comparative degree

[Clark]

Which is better:

He is three years older than me.
He is three years as old as me.

[hanky]

Which is better:

He is three years older than me.
He is three years as old as me.

Not a teacher,
The first one is OK but I don't think the later one is correct or have the same meaning with the first one.

[Roselin]

Which is better:

He is three years older than me.
He is three years as old as me.

If you are comparing your age with the second person and there is a difference of 3 yrs between yours and his age then you will say HE IS THREE YEARS OLDER THAN ME.

He is three years as old as me is an absurd sentence. It doesn't make any sense. If I break your this sentence ' he is three years as old as me' in two sentences , we will say HE IS AS OLD AS ME,, meaning we two are of the same age. I am 23 and so he. Similarly , he is three means he is three years old.

So keeping these two sentences together , one from HE IS AS OLD AS ME and HE IS THREE and making it one , doesnt make any sense.

He is three as old as me., here you are not comparing your age with the other person.


I am not a teacher but hopefully have tried to make you understand the meaning of the above mentioned two sentences.

Thank you, Roselin. I don't know how it occurred to me to ask such a stupid question. Must be overworked.

It's ok! No problem! :- )

[norwolf]

He is three years older than me.

That sentence means:If I am 10, he is not 40 but 30.
right?
Thank you teachers.

[Clark]

That sentence means:If I am 10, he is not 40 but 30.
right?
Thank you teachers.

No, it means if you are 10 he is 13.

[norwolf]

No, it means if you are 10 he is 13.

Thank you so much, Clark
You mean 10+3=13
Here goes another one:
My age is two times older than his.
Does it mean "10*(1+2)=30" or "10*2=20"?

[Clark]

Thank you so much, Clark
You mean 10+3=13
Here goes another one:
My age is two times older than his.
Does it mean "10*(1+2)=30" or "10*2=20"?

I think the correct phrase would be :

I'm twice as old as him.

[norwolf]

I think the correct phrase would be :

I'm twice as old as him.

So I'm getting pretty confused:
Somebody says there is a sentence taken from cambridge dictionary,which is:Oxygen is 16 times heavier than hydrogen.
