系动词学习教程.pptx

第1页/共35页英语的动词中，有的后面要接名词或代词等作宾语，有的单独作谓语，而有的动词要接作表语的形容词或名词等。我们把后面接表语的动词称为系动词。最常用、也是同学们最熟悉的系动词就是be；除be以外，表感觉和知觉的动词也可以是系动词。系动词的定义:第2页/共35页look,sound,smell,taste,feel etc.+adj.+like+n.一般现在或过去时(特殊:feel)主动表被动seem,appear,turn out,prove,happen etc.+(to be)adj./n.+to do sth.系动词一般现在或过去时不定式可用各种形式系动词主动表被动不定式可主动或被动become,turn,grow,get,go,come,fall,etc.+adj.+n.注意记忆惯用搭配现在过去将来进行完成时无被动keep,remain,stay,lie etc.+adj.+n.一般现在或过去时无被动第3页/共35页仔细看这些句子:The chocolate cookies smell sweet.巧克力曲奇饼干闻起来甜甜的。He looks angry.他看上去很生气。It tastes delicious.这尝起来味道鲜美。The shirt feels soft.这衬衫摸上去很软。第4页/共35页表感觉和知觉的动词有：look,smell,taste,sound,feel,相当于汉语的“看上去”、“闻起来”，“尝起来”，“听起来”，“摸起来”。注意:这类系动词与系动词be不同，其否定形式和疑问形式的构成要加助动词才行。如：第5页/共35页系动词（连系动词）：它本身有词义，但不能单独作谓语，后面必须跟表语构成系表结构，说明主语的状态、性质、特征等。表感觉和知觉的系动词看起来 look:look smart听起来 sound:sound noisy尝起来 taste:taste delicious摸起来 feel:feel soft闻起来 smell:smell sweet第6页/共35页Complete the sentences with the correct form of the words in the box.(Activity 2)feel look seem smell sound taste1.The milk _ fresh.2.My sweater _ comfortable.3.The room _ quiet.4.These lanterns _ beautiful!5.You _ angry.6.She _ nice.7.You _ happy.8.This pizza _ bad.looks/seems/soundsfeelssoundslooklook/seem/soundsmells/tasteslook/sound/seemsmells/tastes第7页/共35页Look at the picture.Complete each sentence with two suitable words.(Activity 3)1.The cakes _.2.The bananas _.3.The students _.4.The flowers _.taste delicioussmell goodlook happysmell sweetThe party sounds noisy.第8页/共35页Look at the picture.Complete each sentence with two suitable words.(Activity 3)5.The teacher _.6.The juice _.7.The chair _.8.The music _.seems friendlytastes sourfeels comfortablesounds beautiful第9页/共35页第10页/共35页Choose the best answer 1.The water _ cool when I jumped into the pool for morning exercise.A.was felt B.is felt C.felt D.feels 第11页/共35页Choose the best answer2.He shook his head _ and looked _ when he was told the bad news.A.sadly;sadly B.sad;sad C.sadly;sad D.sad;sadly第12页/共35页Choose the best answer3.I love to go to the forest in summer.It _ good to walk in the forest or sit in the shade of trees.A.does B.feels C.gets D.makes第13页/共35页Choose the best answer4.-I was wondering if we could go skating on the weekend.-_ good.第14页/共35页 2.“主观判断”类:包括 seem(似乎是)，appear(似乎、显得)，prove(证明是),turn out(结果是,证明是)等.例如:He appears/seem to be very friendly with us.They appear/seem to have misunderstood me.It appears/seem that she will win.第15页/共35页试比较：He seems(to be)forty.He appears(to be)forty.他似乎四十岁了。（说话人有一定根据）他看上去四十岁。（从外表上看）第16页/共35页Choose the best answer1.His method should be popularized;it _ practical.A.proves B.is proved C.has been proved D.was proved第17页/共35页2.To everybodys great surprise,the fashionable young lady _ to be a thief.A.found out B.proved out C.put out D.turned out第18页/共35页4.John seems _ well at his job.He looks content with it.A.to get on B.to be getting on C.getting on D.to have got on第19页/共35页3.“状态变化状态变化”类类:表示主语从一种表示主语从一种状态变化成另一种状态。状态变化成另一种状态。常见的有常见的有:become,turn,grow,go,come,fall,get 等。等。例如：例如：Put the fish in the fridge,or it will go bad in hot weather.第20页/共35页状态变化系动词第21页/共35页Choose the best answer1.The discussion_ alive when an interesting topic was brought in.A.was coming B.had come C.has come D.came第22页/共35页2.Happy birthday,Alice!So you have _ twenty-one already!A.become B.turned C.grown D.passed第23页/共35页3.The traffic lights_ green and I pulled away.A.came B.grew C.got D.went第24页/共35页4.-Is your headache getting _?-No,its worse.A.better B.bad C.less D.wellTHINK IT THINK IT OVEROVER第25页/共35页4.“状态持续状态持续”类类:表示主语表示主语持续某种某种状态。状态。常见的有常见的有:remain(依然依然)，keep(保持保持)，stay(保持保持)，lie(呈呈状态,置于),continue(继续、仍旧)等。例如等。例如:Why dont you put the meat in the fridge?It will stay fresh for several days.The population growth in China remains a problem.The book lay open on the desk.第26页/共35页Choose the best answer1.-Would you advise me on how to stay_?-Try to live regularly,eat more vegetables and be in a good state of mind.A.health B.healthy C.healthily D.more healthily第27页/共35页2.He kept _ after her,trying to catch her.A.run B.to run C.running D ran 第28页/共35页3.He _in the shade because it was very hot.A.keep B.to keep C.kept 第29页/共35页 remainremain+n.remain+adj.remain+v-ed/ingremain+prep.phraseremain+to do sth.第30页/共35页Choose the best answer1.It is a good plan in theory,but it _ to be seen whether it works in practice.A.waits B.stays C.stands D.remains第31页/共35页2.He remained _ though we repeatly asked him to sit down.A.stand B.to stand C.stood D.standing第32页/共35页3.The true author of the book remains _.A.know B.to know C.unknown D.knowing第33页/共35页第34页/共35页感谢您的观看！第35页/共35页
