As a transitive verb, “complete” means to bring to an end or a perfected status. Therefore, Action Item A is complete (adjective), or Action Item A was completed (past tense verb). Action Item A “is completed” is wrong, although “is being completed” or “is going to be completed” are proper verb forms.

Complexing is a process in which a complex is formed. Chelation is the complexing of metallic cations, such as copper, with certain organic compounds, such as EDTA. Complexing of molecules is usually accompanied by partial overlap and sharing of the electron shells of the partners.

Complete is a state of being; there is nothing that can be added or changed. Whereas completed is an act of completion – the task that was set has now been fulfilled. For example “The Bible is complete and has been completed”.

“Have you completed your work” is in present perfect tense and is used if you want to ask someone if they have completed the work just recently. Whereas, “Did you complete your work” is simple past tense, it is used if you want to ask if the work is already done sometime earlier in past.

Did you finish? is just past. You’re asking about an activity that happened before but not necessarily has relevance to the present. Have you finished? is just asking for the state of the action that has just completed or you at least it expect it to be soon.

In ‘I have finished’ the verb is the present perfect tense of the verb ‘to finish,’ and it means that I very recently completed some task. In ‘I am finished’ the only active verb is ‘am,’ and ‘finished’ is a past participle acting as an adjective.

“Have you” is used with the perfect tense. “Have you eaten yet?” “Have you got a pen I can borrow?” “Do you have” is used when “have” isn’t part of the perfect tense. “Do you have any food?” “Do you have to go to the bathroom?” After “Have you . . ” , you probably need another word : ‘ Have you got a pen ?

Both are written correctly but context/meaning-wise is different. These are interchangeable. The only difference is subtle and frequently ignored. In common usage: “Have you already done it?” tends to be used if you expect a yes answer.

ALREADY / YET in questions We can use both in questions, but the meaning is a bit different. YET simply asks if something has happened or we still have to wait. ALREADY knows that something has happened, it simply expresses surprise because it happened sooner than expected.

We usually put already in the normal mid position for adverbs (between the subject and the main verb, or after the modal verb or first auxiliary verb, or after be as a main verb): We already knew that he was coming to visit. His family had already heard the news. Joe’s already here, so we can begin..

You use “had already” if you are speaking about a past event that is referenced in the past tense. you use “Have already” when you are speaking about a past event referenced in the present tense. It depends on the sentence. ‘Have’ is perfect past (past of the present), ‘had’ is pluperfect past (past of the past).

Both are correct. However, more correctly, the present perfect continuous tense ends in a participle: “He has been practicing already for three hours.” Alternatively, we can say, “He has already been practicing for three hours.” The last usage is the most natural in English.

2 Answers. We had already been given is the correct form. The other one doesn’t sound natural. In general, in the passive voice, “already” is placed between “been” and past participle of varb.

They can all be correct. It just depends on the rest of the sentence. I have already done the laundry, but I haven’t folded and put it away yet. I already did my homework, so now I’m going out.

1. adverb [ADVERB before verb] You use already to show that something has happened, or that something had happened before the moment you are referring to. Speakers of British English use already with a verb in a perfect tense, putting it after ‘have’, ‘has’, or ‘had’, or at the end of a clause.

The adverb already means before now or before a particular time in the past. So it is usually used in the present perfect and the past perfect. However, we can also use it in the past simple in American English. Already shared your video in my facebook is OK and acceptable in American English, not in British English.

We use ‘Was completed’ when we talk about an incident which happened a time long ago or referring some incidents without exactly mentioning the time of its occurrence… On other hand, we use ‘had been completed’ to explain something which happened a few times ago or in one term recently…

Usage of “Have Been & Has Been” When we are talking about the present: If the subject of a sentence is I – You – We – They or a plural noun (cars, birds, children) we use ‘have been’. If the subject of the sentence is He – She – It or a singular noun (car, bird, child) we use ‘has been’.

“BE” is the base form of the verb “be”; “been” is the past participle of the verb “be” and “being” is the present participle of the verb “be”. “Be” is used whenever the base form of a verb needs to be used, for example after an auxiliary verb, e.g. in “You should be a good example to your younger siblings.”
