九年级上学期英语课文知识点所谓垂悬结构(The DanglingConstruction)就是一个句子成分,如分词短语,不定式动词短语等,找不到被修饰的主语或被修饰的对象不合逻辑。垂悬结构是种错误的句法,应该避免。
下面是三种常见的垂悬结构及其改正方法:
⒈垂悬分词或分词短语,如:
①Climbing up the hill, several boars were seen.
这句子里的现在分词短语(present participial phrase)修饰主语“several boars”是错的;改正方法有二:
(a)确定是逻辑主语,使句子变成“Climbing up the hill, the explorers saw severalboars.”
(b)把现在分词短语扩大为副词分句(也称状语从句):“When the explorers climbed up the hill, they saws ……此处隐藏1144个字……John are not certain whether to get married or not.
适用于“疑问词+不定式动词”的动词包括:“know, see, decide, tell, ask, consider, discover,explain, forget, guess, hear, imagine, inquire, learn, remember, think, wonder,understand”等。
有点值得特别注意的是:当这结构当宾语时,它的作用等于名词分句,例如:
I could not decide which dictonary to buy./ I could not decide whichdictionary I should buy.
Jack did not know where to find such a good teacher./ Jack did not knowwhere he could find such a good teacher.
有些动词,如“ask, show, tell, advise, inform,teach”等,可以先有个宾语,然后才接着加上适当的“疑问词+不定式动词” 结构。例如:
The chief technician showed the apprentice how to repair the machine.
Have you told him where to get the application form?
