It was the last day of the final examination in a college. On the steps of a building, a group of engineering students were waiting for the last exam. On their faces was confidence.

    They knew the exam would be easy. The professor had said they could bring any books or notes during the test.

    Right after they came into the classroom, the professor handed out the papers. There were only five questions on it.

    Three hours passed. Then the professor began to collect the papers.  The students no longer looked confident. On their faces was nervous expression. The professor watched the worried faces before him, and then asked, "How many of you have completed(完成) all five questions?" No hand was raised. "How many of you have answered four?" Still no hands.  "Three? Two?" The students moved restlessly in their seats. "One, then? Certainly somebody has finished one. "But the class kept silent. The professor said, "That is exactly what I expected. I just want to make you know clearly that even though you have completed four years of engineering, there are still many things about the subject you don't know. These questions you could not answer are common in everyday practice. "Then, smiling, he added, "You will all pass this course, your education has just begun."

    The years have obscured the name of this professor, but not the lesson he taught.

    In Singapore, many middle school students spend a lot of their time on their studies. Good education is often regarded as a ticket to success in their future. So, many of these students try their best to get a good mark in their examinations. They have a lot of homework every day and exams are a big headache. Sometimes, some of them are even made to go to remedial (补习的) classes after school.

    Schools run programmes outside school hours. The students can take part in sports and games, music and dance, hiking and rock-climbing, etc. They are also very active in community service(社区服务).

    In their spare time, most students like to listen to pop music. Hollywood blockbusters(大片), Hong Kong and Singapore movies are very popular among them. They understand IT very well. Some of them also spend their free time surfing the Internet, e-mailing their friends, playing computer and video games.

    They sometimes go to cafes, fast-food restaurants, shopping centers and big bookstores.

    So, it looks like life as a middle school student in Singapore is not easy but it is rich and colorful.

      Do you knowwhy different animals or insects have their special colors? Colors are   u mainly to protect themselves.

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

       I  you study the animal life, you'll find the main use of coloring is to protect themselves. Bears, lions and other animals move  t forest quietly . They cannot be easily seen by hunters .This is because they have the colors much like the trees.

      Have you  e noticed an even more strangething? A kind of fish in the sea can send out black liquid(液体) when it faces   d. While the liquid spreads over, its enemies can't find it. And it swims away   i. So it has lived up to now though it is not strong at all.

      The problem started when the family moved and Chris switched schools. He made friends with new kids, some of whom used drugs(毒品) . The first time Chris used cocaine（可卡因） was with friends at Larry's house. Everyone pooled their money to buy few grams of cocaine. Larry told them, “It's safe as long as you don't use it too often. It won't  turn you into an addict(成瘾者) like other drugs.

      During the following year, the group tried crack (价格不贵的强效纯可卡因)) along with cocaine. Chris bragged (吹嘘)， “I can handle this material!” Larry agreed. “As long as you only take a little bit, you'll be okay. He said. When one friend died in the hospital from an overdose(过量)，Chris thought, “That'll never happen to me. Since I'm mostly smell the drug, I won't have any problems.

       At 16, he lefthome without telling them where he was going. Just because his parents tried to change his mind .He lasted two weeks working at a pizza shop , and then he started selling cocaine. “I'll only do this until I get back on my feet(独立的)," he told himself.

      Chris's family found him living alone in a rundown(荒芜的) part of town. A school friend had called the family to tell them where he was. “It probably saved my life,”Chris says. “I was half-dead.”

      To pay for Chris to enter a drug treatment center, his dad took a second job. Chris is grateful to getting treatment. Now he's able to see colors again. In the depths of his addiction he saw everything in black and gray.

          MichaelLeung, a famous TV host in Hong Kong, wrote a letter to his son. It's not only hto children, but also good for all ages. The following are chosen f his letter.

         Life is short. While you’re wasting it today, you'll r you are at the end of it tomorrow. So the earlier you start to value your life, the earlier you can e it. You might not be successful iyou don't study hard, although a lot of successful people haven't

r higher education. I don't expect you to support me for the rest of m life,so I'm not going to do the same for you. You will be living on your own when you grow up. You can require yourself to be nice to others, b  you shouldn't expect the same from others. I've been buying the lottery(彩票) for almost 20 y, but I'm still poor. I have never even got third place. So you have to work hard to besuccessful. There's no f lunch in the world.
