选项 _________(51)A:diagnoseB:increaseC:examineD:treat
答案B
解析由前后两句的转折关系可知，抽烟不是减轻忧郁，而是加重（increase）了忧郁的症状。 由第五段的最后一句话中的“emotional benefits”可知选emotional合适。 由前后两句语境可知此处表示转折关系，四个关联词只有B项合适。 in the long term意为“长期”，为固定搭配。 抽烟只能影响（affect）情绪，而不是其他的反应。 schools located意为“学校坐落在……”，其他选项不符合句意。 由下文可知，参加者是被分成三组（groups)。 mood or physical state意为“精神或身体状况”，为常用搭配。 have trouble doing sth.意为“做……有困难”，为固定短语。 mood improver意为“情绪改善者”，符合语境。 由前面的“higher”可知此处是比较级，所以用than。 at risk为固定词组，意为“有风险”;at higher risk意为“有更大的风险”。 在忧郁和抽烟之间只有“联系”(association)，而不是“合作”、“不同”与“一致”。 这种抽烟和忧郁的联系主要存在于抽烟感觉好的青少年中，由句意知选B。 由动词不定式后面强调的内容可知，此处是强调其重要性，所以选A。
