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。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)
