【延伸阅读】
A recent British study examined the salaries(薪水) and jobs of people who spent time enjoying the arts when growing up. They found those who enjoyed the arts from an early age had better jobs and higher salaries than those who didn’t.
What’s the link(联系)?How could visiting a museum, enjoying a symphony(交响乐),or improving painting skills lead to career(事业) success?
Other studies have found that students who study the arts exercise their reasoning(推理) ability. This skill helps with problem-solving. Creative and critical-thinking abilities are also developed through art study. When faced with a real-life challenge(挑战),these skills can be put to good use.
The best kind of art excites our imagination and makes us think. Paintings aren’t just pretty pictures. They tell stories about the experience of the painter. See Michelangelo’s(米开朗基罗) art, and you will taste the power of his faith in God. Look at the world from Picasso’s point of view, and you see everyday life in new ways. In Shakespeare’s plays you’ll find lessons about character and morality(人格及道义).Chinese poet Li Bai brings the wonder of nature’s beauty to every reader.
The arts show and explain the world beyond our own personal knowledge. When we look beyond ourselves, we can appreciate the experience of people from different walks of life. The arts help develop the ability to see things from many different points of view. These things will help us better communicate and cooperate with other people.
What are Li Bai’s poems about?
Key: Nature.

I made a promise to myself on the way down to the vacation beach cottage. For two weeks I would try to be a loving husband and father. Totally 21 . The idea had come to me as I listened to a commentator (解说员) on my car's tape player. He was 22 a passage about husbands' being 23 of their wives. Then he went on to say, "Love is an act of will. A person can 24 to love."
To myself, I had to admit that I had been dulled by my own insensitivity ( 感觉迟钝). So I would like to 25 . And it did. Right from the moment I kissed Katherine at the door and said, "That new yellow sweater looks 26 on you." "Oh, Tom, you noticed." She said, surprised and 27 .
After the long drive, I wanted to sit and read. Katherine suggested a walk on the beach. I started to refuse, but then I thought, "Katherine's been 28 here with the children the year round." We walked on the beach while the children flew their kites. We visited the shell museum though I usually hate museums. Relaxed and happy, that's how the whole 29 passed. I made

分析文章语境可知：在汽车里的磁带播放机中解说员在读一篇文章。

23. C。

根据下文来看，应是：关心，体贴(thoughtful) 才对。

24. B。

上一句讲到爱是出于自愿的行为，那么就应choose to love了。

文章最后一句也有呼应。

25. B。

由文章可知，作者决心在海滨度假的这两个星期内，这一切都要改变。

26. A。

吹捧人常用great一词。

27. C。

Everyday we go to school and listen to the teacher, and the teacher will ask us some questions. Sometimes, the classmates will ask your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat（闲谈）with friends — you are in a slightly unnatural situation where a large group of people will remain silent, waiting to hear what you have to say. You must speak so that they can hear you — loudly enough and clearly enough but without trying to shout of appearing to force yourself.
Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you. The person you are seeing will try to put you at your ease（轻松）but the situation is somewhat（一点儿）different from that of an ordinary conversation. You must take special care that you can be heard.
46.When you speak to the class, you should speak _______________.
A．as loudly as possible B．in a low voice
C．loudly D．forcefully
ually, when you speak to the class, the class is _________________.
A. noisy B．quiet C．having a rest D．serious
48.The situation in the class is _______________ that in your house.
A．not very different from B．sometimes the same as
C.．sometimes not the same as D．not the same as
49. If you are having a conversation with an official, the most important thing for you is _______.

C. to make sure that you can be heard D．to put the official at ease
50.The main idea of this passage is _______________.
A．that we must use different ways at different situations B．that we must speak loudly C．that we must keep silent at any time D．that we must talk with the class
【答案与解析】46—50 DCCBD
46.C。

细节理解题。

根据文章第一自然段中的：You must speak so that they can hear you—loudly enough and clearly enough but without trying to shout or appearing to force yourself. 可以看出C 项为正确答案，而A、B、D三项均与这句话意义不符，可排除。

47.B。

细节理解题。

从文中的…where a large group of people will remain silent，可见B项为正确答案。

这里的silent与选项中的quiet同义，均意为“安静”。

48.D。

事实判断题。

文章第一自然段告诉我们：在班上讲话不同于在家中谈话或闲聊，当有一大群人安静下来，等待你的讲话时，你会感到有点不自然，由此可见，D项为最佳选项。

49.C。

推理判断题。

文章最后一句：You must take special care that you can be heard.你应特别注意你会被别人听到。

很清楚地交代了答案应选C项。

这里take special care意为“特别注意，特别重视”。

50.A。

主旨大意题。

纵观全文，不难得出这样一个结论：在不同的场合应采取不同的说话方式。
