28.The mistakes children make in learning to speak tell linguists more about how they learn language than the correct forms they use.
(A) how they learn language than
(B) how one learns language than
(C) how children learn language than do
(D) learning language than(C)
(E) their language learning than do
In choice A, the pronoun reference is awkward and potentially ambiguous because a plural noun, linguists, comes between they and its noun referent, children.
这里是两个对象比较: mistakes 和the correct forms ,谓语是tell , 中文意思即"孩子所犯的错误比他们用的正确方式更能告诉语言学家他们是如何学习语言的",
比较对象清楚后,就只要用"助动词尽量补出原则" 解题即可, 助动词即do, 所以 than 后面要有do, 而且这里do 不能省略,如果不补, 则变成how they learn language than 和the correct forms they use 两个名词的比较,显然补符合逻辑, 这样 A B D 都可以排除了, 而E根据意思也可以排除. 故此题答案是C;
