largely such as we can welcome. It is believed that nuclear war must be avoided. Of course very difficult problems remain in the world, but the attitude towards them is a better one than it was several years ago. It has begun to be thought, even by the powerful men who decide whether we shall live or die, that people should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important conflict nowadays is not between different countries, but between man and the atom bomb.

1.It is implied in the first paragraph that war now is ________.

A. as bad as in the past B. as necessary as in the past

C. worse than in the past D. not so dangerous as in the past

2.The underlined word "this" in Paragraph l probably refers to "________".

A. improving weapons B. abolishing war

C. solving international problems D. living a peaceful life

3.From Paragraph 2, we learn that the author ________.

A. is a supporter of some modem thoughts

B. has no doubt about the truth of any thought

C. believes the adoption of some thoughts could prevent war

D. does not think the adoption of any thought could stop war

4.What can be inferred about war according to the author?

A. It must be abolished if man wants to survive.

B. It is the only way to solve international problems.

C. It is impossible for the people to live without war.

D. It will be less dangerous because of the improvement of weapons.

科目：高中英語 來源：寧夏石嘴山市2016-2017學(xué)年高二下學(xué)期期末（2018屆高三入學(xué)）考試英語試卷 題型：閱讀理解

Should we allow modern buildings to be built next to older buildings in a historic area of a city? In order to answer this question, we must first examine whether people really want to preserve the historic feel of an area. Not all historical buildings are attractive. However, there may be other reasons—for example, economic (經(jīng)濟(jì)的) reasons—why they should be preserved. So, let us assume that historical buildings are both attractive and important to the majority of people. What should we do then if a new building is needed?

In my view, new architectural styles can exist perfectly well alongside an older style. Indeed, there are many examples in my own home town of Tours where modern designs have been placed very successfully next to old buildings. As long as the building in question is pleasing and does not dominate (影響) its surroundings too much, it often improves the attractiveness of the area.

It is true that there are examples of new buildings which have spoilt (破壞) the area they are in, but the same can be said of some old buildings too. Yet people still speak against new buildings in historic areas. I think this is simply because people are naturally conservative(保守的)and do not like change.

Although we have to respect people’s feelings as fellow users of the buildings, I believe that it is the duty of the architect and planner to move things forward . If we always reproduced what was there before, we would all still be living in caves. Thus, I would argue against copying previous architectural styles and choose something fresh and different , even though that might be the more risky choice.

1.What does the author say about historical buildings in the first paragraph?

A. Some of them are not attractive.

B. Most of them ate too expensive to preserve.

C. They are more pleasing than modern buildings.

D. They have nothing to do with the historic feel of an area.

2.Which of the following is true according to the author ?

A. We should reproduce the same old buildings.

B. Buildings should not dominate their surroundings.

C. Some old buildings have spoilt the area they are in.

D. No one understands why people speak against new buildings.

3.By “move things forward ” in the last paragraph , the author probably means“ ”

A. destroy old buildings

B. put things in a different place

C. respect people’s feelings for historical buildings

D. choose new architectural styles

4.What is the main purpose of the passage?

A. To explain why people dislike change.

B. To argue that modern buildings can be built in historic areas.

C. To warn that we could end up living in caves.

D. To admit how new buildings have ruined their surroundings.
