一、阅读理解（共1道小题，共25.0分）

1. Sixty-year-old grandmother, Fiona McFee, is going to stop working next year and she

decided to realize a childhood dream and sail around the coast of Scotland in a small boat.

Although the inside of the boat is very cosy, it has no running water or electricity. Fiona says she can live without these things but she plans to take her small CD player, her hot water bottle and

a bag of books to make sure lif e isn’t too uncomfortable.

We asked her if she was afraid of being at sea for so long. She said, “Well, I’m going to take

a good compass (指南针). Anyway I’m not afraid of death because I love the sea---I just hope it

loves me.”Fiona certainly has plenty of energy; in her spare time, she enjoys playing the

piano, rock-climbing, canoeing and dancing. Although she is sixty, she doesn’t want to have a

quiet and peaceful life. “I’m looking forward to having fun in the rest of my life and that’s exactly why I’d like to be a sailor for a while.”

1. The underlined word cosy in the first paragraph means ____ .

A. bright

B. dirty

C. comfortable

D. dark

2. When Fiona McFee said “---I just hope it loves me”, what she meant was ____.

A. Of course, it loves me, since I love it.

B. If I love it, it should love me.

C. I hope it will bring me a safe sailing as a return for my love of it.

D. I hope it will save my life when I am in time of danger.

3. The reason why she would like to have the sail is that ____.

A. she thinks it will be very exciting

B. she likes sports and enjoys canoeing

C. she has decided to love the sea

D. she wants to be still active when she gets old

4. What kind of person would you say the old woman is?

A. Someone who does not show what she is feeling.

B. Someone who is very proud and sure of her success.

C. Someone who doesn’t use her head much.

D. Someone who is open, honest and brave.

5. The best title for this passage is ____ .

A. Life Begins at Sixty

C. An Old Woman Sailor

D. An Unusual Hobby(爱好)

试题分值：25.0

得分：[5, 5, 5, 5, 5]

提示：[1]C.词汇题。本题问“第一段的‘cosy’是什么意思？”解决词汇题的思路是先找到该词语出现的句子。该句大意是“虽然船非常的‘cosy’，但是船上并没有自来水和电力”。这里来看前面半句讲的应该是这条船的优点，而后半句讲的是这条船的不足，这里是通过前后的对比来猜测词义。据此可以推测“cosy”的意思是C。

[2]C.推断题。本题问“当Fiona说：‘我只是希望大海也爱我’的时候，她的意思是_______。”答案

在第二段的第三句，该句大意是“Anyway I’m not afraid of death because I love the s ea---I just

hope it loves me.不管怎样，我并不惧怕死亡，因为我爱大海――我希望大海也爱我”。据此可以推测答案是C（我希望大海可以保佑我的航行平安，作为我爱它的回报）。A的意思是“因为我爱大海，所以大海当然爱我”，B的意思是“如果我爱大海，大海就会爱我”，D的意思是“我希望在我遇到危险的时候，大海能够救我”。

[3]D.推断题。本题问“Fiona想要航海的原因是_______。”答案在最后一段的最后两句，这两句大

意是“Fiona精力特别充沛，在闲暇的时候她喜欢弹钢琴，攀岩，划独木舟和跳舞。虽然年届60，但是她并不想过那种安静祥和的生活。‘我喜欢我的后半生能过得有趣点，这就是为何我想要做一回航海家的原因’”。据此可知答案是D（她想在年纪大的时候还能充满活力）。

[4]D.推断题。本题问“你认为Fiona这个老太太是什么样的人？”根据我们上面几题的解释，我们

可以得出答案是D（她是个开放，诚实，勇敢的老太太）。A的意思是“她是个不敢表露真实想法的人”，B的意思是“她是个特别骄傲，对成功特有把握的人”，C的意思是“她是个不太会用大脑的人”。

[5]A.中心思想题。本题让我们给文章选个最好的标题。A的意思是“生活在60岁才开始”，B的意

思是“一次环绕海岸的航行”，C的意思是“一位老年女航海家”，D的意思是“一个不寻常的爱好”。

第一段的第一句告诉我们Fiona在60岁的时候决定要做一次航海，第二段告诉我们Fiona并不畏惧航海中的危险，而且她想让自己的后半生更有乐趣。据此我们可知A最适合做本文标题。

1. People have been talking about health for a long time because people know the importance of it. People's understanding of health also becomes deeper with the progress in scientific research. Recently the term "health" has come to have a wider meaning than it used to. It no longer means just the absence of illness. Today, health means the well-being of your body, your mind and your relationship with other people. This new concept of health is closely related to another term----quality of life. Quality of life is the degree of overall satisfaction that a person gets from life. Why has the emphasis of health shifted from the absence of disease to a broader focus on the quality of a person's life？One reason for this has to do with the length and conditions of life that people can now expect. Medical advances have made it possible for people today to live longer, healthier lives. Imagine for a moment that you were born in the year 1900. You could have expected on average to live until about the age of 47. In contrast, if you were born in the year 1999, you could expect to live to the age of 75. 2. 1. ______leads to people's deeper understanding of health. 2. https://www.wendangku.net/doc/4916264928.html,mon knowledge 2.Progress in scientific research 3.Better conditions of living 4.Quality of life 3. According to the passage, to people of today, health means______. 4. 1.absence of illness 2. a long life 3.good conditions of living 4.overall satisfaction with life

、阅读理解（共1道小题，共25.0分） 1. 2. The market is a concept. If you are growing potatoes for sale you are producing for the market. You might sell some to your neighbor and some to the manager of the local supermarket. In either case you are producing for the market. Your efforts are being directed by the market. If people stop buying potatoes you will stop producing them. If your sister looks after a sick person to make money she is also producing for the market. If your brother is a steelworker or a bus driver or a doctor he is producing goods or services for the market. When you spend your income you are buying things from the market. You may spend money in stores gas station and restaurants. Still you are buying from the market. When the local grocer hires you to drive the delivery lorry he is buying your labor in the labor market. The market may seem to be something abstract.
