是全部语法

一般将来时也译为单纯将来时。

例A:I shall not come if it rains tomorrow.

(如明天下雨我就不来。)

例B:My brother will leave for the United States next week.

(我的哥哥下星期要到美国去。)

解说 从句式我们可以了解一般将来时的表达须借助于助动词“shall/will”。关于“shall/will”的用法,传统文法谈得很多,同时各文法学家的理论也不很一致。更重要的是英国人和美国人对“shall/will”的用法规则并不很一致,也不很严谨,所以本书拟只提供下面的五个规则,相信各位只要把下面这五个规则学通了,你的“shall/will”的用法就可以中规中矩了。

①说或写都尽量使用“I'll, You'll, He'll , She'll , It'll, We'll , They'll …”的简缩形(如用法例2、3)。

②要表达主语的“意志”,通常都用“will”(文法上称为意志将来。)

例A:I won't see him again.

(我不愿意再和他见面。)

例B:Who will go and help that poor old man?

(谁愿意去帮助那个可怜的老人?)

Mary will . (玛莉愿意。)

③说话者要把自己的“意志”表达或行使出去,通常用“shall”。

例A:You shall not do that again.

(你不可以再做那样的事。)

例B:He shall return that book tomorrow.

(明天他必须把那本书归还。)

④第一人称问句使用“shall”。

例A:Shall I call you a taxi ?

(需要我替你叫一辆出租车吗?)

例B:Shall we tell her the truth ?

(我们可以把实情告诉她吗?)

⑤问句是“Shall…?”,答句就用“shall ~”;问句用“Will …?”,答句就用“will ~ ”。

例A:Shall you go to school tomorrow ?

(你明天须要上学去吗?)

Yes, I shall . We'll have an exam .

(是的,我必须去。我们明天有考试。)

例B:Will you go to school with me tomorrow?

(明天你要不要和我一道去学校?)

No, I won't . I'm going on a picnic.

(我不要。我已定好要去郊游。)

注:Let's …”的附加疑问通常使用“…, shall we ?”。

Let's have a rest, shall we?

(我们休息一下,怎样?)

一般将来时除了使用“shall/will + V…”以外,也可以使用下列的几种句式来表达。

1.be going to + V … (即将会……;打算将……)

例A:It is going to rain. Take an umbrella with you.

(带一把伞去。看样子就要下雨了。)

例B:The Browns are going to move to Australia.

(布朗先生全家打算迁移到澳大利亚去。)

2.be about to + V (即将……,指紧接着要发生的动作。)

例:Let's wait a minute. He is about to arrive.

(我们等一下。他即将会到达。)

3.be + V-ing …(定于……,指接近的将来动作。)

例:He is leaving for Hong Kong tomorrow morning.

(他定于明天早晨到香港去。)

4.be + to V (定于……,指预定的将来动作。)

例:She is to be here at 9:00 a.m. tomorrow.

(她定于明晨九时到达这里。)

5.V-(e)s (定于……,指接近的将来动作,但不如第3项主观。)

例:He leaves for Hong Kong tomorrow morning.

(他定于明天早晨到香港去。——与(3)项的区别在于(3)项的动作是出自主语的决定,(5)项则不一定是出自主语的决定。)

常用于修饰一般将来时的时间副词有:tomorrow, tomorrow morning (afternoon, evening), next + 时间 (next night, next Monday …, next week, month…, next summer…, next year), in (the) future (将来),soon (不久之后),in +时间 (in five days——再过五天,in two weeks——再过二星期),etc.

1.一般将来时的基本概念

2.一般将来时的形式

●will 常简略为 'll,并与主语连写在一起,如:I'll,he'll,it'll,we'll,you'll,they'll。

●一般疑问句如用will you…?其简略答语须是Yes,I will或 No,I will not;如用 Shall you…?(较少见)其简略答语须是 Yes,I shall.或 No, I shall not.。

3.一般将来时的用法

Be going to

一般将来时
一般将来时由助动词shall或will加动词原型构成,shall用于第一人称,will用于第二、三人称。这个时态的肯定、否定及疑问机构可表示如下:
i shall go.
i shall not go.
shall i go?
除英国以外的说英语的国家,在陈述句中,即使在第一人称一般也用will,在英国也有这种趋势,在口语中常紧缩为i’ll.
一般将来时表示将要发生的动作和情况:
i will (shall) arrive tomorrow.
will you be busy tonight?
the agreement will come into force next spring.
we won’t (shan’t) be free tonight.
有时表示将来的时间状语,有时没有时间状语,这时要从意思上判断是否指未来的动作或情况:
i will think it over.
who will take the chair?
will she come?
they won’t object it.
在以i 或 we 作主语的问句中,一般用shall,这时或是征求对方的意见(a),或是询问一个情况(b):
a. shall i make a fair copy of it?
which book shall i read first?
where shall we meet?
b. shall we have any classes tomorrow?
when shall we have the rehearsal?
shall i be able to find them there?
在这类问句中,近年来也有不少人用will,特别是美国。
what will we do?
how will get there?
which will i take?
注意在时间或条件状语从句中,一般不能用将来时态,而用现在时态代替:
i’ll let you have the book when i’m through.
they’ll fight till they win complete victory.
i’ll be round to see you if i have time tomorrow.
注:在两种情况下条件从句可以用一般将来时:
1. 表示愿望:
if they won’t cooperate, our plan will fall flat.
2.主句的谓语表时现在的情况:
if he won’t arrive this morning, why should we wait here。
表示将要发生的动作或情况,除了一般将来时外,还有一些其他结构和时态:
1. be going +不定式(表打算、准备作的事或即将发生或肯定要发生的事):
we ‘re going to put up a building here.
how are you going to spend your holiday?
who is going to speak first?
2. be +不定式(表示按计划安排要发生的事或用来征求对方的意见):
when is the factory to go into production?
the line is (going) to be opened to traffic next week.
am i to (=shall i ) go on with the work?
3.一般现在时(限于某些动词,表示按计划或时刻要发生的事):
school finishes on january 18th.
we get off at the next stop.
when does the winter vacation begin?
4.现在进行时(限于某些动词,表示按计划安排要发生的事):
we are having an english evening tonight.
they are playing some folk music next.
i am talking the children to the zoo (on sunday ).
在单纯表示将来情况,特别是谈一连串的事情或在带时间或条件状语从句的句子中,谓语多用将来时:
next term i will try to do better. i’ll speak more english and do more reading-aloud.
he’ll come to see you when he has time.
he’ll tell you if you ask him.
在表示打算或准备时,如不提时间、条件等,多用be going to这个结构,用一般将来时时很少的,特别是在口语中:
he is going to buy a dictionary.(很少说he will buy a dictionary.)
在谈即将发生的情况时,用be going to 这个结构也多一些。在表示按计划安排要做得事时,用be to 的时候也不少。另外还有将来进行时等时态也可表示将来的动作。
注:be about to 可表示即将作某事
we are about to leave.
he is about to retire.
一般将来时有时还可用来表示一种倾向或习惯性动作:
a drowning man will catch at a straw.
crops will die without water.
oil will float on water.
注:这一时态有时用来表示揣测(a)或容量(b):
a. that man in the middle will be the visiting minister.
b. the hall will seat 500people.
