代词it、one、that的用法与区别
One泛指，指代前面提到的那类人或物，用于指代可数名词，相当于a+名词单数，其复数形式ones前一般要有定语，否则就要用some.
That(those复数)即可指代不可数名词，表特指，相当于the+名词，后面经常与介词修饰语连用。 It指代上文出现的名词，表示同类同物，另外还可表示时间、距离、天气、还可指代人称代词，表示性别身份不明，可作形式主语，形式宾语，引导强调句式以及一些固定搭配，如：get it, catch it, make it.
例如：① I have lost my watch. I think I must buy one.我丢了只表，我想我必须再买一只。(代指上文指到的同类事物，但不指同一个)
② Where is my pen? Have you seen it?
我的钢笔不知弄到哪去了，你见了吗?(代指上文提到的同一事物) ③ The land of China is larger than that of America.
④ Tome has a red pen and a blue one (或two blue ones)

结果状语从句
引导词：so...that(如此。。。以至于。。。)，such...that(如此。。。以至于。。。)，so that(结果是)，with the result that(所以，结果是)
注意：(1)so...that与such...that的区别
So+形容词such+a/an+形容词+单数名词
So+形容词+a/an+单数名词such+形容词+复数名词
So+副词such+形容词+不可数名词
So many/few+复数名词
So much/little+不可数名词
(2)so that引导的目的状语从句与so that 引导的结果状语从句
目的状语从句一般使用情态动词，结果状语从句一般不使用情态动词;
结果状语从句常常用逗号与主句分开。
(3)so...that与so...as;such...that与such...as
So...that/such...that为结果状语从句;so...as/such...as为定语从句。
条件状语从句
引导词：if(如果)，unless(除非)，if only(只要，但愿)，only if(只有)，in case(万一)，suppose/supposing(that)
(假设)，provided/providing(that)(只要，假若)，on condition that(要是，在。。。条件下)，so/as long as(只要)，(let's/let us)say(假设)
方式状语从句
引导词：as(像。。。一样，正如。。。)，as if/as though(好像，宛如)
注意：1、固定句型A is to B what C is to D.意为“A对B而言正如C对D一样”。
2、as if, as though引导的从句若与事实相反，用虚拟语气;若与事实相符，不用虚拟语气。
让步状语从句
引导词：though/although/as(虽然，尽管)，even if/though(即使，尽管)，whether/no matter whether...or(not)
(不管。。。是否，不管是。。。还是)wh-ever/no matter wh-(无论。。。)
注意：(1)though,although,as的区别
A、Though,although的主句中可以用yet, still, nevertheless,但不可使用but。
B、though引导的从句可以倒装，也可以不倒装;as引导的从句必须倒装;although引导的从句不能倒装。
其结构为：形容词/分词/副词/动词原形/名词(无冠词)+as/though+主语+谓语……
(2)though可用作副词，放在句末，意为“不过，但是”。Although无此用法。
(3)某些短语也引导让步的从句或短语，意为“尽管”，如：in spite of the fact that, despite the fact that, regardless of(the fact that)
