2 . The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language and connect with family and friends.

As far as the Internet being a part of our lives —well, that train has left the station. This expression means there is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers.

A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group— teenagers. The study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure. High blood pressure can cause heart and kidney (肾) disease. It is also closely linked to some forms of dementia (痴呆), a brain disease. Dementia is marked by memory disorders, personality changes, and a reduced ability to reason.

The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people from 14 to 17 years old participated in it. One hundred and thirty-four of the teens were described as “heavy Internet users.” Researchers found that out of these 134 teens, 26 had high blood pressure.

The lead researcher of the study is Andrea Cassidy-Bushrow. In a statement she said, “Using the Internet is part of our daily life but it shouldn’t consume us.” For the purpose of the study, she explains, teens considered heavy Internet users were online on “average 25 hours a week.” Ms. Cassidy-Bushrow adds that it is important for teens to take “regular breaks from their computers or smartphones” and to do some “kind of physical activity.”

1. Which of the following statements is closest in the meaning to the underlined sentence in Paragraph 2?

A．The train has stopped at the wrong station.

B．There is something wrong with the train.

C．Life without the Internet is nowhere to be found.

D．The train has changed its course.

2. If a person suffers from Dementia, he _______.

C．will develop a brain cancer	D．can do analysis accurately

3. What is the percentage of young “heavy Internet users” with high blood pressure?

A．40%

B．19%

C．25%

D．7%

4. Which of the following is the best title of the passage?

D．High Blood Pressure Is around the Comer.

3 . “When studying foreign speech, don’t forget about body language. ” Anne Merritt said.

Something as simple as a smile can show: friendliness in one culture, embarrassment in another, impatience in a third. Even silence means different things in different places. If you want to avoid making some mistakes when traveling abroad, you should pay attention to the following.

Touch     

Britain, along with much of Northern Europe and the Far East, has a “noncontact” culture. In those countries, there is very little physical contact (接触) in people’s daily talks. Even brushing someone’s arm by accident is the reason for an apology. However, in the high-contact cultures of the Middle East, Latin America, and Southern Europe, physical touch is a big part of daily life.

What’s more, there are different standards, for who touches whom and where. In much of the Arab world, men hold hands and kiss each other in greeting, but would never do the same with a woman. In Thailand and Laos, it is taboo (禁忌的) to touch anyone’s head, even children’s. In South Korea, elders can touch younger people with force when trying to get through a crowd, but younger people can’t do the same.

Eye contact     

In most Western countries, frequent eye contact: is a sign of confidence and attentiveness (注意). We may think that a conversation partner who looks away is either not listening to us or lying. Of course, this is not the standard around the world.

In many Asian, African, and Latin American countries, the unbroken (未间断的) eye contact would be considered impolite and rude. These cultures consider avoiding eye contact a sign of respect for bosses and elders. In these parts of the-world, children won’t look at an adult who is speaking to them, nor will employees look at their bosses.

1. In Britain, when people are talking, they usually_________.

A．avoid eye contact	B．brush the others’ arms
C．avoid physical contact	D．apologize for their mistakes

2. In Southern Europe, physical touch is________.

A．unnecessary

B．impolite

C．dangerous

D．common

3. What does this passage mainly tell us?

A．How to have a good time abroad.	B．The importance of body language.
C．How to communicate with foreigners.	D．An introduction to some body language.

4 . Is It Worth Buying Organic Food?

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.

The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”

For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

1. The new research questions whether organic food ________.

A．should replace traditional food

D．Traditional fruit and vegetables.

4. What is the author’s attitude toward organic food?

6 . You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

Jane Addams (1860-1935)

Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community (社区) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.

Rachel Carson (1907-1964)

If it weren’t for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world’s lakes and oceans.

Sandra Day O’Connor (1930-present)

When Sandra Day O’Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator (参议员) and, in 1981, the first woman to join the Supreme Court of the United States. O’Connor gave the deciding vote in many important cases during her 25 years on the top court.

Rosa Parks (1913-2005)

On December 1, 1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott (抵制).

8 . More than half of the food produced in Canada goes to waste. A shocking new study has shown that the level of food waste is far worse than previously thought, at 58%. Of that, about 85% of food waste is due to food processors. This differs from earlier studies, which criticized families for driving food waste and said they were responsible for 51% of food waste.

The study was carried out by Martin Hooch, the leading expert on food waste and the author of several previous studies on the subject. Reflecting on the study’s findings, Hooch said, “It means stopping criticizing consumers. Sure, consumers are part of the problem, but they’re not the problem.”

In the past, Hooch didn’t master good data, particularly from the private factories, but relied on numbers collected by the food industry for purposes other than tracking waste. This time, however, Hooch worked directly with companies at all stages along the food production chain and interviewed over 700 experts in the industry. Clearly he found it hard to believe what he was seeing.

This is what they found: Food processing causes 34% of food waste. This is followed by production, which causes 24%. Next is manufacturing at 13%, then hotels and restaurants at 9%. Families cause only 14%, and market sales 6%. This should be a scrious wake-up call for Canadians who would do well to examine their own food supply chains. Food waste is costly, not only in terms of dollars wasted, but also in resources like land, water, and so on. To be using these resources and wasting the product is totally irresponsible and unnecessary.

To make matters worse, when food is thrown into rubbish cans, it produces methane, a greenhouse gas 30 times more powerful than carbon dioxide (CO2). At Canada’s rate of food waste, that’s like adding 12 million cars to the road. It seems that the food industry needs redesigning. Therefore, let’s hope the government takes action.

1. What did earlier studies say about food waste in Canada?

A．Families were to blame for food waste.	B．Food went bad when it was processed.
C．Most of the food was wasted on purpose.	D．Food waste was better than expected.

2. How did Hooch do his study on food waste this time?

A．By studying data from the industry.	B．By drawing a conclusion from the previous studies.
C．By collecting advice from experts worldwide.	D．By tracking the whole production chain.

3. Why does food waste have an effect on the environment?

A．Because it is harmful to the trees.	B．Because it produces more greenhouse gas.
C．Because it gives off unpleasant smells.	D．Because it pollutes the soil around it.

4. What is the main idea of the text?

A．Canadians don’t like to save food for future.

B．Families are mainly responsible for food waste.

C．More than half of the food is wasted in Canada.

D．The food industry is better redesigned in Canada.

9 . “More and more consumers across the country are using cashless payment methods. The rapid development of third⁃party mobile payment tools is helping to encourage cashless payment across the country,” said Dong Ximiao, a researcher at Renmin University of China.

Although there were 3.4 billion third⁃party payment accounts in total in China in 2016, China is not the first country to seek a cashless society. Developed countries like Sweden, Denmark and Singapore are also seeing that increase.

However, the rapid development of the cashless payment does not mean there are no challenges or criticisms. Alibaba’s Hema store has come under the spotlight (成为焦点) recently. The media said that consumers couldn’t buy goods in cash there, which would be considered illegal.

Alipay and WeChat Pay, the nation’s two major third⁃party mobile payment tools, also launched campaigns this month to encourage more people to use cashless payment methods, which caused concern over whether cash will soon disappear.

“Some offline sellers refuse to accept cash, which influences the natural circulation (流通) of cash,” said Dong. He stressed that a cashless society would not mean that cash would completely disappear. “Also it’s important to remember that nearly half of China’s population live in the country, and they are unable to enjoy innovation (革新) brought by the Internet,” said Dong. “And when it comes to China’s senior citizens, most of them prefer to use cash in their daily lives,” he added.

“It’s ridiculous (荒谬的) to question digital payment tools’ contribution to financial development. In the long term, various payment methods will be used by consumers, and merchants should respect consumers’ payment habits,” Dong noted.

1. What does the underlined word “that” in Paragraph 2 probably refer to?

A．The economic activity.	B．A large amount of payment.
C．The development of the economy.	D．The cashless payment.

2. Why has Alibaba’s Hema store become a focus?

A．It fights against illegal activities.

B．Customers are not permitted to use cash there.

C．It provides comprehensive services.

D．It starts campaigns to encourage mobile payment.

3. What is Dong Ximiao’s attitude towards the payment in the future?

A．The cashless payment should be limited in the countryside.

B．The innovation from payment is ridiculous in fact.

C．Various payment methods should be supported.

D．The digital payment should replace cash completely.

4. What is the best title of the passage?

A．Innovation on the Internet	B．Cash or cashless?
C．Payment online should replace cash	D．Is the circulation of cash dying?
