Passage 1 Falls are the number one cause of death ...

e Earth's Gravity(重力) pulls it. But every cloud is made of water droplets or ice crystals. Why doesn't rain or snow fall constantly from all clouds？ The droplets or ice crystals in clouds are exceedingly small. The effect of gravity on them is minute. Air currents move and lift droplets so that the net downward displacement is zero, even though the droplets are in constant motion.

Droplets and ice crystals behave somewhat like dust in the air made visible in a shaft(束) of sunlight. To the casual observer, dust seems to act in a totally random fashion, moving about wildly without fixed direction. But in fact dust particles are much larger than water droplets and they finally fall. The cloud droplet of average size is only 1/2,500 inch in diameter. (78)It is so small that it would take sixteen hours to fall half a mile in perfectly still air, and it does not fall out of moving air at all. Only when the droplet grows to a diameter of 1/125 inch or larger can it fall form. the cloud. The average raindrop contains a million times as much water as a tiny cloud droplet. The growth of a cloud droplet to a size large enough to fall out is the cause of rain.

What is the main topic of the passage？

A．The mechanics of rain.

B．The climate of North America.

C．How gravity affects air current.

D．Types of clouds.

o areport published last week. About 8 million cases were treated in emergency department, andapproximately 800,000 seniors went on to be hospitalized. More than 27,000 falls led todeath.(76) And the problem is getting more and more serious.

“Older adult falls are increasing and, sadly, often indicate the end of independence, ” said Dr. TomFrieden. The falls are preventable, Friedenstressed. He said individuals, families and healthcare providers can take steps to resist the trend. Dr. Wolf-Klein is a medical professor in New York.

When that happens, prevention effortsdon’t begin and they’re at risk for additional falls that lead to broken bones and brain injuries.

“Elderly patients tend not to report falls to their families, or even doctors. A fall is a veryfrightening thing that you keep quiet about. They think if they mention it, they are afraid thatthey will move to a nursing home or need assistants to help out in the house, ”said Wolf-Klein. It’s also a status issue and may make someone feel that they’re weaker than they really are,she explained. When someone does fall and hurt themselves, they’re often never the same,Wolf-Klein said. “You can develop chronic(慢性的)problems. After a fall, a percentage of thepopulation will never return to walking around. People used to taking the subway, now they ’re ina wheelchair, or they may need help going to the bathroom. They become frailer and loseindependence,” she said.

ories across a large area of the north-eastern United States and southern Canada. The outcome affected some of the world's biggest and busiest cities, including New York, Detroit, Cleveland and Toronto, leaving up to 60m people without electricity, equivalent to the entire population of France or Britain.

So severe was the disruption (破坏) in New York State that its governor, George Pataki, declared a state of emergency. Confused workers spilled on to the streets, while thousands more were trapped for hours in lifts and hot, crowded subway trains. Lots of stranded (进退两难的) people ended up spending Thursday night on New York's streets. Thieves in Brooklyn in New York, and in Canada's capital, Ottawa, took advantage of the absence of streetlights and burglar alarms, and went on a looting spree (疯狂抢掠). Officials were taken aback by the speed at which the chaos unfolded. President George Bush described the incident as a "massive national problem" and promised a full investigation into what caused it.

That is still a matter of some debate. At first, naturally, there were fears of terrorist involvement, but this was quickly ruled out. However, officials were left arguing about what had actually happened. The office of Canada's prime minister, Jean Chretien, said that a severe accident at a nuclear-power plant in Pennsylvania may have been the cause. Earlier, American and Canadian officials had said a fire or perhaps lightning had hit a power plant near Niagara Falls in New York State.

line of Wal mart clothing was exposed as the work of underpaid laborers in New York City's Chinatown, the Department of Labor and the White House teamed up to condemn such practices. With much fanfare, President Clinton's administration launched the "No Sweat" campaign, which pressured retailers and manufacturers to submit to periodic independent inspection of their workplace conditions.

This campaign urged manufacturers to sign the Workplace Code of Con duct, a promise to serf-regulate that has since been adopted by a handful of retailers and many of the nation's largest manufacturers, including Nike and L.L. Bean. However, the Department of Defense, which has a $1 billion garment business that would make it the country's 14th largest retail apparel outlet, has not signed the Code of Conduct. In addition, it has not agreed to demand that its contractors submit to periodic inspections. Because the Department of Defense has not agreed to adhere to the cede, the job of stopping public sector sweatshops falls to the Department of Labor. Federal contractors that persist in violating wage laws or safety and health codes can lose their lucrative taxpayer financed contracts. But Suzanne Seiden, a deputy administrator at the Department of Labor, says that to her knowledge, the department has never applied that rule to government apparel manufacturers. "I just assume that they are adhering to safety and health requirements," she says. According to records obtained by Mother Jones, through a Freedom of Information Act request, the Occupational Safety and Health Administration has cited Lion 32 times for safety and health violations in the past 12 years.

What is this passage mainly concerned with？

A．The functions of the Department of Labor in America.

B．A serious problem threatening American economy.

C．The successful attempt of regulating sweatshops in America.

D．The seriousness of the problem of sweatshops in America.
