Byrd, successfully flew over the South Pole for the first time.for the first time 第一次time表示“次,回”,还可以说this time,last time,next time,another time,for the last time我最后一次提醒你,如果你不快点,你就会赶不上火车的。 I remind you for the last time that if you dont hurry, youll miss the train.下次你见到他的时候,把这些照片给他。 Give him these photos next time you see him.,2、Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below, they soon ran into serious trouble.though,其含义是“虽然,尽管”。不与but连用。can.可能性(只用于现在式和过去式)be able to.可能性,成功地做(可用于各种时态)take a photograph of 拍的照片run into trouble = get into trouble 遇到麻烦,陷入困境每次他遇到困难了,他都向父母寻求帮助。Each time he ran into trouble, he asked his parents for help.,3、At one point, it seemed certain that their plane would crash.at one point 在某一地方,在某一时刻(point也指时间上的某一点)他曾一度下决心要当个画家。 At one point, he made up his mind to become a painter.it为形式主语,真正的主语为that引导的从句。似乎可以肯定会议将被推迟。 It now looks certain that the meeting is going to be put off.,4、It could only get over the mountains if it rose to 10,000 feet.rise to 上升至5、The plane was then able to rise and it cleared the mountains by 400 feet.by表示“相差,以之差”的意思我晚了10分钟,没赶上火车。 I missed the train by ten minutes. 他比我小两岁。 He is younger than me by two years.,Key structures,over, on, above can, could, be able to 区别 explorer, explosion at first at/in/on 词组 a great many lie, lay, lain / lay, laid, laid / lie, lied, lied run into seem to do sth. / seem to be + adj. / seem + adj. / It seems that rise, raise by in sight / out of sight without difficulty,Grammar,Can 和be able to 1.can和could can比较生硬,而could相对比较客气, Can I use your telephone? 我能用一下你的电话吗? Could I use your telephone? 我能用一下您的电话吗?,2.can和be able to 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 100 meters.,Grammar,2. 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。 I can see you tomorrow.Ill be able to see you tomorrow.(将来时使用will be able to结构),Grammar,Exercise,1.
