初中英语时态知识点:一般疑问句的几点注意事项
一般用什么问就用什么来回答。
但以下例外:Is this a pencil? Yes , it is./ No, it isnt.
Is that your backpack? Yes , it is./ No, it isnt.
Are these your parents? Yes, theyre./ No, they arent.
Are those Jims brothers? Yes, theyre./ No, they arent.
当句子中没有be动词,也没有情态动词时,变一般疑问句时,在主语前加助动词do (I, we, you,以及复数), does(第三人称单数she,he,it等)变成问句;
