　　VoIP stands for Voice over Internet Protocol．It is also referred to as IP Telephony．It is another way of making phone calls, though the “phone” part is not always present anymore, as you can communicate without a telephone set．VoIP is especially popular with long distance calls．The main reason for which people are so massively turning to this new technology is the cost．VoIP is said to be cheap, but most people use it for free．Yes, if you have a computer with a microphone and speakers, and a good Internet connection, you can communicate using VoIP for free．

　　The growth of VoIP today can be compared to that of the Internet in the early 90's．The public is getting more and more conscious of the advantages they can get from VoIP at home or in their businesses．Advertising campaigns, which are present everywhere on the net, are contributing a lot towards the popularization of VoIP which is not only giving facilities and allowing people to save, but also bringing in huge income for those who dived early into the new phenomenon．

　　In the United States, boys and girls start school when they are five years old. In some states they must stay in school until they are sixteen. Most students are seventeen or eighteen years old when they graduate from secondary school. Another name for secondary school is high school.

　　Most children go to public elementary (初小) and secondary school.

A student at a state university does not have to pay very much if his parents live in that state. Private colleges and universities are expensive.

阅读理解：

　　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)

The author uses the example of the robot in space exploration to tell us ________．
[　　]
A．	the differences between robots and men
B．	the reason why men need to sleep
C．	about the need for robots to save power
D．	about the danger of men working at night

(2)

Evolution has programmed man to sleep at night chiefly to help him ________．
[　　]
A．	keep up a regular pattern of life
B．	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)

Cats sleep much more than horses do partly because cats ________．
[　　]
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)

Which of the following is the main idea of the passage?
[　　]
A．	Evolution has equipped all creatures with a regular pattern of sleeping and waking．
B．	The study of sleep is an important part of the evolutionary theory．
C．	Sleeping patterns must be taken into consideration in the designing of robots．
D．	The sleeping pattern of a living creature is determined by the food it eats．

　　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．

(1)

What they could see in the boat was only ________．
[　　]
A．	high wall

[　　]
A．	the mud on the shore was too soft
B．	the forest was too thick to let them go through
C．	they could not find the mark on the map
D．	they could not find anyone to lead them out of the forest．

(3)

The passage infers that the forest was ________．
[　　]
A．	rich of fruits and animals to be served as food
B．	not very thick as they could advance slowly by cutting the branches
C．	full of various dangerous beings
D．	full of ancient trees

(4)

[　　]
A．	Escape
B．	Scenes of a River
