问题 Houseflies that hatch in summer live only about three weeks, but those that emerge in the cooler days of fall often live longer than six months.
选项 A、weeks, but those that emerge in the cooler days of fall often live
B、weeks, but those that emerge in the cooler days of fall often live as long or
C、weeks, which is different from those that emerge in the cooler days of fall and often live
D、weeks, then those that emerge in the cooler days of fall often live as long as or
E、weeks, this is different from those that emerge in the cooler days of fall, who often live
答案 A
解析 B中as long结构不完整，还缺一个as，D中连接副词then意思不对。E中：this指代有问题，在GMAT中就不用单独的this作指代词。who指代物体不恰当。C的表达啰嗦，且which从句离其先行词太远。
