将来完成时

1. 将来完成动作的开始时间。

现在完成时是以‘现在’作为‘坐标时间’,来描述开始于现在之前的动作持续到现在。过去完成时是以‘过去’作为坐标时间,来描述与开始与过去之前(即过去的过去)的动作持续到过去。同理,将来完成时是以将来为坐标时间,来表示开始于将来之前(可能是现在、过去或将来)的动作持续到将来。注意,这里说的动作开始于‘将来之前’,意味着动作开始的时间可能是过去的某一时刻、可能是现在的某一时刻,或者也可能是将来的某一时刻。但动作开始的时间并不重要,关键是说话人要站在将来的某一时间来谈某一动作的完成情况。例如: We will have taken five exams by next Friday. 1). 我们 可能是昨天开始考试的,比如说成:

We started our exam yesterday and we will have taken five exams by next Friday. 2)可能是今天开始考试的。比如说成:

We have started our exam today and we will have taken five exams by next Friday. 3)可能是明天开始考试的。比如说成:

We will started our exam tomorrow and we will have taken five exams by next Friday. 但具体是那一天开始的并不重要,说话人强调的是她们一共有五门考试 到下个星期五之前。我们将完成五门考试。

2. 将来完成时的三种用法。

将来完成时态有三种基本用法。 1. 延续事件,(要与表示延续时间 延续动作的词连用)

表示在将来某一时刻之前开始的动作,一直延续到该时刻,并可能继续延续下去

如: I will have taught English in New Oriental School for five years by the end of next month.

I will have learned 8.000 words be the end of next year.

The old man will have worked in this factory for 50 years when he retires next

month.

2. 重复事件

表示在将来的某一时刻之前开始的动作,并在该时刻之前的一段时间内重复发生。如: By five o’clock this afternoon the spaceship will have traveled eleven times round

the world.

3. 单一事件

表示在将来某一时刻之前开始的动作,到该时刻之前已经完成。如: We will have finished our exam by the end of next week.

By the year 2050, scientists probably will have discovered a cure for cancer. I will have finished my homework by the time I go out on a date tonight.

Since的用法:

1. since + 短暂动词 : I have worked in this company since I left school. 2. since +延续动作 : It’s been three years since I worked in this company

我不在这家公司工作有三年了

It’s been three years since I have worked in this company. 我在这家公司工作有三年了。

当since 接延续动词时,用一般过去时,表示从句动作(结束)以来,主句活动在持续;若用现在完成时,则表示从句动作‘开始’以来,主句活动在持续。
