第一题
More than 30 years ago Dr. Barbara McClintock, the Nobel Prize winner, reported that genes can "jump," as pearls moving mysteriously from one necklace to another.

• Aas pearls moving mysteriously from one necklace to another
• Blike pearls moving mysteriously from one necklace to another
• Cas pearls do that move mysteriously from one necklace to others
• Dlike pearls do that move mysteriously from one necklace to others
• Eas do pearls that move mysteriously from one necklace to some other one
  
  

第二题

More than one hundred years ago, students of ornithology reported that hummingbirds can hoveras insects flitting gracefully from one flower to another.

• Aas insects flitting gracefully from one flower to another
• Blike insects flitting gracefully from one flower to another
• Cas insects do that flit gracefully from one flower to others
• Dlike insects do that flit gracefully from one flower to others
• Eas do insects that flit gracefully from one flower to some other one

B  like后面不是说结构要简单么。。。。。  我想选R  但是E最后真的惨不忍睹

like后面不能跟句子，但这两个题的B like后面都不是句子啊

like pearls moving mysteriously from one necklace to another ：moving 是现在分词做后置定语，修饰pearls

关于like与as的区别，我给你复制一下Manhattan SC分册的讲解：

Like meanssimilarto or in a manner similar to. A prepositionalphrase with like can modify a noun or a verb, creatinga comparison. Only Nouns or Pronouns can follow like.

As iseither a conjunction or a preposition.

1. as作为连词

Conjunction Asappears with a Clause. It has threeuses:

• ·        Duration As: AS I strolled to the store, I smelled the air. (=while, during)
• ·        Causation As: I will not tell you, AS you already know. (=since, because)
• ·        Comparison As: You should walk AS she wants you to. (= in thesame way)
  

Comparison As isthe most important Conjunction use of as on the GMAT. It sometimes appearstogether with just,so, or even so too.

• ·        JUST AS the trains were late yesterday, thebuses are late today.
• ·        JUST AS the trains were late yesterday, SO TOOare they late today.
  

Comparison As canalso appear with a phrase, rather than a full Clause.

• ·        AS in the previous case, the judge took an earlybreak.
  

2. 介词as

Preposition Asis used with a Noun or Noun phrase. It also has three uses:

• ·        Function As: AS your leader, I am in charge. (= in the role o0
• ·        Equation As: I think of you AS my friend. (=you are my friend)
• ·        Stage As: AS a child, I thought I could fly. (= when I was)
  

In any ofthese prepositional senses, As does not mean “similar to.”

• ·        I will jump up LIKE a clown. (= in a clownishmanner)
• ·        I will jump up AS a clown. (= in a clown suit)
  

To forcethe Comparison As meaning, use a clause (include a verb).

• ·        I will jump up AS a clown MIGHT. (= like ahypothetical clown)
• ·        I will jump up AS clowns DO. (= like actualclowns)
  

The structure as...as...creates a comparison. The first as is followed by an Adjectiveor Adverb. The second as is followed by a Noun, a phrase, or a whole Clause.

• ·        They are AS hungry AS you.
• ·        They are AS hungry AS you are.
• ·        They are AS hungry AS they were last night.
  

Don’t uselike to introduce examples.Instead, use the phrase such as.

• ·        Wrong: I enjoy fast food LIKE hamburgers. (fast food SIMILAR TOhamburgers)
• ·        I enjoy fast food SUCH AS hamburgers.

我总结一下
like是介词，意为“像”，后面只能跟名词或代词，而且不能做列举用。

As可做连词或介词，连词后可以跟句子，连词有三种意义（其中一个是“像”），介词后不能跟句子，介词也有三种意义，做介词时的As没有“像”的意思

吴下锕蒙

何为句子？简言之就是有主谓
举OG74题的例子，although作为连词后面跟句子，depite作为介词不能跟句子，下面几句都是正确的

•        Although it covers the entire planet, Earth’s crust is neither seamless nor stationary, but rather fragmented into mobile semirigid plates.
•        Despite its covering…, despite the fact that…,

不客气啦 like与as蛮经常碰到的，一次性搞懂它就好了

as +名词， 直接把as理解成“作为”，就不会和like搞混了

例如：As a parent, I feel that more should be done to protect our children. --朗文5th

“作为一个家长，我觉得XXX”，而不是"我"和"parent"之间的对比了

In any ofthese prepositional senses, As does not mean “similar to.”
·        I will jump up LIKE a clown. (= in a clownishmanner)
·        I will jump up AS a clown. (= in a clown suit)
如果这里as不翻译成“像”，那是什么意思呢
