so that和in order to的区别是什么?
区别如下：1、意思不同。so that：因此。in order to：为了。2、用法不同。so that：that用作指示代词的意思是“那，那个”。可指前面提到的那件事，也可指在空间或时间上较另一事物远的事物或人，还可指要表明的或要提及的事物、想法等。in order to：order作“次序，顺序”“治安，秩序”“整齐，有条理”解时，是不可数名词。作“订购，订货”“命令，嘱咐”“汇票，汇单”解时，是可数名词。3、来源不同。so that：that直接源自原始日耳曼语的that；最初源自原始印欧语的tod或tad，意为那。in order to：13世纪初期进入英语，直接源自古法语的ordre；最初源自拉丁语的ordinem，意为序列
in order to的用法是什么，和so as to的用法有何不同？
in order to的用法：in order to意为“为了……”，表示目的；在用法和意义上相当于so as to结构，但是in order to结构可以用于句首、句中，而so as to多用于句中。其否定式分别为：in order not to和so as not to。in order to和so as to在句中表示目的时，常可以转化成in order that或so that引导的目的状语从句。如：We should work hard in order to / so as to pass the exam.→We should work hard in order that / so that we can pass the exam.为了能通过考试，我们应该努力学习。“in order that”和“in order to”的区别in order that后面接句子；in order to后面直接接动词原形。例句： 1、In order to earn enough money, he worked late into the night. 为了赚到足够的钱，他工作到深夜。2、In order that training should be effective it must be planned systematically.为使培训有成效，必须有系统的计划。
so that, so as to, in order to 怎么区别？分别有什么用法？
so that 后面跟目的状语从句。in order to和 so as to后面跟动词原形，in order to可以放在句首但 so as to不行。You must speak louder so that /in order that you can be heard by all.The doctors gave her a general checkup so as to/ in order to find out the cause of her illness.The boy is so young that he can't go to school.属于目的状语从句:从句部分是用以补充说明主句中谓语动词发生的目的的状语从句。举例：Say it louder(so)that everyone can hear you.大声说，以便大家都能听到你的声音。So that在目的状语从句中可表示"为了"的意思;在结果状语从句中表示结果。目的状语从句:从句部分是用以补充说明主句中谓语动词发生的目的的状语从句。表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导;目的状语从句的谓语常含有may, might, can, could, should, will, would等情态动词。一些用法：1) so … that…/ such ….that该句式中重要考查的是so和such的区别。应注意以下可能出现的结构:so nice a boy that…such a nice boy that…so beautiful/diligent/carefully … that…such (fine weather/great improvement) that…2) so thatShe worked hard so that everything would be ready by 5 o'clock.她努力工作，以便在五点前是一切都就绪。She looked down so that she should not see his eyes.她垂下目光，使她看不到他的眼睛。Everyone lend a hand, so that the sowing was done in time.该句式中主要考查so that 与其它短语的区别，如:由于so that也可以引导目的状语从句，同学们应特别注意从句中时态的运用。3) so much so that该结构用于形容词或副词之后，表示"到如此程度以致于"。如:He was very weak, so much so that he could not walk.I long to visit Beijing, so much so that I dream about it every night.4) 注意结果状语从句与too….to..enough to…, so… as to结构的不同。5)in order(that)"以便" to the end that "为……起见，以便"
to,so as to,in order to,so that,in order that的区别
to,so as to,in order to,so that,in order that 的主要区别：1、to,in order to,in order that 既可用在开头,也可用在句中。so as to ，so that 只能用于句中。 2、to，so as to，in order to 后面接动词原形，in orde that，so that 后面接从句。具体用法： 1、to 也可以表示“为了”，to 不定式做目的状语，后接动词原形，表示目的。 And to create it, you have to create it for yourself. 2、so as to 表示目的是...，后面接动词原形，表示结果，和 in order to 的意思相同，但只能用在句中。I got up early in the morning so as to catch the first bus.3、in order to 意思是“为了”，约等于to，但比to的目的性更强，后接动词原形 。用来表目的,它所引导的是目的状语，采用in order to+动词原形的形式。既可用在开头,也可用在句中。I got up early in the morning in order to catch the first bus. （用于句中）In order to catch the first bus,he got up early in the morning.（用于句首）在一般情况下，to、in order to、so as to可以互换，但so as to不能用于句首，而in order to既可以位于句首，也可位于句中。4、so that 是以至于的意思，有时可与in order that 互换，多用于非正式语体，so that后面接从句。1）so that用来表示目的，在非正式语体中,so可以代替so that,引出目的状语从句. 例如：He is going to the lecture early so (that) he will get a good seat.2）so that表结果.so是so that 的省略形式,引导结果状语从句,主要用在口语中. You must speak louder so that you can be heard by all.5、in order that用于相当正式的语体中,表示经过精心策划的目的,有时可与so that互换。1）引导的状语从句有时也采用现在虚拟式。 They removed the prisoner in order that he not disturb the procceedings any further. 在正式语体中,in order that,上句中的he not disturb也可以用he should not disturb来替换。2）in order that从句中可以使用can,could,may,might,should,would等情态动词. You must speak louder in order that you can be heard by all.so that 约等于in order that for 加在不定式前面，不定式的发出者为for后面的名词 。在一般情况下，so that前后两句主语不同，而in order that前后句主语一致。
so that, so as to, in order to 怎么区别？分别有什么用法？
in order to+动词原形和so as to+动词原形 都可以放在句中。 She got up early in order to / so as to catch the first bus. 她早早起了床以便赶上头班车 。 The doctors gave her a general checkup so as to/ in order to find out the cause of her illness. 医生给她做了全身检查， 以便找出她的病因。 in order to 可以放在句首，而so as to 则不可。 In order to win the watch , they practiced hard. 为了赢得比赛，他们刻苦训练。 In order to get good results, we ought to do our best to study the lessons. 为了获得好成绩， 我们应尽最大努力学好课程。 2.so that 和 in order that 意思相同 “目的是 以便”引导目的状语从句
You must speak louder so that /in order that you can be heard by all. 你必须大点声，别人就能听见了。
3. so…that 和 such…that 如此..以至于..
结果状语从句常由so…that 或 such…that引导。so…that与such…that之间可以转换。例如：
The boy is so young that he can't go to school. 这男孩年龄太小，不能上学。
He is such a young boy that he can't go to school
so as to与so... as to的区别
虽然so as to与so... as to在形式上差不多, 而且后面都接动词原形, 但它们表示的意思和在句中的作用却不同: 前者表示“为的是; 是为了; 以便”的意思, 与其后的动词原形一起作目的状语, 用来强调目的; 后者表示“那么地……, 以至……”的意思, so后面接形容词或副词, 在句中as to和其后的动词原形一起作结果状语。例如:
Sometimes my friend goes to the library so as to borrow books. 我朋友有时去图书馆为的是借书。
Tomorrow my father will go to Beijing so as to see his old friend. 我父亲明天去北京是为了看望他的老朋友。
The girl was so excited as to shout herself hoarse. 那个女孩兴奋得喊哑了嗓子。（或译为: 那个女孩是那么地兴奋, 以至于嗓子都喊哑了。）
He was so tired as to be unable to walk. （＝He was too tired to walk. ）他累得走不动了。（或译为“他是那么累, 以至于不能走路了。）

The little boy ran so fastas to falldown. 那个小男孩跑得太快, 跌倒了。（或译为: 那个小男孩跑得那么地快, 以至于跌倒了。）
Yesterday morning I got up so late as to be late for school. 昨天早晨我起得那么晚, 上学都迟到了。
另外, 还有三点需注意:
1. 如果是表示否定目的, 则要在“to”前加否定词not, 即要用“so as not to”的形式。例如:
Let''''s hurry up so as notto be late for class. 我们快点走吧, 以免上课迟到。
Next week I am going to Beijing so as not to attend a meeting. 我下星期去北京不是为了开会。
2. so... that 和so... as to虽然表示的意思几乎是一样的, 而且两个so后面都是接形容词或副词, 但它们所在的句子种类不同: 前者所在句子是带结果状语从句的复合句, 而后者所在句子是简单句。当复合句的主句和从句的主语相同, 而且从句又是表示肯定意思时, 两者可互换使用。例如:
Just now they were so happy that they jumped. 可改为: Just now they were so happy as to jump. 刚才他们高兴得跳了起来。
3. in order to是so as to的同义词组, 两者一般可互换使用。但是, 当特别强调目的, 且把目的状语放在句首时, 只用in order to。例如:
In order to realize our dreams earlier, each of us must study even harder. 为了早日实现我们的理想, 我们每个人都必须更加努力地学习。
so as to与such as to有什么区别
so as to和such as to都可以表示结果，区别如下：
so as to的so为副词，后面可以接形容词、副词或动词，as to后面是动词原形，如：
The building is so tall as to resemble a tower.
He was so angry as not to be able to speak.
such as to的such为形容词，后面可以接名词，也可以放在be动词的后面，as to后面也是动词原形，如：
His anger was such as not to be able to speak.
The height of the building is such as to resemble a tower.
