牛津上海版九年级上册 一般过去+现在完成时讲解及练习（有答案）
展开
一般过去&现在完成时
知识点1：基本结构：
一般过去时：主语 + V-ed（动词的过去式）We went to Changfeng Park yesterday.
现在完成时：主语 + have / has + -ed分词(过去分词) We have been to Changfeng Park.
知识点2. 用法比较：
1）一般过去时：
a. 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。
b．过去时常与具体的时间状语连用，句中常含有如yesterday之类的表示过去的时间状语。
2) 现在完成时：
a. 而现在完成时通常与模糊的时间状语连用，或无时间状语。
b. 现在完成时为过去发生的，强调过去的事情对现在的影响，重点是强调现在的是影响。
知识点3．时间状语：
1）一般过去时的时间状语: yesterday, last week，…ago, in1980, in October, just now, （具体的时间状语）
2）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,
before (以前)
知识点4．动词搭配：
1）现在完成时中有瞬间动词和延续性动词的区分：
瞬间动词：come, go, leave, start, die, finish, become, get married 等后面不能跟表示一段时间的时间状语。
延续性动词：live, teach, learn, work, study, know.
[说明] “终止”、“延续”要转换：英语中的动词从词义上可以分为延续性和非延续性（瞬间动词）两种，在现在完成时态中一定要注意动词这一特性，当句中含有一段时间状语时应将这类瞬间动词转换为延续性动词。
例如： The film has begun. → The film has been on for an hour.
He has gone. → He has been away for ten minutes.
2）一般过去时中不存在瞬间动词和延续性动词的区分：
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。)
[强调] 句子中如有过去时的时间副词（如 yesterday, last, week, in 1960）时，一般不使用现在完成时，而要用过去时。
（错）Tom has written a letter to his parents last night.
（对）Tom wrote a letter to his parents last night.

【析】本句虽然没有明确的时间状语，但从语意上看出，在听的时候没有听懂这个动作发生在过去，因此应用过去时。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。
3. He said he ________ me a present unless I __________ in doing the experiment.
A. had not given; had not succeeded B. would not give; succeed

7. A: I have received his letter for a month. (T /F )
B: I haven’t received his letter for almost a month. (T/F )
答案：F T
【析】非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生地状态是可持续的。

A. Are; finishing B. Did; finish

参考答案：
1. B这种考查难度较大，往往无时间状语，需要从上下文分析、推理才行。故上两侧根据上下文分析、推理，正确答案是B。
2. C现在完成时常与already（已经），just（刚刚，正好），ever（曾经），never（从来，也不；从不），before（以前），yet（仍然）等连用。故2应选B。
3. C
4. D现在完成时常与recently（近来），so far（到目前为止），in the past/“last + 一段时间”等时间状语连用。因为上述短语表示的是从现在起往前推算的一段时间，句中的动作是从过去某一时间或时刻开始持续到现在的。故4应选D。
5. C
6. C现在完成时时常与“for +时间段或since +过去时间点”连用（含从句，从句过去时）。故6应选C。
7. C
8. B现在完成时还与once（一次），twice（两次），three times（三次），several times（几次）等表示重复次数的词语连用。故8应选B。
9. B现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday , last week , a moment ago等）连用。故9的正确答案为B。
10. B
11. A现在完成时中，非延续性动词不能与for和since引导的表示一段时间的状语连用，通常是用相应的延续性动词来代替。故11的正确答案依次为：D。
12. B
13. A
14. C
15. A。
16.A“have/has gone to + 地点”表示“某人去了某地（还未回来）”，指主语所指的人不在这儿。“have/has been in + 地点”表示“在某地呆了多长时间”，常与表示时间的状语连用。“have/has been to +地点”表示“曾经去过某地（但现在已不在那儿）。”故16的正确答案为A。
17. A
18. D
19. C
20. C
知识点1：基本结构：
一般过去时：主语 + V-ed（动词的过去式）We went to Changfeng Park yesterday.

2）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,
before (以前)
知识点4．动词搭配：
1）现在完成时中有瞬间动词和延续性动词的区分：
瞬间动词：come, go, leave, start, die, finish, become, get married 等后面不能跟表示一段时间的时间状语。
延续性动词：live, teach, learn, work, study, know.
[说明] “终止”、“延续”要转换：英语中的动词从词义上可以分为延续性和非延续性（瞬间动词）两种，在现在完成时态中一定要注意动词这一特性，当句中含有一段时间状语时应将这类瞬间动词转换为延续性动词。
例如： The film has begun. → The film has been on for an hour.
He has gone. → He has been away for ten minutes.
2）一般过去时中不存在瞬间动词和延续性动词的区分：

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)

参考答案：
1. B这种考查难度较大，往往无时间状语，需要从上下文分析、推理才行。故上两侧根据上下文分析、推理，正确答案是B。
2. C现在完成时常与already（已经），just（刚刚，正好），ever（曾经），never（从来，也不；从不），before（以前），yet（仍然）等连用。故2应选B。
3. C
4. D现在完成时常与recently（近来），so far（到目前为止），in the past/“last + 一段时间”等时间状语连用。因为上述短语表示的是从现在起往前推算的一段时间，句中的动作是从过去某一时间或时刻开始持续到现在的。故4应选D。
5. C
6. C现在完成时时常与“for +时间段或since +过去时间点”连用（含从句，从句过去时）。故6应选C。
7. C
8. B现在完成时还与once（一次），twice（两次），three times（三次），several times（几次）等表示重复次数的词语连用。故8应选B。
9. B现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday , last week , a moment ago等）连用。故9的正确答案为B。
10. B
11. A现在完成时中，非延续性动词不能与for和since引导的表示一段时间的状语连用，通常是用相应的延续性动词来代替。故11的正确答案依次为：D。
12. B
13. A
14. C
15. A。
16.A“have/has gone to + 地点”表示“某人去了某地（还未回来）”，指主语所指的人不在这儿。“have/has been in + 地点”表示“在某地呆了多长时间”，常与表示时间的状语连用。“have/has been to +地点”表示“曾经去过某地（但现在已不在那儿）。”故16的正确答案为A。
17. A
18. D
19. C
20. C
