Did you _____a book last year?(read)
Look!They _____kites(fly)
He said he _____already.(arive)
Be_____,please.(seat)

Answer 1

第一个saw yesterday代表昨天 所以是过去式 第二个 have finished 因为句子里有already 表示已经 就是说 我们已经完成我们的工作了 所以用完成时 第三个 原型read 因为did已经表示了这个句子的时态 不需要后面再表示 第四个 are flying 因为有look 所以表示是正在进行的状况 第五个 has arrived 同上 完成时 但是是单数 最后一个seated 因为be后面要跟形容词
