GWD26-Q12 The most vexing problem faced by researchers exploring wind-powered generation of electricity is achieving a constant flow of power from an unpredictable natural source that meets demand, but so the flow does not overload electrical grids with sudden voltage increases
A. achieving a constant flow of power from an unpredictable natural source that meets demand, but so the flow does not overload B. achieving a constant flow of power from an unpredictable natural source, which meets demand but without overloading C. how to achieve a constant flow of power from an unpredictable natural source, a flow that meets demand but does not overload D. how to achieve a constant flow of power from an unpredictable natural source, but a flow that meets demand without overloading E. how a constant flow of power from an unpredictable natural source can be achieved, which meets demand but does not overload 答案是C, A哪里错了?作者: y2k01y2ko1 时间: 2011-1-17 19:37

that就近修饰natural source错 but前后也不平行作者: ing315 时间: 2011-1-17 22:54
The problem is how to achieve flow......., a flow. perfectly explained the flow. A is wrong because "but so" is not correct.作者: lunzy 时间: 2011-8-31 01:53
我从语义上快速直接排除了AB 因为vexing problem is achieving a constant...意思是不对的 不能说最烦人的问题是获得(了)一个稳定的... 加一个not意思才稍微顺点——最烦人的问题是不能获得一个稳定的... 当然how to是最好的——最烦人的问题是如何获得一个稳定的... 不知道我的理解对不对作者: qilu8989 时间: 2011-8-31 02:28
problem---how to....
