本周继续分享第91课0755到79000重点句型或语法。先读课文：

一.原文

Lesson 91 Three men in a basket

A pilot noticed a balloon which seemed to be making for a Royal Air Force Station nearby. He informed the station at once, but no one there was able to explain the mystery. The officer in the control tower was very angry when he heard the news, because balloons can be a great danger to aircraft. He said that someone might be spying on the station and the pilot was ordered to keep track of the strange object. The pilot managed to circle the balloon for some time. He could make out three men in a basket under it and one of them was holding a pair of binoculars. When the balloon was over the station, the pilot saw one of the men taking photographs. Soon afterwards, the balloon began to descend and it landed near an airfield. The police were called in, but they could not arrest anyone, for the basket contained two Members of Parliament and the Commanding Officer of the station! As the Commanding Officer explained later, one half of the station did not know what the other half was doing!

第二，关键句型或语法

这节课主要是复习在第19课、第43课和第67课中学到的动词can和may、can和able to and manage to的用法差异。

第十九课

这节课主要讲can和may的区别。两者都可以表示允许，但may更委婉。比如：

Can I go home now?

May I go home now?

Can't常用作对may的否定回答，如：

May I open the door?

No, you can't.

另外，本课中还有一个may不妨的用法，表示“不妨；或者.算了”，比如：

I may as well take this umbrella.

Maybe是May的过去式，但powery常用来表达比过去更委婉的语气。

第四十三课

这节课重点讲了能和能够做的区别。Can的意思是“会做某事”，而able to do的意思是“会做某事(经过努力)；能够”。比如：

He can drive a car. He can drive a car.

He can drive a car. He can learn to drive.

He was able to leave Paris before the war broke out.

他得以在战争爆发前离开巴黎。

第六十七课

这一课着重于能和能够做和设法做之间的区别。其中，设法做意味着“设法成功地做某事”，这类似于能够做。比如：

He managed to arrive in London at last.

他终于设法到达了伦敦。

第三，一课一问

根据本节课的复习内容，让我们根据提示练习并将下列句子翻译成英语。

杰森会开飞机。(可以)

三天后我回到了莫斯科。(能够)

她设法通过了驾驶执照开始。(设法)

你不妨接受她的建议。(不妨)
