1、What Do Dreams Tell Us?Why do we dream? Do dreams have meanings? These are questions which have troubled man forthousands of years. The oldest surviving book on the interpretation of dreams is Egyptian and is nearly 4,000 years old. In ancient Greece, it was thought that people who were ill could be cured by telling their dreams. They would relate their dreams to their doctors who would tell them what they meant and then give them medicine to make them well. The ancient Chinese believed that if a pregnant woman dreamed of a bear, she would have a son, and if she dreamed of a snake, she would have a daughter. There are many stories about dreams foretelling (预言) the future.We certainly do not now believe that dreams foretell the future. Most scientists believe that dreams are based on events in our own life and on our feelings. The events are usually very recent, mostly within the last two days. Our emotions, on the other hand our wishes, hopes and fears may go back many years, even to early childhood.In a dream, events are altered. A dream may contain parts of many real-life events. Most importantly, something that cannot be shown directly may be shown indirectly. Forexample, you might dream of driving a large car. This could mean not that you want to have a larger car, but that you desire power, and maybe you want to control other people. Again, you may dream that you are an actorin a play. The play is about to start, but you have completely forgot your lines. This dream may seem strange because you are not interested in acting, and you never want to be in a play. But the dream may mean that you have some other problem that you feel is too difficult foryou to solve.Psychologists believe that dreams may be helpful to us. Indeed, people who have been allowed to sleep in experiments, but not allowed to dream, have become anxious and restless. and when they are later allowed to sleep as much as they like, they dream more than ever to make us forthe lost "dream time".

3、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron fora month. They found that 100 years later only between 2 and 13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer and better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same.______."【单选题】
A.Its opponents argue, however, that it will stop global warming.
B.Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.
C.As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.
D.They found that 100 years later only between 2 and 15 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.
E."These are newer and better models,"
F.Ocean fertilization is not the answer to global warming.
正确答案:F
答案解析:空白位置暗示该句句意的特点,往往是总结、概括句。对比剩下的选项A和F,选择F.考点:句子之间的逻辑发展。A根据all的习惯搭配:all+指示代词,因此首先排除B(人称代词)。结合前句内容,空白处的代词应该指代前句中提到的“敏锐的眼睛和耳朵、反应迅速的大脑、手和大脑之间的协调”,因此应该选择指代复数的指示代词these。
4、WaterThe second most important constituent (构成成份) of the biosphere (生物圈) is liquid water. This can only exist in a very narrow range of temperatures, since water freezes at 0℃ and boils at 100℃. Life as we know it would only be possible on the surface of a planet which had temperatures somewhere within this narrow range.The earth\'s supply of water probably remains fairly constant in quantity. The total quantity of water is not known very accurately, but it is about enough to cover the surface of the globe to a depth of about two and three - quarter kilometers. Most of it is in the form of the salt water of the oceans about 97 percent. The rest is fresh, but three -quarters of this is in the form of ice at the Poles and on mountains, and cannot be used by living systems until melted. Of the remaining fraction, which is somewhat less than one percent of the whole, there is 10 -20 times as much stored underground water as there is actually on the surface. There is also a tiny, but extremely important fraction of the water supply which is present as water vapour in the atmosphere.Water vapour in the atmosphere is the channel through which the whole water circulation (循环) of the biosphere has to pass. Water evaporated (蒸发) from the surface of the oceans, from lakes and rivers and from moist (潮湿的) earth is added to it. From it the water comes out again as rain orsnow, falling on either the sea orthe land. There is, as might be expected, a more intensive evaporation per unit area over the sea and oceans than over the land, but there is more rainfall over the land than over the oceans and the balance is restored by the runoff from the land in the form of rivers.The word "fraction" in the second paragraph means ______.【单选题】
A.a very small amount
B.a large area
C.an important system
D.a majorsource of information
正确答案:A
答案解析:本题难度不大,文章第二段第四句谈到剩余部分大约小于1%,可以判断fraction意思是指“很少一部分”,此外也可迅速查词典,确定答案,答案是A。
5、Can you give a concrete example to support your idea?【单选题】
A.specific
B.real
C.special
D.good
正确答案:A
答案解析:你可以举一个具体的例子来支持你的观点吗?本题有一定难度,concrete,常用词汇,指“具体的”,specific 一般指“特殊的”引申意思指“具体的”,这里和concrete,是同义词,special指“特殊的”,没有“具体的”意思,最佳答案是A。
