注:若enough前出現(xiàn)否定詞,則不僅否定了enough,而且也否定其后的不定式:He was not strong enough to do the work. 他不夠強壯,不能做這工作。
另外,該句型有時可與so [such]…that結(jié)構(gòu)轉(zhuǎn)換:
He is rich enough to buy a plane. 他很有錢,可以買一架飛機。
→He is so rich that he can buy a plane. 他很有錢,可以買一架飛機。
有時該句型也可與too…to句型轉(zhuǎn)換:
He is too young to go to school. 他太小,還不能上學(xué)。
→He is not old enough to go to school. 他還不夠大,還不能上學(xué)。
enough作形容詞,意思是"足夠的;充分的",常與for或不定式連用,可以作定語或表語。作定語置于被修飾的名詞前后均可,前置時強調(diào)enough,后置時強調(diào)被修飾詞。
例句:So what is good enough for you? 所以什么對你來說是足夠好呢?
