....lz, 你这个没有划线，让我想了20分钟......

At least two problems with B).


1. "had been", wrong verb tense. "In the mid-1970" suggests simple past tense.


2. "it" has no referent.


Please underline next time =)

真是抱歉
發完之後才注意到線沒有跟著複製過來
謝謝NN的勞動
我當初是想had是表示發生在過去某事之前
所以我翻譯成以前可以克服廢氣的鳥現在會薰暈掉下來
這個概念不能用在這裡嗎?
B錯另一個原因是不是不該用be...ing?

不好意思，我对这些时态的中文单词搞不清楚，所以我用英文来说吧。

In generally, use simple past tense if possible. For instance, you will say,
"Yesterday, I found out that Dinosaurs lived on Earth for 3 million years" (sorry that I made up the number....)

Use past perfect tense ONLY if you need to emphasis the sequence of the action.
"Yesterday, I found out that Dinosaurs had lived on Earth for 3 million years before they died out."
Here, you wanna to emphasize the sequence of two actions, namely "had lived" and "died out."

In the absence of other better choices, you may use "had".

B太wordy了，还有其他错误，
1）were routinely falling这个过去进行时用的没有根据，而且原文只不过是陈述过去的一件事
2）后面的it 指代错误，没有单数名词可以去指代，指bird也不对，因为原文是birds（复数），而且即使是单数，逻辑也不对，不能说鸟去促进政府官员提出方案，D的现在分词promoting修饰前面的句子才是正确的使用方法

但是此题overcome by pollution 和 fell from the sky 不是也应该有先后关系么？应该是先overcome...,再 fell from the sky. 所以觉得正是应该用完成时态来表示这个时间的先后性呀。
