The use of the Present Perfect Continuous tense in this example indicates that, at thetime of speaking or writing, the bus has completed one hour of continuous waiting.b. FormationThe Present Perfect Continuous tense of any English verb is formed from the PresentPerfect of to be, followed by the present participle of the verb. For instance, thePresent Perfect Continuous tense of the verb to work is conjugated as follows:I have been workingyou have been workinghe has been workingshe has been workingit has been workingwe have been workingthey have been worki ngThus, it can be seen that the Present Perfect Continuous tense has two auxiliaries. Thefirst auxiliary is have or has, and the second auxiliary is been.See Exercise 8.c. Questions and negative statementsWhen a verb has more than one auxiliary, it is the first auxiliary which must change itsform to agree with the subject of the verb. It is also the first auxiliary which is used toform questions and negative statements.Questions are formed by placing the first auxiliary before the subject of the verb. Forexample:Affirmative StatementI have been working.You have been working.He has been worki ng.She has been working.It has been working.We have been worki ng.They have been working.Qu estionHave I been working?Have you been working?Has he been working?Has she been working?Has it been working?Have we been working?Have they been working?Negative statements are formed by placing the word not after the first auxiliary. Forexample:Affirmative StatementI have been working.You have been working.He has been worki ng.She has been working.It has been working.We have been worki ng.Negative StatementI have not been working.You have not been working.He has not been working.She has not been working.It has not been working.We have not been working.
They have been working.They have not been working.Negative questions are formed by placing the first auxiliary before the subject, and theword not after the subject. However, when contractions are used, the contracted formof not follows immediately after the first auxiliary. For example:Without ContractionsHave I not been working?Have you not been working?Has he not been worki ng?Has she not been working?Has it not been worki ng?Have we not been working?Have they not been working?With ContractionsHaven"t I been worki ng?Haven"t you been working?Hasn·t he been worki ng?Hasn·t she been working?Hasn·t it been worki ng?Haven"t we been working?Haven"t they been working?Tag questions are formed using the first auxiliary. In the following examples, thenegative tag questions are underlined. For example:Affi rmative StatementI have been working.You have been working.He has been worki ng.She has been working.It has been working.We have been worki ng.They have been working.Affirmative Statement with Tag Qu estionI have been working, haven"t I?You have been working, haven"t you?He has been working, hasn·t he?She has been working, hasn"t she?It has been working, hasn"t it?We have been working, haven"t we?They have been worki ng, haven"t they?EXERCISES for Chapter 41.
