Young American adults own smartphones at a higher rate than any other age group.

Researchers from Duke University wanted to see if using the smartphone with a low-cost weight-loss App might help young adults in the US who are overweight. If you're rooting for smartphones to solve all our health problems,you're not going to like what the researchers found.The smartphone App doesn't help young adults lose any weight

The study looked at 365 young adults aged 18 to 35.A third of the young adults used an Android App created for the study,which not only tracked their calories,weight and exercise but also offered interactive features like goal setting.games and social support.Another third of the young adults received six weekly personal coaching courses,followed by monthly phone follow-ups.Plus,this personal coaching group was also encouraged to track thcir weight, calories and exercise by smartphones.The last third of young adults were put into a control group and given three necessities on healthy eating and exercise-nothing else.

Researchers tracked the young adults progress after six months,one year and two years. The personal coaching group lost more weight than the other two groups at the six-month mark, but that lead(领先)disappeared at the one-and two-year follow-up.As for the group using the smartphone App,their average weight loss was never more than the other two groups. Lead author Laura Svetkey says that she and her colleagues were both surprised and disappointed at the results.“Given the power of cell phone apps and the popularity of these health and fitness apps,we thought this might be good to provide an effective solution at a low cost,”says Svetkey.

But Svetkey says it's difficult to get the same level of intensity(强度)in an App that you might get through personal coaching,Plus,she says,people tend to stop using weight-loss apps after a while.

There are good reasons to help young adults control their weight.Weight gain during the young adult years is associated with a variety of health problems later in life,including metabolic syndrome and cardiovascular disease.

Since I am a young American adult who uses a popular weight-loss App on my iPhone,I wonder if there is any real harm in using one of these apps,even if they aren't proven effective in research studies.So I turn to Svetkey.She says,"These study results aren't the reason to give up hope about the potential for weight-loss apps,but instead are the reason to strengthen research efforts.More work is needed to understand how to use the technology and show its strengths in a way that will lead people to change their eating and exercise behaviors.”

1.The underlined part"rooting for”in Paragraph 2 is closest in meaning to“".

A.the group using the smartphone App lost the most weight

B.participants in the control group failed to lose weight

C.all participants surveyed gains weight two years later

D.the personal coaching group was more successful at the six-month mark

All languages change over time, but some change at a faster rate than others. 1. The most important factors are the number of people who speak a language, where they live and whether they move around, the importance of the language for world trade and communication, and changes in technology.

2. However, today English is the most widely used language in the world. English is spoken by about 350 million people as a first language in countries such as Great Britain, the United States. In addition, about a billion more people speak English as a second language.

English started to take over French as an international language during the period of British colonialism (殖民主义) when the English ruled many countries in Africa and Asia. 3. The colonial period came to an end at the same time that several other changes occurred. For example, the U.S. started to play a greater part in global affairs and the international economy. New means of communication technology such as television and the Internet spread English worldwide. 4. In addition, they could use the Internet for information, business, or e-mail communication, all in English. Just as the use of English spread, other languages changed English by contact or by new inventions and technology.

In contrast, Icelandic is a language that has changed very slowly. Icelandic speakers today can understand poetry written in a slightly different dialect over 1,000 years ago! Why has Icelandic changed so slowly? The main reason is the isolated (孤立的) location of the island in the middle of the Atlantic Ocean. 5. Compared to England, Iceland had no history of colonialism. Iceland’s small population has not played a major role in international trade or communication. Today, most Icelanders speak English in addition to their native language. With outside influences, Icelandic is changing more rapidly now.

A. People everywhere could watch the news or sports events in English.

B. These changes have a great influence on the development of society.

C. Isolation meant that for hundreds of years, Icelanders had little contact with speakers of other languages.

D. What are some of the factors that influence how quickly a language changes?

E. The language communication brings about the communication of technology.

F. In the past, other languages such as Latin or French were more important than English.

G. English was the primary means of communication in these colonies.

As a young adult, Noah Webster was a teacher. At this time, the colonies were fighting for independence from Britain. Yet the books that American children used in school all came from Britain. The books were all about British people and British places. Webster wanted books that would mean more to American children. So he wrote three books that used American examples — a grammar book, a spelling book, and a reader. These books were very popular, and millions of them were sold.

Webster was interested in changing the spellings of words. He wanted words to be spelled the way they were pronounced. For example, he thought the word “head” should be spelled “hed”, and the word “laugh” should be spelled “laf”. People liked Webster’s suggestions.

However, few words were actually changed. One group of words that were changed were words in which an unpronounced “u” followed an “o”. That is why Americans write “color” and “labor”, and the British write “colour” and “labour”.

With the money he made from his books, Webster was able to write. It was the first American English dictionary, published in 1828. Webster’s dictionary had over 70000 words and gave the meaning and origin of each. To this day, Webster’s work is the example that most dictionaries of American English follow.

1.Which of the following statements is right?

A. Noah Webster had to borrow books from Britain when he was a student.

B. Noah Webster had his own government when he was very young.

C. When Noah Webster taught at schools, he wrote some story books.

D. As a teacher, Noah Webster wasn’t satisfied with the books he used.

2.The third paragraph mainly tells us that ________.

A. Webster spoke English in a different way

B. American people didn’t write English as exactly as English people did

C. Webster was good at correcting mistakes in textbooks

D. American people didn’t like speaking English

3.In American history, Noah Webster is famous for ________.

A. his teaching methods

B. his dictionary

C. his fighting for freedom

D. learning foreign languages

4.The last sentence of this passage means ________.

A. most dictionaries in the world are the copies of Webster’s

B. most dictionaries in American English have the characteristics of Webster’s

C. most American people followed Webster’s advice on writing

D. Webster’s dictionary is the only one used in the United States

Many Chinese students think American students enjoy more freedom than them at school. But American schools also have their rules. If the students break the rules, they will get punishment, too

On the first day of a new term, 128 students of Morton High School were sent home for wearing the wrong clothes. There are altogether 1, 200 students in the school. Usually only 20 students break the school dress rule every day. So the headmaster Theresa Mayerik said it was the worst new term she had ever seen.

At Morton High School, students' favorite clothing such as baggy( 宽大的) trousers, low-necked shirts and tanktops(坎肩) are not allowed in classrooms. Some students think they have the right to choose what to wear. But the headmaster doesn’t think so. "I'd be supportive if half the school were sent home, because 99% will get the message that our school is for education.” “ Freedom” does not mean“ free of restrictions(约束)”. That is to say there is no total freedom in the world, no matter in the US or in China.

1.Many Chinese students think that　　　　　　　　　　　　 .

A.American students are very free at school

B.American students are not so clever as them

C.American students don't love their school at all

D.there is no freedom in American schools

2.128 students of Morton High School were sent home for　　　　　　　　　　　　 .

A.not finishing their homework B.being late for school

C.not wearing the right clothes D.not listening to the teachers in class

3.What does the underlined word"supportive "mean in Chinese?

A.高兴的 B.支持的

American middle school students don’t seem to care that they’re worse at maths than their counterparts (同龄人) in China’s Hong Kong and Finland. “I don’t need it,” my student says, “I’m going to be a basketball star.” Or a car mechanic, or a singer.

Middle school students’ maths skills were tested by the International Organization for Economic Co-operation and Development. The United States ranked 28th out of 41 countries tested. After all, when was the last time you used algebra (代数)？

But maths isn’t just about training Americans to become scientists. It has its own value. It helps you see patterns and develops your logic skills, and it teaches you to concentrate and to separate truth from falsehood. Maths helps you make wise financial decisions, so you can avoid false claims from advertisers, politicians and others. It helps you determine risk. For example, after an airplane crash, studies show that people are more likely to drive than to take a plane in spite of the fact that they are much more likely to be killed or injured while driving. Planes are not like criminals who repeat the same crime over and over. One plane is not more likely to crash just because another plane recently did. In fact, the most dangerous time to drive is probably right after a plane crash because so many people are on the road.

It is not possible to really understand science and the scientific method without understanding maths. A rainbow is even more beautiful and amazing when we understand it.

The precision (精确性) of maths helps us think in a very special way. How do we bring the learning of maths back to life? I don’t have the big answer. I try my best to help pupils find answers to some maths problems. When I can get one to say, “Wow, that’s great,” I feel the joy of a small victory.

1.Some American students don’t care about their poor maths results because __________.

A. maths is useless to most people

B. they have no interest in maths

C. they think maths has nothing to do with their future

D. they don’t do well in maths

2.The example in Paragraph 3 is used to show __________.

A. every coin has its two sides

B. we should not be cheated by fault facts

C. maths is close to our daily life

D. a simple fact shows complicated rules

3.The writer would agree that __________.

A. it’s normal that America kids are weak in maths

B. without maths we’ll miss much in our life

C. maths is the most important subject at school

D. American kids don’t work hard at school

4.This text is most probably written by __________.

A. a student career guide             B. a researcher on students’ problems

C. a specialist in students’ studies      D. a maths teacher

Owning a smartphone may not be as smart as you think. It may let you surf the Internet, listen to music and snap photos wherever you are…but it also turns you into a workaholic, it seems.

A study suggests that, by giving you access to emails at all times, the all-singing, all-dancing mobile phone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles.

The study by technology retailer Pixmania reveals the average UK working day is between 9 and 10 hours, but a further two hours is spent responding to or sending work emails, or making work calls. More than 90 percent of office workers have email-enabled phones, with a third accessing them more than 20 times a day. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers confess(承认) they are on call almost 24 hours a day, with nine out of ten saying they make work emails and calls outside their normal working hours. The average time for first checking emails is between 6 a.m. and 7 a.m., with more than a third checking their first emails in this period, and a quarter checking them between 11 p.m. and midnight.

Ghadi Hobeika, marketing director of Pixmania, said, “The ability to access literally millions of apps, keep in contact via social networks and take photos and video as well as text and call has made smartphones invaluable for many people. However, there are drawbacks. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people literally cannot get away from work. The more constantly in contact we become , the more is expected of us in a work capacity(容量).”

1.What can we conclude from the text?

A. All that glitters is not gold.

B. It never rains but pours.

C. Every coins has two sides.

D. It’s no good crying over spilt milk.

2. The underlined word “accessing” in the third paragraph can be replaced by “________”.

A. calling　　　 B. reaching　　　 C. getting　　 D. using

3.Which of the following is true according to the text?

A. The average UK working time is between nine and twelve hours.

B. Nine- tenths spent over three hours checking work emails.

C. One-fourth check their first mail between 11 p.m. and midnight.

D. The average time for first checking emails is between 6 a.m. and 8 .am ..

4.What’s the main idea of the text?

A. Workaholics like smartphones.

B. Smartphones bring about extra work.

C. Smartphones make our life easier.

One of the biggest social issues in Japan is the increasingly low marriage rate among young people and the small birth rate, which led to an aging and eventually shrinking（萎缩） population. Most young Japanese women simply don’t seem interested in having many children.

Now what began in Japan is happening globally. As David Brooks wrote, birth rate is becoming smaller in much of the world, from Iran — 1.7 births rate per woman — to Russian, where low birth rates connected with high death rates mean the population is already shrinking. And this includes US, which has long had higher birth rates than most developed nations. Aging countries will face the burden of caring for large elderly populations without a larger resource of young workers.

It’s true that global aging is going to present some major challenges. Who will take care of the elderly? Will an older world be less active and slower to change and adapt? It’s all true. Sometimes I worry about a coming generational war over resources, just as I worry about how I will take care of my own parents in their old age, just as I worry about who might take care of me.

But here’s the thing: an older world may have less pressure on the environment. As we all know, the environment is the real victim of overpopulation.

So maybe a world that grows slower and grows older will put less pressure on the environment, and buy us a few more years to ensure our energy use, along with our birthrates, reaches a sustainable（可持续的）level. After all, we’re supposed to get smarter as we got older. Hopefully that holds true for the planet as well.

1.The population issue in Japan was mentioned to ________.

A. show young people’s preference to marriage

B. introduce the topic of global birth rate becoming smaller

C. indicate the deeper cause of Japan’s depression

D. emphasize the revolution of Japanese women

2.Which of the following statements is TRUE according to David Brook?

A. The birth rates all over the world are becoming smaller.

B. The most developed countries have higher death rates.

C. America is the only developed country with higher birth rate.

D. Birth rate’s becoming smaller means a great risk to aging countries.

3.Which will be caused by low birth rates according to the passage?

A. Aging society. B. Environmental problems.

C. High death rates. D. Low employment rates.

4.What’s the author’s attitude to the worldwide birth rates becoming smaller?

A. Anxious. B. Disappointed.

C. Hopeful. D. Doubtful.

The rise in smartphones (智能手机) among young people may be having a direct effect on how successful they become as adults.

Research from the University of Nebraska Lincoln has discovered university students check their phones 11 times per lesson on average, and more than 80 percent believe this tech addiction is interfering with their learning.

A quarter of students across five American states also blamed poor grades in exams specifically on the fact that they used mobile devices when they should have been concentrating and revising and these grades could determine the jobs they end up going into.

Barney McCoy, an associate professor of broadcasting at the university, surveyed 777 students at six universities across five states about how they used digital devices in the classroom.

The students were from UNL, the University of Nebraska Lincoln at Omaha in Nebraska, Morningside College in Iowa, the University of North Carolina, the University of Kansas and the University of Mississippi.

Around two thirds said they used phones, tablets and laptops for ＂non-classroom purposes＂ up to ten times during a typical university day, while 15 percent admitted this figure was closer to 30 times.

Among the top reasons why 55 percent of students checked their devices so regularly were staying connected and fighting boredom. Less than half said the devices were used for classwork.

Texting was the most popular distraction (娱乐) technique at 86 percent, while 68 percent said they used their phones to check personal emails. Two thirds used social networks, 38 percent surfed the web and 8 percent admitted playing games when they should have been studying.

Despite eight out of ten students admitting their devices were distracting, fewer than five percent considered it to be a ＂very big＂ distraction.

＂I don’t think students necessarily think it’s a big problem,＂ said McCoy. ＂They think it’s part of their lives.＂

1.The majority of the students think that using smartphones __________.

A. helps to improve their grades

B. contributes to their poor grades

C. has a bad effect on their study

D. determines their jobs in the future

2. How many students surveyed used digital devices for ＂non-classroom purposes＂ about 30 times during a day?

A. About 518.　　 　　　　 B. About 116.

C. About 427.　　 　　　　 D. Less than 388.

3. Which of the following is TRUE?

A. Barney McCoy surveyed 777 students at the university he works in.

B. A minority of the students said they used digital devices for classwork.

C. Around two thirds admitted they used digital devices because lessons were boring.

D. Barney McCoy doesn’t think students’ using digital devices is a big problem.

4.The text is most likely to be found in a section about __________.

A. successful people　　　　　 B. political systems

C. science and technology　　　　 D. historical events
