Key structure 关键句型

I bought this car last year.去年我买了这辆车。

He came to see me this morning.今天上午他来看我。

I saw him ten minutes ago.我10分钟以前见到了他。

What has happened?现在完成时

在第4课里出现了现在完成时,现在完成时用来表示发生在过去但对现在仍有影响的一个动作。在现在完成时的句子中常有一些表示时间的词和短语。注意以下句子中的斜体字-时间状语。

I’ve already seen that film.那个电影我已经看过了。

具体讲解:

1)过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是result (结果)。

2)过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。一般过去时的时间状语:

yesterday, last week,…ago, in1980, just now, 具体的时间状语

共同的时间状语:

this morning, tonight, this April, now, once,before, already, recently,lately

现在完成时的时间状语

for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always,

不确定的时间状语

3)现在完成时可表示持续到现在的动作或状态,动词一般是延续性,如live, teach, learn, work, study, know.

过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。

举例:

I saw this film yesterday.

(强调看的动作发生过了。)

I have seen this film.

(强调对现在的影响,电影的内容已经知道了。)

Why did you get up so early?

(强调起床的动作已发生过了。)

Who hasn’t handed in his paper?

(强调有卷子,可能为不公平竞争。)

She has returned from Paris.

她已从巴黎回来了。

She returned yesterday.

她是昨天回来了。

He has been in the League for three years.

(在团内的状态可延续)

He has been a League member for three years.

(是团员的状态可持续)

He joined the League three years ago.

( 三年前入团,joined为短暂行为。)

I have finished my homework now.

—Will somebody go and get Dr. White?

—He’s already been sent for.

句子中如有过去时的时间副词(如 yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。

(错)Tom has written a letter to his parents last night.

(对)Tom wrote a letter to his parents last night.

用于现在完成时的句型

1)It is the first / second time…. that…结构中的从句部分,用现在完成时。

It is the first time that I have visited the city.

It was the third time that the boy had been late.

2)This is the… that…结构,that从句要用现在完成时.

This is the best film that I’ve (ever) seen.

这是我看过的最好的电影。
