以定语从句这一项为例。把"I read a novel yesterday.和"It was extremely Interesting."这两个单句改为"The novel I read yesterday was extremely interesting."这就是定语从句的单项练习。首先要反复进行替换练习。如把"I saw a man this morning."和"The man is my teacher."改为"The man I saw this morning is my teacher."把"I saw a film last night."和"The film was very amusing."改为"The film I saw last night was very amusing."这种练习虽然是枯燥的,却是重要的基本功,务求把定语从句练到脱口而出的地步。这是第一步。
第二步是把定语从句放在一定的语言情景中去综合运用,进行一问一答。如:
A:Did you enjoy the opera?
B:Which opera?
A:The one we saw last night,of course.
B:Yes,very much.
第三步是扩大运用,也就是把定语从句和以前学过的两三个项目放在一起去操练。
A:Do you know who Edgar Snow was?(一般问句;名词从句)
B:Yes,he was an American writer who interviewed Chairman Mao in Beijing.(定语从句)
A:Oh,now I remember.He was the author who wrote"Red Star Over China",wasn't he?(定语从句;反意疑问句)
