1、 名词的单复数
规则变化+s/es、不规则变化（mouse-mice）、单复数同形、同一词在不同意义下有可能可数有可能不可数
2、 名词所有格
‘s（表示有生命：Lily’s desk）、of所有格（表示无生命the window of the room）
3、 名词修饰语
只修饰可数名词（each、every、a great many）、只修饰不可数名词（little、a little、 a large amount of）、都可以修饰（some、a lot of、plenty of）
4、不定冠词（a/an单数不特指）；定冠词（the/this/that/these/those表特定）
5、such的用法
such作限定词和all,no,any,some,other,anther等词连用时，such放后面。
如果such修饰单数可数名词，且与不定冠词连用时需置于其前；such前有no时不用冠词。

在肯定句中表示与上文相同的情况，如：So do I.

8、 many修饰或替代可数名词，much修饰或替代不可数名词
many a 许多（谓语动词用单数）
a good/great many很多
as many as/as much as一样多、差不多
9、 little几乎没有，修饰不可数名词
a little有一点，修饰不可数名词
few几乎没有，修饰可数名词
a few有一点，修饰可数名词

12、介词短语重点
except for除了
in place of代替
on behalf of代表
but for要不是
in front of在…前面

14、易混淆的介词短语
in all总共
after all毕竟

15、序数词前一定要加定冠词the，改错常考，序数词与基数词连用时，序数词放在前面，如the first one。
16、will和would的用法（常考）

17、虚拟语气
18、一般现在时表将来的2种情况：
拟定或安排好的事情、一定要发生的动作：The train arrives at 10.
在时间状语从句、条件状语从句、让步状语从句中一般现在时表将来

21、常用句型：

It is adj. of sb. to do sth.（形容词评价某人）
22、经常接疑问词+不定式的动词：learn,ask,discuss,explain,know,remember,forget,understand,think,consider,decide.
如 I have to learn how to study English.
23、主谓一致
the number of+复数名词作主语时，谓语动词用单数
a number of+复数名词时，谓语动词用复数
someplenty ofa lot of，谓语动词根据所修饰的词而定
a quantity of谓语动词用单数；large quantities of谓语动词用复数

either…or…/neither…nor…/not only…but also…谓语动词和靠近的主语一致（常考）

常跟同位语从句的名词或短语（常考）：belief/doubt/hope/report/word/opinion/idea…使用举例：We have some doubt whether they can complete the task on time.
26、直接引语和间接引语
变间接引语要向前推一个时态！例：
He said, ”I am sorry.”
He said that he was sorry.

He is the man who lives next door.
I have many friends to whom I am going to send postcards.
28、定语从句that/which的用法，通常可以互换，但下列情况必须用that（改错常考）：
先行词是all,much,few,little,something等不定代词时
先行词有the only,the same,the very修饰时
主句是以which开头的特殊疑问句时
先行词既有物又有人时
先行词是序数词、形容词最高级时
29、as和which用法辨析，引导非限定性定语从句
as的先行词只能是句子，which的先行词可以是词。
30、表示一…就的引导词
as soon as/immediately/instantly/the moment/no sooner than/hardly
31、no sooner与hardly在句首时，要求句子倒装。
32、so that 连用引导目的/结果状语从句
so adj./adv. /many/few+that：There is so little time that…
such adj.+名词+that：Kathy is such a lovely girl that…
