选择题
Spring Festival is the most important festival in China and an occasion ____ all family members get together, just like Christmas in the West.
A．where
B．when
C．that
D．which
答案
答案：B
考查定语从句。定语从句all family members get together修饰先行词occasion。这个定语从句结构很完整，所以使用关系副词，本题的occasion是指时间，所以用when。句意：在中国春节是最重要的节日和全家团聚的时刻，就像西方的圣诞节一样。
