non-fact, and is typically found in that-clauses following such constructions as “it’s time…”, “I wish…”, “I’d rather…”.etc, and in adverbial clauses of rejected condition, ie a condition which is not likely to be fulfilled, eg:

7.3Uses of present progressive

1) to denote an action in progress at the moment of speaking

A: what are you doing?B: I’m writing a letter.

To denote an action in progress at a period of time including the present.

Compare: He works in a chemical factory.

accompanied by an adverbial of frequency such as always, continually, constantly, or disapproval. By contrast, the simple present lacks the subjective, emotional tone of the present progressive and states a fact objectively. Compare:

p.m.?They were building a dam last winter.

To denote a past habitual action George was getting up at five every day that

week. As in the case of the present progressive, the

past progressive can also collocate with such adverbial of frequency as always, constantly, continually, forever, to express emotional feelings, especially feelings of annoyance or disapproval on the part of the speaker, eg:

My brother was always losing his keys. 11E,F&G

7.5 Uses of present perfectivetwo chief uses: “finished” use and

“unfinished” use. The finished use refers to the present

result of a past event still operative at the present moment.

The “unfinished” use of the present perfective denotes that an action or state extends over a period lasting up to the present moment, possibly extending into the future as well.

Compare:He’s turned off the light. (The light is still off now.)He’s lived here since 1960. (“The period of residence extends either to the present---the usual interpretation----or to some specified date in the past.”)

Henry has got married for six years.

Henry got married six years ago.

Henry has been married for six years.

7.6 Uses of Present perfective progressive

The use of the present perfective progressive ( have / has been + -ing participle) has much in common with the “unfinished” use of the present perfective.

Compare:I’ve been writing letters for an hour ( and I’ve still got some more to do).I’ve been sitting in the garden (and have just come indoors).

In many cases these two forms can be used interchangeably:We’ve been living here for ten years.We’ve lived here for ten years.

Means of Expressing Future Time

In its long history, English has not developed a special verb form that might be rightly labeled FUTURE TENSE corresponding to the time tense parallel for present and past. There are a number of constructions that can be used to denote futurity in English. The present lecture will deal with these future expressions.

Constructions denoting future time In English, future time is expressed by means

of modal auxiliaries, by semi-auxiliaries, or by the simple present and present progressive forms.

1 ） Will/shall+ infinitive the future meanings expressed by these

auxiliaries are very often coloured by modal meanings from prediction to intention and volition, eg:

You will feel better after taking this medicine.I ’m sure I shan’t lose my way in the woods.I promise to pay him back in time, but he won’t lend it to me

2) Be going to+ infinitive This construction is usually used to

express two meanings; intention and prediction. Compare:

He’s going to be a doctor when he grows up.He’s not going to cheat me again (= I won’t let him cheat me again).

I believe China will become one of the richest country in the world.

If you are going to attend the meeting, you’d better leave now.

3) Present progressive Its basic meaning is an action that will happen

in the near future according to a present arrangement, plan .or programme.

As a future form, the present progressive is widely used with verbs of movement from one place to another such as go, come , leave, start; arrive, etc, though also applicable to other dynamic verbs, eg:

We’re leaving on FridayWe’re moving to a different hotel the day after tomorrow.I’m spending my holidays in Switzerland this year.

Mary and Jane are going to meet tonight. Mary and Jane are meeting tonight.

4) Simple present The future use of the simple present is more

frequent in dependent, especially conditional and temporal, clauses than in main clauses, eg:

If she comes, I’ll tell her all about it.It won’t be long before the rain stops.

In main clauses, the simple present refers to an immutable future event predetermined by a timetable or a schedule which is very definite and unalterable, eg:

She retires next month.Tomorrow is Saturday.Next Christmas falls on a Thursday.

5) Will/shall + progressive/perfective infinitive

If we want to express a colourless, pure future, we can use “will/shall + progression infinitive” This construction usually implies an action which will occur in the normal course of events without any human involvement, ie without being coloured by volition or intention:

The train will be arriving at two o’clockI shall be writing to you soon.Will you be going home next weekend?

6) Be to +infinitive a future happening based on a present plan

or arrangement , eg: I am to have tea with Betty this afternoon.

There’s to be an investigation. in newspapers, and in headlines with verb

be often omitted to save space, eg: The Queen is to visit Japan next year. Another use is to convey orders, instructions,

or prohibitions; it can also connote possibility or destiny, eg:

You are to stand here. Do you understand?Tell her she’s not to be back late.The dictionary is not to be had here.

7) be about + infinitive The talk is about to begin. It’s about to rain.

I will sail for the desert land. I am going to sail for the desert land. I sail for the desert land. I am sailing for the desert land. I am to sail for the desert land. I am about to sail for the desert land. I will be sailing for the desert land. P.227, 13A
