一、祈使句 1)定义:又叫命令句,用来表示请求、命令、劝告或禁止等语气,句末用叹号或句号。 2)特点: ① 通常省略主语yu,也就是听话者。 ② 谓语动词没有人称、数的变化,时态为一般现在时,因此以动词原形开头。
为了使表达更礼貌,更客气,常在句首或句末加上please,若在句末加please,之前要用逗号隔开。
Wash yur hands.
Please be quiet
Be plite and kind.
Watch yur step
⑴ 肯定祈使句的常见句型结构: ① D型: 动词原形+宾语+其他. e.g. Open the dr, please. ② Be型: Be+表语(名词或形容词). e.g. Be quiet! Be a gd by!
4)句子结构 祈使句有肯定祈使句与否定祈使句两种。
有时,为了加强语气,可以在动词之前加d,意思为“一定,务必” 等。 D sit dwn. 务必请坐。 D study hard. 一定要努力学习。
③ Let型:(有两种) a. Let + 宾语 + 动词原形 + 其他. e.g. Let me help yu. b. Let’s + 动词原形 + 其他. e.g. Let’s play tennis.
let's VS let uslet's...意思是"让我们..." ,表示建议,通常包括听话者在内。let us ... 意思是"让我们..." ,不包括说话的对象,常表示请求。e.g. D yu like the mvie? let's enjy it Let us see the mvie if yu dn't like it .
⑵ 否定祈使句的常见句型结构: (祈使句的否定形式一般在句首加dn't。) ① D型的否定式:Dn’t + 动词原形 。 Dn’t frget me. ② Be型的否定式: Dn’t + be+其他. Dn’t be late.
有时为了加强否定语气,也可在句首加上never,表示“决不”。 Never leave tday's wrk fr tmrrw.
③ Let型的否定式:(有两种) a. Dn’t + let + 宾语 + 动词原形 + 其他. (宾语是第三人称) Dn’t let him g back. b. Let’s + nt + 动词原形 + 其他.(宾语是第一人称) Let’s nt g swimming.④ 警示语:N+名词 / 动词-ing形式. 如: N pht ! N talking.
一般来说,祈使句总是以动词原型开头,但有时在口语中,为了表达简洁,直接用名词或短语来表示祈使句的意义,如: eg: 救命! Help! 请等一会。 One mment, please. 举起手来。 Hands up!
二、情态动词can的用法 1) 表示能力 “会, 能” Can yu play the guitar? 你会弹吉他吗? Jim can speak Chinese.吉姆会说中文。
2) 表示允许、许可, “可以”、“能” Can the students run in the hallway ? We can eat utside. 我们可以在外面吃东西。
注意: 和大部分情态动词一样, 变否定句, 直接在can后加上nt, 在疑问句中, 把can放到主语前面, 并且没有人称和数的变化。
三、have t的用法 表示客观的必要性:“必须,不得不”,在一定意义上与must可以互换。must没有人称,数和时态的变化。have t有人称,数和时态变化。 We have t d hmewrk after schl. She has t be quiet in the library. D yu have t g t schl n time? They must be n time fr class.
注意: have t在否定句中, 直接在have t前面加dn’t/desn't, 在一般疑问句中, 在主语前面加助动词d/des, 有人称,数和时态的变化。
四、询问和讨论学校规则: 1. ━有什么规则?━我们必须保持安静。 _______________________________________ 2. ━我们可以在上课的时候戴帽子吗? ______________________________ ━不可以。你可以在外面戴帽子。 ___________ __________________________ 3. ━你必须做什么事? ______________________ ━我们必须穿校服。 ________________________________ 4. 他必须在校吃午饭吗? __________________________________
