Many people believe the glare from snow causes snowblindness. Yet, 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. A man's eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain(地域). So his long look continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and eyeballs become sore and the eye muscles ache. Nature offers this discomfort by producing more and more liquid which covers the eyeball. The liquid covers the eyeball in increasing quantity until vision became not clear, and then is not easily seen and the result is total, even though not very long, snowblindness.
Experiments led the Army to a simple method of solving this problem. Scouts, ahead of a main body of 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 too can focus. The men following can then see something. Their eyes focus on a bush and have something to see. 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 solid white terrain is solved.

C. By asking the Army for help.
D. By walking backwards.
4. A suitable title for this passage would be ________.

When you walk along a street in a big city in the United States， you may see clocks in most stores. Radio announcers give the correct time during the day. People there think that it is important to know the time. Most Americans have watches. They want to do certain things at certain times. They do not want to be late. Not all people all over the world value time. Suppose you visit a certain country in South America. You would find that people living there do not like to rush. If you had an appointment（约会）with someone， he would probably be late. He would not care for arriving on time. In some countries in South America， even the radio programs may not begin right on time， nor do the radio announcers think it important to announce the right time. Many people regard a clock as a machine. It seems to them that a person who does everything on time is controlled（控制）by a machine. They do not want a clock or any machine to have that much power over their lives.

5.The passage is most probably taken from_____.

Winter is dangerous because it’s so difficult to know what is going to happen and accidents take place so easily. Fog can be waiting to meet you over the top of a hill. Ice might be hiding under the melting (融化) snow, waiting ahead to send you off the road. The car coming to you may suddenly slip（滑） across the road.
Rule No.1 for driving on icy roads is to drive smoothly (平稳地). Sudden movements can make a car very difficult to control. So every time you either start or stop your car, increase or reduce your speed, you must be as gentle and slow as possible. Suppose you are driving with a full cup of hot coffee on the seat next to you. Drive so that you wouldn’t spill (溅) it.
Rule No.2 is to pay attention to what might happen. The more ice there is, the further down the road you have to look. Test how long it takes to gently stop your car. Remember that you may be driving more quickly than you think. Generally, allow twice of your usual stopping distance when the road is wet, three times this distance on snow than usual, and even more on ice. Try to stay in control of your car at all time and you will not get into trouble.

Did you enjoy yourself yesterday? I suppose you do. But I’d like to tell you what a bad day I had yesterday. Everything just went wrongly. On the morning, my alarm clock didn’t ring, since I woke up an hour late. I was in such a hurry that I burnt my hand when I was cooking the breakfast. Then I ran out of the house to catch the 8:30 buses. This is the bus I usually take. But, you may laugh, I missed it of course. I am very unhappy, and scared as well because teacher hates the students coming late to school. So I ran three miles to school only to found that nobody was there. The school was quiet but peaceful. Our classroom was locked. I realized that moment: It was Sunday.
