we\'ll carry on with it ___we can get enough money.

问题描述:

we\'ll carry on with it ___we can get enough money.
--the experiment is of particulsr importance.
--i see.we'll carry on with it ___we can get enough money.
A.untilB.unlessC.whetherD.however
请问答案选D对么?为什么?

选C,----这个试验非常重要.
----我知道,不管是否获得足够的资金,我们都会实行下去.
B明显是错误的.unless可以等同于“if not”换进去就变成了we'll carry on with it ifwe can not get enough money.
跟句意矛盾,所以不可能是B
而A的意思直到我们得到足够的钱我们才会去实行它跟--the experiment is of particulsr importance.
D 等于no matter how,放进去解释就是不管我们怎样得到足够的钱,我们都会实行下去的
