fewer vs less
Use fewer for things you can count individually
and less for things you can only measure
For example
There were fewer days below freezing last winter. Days can be
counted
I drink less coffee than she does. Coffee cannot be counted
individually it has to be measured
---------------------------------
How do you do
vs
How are you
If I had a Euro for every time someone got this one wrong - I'd be a
rich bunny
How do you do
This is not a question. It is another, very formal way of saying
"Hello." It is also very British
The correct response is; "Pleased to meet you." or "How do you do." or
just Hello
We only really use it the first time we meet someone
How are you
This is a question
A polite response is; I'm fine thanks. And you
---------------------------------
I vs me
Usually we choose the correct form by instinct
For example
Give that to me. not to I
But there are still times when people make mistakes with these two
pronouns. I/me is difficult when it is coupled with another pronoun or with
a noun. This is when you have to think about the subject/object in a
sentence
For example
The teacher gave the homework to my friend and me. not I
! If you don't understand why the above sentence is correct, simplify
the sentence by dealing with the two people separately
The teacher gave the homework to my friend
The teacher gave the homework to me
The teacher gave the homework to my friend and me
