1、七年级英语下册Unit 1 语法讲解练习一、一般过去时知识讲解1.用法:(1)一般过去时表示过去某个时间或时间段内发生的动作或存在的状态;常有表示过去的时间状语标志,如last night,three days ago,in 1900,before等。e.g.Ivisited my parents last night.He got up at 7:30 yesterday.(2)一般过去时也表示过去经常或反复发生的动作。e.g.Tom always went to school by bus last year.I was often late for school before.2.时间状
2、语(标志词8大类):(1)“last(上一个)+表示时间的单数可数名词(day / month/ week / year等)”,意为“上一”;e.g.last day昨天 = yesterdaylast month 上个月(2)“时间段+ ago(以前)”,意为“多长时间以前”;e.g.two weeks ago五周前(3)“in +过去的年份”,意为“在哪一年”;e.g.in 1918 在1918年,这里要注意区分 in+未来的年份,如 in 2099,这个就要用未来时(4) in the past在过去;(5) then = at that moment在那时。(6)由when,as,th
3、ough等引导的状语从句中,有时从句需用一般过去时。e.g.When Tom came back yesterday night, his mother was cooking dinner.Tom didnt come back home until I finished my homework.(7) since意为“自从”,引导的时间状语从句,从句用一般过去时,主句用现在完成时。e.g.Tom has lived in Kunming since he came here.My parents have been away from my hometown since I went to
4、 the university.(8)大多数情况下,由并列连词and,but和or连接的句子,前后时态需一致。如果其中一部分用了一般过去时,这些词连接的另一部分也需要用一般过去时。e.g.Tom was hardworking, but he was careless.I liked apples and my mother also liked apples in the past.3.谓语动词形式:(1) be动词: was(am / is的过去时);were(are的过去时)。was:主语为单数(包括I)名词,代词,词组或是句子;was是am和is的过去式。were:主语为复数名词,代词
5、,词组或是句子;were是are的过去式。e.g.Iwas a university student three years ago.Mark isnt what he was in the past.They were strangers.(2)实义动词:过去式形式。注意:当谓语动词为实义动词的过去式式时,谓语动词的形式不受主语的影响。e.g.Tom went to Shanghai last summer holiday.My father used to go for a walk after supper.Everything went well at that moment.4.一般
6、过去时中肯定句转换为否定句,一般疑问句以及肯定和否定回答的知识点总结。(1)含有be动词(was/were)的陈述句转换为一般疑问句时,直接把be动词提到句首,然后把“.”转换为“?”即可,其中第一人称I,we和our要相应的转换为第二人称you和your。肯定及否定回答用相对应的be动词来回答即可,但是主语需转换为对应的人称代词(there be句型除外,直接用there来回答);若是肯定句转换为否定句,直接在be动词后面加not,可缩写,可全称;但否定回答只能用缩写。was not = wasnt;were not = werente.g.肯定句: Tom and Mary were fr
7、iends before.否定句: Tom and Mary were not/werent friends before.一般疑问句: Were Tom and Mary friends before?肯定回答: Yes, they were.否定回答: No, they werent.肯定句: The apple was good.否定句: The apple was not/wasnt good.一般疑问句: Was the apple good?肯定回答: Yes, it was.否定回答: No, it wasnt.(2)含有实义动词的陈述句转换为一般疑问句时,需要请助动词did,然
8、后把助动词提到句首,后面的实义动词必须转换为原形。肯定回答和否定回答也用相应的助动词来回答即可,但是主语需转换为对应的人称代词,注意否定回答必须用缩写。若是肯定句变为否定句,直接在助动词did后面加not变为否定形式,放于谓语动词之前,但切记请了助动词,后面的谓语动词必须变为原形。did not = didnte.g.肯定句: I went to the zoo yesterday.否定句: I did not go to the zoo yesterday.一般疑问句: Did you go to the zoo yesterday?肯定回答: Yes, I did.否定回答: No, I
9、didnt.肯定句: She visited her uncle last year.否定句: She didnt visit her uncle last year.一般疑问句: Did she visit her uncle last year?肯定回答: Yes, she did.否定回答: No, she didnt.5.易混项非常需要注意的是,在实际的考题中,时态类考题通常会和固定搭配的短语、使动短语等一起考,来增加难度和区分孩子是否理解透彻。常考的易混点如下:1.make sb +形容词 使某人 +名词使某人成为.do sth使某人做某事2.keepdoing sth 继续做某事,
10、一直做某事3.decide/choose/want/rememberto do sth 决定/选择/想要/记得做某事4.let sbdo sth 让某人做某事5.likedoing sth 喜欢做某事6.haveto do sth 必须做某事7.howto do sth 如何做某事 whatto do 做什么8.Whatdo you mean by.?你是什么意思?9.Its timeto do sth.到做某事的时间了。10.Whats sth like?某物是什么样子的?11.It is +形容词 +to do sth.做某事是的。二、过去时态练习1.Last weekend, my pa
