look “看起来”在这个句子中是系动词后跟形容词作表语,所以用 happy,而不用副词 happily
整句翻译：你看起来非常高兴,什么好消息?
1.David,do you know when _______?
A.will he come here B.he will come here C.he came here D.did he come here
(答案是B,求为什么选B,而不是A)
解析：Do you know + 连接词+ 宾语从句,而宾语从句是正常语序,即：主语+ 谓语,所以答案B
而 A 是特殊疑问句
2.When will Tom come back?
---He will come back ________two days.
A.in B.at C.after D.for
(答案是A,求为什么选A,而不是D)
in two days 两天后,是一般将来时的时间状语,而句子：He will come back 是一般将来时,所以答案A
而 D for + 一段时间 经常用于现在完成时,如：He has worked her for two days.
