His grandfather is dressed in  sunglass
Has he finished his homework at once?

不懂追问   你finish 少加了ed!
 wear 等于 be in 还等于 be dressed in 
第二个是 现在完成时.把has 提到句型 
Does he have to finish his homework at once?嗯补充告诉你了。嗯 ，那个第一个那个有个 is a man .什么意思？His grandfather wears sunglasses. 同义句His grandfather is a man （)( ）.填空好了就行in sunglasses3q已采纳
