染雾英语语法知识讲解之解析祈使句 篇一
祈使句是一种特殊的句子类型，用于表达命令、请求、建议或劝告等意义。在祈使句中，谓语动词通常省略，使用动词原形或动词词组作为句子的谓语。本文将为您详细解析祈使句的用法和特点。
首先，祈使句的基本结构是：动词原形或动词词组 + 其他成分。例如，在命令句中，我们可以说：“Close the door.”（关上门）这里，“Close”是动词原形，句子的主语和谓语之间没有任何其他成分。
其次，祈使句的主语通常是第二人称，即“你”。但是，在某些情况下，祈使句的主语可以省略。例如，“Sit down.”（坐下）这里省略了主语“你”，但是仍然能够明确表达命令的意义。
此外，祈使句的否定形式通常是在动词前加上“don't”。例如，“Don't be late.”（不要迟到）这里，“be”是动词原形，否定形式是在动词前加上“don't”。
在使用祈使句时，我们需要注意以下几点：
1. 注意动词的形式。在祈使句中，动词通常使用原形，不带任何时态、人称和数的变化。例如，“Please be quiet.”（请安静）这里，“be”是动词原形，不带任何变化。
2. 注意语气和语调。祈使句通常用于表达命令、请求或建议等，因此在使用祈使句时，我们需要注意语气和语调的正确运用。例如，在请求句中，“Please help me.”（请帮助我）中的“please”可以加强请求的语气。
3. 注意上下文。祈使句的意义通常依赖于上下文，因此在使用祈使句时，我们需要考虑上下文的影响。例如，在“Pass me the salt.”（把盐递给我）中，“pass”是命令的动词，但是上下文的影响使得这句话成为了一种请求。
总之，祈使句是一种常用的句子类型，用于表达命令、请求、建议或劝告等意义。在使用祈使句时，我们需要注意动词的形式、主语的省略、否定形式的构成以及语气和语调的运用。通过正确使用祈使句，我们可以更好地表达自己的意思并与他人进行有效的交流。

初三英语上册知识点：Let引导的祈使句
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”。
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 marketing department.
(6) Let her join our choir.
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 invaders 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 recalcitrant criminals be sent to prison.
(12) Let all the dedicated capable staff be promoted.
三、"Let"后头除了是不带"to"的不定式动词 (The infinitive 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。
