語法是使用語言的規(guī)則，因此，要掌握好英語必須學好英語語法。我們學習語法的目的并不是為了知道一些語法術語。學習語法的主要目的是為了掌握語言。
　　學習語法要注意語法形式，也就是說需要注意形式變化，同時還需要注意各種不同的形式在什么情況下使用。例如，學習一般現(xiàn)在時的時候首先應該注意在第三人稱單數(shù)的情況下，謂語動詞加-S或ES。
　　同時還學要注意它的主要用法，也就是說在什么情況下使用一般現(xiàn)在時。學習英語語法應當避免專牛角尖。例如，分析句子是為了理解。如果已經(jīng)理解的句子就沒有必要再去分析每個詞到底是什么成分。
　　　　　　　　　No one 與None 的用法
1.no one 指人，動詞用單數(shù)，none 可用于指人或物。no one= not any one,意為“連一個也不”，比none語氣強。none 通常與of 短語連用作主語，如果后面接復數(shù)名詞，謂語動詞可以用單數(shù)也可以用復數(shù); 如果接不可數(shù)名詞，謂語動詞要用單數(shù)。
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 的幾個習慣搭配：
(1) none other than　　 不外乎是，正是，就是
The man was none other than my husband.
(2) none＋the+形容詞比較級+(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 與 would 的用法
　　used to 和would 都可以表示過去時間經(jīng)常的習慣動作，但是它們的含義和用法不盡相同。
1.would 是以一種回憶往事的心情來描述過去經(jīng)常重復的習慣動作，而used to 則強調(diào)過去與現(xiàn)在的對比，并且表示較遠，目前不復存在的習慣。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 只能和表示動作的動詞連用，而used to 既能和動作動詞連用，也能和狀態(tài)的動詞連用。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.表示主語的強烈意志或主張，意為“無論如何總是要”。will 表示主語現(xiàn)在或經(jīng)常性的情況，would 表示主語過去的情況。
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 作情態(tài)動詞時，表示將來的意志，意愿。
I will send photos to you soon..
I will never talk about again.
3.will表示命令，請求，規(guī)勸等。
Will you pass me the salt, please?
Go and get the newspaper, will you?
Won’t you sit down.
4.would 表示過去的習慣，習性，傾向等。
When I was a child, I would go skating.
We would stay up all night talking about our future.
　　　　　　　　 表語從句和同位語從句中的虛擬語氣
在表示建議，命令，主張，目的，愿望等名詞后面的表語從句和同位語從句中謂語動詞要求用虛擬語氣，其形式為（should）+動詞原形。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.
常用的這樣的名詞有：
resolution, pray, decision, motion, suggestion, preference, proposal, advice, recommendation, desire, demand, requirement, order, necessity, request, idea.
