一般现在时的句子转换

分类: 英语语法 
(1)当句子中有be动词或情态动词时,则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;    在be动词或情态动词后面加not变成否定句.例:①陈述句:She is a student.        疑问句→ Is she a student?        否定句→ She is not a student.     ②陈述句:I can swim.        疑问句→ Can you swim .       否定句→ I can not swim.(2) 当句子中即没有be动词,也没有情态动词时,则在主语前加助动词do (you,以及复数), does(单数she,he,it)变成问句;     在主语后谓语动词前加助动词don’t(I,you,以及复数), doesn’t(单数she,he,it)变成否定句,助动词后的动词要变成动词原形。例:①陈述句:We get up at 7:00 every morning.        疑问句→Do you get up at 7:00 every morning?        否定句→We don’t get up at 7:00 every morning.     ②陈述句:She has a little brother.       疑问句→ Does she have a little brother?       否定句→ She doesn’t have a little brother
