在做宾语从句的题目时应注意两点
1. 时态
①当主句是现在时态时,宾语从句可以根据需要使用任何时态。
I don't know when he will come back.我不知道他将何时回来。
He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。
②当主句是过去时态时,宾语从句必须是一种过去的时态。
She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。
He said that he could finish his work before supper.他说他会在晚饭前完成工作。
③当表示客观事实或普遍真理的句子做宾语从句时,任何时候都用一般现在时。
The teacher said that the earth goes round the sun.老师说过地球绕着太阳转。
2. 语序
任何从句都使用陈述句语序,宾语从句当然也不例外。 |
