【解析】With the development of science, the Internet comes into our everyday life. It helps us in many ways. Shopping is a good example. We can buy the things we want on the Internet without leaving our house. We don't need to hunt for them shop by shop. Shopping on the Internet can save us a lot of time. What's more, the goods may be even cheaper than those in shops. All we have to do is to search for the goods we want and click, and then just wait.

Though it is convenient and fast to shop on the Internet, there is still something for us to worry about. Quality is a big problem. We can't see the real goods on the Internet. After all, we can't choose them ourselves. Besides, lots of advertisements on the Internet are not reliable. So sometimes we are easily cheated.

Therefore we should be careful while we're enjoying the convenience of high technology.

【题目】Everyday we talk about and use the Internet, but how many of us know the history of the Internet?

Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer network didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time.

At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" in the Internet more convenient.

Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students. The Internet has now become one of the most important parts of people's life.

【题目】D

Dogs can be trained to identify the smell of lung cancer long before symptoms develop.

A new study is the first to show that sniffer dogs can be relied upon to find the unique smell of the disease of in 7 out of 10 sniffers. Researchers from a hospital in Germany believe dogs could become even better at picking out cancer cases with more training, but the final goal is to identify the cancer-specific chemical compounds the dogs can smell, and develop a device that could be used to help diagnose lung-cancer victims at an earlier stage.

Lung cancer is Britains deadliest cancer, with over 39.000 cases diagnosed annually, of which only 25 percent will survive for a year, since the disease is mostly found at an advanced stage, when it is very difficult to treat. Early detection is often by chance, although scientists have been working on using samples of exhaled(呼出的) breath from patients for future screening. They attempt to use the samples to locate volatile organic compounds(VOCs) in the breath that are linked to the presence of cancer, but no reliable methods have been found so far that are lung-specific.

The researchers combined this approach with recent findings about the abilities of some dogs to alert their owners to undiagnosed cancer, probably through smell. This latest study used family dogs, which were given special training over an 11-week period to identify a VOC in the breath of patient.

The researches worked with 220 volunteers, including patients with lung cancer at early and advanced stage, patients with chronic pulmonary disease(慢性肺炎), and healthy volunteers. The dogs took part in a number of tests to see if they could reliably distinguish compounds in the breath of lung-cancer patients-even if they smoked. The dogs were asked to sniff glass tubes containing cotton impregnated(浸染) with samples of breath from those taking part and had to lie down if they detected a VOC from a lung cancer patient.

The dogs successfully identified 71 samples with lung cancer out of a possible 100. They also correctly detected 372 samples that did not have lung cancer out of a posible 400.

【1】What can we conclude from the research according to the passage?

A. The volunteers included patients with various cancer successfully

B. It used police dogs specially trained over a period.

C. It aimed to see if dogs could sniff cancer-specific compounds.

D. The dogs identified 372 samples with lung cancer successfully.

【2】We can infer from the passage that a VOC is probably a kind of _____.

A. liquid B. drug C. equipment D. chemical

【3】Which of the following is Not true according to the passage?

A. The research involved about a hundred dogs in all.

B. Dogs can usually detect the lung cancer patients well.

C. There are about 39,000 lung-cancer patients in Britain every year.

D. Lung cancer is Britains biggest cancer killer.

【4】What can be the best title of the passage?

A. A New Way to Treat Cancer

B. A New Way to Detect Disease

C. Dogs Can Sniff out Cancer

D. Dogs Can Protect People from Cancer
