问题补充：
It was not until I came here I realized this place was famous for not only its beauty but also its weather.
A. who
B. that
C. where
D. before
答案：
A. who
(答案→)B. that
C. where
D. before
解析：考查强调句型；强调句型的基本结构：It is/was被强调成分that/who其它成分；其最大的特点是把it is/was…that/who去掉，句子仍然成立；本题强调的是时间状语not until I came here.句意：知道我到这里，我才意识到这个地方的出名不仅仅是因为美丽的景色，而且是因为它的气候。故B正确。
