　　Elephants don't forget—at least, female(雌性) elephants don't.

　　Elephant families are matriarchal . And the social knowledge gained by the oldest females is the key to the family group's survival (生存) , according to a study published in April by Karen MeComb, a biologist at Sussex University in England.

　　Elephants announce their presence by making a deep, long sound, a practice referred to as contact calling(联络呼叫) . An unfamiliar call may mean that the elephant from outside the family is nearby. A stranger can cause trouble, interrupting feeding or disturbing the young. So an elephant matriarch signals the family to gather around her: then they all lift their trunks in the sir to smell the unfamiliar caller. False alarms can disturb the group and take time and energy away from learning, so survival may depend in part on getting it right.

　　Working with Cynthia Moss, who founded the Amboseli Elephant Research Project in Kenya 30 years ago, McComb tested the social knowledge of 21 Amboseli elephant families with matriarchs 27 to 67 years old. She played recordings of contact calls to each family and found that the oldest matriarchs were much better at picking out unfamiliar calls. In fact, a group with a matriarch in her fifties was several hundred times more likely to form into a group upon hearing an unfamiliar contact call than when hearing a familiar call. However, families with younger matriarchs were less than twice as likely to gather together upon hearing an unfamiliar contact call as compared with a familiar call . And they gathered together a lot. Moreover, the social knowledge of older matriarchs translated into favorable results: Families with older matriarchs produced more baby elephants in each female reproductive year.

　　This finding shows how difficult it is to protect the oldest members of elephant families. As elephants age, they continue to grow larger, as do their much wanted tusks(象牙). So the older—and wiser—a Matriarch is, the greater the chance she will be killed. About 800, 000 elephants have been killed by people in the past 20 years.

4．The older a female elephant is , ________.

[　　]

　 As we know, Human beings each have unique brains. The brain is of the greatest importance to the body. It is the boss of the body．Your eyes，ears，nose，and skin tell your brain what is going on around you．Other parts of your body tell your brain what is going on inside of you．Your brain takes in the signals．It tells your body what to do with them．When you touch fire，your skin tells your brain that your finger is too hot．Your brain tells you to move your finger．All these happen very fast．Your brain also controls your breathing，blinking，and heartbeat．It controls your feelings and thoughts too．
　　Humans have the most developed brain of all animals．Yet it is not the largest brain．The human brain weighs three pounds．The brain of an elephant weighs 11 pounds．So the largest brain is not always the best brain．In people，a larger brain does not mean a clever person．
【小题1】What is the main idea of this passage?
　 

A．The human brain works very fast．

B．The largest brain is not always the best brain．

C．The brain controls the body．

D．The best brain is the largest brain．

【小题2】What happens after the brain takes in the signals from the body?

A．The brain grows faster and larger．	B．The brain tells the body what to do．
C．The body becomes more developed．	D．We don't know．

【小题3】What does “the boss of the body” mean?
