不仅要答案 请给出这么选择的原因~

Answer 1

1 A 因为unlikely是不太可能的意思，unfriendly 是不友好的意思，forbidden是禁止，vulnerable
是易受伤的，这句话的意思是科学家发现的很多星球都不太可能让人类居住，unlikely符合意思，而且unlikely是与to搭配的，符合语法。
2 D be exposed to 的主语应是人，是暴露的意思，不符合，commute减少，migrate人搬迁，都不符合，只有transfer转移符合这句话的意思。
3 A 因为此句的连词是and，是承接关系，故应该是汽车，火车，飞机，越来越多，故排除了其他3个选项。
