小學(xué)五年級(jí)英語語法

  小學(xué)五年級(jí)英語語法:過去完成時(shí)

  用法:在過去的時(shí)間里,兩個(gè)動(dòng)作中,發(fā)生在前的那個(gè)動(dòng)作要用過去完成時(shí)。 結(jié)構(gòu):had+過去分詞

  After she had finished her homework, she went shopping.

  They had sold the car before I asked the price.

  The train had left before I arrived at the station.

  They had sold the car before I asked the price.

  The train had left before I arrived at the station.

  After/before引導(dǎo)的時(shí)間狀語從句放在句首要在句子后面加逗號(hào),如果放在主句后則不用加。

  1.變疑問句將助動(dòng)詞移到句首

  Had she finished her homework?

  2. 變否定句在助動(dòng)詞后面加not

  She hadn’t finished her homework.

  3. 肯定回答及否定回答

  Yes, she had. No, she hadn’t.

  4.特殊疑問句:

  What had she done?

  2

  小學(xué)五年級(jí)英語語法:現(xiàn)在完成時(shí)

  構(gòu)成:主語+助動(dòng)詞have, has+過去分詞

  用法:

  2) 表示過去發(fā)生的和現(xiàn)在有某種聯(lián)系的動(dòng)作,常和just, usually, already, since等時(shí)間副詞連用

  I have just had lunch. (飽了,不用再吃了)

  He has had a cup of tea.(不渴了,不用再喝)

  They have already had their holiday. (不能再度假了)

  The boy has already read the book. (已經(jīng)知道書的內(nèi)容了,不用再看了)

  3) 詢問別人是否做過某事一般用現(xiàn)在完成時(shí):

  Have you finished your homework?

  Have you been to Beijing?

  Have he seen the film?

  4) 表示開始于過去并持續(xù)到現(xiàn)在的`動(dòng)作

  I have lived in Beijing for twenty years.

  I have worked for this school for 1 year.

  5) 表示一種經(jīng)歷,經(jīng)驗(yàn):去過…地方,做過…事情,經(jīng)歷過…事情

  I have never had a bath.

  I have never seen a film.

  I have never been to cinema.

  I have ever been to Paris.

  Have been to表示去過,have gone to 表示去了

  I have been to London.(人已經(jīng)回來)

  He has gone to London.(人還在那里)

  6) 表示一種結(jié)果, 一般不和時(shí)間副詞聯(lián)用

  I have lost my pen.

  I have hurt myself.

  He has become a teacher.

  She has broken my heart.

  句型變化:

  ★變疑問句將助動(dòng)詞移到句首,變否定句在助動(dòng)詞后面加not.

  e.g. Have you lost your pen? I have not lost my pen.

  ★肯定回答及否定回答

  Yes, I have. No, I have not.

  ★特殊疑問句:

  What have you done?

  What has he done?

  一般過去時(shí)與現(xiàn)在完成時(shí)的區(qū)別:

  凡是有明確的表示過去的時(shí)間狀語的句子為過去時(shí)

  注意:有些動(dòng)詞表示的動(dòng)作有一個(gè)終點(diǎn),不能再延續(xù),因此不能和表示一段時(shí)間狀語連用

  錯(cuò):I’ve left Beijing for 3 days.

  對(duì):I left Beijing 3 days ago. I have been away from being for 3 days.
