None of the shoes in the shop fit me well. They are ____ too big ____ too small.
A. both; and B. either; or C. not only; but also D. not; but
B 考查短语辨析。both ... and ... 意为“……和……都……”，表示对连接的两事物进行肯定；either ... or ... 意为“要么……要么……”，表示对连接的两个事物中的一个进行肯定；not only ... but also ... 意为“不但……而且……”，连接两个并列的事物；not ... but ... 意为“不是……而是……”。句意“鞋店里没有一双合适”，说明要么太大，要么太小。故选B。
