Question

关于英语语法结构？

Having seen the trial-and-error procedure for finding the optimal point (2, 6), you now can streamline this approach for other problems

分析第一句的having seen从句

Answer 1

回答：本句是简单句，无从句，其结构是：（现在分词短语作）时间状语（Having seen…point，相当于After having seen…，其中的for finding…是定语）+主语（you）+时间状语（now）+谓语（can streamline）+宾语（this approach）+目的状语（for other problems）。
翻译：当你目睹了这一寻求优化的试错法之后，你现在就可以将这一简化的方法应用到其他问题上。

Answer 2

就问卷调查而言，我并不是想把它仅局限于某个特定的点，而是想要尽可能包括不同的类型。 With the questionnaire, rather than limiting it to one specific point, I wanted to include as much variety as possible. rather than 意为 “而非,而不是” 。是个万能插入语。具体语法点你可以去找些语法书看。判断插入语的标志：双逗号，双破折号。（一般都是这样子的） as ... as possible 意为 “尽可能...” , 如 :as soon as possible 意为“尽快”可简写为ASAP; as much/many as possible 意为“尽可能的多”
