每日一句

However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when exposed to it often enough.

詞匯突破

insensitive[ n sens t v]

adj. （對他人的感受）未意識到的，漠不關心的；（對變化）懵然不知的，麻木不仁的；（對某事物）無感覺，無反應

結(jié)構(gòu)分析

本句的主干是 it has been found ...，that 引導主語從句。However 位于句首，表轉(zhuǎn)折。在 that 主語從句中，when 引導的是時間狀語從句，另外，insensitive to a certain smell at first 是定語修飾 people。
