we+are+washing+some+apples改为否定句?
把“We are washing some apples.(我们正在洗苹果。)”改为否定句是:
We are not washing any apples.(我们没有在洗苹果。)
英语的肯定句变为否定句:
Ⅰ、如果句子中存在be动词(am/is/are/was/were),变为否定句只需要在be动词后+not:
eg:He was playing the piano at that time→He wasn't playing the piano at
that time.他那时(不)在弹钢琴。
Ⅱ、如果句子中存在情态动词will/would,may/might,shall/should,can/could,need,ought以及had better,在这些后+not:
eg:You had better get up early→You had better not get up early.你最好(不要)早点起床。
注意:ought to应该…在肯定句中“to”不得省略,在疑问句或否定句中省略。
Ⅲ、如果句子中仅有实义动词,则需要添加助动词,在助动词后+not:
非单三的一般现在时:在动词前+don't 单三的一般现在时:在动词前+doesn't
一般过去时:在动词前+didn't 完成时:在have/has/had后+not
被动:在第一个助动词后+not
Sth be not+done/Sth have(has)not been done
Ⅳ、固定搭配:tell sb(not)to do sth,let sb(not)do sth,…
We are not washing any apples .
我们不洗任何苹果 。
( 如上句子,已经修改为了否定句
句子的形式 。)
改为否定句是:We are not washing some apples.
