GWD 6-30，请NN指点

Though subject to the same wild-animal control efforts that killed off almost all the wolves in North America over the past century, the coyote’s amazing ability of adapting to the presence of humans has enabled it to expend its range into Alaska and Central America.

答案是C，这句话前半句不明白什么意思，为什么选C啊？我选E.请NN指点！

帮你顶。

加上我的问题：A是不是因为it的指代不明——可以指coyote,也可指ability,而错？

haha , i am not NN.

A 的错误是代词"it or they" 不能指代名词所有格。名词所有格转换成 a of b. is better.

in D and E, the subject is "coyote", not "amazing ability of the coyote "

also, "ability to"  , normally don't insert any word between "ability" and "to"

Though subject to the same wild-animal control efforts that killed off almost all the wolves in North America over the past century,

在上一世纪，尽管受一个相同的野生动物所限的环境，这种野生动物杀死了几乎所有在北美的狼。就是说所有的狼的敌人是这种野生动物。生存环境比较恶劣。

A     coyote’s amazing ability of adapting to the presence of humans has enabled it to expend its

1）  ability ---   enabled  ---语意重复 能力使他能够，啰嗦。

2）  it 指coyote’s amazing ability 也就是说指能力，coyote’s  后面有’s，所以是修饰成份，修饰ability，文中是想指coyote

這題考點是:  從句之主詞是否與主要子句之主詞一致, 2秒內即可知道不是B就是C

(首句從句或形容詞子句)...subject to the same wild-animal control efforts, ....->試問:是誰遭受到控制呢? 從這句省略的主語妳可猜主要子句的主語應是"有生命"的動物, 所以 A. coyote’s amazing ability 及D.E.amazing ability   都不會從句的主語, 應為ability不會遭受到..的控制

再者, ability of doing 是常見的英語錯誤用法, 應改為ability to do.(Longman Dictionary of COMMON ERRORS)

主句的主语与subject to逻辑关系是否正确

然后看ability to do
