瑞文問答

2024-06-11

is being done為被動(dòng)語態(tài)。以do為例,各種時(shí)態(tài)的被動(dòng)語態(tài)形式為:am/is/are+done(過去分詞)一般現(xiàn)在時(shí)。例句:Visitors are requested not to touch the exhibits.has/have been done.

  表達(dá)將來時(shí)的幾種結(jié)構(gòu):

  1、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.

  2、be to do:

  表示按計(jì)劃要發(fā)生的事,一般認(rèn)為,這種計(jì)劃是雙方約定的,而 be going to do所指的安排不一定是雙方約定的。

  We are going to meet them at the north of the bridge,because it is the only road they can follow.

  We are to meet each other with them at the north end of the bridge.

  雙方約定好要在橋的北邊見面。

  3、be to do還有很多情態(tài)用法,be going to do沒有以下用法。

  You are to wash your hands before every meal.(表需要=need)

  As Warrent's parents,you are to set a good example to him.(表責(zé)任,義務(wù),相當(dāng)于,must,should)
