大家帮帮忙哦(已解决)

         sulfur dioxide, a major contuibutor to acid rain ,is an especially serious pollutant because it diminishes the respriatory system's ability to deal with all other pollutants

       A, an especially serious pollutant because it diminishes the respriatory system's ability to deal

       B.an especially serious pollutant because of diminishing the respriatory system's capability of dealing

我只写了A,B  答案是B，

我问一下，A的错误是不是it指代不明确？还有该如何判断because of 的从句修饰哪个成份？

最后问一下especially 和specially的区别是什么？请大家指点

A的错误是不是it指代不明确？还有该如何判断because of 的从句修饰哪个成份？

我觉得是指代不明.because of 的从句我觉得不是修饰一个成份,而是解释整个前面的句子(或者说是谓语本身,而不应该是修饰一个成分).

简单地举个例子:

他(昨天晚上)病(得很严重),因为他淋雨了.淋雨是解释他"病"谓语,而不是状语昨天晚上,也不是解释很严重.

especially 和specially的区别我的理解,不见得准确,欢迎指正)

especially 是尤其地,特别地,我不知道你是否能体会"尤其"这个词的意思,呵呵,我好象有点说不清.

specially是特别地.建议翻翻语法书,张道真的那本好象有解释.

回答如下：

special比especial更为常用，具体意思这里不解释了，反正一般都是special

especially常用于+adj，表示特别的怎么

specially 常用于某个行动专门为了什么目的

especially+N，表示某某特别怎么怎么，specially + N不大看到

这里应该用especially

这题答案是B？肯定吗？我一直认为是A呢

it没有指不明啊，amajor contributor to acid rain是同位语解释sulfur dioxide,所以it指的就是sulfur dioxide。

我选A的主要理由是ability和capability，前者是能力，后者是容量

回楼上，我的这本书上答案是B

ability和capability都可以表示能力，用法是ability to do/capability of doing/capability to do

回四楼，大概明白了，谢谢这里所有人给我的帮助

补充一个刚才查到的国外sepcially and especially的解答

Especially
        or
        Specially?

This is a favorite question of grammar checkers. Most of the time there is little or no difference between the words especially and specially.

Special is a common adjective. Specially is its adverb form. Special means "particular, distinguished in a distinct way, or designed for a particular purpose." Specially means "particularly, in a disintguishing manner, or for a particular purpose."

Especial is an uncommon adjective. Especially, its adverb form, is much more common. Especial means "exceptional, noteworthy, or particular." Especially means "exceptionally, in a noteworthy manner, or particularly."

In the sense of "particular" or "particularly," the words mean pretty much the same thing. Often they can be used synonymously. However, if you want to stress the exceptional or noteworthy quality, then especial or especially is a better choice. If you want to stress the distinctive purpose of something, then special or specially is the word you are looking for.

Example: This program has specially designed macros for word processors.
(A distinctive purpose)

Example: He did especially well in All-Star Game.
(A noteworthy performance)
