题目

1,Secondly,people should be educated to distinguish the right from the wrong.的句子中为什么要用“from”?
2,……if they are of great help.为什么要用“of”?
3,“As is indicated in the above picture,”能去掉“is”吗?我见有的句子就没有“is”啊?例如：As depicted in the picture,……
4,Once used to describe the copying of electronic products ,the catchphrase has now been applied to the cloning of everything that is popular,……的句子中“now”能不能放在has前面?为什么要放到那个地方?“that”指代的什么?是什么成分?
5,……,I am convinced that under no circumstances is Shanzhai(山寨) culture going to replace what it imitates.的句子中“under no circumstances 山寨文化为什么插在“is going to”中间?

答案

1.固定搭配 distinguish A from B,意思是“辨别A与B”.
而 distinguish the right from the wrong 辨别是非
2.固定短语 be of great help = be very helpful
如果没有of,则句子主语they和help无法对应：他们是帮助?
3.两种都可以,句意基本相同,但是用法不同.
As is indicated in the above picture是定语从句,关系代词as代指后面的主句,在此从句中充当主语；
As depicted in the picture是状语从句,且从句省略主语和be动词,即 = As (主句主语 + be动词) + depicted in the picture
4.now这种副词的位置非常灵活,但是如果放在句中,则一般放在所谓的be动词/情态动词/助动词之后,行为动词之前,此题刚好放在助动词has和been中间.
that为定语从句的关系代词,代指先行词the cloning或everything（因为楼主后面的从句没有打全,无法准确判断）.
5.under no circumstances意思是“（在任何情况下）都不/决不”,在that从句中充当状语.
含否定词(比如no)的状语短语至于句首时,该句必须采用部分倒装语法,即把该句的be动词/情态动词/助动词提前到主语之前.
即：under no circumstances is Shanzhai(山寨) culture going to replace what it imitates
= Shanzhai(山寨) culture (is) going to replace what it imitates (under no circumstances)
再如：In no case will I give up.
= I will give up in no case.
我决不会放弃.
