5. What do you think of John Smith?

[答案及解析]

通读全文, 故事讲述的是车站搬运工John Smith有一天在火车站同一名旅客间的一段对话，故事很幽默。

第一个问题是一个细节题，第1段清楚地说明了他的工作：John Smith was an old porter。porter的意思的“(车站、码头) 的搬运工人”，如果考生不认识这个词，也可以由He worked at the station. Every day he was busy carrying heavy things for the people.这两句话了解他的工作性质。因此第一个问题的回答：John’s job was to carry heavy things for the people at station. / He was a porter.

第二个问题是一个推理题，问题:这名旅客要去哪里。由文中这句旅客的问话Can I catch the 10:35 train to London?很容易推断出他要去伦敦。

第三个问题仍要求考生推理得出答案，问题：为什么此人看上去很急的样子朝火车赶去。很显然是因为他在赶火车。对why提问要用because进行回答，第三个问题的回答是Because he wanted to catch the 10:35 train to London.

第四个问题是推理题, 问的是：这名旅客赶到火车站的时间。由下文John的回答The 10:35 train to London left five minutes ago可知火车已开走，这名旅客赶到的时间是大约10_: 40，因此第四题的回答是It was about10：40 (twenty to eleven) 。第五个问题是归纳题, 考查考生对文章大意的理解。这个问题的回答实际上就是全文的中心句, 在第一自然段里已做了介绍。He was careful with his work. He was kind to everyone and always ready to help others.

(B)

John Brown, an office worker, lives in Washington, He inherited(继承) $ 1,000, 000 when he was 23. He didn’t feel happy at all. His college friends were looking for their first jobs, but he didn’t have to. John decided to keep living a simple life like everyone else. He didn’t tell any of his friends and gave $ 100, 000 of his money to a charity(慈善团体) that helped poor children to live better lives, but he is much happier.

Up to now,John has helped 15 children from poor coun­tries all over the world, $ 200 a month for each. The child does not receive the money in cash(现金). The money pays for the child’s school expenses, food, medical care and cloth­ing. John receives a report each year on the child’s progress. They can write to each other, but usually the children do not speak English.

When John first heard about these children, he wanted to help them. “It was not anything special,” he said, “Until I had the chance to go to these countries and meet the children I was helping, I did not know anything about the type of life they had.”

Once John went to meet a little girl in Africa. He said that the meeting was very exciting. “When I met her, I felt very very happy,”　 he said, “I saw that the money was used for a very good plan. It brought me closer to the child in a way that giving money alone cannot” “ I want to do every­thing I can. I will go on helping those children in need, “he added.
