高中英语十六种时态用法详解之如今成功启动时

1. 如今成功启动时的定义

如今成功启动时示意某举措从过去某个期间开局，不时延续到如今，并且还有或者继续下去。如：

We have been waiting for him for two hours. 咱们等他等了两个小时。

2. 如今成功启动时的结构

如今成功启动时由“have /has been + 如今分词”导致。

3. 如今成功启动时的运行

如今成功启动时所用的期间状语：this month / week / year, these days, recently / lately, in the past few + 期间段, since +期间点, for + 期间段。如：

They have been building the bridge for two month. 两个月来他们不时在修桥。

They have been planting trees this month. 这个月来他们不时在植树。

4. 如今成功启动时与如今成功时的区别

(1) 如今成功时强调举措的成功，而如今成功启动时强调举措的延续，因此，示意举措的成功，只能用如今成功时，而不能用如今成功启动时。如：

He has changed his idea. 他扭转了想法。

(2) 在示意举措的延续时，只管既可用如今成功时，也可用如今成功启动时，但如今成功启动时强调举措的启动。因此在须要明白示意举措还要继续下去时，运行如今成功启动时。如：

We have been studying here for two years. 咱们在这儿曾经学习了两年了。

(3) 有些延续性动词(如 keep, learn, live, stay, study, work等)，用于如今成功时或如今成功启动时的区别不大。如：

I have lived here for many years.=I have been living here for many years. 我在这儿住了多年了。

高中英语十六种时态用法详解之过去成功时

1. 过去成功时的定义

过去成功时既可示意过去某个期间或举措之前所出现的事件(罕用期间状语有already, before, ever, just, never, still, yet)，也可示意过去某个期间或举措之前所出现的举措不时继续到过去某个期间(常接期间状语：since +期间点, for + 期间段)。如：

When I got to the station, the train had left. 当我抵达车站时，火车曾经开走了。

We had learnt fifteen lessons by last week. 到上周为止，咱们学完了十五篇课文。

He had stayed here for two days before he left. 他走之前在这儿呆了两天。

He said that he had lived there since he was ten. 他说他十岁起就住在那儿了。

2. 过去成功时的结构

过去成功时由“had + 过去分词”导致。

3. 过去成功时的运行

(1) 与过去成功时连用的期间状语可以多种多样，经常使用它的重要依据是看其能否出当初“过去的过去”。如：

He had learnt some English before I went here. 在来这儿之前我学过一些英语。

He had written three stories by last year. 到去年他曾经写了三篇故事。

We had cleaned the room when he got there. 当他到那儿时，咱们曾经把房子弄洁净了。

He went there after he had finished his work. 他把事做完之后，就去哪儿了。

留意：当主句跟由before, after, as soon as所疏导的期间从句的举措衔接很严密时，从句也可用普经过去时。

He went there after he read the letter. 他看了那封信后就去那儿了。

(2) 过去成功时还常罕用于主句为过去时的宾语从句中。如：

He said he had been a soldier. 他说他当过兵。

They said they had seen the film. 他们说这幕电影他们看过。

(3) 在hardly / scarcely …when…, no sooner…than… 两个结构中的主句理论要用过去成功时。如：

Scarcely had he finished his supper when he went out. 他已吃完晚饭就进来了。

No sooner had he fallen asleep than he lay down on the bed. 他一躺倒床上就睡着了。

(4) 动词expect, hope, suppose, think, want等的过去成功时可用来示意未成功的方案、计划或宿愿。如：

I had hoped to see you. 我本宿愿来看你。

He had wanted to buy a house in Beijing. 他本想在北京买栋房子。

4. 过去成功时与普经过去时

(1) 过去成功时示意以过去某期间为终点以前所出现的举措或存在的形态，即：过去成功时强调“过去的过去”，而普经过去时只示意以如今期间为终点以前所出现的事件或存在的形态。如：

He studied there two years ago. 他在那儿学习了两年。(离如今两年)

He said he had studied there two years ago. 他说他在那儿学习了两年。(离他谈话时两年)

(2) 示意过去某个期间以前所延续出现的两个或两个以上的举措时，普通用and, then, but依照举措的先后顺序衔接，此时理论用普经过去时而不用过去成功时。如：

He said he went the shop and bought some food. 他说他去商店买了一些食品。
