First of all, the winter season usually begins in December and ends in early March. The coldest month is January, and temperatures can drop below freezing for most of this month. The city usually averages about 30 inches of snow during this entire, 3-month period. Occasionally, we have snow storms that can drop a foot of snow in a very short period of time. Winter activities during this season include sledding, skiing, and snowshoeing.
Spring usually arrives in late March, and the temperatures hover around 50 degrees during the day. It is a beautiful season because the flowers start to bloom. It is sometimes, windy, and this is great for flying,kites. People in my city often like to go on picnics, stroll through parks, and play outdoor games.

Four seasons are characteristic of the Gobi: spring, summer, fall, and winter, with usually a false spring at the end of winter. These seasons are distinct, with extremes of temperature, as much as 150 between the hottest day in summer and the coldest day in winter.
Spring in the Gobi usually begins about the second week April. For 2 or 3 weeks there is a period of delightful weather, with warm, sunny days and not too much wind. But these are the days of false spring. About the first of May, the tail end of winter returns, and cold, blustery days of dustburdened winds are the rule then, until early or middle June. The latter part of June, for 2 or 3 weeks after the blowy end of winter is the real spring. It spreads its rather comfortable warmth over the desert, and occasional light rains help the desert grass to come along nicely.
July, or sometimes mid-June to mid-August is summer. Hot days are the rule, but the nights are cool. Wind and dust again govern the desert, but this is the season when hard rains, if they come at all, are most likely to dump water on the plains.
Fall usually may be recognized by the encouraging, bright days beginning in mid-August and lasting until mid-September or the first of October. This is the time of year when both men and beasts feel best in the Gobi. The clear air, bright sun, and frosty temperatures make you glad to be alive.
Winter comes with a rush anytime after the middle of September. One day you may be enjoying a pleasant temperature near the eighties. But suddenly the air cools. In a few hours the temperature has slipped below 50; and a little later cold rain changes to snow and blustering wind.
In this passage the author briefly describes ______.
A.the different seasonal changes
B.the effects of climatic change on msn and beasts
C.the Gobi as a terrible place to live in
D.the seasonal cycle of the Gobi
Passage One
Animals have different ways of protecting themselves against wintertime weather. Some animals grow heavy coats of fur or feathers, while others dig into the ground to find a warm wintertime home.
Some animals spend the winter in a deep sleep because by going to sleep they avoid the time of the year when food is scarce and the temperatures are low. Their sleep is known as hibernation.
There is much about hibernation that puzzles scientists. For example, they are wondering how hibernation came into being. Some scientists have explored the possibility that animals release a chemical that starts them hibernating.
One thing that scientists are certain about is that animals hibernate only when it is cold. Hibernation is a seasonal practice.
Some animals that fall into a wintertime sleep are not true hibernators because they spend only a part of the cold season asleep. Bears, for example, can easily be awakened from their winter nap. They are not true hibernators.
Sometimes it is difficult to determine whether a particular animal is a true hibernator. For example, some mice hibernate, but others do not. The same is true of bats. Some of them hibernate. Others do not.
36. Hibernation is a seasonal practice. This means it ______.
A. takes place only during a particular season
B. occurs only during the night
C. is a daily practice
D. only happens when a species becomes over-populated
