教学内容
They organized a lot of activities for me in my spare time so that I wouldn’t miss home or feel lonely.
Mary lent me this book so that I could read about Chinese history.
I exercise every morning so that I will stay healthy.
We can use so that + a clause to talk about purpose. This is called an adverbial clause of purpose.
We often use can, may or will (for the present) or could, might or would (for the past) in an adverbial clause of purpose.
Pay attention to the following underlined and circled parts.
目的状语从句用来说明事情发生的目的，通常用so that来引导。
so that引导的目的状语从句中常常含can，may，will或should等情态动词；在谈论过去的句子里，so that 后面的动词通常与could，might，would或should连用。
e.g. You must speak louder so that you can be heard by all.
I got up early so that I could catch the first bus.
目的状语从句
当从句的主语与主句的主语一致时，so that引导的目的状语从句可以改写成含in order to或so as to的简单句。注意so as to一般不可放在句首。
We practise every day so that we can win the match.
We practise every day in order to win the match.
In order to win the match, we practise every day.
We practise every day so as to win the match.
so & so that
so 连接并列句 表示逻辑结果 前面可加逗号与前半句隔开
so that 引导目的状语从句 表示目的 前面不可以加逗号
It was raining, so I took an umbrella.
I took an umbrella so that I would not get wet.
so that引导的目的状语从句与结果状语从句的区别
目的状语从句中一般含有情态动词can/could，may/might，will/would，should，而结果状语从句中则没有。
I ran as fast as possible so that I could catch that bus. (目的)
I ran as fast as possible so that I caught that bus. (结果)

汉译英。
他们在我空闲的时候给我安排了很多活动，这样我就不会想家，也不会觉得孤单了。
状语从句在句子中作状语。状语从句可以表示条件、时间、比较、原因、让步、结果和目的等。
状语从句
条件状语从句常用的连接词主要有if, unless, as long as等。如：
If I am not busy tomorrow, I will play football with you.
You won’t pass the exam unless you work hard.
As long as you take my advice, you will do very well.
一、条件状语从句
注意：
通常情况下， 由if, unless或as long as引导的条件状语从句用一般现在时，主句谓语动词用一般将来时。
在叙述自然规律时常用if从句表示前提，没有时间性，这时主句谓语动词也用一般现在时。
时间状语从句常用的连接词主要有：
when, while和as 如：
When he came in, I was listening to the radio.
As I was walking down the street, I met her.
While/As I was watching TV, my mum was cooking in the kitchen.
二、时间状语从句
注意：
表示“当……时候”的意思时，如果主句和从句的动作同时发生且都是进行时态，只能用while或as。在其他情况下，when, while和as可以通用。
before, after, since和until (till) 如：
He usually drinks a cup of tea before he goes to work.
My mother goes to work after she has breakfast.
I have not seen Jim since I graduated from high school.
I will wait here until (till) you finish your job.
as soon as 如：
As soon as she finishes her homework, she will go to play tennis.
比较状语从句常用的连接词有as … as和(not) so … as等。如：
Mrs Smith is as friendly as Mr Smith (is).
Jane does not sing so well as her elder sister (does).
三、比较状语从句
结果状语从句常用的连接词有so … that和such … that等。如：
He ran so fast that we couldn’t keep up with him.
She is such a nice teacher that all of us love her.
四、结果状语从句
原因状语从句常用的连接词有because, as和since等。如：
Tom was late for school this morning because he didn’t catch the early bus.
I can’t go to Beijing on business as my mother is ill.
Since all of us agree about this plan, we will carry it out next week.
五、原因状语从句
注意：在这三个连接词中，because语气最强，since次之，as最弱；because, as, since引导的从句可在主句前面或后面。此外，它们不能与so出现在同一句中。
让步状语从句常用的连接词有although, though等。如：
Although/Though I gave him some advice, he didn’t take it.
Although/Though he worked hard, he still failed the Maths exam.
六、让步状语从句
注意：although 和though的用法相近，都不可与but连用，但可与still, yet等连用。
目的状语从句常用的连接词有so that, in order that等。如：
Cherry was walking quickly so that/ in order that she could arrive at the cinema in time.
七、目的状语从句
注意：通常情况下，so that相当于in order that。
