三.【語法詳解】used to, be used to, so…that, such…that　　
㈠used to, be used to的用法　　
⒈used to＋動(dòng)詞原形，過去常做某事；否定式為used not to do sth或did not use to do sth；疑問式為did…use to do sth?或used… to do sth? there be與used to的用法為：肯定式there used to be….；否定式there used not to be…或there did not use to be…；疑問式used there to be…? e.g. 　�、舠he used to live on her own.→否定式：①she used not to live on her own. ②she didn’t use to live on her own. →疑問式：①did she use to live on her own? ②used she to live on her own? 　　⑵there used to be a clock tower. →否定式：①there didn’t use to be a clock tower. ②there used not be a clock tower. →疑問式：①did there use to be a clock tower? ②used there to be a clock tower?　�、瞓e used to sth習(xí)慣某事，be used to doing sth習(xí)慣做某事，也可以表達(dá)為get/become used to sth, get/become used to doing sth。e.g. ①daniel is/gets/becomes used to the life in the city. ②she is/gets/become used to getting up early.　　㈡so…that, such…that的用法　�、眘o, such的用法：　　⑴so是副詞，修飾形容詞或副詞原級(jí)；such是形容詞，修飾名詞或名詞短語�！　、苨uch修飾含有名詞單數(shù)、名詞復(fù)數(shù)和不可數(shù)名詞的名詞短語，即：①such a/an＋形容詞＋名詞單數(shù) ②such＋形容詞＋名詞復(fù)數(shù) ③such＋形容詞＋不可數(shù)名詞�！　∽⒁庖韵绿厥馇闆r：such修飾名詞單數(shù)時(shí)可以轉(zhuǎn)換為so，但是詞序不同，即：such a/an＋形容詞＋名詞單數(shù)＝so＋形容詞＋a/an＋名詞單數(shù)。當(dāng)名詞前有many, much, few, little這四個(gè)詞修飾，只能用so，即so many/few＋名詞復(fù)數(shù)，so much/little＋不可數(shù)名詞；簡言之，so修飾“兩多”、“兩少”。例如：　�、賡uch a man ②such an exciting film＝so exciting a film ③such exciting films不能說成so exciting films ④such fine weather不能說成so fine weather ⑤so many/few books不能說成such many/few books ⑥so much/little pollution不能說成such much/little pollution�！　、瞫o…that…, such…that…如此…以至于…，引導(dǎo)結(jié)果狀語從句，兩者在意思上可以互換。such修飾名詞或名詞短語；so修飾形容詞或副詞原級(jí)。當(dāng)so前面的動(dòng)詞是連系動(dòng)詞時(shí)，so后面用形容詞原級(jí)；當(dāng)so前面是行為動(dòng)詞時(shí)，so后面用副詞原級(jí)；即：連系動(dòng)詞＋so＋形容詞原級(jí)，行為動(dòng)詞＋so＋副詞原級(jí)。so或such的使用是中考的一個(gè)重要考點(diǎn)。
