从句 分类
从句 特点
1: 陈述语气
一般来说,把一个疑问句变化成陈述语气 只要将时表词跟主语换个位置就行。
I don't know + where did he go?
--> 变成:
I don't know where he did go?
-->变成:
I don't know where he went?
2: 连词
(1)从句是陈述句:
我知道他是个老师
I know that he is a teacher
(2)从句是一般疑问句:
我不知道他是不是老师
I don't know if he is a teacher
(3) 从句是特殊疑问句
我不知道他是谁。
I don't know who he is .
主语从句
连词--that
连词-- weather /if
注意:
1: 做主语从句的时候不能用if,if放在前面容易跟如果混淆。
2: 主语从句谓语动词三单
