问题描述:

怎么把过去式的英语句子改为一般疑问句,否定句和陈述句,怎么把过去式的否定句子改为一般疑问句.陈述句
要详细说明,并且举例,
怎么把英语句子改为过去式,也要举例,能越多而且越详细最好 ,最好解释为什么这么做,

最基本的两种情况:
(1)she ate some apples(她吃了一些苹果)
要改成一般疑问句 就必须要用YES / NO 回答
这里的谓语是ate (动词) 所以将助动词(do)提前,因为是过去式所以用did
Did she eat any apples?(any=some ,any用于疑问句和否定句)因为前面已经有了过去式助动词did 所以后面的eat 用原型
过去式一般疑问句 Did+主语+动词原形+……
否定句只要在动词前加did not就可以了后面的句子有多长不管直接照抄 记得后面的动词还要变原型噢~
she did not eat any apples
一般疑问句否定回答 did not +主语+动词原形+……
(2)There were some flowers(这里有些花)there be 是”有“的意思
这里的是there be 结构 (be:is/am/are) there be 句型译为 某地有某物
一般疑问句 用YES/NO回答的叫一般疑问句
所以将be动词were提前(这里的be动词were是are的过去式)
were there some flowers?
通常遇到there be 句型转换成一般疑问句时,只要把be提前后面就可以原句照抄了~
be(was were)+there+……(照抄)
否定句只要在be动词后面加not就行了
There were not any flowers
总之 过去式的一般疑问句也是过去式
There be(was/were)not……照抄
P.S.一点资料给你参考
过去式:主语+动词过去式+ …
一般疑问句:did +主语+ 动词原型
特殊疑问句 疑问词+did+主语+ …
(只针对第一种情况的)
给你多点例句
陈述句:You are a student.(你是一名学生)
过去式:You were a student
过去式一般疑问句:Were you a student?(你是一名学生吗?)
否定句 :You were not a student(你不是一名学生)
陈:He can swim very well(他能游地很好) could是can 的过去式
过:he could swim very well
问:could he swim very well?(他能游的很好嘛?)
否:he could not swim very well.(他不能游的很好)
陈:there are so many people这里有很多人
过:there were so many people
问:were there so many people这里有很多人吗
否:there were not so many people这里没有很多人
陈there is a tree这里有一颗树
过there was a tree
问was there a tree这里有一颗树吗
否there was no tree这里没有一颗树
陈she eats a lot她吃了很多
过she ate a lot
问did she eat a lot她吃了很多吗
否she did not eat a lot她没有吃很多
陈he likes reading books(like +动词ing)
过he liked reading books他喜欢看书
问did he like reading books?他喜欢看书吗?
否he did not like reading books.他不爱看书
嗯…其实也就这俩种情况最多 只要弄懂了这两种转换其它的也就慢慢会了
