问题描述：
从句i insist that a doctor ____immediately
a .has been sent for
b.sends for
c.will be sent for
d.be sent for
这道题我完全没有概念,
为什么abc都不对?
答
insist后面的从句要用动词原形
因此要选择D be sent for
我坚持马上请医生
答
D
用法是：insist that sb.(should) do...
建议某人做……
所以要用动词原形。
答
楼上不是正解,我说一楼
D.be sent for
虚拟语气,should+动词原形,省略了should .不要被楼上误解了.
