I'm perplexed by the difference between like and as ?

the word like is a preposition, not a conjunction. It can, therefore, be used to introduce a prepositional phrase ("My brother is tall like my father"), but it should not be used to introduce a clause ("My brother can't play the piano like as he did before the accident" or "It looks like as if basketball is quickly overtaking baseball as America's national sport."). To introduce a clause, it's a good idea to use as, as though, or as if, instead.

Like As I told you earlier, the lecture has been postponed.
It looks like as if it's going to snow this afternoon.
Johnson kept looking out the window like as though he had someone waiting for him.
In formal, academic text, it's a good idea to reserve the use of like for situations in which similarities are being pointed out:

This community college is like a two-year liberal arts college.
However, when you are listing things that have similarities, such as is probably more suitable:

The college has several highly regarded neighbors, like such as the Mark Twain House, St. Francis Hospital, the Connecticut Historical Society, and the UConn Law School.



2. Taller than I / me ??

When making a comparison with "than" do we end with a subject form or object form, "taller than I/she" or "taller than me/her." The correct response is "taller than I/she." We are looking for the subject form: "He is taller than I am/she is tall." (Except we leave out the verb in the second clause, "am" or "is.") Some good writers, however, will argue that the word "than" should be allowed to function as a preposition. If we can say "He is tall like me/her," then (if "than" could be prepositional like like) we should be able to say, "He is taller than me/her." It's an interesting argument, but — for now, anyway — in formal, academic prose, use the subject form in such comparisons.
We also want to be careful in a sentence such as "I like him better than she/her." The "she" would mean that you like this person better than she likes him; the "her" would mean that you like this male person better than you like that female person. (To avoid ambiguity and the slippery use of than, we could write "I like him better than she does" or "I like him better than I like her.")




3. More than / over ??

we usually use "more than" in countable numerical expressions meaning "in excess of" or "over." In England, there is no such distinction. For instance, in the U.S., some editors would insist on "more than 40,000 traffic deaths in one year," whereas in the UK, "over 40,000 traffic deaths" would be acceptable. Even in the U.S., however, you will commonly hear "over" in numerical expressions of age, time, or height: "His sister is over forty; she's over six feet tall. We've been waiting well over two hours for her."





4. I need help with who and whom!

One of the most frequently asked questions about grammar is about choosing between the various forms of the pronoun who: who, whose, whom, whoever, whomever. The number (singular or plural) of the pronoun (and its accompanying verbs) is determined by what the pronoun refers to; it can refer to a singular person or a group of people:

The person who hit my car should have to pay to fix the damages.
The people who have been standing in line the longest should get in first.
