B.those

C.these

D.them

248.This design is _______ satisfactory.So you'll have to try your best to better it.

A.nothing but

B.anything but

C.all but

D.something but

答案解析

247.答案是B；此处指代the desks,为特指。

248.答案是B;考查不定代词与介词but的搭配。Nothing but=only 仅仅，只不过；anything but 除…以为的任何事物，根本不；all but 几乎不，差一点。根据you'll have to try your best to better it暗示，此项设计绝不令人满意。
