英语八年级上冀教版unit 2 lesson 16课文讲解和练习

1、Unit 2 My Favourite School Subject lesson 16 unit review语法专项讲解语法专讲现在完成时： 1.现在完成时的基本概念和用法： 现在完成时由have（has）动词的过去分词构成。规则动词的过去分词的构成与动词过去式相同，不规则动词的过去分词各不相同，需个别记忆。 （1）现在完成时表示过去所发生的动作对现在的影响或产生的结果，常与just（刚刚），already（已经），ever（曾经），never（从来），yet（尚，还）等表示时间的副词搭配使用。 Have you ever seen the film?  你看过这部电影吗？ Sh

2、e has already bought a lot of things.  她已经买了许多东西。 （2）表示一个从过去某个时间开始，延续到现在并可能持续下去的动作，常与表示段时间的时间状语连用，这样的时间常用since或for来构成。since后面加时间点或从句（从句的时态常用一般过去时）for后加时间段： He has worked here for 15 years.  他在这里工作了15年了。 I have studied English since I came here.  自从我来这里，一直在学英语。 肯定式，否定式，疑问式如下： I （We, Yo

3、u, They）have read it.  He （She）has read it.  I （We, You, They）have not read it.  He （She）has not read it.  Have I （we, you, they）read it?  Has he （she）read it?  （3）某些非延续性动词即动作开始便终止的动词，在现在完成时中不能与表示一段时间的状语搭配。例如下面这些动词属于非延续性动词，并非不能用于现在完成时，而是不能接由for或since引导的时间状语。die, arrive,

4、 join, leave, go, finish, buy, come lend, borrow, marry, 例如： He has come here for two hours. （×）他来了两个小时了。 He has been here for two hours.  （4）have （has）gone to表示去了某地但还没有回来。have（has）been to表示去过某地并且已经回来。 He has gone to Shanghai.  他到上海去了。 He has been to Shanghai.  他去过上海。 2. 现在完成时与一般

5、过去时的区别： 现在完成时表示过去发生的某一动作对现在造成的影响或结果，强调的是现在的情况，所以它不能和表示过去的时间状语连用。而一般过去时只单纯表示过去的动作或状态，和目前情况无关，它可以和表示过去的时间状语，如yesterday, last year, just now等连用。试比较： It snowed heavily yesterday.  昨天雪下得很大。 It has snowed for three days.  已经下了三天雪了。现在完成时专项练习针对练习基础过关 课堂巩固，基础闯关一、 单项选择。()1、Both  his
