[单项选择]There are few more sobering online activities than entering data into college-tuition calculators and gasping as the Web spits back a six-figure sum. But economists say families about to go into debt to fund four years of partying, as well as studying, can console themselves with the knowledge that college is an investment that, unlike many bank stocks, should yield huge dividends(红利).
A 2008 study by two Harvard economists notes that the "labor-market premium (额外收益) to skill"—or the amount college graduates earned that’s greater than what high-school graduates earned—decreased for much of the 20th century, but has come back with a vengeance (报复) since the 1980s. In 2005, the typical full-time year-round U.S. worker with a four-year college degree earned $50900, 62% more than the $31500 earned by a worker with only a high-school diploma.
There’s no question that going to college is a smart economic choice. But a look at the strange variations in tuition reveals that the choic
A. Huge amounts of money is being wasted on campus socializing.
B. It doesn’t pay to run into debt to receive a college education.
C. College education is rewarding in spite of the startling costs.
D. Going to college doesn’t necessarily bring the expected returns.

[单项选择]Few natural dangers are more feared than avalanches. Avalanches are a familiar part of European history. Particularly in the Swiss and French Alps. This is where the direction of wars has turned almost instantly because of avalanches wiping out invading armies. In North America, avalanches are limited almost entirely to the Rocky Mountains and the lower ranges to the west, the Sierra Nevadas and the Cascades. Avalanches have occurred in the mountains of New England but not with the regularity and intensity seen in the western mountains. Several methods are used in explaining and predicting avalanches. Scientists are learning about them using research methods. So many of the factors that create avalanches are hidden beneath the snow"s surface that predictions are still largely guesswork. Therefore, winter travelers must assume the worst of conditions when they traverse the slopes. An avalanche occurs when a given amount of snow becomes too heavy for whatever is holding it in place. It then breaks loose and slides downhill. Avalanches are divided into two general categories, loose snow and slab. A loose snow avalanche usually starts at a single point, such as a skier"s track, and spreads out like a fan or a pyramid in a chain reaction. One crystal breaks another free, which multiples as the loose snow moves downhill. Sometimes these avalanches stop after only a few feet. Sometimes they move thousands of tons of snow downhill in speeds up to 300 miles per hour. This creates a shock wave that can flatten parts of a forest that are not even touched by the actual avalanche. Stab avalanches are those that have a wide area of snow which breaks loose in a large piece. These can range in size from just a few square feel to thousands of square feet of snow. The most dangerous and common type of avalanche for skiers is the so-called "soft slab" avalanche. This type occurs most often during, or just after a heavy snowfall. The snow hasn"t yet had a chance to settle and adhere to the existing snow. The heavier and the wetter the snow and the colder the temperature, the less likely the new snow will form a bond with the existing snow.What would be the best title for this passage
A. Avalanches
B. The History of Avalanches
C. Skiers Beware
D. Avalanches Can Kill

Few numbers tell a happier story than those that measure life expectancy. An American born in 1900 could expect to live 47 years. Thanks to colossal improvements in sanitation and medicine, that figure is now 75 for men and 80 for women. (71)
So it is both alarming and surprising when life expectancy falls, even for a small part of the population. Yet that is what some researchers at Harvard have found. They looked at death rates by county, having corrected for migration and merged sparsely populated ones so that America’s 3,141 counties became 2,068 "county units".
(72) But between 1983 and 1999, it fell significantly (by about a year) for women in 180 county units, and stagnated in another 783. Men fared less poorly, their life expectancy fell significantly in only 11 county units, and stagnated in another 48.
Put differently, life expectancy appears to have either stagnated or fallen slightly for some 4% of American men

Few gifts are more cherished than a trip, but there are some pitfalls to surprise a loved one with a voyage.
