方法：将直接引语变为由if或whether引导的宾语从句跟在引述动词之后。如：

“Is it cheap?” she asked. 她问：“它便宜吗?”

→She asked if [whether] it was cheap. 他问这东西是否便宜。

“Do you like it?” she asked. 她问：“你喜欢它吗?”

→She asked if [whether] I liked it. 他问我是否喜欢它。

“Did he leave yesterday?” she asked. 她问：“他昨天离开了吗?”

→She asked if [whether] he had left the day before. 她问他是不是前一天离开了。

“Can you tell me more?” she asked. 她问：“你能多告诉我一些情况吗?”

→She asked if [whether] I could tell her more. 她问我能不能多告诉她一些情况。

注：改为宾语从句的间接引语要用陈述句词序。
