從句部分的連詞取決於從句時一般疑問句、特殊疑問句還是陳述句;
eg:We must find out who did all these.
I want to know whether he will come.
I hope that he will come.
① 賓語從句的時態:如果賓語從句前的動詞是過去式,則賓語從句的時態應相應變成過去時態;如果賓語從句是客觀事實或真理,不管賓語從句前的動詞時什麼時態,賓語從句都用一般現在時; eg:The teacher told us that the earth is round. eg:Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.
② 賓語從句後接陳述句,用that引導,則that一般可以省略; eg:I think that you are right.
③ 賓語從句如果謂語動詞是doubt,後面接的一般疑問句通常用weather或if引導;如果前面的謂語動詞是don't doubt,則後面從句的連接詞一定是that; eg:I doubt whether he is telling the truth. I don't that he is telling the truth.
賓語從句如果謂語動詞是wonder,句型為I wonder if,後面的連接詞不能用weather;
④賓語從句的否定轉移:
① think, believe, suppose, expect, fancy, imagine等動詞後面賓語從句的否定詞轉移到主句中,即主句的謂語動詞用否定式,而從句的謂語動詞用肯定式; eg:I don't think I know you.
I don' t believe he will come.
② 將seem, appear 等後的從句的否定轉移到前面。
It doesn't seem that they know where to go.
It doesn't appear that we'll have a sunny day tomorrow.
