B,since 為正確選項.
請留意句子的后半部分,用了現(xiàn)在完成時,這是句子要用since的重要標(biāo)志.after是不能與現(xiàn)在完成時連用的.
請樓主記?。含F(xiàn)在完成時+since+一般過去時.這一重要句型.那能不能把這道題變成用after的例子？？謝謝。。?？梢?，就用一般過去時：After he entered the university,his English was much improved.
__he entered the university,his english has been much improved. A,after B,since
__he entered the university,his english has been much improved. A,after B,since
為什么A不對?
我看其他問題上說是完成時,所以用B
那如果用A該怎么用?
謝謝
