阅读下面的诗歌,完成1~4题。
鱼化石
动作多么活泼,精力多么旺盛,在浪花里跳跃,在大海里浮沉;
不幸遇到火山爆发,也可能是地震,你失去了自由,被埋进了灰尘;
过了多少亿年,地质勘查队员在岩层里发现了你,依然栩栩如生。
但你是沉默的,连叹息也没有,鳞和鳍都完整,却不能动弹;
你绝对地静止,对外界毫无反应,看不见天和水,听不见浪花的声音。
凝视着一片化石,傻瓜也得到教训:离开了运动,就没有生命。
活着就要斗争,在斗争中前进,当死亡没有来临,把能量发挥干净。

题型:阅读理解

We would probably all be amazed if we watched a videotape of ourselves performing basically unconscious acts as we go about the business of the day. These unconscious acts consist of all the little personal habits that we don’t even think about, but definitely should. These are some of the things that present an image of who we are to others, and if we are careless in performing them, this image may well be other than we would like it to be.

Parents who insist that their children practice good manners and habits at home are doing them a great service, for these habits then become lifelong and the natural way they do things. It proves true that their unconscious actions will reflect a well-mannered person.

People who, for example, eat with both arms on the table at home will likely do so when out. Those who are lazy and slow in private will certainly be so in public. Children who are permitted to be disrespectful to their parents will follow suit with other adults, and will, most likely, become adults who are disrespectful of others. This is an area where the saying “practice makes perfect” may be applied.

There is an article about the actress, Audrey Hepburn, known for her beautiful carriage and posture. According to her biographer, her grandmother tied her neck to the back of her chair, at table, so that she would not drop down suddenly over her food, but rather would learn to put only small amounts of food on her spoon or fork and bring them to her mouth. This is a rather extreme “at home” method for the development of erect (直立的) posture, but it does illustrate the effectiveness of practicing good habits so that, when in public, they are instinctive.

小题1:

Which of the following expresses the main idea of the passage?

A.Parents should be responsible for their children’s good habits.

B.The actress is well known for her beautiful posture.

C.We should always be aware of our manners.

D.Without good manners, one can never be perfect.小题2:

Those who eat with both arms on the table at home ______.

A.will probably have the same habit when they have meals in the restaurant

B.will probably change the habit when eating out with their relatives

C.will feel embarrassed when having meals with so many strangers in public

D.will always put their arms on the table no matter where they eat小题3:

The meaning of “practice makes perfect” in the third paragraph is ______.

A.the more practice one has, the better job he will do

B.the more perfect one is, the more practice he needs

C.if one has enough practice, he will become perfect

D.perfect makes a person practice more小题4:

Which of the following are NOT true?

A.If we are not careful about our unconscious acts, the images of ourselves presented to others will be quite undesirable.

B.The good habits formed in one’s childhood will benefit him throughout his life.

C.If parents do not care about the disrespectful attitude adopted by their children towards themselves, their children might be disrespectful of others.

D.It is unlikely that a well-mannered person will not embarrass himself in public.
