　　It has been discovered that the bamboo plants the giant pandas eat are dying. As a result, many of the pandas are dying of 4 . In the wild, the giant panda eats only two kinds of bamboo plants. One is the umbrella bamboo; 5 is the fountain bamboo. 6 kinds can live 100 years. In its 7 year the bamboo plant blooms, has seeds and dies.

　　Last year the umbrella and the fountain 8 9 grow in China became 100 years old. The plant grows from seeds formed in the late 1870's. Now almost all of these bamboo plants are dead. Young shoots now grow from the seeds. However, it will be many months before the shoots are large enough to be eaten as food by the pandas. So the large black and white animals continue 10 .

　　Can the wild pandas be 11 ? A group of American scientists went to China 12 the pandas in their native habitat. The studies took place in the. areas of Sichuan Province in south-west China.

Large areas of the giant pandas habitat have been set 17 as wildlife preserves 18 the pandas can live freely. At the same time, Chinese scientists are trying to increase 19 number of giant pandas 20 some of the animals in zoos. The first baby panda was born in Beijing Zoo in the autumn of 1978.

答案：C;A;B;A;D;B;B;C;A;B;A;C;B;B;C;C;A;A;A;B
解析：

(1) C 表示假设.本小题易误选D项，但是这句话讲的并不是一个事实，而是虚拟的假设，因此正确答案应为C项.

(2) A 人类并没有面临这类问题.本小题也易误选D项，这主要是由两方面的原因所致：一是读题不够认真，文中的Luckily本身就表明人类现在并不面临这一问题；二是没有注意到该句叙述的是一个一般事实，因此要用一般现在时态.

(3) B 名词前应被形容词修饰，而此题只有lovely为形容词，故选B.

(4) A 根据上下文.应为死于“饥饿”，C项hungry为形容词，故选名词hunger.

(5) D 表示“两个之中的另一个”，是one…the other结构.

(6) B 很明显是指上文提到的两种竹子.

(7) B 句意为：在第一百年的时候，竹子开花结果然后死亡.“第一百”应用序数词.

(8) C 指伞竹和喷泉竹.

(9) A 关系代词.本小题应该选A项，而不能选其他选项，因为这里需要一个关系代词作主语引导定语从句 (that grow in China).

(10) B 没有这两种竹子作为食物，熊猫继续死亡.本小题的误选是由于没有正确把握上文所提供的语料信息，----竹笋需要好几个月才能长大供熊猫吃，因此熊猫的食物自然是个问题，所以答案不可能是A项或C项.再则，熊猫的不断死亡这一情况属于动作，而不属于状态，因此D项亦应予以排除.

(11) A 用被动语态表示“被拯救”.

(12) C 这里用study表示“研究”大熊猫；搜寻大熊猫为search for the pandas，这里不属此句型，故A应排除.

(13) B 发现关于大熊猫食物的更多的情况.

(14) B if在这里表示“是否”之意.相当于whether,引导宾语从句.

(15) C 他们想看一下在这两种竹子正在生长的时候.大熊猫是否能够吃别的食物来代替.

(16) C “已经采取措施”，用现在完成时.选C项是因为take steps表示“采取措施”，其他选项均不能与steps搭配，构成动宾关系.

(17) A set aside表示“留下将来使用”之意.

(18) A 先行词表示地点，where引导一个限制性定语从句修饰先行词 wildlife preserves.

(19) A 句意为“提高大熊猫的数量”，故用定冠词the来修饰number.

(20) B 选by raising表示“通过……”.

阅读理解：

　　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．
