Do you know why different animals or insects have their special colors? Colors are used mainly to protect themselves.

Why can’t some birds easily catch locusts(蝗虫)? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as autumn comes, locusts change to the same brown color as crops have. Some other insects with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives in the day and appear only at night.

If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals can’t be easily seen by hunters. This is because they have the colors much like the trees.

Have you ever noticed an even more strange thing? A kind of fish in the sea can send out black liquid when it faces danger. While the liquid spreads over, its enemies can’t find it. And it quickly swims away. So it has lived up to now though it is not strong at all.

The Bermuda Triangle(百慕大三角)is in the Atlantic Ocean, near Florida in the USA. During the past 60 years, more than 1,000 seamen in ships and pilots in planes have lost their lives. It is known as “The Triangle of Death”for its strange seawater and sudden storms. What's the strangest is the light of the seawater, which looks so bright that it can be seen even from an outer spaceship.

  At 2:00p.m. on Dec. 5, 1945, five planes took off in fine weather from the airport of Florida, on a training task. Two hours later, the leader in the sky radioed that he was “completely lost”. Then there was silence. Another plane was sent to look for them and also disappeared.

  One of the largest ship that had disappeared in the triangle was an American coal ship, 500meters long. The weather was good, and there were no messages for help before it was “gone”. No broken ships or dead bodies have been found so far.

  No one is able to tell how all these accidents have happened. A group of Japanese scientists were there to see what it was really like in 1995, but nothing has been heard of them ever since.

2. How many planes had lost in December 1945?

  A. Five.     B. Six.     C. Seven.     D. Eight.

4. Why was the leader in the plane lost?

  B. He was losing the right direction.

Perhaps the only test score that I remember is the 55 when I was in high school.
The test was the final for a course. I remember waiting anxiously as my teacher Mr. Right passed out our papers one by one. It was a rather difficult test. I heard my classmates groaning, and I could tel by the groans that the scores weren’t looking good.
Mr. Right put my paper on my desk. There in big red numbers, circled to draw attention, was my score, 55!
I lowered my head, and covered the score up quickly. A 55 is not something that you wanted your classmates to see.“The scores were not very good, none of you passed,”Mr. Right said. “The highest score in the class was a 55.”
A 55. That’s me!
Suddenly my sad look didn’t look so bad. I had the highest score. I felt a lot better.
I walked home alone that day with the low but high score. My father knew that I had a big test that day and asked me as soon as I got home, “How did you do in your test?”“I made a 55,”I said.
A frown(皱眉)now stood on my father’s face. I knew I had to explain immediately. “But Dad, I had the highest score in the calss,”I proudly stated. I thought that explanation would make a difference.“You failed!”my father replied.“But it’s the highest!” I insisted.“I don’t care what scores others had, but you failed. What matters is what you do!”my father firmly said.
For years, my father was always that way. It didn’t matter what others did, it only mattered what I did and that I did it excelently.
We often don’t understand the wisdom(智慧)of good parents until we ourselves stand in the parents’shoes. My father’s words have carried me throughout life.
【小题1】 The word groaning is the closest in meaning to _____.

A.singingB.laughingC.complainingD.quarreling
【小题2】 In class, to hide my score from my classmates, I _____.

B.the writer was always poor in tests.
