The average(平均的)American child spends three to five hours a day watching TV. In 1961, the average child began to watch television at age three; however, today it is nine months. Yet, most parents think that television has bad influence on their children. For example, in the early 1970s, my parents believed that my bad eyesight was the result of sitting too close to the screen, and they therefore made my stay at least six feet from it. Today, most people have no such worry, but many new ridiculous (荒謬的) sayings have appeared:

*TV makes kids stupid. Many children watch more educational programs when they are pre-schoolers. When they grow up, they can read more books and have much better ideas to solve difficult problems than other children.

*TV makes kids violent. The real story is not so simple. Hundreds of studies show that watching violence on TV makes children more aggressive (好斗的). But a study of over 5,000 children also finds that some positive programs make children kinder. The problem is that kids are increasingly watching shows with violence instead of those suitable for their age.

*Sitting around watching TV makes kids overweight. An experiment finds that when children watch less television, they do lose extra weight; however, reducing their television time does not make them more active. The real problem lies in snacking (吃零食). A widespread habit for kids, and junk-food advertisements.

*TV helps kids get to sleep. The opposite is true. The more television children watch, the more likely they are to have irregular sleep and nap (小睡) patterns. Allowing kids to watch television is part of the problem, not the solution.

1.Which one is the advantage of educational TV programs?

A. They will make children solve difficult problems better than others.

B. they will improve children’s ability to get along with others.

C. They are likely to make children more aggressive.

D. They will make sure of children’s success in the future.

2.Why are children spending much time watching TV likely to be fat?

A. Watching TV makes children lazy and inactive.

B. Children are attracted by the food advertisement on TV.

C. Watching TV doesn’t burn up as much fat as doing sports.

D. Children like to snack while watching TV.

3.What influence does watching TV have on a child’s sleep?

A. Children are likely to sleep deeper after watching TV.

B. Children’s sleep time will be greatly reduced.

C. It will make children form a bad habit of sleeping.

D. It will make children sleep easier.

4.What is the purpose of this text?

A. To increase people’s knowledge of watching TV.

B. To warn parents of the disadvantages of watching TV.

C. To explain the bad influences that watching TV has on children.

D. To correct parents’ wrong ideas of television’s effect on children.

“Nature does not hurry, yet everything is accomplished.”---Lao Tzu

If you are in a city where everyone rushes, realize that you don’t have to be like everyone else. You can be different. You can walk instead of driving in rush hour traffic. You can be on your iPhone or Blackberry less, and disconnected sometimes. Your environment doesn’t control your life---you do. I’m not going to tell you how to give you a step-by-step guide to moving slower. 1.

1. Do less.

Cut back on your projects, on your task list, on how much you try to do each day. 2. Pick 2-3 important things--- or even just one important thing--- and work on those first. Save smaller, routine tasks for later in the day, but give yourself time to focus.

2. 3.

Meeting are usually a “big waste of time”. And they eat into your day, forcing you to squeeze the things you really need to do into small windows, and making you rush.

3. Start to put off or cancel the unnecessary.

When you do the important things with focus, without rush, there will be things that get pushed back, and that don’t get done. And you need to ask yourself: 4. What would happen if I stopped doing them?

4. Practice mindfulness.

5. , rather than things so much about future or the past. When you eat, fully appreciate your food. When you are with someone, be with them fully. When you are walking, appreciate your surroundings, no matter where you are.

Try these things out. Life is better when unrushed. Remember the quote: if nature can get everything done without rushing , so can you.

A. Have fewer meetings

B. How necessary are these things?

C. Simply learn to live in the present

D. Focus not on quantity but on quality

E. Give yourself more time to get ready and get there.

F. The world likely won’t end if you don’t pass one of the examinations.

G. But here are some things to consider and perhaps adopt, if they work for your life.

根據(jù)短文內(nèi)容,從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

1. When a starving man gets a meal, he begins to think about an overcoat; when an executive gets a new sports car, visions of country clubs and pleasure beats dance into view.

The many wants of mankind might be regarded as making up several levels. 2..

The first and most basic level of wants involves food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. 3. It included such items as automobile sand new houses.

By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the “l(fā)ife-enriching”level. While the other levels involve physical satisfaction-the feeding, comfort, safety, and transportation of the human body-this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called “l(fā)uxury” items. Among them are vacation trips, the best medical care, and entertainment. 4.

On this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?

A fifth level probably would involve wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. 5.In this way, we can enjoy more fully the good things on the first four levels.

A.Then a third level appeared.

B.Human wants seem endless.

C.When there is money enough to satisfy one level of wants, another level appears.

D.There are several levels of wants in one’s life.

E.At this stage, we now may seek to ensure the health, safety, and leisure.

F.Also included here are fancy foods and the latest styles in clothing.

G.Different people have different wants on each level.

Everyone gathered around and Paddy read out loud, slowly, his tone growing sadder and sadder. The little headline said: BOXER RECEIVES LIFF SENTENCE.

Frank Cleary, aged 26, professional boxer, was today found guilty of the murder of Albert Gumming, aged 32, laborer, last July. The jury(陪審團(tuán)) reached its decision after only ten minutes, recommending the most severe punishment to the court. It was, said the Judge, a simple case. Cumming and Cleary had quarreled violently at the Harbour Hotel on July 23rd and police saw Cleary kicking at the head of the unconscious Gumming. When arrested, Cleary was drunk but clear-thinking.

Cleary was sentenced to life imprisonment with hard labour. Asked if he had anything to say, Cleary answered, “Just don’t tell my mother.”

“It happened over three years ago,” Paddy said helplessly. No one answered him or moved, for no one knew what to do. “Just don’t tell my mother,” said Fee numbly(麻木地). “And no one did! Oh, God! My poor, poor Frank!”

Paddy wiped the tears from his face and said. “Fee, pack your things. We’ll go to see him.”

She half-rose before sinking back, her eyes in her small white face stared as if dead. “I can't go,” she said without a hint of pain, yet making everyone feel that the pain was there. “It would kill him to see me. I know him so well—his pride, his ambition. Let him bear the shame alone, it’s what he wants. We’ve got to help him keep his secret. What good will it do him to see us?”

Paddy was still weeping, not for Frank, but for the life which had gone from Fee’s face, for the dying in her eyes. Frank had always brought bitterness and misfortune, always stood between Fee and himself. He was the cause of her withdrawal from his heart and the hearts of his children. Every time it looked as if there might be happiness for Fee, Frank took it away. But Paddy’s love for her was as deep and impossible to wipe out as hers was for Frank.

So he said, “Well, Fee, we won’t go. But we must make sure he is taken care of. How about if I write to Father Jones and ask him to look out for Frank?”

There was no excitement in the eyes, but a faint pink stole into her cheeks. “Yes, Paddy, do that. Only make sure he knows not to tell Frank we found out. Perhaps it would ease Frank to think for certain that we don’t know.”

1.Paddy cried because he thought ________.

A. what had happened to Frank was killing Fee

B. Frank should have told Fee what had happened

C. Frank did kill someone and deserved the punishment

D. Frank had always been a man of bad moral character

2.The underlined sentence “She half-rose before sinking back...” in Paragraph 6 shows that ________.

A. Fee was so heart-broken that she could hardly stand up

B. Fee didn’t want to upset Paddy by visiting Frank

C. Fee struggled between wanting to see Frank and respecting his wish

D. Fee couldn’t leave her family to go to see Frank

3.What can be inferred from the passage?

A. The jury and the judge agreed on the Boxer’s Sentence of Life Imprisonment.

B. Frank didn’t want his family to know the sentence to him, most probably out of his pride.

C. The family didn’t find out what had happened to Frank until 3 years later.

D. The police found Gumming unconscious, heavily struck by Frank.

4.What is Frank and Paddy’s probable relationship with Fee?

A. Frank is Fee’s son and Paddy is Fee’s brother.

B. Frank is Fee’s lover and Paddy is Fee’s husband.

C. Frank is Fee’s brother and Paddy is Fee’s lover.

D. Frank is Fee’s son and Paddy is Fee’s husband.

If you like texting and are trying to lose weight, a new study found that using texting to track diet and exercise habits may help you lose weight.

Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are trying to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.

Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.

The study included 26 obese women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (回復(fù)) and tips.

Every morning, the women received a text from an automated system that said, “Please text yesterday’s personal information of steps you walked and how many sugary drinks you had.” Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.

After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.

“Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior,” Dori Steinberg, who was responsible for this research, said.

Steinberg said, "Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cellphone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time.”

1.According to the study, traditional methods _________.

A. are easier for people to lose weight

B. may cause people to give up losing weight

C. provide brief feedback and tips

D. are easy to track diet and exercise behavior

2.Which is NOT true about text messaging according to Steinberg?

A. It saves time.

B. It saves money.

C. It can be entered quickly.

D. It is easy to receive feedback.

3.What’s the best title for the text?

A. Texting helps keep healthy

B. Texting saves time and money

C. Texting can help you lose weight

D. Texting provides brief feedback and tips

4.What’s Dori Steinberg’s attitude towards text messaging?

A. Unknown. B. Negative.

C. Positive. D. Unconcerned.
