问题 Bufo marinus toads, fierce predators that will eat frogs lizards, and even small birds, are native to South America but were introduced into Florida during the 1930’s in an attempt to control pests in the state’s vast sugarcane fields.
选项 A、are native to South America but were introduced into Florida during the 1930’s in an attempt to control
B、are native in South America but were introduced into Florida during the 1930’s as attempts to control
C、are natives of South America but were introduced into Florida during the 1930’s in an attempt at controlling
D、had been native to South America but were introduced to Florida during the 1930’s as an attempt at controlling
E、had been natives of South America but were introduced to Florida during the 1930’s as attempts at controlling
答案 A
解析 由attempt一般由动词不定式修饰的规律，就可排除C、D、E。B中：as attempts的用法不妥；同时native之后一般跟介词to而不是in。本题还可换一套解题办法：由native to的习惯用法，可排除B、C、E。再比较A、D，即由attempt的用法可得到正确答案A。
