I.Grammar Points

A tense system is a system associated with the verb where the basic contrasts in meaning have to do with the location in time of the situation,or the part of it under consideration.This clearly applies to the system illustrated in [1].The clauses are interpreted imperfectively,and the was in [1a] indicates that the state in question obtained at a time in the past,while the present tense in [1b] indicates that it obtains in the present.Past and present time are relational concepts.Usually past time is understood as time preceding the time of speaking,and present time is time simultaneous with the time of speaking.The examples in [1] illustrate the most central use of the two primary tenses,but both have a range of other uses too:the relation between tense and time in English is not at all straightforward.

[1] a.She was in Bonn.b.She is in Bonn.

1.The present tense

(a) Present time

The most basic use of the present tense is to indicate present time more specifically,time that coincides with the time of utterance,as in [2b].

But the time of utterance is of course very short.It often takes only a second or two to utter a sentence.So naturally there are severe restrictions on the use of the present tense in clauses with perfective interpretations.Compare these two examples:

[2] a.I promise to be back for lunch.b.Sue mows the lawn.

The salient interpretation of [2a] is perfective:there is a single act of promising which is performed by uttering the sentence.The act of promising and the uttering of the sentence thus occupy the same brief period of time (two or three seconds).

But [2b] cannot under any normal circumstances be interpreted in terms of a single act of mowing the lawn at the time of speaking.It takes much longer to mow a lawn than to utter a sentence,so the present time cannot be the time of the situation considered as a totality.The natural interpretation,then,is an imperfective one:we take the sentence to describe a state of affairs where Sue regularly or habitually mows the lawn.This state—like that in [1b]—holds at the time of speaking,but began before then and will (presumably) continue after it.

(b) Future time

The present tense is often used for situations located in future time.In main clauses this is restricted to cases where it can be assumed that we have present knowledge of a future event,as in:

[3] a.The next high tide is at 4 o'clock.The sun rises tomorrow at 6:10.

b.Exams start next week.We arrive home two days before Easter.

(c) Past time

In certain types of narrative,especially in informal style,the present tense is used instead of the past time events,even in discourses that have begun in the past:

[4] I was waiting at the bus-stop when this guy drives up and offers me a lift in his BMW so I say"Well,I don't know,"and he says"You can trust me,I'm a grammarian,"so I get in,and we go.

2.The past tense

(a) Past time

The central use of the past tense is to locate the situation,or the part of it under consideration,in past time.Compare the present tense examples in [3a] with their past counterparts:

[5] a.I promised to be back for lunch.b.Sue mowed the lawn.

Here [5a] again has a perfective interpretation:it reports a promise made in the past.Example [5b],however,can be interpreted either imperfectively or perfectively.In the former case it is the past time analogue of [2b],with Sue habitually or regularly mowing the lawn.This state of affairs held at the time that's being referred to.

Perfective interpretations of present tense clauses with present time reference are restricted to situations of very short duration,since they have to be co-extensive with the act of utterance.No comparable constraint applies with the past,however,and thus [5b],unlike [2b],can readily be used perfectively to denote a single act of mowing the lawn located as a whole in past time.

(b) Modal past

There is a second important use of the past where the meaning has to do not with time but with modality.We call this the modal past use.Modality is a type of meaning that is characteristically associated with mood rather than tense.At this point it's enough to say that it covers various kinds of cases where the situation described in a clause is not presented as factual.The modal past is used to present the situation as,in varying degrees,modally remote.What this means can best be understood by comparing the modal past with the present tense in such examples as those in [6],where in each pair the time is the same in [b] as in [a].

Because of the contrasting meanings of glad and wish,we understand from [(1) a] that they do in fact live nearby,and from [(1) b] that they don't.In [(1) b] they lived nearby is thus interpreted counterfactually,i.e.as contrary to fact,or false:this is the highest degree of modal remoteness.

A lesser degree of modal remoteness is seen in [(2) b]:this doesn't imply that she definitely won't arrive tomorrow,but it suggests that it may well be that she won't (perhaps I'm proposing a change to current arrangements where she's arriving at some other time).In these two examples the modal past is grammatically obligatory,for wish requires a past form of the verb in a finite complement,and so does the idiom would rather.

In [(3)-(4)],we find something different again:here there is a choice between present tense and past.These examples illustrate an important distinction between two kinds of conditional constructions,open,as in [(3) a/(4) a],vs.remote,as in [(3) b/(4) b].

The open type characteristically leaves it open as to whether the condition is or will be fulfilled:he may love her or he may not;you may leave now or you may not.

The remote type,by contrast,generally presents the fulfillment of the condition as a more remote possibility.So [(3) b] suggests a readiness to believe that he doesn't love her;this is the version I'd use,for example,in a context where he's not planning to change his job and I'm arguing from this that he doesn't love her.Similarly,[(4) b] presents your leaving now as somewhat less likely than in the case of [(4) a]:it would generally be preferred,for example,in a context where your current plans or inclinations are to leave later.

(c) Reporting

A third use of the past shows up in indirect reported speech.Notice the contrast between has and had in this pair:[7] a.Kim has blue eyes.b.I told Stacy that Kim had blue eyes.

If I say [7a] to Stacy,I can use [7b] as an indirect report to tell you what I said to Stacy.I'm repeating the content of what I said to Stacy,but not the exact wording.My utterance to Stacy contained the present tense form has,but my report of it contains past had.Nonetheless,my report is entirely accurate.This kind of change in tense is referred to as reporting.

The most obvious verbs of reporting are in the past,like told or said.It would not occur with present tense verbs of saying;in the present tense,my report would have been I tell Stacy that Kim has blue eyes.In fact,even with past reporting verbs backshift is often optional:you can keep the original present tense instead of reporting it.Instead of [7b],therefore,we can have:

[8] I told Stacy that Kim has blue eyes.

Although indirect reported speech represents the most obvious case,backshift also happens quite generally in constructions where one clause is embedded within a larger one containing a past verb:

[9] a.Stacy didn't know that Kim had blue eyes.

b.I wondered at the time whether they were genuine.

c.I wish I knew if these paintings were genuine.

All the underlined verbs have reported tense.Notice in particular that the knew of [9c] is actually a modal past,and doesn't refer to past time at all;but it still provides a context in which backshift can take place.So reporting can't be understood at all on the basis of some simple ideas about past tenses referring to past time;it's a special grammatical principle about the use of the past tense infection.

3.Verb Groups

Quite often,verbs in English occur in groups rather than singly.Each group consists of a main verb,which is always at the end of the group,preceded by one or more auxiliary verbs ("helping verbs"),as in He could have been crying.Look at the sentences below [10-20].Each of them contains a verb group:

[10] He is washing his dog.

[11] He was washing his dog at that time.

[12] He has taken his dog for a walk.

[13] He had taken his dog for a walk when I called.

[14] He can jump over this fence easily.

[15] He could jump over this fence when he was slimmer.

[16] He should have taken his job more seriously.

[17] He has been arrested many times.

[18] He had been waiting for two hours when she finally arrived.

[19] He did not say that he was unhappy.

[20] Did he say that he was unhappy?
