What can't you do on the road?你（们）不能在马路上做什么？ 1.祈使句 祈使句用于表示命令、请求、建议、劝/警告等语气。它的主要作用是向对方提出某种要求或建议，希望对方采取某种行动或避免某种行为。祈使句通常省略主语，以动词原形开头。有的时候为了表示礼貌也会在句首或者句末加上“please”。 例如：Look at the traffic lights. They're red now.看交通信号灯。它们现在是红色的。 Cross the road now, please.现在请过马路吧。 祈使句的否定形式是在句首加don't. 例如：Don't cross the road now.现在不要过马路。 Don't run on the road.不要在马路上奔跑。 在本单元，我们还接触到了祈使句的一种特殊结构“let sb. do sth.”让某人做某事。在这种句型中，有明确的指代对象，可以用于建议、请求或允许，语气较为委婉。let's是let us的缩写形式，意为“让我们……”。 例如：Let's take a bus to the zoo.让我们乘公共汽车去动物园。 Let me look left and right first.让我先左右查看一下。 2.情态动词can的用法 情态动词can用于表达能力、许可、可能性等多种语气，常用于口语中。它没有数和人称的变化，后面直接加动词原形。can的否定形式是can't或cannot，用于表示不能、不允许或不可能。 例如：You can go to the zoo by taxi.你可以乘坐出租车去动物园。 You can't play football here. It's dangerous.你不能在这里踢足球，很危险。 基础提优 一、读一读，根据句意从方框中选择含有与画线字母相同发音的单词，补全句子，注意大小写。 road so robot cold close home rope 1. Oh! Don't jump the __________ on the __________. 2.
