问题 So little ______ about China that he 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—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。
