据专家权威分析，试题“There _ a small house here 20 years ago.[ ]A. isB. are C...”主要考查你对  there be 句型，一般过去时，动词过去式  等考点的理解。关于这些考点的“档案”如下：

there be 句型一般过去时，动词过去式

考点名称：there be 句型

• There be句型：
  是英语中常用句型，意思是“有”，表示“人或事物的存在”。
  There在此结构中是引导词，已经没有副词“那里”的含义。
  There be后面的名词是句子的主语，属倒装结构。常用“There + be+名词+地点/时间状语”的结构。 
  

• There be结构的用法：
  A、肯定结构：
  There be句型的肯定结构表示“某处存在某物或某人”或“某时发生某事”。 
  a. There is+单数可数名词/不可数名词+地点/时间状语。 
  例：There is a cat under the chair. 椅子下面有一只猫。 
         There is some water in the bottle. 瓶子里有些水。 
  b. There are +复数名词+地点/时间状语。 
  例：There are some apples in the basket. 篮子里有一些苹果。
  B、否定结构：There be句型的否定结构是在谓语动词be的后面加“not (any)”或“no”. 
  例：There are no tables in the room. 或者There are not any tables in the room. 房间里没有桌子。
  C、疑问结构：There be句型变成疑问式时，要把there和谓语动词be的位置互换。 
  例：Is there a pen in the schoolbag? 书包里有一支笔吗？

• Therebe结构和have的区别与联系:
  1.区别点：
  there be 意为存在，强调某地有某物，不表示所属关系；
  have 表示所有关系， 强调某人或某地有某物，这是其基本用法。如：
  There are some trees in front of the house.房前有些树。
  Tom has many friends in China.汤姆在中国有许多朋友。
  
  2.相同点：
  在表示结构上的含有时，既可以用there be 句型，也可以用have（has） 来表示。如：
  中国有许多长河。
  There are many long rivers in China.
  China has many long rivers.
  三月份有多少天？
  How many days are there in March?
  How many days has March?

• There be结构中的be动词的确定：
  A、there be 结构中的谓语动词be在人称和数上应与其后的主语保持一致。主语是不可数名词或单数可数名词时用is，是复数时用are。 
  例：There is a flower in the bottle. 瓶里有一朵花。 
          There is some money in the purse. 钱包里有些钱。 
  B、若句子中有几个并列的主语时，be的形式要与离其最近的一个主语在人称和数上保持一致。 
  例：There is a boy, a girl and two women in the house. 房子里有一个男孩,一个女孩和两个妇女。 
          There are ten students and a teacher in the office. 办公室里有十个学生和一个教师。
  
  There be结构的句型转换：
  A、否定句：
  there be的否定式通常在be后加not构成（在口语中be时常与not缩写在一起）。如果句中有some，一般要变成any。 例：
  There are some children in the picture. 
  There aren't any children in the picture.
  B、一般疑问句及其答语：
  把be提到there前，首字母大写，句末用问号即可。其肯定答语是Yes, there is / are；否定答语为No, there isn't / aren't。 例：
  — Are there two cats in the tree?
  — Yes, there are. (No, there aren't.)
  C、特殊疑问句及其回答 
  a. 提问句子的主语（包括主语前的修饰语）时，句型一律用“what is+地点介词短语？”（无论主语是单数还是复数都用is）。
  例：There are some birds in the tree. →  What's in the tree? 
  b. 就there be后面的地点状语进行提问时，句型用“where is/ are+主语？” 
  例：There is a car in the street. → Where is the car?
  c. 提问可数名词（主语）前的数量时，用how many，句型结构为“how many+ 复数名词+are there+其它）”（主语无论是单数还是复数，be通常要用are）。 
  例：There are three books on the desk. → How many books are there on the desk?

考点名称：一般过去时，动词过去式

• 一般过去时：
  表示过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为；过去主语所具备的能力和性格。
  be动词在第一人称是单数和第三人称是单数是用was，其余用were。
  a. 表示在过去时间里所发生的动作或存在的状态，常与表示过去的时间状语。
  yesterday（昨天）、last week   （上星期）、an hour ago（一小时前）等连用。 
    例：I went to the zoo with my father last Sunday. 上周日我和我爸爸去动物园了。
       They weren't able to come because they were so busy.他太忙了，所以去不了。
  b. 表示在过去一段时间里，经常性或习惯性的动作或状态。 
    例：My brother watched the World Cup every day last month.上个月哥哥每天都看世界杯比赛。

• 一般过去时句法结构：
  肯定形式
  主语+动词过去式+其他
  例句：She often came to help us in those days.
  
  否定形式
  ①was/were+not；②在行为动词前加didn't，同时还原行为动词
  例句：I didn't know you like coffee
  
  一般疑问句
  ①Did+主语+do+其他？ ②Was\Were+主语+表语?
  例句：Did I do that?
  用表格整理如下：

  肯定式	疑问式	否定式	疑问否定式
  Iworked	Did I work?	I did not work	Did I not work?
  He(She,It) worked	Did he(she,it) work?	He(she,it) did not work	Did he(she,it) notwork?
  We worked	Did we work?	We did not work	Did we not work?
  You worked	Did you work?	You did not work	Did you not work?
