They look cool 怎么变一般疑问句?
变为:Do they look cool?
陈述句变疑问句一般分两种情况:
1,句中有be(am,is,are,was,were)动词时,直接把be动词提到最前面,例如:
He is a college teacher.变为一般疑问句是:Is he a college teacher?
2,句中没有be动词时,根据时态、语态的不同,借助于助动词do,does,did,例如:
She went to swimming last week.变为疑问句:Did she go to swimming last week?(注意这里went 还原,因为do是助动词).希望对你有用.
