__he entered the university,his english has been much improved. A,after B,since
问题描述:
__he entered the university,his english has been much improved. A,after B,since
为什么A不对?
我看其他问题上说是完成时,所以用B
那如果用A该怎么用?
谢谢
答
B,since 为正确选项.
请留意句子的后半部分,用了现在完成时,这是句子要用since的重要标志.after是不能与现在完成时连用的.
请楼主记住:现在完成时+since+一般过去时.这一重要句型.那能不能把这道题变成用after的例子??谢谢。。。可以,就用一般过去时:After he entered the university,his English was much improved.
