问题描述：
I believe that the is unlikely to be the only planet___life has developed gradually.
A that B where C which D whose
还有关于地点状语从句 where与that 的辨析
答
少了个earth吧，这题应该选A,因为 句中the earth虽然是主语，life has developed gradually是修饰强调句型"the only“ planet的。
答
B
定语从句
引导词where在从句中作状语
答
B 定语从句恢复成完整的句子应该是life has developed gradually on the planet 前面缺了介词on 故用where,也就是说前面一部分缺少介词的一般就要用where.另外需注意,定语从句中有only后面就只能用that而不能用which
