    Though ____ the dangers of smoking to their health, smokers still find it hard to give up smoking.
    A．awareB．aware ofC．are aware ofD．be aware of
    B

    试题分析：考查状语从句的省略：句意：虽然很多经常吸烟的人已经意识到抽烟对他们健康造成了很严重的后果，但是他们仍然发现很难戒烟。Though引导的让步状语从句是省略句，完整的句子是：though smokers are aware of the dangers of smoking to their health。当主从句的主语一致的时候，可以省略从句的主语和be动词，选B。
