2.A细节判断题。根据文章第一句话可知,JohnGrunsfeld认为火星上可能存在咸水。

3.B推理判断题。根据第七段的说明可知,火星上水的源头还是个谜。

4.B推理判断题。根据第五、六两段内容,火星上的天气有利于水的存在。

B

5.C细节推断题。根据第一段最后两句和第二段的第一句可知答案。

6.D代词指代题。根据第三、四段说明可知,有些科学家害怕来自于外星人的回复可

能不那么友好,因而表示了对这个计划的不赞同,此段说明霍金教授也在其中,故those指

的是反对这个计划的科学家们。

7.D细节推断题。根据倒数第二段最后一句ProfessorStephenHawking所说的话可知,

他警告说:如果外星人访问我们,后果也不好,也会像哥伦布到达美洲时对土著美洲人那
