2020屆高考英語名詞性從句語法復習
4. 注意賓語從句中的時態呼應,當主句動詞是現在時,從句根據自身的句子情況,而使用不同時態。例如:
he studies english every day. (從句用一般現在時)
he studied english last term. (從句用一般過去時)
i know (that) he will study english next year. (從句用一般將來時)
he has studied english since 1998. (從句用現在完成時)
當主句動詞是過去時態(could, would除外),從句則要用相應的過去時態,如一般過去時,過去進行時,過去將來時等;當從句表示的是客觀真理,科學原理,自然現象,則從句仍用現在時態。例如:the teacher told us that tom had left us for america.
5. think, believe, imagine, suppose等等動詞引起的否定性賓語從句中,要把上述主句中的動詞變為否定式。即將從句中的否定形式移到主句中。例如:
we don’t think you are here. 我們認為你不在這。
i don’t believe he will do so. 我相信他不會這樣做。
6.時態:1.主句用一般現在時,從句可用任意時態。2.主句用過去時,從句用過去某個時態。
3.主句用過去時,從句是客觀真理時,只用一般現在時。
