---How is that,Joan?---Yeah,it's from the boss.She ( ) first whether she likes it.
A．shall go
B.ought to have gone
C.should go
D.must have go
請(qǐng)講詳細(xì)點(diǎn)選哪個(gè)
還有為什么不能選C
AC應(yīng)該都可以表“應(yīng)該”嘛
但麻煩講一下為什么不選其他的，THANKS!
還有could have done和might have done都有本可以做而沒(méi)做成的意思，那么二者有什么區(qū)別呢？
比如這個(gè)題
---John saw a three-year-old cjild walking alone in a sjopping mall,so he took the child home immediately and called the police.
---But he_____have waited withthe child until the parents returned.
A.shouldn't B.could C.would D.might
為什么選B而不選D呢？
再次THANK YOU ALL!
