His political analysis is not new, but it could hardly be _____.
A.less eloquent
B.more eloquent
C.more than eloquent
D.less than eloquent
我选了B，但网上有些人给出的答案是D，我选择b的原因是，我感觉it could hardly be more eloquent表示他的剖析简直不可以愈加有说服力了。期望能有老师可以剖析一下B与D的差别。
《韦氏高阶》less than:
less than
:not completely or not at all
She wasless thanhappy with the results. [=she was not entirely happyorshe was unhappy]
即less than 后接形容词，表示的是不是定意义。
His political analysis is not new, but it could hardly be...
转折连词but提示，他的剖析虽然不新颖，但还是非常有说服力的（雄辩的）。半否定词hardly构成否定意义，还需要一个否定意义，才能构成双重否定，达到一定的成效。所以只能选择less than eloquent.
