from verb to noun and articles

[rinotg]

Dear Teacher,

I have been asked to rebuild the following sentense by changing the verb to noun :

"The market is expanding considerably"

I wrote :"There is a considerable expansion in the market"
the correct answer was :There has been a considerable expansion...

Why did he use present perfect ?

Also I don't understand if or when to put the articles (a/an/the).
for example : the sentense "There has been a collapse in consumer confidance" consumer is noun so basicly I have to put a before it but
they didn't use it , why? and do u have a tool to find out when to use article.

Waiting for your kind reply.

He used the present perfect because the original sentence used present progressive. If the original had been "The market expands considerably" then "There is a considerable expansion in the market" would match. However, the present progressive indicates an ongoing process that your new sentence should reflect. We can't say "There is being a considerable expansion in the market" because that would just sound silly. The present perfect is better because it shows that the expansion is not just a present condition; it started sometime in the past and continued to the present.

1) You do not put "a" before "consumer confidence" because the noun here is confidence, and consumer is acting as an adjective. If you want to treat consumer as a noun, you could say "a consumer's confidence" or "the consumers' confidence". Confidence (the noun) is not singular. 2) You do not put "a" before "consumer confidence" because "confidence" is not being used as a singular noun. It is not one consumer confidence, but an indeterminate amount of consumer confidence. I do not put "the" before "consumer confidence" because I am talking about something general rather than specific. I can talk about "green apples" in general or I could talk about "the green apples" in my bowl, though the latter would actually depend on having green apples in my bowl where, sadly, I have none.

Dear Nonsense,

I wish english was nonsense to me.

Thank u for your reply, by the way in Israel u will find plenty of green apples.

one more question for today : the word " being"

usually I use the word being for active sentences for P.progressive,

but I find it more in sentences like " sorry for being late"

what grammerly is the roll in this sentences?
