“两招定向”解决语法填空中的介词问题
1.分析句子成分
如果句子中不缺少主语或表语,动词后又不缺少宾语,则在名词、代词或动名词前一定是填介词。
对点训练
①She patted him on the head and said, “My little boy, do you feel more comfortable now than before?”
②But can uniforms help improve school standards? The answer to this question is not clear.
③If you could exchange lives with someone for a short time, would you like to do that?
④If you are not going to suffer this problem, then I suggest that the next time you go to your mum's home for dinner, and get a few cooking tips from her.
2.牢记搭配
(1)注意短语搭配中介词的正确使用;
(2)注意有特殊用法的介词,如接复合宾语就只能用with或without。
对点训练
①As a result, he spends his life in a wheelchair and cannot write by means of a pen or pencil.

③After school she plans to take a year off to model fulltime before going to university to get a degree in engineering or architecture.
