新概念第一册67-72一般过去式(be动词);there be(was/were)句型;
一般过去时:
am/is/are--->was/were [详细语法知识见:语法汇总第五部分]
新概念补充了一个新知识原来一般过去式也有加be的场景,罗列如下:
类型1,be 动词一般过去式:was/were+表语
例句:I was at the church on Sunday.
类型2,动词的过去式,+ed
例句:I ate a carrot yesterday.
(与过去进行时的区别,was/were+doing。加了ing,就是一个进行中的时态了)
一般过去时疑问句:do 变为did
What did you do last night?
一般现在时:What do you do last night? 这里做一下对比
拓展了啊①:didn’t和wasn't/weren't 的区别用法
例句:I didn't go to the park yesterday 此处为啥用didn't,不用wasn't
go是动词,didnt表示否定过去的动作.wasn‘t是否定过去的状态,后面接形容词或者名词,或者是过去进行时才能用.e.g.I wasn’t
going to the park this time yesterday.(我昨天这个时候不是正在去公园)或者I wasn‘t in the
park yesterday.(我昨天不在公园)
---我百度的
简单说,句子里有实义动词的就did,没有的就用be动词,一山不能有俩虎子,所以be和实义动词的原形就不能一起出现了。
拓展了啊②:一般过去时的否定用法
类型1:was/were +not
例句:I was at the hairdresser’s yesterday.
改为否定:I wasn't at the hairdresser‘s yesterday.
类型2:didn't+行为动词原形
例句: It snowed yesterday.
改为否定:It didn’t snow yesterday.
练习题摘自新概念:
用was 或者were填空。
1.The children___ in the park
2.I ___ born in beijing
3. The students in the classroom
4.____you at the grocer’s ?Yes,I ___ (Tips:grocer是杂货商的意思,‘s=is,翻译就是杂货商的,名词的所有格,所有格就是谁所有,杂货商所有那当然就是杂货店啦)
5.Mr.Brown ___ in the garden just now.
---------分割线-----------
There be句型
一般现在时的there be例句:
There is a car race near our town every year.
一般过去时的there be例句:
In 1995, there was a very big race.
你猜这里为啥是用was,在1995年一个明确的过去时间所以是过去式,并且”a big race“一个大比赛,单数所以就was咯
(波波吐槽,好嘛be 是一块砖,就往时态里搬啊。。)
