Grammar 宾语从句 (2)由连接词if或whether引导的宾语从句: 其中if/whether意为“是否;是不是〞,宾语从句用陈述语序。 e.g.我不知道明天天气是否晴朗。 I don’t know if/whether it is fine tomorrow. 你知道他是否会来吗? Do you know if/whether he’ll come? whether和if在从句中不充当任何句子成分,只起连接作用,但不能省略。一般可以通用,但在以下情况下,whether不可换用if。 ①从句中有or not时; ②有些动词〔如discuss〕后面只能跟whether; ③从句充当介词宾语时; ④连接词后接不定式时。 1.We are sure that he ______________ (go) to school tomorrow. 2.Our father said that he ________(will) buy a new computer. 3.I heard that he ________(swim) in the s
