2.1考点运用与知识再现——基本概念

1、现在完成时的构成：
have / has + vt. 过去分词(PP)

2、句式及变换

3、现在完成时的两种主要用法

1.过去发生的动作对现在造成的影响或结果。

I have already had my breakfast. (现在我不饿)

2.过去已经开始，持续到现在的动作或状态

I have lived here since 2009/three years ago

2.2考点运用与知识再现——时间状语

He has _______ been to Shanghai , has he ?
　　Ａ. already Ｂ.never Ｃ.ever Ｄ. Still
2、The famous writer _____ one new book in the past two years.
　　Ａ. is writing Ｂ.was writing Ｃ.wrote Ｄ.has written
现在完成时的时间状语分为四类
1、与already , just (刚好,正好）， ever , never , before ,yet 连用。
2、与recently , so far ,in the past /last few years ，today 等时间状语连用。
3、与带for和since 的时间状语连用。
4、与 once ,twice , three times ,several times 等表重复次数的词语连用。

2.3 考点运用与知识再现——与一般过去时的区别
1、-These farmers have been to the United States .
　 -Really ? When _____ there ?
　Ａ. will they go      Ｂ. did they go
　Ｃ. do they go      Ｄ. have they gone
2、-______ you ___ your homework yet ?
　 -Yes . I _____ it a moment ago .
　Ａ. Did ; do ; finished        Ｂ. Have ; done ; finished
　Ｃ. Have ; done ; have finished   Ｄ. will ; do ; finish
用法小结：现在完成时强调的是现在的情况, 它不能和表示过去时间状语连用；而一般过去时只单纯表示过去的动作或状态，和现在不发生关系，可以和表示过去的时间状语连用。

2.4考点运用与知识再现——考查非延续性动词的用法。
1、 His father ______ the Party since 1978 .
　　A. joined    B. has joined C. was in      D. has been in
2、-How long have you ____ the library book ?
　 -For about two weeks .
　　A. borrow     B. borrowed     C. are borrowing   D. kept
用法小结：非延续性动词又叫瞬间性动词或终止性动词，它们可用于完成时态，但不能与for、   since 等表示一段时间的状语连用,也不能和how long 问句连用，如果要和一段时间状语连用，应将它们转化成相应延续性动词。

2.5考点运用与知识再现——考查词组have/has been to , have/has gone to与have/has been in/at的区别。
1. Miss Green isn't in the office . she_______ to the library .
　　Ａ.has gone Ｂ. went   Ｃ.will go   Ｄ. has been
2.My parents ______ Shandong for ten years .
　　Ａ. have been to                      Ｂ. have been in
　　Ｃ. have gone to                     Ｄ. have been
用法小结
1. have /has been to… 表示曾经去过某地，但现在人不在那儿。
常与once 、twice、ever、never 等时间状语连用。
2. have / has gone to … 表示已经去了某地，现在人可能在去的途中或已在那儿了。
3. have/has been in …表示“呆在某地多长时间了，句末有一段时间.如果是小地方用at代替in
