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 (回复) 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.

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 (荒谬的) 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.

At thirteen, I was diagnosed（诊断）with kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not.

In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, “Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it.”

She glanced down at me through her glasses, “you are no different from your classmates, young man.”

I tried, but I didn’t finish the reading when the bell rang. I had to take it home.

In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn’t get much education. But Louis didn’t give up. Instead, he invented a reading system of raised dots (点), which opened up a whole new world of knowledge to the blind.

Wasn’t I the “blind” in my class, being made to learn like the “sighted” students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up?

I didn’t expect anything when I handed in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day with an “A” on it. At the bottom of the paper were these words: “ See what you can do when you keep trying?”

1.The author didn’t finish the reading in class because .

A．He was new to the class

B．He was tired of literature

C．He had an attention disorder

D．He wanted to take the task home

2.What do we know about Louis Braille from the passage?

A．He made a great invention.

B．He had good sight.

C．He gave up reading.

D．He learned a lot from school.

3.What was Mrs. Smith’s attitude to the author at the end of the story?

A．Angry. B．Impatient.

C．Sympathetic. D．Encouraging.

4.What is the main idea of the passage?

A．The disabled should be treated with respect.

B．A teacher can open up a new world to students.

C．Everyone needs a hand when faced with challenges.

D．One can find his way out of difficulties with efforts.

科目：高中英语 来源：2017届江苏南通中学高三上期中考试英语卷（解析版） 题型：阅读理解

Scientists are debating how to limit their newly-discovered power to change genetic structure (结构). Scientists already modify the genes (基因) of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes, small flying insects, that carry the Zika virus. They might also be able to permanently remove species (物种) of plants and animals that are damaging to other species.

In a report published last week, the U. S. National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released (释放) into the wild.

Sixteen biologists, ethicists (伦理学家) and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms (生物体) from the laboratory into nature.

Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction (繁殖).

Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country's borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet.

【小题１】What possible advantage does gene control in wild animals and plants have?

A. Changing the Zika virus permanently.

B. Getting rid of damaging species forever.

C. Having the changed genes in their next generations.

D. Making all the species more productive and stronger.

【小题２】As for genetically changed wild animals and plants, what are scientists worried about?

A. They may become weaker or die out.

B. They may be more productive than before.

C. They may cause damage to their living habitat.

D. Their genes may spread to later generations.

【小题３】Which of the following is true according to the passage?

A. Scientists are certain what exact results gene modification leads to.

B. Gene modification can benefit some farm animals and agricultural plants.

C. Scientists won't modify any genes before they make the final decision.

D. Gene modification will be encouraged in more creatures in the near future.

【小题４】The article is mainly intended to ________.

A. appeal against research on gene control

B. show how to change genetic structure

C. inform us of power and danger of gene control

D. give the reason why gene modification is necessary
