see to it that the report to George

问题描述:

see to it that the report to George
See to it that the report ___ to George the instant it's typed.
A.is sent B.will be sent C.is sending D.sent
A 为什么
还是不是很清楚···

see to it 意为确保
that后引导从句(the report ____to `````)
从句中:report为主语,被动语态,则,C、D排除
the instent it"s typed 为状语,则时态为一般现在时.选A
B为将来时,不符.我弄不明白的是the instant不是有一。。。就得意思吗,有一种用法是主句将来时,从句一般现在时的用法吗这两者怎么区分题目中的状语没有主将从现 的含义。这是条件状语!!!那这句话该怎么翻译啊~~确保这份报告一被打完就发送给 George
