  由"let"带头的祈使句(imperative sentences)是个常见的动词句型,它的主要用法有下列三种:
  1.表示“建议”。

  这个句型里的"let"后头紧跟着一个第一人称的代词宾语,如:

  (1) let me try.

  (2) let"s do it.

  (3) let me go and look for it.

   这个句型语气委婉,比直接的祈使句客气。试比较(4)a和(4)b:

  (4) a. don"t disturb him.

   b. let"s not disturb him.

  (a)是直接命令,语气强烈,不如(b)温柔悦耳。

  2.表示“间接命令”或“愿望”。

  这句型里的动词宾语是第三人称名词或代词,如:

  (5) let robert take charge of the 1 department.

  (6) let her join our 2.

  3.表示“警告”、“蔑视”、“威胁”等。

  这种祈使句里的宾语也是第三人称为主。除了口气凶悍之外,有时还语带讽刺,如:

  (7) let him try and he will expose his inability to work on his own.

  (8) let the 3 come and our armed forces will wipe them out in no time.

  用"let"的祈使句时,必须注意下列几点:

  一、"let" 的否定句有二。如果宾语是第三人称用"don"t let....."(见例(9));如果宾语是第一人称,则用"let......not" (见例(10)):

  (9) don"t let this type of things happen again.

  (10) it"s raining now. let"s not go out until after the rain.

  二、"let"只适用于现在时态,可以有被动语态 (the passive voice),如:

  (11) let the 4 criminals be sent to prison.

  (12) let all the 5 capable staff be promoted.

  三、"let"后头除了是不带"to"的不定式动词 (the 6 without"to")之外,还可以是某些适当的副词,如out, in, down, alone等:

  (13) let the puppy out.

  (14) open the windows and let the fresh air in.

  (15) the room is too sunny. let the blinds down.

  (16) let me alone, please.

  四、用"let"s"时,把谈话者的对象包括在内;用"let us"时,并不包括对方,如:

  (17) let"s try it, shall we?

  (18) let us do it by ourselves, will you?

  从(17)里的"shall we"和(18)里的"will you",不难知道前者包括听话人,后者并没有。
