(2) That she is still alive is a puzzle. 3. 宾语从句就是在复合句中作宾语的名词性从句, 通常放在主句谓语动词 (及物动词) 或介词之后。 (1) 由that 引导的宾语从句(that通常可以省略), 例如： I heard that he joined the army. (2) 由what, whether (if)引导的宾语从句, 例如： ① She did not know what had happened. ② I wonder whether you can change this note for me. 4. 否定的转移: 若主语谓语动词为think, consider, suppose, believe, expect, guess, imagine等, 其后的宾语从句若含有否定意义, 一般要把否定词转移到主句谓语上, 从句谓语用肯定式。 I don’t think this dress fits you well.
