一般疑问句(一)、定义: 用 Yes 或 No 作答的疑问句叫一般疑问句
(二)、特点:以 be 动词、助动词或情态动词开头
例:Is your father a teacher Does Tom like apples Can Jenny speak English (三)、陈述句变成一般疑问句的方法:1、 看陈述句中有没有 be 动词(am、is、 are、 was、 were)或情态动词(can,shall, must, may ,could 等),假如有,将其提到句首,句末打上问号即可
例:It is rainy today
→Is it rainy today Tom's father can play the piano
→Can Tom's father play the piano 2、假如句中没有 be 动词或情态动词,则找实义动词,并在句首加助动词do、does 或 did,且原句的谓语动词要变回原形(一请一还原)
(1)They go to school by bike
→Do they go to school by bike(2)Bill gets up at 6:30 every day
→Does bill gets up at 6:30 every day(3)The students saw a film yesterday
→Did the students see a film yesterday注:(1)在句首使用助动词 do 还是 does,取决于主语是否第三人称单数
(2)在陈述句与疑问句互转化中,第一人称(I)和第二人称(You)要互换,即 I 变→You,You 变→I
I usually have lunch at school
→Do you usually have lunch at
