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
祝你早日开窍~

其实和现在时的形式都一样。改疑问句时，两种情况：1.借用助动词did,并提到句子主语之前，主语后面的语序不变，只是谓语动词要由过去式变成原形。He watched TV alone last night.--Did he wach TV alone last night?2.如果句子里的谓语是was或were,就只需把它们提到主语前。例：He was born in September.--Was he born in September?
改否定句也两种情况：在谓语是一般动词时直接在动词前加did't,同时动词由过去时改成原形。I visited my aunt yesterday.--I did't visit my aunt yesterday.2.若谓语动词时be动词，就在was/were后加not.There were a book on the table.--There were not a book on the table.

否定句改疑问句也一样，找准谓语动词，或借助did或直接把be动词网前提。
例I didnt like playing baskerball.--Did you like playing basketball?
He wasn't frendly to his new roommate.--Was he friendly to his roommate?

Answer 3

否定句改疑问句，找准谓语动词，或借助did或直接把be动词往前提。
改一般疑问句，将did，do does be 提前
否定句在谓语动词后加not

Answer 4

(一）
比如:
i told you that yesterday 这句。它是一般过去时态

一般疑问句就应该是：
did you tell me that yesterday?用do来占位置，所以一般过去时态里面的told变原型tell。

否定句：
i didn't tell you that yesterday.和一般疑问句一样，用do来占位置，told变原型tell。

陈述句就是一般过去时态本身的这个句子。

（二）
过去式的否定改为一般疑问句的话，先否定，再疑问。
（1）否定：i didn't tell you that yesterday.
（2）疑问：didn't you tell me that yesterday?

陈述句还是一般过去时态本身的这个句子。

Answer 5

陈述句：She eated an apple an hour ago.
否定句 she didn't eated an apple an hour ago
一般疑问句 Did she eat an apple an hour ago?
Did she not eat an apple an hour ago?
