34.A wildlife expert predicts that the reintroduction of the caribou into northern Minnesota would fail if the density of the timber wolf population in that region is more numerous than one wolf for every 39 square miles.
(A) would fail if the density of the timber wolf population in that region is more numerous than
(B) would fail provided the density of the timber wolf population in that region is more than
(D) will fail if the density of the timber wolf population in that region is greater than

    答案是D，没问题。
    排除A，B时，只是觉得would不爽，但是找不到理论上的支持，请教牛牛

同意。WOULD用在这里是不怎么好。
D选项就是ETS非常喜欢的
B will do if A happens.
搭配。

又发现一个问题：先补充一下该题目的选项
(C) should fail if the timber wolf density in that region was greater than
(E) will fail if the timber wolf density in that region were more numerous than

    这里的the timber wolf density 肯定是错的，应该是the density of the timber wolf population 。前面有类似的问题，如大全2

2.A 1972 agreement between Canada and the United States （（reduced the amount of phosphates that municipalities had been allowed to dump）） into the Great Lakes.
(A) reduced the amount of phosphates that municipalities had been allowed to dump
(B) reduced the phosphate amount that municipalities had been dumping
(C) reduces the phosphate amount municipalities have been allowed to dump
(D) reduced the amount of phosphates that municipalities are allowed to dump
(E) reduces the amount of phosphates allowed for dumping by municipalities

这里的B，C选项中the phosphate amount 肯定也是错的。

当时有个牛人指点说：牛人指点：the phosphate amount 这种修饰是不清晰的，ETS一象是这样认为的，比如说the population change就不行，the change in population是可以的

那么是不是可以这么认为，在ETS的SC中，名词修饰名词不可以接受呢？？？？

我觉得

至少 象 population, amount, density 一类的名词 不能由其它名词 直接修饰

而 要用 the population/ amount /density of  + 其它名词

dreadpower

能否归类这些名词呢》？？或者说什么样的名词可以由名词修饰，什么样的名词不可以？

dreadpower

有没有大牛能回答这个问题啊？？？

dreadpower

？？？？

再加一个

a species of  large crab  优于  a large crab species

(a large crab species 有歧义: large 修饰 crab or species)

窃以为不是would不爽，要用其实would也可以，只是后面的is要改成were，虚拟语气。当然will。。。is也是最普通的形式，但是这个地方千万不能出现would。。is，或者will。。was之类的不伦不类的形式。一点浅见，请赐教
