| B. | which method should I use to solve the problem. | |
| C. | that which method to solve the problem. | |
| D. | which method to use to solve the problem. |
分析 我不确定用哪种方法去解决问题.
解答 答案:D.be sure后加宾语从句,引导词+陈述句语序,故排除A(引导词多了that),B(语序错误),这里也可以用疑问词+to do sth作为宾语,故排除C.故选D.
点评 本题旨在考查宾语从句这一语法,做这类题时,要从三方面考虑:一、选准连接词 二、连接词后紧跟从句的主语 三、若主句是过去时,从句要改为相对应的过去时.
