there is a very sligh difference between the two \nthe two mean that some thing happened in the past and still happening but the past perfect continous tense gives more emphasis on this point .however,the matter depends on the dialect whether American or British.

'has happened' is in present perfect tense while 'had happened' is in  past perfect tense. just look for the linking verb like, is, are, has, was , were, will and shall. \n\nremember,\n\npresent linking verbs: is, are,\npast linking verbs: was, were\nfuture linking verbs: will, shall\n\nit is effective when there is linking verb, but how about if none of this have, then you can use the s, ed and d that support a verb.

The first one is correct because "lately" implies a link between present and past, and that's the "present perfect" (have slept).\nThe second one is completely incorrect because the tense "present" doesn't draw this link between present and past.

No, it's just the perfect tense.\n\nPassive is switching a sentence into something like "The car had been driven by me" when you can just say "I drove the car."\n\nYou're just stating that these particular things happened in the recent past.

'get' is correct. The verb which needs to be in past tense is 'to do', not 'to get'

It depends if it is past tense or present tense.  It "drove" you crazy (happened yesterday)  or it "drives" you crazy (happening right now).  Also, for past tense, "this WAS one of those ....."

if you're talking about fell, as in to fell a tree, then the past tense is felled. If you're talking about fall, then fell is the past tense.

I don't really understand your question.  Do you mean from past tense to present or from a simple sentence to a complex one or what?  Please add details.

That is a correct present perfect progressive passive sentence construction, except you would need to keep the "on", not put it in parenthesis. However, it is a very awkward sentence. Passive voice is best avoided unless you have no choice because you don't know the agent of the verb, or because you are trying to make a point. Passive voice becomes even more convoluted in the progressive (continuous) tenses. There are other ways of expressing the same thing. \n\nThe point is, though, you did construct a proper sentence.\n \nPresent perfect = have/has + past participle of the next verb. \nProgressive/continuous = form of "be" + present (-ing) participle of the next verb. \nPassive voice = form of "be" + past participle of the next verb. \nPut that together and you get Have + past participle of be/been + present participle of be/being + past participle of cheat/cheated. (Present perfect progressive passive voice)\n\nHave been being cheated.

The tense depends on where it is at in the resume.\n\nAn objective section - so be future tense.\n\nYour current job should be present tense\n\nPast jobs should be past tense.

I can't believe all these people saying "Mark and I"  !!!  "Mark and me" is correct!\n\nSimply take "Mark" out of the sentence and see if it sounds right.\n\n"Could you please copy I on these communications?"  It doesn't work!\n\nAnd the first one is correct.  The second sentence uses the reflexive pronoun "myself," which doesn't make any sense.  Could you please copy myself on these communications?  You would not ask somebody to do it, if you were going to do it yourself.
