在刚才那组练习里我们用 "也许" maybe 加上 would 再加上完成时态作了一 些假设性句子, 这种说法也可以改用 might 加上完成时态来表达. 比方:
Maybe he would have become a history teacher. 可以改为 He might have become a history teacher. 下面我们作一组练习把这两种说法作个比较.首先 请你注意听老师用第一种说法说一句话,然后请你跟学生一起改用代名词跟 第二种说法把那句话表达出来.下面就是一个例子:
M: If Bill had been in Kate's class, maybe he would have become a history teacher.
F: If he had been in her class, he might have become a history teacher.
现在我们开始作练习.
M: If Bill had been in Kate's class, maybe he would have become a history teacher.
F: If he had been in her class, he might have become a history teacher.
M: If Bill had been in Kate's class, maybe he would have thought that history was fascinating.
F: If he had been in her class, he might have thought that history was fascinating.
M: If Bill had been in Kate's class, maybe he would have thought that history was exciting.
F: If he had been in her class, he might have thought that history was exciting.
M: If Kate had been in Bill's class, maybe she would have become a gym teacher.
F: If she had been in his class, she might have become a gym teacher.
M: If Kate had been in Bill's class, maybe she would have thought that history was boring.
F: If she had been in his class, she might have thought that history was boring.
M: If Kate had been in Bill's class, maybe she would have thought that history was just names and dates.
F: If she had been in his class, she might have thought that history was just names and dates.
下面我们用美国历史作例子, 学学跟过去事实相反的说法. 练习的作法是老 师用过去时态说出美国历史上的一项事实,比方"移民来到美洲; 殖 民地因此 成立." The immigrants came to America. The colonies were established. 学生 就把句子改成:"如果移民没有到美洲, 殖民地就不会成立." If the immigrants hadn't come to America, the colonies wouldn't have been established. 在这组练 习里有些新词汇,比方 "压迫" oppress, "革命" revolution,"打败" defeat,"奴隶" slave 等等. 请你注意听. 学生作句子的时候请你也一起作.
