Karen, grown up in a very traditional family in the western United States, maintained high moral(道德的)standars throughout her youth．．In 1984, at the age of 23, she married Bill．They were blessed with two children, a boy and a girl．
By 1991 their love had deepened, and they were happy．Later that year, Bill developed a white spot on his tongue．He visited a doctor．
One day shortly after that, Bill called Karen to sit beside him．He said with tears in his eyes that he loved her and wanted to live forever with her．The doctor suspected that he had been infected with HIV, the virus that leads to AIDS．
The family was tested．Bill and Karen’s results were positive．Bill had become infected before he met Katen;then he passed the virns on to Karen．The children’s results were negative．Within three years, Bill was dead．“I don’t know how to express what it is like to watch the once handsome man you love and intend to live with forever dying slowly．I cried many nights．He died three months short of ten years of our marriage, ”says Karen．Though a doctor told Karen that she would soon follow her husband into death, she is still alive．The infection has progressed to the early stages of AIDS．
Karen is but one of about 30 million people now living with HIV/AIDS, a figure larger than the combined populations of Australia．Ireland and Paraguay．According to one UN report, Africa has 21 million of these victims．By the turn of the century that number could reach 40 million and the disease will bring on the greatest disaster in human history．Of the wold’s sexually active adults aged 15 to 49, 1 in 100 has already been infected with HIV．Of these, only 1 in 10 realizes that he or she is infected．In some parts of Africa, 25 percent of the adults are infected．
Since the beginning of the spread of AIDS in 1981, about 11.7 million people have died of it．It is roughly calculated that in 1997 alone, about 2, 3 million people died of it．Nevertheless, there are fresh reasons for optimism in the battle against AIDS．During the past few years, there has been a drop in new AIDS cases in wealthy nations．In addition, promising drugs hold out hope of better health and longer life．

It can be concluded from the passage that________．
Suppose we built a robot(机器人)to explore the planet Mars．We provide the robot with seeing detectors(探测器)to keep it away from danger．It is powered entirely by the sun．Should we program the robot to be equally active at all times?No．The robot would be using up energy at a time when it was not receiving any．So we would probably program it to stop its activity at night and to wake up at dawn the next morning．
According to the evolutionary(进化的)theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason．The theory does not deny(否认)that sleep provides some important restorative functions(恢复功能)．It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous．However, sleep protects us only from the sort of trouble we might walk into; it does not protect us from trouble that comes looking for us．So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent．
The evolutionary theory explains the differences in sleep among creatures．Why do eats, for instance, sleep so much, while horses sleep so little?Surely cats do not need five times as much repair and restoration as horses do．But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep．Horses must spend almost all their waking hours eating, because what they eat is very low in energy value．Moreover, they cannot afford to sleep too long or too deeply, because their survival(生存)depends on their ability to run away from attackers．
(1)

[ ]
A．
the differences between robots and men

prevent trouble that comes looking for him
C．
avoid danger and inefficient labour
D．
restore his bodily functions
(3)
According to the author, we cannot sleep well when we ________．
[ ]
A．
are worrying about our safety
B．
are overworked
C．
are in a tent
D．
are away from home
(4)

[ ]
A．
need more time for restoration
B．
are unlikely to be attackers
C．
axe more active than homes when they are awake
D．
spend less time eating to get enough energy
(5)

Our boat floated on, between walls of forest too thick to allow us a view of the land we were passing through, though we knew from the map that our river must from time to time be passing through chains of hills which crossed the jungle plains．Nowhere did we find a place where we could have landed：where the jungle did not actually spread right down into the river, banks of soft mud prevented us going ashore．In any case, what would we have sailed by landing?The country was full of snakes and other dangerous creatures, and the jungle was so thick that one would be able to advance only slowly, cutting one’s way with knives the whole way．So we stayed in the boat, hoping we reached the sea, a friendly fisherman would pick us up and take us to civilization．
We lived on fish, caught with home-made net of string(we had no hooks), and fruits and nuts we could pick up out of the water．As we had no fire, we had to eat everything, including the fish, raw I had never tasted raw fish before, and I must say I did not much enjoy the experience; perhaps sea fish which do not live in the mud are less tasteless．After eating my raw fish, I lay back and dreamed of such things as fried chicken and rice, and ice-cream．In the never-ending damp heat of the jungle, ice-cream was a particularly frequent dream．
As for water, there was a choice：we could drink the muddy river water, or die of thirst．We drank the water．Men who had just escaped what had appeared to be certain death lose all worries about such small things as diseases caused by dirty water．In fact, none of us suffered from any illness as a result．
One day we passed another village, but fortunately nobody saw us．We did not wish to risk being taken prisoners a second time：we might not be so lucky to escape in a stolen boat again．

The girls in this sixth grade class in East Palo Alto, California, all have the same access to computers as boys．But researchers say, by the time they get to high school, they are victims(受害者)of what the researchers call a major new gender(性别)gap in technology．Janice Weinman of the American Association of University Women(AAUW)says,“Girls tend to be less comfortable than boys with the computer．They use it more for word processing rather than for problem solving, rather than to discover new ways in which to understand information．
After re-examining a thousand studies, the AAUW researchers found that girls make up only a small percentage of students in computer science classes．Girls rate themselves significantly lower than boys in their ability and confidence in using computers．And they use computers less often than boys outside the classroom．
An instructor of a computer lab says he's already noticed some difference．Charles Cheadle of Cesar Chavez School says,“Boys are not so afraid they might do something that will harm the computer, whereas girls are afraid they might break it somehow．”
Six years ago, the software company Purple Moon noticed that girls' computer usage was falling behind boys．Karen Gould with the company says,“The number one reason girls told us they don't like computer games is not that they're too violent, or too competitive．Girls just said they're unbelievably boring．”What girls want, Purple Moon found, is characters they can relate to and story lines relative to what's going on in their own lives．“What we definitely found from girls is(that there is no intrinsic)(内在的)reason why they wouldn't want to play on a computer; it was just a content thing,”says Karen Gould．
The sponsor of the study says it all boils down to this：the technology gender gap that separates the girls from the boys must be closed if women are to compete effectively with men in the 21st century．
