Have you decided which book to write about yet ? 你决定写哪本书了吗？ which book to write about 写哪本书 “疑问词+不定式”= which book you should write about例: I cant decide when to leave.3.Would you like something to drink? 你想要喝的吗？“to drink”动词不定式做定语。例: Water park is a good place to have fun .水上乐园是一个玩的好地方。 重点语法现在完成时一 基本结构：助动词have/has+过去分词(done) 二句型：否定句：主语+have/has+not+过去分词+其他.一般疑问句：Have/Has+主语+过去分词+其他.简略答语: Yes, 主语 + have/has.(肯定) No, 主语 + havent/hasnt.(否定)三用法（1）现在完成时表示过去发生或已经完成的动作对现在造成的影响或结果 I have spent all of my money (so far).(含义是:现在我没有钱花了.) Guo zijun has (just/already) come. (含义：郭子君现在在这儿)My father has gone to work.(含义是:我爸爸现在不在这儿) （2）现在完成时可以用来表示发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示）常与for（+时间段）,since（+时间点或过去时的句子）连用. for+时段since+过去一个时间点（译为：自从以来）since+时段+agosince+从句（过去时）Mary has been ill for three days. I have lived here since 1998. 四has gone (to),has been (to), has been (in) 的区别Have/Has gone(to) :去了(现在不在说话现场)Where is your father？He has gone to Shanghai. Have/Has been (to) :去过（已不在去过的地方）My father has been to Shanghai. Have/has been in：呆了多久（还在所呆的地方）My father has been in Shanghai for two months. /since two months ago.五现在完成时的标志1.现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义: * 以already, just和yet为标志 He has already got her help.他已得到她的帮助。He has just seen the film.他刚刚看过这场电影。He hasnt come back yet.他还没有回来。* 以ever和never为标志This is the best film I have ever seen.这是我曾经看过的最好的一部电影。He has never been to Beijing.他从没有到过北京。* 以动作发生的次数为标志He says he has been to the USA three times. 他说他已经去过美国三次了。* 以so far（到目前为止）为标+before He has got to Beijing so far.到目前为止他已到了北京。She has passed the examso far.到目前为止她已经通过了考试。2.过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手,进一步学习现在完成时。* for+时段 since+过去一个时间点（过去 从句）为标志注意： 1)现在完成时不能单独与过去的时间状语连用, 如yesterday,last week, three years ago 等; 2)不能与when连用 2.现在完成时往往同表示不确定的过去时间状语连用六过去分词规则动词：规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同： (1)、一般动词，在词尾直接加“ ed ”。 work-worked-worked ,visit-visited-visited (2)、以“ e ”结尾的动词，只在词尾加“ d ”。 live-lived-lived , (3)、以“辅音字母 + y ”结尾的动词，将 y 变为 i ，再加“ ed ”。 study-studied-studied ,cry-cried-cried (4)、重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。 stop-stopped-stopped , drop-dropped-dropped 现在完成时与一般过去时的区别现在完成时与一般过去时都表示“动作已经发生”，但不同点在于：1. 现在完成时强调这一动作与现在的关系，即对现在产生的结果、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。He has learned French for three years.他学法语已经三年了。He learned French for three years.他曾经学过三年法语。Who has taken my bag? I couldnt find it.谁拿走了我的包？我找不到了？He cleaned the house yesterday.他昨天打扫过房间。The room is clean, for he has cleaned it already.房间很干净，因为他已经打扫过了。2. 现在完成时不可与表示过去的时间副词连用，而一般过去时则可以。He did some washing yesterday. 他昨天洗衣服了。【精题演练】1. - Where _you _ (put) the book?
