英语：把肯定句改成否定句和疑问句

改否定句应该在be动词（也就是am,is,are及其过去式was,were)后面加not,如果没有be动词,就在动词前面加助动词（do,does及其过去式did）再加not
1.I was not(was not=wasn't,后者是缩写形式）my clothes every day
有be动词 was ,直接加not
2.He did not（did not=didn't )drink any coffee yesterday
这里dreak应该是楼主打错了吧,是drink,“喝”.yesterday是过去式的标志词之一,所以应该用过去式,并且drink是行为动词,前面应加助动词,用did（前面已说是过去式）,再加not.some改为any,改否定句时,句中的some一定要改为any.
3.He was not jumping this time yesterday.
这个句子是过去进行时,但楼主据我开头说的,同样只需在be动词was后面加not就可以了,这里不用过多考虑时态.
改疑问句同改否定句很相似,在有be动词的情况下,将be动词搬到开头.没有be动词就有行为动词,根据人称时态,人称方面如果是he,she,就用助动词does,如果是they,we,you,I就用do,时态方面如果是过去式就用did,一般时就用do或does,先要考虑时态,在考虑人称,也就是说如果时态是过去式,无论是什么人称都用did,时态是一般时再根据人称选择用do或does,选择了助动词再将助动词搬到开头就可以了.后面再详细讲解.
1.Were you your clothes every day?
这句很简单,但要注意,I was是“我是...”的意思,反过来别人问你,就会问“你是...?”所以这时的翻译就是“were you...?”,你再来回答时,就是“Yes,I was.”或者“No, I wasn't”
2.Did he drink any/some coffee yesterday?
这里虽然是he,但先考虑时态,既然是过去式,直接用did,不需要管人称了,还有这里我将some改成了any/some,因为改疑问句时some既可变为any,也可直接用some,区别是some更希望得到别人的肯定回答,这里没有特殊语气背景的话,还是用any好
3.Was he jumping this time yesterday ?
这里既有be动词,也有行为动词jumping,但这里的was是帮助jumping构成过去进行时,所以这里的was是当助动词用,因此这个句子成分就是 助动词was+行为动词jumping,所以很清楚将was搬到开头
希望采纳

1、I was not my clothes every day.
Were you your clothes every day?
2、He did not drink any coffee yesterday.
Did he drink any coffee yesterday?
3、He was not jumping this time yesterday.
Was he jumping this time yesterday?
ok ok 第二句用的drink过去式应该是drank

1、I was not my clothes every day.
Were you your clothes every day?
2、He did not drink any coffee yesterday.
Did he drink any coffee yesterday?
3、He was not jumping this time yesterday.
Was he jumping this time yesterday?
第2的句的“dreak”错了，应该是“drink”
