课文讲解
Text
In 1929, three years after his flight over the North Pole, the American explorer, R.E. Byrd, successfully flew over the South Pole for the first time. 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. At one point, it seemed certain that their plane would crash. It could only get over the mountains if it rose to 10,000 feet. Byrd at once ordered his men to throw out two heavy food sacks. The plane was then able to rise and it cleared the mountains by 400 feet. Byrd now knew that he would be able to reach the South Pole which was 300 miles away, for there were no more mountains in sight. The aircraft was able to fly over the endless white plains without difficulty.
参考译文
美国探险家 R.E. 伯德在飞越北极3年之后，于1929年第一次飞越了南极。
虽然开始时伯德和他的助手们拍下了飞机下面连绵群山的大量照片，但他们很快就陷入了困境。
在有个地方，飞机似乎肯定要坠毁了。
只有在飞至10,000英尺的高度时，它才能飞过这些山头。
伯德马上命令他的助手们把两个沉重的食物袋扔掉，于是飞机可以上升了，它在离山头400英尺的高度飞越了过去。
伯德这时知道他能够顺利飞抵300英里以外的南极了，因为前面再没有山了。
飞机可以毫无困难地飞过这片茫茫无际的白色原野！

关键句型
Key structures
can / be able to
1．can只有现在是和过去时，can-could，此外could有时并不强调过去时而表请求，更加礼貌，客气。be able to可用于各种时态。
Can I use your telephone
Could I use your telephone
He‘ll come if he can．
He'll come if he is able to.
I can see you tomorrow．
I'II be able to see you tomorrow.
I couldn‘t understand him．
I wasn't able to understand him.
He said he could see me next week.他
He said he would be able to see me next week.
2．当我们要表明一个动作已经成功地完成的时候，我们必须用was/were able to， 不能用could.
He was able to go to London yesterday and he enjoyed himself very much.
他昨天去了伦敦，而且玩得非常高兴。
He was able to leave Europe before the war began.
他在战争开始之前就己经离开了欧洲。
情态助动词can/could用于表示请求别人允许或答复时的情况:
Can/Could I borrow your pen
can有时可以表示可能性：
I can have lunch with you tomorrow if you like.
在表示天生的或学到的能力时，can/could可用于现在时和过去时，can/could与be able to通常可以互换.
I could drive a car by the time I was sixteen.
I tried again and found I could/was able to swim.
表示将来的“能力”时，则用will be able to：
Can Jane swim yet
No, but she’ll be able to swim in a few months’ time.
在谈到说话时正在发生的事时，一般不用be able to：
Look! I can stand on my head.
在表示成功地完成某一具体动作时，通常不用could，而用be able to；如果表示某一动作没有取得成功， 则可用couldn’t：
It’s pity he couldn’t visit Mary.
Oh, didn’t you know He was able to visit her after all.
He was able to leave Europe before the war began.
他在战争开始之前得以离开欧洲。
He was able to go to London yesterday and he enjoyed himself very much.
在问及过去某一具体活动时可用could，但回答是肯定的时候则不能：
Could he borrow a car
Yes, he was able to borrow a car after all.
/No, he couldn’t.
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。
