        現(xiàn)在完成時(shí),但一般都這么說:have/has done,have/has been done,是現(xiàn)在完成時(shí)的被動(dòng)語態(tài)。現(xiàn)在完成時(shí)表示到說話時(shí)為止(或到現(xiàn)在為止)已經(jīng)發(fā)生或完成了(不一定結(jié)束)的動(dòng)作或狀態(tài)。過去某一時(shí)間開始并一直持續(xù)到現(xiàn)在,并且有可能還會(huì)持續(xù)的動(dòng)作或狀態(tài)。

        擴(kuò)展資料

          Have 表示動(dòng)作,如表示“吃(=eat)”“喝(=drink)”“拿(=take)”“收到(=receive)”“度過(=spend)”等時(shí),在用法應(yīng)注意以下幾點(diǎn):

          (1) 可用于進(jìn)行時(shí)態(tài),但一般不用于被動(dòng)語態(tài)。如:

          誤:Lunch is had by him.

          正:He is having lunch. 他在吃中飯。

          (2) 不與 got 連用。如:

          誤:I’d like to have got a look at it.

          正:I’d like to have a look at it. 我想看看它。

          (3) 一般不用縮略式。如:

          誤:We’d a good time at the party.

          正:We had a good time at the party. 我們?cè)谕頃?huì)上玩得很高興。

          (4) 構(gòu)成否定式和疑問式時(shí),必須用助動(dòng)詞 do。如:

          誤:When had you breakfast?

          正:When did you have breakfast? 你什么時(shí)候吃早餐?

          表達(dá)將來時(shí)的幾種結(jié)構(gòu):

          be going to do

          表示最近打算進(jìn)行的事,具有一定的目的性和計(jì)劃性.(這種安排既有可能是主語做出的,也有可能是別人安排 的)

          We are going to have a meeting tomorrow.

          表示即將要發(fā)生的事情,不可避免要發(fā)生的事情.(多用于表天氣)

          It's getting cloudy. It is going to rain.
