Meteorite explosions in the Earth’s atmosphere as large as the one that destroyed forests in Siberia, with approximately the force of a twelve-megaton nuclear blast, occur about once a century. The response of highly automated systems controlled by complex computer programs to unexpectedcircumstances is unpredictable.
大家看我这样的理解对不对,
关于E选项为什么要加后面那一句是因为The response of highly automated systems controlled by complex computer programs to unexpectedcircumstances is unpredictable.也就是说系统对于unexpected的事务是unpredictable的。如果没有加后面那一句,那么前半部分不能成立。
E. It is not certain what the system’s response to the explosion of a large meteorite would be, if its designers did not plan for such a contingency.
我一开始选的是A,现在知道E一定对。但是还是没最后清楚OG对A,C的解释 |
