此題考察的除了do 表示強調以外,還有就是一般過去時態(tài)與現在完成時態(tài)的區(qū)別:一般過去時只表示發(fā)生在過去的動作或存在的狀態(tài),不涉及對現在的影響;現在完成時表示過去發(fā)生的動作或狀態(tài)一直延續(xù)到現在,或表示過去發(fā)生的動作對現在造成影響.
I ____this afternoon,but you were out.題中只是在敘述今天下午的事,并沒有涉及到對現在的影響,或是這個狀態(tài)一直延續(xù)到現在.所以天did call
I ____this afternoon,but you were out.
I ____this afternoon,but you were out.
空格處為何用did call而不用have called?
