问题 Biotechnology is supposed to provide more jobs, promote more growth, create better harvest and ______ the Earth many insect-killing chemicals into the bargain.

选项 A、spare
B、make
C、provide
D、furnish

答案A

解析 spare意为“使免遭或免于经历或做(某事)”,本句意为“使地球免于受到多种化学杀虫剂的危害”。类似用法有spare sb.the trouble of doing sth.省去了某人做某事的麻烦。
