6、r up 天空放晴clear away 消除endless plainhopelesshelplesstreeless carelessuselessplain n 平原adj 普通的a plain girlCan 和be able to 1.can和could 我们已经讲过can和could都可以表示“请求允许做某事”，can比较生硬，用于和自己同等的人或是熟悉的朋友。而could相对比较客气，显得更加礼貌，同时也反映出请求者的犹豫不决。Can I use your telephone?Could I use your telephone?2.can和be able to can和be ab
7、le to都可以解释为“能够、可以”。可以表示“有能力来做某事、有时间来做某事，有办法来完成某事”等等。我们在区别他们时，需要注意的a.在表示现在或过去的智力、体力、技能等方面的“能力”时,can、could常可与 be able to互换。I can swim now.=I am able to swim.我会游泳。b.can表示“能够做某事”，不一定就真的做了。而be able to表示“有能力做某事”。说明是真的尝试过了，做过了这件事情。所以赶拍胸脯说自己有这个能力。比如：I can swim 300 meters now and last year I was able to swim
8、 100 meters.我现在能够游300米，去年我可以游100米的。这句话中，第一部分“I can swim 300 meters now”，表示“我现在能够游300米”只是说说而已，并不说明已经游过了。而后面部分“last year I was able to swim 100 meters”，表示我去年的确是游过了，可以游100米的。c.be able to 有比 can 更多的形式。从时态上来说：can做为情态动词，只有现在时和过去时。而be able to则有比can更多的形式，除了现在时和过去时，还有将来时和完成时。He will come if he can.=He will c
9、ome if he is able to.I can see you tomorrow.Ill be able to see you tomorrow.（将来时使用will be able to结构）I couldnt understand him.=I wasnt able to understand him.（过去时使用was/were able to结构）He said he could see me next week.=He said he would be able to see me next week.(过去将来时使用would be able to结构)请大家注意，如果要体现
10、将来时和完成时，那只能用be able to。因为can作为情态动词只有现在时和过去时。综合上面的几点，我们简单总结一下：can和be able to在表示个人能力时，一般可以进行互换。Can表示“能够做某事”，是未经尝试过的能力；而be able to则多表示“有能力做某事”多为已经过事实验证的。Can用于现在时和过去时；而be able to由于有个be动词，所以它时态的使用就灵活了许多，将来时、完成时等时态用be able to表示则非常清晰方便。下面最后一点：当我们要表示一个动作已经成功的在过去完成的时候，我们必须使用was able to，而不能使用could。听录音，然后回答以下问
