根据短文内容, 从下面A到F选项中选出能够概括每段主题的最佳选项, 选项中有一项为多余项

A. Tools of thought

B. A reflection of your personality

C. An indication of your intelligence

D. The explosive effect of words

E. A direction of the history

F. Change the direction of your life

(填涂说明:E=A+D   F=B+D   G=C+D )

The extent of your vocabulary indicates the degree of your intelligence. Your brain power will increase as you learn to know more words. Here's the proof. Two classes in a high school were selected for an experiment. Their ages and their environment were the same. Each class represented an identical cross-section of the community. One, the control class, took the normal courses. The other class was given special vocabulary training. At the end of the period the marks of the latter class surpassed those of the control group, not only in English, but in every subject, including mathematics and the sciences. Similarly it has been found by Professor Lewis M.Terman, of Stanford University, that a vocabulary test is as accurate a measure of intelligence as any three units of the standard and accepted Stanford-Binet I.Q. tests.

The study of words is not merely something that has to do with literature. Words are your tools of thought. You can't even think at all without them. Try it. If you are planning to go down town this afternoon you will find that you are saying to yourself: "I think I will go down town this afternoon." You can't make such a simple decision as this without using words. Your words are your keys for your thoughts. And the more words you have at your command the deeper, clearer and more accurate will be your thinking.

A command of English will not only improve the processes of your mind. It will give you assurance; build your self-confidence; lend color to your personality; increase your popularity. Your words are your personality. Your vocabulary is you. Your words are all that we, your friends, have to know and judge you by. You have no other medium for telling us your thoughts-for convincing us, persuading us, giving us orders.

Words are explosive. Phrases are packed with TNT.A simple word can destroy a friendship. The proper phrases in the mouths of clerks have quadrupled the sales of a department store. The wrong words used by a campaign orator have lost an election. For instance, on one occasion the four unfortunate words, "Rum, Romanism and a Rebellion" used in a Republican campaign speech threw the Catholic vote and the presidential victory to Grover Cleveland. Ears are won by words. Soldiers fight for a phrase. "Make the world safe for Democracy." "All out for England." "V for Victory." The " Remember the Maine" of Spanish war days has now been changed to "Remember Pearl Harbor."

Words have changed the direction of history. Words can also change the direction of your life. They have often raised a man from mediocrity to success. If you consciously increase your vocabulary you will unconsciously raise yourself to a more important station in life, and the new and higher position you have won will, in turn, give you a better opportunity for further enriching your vocabulary. It is a beautiful and successful cycle.

Today’s opportunity erase yesterday’s failures.

Cloud seeding is a method of artificially causing clouds to produce precipitation (降水) in the form of rain or snowCloud seeding has also been used in attempts to modify the severity of hail storms and hurricanesThe effectiveness of cloud seeding remains controversial (有争议的).but it continues to be used in some regions to try to increase rainfall for agriculture and to build snow packs for water supplies and power production

Cloud seeding was developed by American scientists Irving Langmuir and Vincent Joseph Schaefer during and after World War IITheir work began as an effort to learn more about the buildup of ice on airplane wings, and eventually led them to attempt to create rainfall by releasing several pounds of crushed frozen carbon dioxide into a cloud from an airplaneIn this form, the carbon dioxide is called dry iceOn November 13, 1946, the technique appeared to produce snow directly under the cloud; the snow then turned to rain as it fell to the ground

For their experiment, Langmuir and Schaefer selected a supercooled cloud, one in which the water droplets remain liquid in subfreezing temperaturesTheir theory was that small grains of dry ice falling through the cloud would cause tiny droplets of water vapor in the cloud to freeze into crystals that attracted more water vaporTheir theory proved to be correct and eventually the crystals became heavy enough to fall from the cloud as snowAs the snow reached the warmer temperatures closer to the ground, it melted and became rain

Another scientist, Bernard Vonnegut, produced a method of cloud seeding using silver iodide (碘化银).He used particles of silver iodide because its crystal structure resembled that of ice in cloudsSilver

iodide also had practical advantages over frozen carbon dioxide It could be stored at room temperature

and did not require an airplane as a delivery mechanismInstead, silver iodide crystals could be fired by

cannons (大炮) high into the air, where wind carried them into the clouds

1.According to the text, Langmuir and Schaefer had intended to deal with__

Christmas bird – watching is popular in the U.S.A. When the holiday season comes, some Americans are likely to watch and count birds in the sky with great interest every day. This activity began in the early part of the last century. It has a one-hundred-year history. At that time, there was a so-called “holiday hunting” custom. In order to celebrate the holiday, the hunters went out to kill birds and beasts. By 1900, there were 27 bird lovers who decided to count birds instead of killing birds. Since then, Christmas bird-watching was held every year. It has been continued to the present.

There were 42000 people who took part in the bird-watching last Christmas, from December 16 the year before to January 3 next year. They were in the United States and Canada, central America, south America and the Caribbean, watching and counting birds in the sky. The whole viewing area was divided into 1600 points. Each birdwatcher was responsible for 25 meters, and was required to write down the types and quantities of birds within 24 hours.

A birdwatcher described what he had watched vividly in his diary—“ When I looked up, I saw a beautiful ‘landscape’ in the sky: Red-crowned cranes(丹顶鹤) were driving up in cunning wedges that split the air. They were so neatly arranged, coordinating their movements. I was excited and breathtaking. Interestingly, the “human” shape(人字行) always maintains 110° ” .

“Why do red-crowned cranes choose to use ‘human’ shape when flying in formation?” He continued, “In my opinion, there are four reasons: first, the ‘human’ shape can make red-crowned cranes use increasing air which is produced by each other’s wings when they are swinging in the sky. It can increase the glide time and save physical ability. Second, the ‘human’ shape will enhance communication among the birds. The orders and the relevant information issued by the lead bird can be conveyed to each member in this migratory group unimpeded, accurately, rapidly and conveniently. Third, such a formation will help to find the birds left behind because of feeling run down as fast as possible, so that the young, the weak, the sick birds can get everyone’s help and encouragement. Finally, the ‘human’ shape shows not only beauty but also unity. It can give enemies a deterrent.They will be terrified and did not dare to attack the birds.The migration security of the birds will be ensured.”  

Environmental experts admired and evaluated Christmas bird-watching highly. They pointed out that it made perfect sense. On the one hand it could enhance the human awareness of environmental protection. On the other hand it could provide first-hand information on birds.

49.When did Christmas bird – watching begin?

         A.Sometime during Christmas holiday.         B.At the beginning of 20th century.

         C.In the early 19 th century.          D.Since there was Christmas Day

         A.They kill birds and beasts.          B.They watch birds and beasts.

         C.They watch and count birds.     D.They look at the sky and write diaries.

51.The following are all reasons for red – crowned cranes flying in “human” shape except      .

         A.they can help each other and ensure their safety

         B.they can communicate with each other in order to reduce tiredness.

         C.they can make use of the air produced by each other’s wings.

         D.they can look stronger in case they come across enemies
