The confusion of costs with rates persists partly because labor rates are a convenient target for managers who want to make an impact on their company's budgets. Because labor rates are highly visible, managers can easily compare their company's rates with those of competitors.

the major problem with (d) is the incorrect construction "of + NOUN + VERBing".
also, it's unidiomatic to say that a RATE is "half" (or "more/less than half"). you could say that a rate is 50%, but not "half".

什么时候现在分词做伴随状语可以就近修饰了？不是说一定要找主句的主语么？

错选d，80 percent of the time.原文没有题，不要脑补，这种几乎一定错

A里面for不对的原因是不是应该是，for通常表示目的，而这里是需要进一步阐释evidence的内容，所以应该用that从句呢？

contradictory accounts 矛盾的

innovation. 创新。。。。没看清

定位，第一句

D选项的解释应该有误，这里and不一定错，可以是表示前一句的延伸，刚好接上解释population。

and的平行可以先排除掉一些选项，需要对基本考点敏感

Thus a woman who views the Second World War as pivotal in increasing the social acceptance of women’s paid work outside the home may reach that conclusion partly and unwittingly because of wartime rhetoric encouraging a positive view of women’s participation in such work. 老师你好我看了很多遍这句话，也查了翻译。还是不知道如何联系上下文理解这句话。你可不可以帮我在解释一下， 非常感谢

C: so that是目的状语从句吧？

这个题D还是挺tricky的，自认为认真读文章的我差点选了D，但实际上文中还提到了shake violently under anesthesia. 而neuroscientist关注的是nerve system，所以是感兴趣的。

BD认真看的话其实都可以排除，因为escape velocity并不是形容那些速度。 这里引入EV是为了接下来的解释，低于EV的会聚在一起，高于EV的会离开（这也解释了为什么小行星撞击后是singular，而大行星撞击后会聚集复原）

C选项还是有点不明白

错误原因：没有认真transfer原文和选项： 错选D：concerned about its potential to impede the implementation of new technologies. 这里并不是concern 'it will impede the implementation' 而是“have a decisive influence on...” or "can be a primary determinant ...“， 即是怕其影响technology的壮大发展而不是影响新科技的implementation

实际上整篇文章就是在question第一段那些environmentalist得出的结论，就是E选项。

If you say \"when + PAST PARTICIPLE\", then this automatically applies to the SUBJECT of the clause to which it\'s attached.

if i say
iron accumulates rust when submerged in water
then it\'s the iron, not the rust, that\'s submerged in water.

this strikes choice (d), since the SUBJECT is \"recently documented examples\", not \"mice\" as required.

idiom: be immune to

选项E：brightening作为伴随状语修饰was triggered by也是有问题的吧？brighten的主语就变成了a large storm.在正确选项C里面伴随状语brightening和knocking的主语都是an expanding cloud of energized particles
