语法是使用语言的规则，因此，要掌握好英语必须学好英语语法。我们学习语法的目的并不是为了知道一些语法术语。学习语法的主要目的是为了掌握语言。
学习语法要注意语法形式，也就是说需要注意形式变化，同时还需要注意各种不同的形式在什么情况下使用。例如，学习一般现在时的时候首先应该注意在第三人称单数的情况下，谓语动词加-S或ES。
同时还学要注意它的主要用法，也就是说在什么情况下使用一般现在时。学习英语语法应当避免专牛角尖。例如，分析句子是为了理解。如果已经理解的句子就没有必要再去分析每个词到底是什么成分。
No one 与None 的用法
1.no one 指人，动词用单数，none 可用于指人或物。no one= not any one,意为“连一个也不”，比none语气强。none 通常与of 短语连用作主语，如果后面接复数名词，谓语动词可以用单数也可以用复数; 如果接不可数名词，谓语动词要用单数。
例如：
None of us are/is wrong.
None of us has/have ever been abroad.
There was no one to look after the child.
None of this money is his.
2.要注意none 的几个习惯搭配：
(1) none other than 不外乎是，正是，就是
The man was none other than my husband.
(2) none＋the+形容词比较级+(for)…仍然，依然
It was none the better for the remedy.
For all his years, he is none the less vigorous and active.
(3) none but 只有
None but the aged and the sick stayed at home.
used to 与 would 的用法
used to 和would 都可以表示过去时间经常的习惯动作，但是它们的含义和用法不尽相同。
1.would 是以一种回忆往事的心情来描述过去经常重复的习惯动作，而used to 则强调过去与现在的对比，并且表示较远，目前不复存在的习惯。例如：
Every evening she would teach us to read and write.
My brother used to be a worker, but now he is a college teacher.
He will not have the money to spend on books as he used to.
2.would 只能和表示动作的动词连用，而used to 既能和动作动词连用，也能和状态的动词连用。例如：
There used to be a temple there.
He would spend all he earned on books.
would 和will 的形式和用法
1.表示主语的强烈意志或主张，意为“无论如何总是要”。will 表示主语现在或经常性的情况，would 表示主语过去的情况。
My children will not listen to me.
His father was angry because he would not obey him.
That window would not open.
The manager would have his own way.
2.will 作情态动词时，表示将来的意志，意愿。
I will send photos to you soon..
I will never talk about again.
3.will表示命令，请求，规劝等。
Will you pass me the salt, please?
Go and get the newspaper, will you?
Won’t you sit down.
4.would 表示过去的习惯，习性，倾向等。
When I was a child, I would go skating.
We would stay up all night talking about our future.
表语从句和同位语从句中的虚拟语气
在表示建议，命令，主张，目的，愿望等名词后面的表语从句和同位语从句中谓语动词要求用虚拟语气，其形式为（should）+动词原形。例如：
He gave orders that the guests (should) be hospitably entertained.
The proposal that he be invited was rejected.
Her suggestion is that we (should) give up the plan.
His proposal is that we (should) get rid of the bad habits.
常用的这样的名词有：
resolution, pray, decision, motion, suggestion, preference, proposal, advice, recommendation, desire, demand, requirement, order, necessity, request, idea.
