1.They are fighting against air pollution these years.(否定句)
They __are____ __not____ _fighting_____ against air pollution these years.
肯定句变否定句,先看有没有be(初一就是am is are)、情态动词(初一就是can),有就直接在它们后面加not,没有的话就借助动词(初一就是do和does),然后在后面加not,does用于第三人称单数,其他用do.
2.The children are playing football.(一般疑问句)
____Are____ the children ___playing_____ football?
变一般疑问句,先找be,有就直接提到句首,句中一二人称互换,句末用问号.
没有be,就用助动词,动词还原,句末用问号.
3.Laura is reading a book.(就画线部分提问)
________
_What_____ ____is____ Laura ___doing_____?
对动名词短语提问,用what,再把这个动名词短语用doing代替.
4.My mother is shopping in Wangfujing Street.(就画线部分提问)
________________
__Where______ ____is____ your mother ___shopping_______
对地点提问 用where
注意:对划线部分提问的步骤,一放(疑问词);二去(画线部分);三变(一般疑问句),句末问号.
