Many people believe the glare（炫目的光）from snow causes snowblindness. Yet, with dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness ,when exposed to several hours of“ snow light”.

　　The United States army has now determined that glare from snow does not cause snowblindness in troops in a snow -covered country. Rather ,a man’s eyes frequently find nothing to focus on （聚集） in a broad space of snow- covered without- grass land. So his gaze continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles ache. Nature makes up for this discomfort by producing more and more fluid （流 体） which covers the eyeball. The fluid covers the eyeball in increasing quantity until it makes eyes difficult to see dearly, and the result is total, even though for a short time, snowblindness.

　　Experiments led the Army to a simple method of overcoming this problem. Scouts（侦察兵）ahead of the troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow - covered landscape. Even the scouts themselves throw lightweight, dark - colored objects ahead on which they can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snow -blanketed landscape. By focusing their attention on one object at a time. the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a continuous white land is overcome.

To prevent snowblindness caused by the strong light from snow, wearing glasses or not ________.

　　A. depends on whether the snow is white enough

　　B. makes no difference

　　C. makes much difference

　　D. depends on whether the snow is thick

When the eyes are tired, tears flow out ________.

　　A. to clear the vision

　　B. to make the eyes stop searching

　　C. to make the vision unclear

　　D. to produce more and more liquid

Snowblindness can be avoided ________.

　　A. by moving one’s gaze back and forth

　　B. by walking ahead and keeping looking around

　　C. by making up for the discomfort of one’s eyes

　　D. by providing the eyes with something to focus on

　　It was Monday. Mrs Smith's dog was hungry, but there was not any meat in the house.
　　Considering that there was no better way, Mrs Smith took a piece of paper, and wrote the following words on it:“Give my dog half a pound of meat.”Then she gave the paper to her dog and said gently:“Take this to the butcher(*person whose job is selling meat). and he's going to give you your lunch today.”
　　Holding the piece of paper in its mouth, the dog ran to the butcher's. It gave the paper to the butcher. The butcher read it carefully, recognized that it was really the lady's handwriting and soon did it as he was asked to. The dog was very happy, and ate the meat up at once.

　　The next day, the dog came again exactly at noon. And as usual, it brought a piece of paper in the mouth. This time, the butcher did not take a look at paper, and gave the dog its meat, for he had regarded the dog as one of his customers (*people who buy sth. from a shop).
　　But, the dog came again at four o'clock. And the same thing happened once again. To the butcher's more surprise, it came for the third time at six o'clock, and brought with it a third piece of paper. The butcher felt a bit puzzled. He said to himself, “This is a small dog.

　　根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
　　The purpose of a letter of application is to help you to "sell" yourself. 71 It should be simple,human,personal and brief without leaving out any necessary facts.
　　In writing a letter of application,keep in mind that the things a possible employer is most likely to want to know about are your qualifications(条件),your achievements and your aims. 72 If the first few sentences fail to win the reader's attention,the rest of the letter may not be read at all.Try to focus your opening remarks on the needs or interests of the employer not on your own need or desires.For example,instead of beginning with "I saw your advertisement in today's newspaper,"you might say " 73 "or "I have made a survey in my neighborhood to find out how many housewives use your product and why they like it."
　　 74 Be clear about the kind of job for which you are now aplying.College graduates looking for their first positions often ask "Which can I provide in a letter? Employers want experience - which,naturally,no beginner has." The answer is that everything you have ever done is experience.
　　It is important to write a good strong closing for your letter.Make a specific request for an interview or give the possible employer something definite to do or expect.At excellent idea is to enclose(内附)a stamped,self - addressed envelope with your letter. 75
