四.【中考无敌语法】祈使句、情态动词should, shouldn’t, must, mustn’t
㈠祈使句
祈使句是表示请求、命令、建议等的句子，通常也称“无主句”。句子的主语是第二人称you，you常被省略。句尾可以用感叹号或句号。祈使句有三种形式：肯定式、否定式、let引导。
⒈肯定祈使句：这种祈使句是初级英语中常见的句式之一，有时为了加强语气，在动词原形前加do或在句尾加上称呼语。有时为了表达客气的语气，常在句首或句尾加please；在句尾加称呼语时，要用逗号将其与句子的前部分隔开。e.g.
①Write the new words in your notebooks. ②Please open the window. ③Do make sure to call me.
⒉否定祈使句：在动词原形之前加do not, don’t或never，就变成了否定的祈使句。e.g.
①Don’t stop reading. ②Do not leave the stove on. ③Never give up.
⒊Let引导的祈使句：以let引导的句子也是祈使句，常用于表示建议或表明说话者的态度。e.g.
①Let’s go out for a walk. ②Let me help you. ③Let us discuss how to do it.
㈡情态动词should, must的用法
⒈should应该；应当，表示劝告、建议、命令，否定式为shouldn’t。e.g. ①You should learn their advanced experience from them. ②You shouldn’t feed your dog at the table.
⒉should可能，表示推测。e.g. ①They should be there by now, I think.我想他们现在可能到那里了。②Daniel is an Aquarius. He should be kind and wise.丹尼尔是水瓶座，他可能善良、聪明。
⒊must必须；应该，表示做某事非常有必要或很重要。
⒋must表示推测，意为“一定”，仅用于肯定句中。表示对现在的推测用“must＋动词原形”，表示对过去的推测用“must have＋过去分词”。e.g.
①You must be tired after a long journey. ②It’s 9:00p.m. She must have come home.
⒌mustn’t表示“禁止；一定不要；不可以”。e.g. You mustn’t play computer games too much.
【比较】can’t表示推测时，意为“不可能”，与must(一定，表推测)互为反义词。e.g.
That man can’t be Mr Smith. He has gone to the USA on business. He won’t return until the end of this month.
