2.can 后跟动词什么形式
can为情态动词，跟的应该是动词的原形形式。
情态动词只有情态意义，即它所表示的是说话人对动作的观点，如需要、可能、意愿或怀疑等。 情态动词有以下特征： 1）在形式上，情态动词没有实义动词的各种变化，部分情态动词，如can、may、shall、will、have to、be to、dare等有时态的变化。
大部分情态动词的过去式是不规则变化，只有dare的过去式是规则变化，即dared。 2）在意义上，大多数情态动词有多个意义。
如can可表“能够”、“可能”、“允许”等，many可表“可能”、“ 允许”、“目的”、“让步”等。 3）在用法上，情态动词与助动词一样，须后接动词原形，构成谓语动词。
情态动词can的过去式为could，它的用法如下： 1）表能够。如： I can lift this stone. 我能举起这块石头。
（表体能） Can you use chopsticks？ 你能用筷子吗？（表技能） I can see him tonight. 我今晚能见到他。（表可能） can表能够时与短语be able to同义，但后者可用于各种时态。
can表能够时可用于各种句式。如： She can play a few simple tunes on the piano. 她会在钢琴上弹一些简单的调子。
（肯定句） Can you write with your left hand？ 你会用左手写字吗？（疑问句） I cannot promise you anything. 我不能答应你任何事。（否定句） can亦可指将来。
如： We can discuss your paper after lunch. 午饭后我们能讨论你的论文。 如需要强调将来时间时，则可用短语shall/will be able to。
如： I shall be able to earn my own living soon. 我很快就能自立了。 He says he'll be able to be home for Christmas. 他说他能回家过圣诞节。
could是过去式，表示过去。如： I said that I could go. 我说我能去。
Could the boy read before he went to school？ 这男孩上学前能识字吗？ 表示过去的能力也可以用was或were+able。如： I was able to help you yesterday. 我昨天能帮你的。
但could也常可指现在或将来。如： You could phone her, I suppose. 我看你可以给她打电话。
The river could easily overflow, couldn't it？ 河水可能容易泛滥，不是吗？ 如could与动词原形的完成式连用，则指过去未实现的动作。如： She could have explained the mystery. 她本能够解释这个秘密的。
（实际上未解释） 2）表可能。如： The moon cannot always be at the full. 月不可能常圆。
If it's raining tomorrow, the sports can take place indoors. 如果明天下雨，运动会就可能在室内举行。 can表可能时可指现在或将来。
如： You can perhaps obtain a dog from the Dogs' Home. 你也许可以从养狗场弄到一条狗。（肯定句） What can he mean？ 他可能是什么意义呢？（疑问句） We can't use the indefinite article with this noun. 我们不可以在这个名词前用不定冠词。
（否定句） 表可能时，could作为过去式，也可以指过去。如： He said he couldn't agree more. 他说他再同意不过了。
could亦可指现在或将来，表虚拟语气。如： It could be my mother. 可能是我母亲。
He could arrive tomorrow. 他可能明天到。 could与完成式连用，则指过去未实现的动作。
如： It could have been seen from here if it had not been so dark. 如果天不那么黑，你可能从这儿望见它的。（实际上已望不见） 3）表允许。
如： You can borrow my bike tomorrow. 明天你可以借用我的自行车。 表这个意义时，can用于疑问句时表要求，用于否定句时表不许。
如： Can you lend me a hand？ 你能帮我一把吗？ This sort of thing can't go on！ 这类事不能再继续了！ could指现在时，仅用于疑问句表更委婉的要求。如： Could I interrupt a moment？ 我可以插句话吗？ could也可以指过去，用在主句为过去式的名词性从句中。
如： Father said I could swim in the river. 爸爸说我可以在河里游泳。 4）表怀疑。
如： Can it be true？ 那会是真的吗？ 表这个意义时，can仅用于一般疑问句，并有感情色彩。 can用于一般式，表现在。
如： Can he really be ill？ 你真的会病吗？ can用于进行式，表将来。如： Can he be making the investigation all alone？ 他会独立进行调查吗？ can用于完成式，表过去。
如： Can she have told a lie？ 她会说谎吗？ can用于完成式或完成进行式时亦可表持续的动作。如： Can she really have been at home all this time？ 她真的会一直在家吗？ Can she have been waiting for us so long？ 她会等我们这么久吗？ could指现在时亦可有这些用法，但暗含着更不确定的意义。
如： Could it be true? Could she be telling lies? Could he have said it? Could he have been at home all this time? Could she have been waiting for us so long? 5)can't表不大可能。如： It can't be true. 那不大可能是真的。
can't会有感情色彩。如： He can't be really ill. 他不大可能真的病了。
（指现在） She can't be telling lies. 她不大可能说谎。（指现在） He can't have said it. 他不大可能说这种话。
（指过去） She can't have been at home all this time. 她不大可能一直在家。（指过去） She can't have been waiting for us so long. 她不大可能等我们这么久。
（指过去） could。
