问题 So little ______ about China that ho could not find Beijing in the world map.

选项 A、the foreigner knew
B、did the foreigner know
C、the foreigner has known
D、has the foreigner known

答案 B

解析 本题考查的是谓语动词时态前后一致和倒装句的用法。本句是主从复合句,后面从句的谓语动词could not find为一般过去时,根据谓语动词时态前后一致的原则,前面主句的谓语动词know的时态也应为一般过去时;“so+形容词/副词”放在句首加强语气时,主句中的主谓语必须要倒装。即使用“助动词+主语+谓语动词原形”的结构。故选项B为正确答案。A项“the foreigner knew”和C项“the foreigner has known”均未实现主谓倒装;D项“has the foreigner known”是动词的现在完成时形式,与后面从句的could not find在时态上不一致。故此三项皆应排除。
