《综合英语》考试试卷（A卷、闭卷）Part I Reading Comprehension (阅读理解) （每小题3分，共15分）Passage OneSuppose we built a robot to explore the planet Mars. We provide the robot with seeing detectors 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 cease its activity at night and to wake up at dawn the next morning.According to the evolutionary theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason. The theory does not deny that sleep provides some important restorative functions. 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 accounts well for differences in sleep among creatures. Why do cats, 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 depends on their ability to run away from attackers.1.The author uses the example of the robot in space explorationto tell us .A) the differences between robots and menB) the reason why men need to sleepC) about the need for robots to save powerD) about the danger of men working at night2.Evolution has programmed man to sleep at night chiefly to helphim _______.A) maintain a regular pattern of lifeB) prevent trouble that comes looking for himC) avoid danger and inefficient laborD) restore his bodily functions3. According to the author, we cannot sleep well when we ______.A) are worrying about our safety B) are overworkedC) are in a tent D) are away from home4. Cats sleep much more than horses do partly because cats ______.A)need more time for restorationB) are unlikely to be attackersC) are more active than horses when they are awakeD) spend less time eating to get enough energy5.Which of the following is the main idea of the passage?.A) Evolution has equipped all creatures with a regular patternof sleeping and waking.B) The study of sleep is an important part of the evolutionarytheory.C) Sleeping patterns must be taken into consideration in thedesigning of robots.D) The sleeping pattern of a living creature is determined bythe food it eats.Part II Vocabulary & Structure 词汇和结构（每小题2分，共30分）1.The meeting’s been canceled.

For each blank there are four choices marked A), B), C) and D) on the right side of the paper. You should choose the ONE that best fits into the passage. Then mark the corresponding letter on the Answer Sheet with a single line through the center.A language is a signaling system which operates with symbolic vocal sounds (语声), and which is used by a group of people for the purpose of communication.Let’s look at this 1 in more detail because it is language, more than anything else, 2 distinguishes man from the rest of the 3 world. Other animals, it is true, communicate with one another by 4 of cries: for example, many birds utter 5 calls at the approach of danger; monkeys utter 6 cries, such as expressions of anger, fear and pleasure. 7 thesevarious means of communication differ in important ways 8 human language.For instance, animals’ cries do not 9 thoughts and feelings clearly. This means, basically, that they lack structure. They lack the kind of structure that 10 us to divide a human utterance into 11.We can change an utterance by 12 one word in it with 13: a good illustration of this is a soldier who can say, e.g., “tanks approaching from the north”, 14 who can change one word and say “aircraft approaching from the north” or “tanks approaching from the west”; but a bird has a single alarm cry, 15 means “danger!”This is why the number of 16 that an animal can make is very limited: the great tit (山雀) is a case 17 point; it has about twenty different calls, 18 in human language the number of possible utterances is 19 . It also explains why animal cries are very 20 in meaning.（）1. A) classification B) definitionC)function D)perception（）2. A) that B) it C)as D)what（）3. A)native B) human C) physical D) animal（）4.
