问题
Researchers discovered that plants infected with a virus give off a gas that______disease resistance in neighboring plants.
选项
A、contracts
B、activates
C、maintains
D、prescribes
答案
B
解析
所填词需与disease resistance“抗病性”搭配,将[A]contract“感染”与[D]prescribe“开处方”先排除:[B]activates“激活、活化”与[C]maintains“保持”,发出的气体只能是“激活”抗病体而不是“保持”,所以答案为[B]。
