英语宾语从句怎么去理解

运用宾语从句时注意的问题
1.引导词的选择
陈述句充当宾语从句用that
一般疑问句充当宾语从句用if或whether
特殊问句充当宾语从句用疑问代词或疑问副词
2.语序：陈述句语序
3.时态：主句是一般现在时从句就按实际情况用相应时态
主句是一般过去时从句用相应的过去某种时态
4.当主句谓语动词为think,suppose,expect,believe 等时,其后的宾语从句为否定句时,常将否定词not从从句中移到主句中,构成否定转移
5.如果从句说的是客观现象或真理,无论主句是什么时态,从句都用一般现在时.
I think that he will come back in a
week.
The policeman wanted to know if you were at
home at nine yesterday.
I asked him where the meeting would be held.
