语法重点 1:由that, whether / if引导的宾语从句

宾语从句
1.引导词
2.时态
3.语序
that(陈述句)
if/whether(一般疑问句)
wh-(特殊疑问句)
主现从任(主句用一般现在时,从句任意时态)
主过从过(主语一般过去时,从句用相应的过去时态)
客观从现(从句表示客观真理、自然现象、公式定理,名言警句时,用一般现在时)
连接词之后用陈述语序(主语+谓语)
宾语从句三要素
一、由that引导的宾语从句
I think (that) mooncakes are delicious.
1.引导词
当宾语从句具有陈述意义时,用 that引导。that 无意义,在从句中不充当成分,在口语当中往往省略。
二、由if/ whether引导的宾语从句
I wonder if the weather will be cold tomorrow .
Miss Li asked if/whether they liked their new teachers.
从句的翻译有什么特点?
当宾语从句具有疑问意义时,用 if/whether引导,不省略。 译为“是否”
三、只用whether 不用if的情况
一前一后,做主语,连否定
1.在不定式前,只用whether 不用if
We haven’t decided whether to go there.
2.在介词之后,只用whether 不用if
It depends on whether it is going to rain.
3.做主语,只用whether 不用if
Whether he will come is not decided.
4.与or not 连用,只用whether 不用if
He asked me whether or not I agree with him.
if意为“假如,如果”时,引导条件状语从句,而whether不能引导条件状语从句。
如: If you go to the party,you will have a great time.
注意
2.时态
主现从任(主句用一般现在时,从句任意时态)
主过从过(主语一般过去时,从句用相应的过去时态)
客观从现(从句表示客观真理、自然现象、公式定理,名言警句时,用一般现在时)
