Fifteen percent of US teenagers aged 12 to 17 who own mobile phones have received nude or

nearly nude images of someone they know, according to a survey released on Tuesday. Only four percent of mobile phone-owning teens in that age group have sent sexually suggestive pictures of themselves, a practice known as "sexting," according to the Pew Research Center's Internet American Life Project.

The Pew survey found that girls and boys were equally as likely to have sent a suggestive picture to another person and older teenagers were more likely to have engaged in "sexting." Eight percent of 17-year-olds with mobile phones have sent a sexually provocative image by text and 30 percent have received a nude or nearly nude image on their phone. Only four percent of 12-year-olds have sent suggestive images of themselves.

Amanda Lenhart, a senior research specialist at Pew and the author of the report, said sexually suggestive images have become a form. of "relationship currency" for teens. "These images are shared as a part of or instead of sexual activity, or as a way of starting or maintaining a relationship with a significant other," she said. "And they are also passed along to friends for their entertainment value, as a joke or for fun." "The desire for risk-taking and sexual exploration during the teenage years combined with a constant connection via mobile devices creates a 'perfect storm' for sexting," said Lenhart. "Teenagers have always grappled with issues around sex and relationships, but their coming-of-age mistakes and transgressions have never been so easily transmitted and archived for others to see," she added.

The survey found that teens with unlimited text messaging plans were more likely to receive "sexts" containing images of people they know. About 75 percent of mobile phone owning teens have unlimited plans. Among this group, Pew said 18 percent reporting receiving "sexts" compared with eight percent of teens on limited data plans and three percent of teens who pay per message. According to Pew, 58 percent of 12-year-olds own a mobile phone and 83 percent teens aged 17 do.

Pew noted that a number of US states are grappling with how to deal with "sexting" among minors and some legislatures have stepped in to consider laws that would downgrade charges from felonies to misdemeanors. Pew conducted telephone interviews with 800 teens aged 12 to 17 and their parents between June 26 and September 24.

er market. In 1984, however, ibuprofen was expected to account for fifteen percent of all nonprescription pain-reliever sales.

The prediction mentioned in the last sentence above was based on which of the following assumptions？

听力原文： Around the world, about one-hundred-sixty thousand children under age fifteen ar
e found each year to have cancer. The researchers say eighty-four percent of these cases are found in developing countries. They say only ten percent of children with cancer in these countries survive and many more could be saved if their countries had the resources needed to find cancers and treat them. Children from industrial countries like Britain and the United States who develop cancer have a much better chance to survive.

听力原文： Kuwait is a country which is quite small, but which is very rich. It has a popul
ation of a little more than a million, and it is situated at the North end of the Persian Gulf. This small desert country is one of the world's leading oil producers, and it has approximately fifteen percent of the world's leading oil producers, and it has approximately fifteen percent of the world's known petroleum reserves. Since the discovery of oil in 1938, Kuwait's rules have turned the country into a prosperous welfare state. It has free primary and secondary education, free health care and social services; and the Kuwaitis do not have to pay any personal income tax for those services. The rate of literacy is high and constantly growing. The University of Kuwait was opened in 1966, but many of the Kuwaiti students still study in colleges and universities abroad, at state expense. Kuwait is, needless to point out, an Arab country, and about 99 percent of the people who live there are Moslems. But fewer than half of these Moslems are actually citizens of Kuwait. This is because there are many Moslem immigrants living and working there. Many of these recent immigrants have come from all over the Arab world—from places like Egypt, Syria, Lebanon，from Oman, and from the Sudan. Indians, Pakistanis, and Iranians live and work in Kuwait, too. The other one percent of the population, in other words, the non Moslems, are recent immigrants who were attracted by the opportunities to work for the oil companies. There are several thousand Europeans and Americans in Kuwait. Many of them are employed by the oil companies.

听力原文：There are new findings that people with inadequate sleep are likely to gain weigh

听力原文： There are new findings that people with inadequate sleep are likely to gain weight. Researchers say a lack of sleep can produce hormonal changes that increase feelings of hunger.

In one study, researchers from Stanford University in California and the University of Wisconsin examined information on more than one thousand people. The people had taken part in a long-term study of sleep disorders.

Some people slept less than five hours a night. They had fifteen percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had fifteen percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.

The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight.

Researchers found that the best amount of sleep for weight control is seven-point-seven hours a night.

Researchers at the University of Chicago did a smaller study. They found that people who slept just four hours a night for two nights had an eighteen percent reduction in leptin. And they had a twenty-eight percent increase in ghrelin. The young men in that study also appeared to want more sweet and starchy foods.

Researchers from Columbia University in New York did a third study. They found that people who got less than four hours of sleep a night were seventy-three percent more likely to be overweight. This was compared to people with seven to nine hours of sleep. The researchers say that for survival, the body may be designed to store more fat during times with less sleep.

According to the passage, how many universities in the United States took part in the study？

A．Four.

B．Three.

C．Five.

D．Six.
