Many financial experts believe that policy makers at the Federal Reserve, now viewing the economy as balanced between moderate growth and low inflation, are almost certain to leave interest rates unchanged for the foreseeable future.
A. Reserve, now viewing the economy as balanced between moderate growth and low inflation, are
B. Reserve, now viewing the economy to be balanced between that of moderate growth and low inflation and are
C. Reserve who, now viewing the economy as balanced between moderate growth and low inflation, are
D. Reserve, who now view the economy to be balanced between that of moderate growth and low inflation, will be
E. Reserve, which now views the economy to be balanced between moderate growth and low inflation, is
我选的是D，答案是A 从句的主语是policy makers,所以E是单数错 B的and are之前没有动词和are对称，此结构错误 C的话是我看 Reserve who, now viewing 不顺眼就排除的 最后就剩D和A 首先view 后面加as或加 to be有没有什么讲究啊？我没把这个作为一个衡量依据 我选D是因为我觉得是policy makers认为economy as balanced ...，所以leave interest rates unchanged 。 可如果选A的话now viewing the economy 就有可能指代financial experts 了，所以我选了D 请各位NN指教 |
