问题 One reason for malaria to be widespread now is that ______
Lanzaro is hopeful that in a few years man can ______
选项 A、start to eliminate malaria
B、cure parasitic blood diseases
C、prevent mice from transmitting parasites
D、acquire immunity against malaria
答案A
解析 第二段大意：Lanzaro和他的同事们计划在五年内生产㈩抗疟疾的蚊虫。现在他们已经成功地制造出不能向鸟类和鼠类传播疟疾的基因工程蚊虫，接下来科学家们会尽快研究出能阻止疟疾向人类传播的基因。其隐含意思是人类在几年后消除疟疾是大有希望的。其他三项为干扰项。
