选择题
__ it to clear up tomorrow, the tourists would climb to the top of the mountain to see the sun __.
A．If; to raise
B．Were; rise
C．Should; rise
D．If; raising
答案
答案：B
题目分析：句意：如果明天放晴，游客会爬到山顶看日出。从主句would climb可知这里是虚拟语气，if条件句可以用省略倒装，因为句中用to，所以是和将来相反的情况，用were to do，were可以提前，省略if，第二空用see +宾语+省略to的不定式，表示看见…做了，选B。
