如何将一般现在时的肯定句改成否定句。
不含有“be”动词的一般现在时的肯定句,在改成否定句时,首先要想到助动词“do”或“does”,构成“do not / don’t ”或“does not / doesn’t ”否定结构, 其中“does”只能用在主语是第三人称单数时,还要记得把动词的第三人称形式改为原形;“do”用在主语不是第三人称单数时。
例如:1、He writes the new words every evening. ( 肯定句 )
He doesn’t write the new words every evening. ( 否定句 )
2、We go to school on Sundays. ( 肯定句 )
We don’t go to school on Sundays. ( 否定句 )
3、Xiao Li reads newspaper every day. ( 肯定句 )
Xiao Li doesn’t read newspaper every day. ( 否定句 )
4、The blue bird sings every morning. ( 肯定句 )
The blue bird doesn’t sing every morning. ( 否定句 )
