be?.；否定式There used not to be?或There did not use to be?；疑问式Used there to be?? e.g.
⑴She 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. →疑问式：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. →疑问式：①Did there use to be a clock tower? ②Used there to be a clock tower?
⒉be used to sth习惯某事，be used to doing sth习惯做某事，也可以表达为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 ⒈so, such的用法：
⑴so是副词，修饰形容词或副词原级；such是形容词，修饰名词或名词短语。
⑵such修饰含有名词单数、名词复数和不可数名词的名词短语，即：①such a/an＋形容词＋名词单数 ②such＋形容词＋名词复数 ③such＋形容词＋不可数名词。
注意以下特殊情况：such修饰名词单数时可以转换为so，但是词序

不同，即：such a/an＋形容词＋名词单数＝so＋形容词＋a/an＋名词单数。当名词前有many, much, few, little这四个词修饰，只能用so，即so many/few＋名词复数，so much/little＋不可数名词；简言之，so修饰“两多”、“两少”。例如：
①such a man ②such an exciting film＝so exciting a film ③such exciting films不能说成so exciting films ④such fine weather不能说成so fine weather ⑤so many/few books不能说成such many/few books ⑥so much/little pollution不能说成such much/little pollution。
⒉so?that?, such?that?如此?以至于?，引导结果状语从句，两者在意思上可以互换。such修饰名词或名词短语；so修饰形容词或副词原级。当so前面的动词是连系动词时，so后面用形容词原级；当so前面是行为动词时，so后面用副词原级；即：连系动词＋so＋形容词原级，行为动词＋so＋副词原级。so或such的使用是中考的一个重要考点。
⑴The problem is so difficult that we can’t work it out.＝It is such a difficult problem that we can’t work it out. 注意：so?that?转换为such?that?，必须保持意思不变。 ⑵Many patients are so poor that they can’t afford to go to hospital.

⑴The book cost so much that she couldn’t buy it.＝The book cost too much for her to buy.
