there was trouble with the Hubble_____ A from the beginning B before
选择哪个,分别说出为什么对与错
这个题选A
句子的意思是:
从一开始,哈勃望远镜就出了些问题.
from the beginning,意思是:从一开始,有这个时间状语的句子,可以跟过去时,如:
I was opposed to the plan from the beginning.我从一开始就反对这个计划.
但是before单独用作时间状语,并放在句末,往往用现在完成时,比如:
I have been to London before.
He has seen the film before.
给出句子用的是过去时,所以这里用before是不妥当的.
