我又忍不住要说了。1。c. it it没有具体意思，指代时间而已。例如： It is 5 years since his grandfather died.2.b. how long ago how long ago was that? (how long ago指多久前，that指代摔交受伤事件）3。b. that, which that引导一个定语从句，修饰先行词these days ，在从句中作宾语。即：I spent these days with the farmers。 which 引导的一个定语从句是非限制性定语从句，修饰these days that I spent with the farmers

1. The boy dived into the water and after __ seemed to be a long time , he came up again.灰灰的答案是正确的。我在补充一下：it 经常用作 seem ，appear ,look和happen 的主语。这个句子主要结构是The boy dived into the water and he came up again.after it seemed to be a long time 是一个由after引导的从句。what可以引导名词性从句但是还没看到过在哪个句子中单独做主语.

这几道题：灰灰回答的有误，我同意NN6 的答案。1。 what seemed to be a long time what 是“。。。的样子”的意思。过了很长时间的样子，做的是AFTER 的宾从。同理： He stands on what seems a stone after bathing.2\3 同NN6

1.what是seem的主语2.b.过去时 how long was it ago3.b spent是vt.要跟宾语,后一半是非限制性定于从句,不可用that,只能用which

3.b that为先行词用法which 为非限定性定语从句

1. a. what seemed to be是插入语，去掉不影响句子基本意思2. b. how long ago指多久前，问过去发生的事的时间3. b. 前一个that指these days, 后一个which指前面这件事。
