水吸到气管、肺里面去方令人发呛，如果只在人的鼻子里装点水而没让他吸进去，他也不会发仓。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 mother and daughter living in my community are two of the most unfriendly people I have ever come across in my life. They are totally 1 , mixing with nobody. As they drive past neighbors they keep their eyes looking away and make no sign of 2 . The only fame they have is making a nuisance (讨厌的人) of themselves to the local police station by 3 music played too loud, dogs barking more than once a day and any other petty (琐碎的) little 4 . On moving into this neighborhood, I was 5 of these two but decided I would make up my own mind. This proved quite a 6 to me as more than once either the mother or the daughter would knock on my door and blast (猛烈抨击) me with some 7 or other. I 8 answered politely and made sure I 9 as they went past my place and also made the effort now and then to make a kind 10 about their garden or pets. Time passed and in October, as part of the Kindness Rock Give, Maureen and I decided to place a kindness rock in their garden. Their 11 remained unchanged, however, and I continued to be as friendly as possible. During the Easter give, we decided once again to 12 these two unhappy ladies to our list and 13 a packet of cookies on their gate. Imagine my 14 when two days later they 15 at my gate and jokingly said they were 16 hanging their Christmas stocking on their gate, and they brought me a bunch of flowers! So, my fellow gifters, do not 17 on your random gifts of kindness. You may never know just what this 18 to others, nor how many broken or 19 hearted people you may just change 20 a simple act of kindness. | ||||
