A
I first went to Harrow in the summer term. The school had the biggest swimming pool I had ever seen. It was a good joke to come up behind a naked boy, and push him into the pool. I made quite a habit of this with boys of my own size or less.
One day I saw a boy wrapped in a towel on the side of the pool. He was no bigger than I was, so I thought him a fair game. Coming secretly behind, I pushed him in, holding on to his towel so that it would not get wet, I was surprised to see an angry face come out from the water, and a being of great strength making its way by fierce strokes(猛力地划) to the shore. I tried to run away, but I failed. He overtook me, caught me violently, and threw me into the deepest part of the pool. I soon climbed out on the oth er side, and found myself in a crowd of younger boys. “Do you know what you have done?” they said, “It’s Amery; he is in Grade Six. He is champion at gym, he has got his football honor.”
I was frightened and felt ashamed. How could I tell he was champion when he was wrapped in a bath towel and so small? He didn’t seem pleased at all, so I added in a most brilliant word, “My father, who is a great man, is also small.” At this he laughed, and after some words about my rude behavior and how I had better be careful in the future, the incident was closed.

A. looked like an animal

B. wanted to amaze Amery
C. tried to frighten Amery
D. looked down upon his father
54. Which of the following is TRUE?

People who show confidence really seem to have it made. They seize more rewarding careers, keep good relationships, and just seem to do everything with more styles than the rest of us.
So what is the secret? There isn’t one. Self-confidence is a skill and habit that anyone can learn to develop. And although people who are raised in an encouraging environment with confident role models have a hard start in self-confidence development, we all can learn to become more confident at any age.
Try these simple tips for practising and increasing your self-confidence levels: Dare t o fail. Anybody who’s out there bravely performing is going to fail repeatedly. If you are not failing, you are not trying. So don’t take failure too hard or too personally. Just learn to deal with it and use its lessons to keep improving.
When in doubt, pretend you know what you are doing. Because, if you are confident of your abilities, by the time you have done it, you will be experienced. Dress for success. Y ou don’t have to be beautiful to be confident. Make the most of your own unique physical characters and weaken your disadvantages.
Listen to yourself. Y ou are the only person who knows what’s right for you. Don’t put others’ opinions above your own inner voice.
Build a confident vocabulary. Stop putting yourself down and give up continually blaming your tiny weaknesses. Learn to show up your strong points and the world will learn to see and celebrate them with you.
Pass on the praise. Praise others for their virtues and strengths. This practice will not decrease your confidence, but help increase it.
56. The passage is written mainly __________.
A. to explain the definition of self-confidence
B. to explain the secret of self-confidence
C. to tell people how important self-confidence is
D. to tell people how to build self-confidence
57. The underlined word “one” in the second paragraph refers to __________.
A. the secret of self-confidence
B. the skill of self-confidence
C. the style of doing things
D. a rewarding career
58. The main idea of the sixth paragraph is __________.
A. to be confident means to have no disadvantages
B. taking full advantage of your physical characters will help you be confident
C. your unique characters will help you be confident and be successful
D. to be confident means to be beautiful
59. All the following are tips to increase your self-confidence level EXCEPT_________.
A. not to be afraid of failure
B. dress yourself properly
C. pretend to know everything
D. make your advantages more obvious
60. __________ will weaken your self-confidence.
A. Praising others for their strong points
B. Always following others’ advice to do things
C. Giving up blaming your weaknesses
D. Believing in yourself
C
阅读下面的短文，并根据短文后的要求答题。(请将答案写在答题卡上相应番号后的横线上)
Many of us do not like what we see around us but the last thing we ever do is to change it. I think that is the beginning of failure and that is why what we hate still remains around us.
We have such an amazing creative power inside us to change the way things work around us. Only people who like finding excuses go about saying that that is the way things have always worked.
Before you think too much about all the changes you want to make, let me help you by saying that your habits should change first. Change what you think abo ut and change what you talk about. Change the things that get your attention before you plan to change the world.
If it is not so easy to change yourself when you want to, it is not going to be easy to change the people around you. Many people do not find it easy to change themselves yet still want to change the world. I think the best way I have changed the people around me is __________________.
People are watching you. Some of them do not expect you to change, so your change may seem like a miracle (奇迹) to them. When you change, they will change. Just change yourself and see how many people will tell you later that you were the one who changed them.
That is one of the simple ways a young person can change the world.
