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: 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。 点击收听单词发音
