  11. as 可以用于哪些结构中引导定语从句?

  such... as the same... as so ... as..

  12. the same...as和the same ...that 引导的定语从句如何区别?

  the same...as 引导的定语从句指的是相同事物,强调同类.the same...that 引导的定语从句指的是同一物.

  This is the same pen as I bought yesterday.(相同)

  This is the same pen that I borrowed from Mr. Li. (同一物)

  13. such...as ...和such...that...如何区分?

  such...as ...引导的是定语从句.as必须代替先行词在其引导的从句中充当

  成分.such...that...引导的从句是状语从句.that只是引导从句并不在其引导的从句中充当成分.在选择填空练习题中,首先看从句中是否缺句子成分,如果缺成分就要考虑是定语从句;如果不缺成分就要考虑是状语成分.

  14. whose 引导定语从句有那些注意点?

  whose 作定语,后面跟名词.一般有三种表示形式. 例:

  This is the dictionary whose cover has come off.

  = This is the dictionary the cover of which has come off.

  = This is the dictionary of which the cover has come off.

  15. 主语从句主要用于哪些句型中?

  It is + (名词、形容词、过去分词+ that ...

  It seems(mattes / happened) that...

  16. that 在名词性从句中应注意哪些问题?

  ★that在主语从句、表语从句、同位语从句中(除宾语从句)即使不充当成分,that 不能省。

  ★在等表示命令、请求、建议等动词后的宾语从句中that不能省。

  ★在6123结构中,引导宾语从句的that不能省。

  ★由and或or所连接的两个宾语从句时,第一个从句中的that可以省;而第二个从句中的that不能省。

  ★that 引导的宾语从句,如果从句中还有其它状语从句,引导宾语从句的that不能省。
