第七十五课 SOS 求救信号

1.When a light passenger plane flew off course some time ago, it crashed in the mountains and its pilot was killed.
(1)fly off course 偏离航线
off 离开，偏离 course 可以指跑道，航线，比如说，
The boat was blown off course. 那艘船被吹离航线。
(2)crash 碰撞, 坠落, 坠毁 而crash into的意思是“闯入”
大家都知道美国911事件中飞机冲入世贸大厦我们就可以说：
That plane crashed into the world trade building.
(3)pilot 除了指飞行员，还可以指舵手
When Mark Twain was young, he was a pilot on the Mississippi River.
马克吐温年轻的时候曾经是密西西比河上的一位舵手。

2....were unhurt.
unhurt 平安无事
un- 否定前缀，比如还有 uncomfortable 不舒服 unfair 不公平

3.Snow lay thick on the ground.地上积着厚厚的雪。
lie表示“处于某种状态”时，后面常跟形容词或分词：
When I saw her yesterday, she lay ill in bed.
昨天我见到她时，她正卧病在床。

4.When it grew dark, she turned a suitcase into a bed and put the children inside it, covering them with all the clothes she could find.
(1)When it grew dark做时间状语，真正的主句是she turned a suitcase into a bed and put the children inside it，而后面的covering them with all the clothes she could find属于分词作状语。
(2)grow+adj.的意思是变得...同样，还有下面一些词
get old; turn green; go bad; come true; feel bad 这些都是动词直接+形容词,前面动词的意思是变得。比如这个句子：
When the spring comes, the trees turn green.
类似的例子参考p352.

5.The woman kept as near as she could to the children…
keep表示“保持某种状态”。 as…as one can/could和 as…as possible同义，都表示“尽可能……”：
He got through as much food as he could and set out. 或者
He got through as much food as possible and set out.
他吃了尽可能多的食物，然后出发了。

6.She stamped out the letters‘SoS’ in the snow.
stamp out 可以作为一个短语去理解，意思是扑灭，踩灭。比如，
He stamped out the fire.他把火踩灭了。
而文中的out应该理解为“出现，显露”
那么句子就应该翻译为，他踩出了SoS这三个字母。
类似短语write out 写下，写出 write out a list of names

7.It was not long before a helicopter arrived on the scene to rescue the survivors of the plane crash.
(1)It was not long before…为固定句型，表示“不久就……”比如
It was not long before he learnt the news.
或者这个句型还可以用在将来时里面，比如
It will not long before the truth comes out.
不久真相就会出来的。
(2)arrive on(upon) the scene 到达出事现场,这也是一个常用短语。而arrive表示到达的时候可以用arrive in/arrive at.
他们的区别是in后面界的是大地方，比如一个城市；而 at后面是小地方，比如一个村庄。

重点短语/句型：

fly off course 飞离航线
crash into 撞入
turn... into... 变成
cover...with... 用...盖
as...as one could 尽可能
stamp out 踩出
it is not long before... 不久以后
arrive upon the scene 到达现场
