楼主的高分究竟是多少分阿~
第一题：
Twenty-two feet long and 10 feet in diameter,the AM-1 is one of the many new satellites that is a part of 15 years effort of subjecting the interactions of Earth’s atmosphere,oceans,and land surfaces to detailed scrutiny from space.
提取主干大意：
satellites is part of 15 years effort of subjecting the interactions of Earth’s ……
of subjecting = to subject
因此选E
第40题
推理过程如下：
1、strains of bacteria from different planets would probably have substantial differences in protein structure that would persist over time 两个星球上起源的细菌构造极为不同,而且长时间后也不会同化
2、no two bacterial strains on Earth are different enough to have arisen on different planets 地球上现在所有的细菌看上去都不可能是起源于不同的星球
3、文章的推论是：即时火星上的细菌来到了地球,也应该全死光了
推理：地球上现在的细菌既然是起源于同一星球的,而细菌又有可能从火星移植过来地球,那么--〉可能现在地球上现存的细菌都是火星细菌的后代咯
因此选D
D.It fails to consider whether all bacteria now on Earth could have arisen from transported Martian bacteria.
