Step 2 Grammar
祈使句
祈使句用来表示叮嘱、劝告、希望、禁止、建议、请求或命令等。它的常见句型有以下两种：
一、肯定式句型
1. Do型: 行为动词原形(+ 宾语 + 其他)。
如: Come in, please. = Please come in.
注意：please既可放在句末，也可放在句首。放在句末时，其前通常加逗号；放在句首时，它与动词原形之间不用逗号。
2. Be型: Be + 表语 (+ 其他)。
如：Be quick!
Be a nice man!
3. Let型: Let + 宾语 + 动词原形 (+ 其他)。
如：Let me have a try.
Let's go for a picnic.
二、否定式句型
1. Do型和Be型的否定式都是在句首加Don’t。
如: Don't talk in class.
Don't be sad.
2. Let型的否定式有两种：“Don’t +let+宾语+动词原形(+其他)”或“Let+宾语+not+动词原形(+其他)”。
如：Don't let them make noise in the library.
Let her not read in bed.
3. 在公共场所常常会见到一些警示语，其结构分别为“No+动词-ing形式”或“No+名词”。这些祈使句一般表示“禁止”或“规劝”的含义，用于警示人们不许做某事。
如：No parking!
No photos!
情态动词must, can, could表示推测
我们学过情态动词can和could表示“能够，可以”等意义的用法。can和could还可以表示对现在或将来的推测, 意为“会, 可能”。
can表示推测时，常用于否定句或疑问句中。
用于疑问句时，can比could表示的“可能性”要大; 用于否定句时，can’t (cannot) 意为 “不可能”。
e.g. You can’t be serious! 你不是认真的吧？
could表示推测时, 可用于肯定句、否定句和疑问句。
e.g. He could be in pain. 他可能很疼。
That could be harmful! 那可能有害！
Can/Could this be true 这有可能是真的吗？
情态动词must也可以表示猜测，意为“一定，准是”，通常只用于肯定句。
Betty, you must know! 贝蒂，你肯定知道。
