[SC资料] 饺子之RON视频详解——And as connector

"And" creates a parallel structure between elements that are:

    1. *presumed to be independent(unless they are in sequence)

    2. *equal in priority /importance

     eg.I like apples,grapes,and bananas.

     (three separate foods I enjoy with presumably comparable levels of enjoyment)

     特例：We ate dinner,saw a show and (then) went to a club.

     (three sequential events-still pretty much independent--with equal priority)

分析：A truck crashed in front of me on the freeway, and I was late to work.

因为两句都是independent，且用and连接，是并列关系，故I was late for some reason other than the  truck crash.

修改方法：

   1.A truck crashed in front of me on the freeway, making me late to work.

     Comma-ing is to signify a proximate or casual relationship between the main clause and the modifier.

    2.A truck crashed in front of me on the freeway, and I was thus late to work.

      Alone, "and" implies relative independence.

      However, you can pair "and" with other connectors, such as the ones above,to signify this kind of relationship.或者用 so...consequently...

      但如果用hence，一定表明了logical relationship.

Level1

   A.Ron devoured his lunch,crunched loudly, and burped at regular intervals.

   B.Ron devoured his lunch, crunching loudly and burping at regular intervals.

   C.Ron devoured his lunch, gulped down the drinks,and fell asleep.

   D.Ron devoured his lunch, gulping down the drinks and falling asleep.

知识概况：

1.Three separate actions;none of them is prioritized over the others and none is a component of an other one(同等地位时)——need parallel structure.

   (单从形式上考虑A,C为此类情况)

2.Future description of the former one---they should be a modifier  

（单从形式上考虑B,D为此类情况）

BUT you can't judge grammatical structures until you know what message they are intended to convey.

从意思上分析，devour吞食，crunching咯吱咯吱的声音，burping打嗝 后两个是前面devour的解释，所以选用modifier形式；而gulp一大口，fell asleep明显是之后的动作，表示sequence，故选择parallel structure.最后B,C为正确。

ps.you can't have a comma on only one side of a modifier(unless it begins or ends the sentence).

Level2 做题必备

问自己：

What is the intention of the sentence?

Use 2 things:

1.common sense/ real-world thinking

2.The sentence is a unit in the sense that it should convey some sort of unified meaning.,

开始读：

First Read:

*Fast--you are not picking through and trying to find errors.

*get the meaning...including is this parallel?

*if anything is blatant enough that you notice it will reading quickly, then use it to eliminate. If not, wait until you see splits in the answer choices.

例题1 Scientist at the Los Alamos National Laboratory have succeeded for the first time in mining heat from the Earth's interior and producing energy on a commercial scale, enough for efficient generation of electricity and heating factories and homes.

A. and producing energy on a commercial scale, enough for efficient generation of electricity and heating

B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat

C. for energy production on a commercial scale,enough for generating electricity efficiently and to heat

D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating

E. to produce enough energy on a commercial scale for efficient generation of electricity and heat

根据ron学生的一语道破，因为句子中使用了and连接，mining heat has nothing to do with producing energy,也就是说mining heat和producing energy两者是separate的，那么利用common sense真的是这样么？显然并不是，就如同现实中砍树为了造纸一样，这里是有前后联系的，而非像I like apple,banana and pie.中每一个都是相互独立的。（如果习惯用语法做题，很容易掉进陷阱里，即看到scientist  have succeed for the first time in mining and producing...然后还沾沾自喜觉得很不错，然并*）

沿着这个思路，将AB排除，剩余CDE，接下来是时候观察下半句会发现明显的parallelism出现。efficient generation of electricity---heating of homes或者 generating electricity efficiently---heating factories and homes.两者皆可

C. for energy production on a commercial scale,enough for generating electricity efficiently and to heat

D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating  √

E. to produce enough energy on a commercial scale for efficient generation of electricity and heat
