[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.According to the passage, when is the most dangerous time for skiers
A. When the temperature is below 20 degrees F
B. Right before a snowstorm
C. During a snowstorm
D. In the winter

[单项选择]
Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-mom to make offers, or "bids", for the various items on sale. He encourages buyers to bid higher figures, and finally names the highest bidder as the buyer of the goods. This is called "knocking down" the goods, for the bidding ends when the auctioneer bangs a small hammer on a table at which he stands. This is often set on a raised platform called a rostrum.
The ancient Romans probably invented sales by auction, and the English word comes from the Latin auctio, meaning "increase". The Romans usually sold in this way the spoils taken in war; these sales were called sub basra, meaning "under the spear", a spear being stuck in the ground as a signal for a crowd to gather. In England in the eighteenth and nineteenth centuries goods were often sold "by the candle": a short candle was lit by the auction

C. to keep the auctioneer warm
D. to limit the time when offers could be made
