问题 The mosquito genocide is beginning. Millions of genetically modified

选项 A、versions of the useful
B、vampire insects are being prepared for release in Brazil. If all goes according to plan, the mosquitoes will have a huge sex
C、party and begin to kill off
D、all of their natural counterparts.

答案B

解析 useful改成harmful。vampire insects(吸血昆虫)吸血骚扰、传播疾病,严重影响人们的生活,同时也给家畜和野生动物生长带来不利影响,因此吸血昆虫是“有害的”,故[B]项useful不正确,应改为harmful。句意为:蚊虫种族灭绝就要开始了。巴西正准备释放数百万经过转基因的有害吸血昆虫。如果一切能按照计划顺利进行,那么这些蚊虫将会在一场极大的性派对上杀死它们所有的同伴。
