14、(劝告) Watch your steps. 走路小心。(警告) Look out!Danger!小心!危险!(强烈警告,已如感叹句) Keep off the grass. 勿践踏草坪。(禁止) No parking. 禁止停车。(禁止) 祈使句也常把主语“You”表达出来,使对方听起来觉得柔和些,例如: You go and tell him, Chris. 克立斯,你去告诉他。 二.表现形式 肯定结构: 1. Do 型 (即:动词原形(+ 宾语)+ 其它成分) 。如:Please have a seat here.请这边坐。有的祈使 句在意思明确的情况下,动词可省略。如:This way
15、, please. = Go this way, please. 请这边 走。 2. Be 型( 即:Be + 表语(名词或形容词 )+其它成分) 。如:Be a good boy! 要做一个好孩子! 3. Let 型 (即:Let + 宾语 + 动词原形 + 其它成分) 。如:Let me help you. 让我来帮你。 否定结构: 1. Do 型和 Be 型的否定式都是在句首加 dont 构成。如:Dont forget me! 不要忘记我! Dont be late for school! 上学不要迟到! 2. Let 型的否定式有两种:“Dont + let + 宾语 + 动词原形
16、+ 其它成分”和“Let + 宾语 + not + 动词原形 + 其它成分”。如:Dont let him go. / Let him not go. 别让他走。 3. 有些可用 no 开头,用来表示禁止性的祈使句。如:No smoking! 禁止吸烟!No fishing! 禁 止钓鱼! 练习:将下列汉语翻译成英语。 1. 请照看好您的包。 2. 让我们去学校吧! 3. 亲爱的,高兴点儿! 4. 不要把书放这儿。 5. 不要让猫进来。 “let“带头的祈使句 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” 。
17、 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) Lets 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. Dont disturb him. b. Lets 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 marketing departme
18、nt. (6) Let her join our choir(合唱团). 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(暴露)his inability(无能)to work on his own. (8) Let the invaders(侵略者) 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
19、称用“Dont let.“(见例(9));如果宾语是第 一人称,则用“Letnot“ (见例(10)): (9) Dont let this type of things happen again. (10) Its raining now. Lets 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 recalcitrant criminals(反抗的罪犯) be sent to prison. (12) Let all the dedicated(贡献)
20、capable(能力) staff(职员) be promoted.(提升) 三、“Let“后头除了是不带 “to“的不定式动词之外,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(窗帘)down. (16) Let me alone, please. 四、用“Lets“时,把谈话者的对象包括在内;用 “Let us“时,并不包括对方,如:
21、 (17) Lets 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“,不难知道前者包括说话人,后者并没有。 数 词 (numeral) (一)基数词 在英语中表示数目的词称为基数词。 1基数词的构成 (1)1-20 one,two,three ,four,five,six ,seven,eight ,nine,ten,eleven ,twelve,thirteen ,fourteen,fifteen ,sixteen,seventeen,eighteen

35、这些图片中的“6”所示。然而,他 们几乎都用相同的方法来计数十进制。 零 我们中的大多数人使用 1 到 9 和 0 的数字系统。有了这 10 个数字以后,我们可以写 出从最大到最小的任何一个数字。印度人最早发明并完善了 1 到 9 的数字系统。之后他们 又发明了 0。这是一个伟大的发明。因为它使得人们书写大的数字和计算更为容易。 计算工具 算盘是最早的计算工具之一。用算盘计算快且正确,以致于人们今天仍然在使用它们。 现代化的电子计算器可以做加、减、乘、除运算。它还可以计算百分数和平方根。 电脑是十分强大的计算工具。一瞬间,电脑就可以完成一道你可能花一辈子的时间也 未必能做完的计算题。 人脑对决
