"Children should not be left unsupervised (无人监督的) to play with a dog." say experts in this week's British Medical Journal. Their advice is part of a review aimed at doctors who deal with dog bites.
"Dog bites and maulings are a worldwide problem, particularly in children." write Marina Morgan and John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some time, boys more than girls.
Accurate death figures are difficult to obtain, but in the past five years, two to three cases a year have made news headlines.
Based on the latest medical evidence, they advise doctors how to examine and treat a patient presenting with a dog bite. They discuss the risk of infection and when to refer to specialist care. For travelers bitten abroad, they suggest assessing the risk of rabies(狂犬病).
In terms of prevention, they suggest that children should be taught to treat dogs with respect, avoid direct eye contact, and not tease them. They should be taught not to approach an unfamiliar dog; play with any dog unless under close supervision; run or scream in the presence of a dog; pet a dog without first letting it sniff you; or disturb a dog that is eating, sleeping, or caring for its babies.
"Dog owners also need to change their behavior", says Rachel Besser, a children's doctor and lifetime dog owner, in an article.
"It is clear that not all dog owners appreciate that children should not be left unsupervised with a dog", she says. Just as some parents are obliged to take parenting classes, she would like to see compulsive classes for expectant dog owners to teach them about the responsibilities of dog ownership. Educational programs are also needed to teach children about some precautionary （预防的) behaviors around dogs.
Finally, she would like to see animal doctors advising dog owners about bite prevention, and doctors promoting bite prevention when treating patients who have been bitten by dogs.

That year, Steve Wozniak returned to college and Steve Jobs left in a dispute with the chief executive.
Mr. Jobs then formed his own company, called NeXT Computer. He rejoined Apple in 1997 after it bought NeXT, He helped remake Apple from a business that was in bad shape then to one of the most valuable companies in the world today.

[1]Online advertising is simply advertising that is done on the Internet. While it has a much shorter history than traditional advertising, the effects of online advertising can not be undervalued As more people turn to the Internet as a source for daily news, socialization and communication, more advertising dollars are likely to be spent. In fact, in a period of five years, from 2006 to 2010, online advertising 6 percent of all money spent for advertising, to 12 percent or more.
[2]Online advertising is also quickly becoming a serious force for other types of advertising media to deal with. Newspapers and magazines all over the world are facing a number of different challenges, including loss of ad revenue (广告收益). Many attribute (把……归于) some of those struggles to online advertising, which is not only taking a share of the advertising, but a share of the audience as well.
[3]However, newspapers and magazines are not the only media dealing with lower revenue. The remarkable thing about online advertising is it gives the ads a much wider coverage and its globally wider coverage helps in making the advertisements reach more audiences. Furthermore, because of hypertext (超文本) linking, advertisers have the power to transport potential buyers directly to their site.
[4]Online advertising can be presented in many flexible styles. In some cases, it may not look like advertising at all. There was one case. A video that showed popcorn (爆玉米花) being popped by radiation which was put out from mobile phones was put on the website. While this was later revealed as a trick, the company that put the video online received a large amount of attention. The company sold earphones meant to help limit an individual’s exposure to radiation.

Half a century after the March of Dimes (a US charity organization that collects money for children) put the 20th century’s most feared childhood disease on the road to eradication (根除), Bill Gates declared polio (小儿麻痹症) his important job and challenged world leaders to finish the job.
India, Nigeria, Pakistan and Afghanistan now have active transmission (传播) of the disease. Gates says the biggest problem with the success of the Global Polio Eradication program in those countries and elsewhere is lack of money.
The Bill and Melinda Gates Foundation plans to increase its $200 million annual contribution (每年的捐款) by $102 million this year, Gates says. Gates recently met privately with Pakistan’s President in Washington, D.C., to try to persuade him to provide full support for Pakistan’s eradication plan.
Children in the USA also are at risk, experts say. Parents who don’t vaccinate (给某人接种疫苗) their children because they are fearful of vaccine side-effects create a large number of children who are likely to be harmed by the virus.
“If you increase the number of unvaccinated children, you increase the chance that this virus will find new subjects,” says David Oshinsky, Pulitzer Prized-winning author of Polio: An American Story.
“We’ve got to get this vaccine into the mouths of children,” says Bruce Aylward, head of the World Health Organization’s eradication program.
In 1988, when the World Health Organization launched the Global Polio Eradication program, the disease killed 350,000 children a year worldwide. By last year, the total dropped to fewer than 1,500 worldwide, Aylward says.
If Gates provides the final push for polio eradication, he may be remembered as much for helping prevent polio as for founding Microsoft, Oshinsky says.
“As long as there’s polio anywhere, people everywhere are at risk,” Aylawrd says. “We’re still not out of the woods.”
According to the text, the success of the Global Polio Eradication program mainly depends on .

A．the World Health Organization’s policy

B．the development of a new vaccine

C．the local governments’ support

D．the collection of funds.

C．Great progress has been made in preventing it.

D．There are few organizations helping to prevent it.

According to Oshinsky, .

A．Gates should devote more time to Microsoft

B．polio eradication is a very important cause

C．vaccine side-effects should not be ignored

D．polio has been brought under control

According to the passage, which of the following about Bill Gates is TRUE?

A．He is the founder of the Global polio Eradication program.

B．He persuades some of the world leaders to support the eradication plan.

C．His foundation contributes $302, 000 to eradicate polio every year.

D．He works harder on preventing polio than founding Microsoft.
