I ________ in the kitchen when you phoned
1 I ______ in the kitchen when you phoned
A must have been ( " must have done" 表推测过去必然发生的事情, 语气较强,具有肯定的意思 )
B must be( 为啥不可以?)
2 Would you sooner I __ _______ my paper tomorrow morning?
A handed in( 这个表示上交, 这我知道, 可整个句子看下来 咋这么别扭呢! 我分析了一下语法结构, 好像是错误的! )
B will have handed in
C hand in
D will hand in
正确答案 A A
I ________ in the kitchen when you phoned1 I ______ in the kitchen when you phonedA must have been ( " must have done" 表推测过去必然发生的事情, 语气较强,具有肯定的意思 ) B must be( 为啥不
1 看到后面的phoned,表示是过去式,则前面绝对不能用一般时的must be,且must have been是对过去的事情的推测,所以.
2 第二题那里是有个“I”
1.you phoned是过去时,must have been done是推测里的过去时结构
1.当电话在当时产生的影响,用A好些。
2.嗯,有道理。
