语法解析:一般过去时

  (一)定义

  一般过去时主要用来表示过去某个时间里发生的动作或状态。常与表过去的时间状语连用。如:

  He came here yesterday.

       We visited Paris last week.

  (二)基本结构

  一般过去时的句子结构一般为:

  主语+was/were/did+其他成分

  如:

  She was at the party yesterday evening.

  They went to the park this Friday.

  He told me that I could leave for Shanghai.

  (三)主要用法

  1、表过去某个时间会发生的动作或状态

  The dog had a house of its own just now.

  She came to see me yesterday afternoon.2、表过去习惯性或经常性的动作或状态

  I smoked a lot when I was a college student.

  You were always at home on weekends last month.【注意】

He used to smoke a lot. (他过去烟瘾很重。)

  (四)动词的过去式

  动词过去式的变化规则主要有:

  1、+ed

  大部分动词都直接在词尾加ed。如:played、worked

  2、+d

  以不发音的e结尾的动词,直接在词尾加d。如:deleted(删除)、faded(消逝)

  3、+ied

  以辅音+y结尾的动词,要改y为i,再加ed。如:studied、cried

  4、+ked

  以ic结尾的动词,要先加k再加ed。如:panicked(恐慌)、trafficked(贩运)

  5、双写+ed

  当单词以重读闭音节结尾时,要双写最后一个辅音字母,再加ed。如:stopped、padded(填塞)

  6、不规则

  不规则的动词关键在于多识记,如:put-put,come-came,go-went,take-took,lend-lent。

  (五)标志性词语

  1、yesterday系列

  这类时间状语主要有:yesterday、yesterday morning/afternoon/evening、the day before yesterday等。如:

  I met an old friend on the street the day before yesterday.

  The band gav癫痫病护理的方法是哪些e a performance at the bar yesterday evening.

  2、last系列

  这类时间状语主要是指由“last+时间单位”引导的短语:last Wednesday / last week / last month / last summer / last year等。如:

  They spent their holiday in Berlin last month.

  She left for Beijing on business last week.

  3、ago系列

  这个短语的意思是“多长时间之前”,其结构为:时间段+ago。如:

  The train left five minutes ago.

  The plane arrived an hour ago.

  4、just now

  该短语表示“刚才”。如:

  Our English teacher gave us a lecture on British accent just now.

  The principal told us just now that there would be a great change in our school this coming summer.

  5、the other day

  I left my handbag on the train to Tokyo the other day.

  She ran into her primary school English teacher at the party the other day.

  6、“this+过去时间”系列

  She visited the museum this Thursday.

  My aunt came here this Tuesday.

  (六)句型转换

治疗癫痫病哪些西药: normal; font-variant-east-asian: normal; white-space: normal; padding: 0px; font-stretch: normal; line-height: 28px; text-indent: 2em;">  1、was/were

  当句子的谓语动词是由was/were引导时,was/were就相当于助动词,其否定句直接在后面加not即可,疑问句只要把was/were提前即可。如:

  原句:Kerry was in her hometown last Sunday.

  否定句:Kerry wasn't in her hometown last Sunday.

  一般疑问句:Was Kerry in her hometown last Sunday?

  划线部分提问:Where was Kerry last Sunday?(提问in her hometown)

  2、did

  当句子的谓语动词为实义动词(行为动词)时,其否定句和疑问句的变化要借助助动词did。如:

  原句:Kerry showed me around her hometown last Sunday.

  一般疑问句:Did Kerry show you around her hometown last Sunday? Yes, she did. / No, she didn't.

  划线部分提问:When did Kerry show you around her hometown? (提问last Sunday)

  3、非was/were/did

  当句子的谓语动词为非was/were/did的动词时(即谓语动词中含有情态动词或助动词时),其否定句和疑问句的变化与was/were的情况相同。如:

  原句:It could be worse.

  否定句:It couldn't be worse.

  一般疑问句:Could it be worse? Yes, it could. / No, it couldn't.

  划线部分提问:What could be worse?(提问it)
