What is even more important is_____ the earth cooled down, water began to appear on its surface. 
A．that B．that as C．which D．which as
B

試題分析:考查名詞性從句。根據(jù)結(jié)構(gòu)可知is 后面是表語(yǔ)從句，表語(yǔ)從句中又有狀語(yǔ)從句，所以需要兩個(gè)連接詞，一個(gè)引導(dǎo)表語(yǔ)從句，一個(gè)引導(dǎo)狀語(yǔ)從句。which引導(dǎo)從句需做成分，而表語(yǔ)從句中不缺少成分，所以B選項(xiàng)正確。句意：甚至更重要的是當(dāng)?shù)厍蚶鋮s的時(shí)候，水開始在地球表面上出現(xiàn)了。
