问题
选择题
I’d like to start my own business next year – that’s _________ I will face my big challenge in life.
A．why
B．when
C．which
D．what
答案
答案：B
题目分析：考查从句，从句I will face my big challenge in life不缺少成份，所以引导词在关系副词里选择，先行词是next year，所以是when，所以选B
点评：从句是常考内容，做从句题时，首先看从句是否缺少成份，如果缺少成份，引导词就在关系代词里选择；如果不缺少成份，引导词在关系副词里选择
