Only special plants can survive the terrible climate of a desert， for these are regions where the annual range of the soil temperature can be over 75℃. Furthermore， during the summer there are few clouds in the sky to protect plants from the sun's ray. Another problem is the fact that there are frequently strong winds which drive small， sharp particles of sand into the plants， tearing and damaging them. The most difficult problem for all forms of plant life， however， is the fact that the entire annualrainfall ours during a few days or weeks in spring.Grasses and flowers in desert survive from one year to the next by existing through the long， hot， dry season in the form of seeds. These seeds remain inactive unless the right amount of rain falls. If no rain falls， or if insufficient rain falls， they wait until the next year，or even still the next. Another factor that helps these plants to survive is the fact that their life cycles are short. By the time that the water from the spring rains disappears —— just a few weeks after it falls —— such plants no longer need any.The perennials have special features which enable them to survive as plants for several years. Thus， nearly alldesert perennials have extensive root systems below ground and a small shoot system above ground. The large root work enables the plant to absorb as much water as possible in a short time. The small shoot system， on the other hand，considerably limits water loss by evaporation.Another feature of many desert perennials is that after the rainy season they lose their leaves in preparation for the long， dry season， just as trees in wetter climates lose theirs in preparation for the winter. This reduces their water loss by evaporation during the dry season. Then， in next rainy season， they e fully alive once more， and grow new branches， leaves and flowers， just as the grasses and flowers in desert do.16. Ordinary plants are unable to survive in the desert mainly because of the changeable weather.A. RightB. WrongC. Not mentioned17. Grasses and flowers in desert are able to survive because they stay in the form of seeds to wait for theright amount of water to e.A. RightB. WrongC. Not mentioned18.

RightB. WrongC. Not mentioned21. The theme of the second last paragraph is why the perennials can survive as plants for several years.A. RightB. WrongC. Not mentioned22. Desert perennials lose their leaves after the rainy season just as trees lose theirs in wetter climates before winter arrives， but the reasons for this feature are different.A. RightB. WrongC.

You can do certain things in space (like floating around, or pushing huge objects) that you cannot do on earth. But being in space can do things to you, too. If you stay too long in a gravity-free environment, your bones could bee weak, and a small spaceship just might annoy you after a while, because space travel could make you seasick!On July 4, 1982, after seven days orbiting the earth, astronauts Thomas K. Mattingly and Henry W. Hartsfield returned home. Although not all of the experiments on boardworked properly, the flight basically seemed to be a suess except for one "little" thing: early in the flight, astronaut Hartsfield became "seasick".Thomas Mattingly, who is also a jet pilot and is highly resistant to motion sickness on earth, did much better. Mattingly sailed through space with a steady stomach. But no one knows why Hartsfield felt uneasy and Mattingly did not.So far it seems there is no reliable way to predict who will bee motion sick in outer space and who will not. in all, at least four astronauts have suffered from space motion sickness. Russian and American scientists are working together to try to understand and solve the motion sickness. Space program officials worry that if so many highly-trained pilots get sick in space, what will happen when civilians start flying in the shuttle?Motion sickness is a disagreeable feeling that es from the pitching, rolling, swaying, or just the moving of the object you are riding in or on. Symptoms of motion sickness include: dizziness, headache, a sinking feeling in the stomach, and vomiting.Why does motion make some people ill?Doctors believe that motion sickness is caused by a disturbance in the inner ear. Our ears do more than give us hearing. A part of the ears gives us a sense of balance andhelps make us aware of whether we are right side up or upside down.If you know that you get carsick or seasick, what can you do?Speak to your doctor. There are certain medicines available that can help stop that uneasy feeling. But many of them can also make you sleepy. Usually they work best taken before you begin feeling ill.Some people also remend water, ice cubes, mints, or plain toast. But these remedies do not always work for everyone.Perhaps, since motion sickness is such a big problem in outer space, researchers may soon find a way to cure the astronauts - and those of us who stay on earth.16 Floating in space for too long a time may also do harm to one's lungs and heart.A RightB WrongC Not mentioned17 At the end of the flight, Hartsfield became "seasick".A RightB WrongC Not mentioned18 Mattingly was much thinner than Hartsfield.A RightB WrongC Not mentioned19 Russian and American scientists are working together to solve the problem of motion sickness in astronauts.A RightB WrongC Not mentioned20 Untrained civilians are more likely to suffer from motion sickness in a spacecraftA RightB WrongC Not mentioned21 The motion sickness some astronauts suffered from during space travel had been caused by the defective digestive system.A RightB WrongC Not mentioned22 People suffering from motion sickness during space travel can alleviate its symptoms by eating or drinking something.A RightB WrongC Not mentioned参考答案：16.

CTornadoes(龙卷风)and heavy thunderstorms moved across the Great Lakes and into Trumbull County on Saturday evening.：The storms were dramatic and dangerous.George Snyder was driving the fire truck down Route 88 when he first noticed that a funnel(漏斗状的)cloud was behind him.“I stopped the truck and watched the funnel cloud.It was about 100 feet off the ground and I saw it go up and down for a while.It was moving toward Bradley Road and then suddenly it disappeared.”Snyder said.Snyder only saw one of the funnel clouds that passed through northeastern Ohio on Saturday.In Trumbull County, a tornado turned trees onto their sides.Some trees feel ontohouses and Cars.Other trees fell into telephone and electrical wires as they went down.Amanda Symcheck was having a party when the storm began.“I knew something was wrong，”she said.“I s aw the sky go green and pink(粉红色).Then it sounded like a train rushing toward the house.I started crying and told everyone to go to the basement for protection.”The tornado caused a lot of damage to cars and houses in the area.It will take a long time and much money to repair everything.There was also serious water damage from the thunderstorms.The heavy rains and high wind caused the power to go out in many homes.The storms caused serious flooding in areas near the river.More than four inches of rain fell in parts of Trumbull County.The river was so hight that the water ran into streets and houses.Many streets had to be closed to Cars and trucks because of the high water.'This made it difficult for fire trucks.police cars，and other rescue vehicles to help people who were in trouble.Many people who live near the river had to leave their homes for their own safety.Some people reported five feet of water in their homes.Local and state officials opened emergency shelters for the people who were evacuated(撤走).The Red Cross served meals to them.“This was a really intense storm。

重要句型（it句型）：It takes/took sb./sth. time/ money to do sth. 某人/某物花了时间/金钱做…It takes me an hour to go to school (上学) by bus（公共汽车）. 我乘公共汽车去学校要花一个小时的时间。

需要掌握的相关近义词词组：finish – accomplish – complete – fulfill 完成achieve是高频词汇，职称英语词汇选项练习部分出现了关于“achieve”的练习题：3. He achieved success（成功）through hard work（辛苦的工作）.A) reached（达到，伸出，范围）B) reaped（收割）C) attained（到达，获得）D) took （拿走, 占领, 接受）3．C．achieve的基本词义为“实现（目标），获得（成功）”，因此C（获得）是答案。
