another, the other, other; where, which, in that Scientists believe that life on _________ planets was just a hopeful dream. But now they are beginning to locate places _________ life could form.
【正确答案】:other,where
【题目解析】:同义词区分,another表示再一个,又一个,the other 指的是两个中的另外一个,other的意思是其他的,这个句子的题干部分,提示科学家相信其他星球上的生命,因此other是合适的选项。第二个空格的地方是关系从句的开始,引导词做状语,所以选择where。
