水吸到气管、肺里面去会令人发呛,如果只在人的鼻子里装点水而没让他吸进去,他也不会发呛。大象就是一个例证。如果你细心一点观察,会发现大象在饮水时是先用鼻子吸一点水(并没有吸到肺里去),然后抬起头来,把鼻子里的水放到嘴巴里去喝。在此过程中,它只是把鼻子作为吸水的工具,而并没有把鼻子当成饮水的器官。这段话要论证这样一种观点:

A.你必须细心一点观察

B.大象的鼻子是取水的工具

C.大象喜欢用鼻子吸一点水放到嘴里去喝

D.水吸到气管、肺里面去才会发呛

A few days ago, I went to school with lots of books,hoping to get a locker (锁柜). Suddenly, it started raining heavily. I hurried to pay for my locker, but I was disappointed when they informed me they only accepted cash. I was $ 7.00 short, which meant I had to carry the books back home. It would be an exhausting (令人精疲力竭的) two-hour journey back home with all those books.

An elderly gentleman nearby noticed my problem. He asked how much cash I needed. When I told him I was $7 short, he quickly took out the money from his wallet .“You don’t have to pay me back ,”he said. I was speechless; I didn't know whether to take the money or come back with the books the next day. A young student who was working there noticed my hesitation. “He’s really nice ,”said the student. I was starving this morning and he bought breakfast for me. He always helps people in different ways.

The next day, I went to him and thanked him for trusting me and lending me the money. He said he forgot about it and didn't expect I would give it back. “I’m very happy,” he said,“not because I’m getting my money back, but because this is the right way to go---whatever you get from this world, give it back as much as you possibly can. Spread kindness around the world with the smallest things you can do.”

Later, I found out he wasn’t involved with any charity(慈善)organizations. He has been performing these types of acts for years. Earlier, someone had done something incredibly kind for him and he has been spreading the kindness ever since.

He taught me a very important lesson in life. We come to this world with nothing and we will leave with nothing. Whatever we own, it will become somebody else’s and whatever we leave, it will become somebody else’s.
