{01}A housing bubble is an economic situation _____ occurs when house prices rise much too fast.
A.which
B.where
C.what
D.why
解析: 试题分析:考查定语从句。从结构判断situation为先行词,后面跟定语从句,从句中缺少主语,所以用关系代词which。B,D选项是关系副词,在从句中不做主语,C选项what不引导定语从句。句意:房地产泡沫是一种经济形势,这种经济形势只有当房价上升太快的时候才会发生。所以A选项正确。 本题选A。 {02}I’m supremely fortunate my parents gave me an upbringing _______ prepared me for the life most of us must now live.
