He says he has drink his milk.這句是什么時態(tài)?
新概念一,第102課,課后練習(xí)：
書中給出的例句：He is drinking his milk.
改成間接引語后：He says he has drink his milk.
這個間接引語我會改,我不懂的是這句中的has drink his milk中的has是什么作用,這句中我也知道has是have的第三人稱單數(shù)形式,那如果換成其他人稱如第三人稱復(fù)數(shù),they say they have drink their milk.這里have drink是什么意思,drink本身都是喝了,為什么還有個have.原句中到底has是干什么的.
以下是給出的題：
1、she is shutting the door.
改后：she says she has shut the door.
2、he is putting on his coat.
改后：he says he has put on his coat.
3、he is reading this magazine.
改后：he says he has read this magazine.
4、they are speaking to the boss.
改后：they say they have spoken to the boss.
5、the sun is rising.
改后：they say the sun has risen.
改過后的句子中都有have/has,很糊涂.
