W: John, I don’t really see why humans had to send astronauts into space. Robotics is so much more advanced now, why can’t they simply send robots?
M: Well, robotics has come a long way and it’s more expensive to send a manned spaceship into orbit, but the biggest problem with robots is that they have to be programmed for every possible eventuality.
W: Yes, I suppose you’re right. Robots just can’t react to situations independently the way humans do—they still need us to tell them what to do.
M: That’s right.
Q: Why can’t robots be sent into space instead of humans, according to the speakers?
选项 A、They’ re too costly to send.
B、They’ re too reliant on humans.
C、It’ s too expensive to build robots.
D、It’ s hard to operate them for long enough.
答案B
解析 题目问机器人不能代替人类进入太空的原因。从对话中可知，人类选择送宇航员而不是机器人进入太空的最主要的原因是，机器人在没有为每一种可能性都进行编程的情况下无法独立应对各种情况，故选B。
