MY PARENTS STARTED OFF A ABOUT 5 O'CLOCK IN THE MORNING. TYEY __BY NOW. A:WOULD BE ARRIVING
B:SHOULD HAVE ARRIVED C:WOULD HAVE ARRIVED D:SHOULD BE ARRIVING

你好。答案是A

1 SHOULD HAVE ARRIVED ==ARE supposed to have arrived

2 by now ------需要用完成时时态搭配。

3 ARE supposed to ==are thought to -----
被认为- -- --

B:SHOULD HAVE ARRIVED 是对的.
根据句意,my parents 是应该到达了.should have done 是对过去事情的比较肯定的推测,“应该.”的意思.
