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】
过去习惯的表达经常会用到used to do,但用了这个短语,往往意味着现在这个习惯已经没有了。如:
§ 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 gave 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
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)
