问题 This is an alarming realization as natural resources and the environment are being degraded and______at a record pace.
选项 A、wasted
B、reconstructed
C、destructed
D、reversed
答案C
解析 四个单词的意思分别是waste“浪费”；reconstruct“重建”；destruct“破坏”；reverse“撤销，废除”。句意是：人们吃惊地认识到，自然资源正在以前所未有的速度在被消耗掉，环境也在日益恶化，处处受到破坏。所以正确答案是C选项，如The engineers had to destruct the rocket for safety reasons(为了安全原因，工程师们不得不毁掉火箭)。
