新概念第一冊67-72一般過去式(be動詞);there be(was/were)句型;
一般過去時:
am/is/are--->was/were [詳細(xì)語法知識見:語法匯總第五部分]
新概念補(bǔ)充了一個新知識原來一般過去式也有加be的場景,羅列如下:
類型1,be 動詞一般過去式:was/were+表語
例句:I was at the church on Sunday.
類型2,動詞的過去式,+ed
例句:I ate a carrot yesterday.
(與過去進(jìn)行時的區(qū)別,was/were+doing。加了ing,就是一個進(jìn)行中的時態(tài)了)
一般過去時疑問句:do 變?yōu)閐id
What did you do last? night?
一般現(xiàn)在時:What do you do last night? 這里做一下對比
拓展了?、伲?/span>didn’t和wasn't/weren't 的區(qū)別用法
例句:I didn't go to the park yesterday 此處為啥用didn't,不用wasn't
go是動詞,didnt表示否定過去的動作.wasn‘t是否定過去的狀態(tài),后面接形容詞或者名詞,或者是過去進(jìn)行時才能用.e.g.I wasn’t
going to the park this time yesterday.(我昨天這個時候不是正在去公園)或者I wasn‘t in the
park yesterday.(我昨天不在公園)
? ?? ---我百度的
簡單說,句子里有實(shí)義動詞的就did,沒有的就用be動詞,一山不能有倆虎子,所以be和實(shí)義動詞的原形就不能一起出現(xiàn)了。
拓展了?、冢?/span>一般過去時的否定用法
類型1:was/were +not
例句:I was at the hairdresser’s yesterday.
改為否定:I wasn't at the hairdresser‘s yesterday.
類型2:didn't+行為動詞原形
例句: It snowed yesterday.
改為否定:It didn’t snow yesterday.
練習(xí)題摘自新概念:
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是雜貨商的意思,‘s=is,翻譯就是雜貨商的,名詞的所有格,所有格就是誰所有,雜貨商所有那當(dāng)然就是雜貨店啦)
5.Mr.Brown ___ in the garden just now.

There be句型
一般現(xiàn)在時的there be例句:
There is a car race near our town every year.
一般過去時的there be例句:
In 1995, there was a very big race.
你猜這里為啥是用was,在1995年一個明確的過去時間所以是過去式,并且”a big race“一個大比賽,單數(shù)所以就was咯
(波波吐槽,好嘛be 是一塊磚,就往時態(tài)里搬啊。。)
