『肆』 初一英语的语法，线单三，THERE BE 句形，......
There be 句型
1. 定义：There be句型表示某处存在某物或某人。
2. 结构：(1) There is +单数可数名词/不可数名词+ 地点状语.
(2) There are +复数名词+地点状语.
there是引导词，在句中不充当任何成分，翻译时也不必译出。句子的主语是某人或某物，谓语动词be要与主语（某人或某物）的数保持一致。当主语是两个或两个以上的名词时，谓语动词要与跟它最近的那个名词一致。
eg. ① There is a bird in the tree. 树上有一只鸟。
② There is a teacher and many students in our classroom. 我们教室里有一位老师和许多学生。
③ There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。
3. There be句型与have的区别：
(1) There be 句型和have都表示“有”的含义。区别如下：There be表示“某处存在某物或某人”；have表示“某人拥有某物/某人”，它表示所有、拥有关系。 eg.
①He has two sons. 他有两个儿子。
②There are two men in the office. 办公室里有两个男人。
(2)当have表示“包括”、“存在”的含义时，There be 句型与其可互换。
eg. A week has seven days. =There are seven days in a week. 一个星期有七天。
变脸一：否定句
There be句型的否定式的构成和含有be动词的其它句型一样，在be后加上not或no即可。注意not和no的不同：not是副词，no为形容词，not a/an/any + n. 相当于no+ n.。例如：
There are some pictures on the wall. →There aren't any pictures on the wall. =There are no pictures on the wall.
There is a bike behind the tree. → There isn't a bike behind the tree. =There is no bike behind the tree.
变脸二：一般疑问句
There be句型的一般疑问句变化是把be动词调整到句首，再在句尾加上问号即可，此为\"调整法\"。但同时要注意：当肯定句中有some时，要将其改为any（否定变化也一样）。看看下面两句是如何\"改头换面\"的吧：
There is some water on Mars. → Is there any water on Mars?
There are some fish in the water. →Are there any fish in the water?
变脸三：特殊疑问句
There be句型的特殊疑问句形式有以下三种变化：
① 对主语提问：当主语是人时，用\"Who\'s+介词短语?\"；当主语是物时，用\"What\'s + 介词短语?\"。注意：无论原句的主语是单数还是复数，对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如：
There are many things over there. →What's over there?
There is a little girl in the room.→Who is in the room?
② 对地点状语提问：提问地点当然用"Where is / are+主语?\"啦！例如：
There is a computer on the desk. → Where is the computer?
There are four children on the playground. →Where are the four children?
③ 对数量提问：一般有两种句型结构：
How many+复数名词+are there+介词短语？
How much+不可数名词+is there+介词短语？
1．作主语
作主语用的动词不定式常常用it替代，动词不定式（或短语）放在后面。例如：
It's easy to get lost in a big city like Tokyo．在东京这样的大城市容易迷路。
It is terrible to see the ship sinking into the sea．目睹轮船沉入大海，真是太可怕了。
2．作宾语
Indians like to eat hot food．印度人喜欢吃辣味食品。
They need to look at a map．他们需要查看地图。
有的动词不定式在作带有补足语的宾语时，前面往往带有形式宾语it。例如：
Do you think it necessary for us to learn to wait？你认为学会等待对我们来说很必要吗？
They improved the software to make it easier for people to use computers．他们改进了软件，使人们使用计算机更简便了。
3．作表语
It seems to be an interesting book．它看起来是本有趣的书。
The old man's job is to take care of the flowers in the garden．这位老人的工作是照料花园里的花。
4．作宾语补足语
He told me not to bring you anything．他叫我不要给你带任何东西。
Who taught you to play the music？谁教你弹这支曲子的？
5．作定语
动词不定式作定语时，要放在它所修饰的名词或代词后面。例如：
In my dreams I always have very difficult jobs to do．我在梦里总是做一些艰难的工作。
Every day he made one of the smaller animals bring him something to eat．他每天叫一个小动物给他带来吃的东西。
6．作状语
（1）表示目的
You can hide under my seat when the conctor comes to check the tickets．当列车员来查票时，你可以藏在我的座位下面。
In his third year，he left Harvard to work for a company called Microsoft．在三年级时，他为了去微软公司工作而离开了哈佛大学。
（2）表示结果
动词不定式作状语表示结果时常与副词too或enough连用。例如：
It's too heavy to carry．太重了搬不动。
The Californian ship arrived too late to save more people．加利福尼亚号来得太晚，没能挽救更多的人。
7．和某些形容词连用
和动词不定式经常连用的形容词有sure，ready，happy，sorry，afraid等。例如：
He's very happy to see his wife．他见到妻子非常高兴。
I'm sorry to trouble you．很抱歉打扰你了。
8．和疑问词who，what，when，where，which，how构成不定式短语作宾语。例如：
I don't know how to use a computer．我不知道怎样使用计算机。
Can you tell me when to start？你能告诉我什么时候出发吗？

『陆』 英语语法三单问题
这里涉及到两个复知识点;
第一： not only ... but also
若连接制两个成分作主语，其谓语通常与靠近的主语保持一致
not only 用在句首时，句子需要倒装
第二：should must这类词后面跟动词的话必须用动词原形
在这里not only 。。。but also连接的主语为同一个“a leader”谓语动词需要用第三人称单数形式，两处都应该用has
