【题目】Survey Studies Internet Use in China

A typical(典型的) Chinese Internet user is a young male who prefers instant messaging to e-mail, seldom makes online purchases(购买) and favors news, music and games sites. According to a study, about two-thirds of survey participants use the Internet for news often entertainment-related or for online games. About half download music and movies.

They also tend to prefer instant messaging to e-mail, and they are depending on the Internet more frequently than before to communicate with others who have the same professions, hobbies and political interests. Online purchases still remain unpopular in China. Three-quarters of users surveyed have never bought anything over the Internet, and only 10 percent make purchases even once a month. Among those who do buy online, most pay for entertainment while others buy phone cards, or computer hardware or software.

“Many people don’t trust the quality of goods bought online,” Guo said Wednesday. “If they buy it in a store and don’t like it, they can easily bring it back.”

The survey was done in five major cities: Beijing, Shanghai, Guangzhou, Chengdu and Changsha. Results do not necessarily project countrywide because Internet use in rural areas is lower than in cities. Guo describes the typical netizen in the five cities surveyed as young, male, richer and more highly educated. Males make up two-thirds of the Internet community, and more than 80 percent of users are under. Among people ages 25 to 29, 60 percent to 80 percent go online.

China has more than 100 million people online, second in the world to the United States.

【1】 A typical Chinese Internet user will be the one who ______.

A. likes to buy goods online

【2】Online purchases still remain unpopular in China mainly because ______.

【题目】Scientists have discovered a special biological behavior in dolphins(海豚) that could lead to a treatment for late-onset diabetes(晚发的糖尿病) in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning.

The extraordinary finding has led scientists to suggest that dolphins have genetic switch that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect.

If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity(肥胖).

The tissues of people with type 2 diabetes have become resistant to insulin(胰岛素)so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys(肾脏) and nerves and contribute to 5% of all deaths, according to the World Healthy Organization.

Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson’s team analyzed 1,000 blood samples(样本) from 52 dolphins while they didnt eat anything overnight and fed in the morning. At night time, the dolphins’ metabolism(新陈代谢)changed greatly and showed similar characteristics to that seen in people with type 2 diabetes.

“It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans,” said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.

【1】Whats the main idea of the passage?

A. Humans get some idea of treating diabetes from dolphins.

B. Dolphins can switch into a diabetic-like state overnight.

C. Humans can suffer the same disease as dolphins.

D. Dolphins should be fed regularly to avoid diabetes.

【2】The key to applying the finding to curing human diabetes lies in ____________.

A. producing insulin in a larger amount

B. developing drugs from healthy dolphins

C. identifying a similar genetic pathway in human

D. analyzing more blood samples from hungry dolphins

【3】 Which of the following statements is TRUE according to the passage?

A. Scientists have found a similar genetic switch in humans.

B. More British people will suffer type 2 diabetes due to obesity.

C. 2.2 million people with type 2 diabetes die in Britain every year.

D. Dolphins imitate diabetes to avoid a high blood sugar level.

【4】What will happen to dolphins if not fed for a night according to Venn-Watson?

A. Their metabolism breaks down.

B. They become resistant to insulin.

C. Their heart and kidneys are damaged.

D. They keep high levels of blood sugar.

【题目】Easy way to get healthy

I always hate the first few weeks of the New Year, mostly because people all say, “Let’s diet! It’s a new year!“

You can always choose to switch it up! 【1】 Here are some simple ways to get your health on all year round.

Switch out bad habits for good ones. 2 Do something as simple as swapping nighttime cookies for nighttime vitamins.

Catch some sleep. One of the most important things we can do for our minds and bodies is to make sure we’re getting enough sleep on a regular schedule. 3

Feed your mind. Keep your mind smart. Start a new hobby, read a book about something you don’t understand— and so on.

4 I’m not suggesting you take on a new sport. But taking the stairs, parking farther away, and finding a hobby you enjoy will allow you to be active.

Get organized. I’m not saying a whole repair of your entire world; start small. Organize a kitchen cabinet. Purge(清除) yourself of stuff you don’t need.

Get rid of the mess. That means your mind is included too! Make lists. Get a calendar and mark down important days. Clear your mind and your home. 5 .
