问题 There has been a 30 to 40 fold increase in the incidence of malaria caused by increasing mosquito resistance against pesticides.
选项 A、increase in the incidence of malaria caused by increasing mosquito resistance against
B、increase in the incidence of malaria because of increasing resistance of mosquitoes to
C、increasing malaria incidence because of increasing resistance of mosquito to
D、incidence of malaria increase caused by increasing mosquito resistance against
E、incidence of malaria increase because of increased mosquito resistance to
答案B
解析 根据习惯表达a increase in sth．，就可以马上排除C、D、E。其次，如果考生又知道resistance to sth．这种习惯搭配的话，就可以马上选出答案B。但A、B除了against和to的差异外，更大的差异在于：A中的caused by短语被改成了because of介词短语，为什么?在A中，由于caused by紧跟the incidence of malaria，可译为“疟疾的发病率是由日益增长的蚊子抗药性造成的”，歪曲了句子原意。而原句要表达的是：疟疾发病率的增加是由于日益增长的蚊子的抗药性。而B用because of短语作原因状语，修饰整个句子，修正了A中的这一错误。
