21. The job was hard, which made me so tired that I almost quit half way.
这份工作太辛苦，差点使我半途而废。
解析：
(1)so… that…引导结果状语从句，常和too…to…结构互换。
The job was hard, boring and seemed endless, which made me so tired that I almost quit half way.
这份工作太辛苦、太无聊，而且没完没了，这使我非常累，差点半途而废。
My sister is too young to go to school. 我妹妹是如此的小以至于不能去上学。
=My sister is so young that she can"t go to school.
so that 引导目的状语从句（常常与情态动词连用），意为“以便;为了”，相当于in order to/so as to.常放于句中，但是in order to常放于句首或句中，so as to常放于句末。
eg: Xiao Hua studies hard so that she can get a good grade in last examination.
肖华学习努力是为了在期末考试中取一个好成绩。
My sister made a model plane so that she could help with her friend studying the science last night.
昨天晚上我妹妹制作了一个飞机模型以便她能帮助她的朋友学习科学。
In order to watch the soccer game, I stayed up late last Saturday. 为了观看足球比赛，上周六我熬夜了。
My mother often gets up early in order to make breakfast for me. 我妈妈通常起床很早以便给我做早餐。
She buys a new dress so as to join Lisa"s birthday party. 她买了一条新裙子是为了参加丽莎的生日派对。
其实：so that也可以引导目的状语从句：
He hurriedto the station so that he could catch the early bus.=
He got to the station hurriedly so that he could catch the early bus.
他匆匆忙忙赶到车站，为的是能搭上了早班车。
so that也可以引导结果状语从句：
He hurriedto the station so that he caught the early bus.=
He got to the station so hurriedly that he caught the early bus.
他匆匆忙忙赶到车站，结果搭上了早班车。
特别注意考点：在“so +adv/adj+that 结果状语从句”中常常把so +adv/adj放在句首，并将谓语动词倒装来表示强底：
So hard did the boy study that he passed the exam.
这个男孩学习如此努力，以至于他通过了考试。
So clever is the boy that he can answer the question.
这个男孩很聪明，他能回答这个问题。

请比较：
They are such children that they cannot do the work well.
这些孩子太小，做不好这项工作。
I have so little money that I can’t buy the car.
我的钱太少买不起这部小汽车。
说明：little表示“小”时，用such……that; little表示“少”时，用so……that
另外：
so+many/few+n+that
so+much/little+不可数名词+ that
当such……that之间用“不定冠词+形容词+单数名词”时，可以用so……that结构替换，但是，此时so和形容词连用，接着是不定冠词和单数名词连用，再that结构：
That was such an important party that I had to take part in it.=
That was so important a party that I had to take part in it.
那是一个如此重要的会议，以至于我不得不参会。
(2)能够增加句子层次的高级连词还有：
Not only …but also…、Because…、because of…、As long as…、so long as…有关这些句型前面文章多有论述，敬请查看，不在赘述。
