My NeighbourhoodTo review the use of present perfect
tense
1. Present perfect tense used for recent events
2. Present perfect tense used for experiences现在完成时
(Present perfect tense)观察下面各组句子中现在完成时的用法, 并加以总结。
1. a. I have lost my pen.
b. Someone has broken the window.
c. I haven't visited?London?before.
d. Ellen hasn't finished her homework.
e. Have you seen the sea?现在完成时的基本结构:
肯定句:
主语 + have / has + 过去分词 + 其他
否定句:
主语+haven’t /hasn’t+过去分词+其他
一般疑问句:
Have/Has + 主语 + 过去分词 + …?
肯定答语:Yes, 主格代词 + have/has.
否定答语:No, 主格代词 + haven’t/hasn’t.【归纳】2. a. Put your wallet away. I have already paid for everything.
b. I haven't spoken to her yet.
c. This is a lonely road. We haven't met another car so far.
d. We have kept our meetings secret up to now.
e. I have lived at home till now.【归纳】
现在完成时可以表示过去发生或已经完成的某一动作对现在造成的影响或结果, 常与already, yet, so far, up to now, till now等连用。这类词还有just, recently, ever, never, before等。3. a. The building has been here since 1876.
b. The man has been in prison for five years.
c. They have lived in that city all their lives.
d. Henry has been ill in recent years.
e. She has been away from her family in the last / past three years.【归纳】
现在完成时还可以表示从过去已经开始, 一直持续到现在的动作或状态, 常与since / for引导的词语, ?all one's life, in recent years,?“in the last / past +时间段”等连用。注意:
此用法中的动词常是延续性的。短暂性动词的现在完成时的肯定式不能和表示一段时间的状语连用, 需要用相应的延续性动词替换,
常见的有:leave?→?be away; borrow?→?keep; buy?→?have; begin / start?→?be on; die?→?be dead; move to?→?live in; finish / end?→?be over; join?→?be in / be a member of; fall ill / asleep?→?be ill / asleep; catch a cold?→?have a cold; marry?→?be married; come / arrive →?be。4. a. This / It is the first time that I have been to this beautiful mountain village.
b. This / It is the last time that he has gone back to his hometown.
c. This / It is the most gorgeous architecture that I have ever seen.
d. This / It is one of the most interesting books I have read.【归纳】
以下结构中that从句常用现在完成时:
1. This / It is the first / second / ... / last time + that从句
2. This / It is (one of ) +形容词最高级+ n. + that从句现在完成时与一般过去时的区别1. I lived in?Taiyuan?for 3 years.
2. I have lived in?Taiyuan?for 3 years.
这两个句子时间状语都是for 3 years, 但使用的时态不同, 表示的意义也不同。句1用一般过去时表示live这个动作在过去延续了三年, 和现在没有关系;句2用现在完成时表示live这个动作从过去开始延续至今, 甚至还可能持续下去。1. 复习现在完成时的用法。
2. 一般过去式和现在完成时用法比较。
(通过比较可以看出现在完成时强调这
一动作与现在的关系,如对现在产生
的结果、影响等;而一般过去时只表
示过去的事实,不表示和现在的关系。)They __________ many high-rise buildings in the city.
