【本讲教育信息】
一. 教学内容:
Chapter Four: language and speaking
二. 重点、难点
1. 祈使句(Imperative Sentence)
定义:祈使句是用来表达命令、请求、劝告、警告、禁止的句子。祈使句最常用于表达请求、命令。
(1)祈使句因对象(即主语)是第二人称,所以通常都省略。祈使句的动词都为动词原形,句末则使用句号来表示结束。如:
Go and wash your hands. 去洗你的手。(表命令)
Be quiet, please. (Please be quiet.) 请安静。(表请求)
(2)肯定结构:
①Do型(即:动词原形+宾语+其他成分)。如:
Please have a seat here. 请这边坐。
有的祈使句在意思明确的情况下,动词可以省略。如:
This way, please. = Go this way, please. 请这边走。
②Be型 (即:Be+表语+其他成分)。如:
Be a good boy! 要做一个好孩子!
③Let型(即:Let+宾语+动词原形+其他成分)。如:
Let me help you. 让我来帮你。
(3)否定结构:
① Do 型和Be型的否定式都在句首加don‘t构成。如:
Don‘t forget me! 不要忘记我!
Don‘t be late for school! 上学不要迟到!
② Let型的否定式有两种:
“Don‘t+let+宾语+动词原形+其他成分“和“Let+宾语+not+动词原形+其他成分“如:
Don‘t let him go. / Let him not go.别让他走。
③有些祈使句可用no开头,用来表示禁止。如:
No smoking! 禁止吸烟!
No fishing! 禁止钓鱼!
(4)“Let“开头的祈使句
由“Let“开头的祈使句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“。
在此句型里,let后面要跟第一人称的代词宾格形式。如:
Let me try.
该句型语气委婉,比Don‘t开头的祈使句客气。试比较:
Don‘t disturb him. Let‘s not disturb him.
②表示“间接命令“或“愿望“。
在此句型中,let后面要跟第三人称代词宾格形式或名词。如:
Just let her try! 就让她试试吧!
Let each man decide for himself. 让每个人自己决定吧!
(5)使用“let“的祈使句时,必须注意以下几点:
①“let“的否定式有两种形式:“Don‘t let ...“和 “Let ... not“。
如果宾语是第三人称用“Don‘t let ...“;如果宾语是第一人称,则用“Let...not“。 如:
Don‘t let this type of things happen again.
It‘s raining now. Let‘s not go out until after the rain.
②“Let“适用于现在时态,可以有被动语态。如:
Let the recalcitrant criminals be sent to prison.
Let all the dedicated capable staff be promoted.
③“Let“后面跟不带“to“的不定式,还可以是某些副词:out,in,down,alone等。 如:
Let the puppy out.
Open the windows and let the fresh air in.
The room is too sunny. Let the blinds down.
Let me alone, please.
④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:
Let‘s try it, shall we?
Let us do it by ourselves, will you?
2. David, pay attention. 大卫,请注意。
pay attention to 注意......
pay attention to your pronunciation. 请注意你的发音。
