二、语法知识：现在完成时
(一)定义
现在完成时主要用来表示过去发生的动作对现在造成的影响或结果 如:
I have already seen the film.
She has just had a bath.
第一句说明看电影是过去发生的,用了现在完成时是要表示说话者可能不想再看了,或者对该电影的内容已经很熟悉了,等等
第二句说明她洗澡是过去发生的,用了现在完成时是要表示她不需要再洗澡了等
(二)基本结构
现在完成时的句子结构一般为:
肯定句主语+have/has+过去分词+其他成分
We have already had lunch.
He has been away for a week.
肯定句:主语+have/has+动词的过去分词+其他
否定句:主语+have/has+not+动词的过去分词+其他
一般疑问句:Have/Has+主语+动词的过去分词+其他
特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词+其他)
(三)主要用法
1 表示过去发生并且已经完成的动作对现在造成的影响或结果 此时,常和谓语动词一起使用的副词有already just never ever yet等 如:
They have already come back from the museum.
She has already finished her homework.
2 表示过去发生的动作持续到现在,并且有可能会继续持续下去 此时,常和谓语动词一起使用的标志性词语主要有for和since,而且此时的谓语动词往往是持续性动词(如stay keep wait等) 如:
I have lived here for ten years.
He has kept the clavichord since thirty years ago.
3 表示从过去某一时间到说话时这段时间中反复发生的动作 此时,常和谓语动词一起使用的主要是表频度的副词often always seldom never等,以及表次数的单词或短语(如once twice three times) 如:
You have never listened to me like this before.
She has ever been to France.
They have visited the Summer Palace many times.
(四)动词的过去分词
1 规则变化
其变化规则与动词的一般过去时基本相同,主要是在词尾加-ed或-d 具体的有:
1)直接加-ed 如:worked played
2)以不发音的e结尾的动词后加-d 如:lived danced
3)以辅音字母加y结尾的动词后改y为i,再加-ed 如:studied cried
4)以重读闭音节结尾的动词后,双写最后一个辅音字母再加-ed 如:stopped patted
2 不规则变化
如果结合动词的过去式,动词的过去分词的不规则变化中,又有一些相对的规则现象 如:
1)AAA型 如:put put put;read read read 其中,read的过去式和过去分词虽然拼写时一样的,但其发音与原形不同,ea不再读作[i ],而是[e]
2)ABB型 如:keep kept kept;sit sat sat
3)ABA型 如:run ran run;come came come
4)ABC型 如:lie lay lain;drink drank drunk
5)AAB型 如:beat beat beaten
