小升初,祈使句精講及練習(xí)

1、小升初：祈使句精講及練習(xí)（含答案） 一、祈使句（Imperative Sentence ） 定義：用于表達(dá)命令、請(qǐng)求、勸告、警告、禁止等的句子叫做 祈使句. 祈使句因?qū)ο螅粗髡Z(yǔ)）是第二人稱，所以通常都省略。祈使句的動(dòng) 詞都為一般現(xiàn)在時(shí)，句末則使用句號(hào)來(lái)表示結(jié)束。 例：Go and wash your han ds.（去洗你的手。命令） Be quiet, please. （ Please be quiet.）（請(qǐng)安靜。一請(qǐng)求） Be kind to our sister.（對(duì)姊妹要和善。勸告） Watch your steps.（走路小心。一警告） Look out ！ Danger ?。ㄐ?/p>

2、心！危險(xiǎn)！ 一強(qiáng)烈警告，已如感嘆句） No parki ng.（禁止停車(chē)。一一禁止） 祈使句也常把主語(yǔ) “You”表達(dá)出來(lái)，使對(duì)方聽(tīng)起來(lái)覺(jué)得柔和些， 例如： You go and tell him, Chris.（克立斯你去告訴他。） 二、相關(guān)口令 祈使句無(wú)主語(yǔ)，主語(yǔ)you常省去； 動(dòng)詞原形謂語(yǔ)當(dāng)，句首加dont否定變； 朗讀應(yīng)當(dāng)用降調(diào)，句末常標(biāo)感嘆號(hào)。 三、表現(xiàn)形式 （一）肯定結(jié)構(gòu)： 1. Do型（即:動(dòng)詞原形 什賓語(yǔ)）+其它成分）。如:Please have a seat here. 請(qǐng)這邊坐。 有的祈使句在意思明確的情況下，動(dòng)詞可省略。 女口:This way, please. = Go

3、 this way, please. 請(qǐng)這邊走。 2. Be型（即:Be +表語(yǔ)（名詞或形容詞）+其它成分）。 如:Be a good boy!要做一個(gè)好孩子！ 3. Let型（即丄et +賓語(yǔ)+動(dòng)詞原形+其它成分）。如：Let me help you.讓我來(lái)幫你。 （二）否定結(jié)構(gòu)： 1. Do型和Be型的否定式都是在句首加 dont構(gòu)成。如:Dont forget me!不要忘記我! 2. Let型的否定式有兩種： （1） “ Dont + let +賓語(yǔ)+動(dòng)詞原形+其它成分” “Let +賓語(yǔ)+ not +動(dòng)詞原形+其它成分”。 如:Dont let him go. / Let him n

4、 ot go. 別讓他走。 3. 有些可用no開(kāi)頭，用來(lái)表示禁止性的祈使句。如:No smoking!禁止吸煙!No fishing!禁止釣魚(yú)！ 四、”let帶頭的祈使句 由let帶頭的祈使句（Imperative Sentences）是個(gè)常見(jiàn)的動(dòng)詞句型， 它 的主要用法有下列三種： 1. 表示建議”。 這個(gè)句型里的let后頭緊跟著一個(gè)第一人稱的代詞賓語(yǔ)，如： （1） Let me try. （2） Lets do it. （3）Let me go and look for it. 這個(gè)句型語(yǔ)氣委婉，比直接的祈使句客氣。試比較 （4）a和b: （4）a. Dont disturb him. b

5、. Lets not disturb him. （a）是直接命令，語(yǔ)氣強(qiáng)烈，不如（b）溫柔悅耳。 2. 表示間接命令”或愿望”。 這句型里的動(dòng)詞賓語(yǔ)是第三人稱名詞或代詞，如： (5) Let Robert take charge of the marketi ng departme nt. (讓robert接管市場(chǎng)部。) (6) Let her join our choir.(讓她加入我們的合唱團(tuán)。) 3. 表示警告”、蔑視”、威脅”等。 這種祈使句里的賓語(yǔ)也是第三人稱為主。除了口氣兇悍之外， 有時(shí)還語(yǔ)帶諷刺，如： (7) Let him try and he will expose his

6、in ability to work on his own. (8) Let the invaders come and our armed forces will wipe them out in no time. 五、用let的祈使句時(shí)，必須注意下列幾點(diǎn)： (一)、let的否定句有兩種。如果賓語(yǔ)是第三人稱用Dont let.(見(jiàn)例(9)；如果賓語(yǔ)是第一人稱，則用Let.not(見(jiàn)例(10): (9) Dont let this type of things happe n aga in. (10) Its raining now. Lets not go out until after t

7、he rain. (二) 、Let只適用于現(xiàn)在時(shí)態(tài)，可以有被動(dòng)語(yǔ)態(tài)(the passive voice)，如： (11) Let the man be sent to pris on. (12) Let all the excelle nt staff be promoted. (三) 、Let后頭除了是不帶to的不定式動(dòng)詞之外，還可以 是某些適當(dāng)?shù)母痹~，如out, in, down, alone (13) Let the man out. (14) Open the windows and let the fresh air in. (15) The room is too sunny. L

8、et the bli nds dow n. (16) Let me alone, please. (四)、用Lets時(shí)，把談話者的對(duì)象包括在內(nèi)；用 Let us時(shí)，并不 包括對(duì)方，如： (17) Lets try it, shall we? (18) Let us do it by ourselves, will you? 從(17)里的shall we和(18)里的will you，不難知道前者包括聽(tīng) 話人，后者并沒(méi)有。 祈使句練習(xí)一 1. The TV is too loud. Please. A. turn it down B. to turn it down C. turn down
