The typical teenage lifestyle is already filled with so much competition that it would be wise to plan activities in which there are more winners than losers.

02译文

青少年典型的生活方式已经充满了竞争，因此设计一些优胜者多于失败者的活动是明智的。

03点睛

句中包含so…that...的结构，表示“太…以至于/以致”。it为that引导的结果状语从句的形式主语，不定式结构to plan...为真正的主语。which引导的是以activities为先行词的定语从句，其中more…than…是典型的比较结构。be filled with意为“充满”。
