高中英语:两个“at”的用法
第一个句子:If she were my daughter,I wouldn't let her stay out the whole night.
提问:可不可以在stay out和the whole night中间添加at
第二个句子:By coincidence,oil paints were also developed at this time,which made the colour used in paintings look richer and deeper.
提问:可不可以去掉句中的at
▼优质解答
答案和解析
1.不可以,the whole night 是个时间副词,不需要接介词
2.可以,如time作时间的意思,需有介词at,当time做次的意思,this time就可以
