(1)Mr.Green is ___old teacher___Shanghai Language School. A.an...in the B.an...of C.the...at D.an...with 为什么要选b的理由 (2)Where do you come from?为什么要用do和come (3)We don't hand in our homework every day .为什么要用don't hand
个人认为b是没有问题的,A中如果是.an...in a 也是正确的选项。 变成特殊疑问句要有助动词或者be动词或者情态动词,而come是一个实义动词,要有助动词 where are you from=where do you come form 变成否定句实义动词又有助动词帮助。 你回家东看看语法书,就可以了...
