中级美国英语 第四十三课-VOA中级美语

一.本课要点及示例

在这一课里, 我们学习用 "如果" if, i-f, if 和过去完成时态作句子来表示跟过去事实相反的条件和结果.比方,"当时我要是看见了你,我一定会跟你打招呼的."这句话英文应该这样说: If I had seen you. I certainly would have said hello to you. 下面我们念一段对话, 多举几个例子给你听.这段对话的内容是说凯特跟同事比尔谈起了他们小时候上历史课的事情. 请你注意听两位英文老师的发音和语调.

M: When did you decide to be a school teacher,Kate?
F: When I was in grade school, I had a teacher who I liked very much. I wanted to be like
　 she was.
M: What made her so special?
F: She used to make things interesting and exciting to learn.
M: Like what?
F: If you had heard her history lessons, you would have thought that history was ascinating. M: If you had been in our history class, you would have found history very boring. Our
　 teacher just taught names and dates.
F: If I had been in your class, maybe I would have become something besides a teacher.
M: If I had been in your class, maybe I would have become a history teacher instead of a
　 gym teacher.

现在我们把对话再念一遍给你听. 这次老师念得比较慢, 请你注意听.

M: When did you decide to be a school teacher,Kate?
F: When I was in grade school, I had a teacher who I liked very much. I wanted to be like
　 she was.
M: What made her so special?
F: She used to make things interesting and exciting to learn.
M: Like what?
F: If you had heard her history lessons, you would have thought that history was ascinating. M: If you had been in our history class, you would have found history very boring. Our
　 teacher just taught names and dates.
F: If I had been in your class, maybe I would have become something besides a teacher.
M: If I had been in your class, maybe I would have become a history teacher instead of a
　 gym teacher.

下面两位老师把对话里包含了今天要学的语法的句子挑出来,再念一遍给你听.

F: If you had heard her history lessons, you would have thought that history was ascinating. M: If you had been in our history class, you would have found history very boring.
F: If I had been in your class, maybe I would have become something besides a teacher.
M: If I had been in your class, maybe I would have become a history teacher.

二.用 IF 引导跟过去事实相反的情况

听了上面那些句子, 我想你已经注意到怎么样用过去完成时态作句子来表达跟过去事实相反的情况. 现在我们开始作练习, 多学学这种说法. 第一组练习的作法是比尔用过去时态说明发生在过去的事情. 凯特就用过去完成时态作假设性句子, 说明如果比尔过去那么作了, 他可能会有什么结果. 下面就是一
个例子:

M: I wasn't in your class. I didn't become a history teacher.
F: If you had been in my class,maybe you would have become a history teacher.

现在请你一边听句子的意思, 一边注意语法的变化.

M: I wasn't in your class. I didn't become a history teacher.
F: If you had been in my class, maybe you would have become a history teacher.
M: I wasn't in your class. I didn't think that history was fascinating.
F: If you had been in my class, maybe you would have thought that history was fascinating.
