internet PPT，第二部分内容：课堂篇学习理解重点词汇1.confirm vt.确认;使确信【课文原句】Have you confirmed the WiFi password?你确认WiFi密码了吗?【词汇精讲】confirm是及物动词,意为“确认;使确信”。He looked around to confirm that he was alone.他四处张望,要确定周围没人。The latest developments confirmed me in my belief.最新的发展使我坚定我的信仰。2.discount n.折扣　vt.打折【课文原句】Laura needs an app that will help her get discounts.劳拉需要一个应用程序来帮助她获得折扣。【词汇精讲】discount作名词时,意为“折扣”;作动词时,意为“打折”。The shop owner agreed to allow you a discount.店老板同意给你打折。Tour prices are being discounted as much as 50%.旅游价格打了5折之多。3.account n.账户;描述【课文原句】Laura needs an app that will add money to her bank account.劳拉需要一个能给银行账户存钱的应用程序。【词汇精讲】account作名词时,意为“账户;描述”。作动词时,意为“看作,视为;解释”。The accounts show we have spent more than we received.账目显示我们已经入不敷出了。The girl was too shocked to give an account of what had happened before the attack took place.这个女孩受惊吓太厉害了,以至于无法描述袭击发生前发生什么事了。重点句式This app keeps you updated on all your favourite topics.这个应用程序让你了解所有你最喜欢的话题。【句式剖析】keep you updated是“keep+宾语+宾语补足语”结构,由于update和you有逻辑上的动宾关系,所以用动词-ed形式作宾语补足语。I want you to keep me informed of how things are going with you.我希望你随时告诉我你的进展情况。The man was lying in bed,keeping his eyes closed.那个人躺在床上,双眼紧闭。重点语法现在完成时的被动语态一、现在完成时的被动语态的构成二、现在完成时的被动语态的用法1.表示一个被动动作发生在说话之前,强调对现在造成的影响和结果。The house has been cleaned by my home robot.房子已经被我的家庭机器人打扫干净了。All the preparations for the task have been completed.这项任务的所有准备工作都已完成。2.表示一个被动的动作或状态开始于过去,持续到现在,并可能持续下去,常与for或since引导的时间状语连用,或用于How long...?句型中。How long has the book on computers been kept?这本有关电脑的书借了多长时间了?More than 20,000 computers have been made in the factory since last month.自从上个月起,这个工厂已生产了20 000多台电脑。三、短语动词的被动语态1.短语动词是一种固定的词组,由“动词+副词”或“动词+副词+介词”构成,其作用相当于一个动词。(1)“及物动词+副词”“及物动词+介词”以及“及物动词+副词+介词”构成的短语动词可用于被动结构。At last they put out the fire.→At last the fire was put out.Have you sent for a doctor?→Has the doctor been sent for?My classmates caught up with me in this exam.→I was caught up with by my classmates in this exam.(2)许多“不及物动词+介词”以及“不及物动词+副词+介词”构成的短语动词相当于及物动词,也可以有宾语,也可用于被动结构。The boys laughed at him for the foolish mistake.→He was laughed at for the foolish mistake.注意:短语动词是一个不可分割的整体,在变为被动语态时,不可丢掉构成短语动词的介词或副词。We must take good care of the young trees.→The young trees must be taken good care of.2.带有双宾语的句子在变为被动结构时,这两个宾语的任何一个都可作被动句的主语。(1)把间接宾语改为被动语态的主语,直接宾语仍保留原位。(2)把直接宾语改为主动语态的主语,此时,间接宾语前要加介词to或 for。He gave the boy an apple.→The boy was given an apple./An apple was given to the boy.Her father bought her a present.→She was bought a present by her father./A present was bought for her by her father.3.带复合宾语的动词在改为被动语态时,一般把主动语态的宾语改为主语,宾语补足语在被动语态中作主语补足语。We call him Xiao Wang.→He is called Xiao Wang.He cut his hair short.→His hair was cut short.注意:主动语态中不带to的动词不定式作宾语补足语,改为被动语态时不定式前要加to。They watched the children sing that morning.→The children were watched to sing that morning.随堂练习Ⅰ.单词拼写1.A new machine has many separate parts,each performing a different ________(功能).答案:function2.It has been________(确认) that the meeting will take place next
