There be 句型详解
这是一个固定句型，there be表示存在、有等含义，引出后续具体的名词成分。
there已经固化成一个引导词，所以不需要分析其成分属性。
There be句子整体其实是一个倒装结构，be.后面的名词才是句子的主语。
常见的完整there be句型如下：
There be + sth. + 地点/时间/状态.
其中地点/时间/状态可以存在一个或多个，也可以仅仅只是There be + sth.。
There be句型可以和助动词、情态动词等结合使用。
- There will be a holiday tomorrow.
主谓一致原则
如上所述，there be句型的主语是be之后的名词，所以系动词be的单复数由其后的名词决定：
1. 当动词be后所接的名词是单数可数名词或不可数名词时，be应该使用单数形式is。
2. 当其后所接的名词是复数的可数名词时，be应该使用复数形式are。
就近原则
如果there be后跟多个并列名词，离there be最近的名词决定整体的单复数形式，即最近的名词决定be是使用is/was还是are/were。
- There are five books and a cup on the table.
- There is a cup and five books on the table.
句式
一般疑问句
There be句型的一般疑问句形式是将be放在there之前，回答时用yes或no，后接简单答语。
A: Is there a cup on the table?
B: Yes, there is. No, there isn't.
特殊疑问句
There be句型的特殊疑问句主要有以how many或how much做引导词的两种情况：
- How many students are there in your school?
- How much money is there in your pocket?
反意疑问句
- There is a cup on the table, isn’t there?
作主语、宾语、或状语
非谓语形式的there to be和there being结构可用作主语、宾语、或状语等。
there being
- I never dreamed of there being a picture on the wall.
- There being no bus, we had to walk home.

注意! 该用法过于口语化，Enpuz 当前暂不支持解析
there to be
用作介词for的宾语：
- It's a great pity for there to be much trouble in the class.
很多动词如：like、prefer、hate、want、mean、intend、expect、consider等等也经常后接there to be：
- I don't want there to be any misunderstanding.
- Students hate there to be too much homework.
- We expect there to be more discussion about this.
特殊句型
There be + 主语 + doing. +介词短语.

含有如下两层含义：
1. 用来表明一个特定的动作是不可能的、不可行的。

注意! 该用法过于口语化，Enpuz 当前暂不支持解析

更多

Yes, you must. 是的，需要呆下去。
need have done的否定式或疑问式，表示本来不必做某事，但事实上却做了:

because、since、as、for 的区别
because可用来回答why提出的问题；可以引导表语从句；可用于强调句等，而其余三者则不行。
because表示的是必然的因果关系，语气最强，通常放在主句之后，若需强调则放在主句之前。
since、as所表示的原因是人们已知的，是对已知事实提供理由，而不表示直接原因。它们引导的从句通常放在主句之前，有时也放在主句之后。
- As he wasn't ready in time, we went without him. 因他未及时准备好，我们没等他就先走了。
- Since we have no money, it's no good thinking about a holiday. 既然我们没有钱，考虑度假有什么用。
至于for, 它是并列连词(其余三者为从属连词)，它有时可表示因果关系 (通常要放在主句之后，且可与because换用)；有时不表示因果关系，而是对前面分句内容的解释或推断 (也要放在主句之后，但不能与because换用)。试比较:
- The ground is wet, [for/because] it rained last night. 地面是湿的，因为昨晚下过雨。
- It must have rained last night, for the ground is wet this morning. 昨晚一定下过雨，你看今天早上地面是湿的。
