答案:

B

提问:

正确答案B,我选的C选项,听以前的录音说which指代有歧义?不大明白~老师可不可以系统讲一下which在定从的指代~~ 另:如果选B,没有体现出while前后语义的对称呀?通过语义我感觉是improve和introduce并列,所以选的C。难道该句是introduce与improve两个动词表示顺承关系?那while应该如何理解呢?希望老师指正~~

提问:

此题中,关于是谁不加控制的增长在50年前,对于这个修饰最明确的的确是B选项让人一看就明白是生物污染不加控制的生长,但是while作为一个连词是连接句子的,既然有了while为什么不能将B以句子残缺排除呢(它没有动作发起者也没有一个动词,只有ing形式)?这样就剩下A,C了。我这个思路哪里出了问题呢?请老师点出。谢谢!
