据专家权威分析，试题“短文改错。 Not too long ago, people can't go scuba diving o..”主要考查你对  一般过去时，可数名词（单数名词，复数名词），不定冠词（a，an），人称代词，指示代词，实义动词的过去式  等考点的理解。关于这些考点的“档案”如下：

一般过去时可数名词（单数名词，复数名词）不定冠词（a，an）人称代词指示代词实义动词的过去式

考点名称：一般过去时

• 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。
  基本结构：
  主语+动词过去式+其他；
  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；
  一般疑问句Did+主语+do+其他。

• 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?
  They worked	Did they work?	They did not work	Did they not work?

  记忆口诀：
  一般过去时并不难，过去动作、状态记心间。
  动词要用过去式，时间状语句末站。
  否定句很简单，didn't 站在动原前，其它部分不要变。
  一般疑问句也好变，did放在句子前，主语、动原、其它部分依次站。
  特殊疑问句也简单，疑问词加一般疑问句记心间。
  最后一条请注意，动词过去式要牢记！
  
  一般过去时中动词过去式变化规则：
  

  词	构成	举例
  一般情况	词尾+ed	动词原形	过去式和过去分词
  		look talk	looked talked
  以不发音字母e结尾	词尾+d	like arrive	liked arrived
  以“辅以字母+y”结尾	变y为i，再加ed	fly study	flied studied
  以重读闭音节结尾，且末尾只有一个辅音字母	双写词尾+ed	stop plan	stopped planned

  
  结构句型:
  1．一般句子
  I watched TV last night.
  2．一般疑问句
  Did you watch TV last night？
  3．there be 句型
  There was an apple on the table last night.
  Was there an apple on the table last night

• 一般过去时注意事项：
  1.注意主句与从句中时态的一致性
  如果主句用了过去时，从句中一般也要用过去式，或者过去进行时、过去完成时等。例如：
  He believed that he was right. 他相信自己是对的。
  I didn’t know you were here. 我不知道你在这儿。
  I thought they were with you. 我以为他们和你在一起。
  
  2.在口语中， 一般过去时并不一定指真正的过去，而只是表示一种礼貌性语气。例如：
  I wondered (wonder) if you could do me a favor. 不知你可否帮我一个忙。
  I wanted (want) to ask if I could borrow your car. 我想问问可否借用你的车。
