B 不知道like现在让不让用于举例… 让的话也不如A简洁
C 没有so much…but的用法，应该是“否定...so much as”；as simple as后面应该接名词结构而不是一个when…， when…从句 一般是verb modifier，不能做为名词结构； when..和后边的anxiety or stress不平行
D 没有so much…but的用法；明明同一个主语，就不用再单拎出来一个it了；maybe不正式，不应该用于书面英语；certain medications和后面的anxiety stress意思不平行
E 没有so much…but的用法；maybe不正式，不应该用于书面英语
C①had been overcome的时态和没划线部分的time-maker in the mid-1970's不对应，而且和它平行结构对应的fell也不对应（像是意思是说鸟一fell他们被污染影响的这个事情就终止了一样）②a plan that..同A
D correct
E①意思变成了鸟促使官方咋地...但是其实应该是鸟被影响还掉下来这件事促使的 ②were prompting没有justify过去进行时这个时态的理由
A ①in the mid-1970's在句子开头，接下来应该是independent clause，而不能是从句since… ②birds were routinely falling from sky 意思好像是同一只鸟在一遍又一遍地往下掉，但是一只鸟只能掉一次，所以用fell更好 ③this不能单独出现充当名词结构，指代不清 ④plans that reduced意思是官方推行这个plan的时候plan已经减少了排放，逻辑错误
B①同A in the mid-1970's在句子开头，接下来应该是independent clause，而不能是从句since… ②that had been overcome其实可以直接写成overcome，不够简洁 ③在介词结构中的名词不能作为主句主语代词的指代对象，所以it不能指代sky或者pollution，即使可以意思也不对
- 'transferring... occurs' is bad idiom (you can't use occurs with the gerund form)
- the 'it' toward the end of this choice is technically ambiguous (could theoretically refer to 'transferring' or 'ocean', or perhaps even 'air')
The paleontologists found some fossils and on the basis of this discovery, they announced these dinosaurs were at least 25 million years older than any other similar type previously found in North America. Hence, these two actions are not independent of each other. There is a causal relationship here. Hence, presenting these two information as two independent entities in a parallel list does not make sense.
(d) and (e) also misuse "when". you cannot use "when" unless you are literally talking about the timeframe in which an event takes place.
according to (d) and (e), these savings are only realized when someone is actually making the comparison. (i.e., only when someone else is looking at the statistics, comparing them, do these people actually save money!)
if you see the form "NOUN + prepositional phrase + VERB", then the singular/plural form of the verb is determined by the NOUN. the prepositional phrase is just an intervening modifier, which has zero effect on the grammar of the noun+verb.
the only exception occurs when the NOUN indicates some sort of proportion or fraction.
this sentence is about the AVERAGE global warming over a certain period. so, any sentence containing "from... to..." would be nonsense.
an average is a single value.
