How Animals Keep Warm

Man has invented ways to keep warm,but how do animals defend themselves?They
cannot reason in the sense that man can,but nature has taken care of the animal kingdom
by providing animals with special instincts（本能）.One of these instincts is known as
hibernation（冬眠）.
" Sleeping like a dormouse（棒睡鼠）"is not only a common saying but is a reality.
When winter comes,the dormouse and other hibernating animals have reached a well-
nourished state.They eat very well in warmer days laying down fat in the tissues of their
bodies and during hibernation this keeps them alive.Safe in their nests,or burrows（地
洞）,they sleep soundly until the warmth of spring arrives.
Bats,tortoises,snakes,frogs,even insects like butterflies,hibernate more or less
completely. Some, like the squirrels（松鼠）,sleep during coldest weather but are roused
（弄醒）by a warm spell（暖流）.During hibernation, the temperature of an animal's body
drops drastically.Breathing and heart-beats almost cease.
Another instinctive method of avoiding intense cold is to escape by means of migration.
Wild swans,seagulls,swallows and cuckoos are a few of the very many kinds of birds
which fly thousands of miles,twice a year,to avoid cold.Many animals,especially those
of the Arctic regions,have summer and winter quarters.The Arctic deer of North America,
as well as the reindeer（驯鹿）of Europe,move southward towards the forests when winter
approaches.They return to the northern area when the warmth of spring begins to be
sensed.
There are animals which do not attempt to leave at the first sign of winter cold.Their
instinctive means of defense is to dig out a deep burrow,made it soft and warm by padding
（填塞）out with straw,leaves,moss and fur. In it they have a"secret place"containing
food which they hope will last the winter through!Animals which fall into this class include
the Arctic fox,the rabbit and the little field-mouse.

"Sleeping like a dormouse"most probably means
A:sleeping longer on cold days.
B:sleeping badly.
C:sleeping with a lower heartbeat rate.
D:sleeping with little breathing,

C:It lives on rabbits or field mice.
D:It stays in its burrow and lives on the food stored there.

Very few of our birds stay with us the year round.Some come to us in the winter from the cold?north.Others come from the south to spend the summer with us.How do they know the way?Suppose?you were told to find your way to a place hundreds of miles away,do you think you could do it?
Yet birds travel over mountains,forests,lakes and even across the oceans,and do not stray from?the path.They find their way back in the spring to the same orchard（果园）and the very trees where?they nested the summer before.
It is wonderful how quickly birds travel such long distances from their summer homes to their?winter ones.Some birds have been known to fly hundreds of miles in a day.But others travel much?more slowly.
Why do birds undertake these long journeys twice a year?Perhaps cold weather and lack of?food drive them from us in the autumn,but we cannot tell why they leave the sunny south to come?back to us in the spring.We know only that many of them like to make their nests and rear their?young in the north.
We are sorry to see them go,but we know that when winter is over they will come back to us.

The underlined part"stray from the path"means__________.

A.lose its way
B.stay on the path
C.keep away from the path
D.fly along the path
