I have struggled with As/ Like and now I can nail any damn SC on the usage. So for those who are still trying to fix the problem
As Vs Like----------
"She sings like her mother" - correct
"She sings as her mother does" - correct
Susan, like her mother, is a good singer. - correct
"She sings like her mother does" - wrong
Joe, like Mary, has a cat. - correct
Joe has a cat, as does Mary. - correct
There are fundamentally 4 differences between "as" and "like".
1. As introduces clauses (which have verbs) and like introduces phrases (which don't have verbs).
2. As clause construction is used to introduce comparisons that are real. Like phrase constructions are preferred when making comparisons that are not real but imaginary. (See the above McClintock example)
3. "As" is also used as a substitute for "in the capacity of". Eg. As the president of USA, George Bush.....
4. Idiomatic differences: Used as (Correct) Used Like (Incorrect) / Regarded as (Correct), Regarded Like (Incorrect). There is just one exception (that I have come across) to the idiomatic constructions using the verb "act", where one has to infer the meaning before using "as/like". "Act as" is used when a function of an inanimate object is described. Eg. In the flood, the wall acted as a dam. However, "act" is followed by like to mean to behave or comport oneself and describes the action of a person. Eg. He acted like a fool.
Lets look at some examples -
1. More than thirty years ago Dr. Barbara Mc-Clintock, the Nobel Prize winner, reported that genes can “jump,”
as pearls moving mysteriously from one necklace to another.(A) as pearls moving mysteriously from one necklace to another
(B) like pearls moving mysteriously from one necklace to another
(C) as pearls do that move mysteriously from one necklace to others
(D) like pearls do that move mysteriously from one necklace to others
(E) as do pearls that move mysteriously from one necklace to some other one
Red flag: "as" is MOST dangerous here.

(B) As rare as something becomes, whether it is
(C) As something becomes rarer and rarer, like

twice as fast as the 1970's.
A.twice as fast as

that Halley’s comet will pass the next time it appears.

(B) that Halley’s comet is to be passing
(C) as Halley’s comet
(D) as will Halley’s comet

like nonfiction books, seems to be on the rise.

7. Proponents of artificial intelligence say they will be able to make computers that can
understand English and other human languages, recognize objects, and reason
as an
expert does—computers that will be used to diagnose equipment breakdowns,

equipment breakdowns or the decision whether or not a loan should be
authorized
(E) like an expert, to be used to diagnose equipment breakdowns, deciding

C. generated through wind power now as was the case

Another point - "will" never takes singular verb.
