　　Before a new type of airplane goes into service, every part of it is tested again and again．But there are two tests that are more important than all the others．

　　The first is called the “tank test”．A modern airplane must fly very high in the sky．Air must be pumped into the plane so that the passengers can breathe．The metal structure(结构)of the plane has to be very strong for this reason．When the plane is filled with air, the air presses against the skin of the plane inside．The pressure(压力)on a small window is like a huge foot that is trying to get out．If a small part of the plane were to fail, the plane would explode^④ in the sky．To test the structure of the plane, the plane is lowered into a huge tank or container of water．Then it is filled with air．The pressure inside the plane is greater than it ever will be when it is high up in the air．Finally, there is an explosion．This does not cause so much damage inside the water tank as it would anywhere else．Engineers can discover which part of the plane has broken．Then that part is made stronger．

　　The most dangerous test happens when the new plane is going through test flights in the air．The test pilot must find out exactly what happens when the engines(发动机)are all shut off at once．The plane begins to fall like a stone．It is the pilot’s job to find out how he can get control of the plane again．These two tests are examples of how planes are made safe before they ever carry passengers．

(1)

By doing the “tank test”, the engineers can find out ________．
[　　]
A．	the amount of air in the plane
B．	the strength of the plane structure
C．	the pressure inside and outside the plane
D．	the power of the airplane engines

(2)

What will happen to the plane under the “tank test”?
[　　]
A．	It will be broken．
B．	It will be made stronger．
C．	It will be filled with water．
D．	It will be tested by pilots．

(3)

According to the text, why are test flights most dangerous?
[　　]
A．	The plane may explode in the air．
B．	The pilot may lose control of the plane．
C．	The engines may be damaged．
D．	Too much air may get into the plane．

(4)

What might be the most suitable title for the text?
[　　]
A．	Two Important Tests on Airplanes
B．	The Importance of Flying Safely
C．	The Danger of Testing Airplanes
D．	How Airplanes Are Made and Tested

答案：1．C;2．A;3．B;4．A;
解析：

(1)	细节推理题。根据文章第二段第八句，“tank test”的目的是“to test the structure of plane”。
(2)	细节推理题。根据第二段文意，首先可以排除C、D两项。从倒数第二句看到，工程师们在测验中会发现哪一部分会破，之后再进行加固。因此本题应选A项。
(3)	细节题。从第三段看出，进行测试时，飞机所有发动机同时关闭，飞机会像石头一样直接下降，飞行员要做的是怎样重新控制飞机。如此得出飞行测试时，飞机会失去控制，这是最危险的。
(4)	主旨题。这篇文章的主旨句出现在文章的首尾句。根据第一段“But there are two tests that are more important than all the others”和第三段末句“These two tests are examples of…carry passengers．”可得出答案。

　　In Europe, men do not usually wear skirts. But the Scottish national clothing for men is a kind of skirt. It is called a kilt. The Scottish like to be different. They are also proud of their country and its history, and they feel that the kilt is part of that history. That's why the men still wear kilts at traditional (传统的) dances and on national holidays. They believe they are wearing the same clothes that Scottish men always used to wear.

　　That's what they believe. However, kilts are not really so old. Before 1730, Scottish men wore a long shirt and blanket around their shoulders. These clothes got in the way when the men started to work in factories. So, in 1730 a factory owner changed the blanket into a skirt; the kilt. That's how the first kilt was made.

　　Then, in the late 1700s Scottish soldiers in the British Army began to wear kilts. One reason for this was national sentiment ( = feelings) . The Scottish soldiers wanted to be different from the English soldiers. The British Army probably had a different reason. A Scottish soldier in a kilt was always easy to find! The Scottish soldier fought very hard and became famous. The kilt was part of the fame, and in the early 1800s men all around Scotland began to wear kilts.

　　These kilts had colorful stripes (条纹) going up and down and across. In the 1700s and early 1800s, the color of the stripes had no special meaning. Men sometimes owned kilts in several different colors. But later the colors became important to the Scottish families. By about 1850, most families had special colors for their kilts. For example, men from the Campbell family had kilts with green, yellow and blue stripes. Scottish people often believe that the colors of the kilts are part of their family history. In fact, each family just chose the color they liked best.

　　This is not the story you will hear today if you are in Scotland. Most Scottish people still believe that kilts are as old as Scotland and that the colors are as old as the Scottish families. Sometimes feelings are stronger than facts!

1．This text is mainly about ________.

A．soldiers' clothes in Britain

B．the history of Scotland

C．a special kind of skirt

D．Scottish families

2．Which of the following is true according to the passage?

A．The English soldiers were the first to wear kilts.

B．It was hard then to tell the Scottish soldiers from the English ones apart from the clothes.

C．Colors were specially designed in the first kilts.

D．The factory owner made the first kilt from long shirts to make his workers different from others.

3．Scottish soldiers were dressed in kilts partly because of ________.

A．the colors

B．the weather

C．national sentiment

D．the design

4．The colors of the kilts are ________.

[　　]

A．not part of the Scottish family history

B．older than the Scottish family history

C．for the Campbell family only

D．mainly green, yellow and blue

5．From the last paragraph we can infer that ________.

[　　]

A．the European people are full of strong feelings

B．there are no stories about kilts in Scotland today

C．the British like to do things on feelings, not on facts

D．the Scottish prefer to keep their tradition rather than believe the fact

　　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. The parents of public school pupils do not have to pay directly (直接地) for their children's education because tax (税)money supports the public schools. If a child attends a private (私立) school, his parents pay the school for the child's education.

　　Today about half of the high school graduates go on to colleges and universities. Some colleges and universities receive tax money from the governments. 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. However, almost half of the colleges students in the United States work while they are studying. When a student's family isn't rich, he has to earn money for part of his college expenses.

　　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．

What they could see in the boat was only ________．
[　　]
A．	high wall
B．	villagers from time to time

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
