A级常考句型结构：
1 倒装句
如Not until yesterday did I know the truth.
No sooner fedorhad I entered (过去完成时，必须的) the room than the telephone rang （一般过去时，填过去式，必须的）.
So excited was his mother that she couldn’t speak/say a word.
2 强调句
如text是什么意思 It is in Beijing that the agreement was signed.
强调句的一个特点就是去掉it is…that…后原句是完整的句子。上述句子去掉后变成The agreement was signed in Beijing. 只是把要强调的部分放到it is…that中间了。这是强调句与定语从句的区别，定语从句去掉it is…that…不完整，如：It is this place that I like best. 这是定语从句，如去掉it is…that则原句变成This place…I 则不是完整句子成了碎片。
candy什么意思3 虚拟语气 请查阅共享，掌握好基本形式(特别是与过去事实相反的虚拟语气)和特殊形式
4 分词光棍宣言 切记它们属于非谓语动词，在一个句子当中如果有谓语动词的情况下，排除并列句和主从句的可能性可以考虑分词。区分好逻辑上的动宾（或者被动）关系和逻辑上的主谓（或者主动）关系。
如：分词作定语：
The boy playing the violin over there is my brother.
The women surveyed are all single.
分词作状语:
Walking along the street, I met Lee.
Seen from the hilltop, the town looks beautiful.
特殊的分词结构：独立主格
With the travelling expens rising a lot, we have to be careful in planning a trip.
Weather permitting, we will go on picnic.
The class being over, we can go home.
It being Sunday, we can take a rest at home.
以It being Sunday, we can take a rest at home.为例。
为何填being 而不填is 呢？
原因是如果填is 的话 原句就变成It is Sunday, we can take a rest at home.这是个错句。两个句子并列而没有连词连接来表明两个独立的句子之间的关系。所以填is 是不行。只能填being 现在分词，非谓语动词。因为it 与be 是主谓关系所以填现在分词。wishing

9 need/want/derve/request ving/to be p.p.
