题目内容
3.This math problem is very difficult.I don't know .Oh,you can ask your math teacher for help.( )
| A. | what should I do | B. | how should I do | ||
| C. | what to do it | D. | how to do it |
分析 --这道数学题太难了.我不知道如何做它.
--哦,你可以向你的数学老师寻求帮助.
解答 答案:D.
根据I don't know ?再结合选项,可知I don't know 后面是跟一个宾语从句,宾语从句中应该用陈述语序,即主语+谓语,所以排除AB.do是个及物动词,后面应该跟宾语,what是个疑问代词,可以作宾语,后面不需要再加it,而how是个疑问副词,需要加it.故选:D.
点评 主要考查宾语从句,一定要注意宾语从句的引导词,以及宾语从句的时态和语序问题.把握好这几点,是做好此类题目的关键!
