　　Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.

　　The scientists say that the human body has changed very little since human first appeared on the earth,but the way we live has changed greatly. Our body has not been able to deal with these changes in life style (方式) and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times (古代). So they are called “diseases of civilization”. Many cancers and diseases of the blood system (系统),including heart attacks and stroke (中风) are examples of such diseases.

　　Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol (酒精) or tobacco (烟草),probably none. Ancient people also got a great deal of physical exercise,but a change in food is one of the main differences between life in ancient times and that of today.

　　Stone-age people hunted wild animals for their meat,which had much less fat than domestic or tame ones (家畜). They also ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products,and they made very little use of grains. But today,we eat a large amount of these. We eat six times more salt than our remote ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein (蛋白质) and much less vitamin. (维生素) C．

　　People today probably do not want to live the way people thousands of years ago did,but scientists say that we would be much healthier if we ate much the same way our remote ancestors did,cutting the amount of fatty,salty and sweet food．

(1)According to the passage,people in industrialized nations would be much healthier if they eat _________.

(2)New kinds of sicknesses have been found because________.

[　　]

A．the human body has changed compared with(同……比较) human first appeared on the earth

B．the way we live has changed a little

C．our body can't deal with the changes in life style

D．the way we live today is proper for the human body

[　　]

A．Ancient people did a great deal of physical exercise

B．People today have a lot of alcohol

C．People today have more tobacco

　　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

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．

　　One day I bought a house．One day－what a day!–I became a father, and not too long after that I picked up the check for my own father．I thought then it was a milestone for me．One day, when I was a little older, I realized it was one for him, too, another milestone．
