A解析試題分析：句意:你聽說過嗎？消防戰(zhàn)士沖進燃燒的房子，其中的三人不幸被困住了，失去了生命。這里是獨立主格結(jié)構(gòu)，three of them與catch是被動關(guān)系，故用過去分詞；three of them與lose之間是主動關(guān)系，故用現(xiàn)在分詞，故選A�？键c：考查獨立主格結(jié)構(gòu)的用法。點評：本題難度適中。獨立主格結(jié)構(gòu)是高中的難點，近幾年考得次數(shù)較少，需要考生有分析理解復(fù)雜的句子結(jié)構(gòu)的能力，還必須能夠理解句意。即學(xué)即練：The thief fell to the ground, his left foot _____ and blood _____ down from his mouth.A. breaking; running B. broken; runningC. breaking; run D. broken; run解析：B。句意：考查獨立主格結(jié)構(gòu)。foot和break之間是被動關(guān)系，blood和run是主動關(guān)系。
