18、h. / seem to be + adj. / seem + adj. / It seems that rise, raiseby in sight / out of sightwithout difficulty,Grammar,Can 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? 我能用一下你的电话吗？ Could I use your telephone?
19、 我能用一下您的电话吗？ 2.can和be able to can和be able 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,Grammar,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
20、swim 300 meters now and last year I was able to swim 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。,Grammar,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

22、e 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。,Grammar,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
