陈述句变一般疑问句方法及练习
1．检查句子中有无be动词或can, may等等情态动词，当句子中有be动词或can, may等等情态动词时，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can, may等等情态动词后面加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. 当句子中既没有be动词，也没有can, may等等情态动词时，则查看句子主语， ①如果句子主语为非单数第三人称单数(you, they, we以及复数名词)时，在主语前加助动词do变问句, 在主语后谓语动词前加助动词don’t（I, you,以及复数)变否定。 ②如果句子主语为单数第三人称单数时（单数名词，she, he, it）在主语前加助动词does变成问句；在主语后谓语动词前加助动词doesn’t（单数名词，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 否定句→ She doesn’t have a little brother.
