OG13 sc53新问题，关于选项中介词

Summer婵

The nineteenth-century chemist Humphry Davy presented the results of his early
experiments in his “Essay on Heat and Light,” a critique of all chemistry since Robert
Boyle as well as a vision of a new chemistry that Davy hoped to found.


A. a critique of all chemistry since Robert Boyle as well as a vision of a
B. a critique of all chemistry following Robert Boyle and also his envisioning of a
C. a critique of all chemistry after Robert Boyle and envisioning as well
D. critiquing all chemistry from Robert Boyle forward and also a vision of
E. critiquing all the chemistry done since Robert Boyle as well as his own envisioning of

这道题考的主要是平行，我对答案没啥疑惑，我就对每个选项中的介词有点疑惑。。。。不知道它们有什么区别？都能这样用嘛？since加个人名？不懂啊。。。。。。。。OG中也没给解释，那就是都没问题？

not sure can help you or not, some comment from oversea website.
To my honest, I also have no idea about since, after, etc.  



It has to be "since". Once we accept that Robert Boyle is important enough to warrant an era named after him, it is pretty clear from the sentence that the author is including the chemistry from that era in the analysis. "since" is the only one of these words that does this..。。。。I think the implication is that Robert Boyle's work and discoveries were so significant that there was an era associated with his work that is known and obvious.

不太同意。我觉得都可以

这里你只要表示出这个critique是写在谁之后就行

浅见，笑纳~
since本质就是个介词，后面是名词性质的成分就行，意思是自从...开始；
following可以是个形容词，也可以是介词，这个题目中介词更好吧~词典中这样说：Subsequent to; after: 随后；在…以后：e.g.:  Following dinner, brandy was served in the study.
正餐后，白兰地酒端进书房内;



from...forward我感觉有些啰嗦，意思好像有些矛盾，本身forward又向前的意思，而这个向前说的是位置上了，用在时间上我不知合适不合适；
after在GMAT中的用法我总结过，我一下找找贴上来~

after的词性可以是副词、介词、连词和形容词；在GMAT中的用法大概分一下几种：
（1）after+名词词组：一般介宾结构，不多说
（2）after+逻辑主语+过去分词：e.g.: after an assembly-line technique introduced by Ransom Olds
（3）after+doing：此时需注意doing的逻辑主语，绝大对数正确情况是单一主语的句子的主语，表示某动作之后，体现动过的先后e.g.: *The results of the company's cost-cutting measures are evident in its profits, which have increased 5 percent during the first 3 months of this year after falling over the last two years.*After suffering $2 billion in losses and 25,000 layoffs, the nation's semiconductor industry, which makes chips that run everything from computers and spy satellites to dishwashers, appears to have made a long-awaited recovery.
（4）after+句子：表示某动作发生时点之后 e.g.: *Less successful after she emigrated to New York than she had been in her native Germany, photographer Lotte Jacobi nevertheless earned a small group of discerning admires, and her photographs were eventually exhibited in prestigious galleries across the United States. *Almost a decade after New York State passed laws to protect patients by reducing the grueling hours worked by medical residents, an investigation of twelve hospitals by state medical officials has found that all twelve consistently break the laws, that many residents work longer than 24 hours straight, and that more than half the surgical residents work more than 95 hours a week. *Initiated on Columbus Day 1992, five centuries after Europeans arrived in the New World, Project SETI pledged a $100 million investment in the search for extraterrestrial intelligence.

能理解以他的名字命名的时代，“it is pretty clear from the sentence that the author is including the chemistry from that era in the analysis.”这句没懂。。。。。。。。。看了楼下的解释，从意义和词性上来看，这些词都是介词并且都是在。。。之后，和名词一起构成介宾结构，表示在RB这个时代之后，那么也就没有问题了哈。就是from。。。。forward怪怪的。。。。
