1 It is ____that we will never forget

1 It is _A_that we will never forget
A such a nice city B a such nice city C so a nice city
so 后面跟形容词 eg:So beautiful a girl!
such 后面紧跟名词 eg：Such a beautiful girl!
2 There used to be a house _A___on the top of the mountain
standing 作定语,非谓语,而且形容的一个状态故ing
3 I think he must be in the office now,__C_____?
A donot I B mustnot he C isnot he
此类句,I think we think 都类似装饰品要忽略,
must 在这里是表猜测的用法,后面的 be才是王,
就算是must作必须意讲,反义也是用needn't.
4 There are three ___A___assistants in that ____shop
A women ;shoe B women ;shoes C woman;shoes
是个比较特殊的用法,凡遇 女医生女教师等等,名词修饰名词,复数形式是俩名词统统复数,故women,
我也晓得没有人只买一只鞋,但是就是shoe shop or shoe store
别加s
