I regret____ harder at school.
问题描述:
I regret____ harder at school.
A.not to have worked
B.not having worked
答
B
regret doing sth/ regret having done sth 后悔.
regret to do sht 遗憾地要.(主要与tell/ inform等【告之类动词】)如:
I regret to tell you that...(很遗憾地通知你 .)那为什么不选A regret to do 表示是对没有做的事情后悔 not regret to do 表示对没有去努力学习感到后悔 (说明这个动作没有做说明没有努力过)regret to do sth表示【很遗憾要......】不是【后悔】经常与【告诉】连用。
