Few people paid full attention to their health conditions ________ they were seriously ill.

A．when

B．if

C．until

D．after

答案

C

解析

试题分析：考查连词辨析。A当…时；B如果；C直到…才…；D在…后；本句中的not…until…直到…才…；如果前面的句子使用的短暂性动词，就使用否定句；如果前面的动词是延续性动词就使用until来引导；句意：直到他们生了重病以后他们才会注意到他们的健康状况。故C正确。
点评：此题主要考查连词的辨析，选择连词主要是看前后句的关系，因果关系用表因果的连词，转折关系用转折连词，并列关系用并列连词，要求考生具有一定的句子分析能力和词义辨析能力。
