She looks tired out.她显得疲惫不堪。 【点拨】tiring表“令人疲劳的”。如： That is a tiring job.那是一件累人的工作。 10.rest休息 Sit down and rest for a while.坐下来休息一会儿。 Lets rest(have a rest)here,shall we?我们在这里休息一下，好吗? 【点拨】take/have a rest=take/have a break休息一下。另外，rest还可以作“其余的”讲。如： The rest of the boys are short. 11.problem问题，习题 Today well think about the second problem.今天我们要思考一下第二道习题。 【点拨】该词的意思是“有待解决的问题”，而question的意思为“有待回答的问题”。 12.fat肥的，胖的 She is a fat girl.她是个胖女孩。 Nobody likes fat now.现在没有人喜欢吃肥肉。 【点拨】该词可作名词，表“肥肉”，反义词是thin。如： My mother is thin,but my father is too fat.我母亲很瘦，但我父亲很胖。 13.thin瘦的，薄的，稀薄的 The ice on the lake is too thin for skating.湖上的冰太薄，不能溜冰。 Mr Johnes is thinner than Mrs Johnes. 14.round在周围 A crowd soon gathered round.不久，一群人就围扰来了。 I looked round the room.我向房子四处看。 【点拨】也可作副词，表“在周围”。如：look round=look around环顾四周。单元词组思维运用 1.every time每次，总是，每当 Every time I do the housework I feel tired.每次我做家务事总感到疲劳。 【提示】time表次数时可数名词。如：three times(三次)。 2.do the washing=do ones washing洗衣服 She helps her grandma do the washing sometimes.她有时帮助她的奶奶洗衣服。 3.look after照顾，照料，照看 My mother is ill in bed,I have to look after her at home.我妈妈卧病在床，我得在家照顾他。 【提示】该词相当于take care of。 4.every five minutes每五分钟 If I work in the garden,I have to sit down and rest every five minutes.如果我在花园里劳动，我得每五分钟就坐下来休息一下。 【提示】类似用法还有：every four(five,six)days每四(五，六)天，every three (four)weeks每三(四)星期，every few days(fours,weeks)每过几天(小时，星期)。另外，every在此表“每(隔)”。注意：every+other+名词时，名词用单数，表“隔一”，如： Write on every other line.隔行写。 5.look over仔细检查 The doctor looked me over carefully.医生为我作了仔细的检查。 6.take exercise运动，进行锻炼 If you dont take more exercise,youll get fat.如果你不多运动，你就会发胖。 【提示】exercise表“锻炼”时，为不可数名词。作具体的测试、学习等练习时，为可数名词。如： Today we have many exercises to do after school.今天放学后我们要做好多练习。二、 学海导航学法指要单元句型思维明晰 1.Theres nothing wrong with Theres nothing wrong with you.你没有很大的毛病。 这个句型既可表“身体不舒服(有毛病)”，也可表某事物有问题(有毛病)。可简单表述为：Theres (was,may be)sth.(nothing,not much,little)wrong with sb.or sth.某事物(或某人)有(没有，没有多大，没什么)毛病。如： Theres nothing wrong with me.我没有什么毛病。 There wasnt much wrong with it.这个东西没有多大毛病。 2.Cant+make it He cant make it today.他今天来不了啦。 1)make it在口语和俚语中是“成功(不论大事或小事都可以用)，做到”的意思。cant make it是“不能及时赴约或某地点”的意思。如第94课的对话中： Jim:Wheres Li Lei? Bill:He cant make it today.He has to stay at home. 当Jim 问：“李雷在哪里?”Bill的回答不能译为：“他今天不能做到，他必须须呆在家里。”而应译为：“今天不来了，他必须呆在家里”。 2)在第22课中：Lets make it half past one中，make it是指“(把时间)定在(什么时候)，”是make it(做到)在具体语言环境中(约会)的具体解释。 make it 3.What do you mean? What do you mean?你(说的)是什么意思? mean在此是动词，意谓“意思是”之意，此句型是常用句型之一，表打算时后跟不定式。如： What do you mean to do?你想干什么? What do you mean by saying that?你说这话是什么意思?单元难点疑点释疑 1.I have to tidy my room.我不得不整理我的房间。 1)have to和must都有“必须，不得不”的意思。但have比较强调客观要求，是客观上的“必须”；而must着重说明主观看法，是主观上的必须。另外，have to随时态、人称的变化而变化，而must则没有这种变化。如： That night we had to walk home because there was no bus.那天晚上我们不得不步行回家，因为没有汽车了。 She must finish his homework before he goes home.她回家之前必须完成家庭作业。 2)tidy the room意为“整理房间”。tidy既可以作动词，也可作形容词。如： Do you often tide your bed?你常整理床铺吗?(tide作动词) Of course.当然。 We must keep the classroom clean and tidy我们必须保持教室干净、整洁。(tidy作形容词) 2.I have to do the washing.我得洗衣服。 do the washing意为“洗衣服”，也可以说成do some washing。类似的词组还有：do some shopping买东西，do some cleaning扫清洁。 3.Why dont you come and play volleyball instead? 1)play volleyball打排球。球类名称前不须加冠词，如：play basketball打篮球，play football踢足球。 2)但在乐器名称前则需加冠词，如：play the piano弹钢琴。妙文赏析(1) Many years ago there lived a doctor in a small town.He was good and kind.He was always ready to go and help people.People always went to him when there was something wrong with them. Many years later,the doctor became old.He began to forget things.People were afraid and didnt go to hime any more.The old doctor asked,“Why does no one come to me now?”No one wanted to tell him why,because they didnt want to hurt the good old man.Instead,they said,“Every body is well in the town now.”The doctor was pleased when he heard that.【赏析】这是讲住在一个小镇的一位年迈的医生的小故事。多年后这位医生因好忘记事情，所以人们不再去向他求医了。但人们为了不伤这位老的感情，就说镇里的人都很健康，所以老人听了非常高兴。这个故事给我们什么样的启示呢?(2)A Housing Problem Sue and Alan had been dating for many years.Every weekend they went to a movie together on Saturday night.On Sundays they went to the beach(海滩)in the summer and to the country in the winter.Sue knew that Alan wanted to marry her,and she wanted to marry Alan ,too.She waited patiently(耐心地)for him to ask her to marry him.However,although he often told her he loved her,he never said anything about marriage(结婚，婚烟),This made Sue unhappy.She was nearly thirty.She believed that if Alan did not marry her soon she might nevery marry.She did not want to be a spinster(老处女).She wanted to have a husband and a family of her own. One evening,as they were walking home after a movie,she said,“Alan,dont you think it is time you asked me something?” Alan thought for a moment.He knew what she was thinking about.At last he said.“Im sorry,sue,but I dont think I have anything to ask you at this time.” “Then I will have to ask you,Alan,”Sue said.“I cannot wait any longer.Im getting old.”She stopped walking and looked at him. “Alan,”she said,“Weve known each other for ten years.I love you and love me.Will you marry me?” Alan took hold of Sues hand.“Sue,”he said,“I want to marry you,but we cannot get married yet.We have nowhere to live.I do not have much money and neither do you.We cannot buy a place of our own.” “That isnt important,”Sue said.“We can live with your parents.” Alan shook his head.“Im sorry but that isnt possible.” “Why not?”Sue asked.“Because my parents are still living with their parents.”he explained.思维体操猜测画线部分的词意： 1.Ten to one the train will be late.
