Clive, with all due respect but sentence number two is not correct anymore if you change the tense.
If the question is in present perfect, it should also be answered in present perfect.
The question starts from a point in the past and refers to the present. Therefore the answer has to do the same.

Hi ABCD. You need to come back on this. The grammar in both versions is identical (continuous). Only the number of years has changed.

.
I suppose that you want your sentences PARSED. I'm not going to do all of them for you. I'll do the first one:

Where -- adverb
are -- linking verb, simple present
you -- pronoun subject

I -- pronoun subject
've been waiting -- verb, present perfect progressive
for -- preposition
2 -- cardinal number as adjective
hours-- noun object of preposition

(for 2 hours -- prepositional phrase acting as sentence adverb)

I got 4/5 and my mistake was number 4. According to T&M present perfect must be used with SINCE. You should use AGO if you want to use the simple past. Let's see what native speakers think.

until now+ present perfect

Tuongvan — Thu, 09 Oct 2008 15:30:06 GMT

Hi teachers,
My grammar book says the present perfect is used with "Until now", but why do they use the past perfect in the following sentence that I have picked up from a British newspaper

The West Country â where the Ministry of Defense has a number of high-security establishments â had until now only been considered "a low risk."

Thank you in advance

I've run into the following question

when you received a notice of the Court ruling, say, from the 9th Appellate Court, say, on September 24 (so two days from now), and you are reporting it
to your friend. Under this circumstance, which one of following sentences is correct

1. I have received a court ruling from the 9th Appellate Court on September 25th, 2008.

2. I received a court ruling from the 9th Appellate Court on September 25th, 2008.

By the way, if you had received the court ruling on September 26th or 24th, assuming today is September 27th, what would be the appropriate sentence , particualry
use of present perfect tense would be approrpaite under this circumstance ? or use of the present perfect tense would be more appropriate the more distant from today the time in which the referenced action took place ?

On a side note, I am wondering about whether I should use "referring to" or "reference to" when I have to write the following sentence " the sequence of some amino acids should be defined by referring to their respective sequence identifying numbers" or "the sequence of some amino acids should be defined by reference to their respective sequence identifying numbers." Between the two sentences, which one is more approrpaite ?

Thanks in advance

Re: present perfect or present perfect continuous ???

CalifJim — Mon, 15 Sep 2008 21:18:08 GMT

Is the action something that extends continuously, habitually, or regularly from the past to the present? That is, at any point in time between the start of the action and now, if you looked at what was happening, would this action be happening? If so, you need the continuous tense. Otherwise, don't use the continuous tense.

Look at the second example.

Marie has been in Stockholm for a few weeks now. She ..... with her friend Inga while she's there.

Was she staying with Inga 13 days ago? Yes.

Was she staying with Inga 12 days ago? Yes.

Was she staying with Inga ...

Was she staying with Inga two days ago? Yes.

Was she staying with Inga yesterday? Yes.

It seems that the action of "staying with Inga" has been "happening" continuously. So she has been staying with Inga while she's there.

______

Now take a look at Example 7.

I ... a couple of times before, but I just can't get the hang of it.

In my whole life I only played squash a couple of times, so that doesn't seem like a lot, does it?

Was I playing squash yesterday? Was I playing squash the day before? What about the day before that? What about the day before that? You would have to answer "Probably not" to each of these questions.

Obviously, I do not play squash regularly. I do not play habitually. The continuous tense does not apply. So I have played a couple of times before.

In general, you can't use the present perfect continuous when you have done something a certain number of times.

Now maybe you can try them all yourself.

Present Perfect more formal(america english)

YSchneider — Thu, 07 Aug 2008 19:43:19 GMT

I feel like in American enlish people tend to chose present perfect instead of simple past,

to be more formal! Is it true? What do you think about it? For instance:

Thank you I have received your mail! (formal)

Thanks I received your mail! (informal)

The number you have dialed is incorrect! (formal)

The number you dialed is incorrect! (less formal)

Re: Present perfect/simple past in since clause

I'm afraid, Marius, that you are never going to persuade me that "It's years since I've had a cigarette", and similar expressions, are in any way exceptional, unusual or strange. In my experience, this form of wording is routinely and quite naturally used by large numbers of native speakers at all levels of language proficiency. It's possible that there may be regional differences, of course, and we've noted that some individual speakers object to them.
