A new study finds that more than eighty percent of Internet users in the United States search of health information online.

Susannah Fox from the Pew Internet Project says doctors are still the main source of health information. But the study found that searching online is one of the leading ways that people look for a second opinion. He says, “People are sort of fact-checking what they have heard from a doctor. Our studies show that people are still very likely to turn to a health doctor when they need a diagnosis (诊断) or are planning a treatment.”

Forty-four percent of people are actually looking for doctors or other providers when they search for health information online.　 Two-thirds of Internet users look online for information about a certain disease or medical condition.

The Internet has also become an important source of spiritual support for people with health problems. Susannah Fox says one in five Internet users has gone online to find other people who have the same condition.　

A disease is considered uncommon if it affects(侵袭) fewer than 200,000 people worldwide. The rise of social networking has made it easier for people with uncommon diseases to connect with each other and feel less alone. Social networking is also changing the way some doctors and patients communicate with each other.

Dr. Jeff　 Livingston operates a medical center for women in Irving, Texas. His office uses password-protected software to share information with patients. He says the software has increased efficiency(效率)， reduced costs and improved relations with patients. It has just changed the way we do health care. His medical centre also has a Facebook page, a Myspace page and a Twitter feed.

1._______is one of the most popular ways people look for health information.

A. Asking their Parents B. The Pew Internet Project

C. Searching online D. Reading books on medicine

2.What makes people search for health information online?

A. Peoples interests in health. B. People’s health condition.

C. Importance of the Internet. D. The rise of online treatment.

3.From the fourth paragraph we know that __________.

A. people with health problems go online to look for the new treatment

B. people with health problems try to share their experience with others online

C. people with health problems encourage each other online to fight against diseases

D. Internet becomes a place for people with health problems to reduce worries

A. becomes a new way for doctors and patients to communicate with each other

B. encourages people to get more help from doctors online in time

A new study finds that plants communicate with one another to warn of danger.

We often consider plants as the furniture of the natural world. They don’t move; they don’t make sounds；they don’t seem to act on anything. But as is often the case, plants talk to each other all the time. And the language is a chemical (化学物质).

Over the years, scientists have reported that different types of plants, from trees to tomatoes, give out chemicals into the air to help neighbouring plants. These chemical warnings can spread information about one plant’s disease or infestation (虫害)，so other plants can protect themselves. But how plants receive and act on the information exactly is still mysterious (神秘的）.

In this week’s Science Magazine, researchers in Japan offered some explanations. They have found out one chemical message and traced it all the way from beginning to end.

The scientists looked at tomato plants infested by a common pest (害虫）. To start out，they grew plants in two separate plastic spaces connected by a tube (管子）. One plant was infested and placed upwind and the other was uninfested and placed downwind. The downwind plants were later exposed (暴露的）to the pest. The results showed that plants near sick neighbours before were able to protect themselves better against the pest.

They found one chemical appeared more often in the exposed plants. The chemical is called HexVic. The scientists discovered where HexVic came from, and put it over healthy plants. Those plants were then able to produce HexVic. Researchers made sure that uninfested plants could fight off bugs and diseases. How do they know when to protect themselves? They are warned first by their friendly plant neighbours.

It is not a simple story , and it may be happening in many other plants besides tomatoes. It may also be happening with more chemical signals that are still unknown to us. In a word, we know that plants not only communicate, but also look out for one another.

1.The underlined word “traced” in the fourth paragraph probably means _______here.

A. reported　 B. followed　　 C. doubted　 D. developed

2.For scientists, which are the right steps to watch tomato plants infested by a pest?

① Place the infested plant upwind.

② Place the uninfested plant downwind.

③ Expose the downwind plants to the pest.

④ Grow plants in two separate plastic spaces connected by a tube.

A. ③①②④　 B. ①④③②

C. ④①②③ D. ④②①③

3.You can put the sentence “The researchers also studied leaves from exposed plants and unexposed plants. " at the beginning of Paragraph ____.

A. 3　　　 B. 4　　 C. 5　　　 D. 6

4.Which of the following can be the best title of this passage?

A. Communicating Plants and Terrible Diseases

B. Talking Plants and Friendly Warnings

C. Protecting Plants and Clear Information

D.　 Growing Plants and Mysterious Chemicals
