3. 语法
现在完成时态表示过去已经开始, 持续到现在的动作或状态, 可以和表示从过去某一时刻延续到现在(包括 “现在” 在内)的一段时间的状语for … 及since…连用
正确使用延续性动词和非延续性动词
教学重点与难点
1. 现在完成时态的用法
　　1）“已完成”用法 (Unit 6 - Unit 8)
表示动作或过程发生在说话之前某个没有明确说出的过去时间(常指最近的过去时间),现在已经完成了, 并与现在的情况有联系.
特点是既涉及过去, 又联系现在: 动作是过去发生的, 结果是现在存在的.
换句话说, 这一用法实际上表示的是因果关系, 动作的完成是原因, 现在的情况是结果 (主要是指目前的结果, 也可以指长久的乃至永久的结果, 即表示此种结果已构成某种不会消失的状况或经验)
He has turned off the radio. 他把收音机关着.
(含义是: 收音机在一个过去的时间被关了, 说话时刻仍然关着)
The man upstairs has come home. 楼上的人已经回家了.
(含义是: 楼上的人现在在家, 有事可以去找他)
They have cleaned the classroom. 他们已经把教室打扫了)
(含义是: 他们打扫过教室了, 教室现在是干净的)
I have worked in the USA. 我曾经在美国工作过.)
(含义是: 我现在不在美国工作了, 但我在那儿工作过)
2）“未完成”用法(Unit 9）
表示动作或状态从过去某时开始, 继续到现在, 可能继续下去, 也可能刚刚结束.
The Whites have lived here since 1970. 怀特一家人从1970年就住在这里.
(含义是: 怀特一家人从1970年来到这里居住, 至今还住在这里; 偶尔可根据上下文理解为刚刚搬走)
He has been ill for eight years. 他病了八年了.
(含义是: 他病了八年了, 现在还在病中; 在特殊情况下也可理解为刚刚痊愈)
2. “未完成”用法需要注意的几个问题
1）谓语动词都是 “延续性” 动词, 即可以表示延续的情况或动作的动词, 如be, have, know, live, work, study, learn, teach, speak, talk, draw, wait, wear, walk, sleep等.
Miss Gao has taught this for three years.
高小姐教这个班已三年了.
We have learned English for six years.
我们学习英语已六年了.
Uncle Wang has worked in this factory since 1989.
王叔叔自从1989年就在这家工厂工作了.
2）可以和表示一段时间的状语连用. 这段时间从过去某一时刻延续到现在(包括 “现在” 在内), 可由for或since引导的短语来表示.
for引导的介词短语表示一个时间段，指某个动作或情况到现在为止已持续了多久, 对此提问用how long.
I have waited for you for two hours.
我已经等你两个小时了.
We have known him for ten years.
我们认识他有十年了.
since作为介词可接一个时间名词, 该时间名词必须是过去的某一时间点, 表示 “自从(过去某一时间点)以来”.
The twins have studied in this school since 1996.
自从1996年以来, 这对双胞胎一直在这所学校学习.
I have stayed here since last spring.
自从去年春天以来, 我一直呆在这里.
since作为连词可引导一个时间状语从句, 从句中的动词应该是一般过去时, 指过去的某一动作点, 表示 “自从(过去某一动作点)以来”, 因此since从句中的动词一般是短暂性动词.
She has been very busy since she came back.
她回来后一直很忙.
He has lived with his aunt since his mother died.
自从他母亲去世以来, 他就跟他的姑妈住在一起.
3）还可以和下列包括 “现在” 在内的时间状语连用, 如this morning (afternoon, evening), today, this week (month, year), these days等.
We have planted many fruit trees this year.
今年我们已经栽了很多果树.
She has written two letters this morning.
今天上午她已经写了两封信.
3.非延续性动词的处理
非延续性动词或短暂性动词表示的是一瞬间就结束的动作, 不能延续, 如come, leave, go, lose, see, begin, start, arrive, become, die, close, join, reach, fall, get up等. 这类动词表示一霎时发生的动作, 即表示一时性或一次性动作, 不能与表示动作延续的时间状语for…或since…连用，即它们不能用于＂未完成＂用法中．但是，它们可以用于 “已完成”用法中, 说明某个动作的结果还存在, 如:
可以说 不可以说
He has come back. He has come back for three days.
He has died. He has died for two years.
He has left home. He has left home for two months.
He has joined the army. He has joined the army for one year.
The film has begun. The film has begun for half an hour.
既然非延续性动词不能表示持续性, 那么可以将该动作改为可持续的状态, 做如下处理:
1）He has been back for three days.
= He has been back since three days ago.
= It’s three days since he came back.
= Three days have passed since he came back.
= He came back three days ago.
他回来已三天了.
2）He has been dead for two years.
= He has been dead since two years ago.
= It’s two years since he died.
= Two years have passed since he died.
= He died two years ago.
他死了两年了.
3）He has been away from home for two months.
= He has been away from home since two months ago.
= It’s two months since he left home.
= Two months have passed since he left home.
= He left home two months ago.
他离家已有两个月了.
4）He has been a soldier for one year.
= He has been a soldier since one year ago.
= It’s one year since he joined the army.
= One year has passed since he joined the army.
= He joined the army one year ago.
他参军已有一年了.
5）The film has been on for half an hour.
= The film has been on since half an hour ago.
= It’s half an hour since the film began.
= Half an hour has passed since the film began.
= The film began half an hour ago.
电影开始已经有半个小时了.
[注] It’s … since …句型中的It指的是时间, 可以说It has been … since … , 但习惯上常说It’s … since … .
[注]某些非持续性动词用于现在完成时的时候不能接for或since引导的时间状语, 但其现在完成时的否定形式可以表示否定状态的延续, 可以与for或since引导的时间状语两用。
I haven’t seen him for a long time.
我好久没有见到他了.
I haven’t heard from him since he left.
自从他离开以来我一直没有收到他的来信.
She hasn’t left home ever since she lost her job.
自从她失业以来她未离开过家.
4. have been at/in … 和have been to …
have been at/in … 表示到目前为止的一段时间一直在某处.
have been to …表示去过某地.

IV. 阅读理解
Basketball is still a young game. It is not yet a hundred years old. In the winter of 1891, a certain college was having some trouble with its boy students. The weather was bad and the students had to stay indoors. As they could not take part in their usual outdoor sports, they were unhappy, and some even got into fights from time to time (经常).
Finally, some of the teachers at the college asked Dr Naismith to invent a game so that the students might have something to play at. It was not easy to invent such a game because it had to play indoors, and the court (院子) was not very large.
Dr Naismith thought for a few days and invented a kind of ball game. It was a fast, exciting game with much moving and passing of ball. It was played between two teams. In order to make a score (得分), the ball had to be thrown into the basket ten feet above the floor on the wall. At each end of the court there was such a basket. At first, Dr Naismith had planned to have the ball thrown into a box. As he could not find boxed of the right size, he had to use fruit baskets instead. That is how the game got its name.

play
B. Dr Naismith could hardly invent a new game
