turn on/ turn off/ turn up / turn down

If you feel tired, turn on the radio and listen to songs.
(2)turn off意为“关掉(收音机、电视等电器)”；为“动词+副词”结构，如宾语为it /them的话，应位于该类短语之间。

【重点语法】
动词不定式做目的状语时的用法
To cut down air pollution, we should take the bus or subway instead of driving.
为了减少空气污染，我们应当乘坐公汽或地铁而不是开车。
本句中To cut down air pollution是动词不定式作目的状语。
1. 不定式和不定式短语作目的状语
不定式和不定式短语作目的状语，主要用来修饰动词，表示某一动作或状态的目的。为了使目的意义更加清楚或表示强调意义时，还可以在前面加 in order to 或 so as to。
例如：
I've written it down in order not to forget.He shouted and waved so as to be noticed.
在句子中作谓语动词的状语的不定式或不定式短语，表示的是主语的目的，因此，其逻辑主语通常是句子的主语。
比较：To draw maps properly, you need a special pen.（正）
To draw maps properly, a special pen is needed.（误）
由 in order to 引导的目的状语，既可以置于句尾，也可以置于句首，而由 so as to 引导的目的状语，只能置于句尾，而不能置于句首。
比较：
They started early in order to get there in time.（正）
In order to get there in time, they started early.（正）
They started early so as to get there in time.（正）
So as to get there in time, they started early.（误）
2. 不定式的复合结构作目的状语当不定式或不定式短语有自己的执行者时，要用不定式的复合结构（即在不定式或不定式短语之前加 for + 名词或宾格代词）作状语。
例如：He opened the door for the children to come in.
She fetched several bottles which she placed on the counter for Harry to inspect.
3. 目的状语从句与不定式的转换英语中的目的状语从句，还可以变为不定式或不定式短语作状语，从而使句子在结构上得以简化。可分为两种情况：
（1）当目的状语从句中的主语与主句中的主语相同时，可以直接简化为不定式或不定式短语作状语。
例如：
We'll start early in order that/so that we may arrive in time.
We'll start early in order to/so as to arrive in time.
（2）当目的状语从句中的主语与主句中的主语不相同时，要用动词不定式的复合结构作状语。
例如：
I came early in order that you might read my report before the meeting.
I came early （in order） for you to read my report before the meeting.
【重点句型】
1. Turn off the shower while you are washing your hair. 你洗头发时关掉淋浴器。
(1)turn off意为“关掉”，用于关掉收音机、煤气、自来水等。与其相关的几个短语是：turn on打开；turn down调低；turn up调高。
(2)句中while与when是同义词，引导状语从句，表示时间，意思都是“当(在)……的时候”，但两者之间是有区别的。
1)when既可用于指时间点(从句的谓语动词需用终止性动词)，也可用于指一段时间(从句的谓语动词用延续性动词)，从句与主句中的谓语动词所表示的动作或状态能同时发生，或一先一后发生。如：
①We were talking when the teacher came in.老师进来时，我们正在谈话。
②When he got to the bus stop, the bus had already set off.他到达公交车站时，车已经出发了。
2)while只能用于指一段时间(从句的谓语动词必须是延续性动词)，从句与主句中的谓语动词所表示的动作只能同时发生，不能一先一后发生。如：
While I was reading, my mother was cleaning the room.我在看书时，我妈妈正在打扫房间。
3)when和while还可作并列连词。when表示“在那时”或“这时突然”的意思。如：
I was walking home when I saw a man lying on the side of the road.
我走路回家，正在这时我看到一个男人躺在马路边上。
4)while意为“而；却”，表示对比关系。如：
My sister likes collecting stamps, while I like planting flowers.
我妹妹喜欢集邮，而我喜欢种花。
2. People should stop riding in cars and start riding bikes.
stop的用法 (1)stop为动词，意为“停止，停下”，常构成短语：stop doing sth.意为“停止做某事”；stop to do sth.意为“停下来去做另一件事”。
The students stopped talking when the teacher came in. We are tired. Let’s stop to have a rest.
(2)stop为动词，意为“阻止”。常用作stop sb. (from) doing sth.，意为“阻止某人做某事”。
We can stop people from cutting down trees.
3. I was just in a hurry.
in a hurry意为“匆忙地”，其中hurry为名词。Kate went home in a hurry after class.
拓展：① vt.使赶紧；使匆忙，使急忙。可用作hurry to do sth.，意为“匆忙做某事”。
The girl hurried to catch the train.
②常用短语：hurry off匆匆离去；hurry up匆匆完成；赶快
4.Turn off the lights, Julia
turn off意为“关掉(收音机、电视等电器)”；为“动词+副词”结构，如宾语为it /them的话，应位于该类短语之间。
When you leave the classroom, remember to turn off the lights.
