◆小学英语六年级情态动词
我们小学常见的情态动词有：
1.can 过去式(could),表示某人或某物能做某事。
例如；I can cook the meals. She can clean the room.
can的否定形式；直接在can的后面加not. 即can not/ can’t+ 动词原形。
2．may (might), may与can意思相近，表示可以，能。
例如；May I come in? 我可以进来吗？
3．must, have to的用法，两个都表示“必须”。must表示出于主观意识而必须要做have to 却表示由于某种客观原因。
例如：We must know the traffic rules.
My bike was broken. I have to walk to school today.
4．should 应该, will (would)。
5．情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语。情态动词后面跟动词原形。
◆我们学过以下情况动词用原形；
1.不定式to+动词原形
2.can/may/must/could/shoud等情态动词+动词原形
4.祈使句例如；D on’t open the door. 不要开门。
5.一般现在时，一般过去时，一般将来时的疑问句和否定句(do,does,did
don’t ,doesn’t ,didn’t)动词用回原形
6.be going to/will +动词原形(一般将来时）
7.let/make等使役动词+动词原形
8.help sb do sth帮助某人做某事。
