　　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．

Suppose we built a robot 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 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 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 explain the 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.

A new study in West Africa shows how farm irrigationsystems powered by the sun can pro-duce more food and money for villagers． The study-in Benin found that solar - powered pumpsare effective in 8upplying water, especially during the long dry season．
Sub - Saharan Africa is the part of the world with the least food security． The United Na-tions Food and Agriculture Organization estimates that more"than one biillion of the world' s peo-ple faced hunger last year．Around 265 million of them live'south of the Sahara Desert: Lack of rainfallis one oftheir main causes offood shortages．．
Jennifer Bumey from Stanford University in Califomia led the study．The research team helped build three solar - powered drip irrigation -（滴灌） ,systems in northem Benin． Between 30 and 35 women used each system to pump water from the ground or a stream．Each woman was responsible for farming her own 120 sqrurre meters of land． They also farmed other land collectively．
The solar - powered irrigation systems produced an average of nearly two tons of vegetables per montb． During the first year, the women．kept a monthly average of almost rune kilograms of vegetables for home use．They sold the surplus produce at local markets． The eamings greatly increased their ability to buy food during the dry season which can last six to nine months． Peo- ple in the'two villages with the systems were able to eat three to five more servingsof yegetables per day．But making the surplus available at markets also had a wider effect．
The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets． The amount of vegetables eaten in those villages also increased, though not as much．The researchers note that only four percent of the croplamd in sub - Saharan Africa is irrigated． Using solar power to pump water has higher costs at first． But    the study says it can be more economical in the long term than using fuels like gasoline, diesel or kerosene． And solar power is environmentally friendly．
66．Food security in Sub - Saharan Africa is insufficient mainly because of
A．lack of rainfall         B．limitation of farmland
C． a small crop variety   D．little sunlight
67．From the third paragraph we know that _______．
A．water is wasted by using the system
B． the farmers imgate the land together
C． all farmers use irrigation systems in northem Benin
D． the solar - powered systems take up more manpower
68．The underlined word "surplus" in the 4th paragraph most probably means_______
A．special             B．unnecessary      C．extra      D．abandoned
69．Usinf．solar power to pump water has advantages EXCEPT that
A．solar energy has higher cost at first
B．solar power helps to protect environment
C．solar power helps farmers increase eanungs
D． solar energy can be more economical in the long run
70．What can be the best title for the text?
A．Manpower affects rainfallin Africa
B．Irrigation by carrying water in buckets
C．Solar - powered pumps aid African farmers
D．Vegetable supply increased in African villages

A long time ago, there was a seed and because he was only a seed, nobody noticed him. Thus, feeling inferior (低级的), the seed gave no importance to his existence (存在). Then one day, a wind picked him up and threw him on an open field in the sun. Later, he was given rain. Years later he saw a traveler sitting by his side. "Thank you God for this. I really need some rest," he heard the traveler say. "What are you talking about?" the seed quickly asked. He thought the man was making fun of him. No one ever spoke to him like that. "Who just spoke?" the shocked man asked. "It is me. A seed." "A seed?" The man looked at the big tree. "Are you joking? You are not a seed. You are a big tree!" "Really?" "Yes! Why else do you think people come here?" "What do they come here for?" "To feel your shade (树阴)! Don’t tell me you didn’t know you had grown over time." A moment passed before the traveler’s words brought him pride. The seed thought and smiled for the first time in his life. The years of torture (折磨) by the sun and the rain finally helped him grow up. "Oh! That means I’m not a little seed anymore! I was actually born to make people feel comfortable. Wow! That’s great!"

阅读下面短文并回答问题，然后将答案写在横线上（请注意问题后的词数要求）

[1] A green house is a building made of glass which is used to keep warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surrounds the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as “greenhouse gases”, and the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.

[2] The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increasing in greenhouse gases is making the world warmer. The world’s temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimeters. If the amount of carbon dioxide(二氧化碳) in the atmosphere doubles, there will probably be a rise in the earth’s temperature of between 1 and 4℃. This____________________, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.
