五、一般将来时

[例句] I don’t know what will happen in the future.

2. 常用来表示将来时的结构包括:

(1) shall / will + 动词原形:(单纯) 表将来, 一般不用于条件句。

(2) be going to + 动词原形:(计划)打算做……。

(3) be about to + 动词原形:即将或正要去做某事,通常不与时间状语连用,但可与when引导的从句连用。

(4) be to + 动词原形:预定要做……。

(5) be doing 表示按计划、安排即将发生的动作,常与go, start, set out, leave, reach, arrive, return, come, move等表位移的动词连用。

[例句] I had hoped to see more of Beijing.

◆动词时态应注意的几点

1. 瞬间性动词的一般现在时和现在进行时常用来表示将来的动作。例句:

①The film begins in a minute.

②My uncle is leaving tomorrow morning.

2. 在时间、条件、让步状语从句中,常用一般现在时代替一般将来时。例句:

①Every time I listen to that song, I’ll think of my old friend.

②If you do that, I shall be very pleased.

③They’ll stand by you even if you don’t succeed.

3. 一般过去时和现在完成时的区别:一般过去时和现在完成时都表示过去所发生的动作,但现在完成时强调这一动作与现在的关系,如对现在产生的影响、结果等,所以它不能和表示过去的时间状语连用;一般过去时只表示过去的事实,不表示和现在的关系,因而它可以和表示过去的时间状语连用。如:

—Have you finished your work?

—Yes, I have.

—When did you finish it?

—I finished it last summer.

◆直接引语与间接引语转换时应注意的几个问题:

1. 人称的变化

2. 时态的变化

3. 时间状语的变化

4. 地点状语的变化

例句:

①Xiao Yi said, “I want to go to the park this afternoon.”

→Xiao Yi said (that) he wanted to go to the park that afternoon.

②Bob said, “We’ll have a meeting here tomorrow morning.”

→Bob said (that) they would have a meeting there the next morning.

◆定语从句中关系代词只能用that和不能用that的几种情况:

只能用that的情况

1. 先行词是不定代词。

例句:Please tell me everything that happened to you.

2. 先行词被形容词最高级、序数词或only, last, same, very等修饰。

例句: ①This is the most interesting movie that I have ever seen.

②This is the only book that I read during the summer holiday.

3. 先行词既包括人又包括物。例句:She talked about the writer and his works that interested her.

不能用that的情况

1. 非限制性定语从句中。

例句:He said he could speak three foreign languages, which is not true.

2. 先行词本身是that。

例句:I have that which you gave me.

3. “介词+ 关系代词”结构。

例句:The person to whom I talked just now is Tom.

◆现在完成进行时与现在完成时进行的比较:

1. 强调动作还未结束时, 多用现在完成进行时;强调动作的结果时, 多用现在完成时。例句:

①I have been painting the paining. (强调“一直在画”这个动作)

②I have painted the painting. (强调“画完了”这个结果)

2. 有些动词不能用在现在完成进行时中,但可用在现在完成时中。如:have, love, see等。例句:

①She has had a cold for a week.

②They have loved each other for three years.

③I have seen this movie.

-ing形式:

1. having done

having done是非谓语动词中-ing形式的完成式,而doing则是其一般式,它们都与句中主语构成逻辑上的主谓关系,只是doing与句中谓语动词同时发生或基本上同时发生;having done则表示动作或状态发生在句中谓语动词之前。

[例句]

①Hearing the news, they got excited. (hear 和get excited这两个动作几乎同时发生)

②Having arrived at the top of mountain, they took a rest. (arrive 发生在take a rest之前)

2. 动词后接动词的-ing形式和不定式有些动词后既可接动词的-ing形式也可接to do形式作宾语,但意义有所不同。

[例如]

① forget / remember / regret doing sth. 表示动作已经发生;

forget / remember / regret to do sth. 则表示该动作未发生。

② mean to do sth. 表示“打算做某事”;

mean doing sth. 表示“意味着做某事”。

③ try to do sth. 表示“设法尽力做某事”;

try doing sth. 表示“试着做某事”。

④ stop to do sth. 表示“停下来接着做另一件事”;

stop doing sth. 表示“停止做某事”。

⑤ go on to do sth. 表示“(做完某事)接着做另一件事”;

go on doing sth. 表示“继续做同一件事”(= go on with sth.)。

⑥ can’t help to do sth. 表示“不能帮助做某事”;

can’t help doing sth. 表示“情不自禁地做某事”。

3. have/has been doing

have / has been doing是现在完成进行时的构成,强调动作的延续过程,动作可能还在进行。而have / has done是现在完成时的构成,强调动作的结果,该动作通常已经结束。

[例句]

①I have written a book. (动作结束)

②I have been writing a book. (可能未写完,侧重最近一直忙于写书)
