Answer 1

【答案】to imagine；have lived；haven't been；that；hobbies
【解析】①考查固定句型 It's +adj. + for sb to do sth，意为“对某人来说……”，故填 to imagine。意思是：对我们来说很难想象。
②根据后面的时间段 for so many years 可知用现在完成时，故填 have lived。意思是：人们在地球上已经生存了这么多年了。
③根据句子的状语 yet so far可知用现在完成时，故填 haven't been。意思是：到目前为止人们还没有去过火星。
④比较的是火星和地球上的生活 （life），life意为“生命”时是可数名词，有复数形式 lives，但是意为“生活”时不可数，故填 that。意思是：我认为在很多方面火星上的生活会比地球上的生活好多了。
⑤hobby是可数名词，此处用其复数形式 hobbies。句意是：所以人们会有更多的时间来从事他们的业余爱好。
