since
for
for后面应该接“段时间”；
since后面应该接“点时间”或者“句子”。
关键点：
　１、知道什么是“段时间”或者“点时间”；
　２、since引导的从句通常采用“一般过去时”
Game 2 : 火眼金睛－改错
１. Where have you ever gone The Lantau Island .
２.We have been to the USA for many years .
３.-How many times have you been in Hong-shan Zoo -Twice .
4.- Where is your mother - She has been to America.
-----
been
--
in
--
to
-----
gone
　
1、知道have/has been（to）、gone（ to）、been （in）三者
之间的根本区别：
have/has been to 表示当事人曾经去过某地
have/has been in 强调当事人在某地待过一段时间
have/has gone to 说话时当事人不在现场，去了某地
2、三者的常见用法
been (to) + 地点+次数
been (in) + 地点 + 段时间/句子
gone (to) + 地点
3、共同点
当后跟地点是副词时，介词省略
Game 3:
1.He _________ (know) the city since he was very young .
2. _____ you ____ (see) my watch Yes,I ___ (see)it on your desk five minutes ago .
3. Last night ,it ______ (rain) heavily .
4. --When _____ you _____ (finish) your work
-- Half an hour ago .

Have
seen

finish
１、了解一般过去时与现在完成时最基本的区别是
一般过去时强调动作发生的时间
现在完成时侧重动作的结果
2、牢记现在完成时不能与表示过去的时间连用，
包括疑问词when
3、知道现在完成时的两种特点
（1）：过去对现在 （瞬间性动词）
（2）：过去到现在（延续性动词）
Game 4:
1.The boy has already gone home . （改为一般疑问句）
___________________
2. The girl has just given it to me . （改为否定句）___________________________
3.They have ever visited the Lantau Island before .（改为否定句）
——————————————————————
Has the boy gone home yet
The girl hasn’t given it to me yet
They have never visited the Lantau Island before
1、（现在完成时）肯定句变为否定句的基本方法：
２、（现在完成时）肯定句变为一般疑问句的基本方法：
３、注意点：
１、句中有ever直接将ever变为never
２、若无ever，在助动词have／has之后加not
将助动词have／has提前到句首
just、already、yet之间的关系以及各自适应的句型
　　
除了上述结论之外，你认为现在完成时的运用还需要注意哪些问题？愿意共享你的成果吗？
