Unit 7 1. Do you ever worry about failing a test?你曾担心考试不及格吗?worry about意为“担心;担忧”或“为担心”。归纳：worry的用法:worry可作及物动词,意为“使烦恼;使焦虑”,常接sb.作宾语。如:What worried you so much?什么事使你这么着急?His bad health worried his parents greatly.他身体不好使他的父母很发愁。worry也可作不及物动词,意为“烦恼、担心”,常跟介词about或over。如:Tell them not to worry.告诉他们不要担心。They are worrying about the coming exam.他们正在为即将到来的考试而发愁。worry about和be worried about都表示“对担心,忧虑”。例如:Dont worry/be worried about John. Hell be back soon.不必为约翰担忧,他马上就回来。worry后接从句时,也表示“为担心”,此时不用介词,worry可看作及物动词。如:The teacher worried that the exam might be too difficult for her students.这位老师担心此次考试对她的学生来说可能太难了。Dont worry how much you spend.别担心花多少钱。辨析：worried和worrying都可作形容词,前者表示“烦恼的;焦虑的”,常用来说明人;后者表示“令人烦恼的;令人担心的”,常用来修饰说明事物。例如:She seems worried about something.她似乎为某事担心。Theres a worried look on his face.他脸上有一种忧虑的神色。I have never spent a more worrying day.我从未度过如此令人担忧的一天。2. Students need strict rules.学生们需要严格的规矩。strict是形容词,意为“严格的,严厉的”,可作表语也可作定语。如:Our head teacher is very strict,but we still need many strict rules.我们的班主任非常严格,但是我们还需要许多严格的制度。辨析：be strict with和be strict inbe strict with sb.意为“对某人严格要求”;be strict in(doing) sth.意为“对(做)某事严格要求”。例如:Mr. Smith is very strict with his children.史密斯先生对他的孩子们要求十分严格。We should be strict in(doing) our work.对工作我们应该严格要求。3. But sometimes these can get in the way of their schoolwork.但有时这些爱好会妨碍学业。way是名词“道路,方法”,in the way “妨碍,阻碍”,也可用in ones way。如:Youre in my way.你挡住我的路了。辨析：in the way,on the way,by the way,in a way和in this wayin the way挡路;妨碍。例如:Her social life got in the way of her studies.她的社会活动妨碍了她的学习。on the way在路上。例如:Lets wait a few minutes. Hes on the way.咱们等一会儿,他正在路上。(快到了)by the way是个语气词,即“附带说一句”之意。例如:By the way,has everybody arrived?附带问一句,大家是否都到了?in a way某个方面,在某种意义上。例如:In a way,he was right.在某个意义上说,他是对的。in this way用这种方式。例如:In this way you can solve the problem.用这种方式,你能解决问题。4. Teenagers often think they should be allowed to practice their hobbies as much as they want.青少年经常认为他们应该被允许如他们所愿地尽多地实践自己的爱好。as much as意为“和一样多”。其基本结构为:as+ adj./ adv. +as。意为“和一样”,表示同级的比较。使用时要注意第一个as为副词,第二个as为连词。例如:This film is as interesting as that one.这部电影和那部电影一样有趣。Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。归纳其否定式为not as/so +adj./ adv. +as。例如:This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。若有修饰成分,如twice,three times,half,a quarter等,则须置于第一个as之前。例如:Your bag is twice as expensive as mine.你的包比我的贵一倍。5. He is on his school team and has always wanted to be a professional runner when he grows up.他加入了学校赛跑队,并且一直想长大后成为一名专业运动员。(1)grow up “长大;成长”。例如:All plants like to grow up toward the sunlight.所有的植物都喜欢朝着阳光向上长。But what happens when they grow up?可是他们长大了会是什么样呢?归纳grow和up也可构成grown-up,作形容词“长大的”,作名词相当于adult“成人”。(2)该句中的when he grows up是when引导的时间状语从句,主从句的时态要遵循“主将从现”。例如:What will Tom be when he grows up?汤姆长大了做什么?6. My wife and I have supported every one of his races.我妻子和我支持他的每一场比赛。support用作动词,“支持,赞成”,还可指“支撑、给某人(物)以积极援助或支持,养(家);维持(生活);负担(费用)”等。例如:Bill had to support Jill or she would have fallen to the floor.比尔不得不支撑吉尔,否则她会倒在地板上。Our school is supported by the government.我们学校是由政府负担的。His family supported him in his decision.他的家人支持他的决定。归纳support用作名词的不同词意用法:支撑物(可数)。例如:If you dont put a support under that roof it will fall down.如果你没有在屋顶下放一个支撑物,它会倒的。支柱(可数)。例如:I am the only support of my family.我是我们家的唯一支柱。支持(不可数)。例如:The plan was cancelled(取消) because of lack of support.因为缺少支持,计划取消了。辨析：living和support这两者均可表示一个人的谋生方式。其区别是:living是一般用语,泛指“生计”,尤指某人赖以谋生的工作。例如:He earned his living by painting.他靠绘画维生。support指一人对另一人的赡养或抚养。例如:He depended on his parents for support.他靠父母抚养。7. We have nothing against running!我们毫不反对跑步!against是介词,表示“反对”,因为against是介词,所以后接动词时要用动名词。如:Im against doing anything till the police arrive.我反对在警察到达之前采取任何行动。Public opinion is strongly against his visit to the country.舆论强烈反对他访问这个国家。归纳against的用法表示“反对,对着;违反;不利于”等。其反义词为for。若表示“强烈反对”,一般用副词strongly。例如:Are you for or against the plan?你对这个计划是赞成还是反对呢?There were 20 votes for him and 12 against him.有20票赞成他,12票反对他。表示“反对”,经常同那些与之含义相关的动词连用(如:fight,struggle,protest,argue,guard等)。如:The soldiers fought against the enemy bravely.士兵们勇敢地打敌人。He struggled against those who opposed his plan.他同那些反对他的计划的人作斗争。表示位置,意为“靠着;顶着;迎着;衬着”等。例如:The teachers desk is against the wall.老师的办公桌靠墙放着。He stood leaning against the tree.他站着斜靠在树上。易错警醒against是介词,不是动词。如:他靠在树上。正:He leaned against the tree.误:He against the tree.这个计划你是赞成还是反对呢?正:Are you for or against the plan?误:Do you support or against the plan?8. Hes getting older now,so he needs to think about what will happen if he doesnt end up as a professional runner.他在一天天长大,他必须想一想如果他最终不能成为职业选手会怎么样。(1)end up“结束”。end up with后加名词;end up加动词时,用动词的ing形式。例如:Did you end up with a piece of music?你们是以一首音乐结束的吗?We end up talking about the film.我们以谈论电影结束。(2)本句中的what will happen if.意为“如果将会怎样?”使用时注意if后接一般现在时态,为if引导的条件状语从句。例如:What will happen if they have the party today?如果今天开聚会会发生什么事情?归纳What will happen if.也可以缩写成What if。例如:What if she finds out that youve lost her book?如果她发现你把她的书丢了怎么办?What if.表示邀请或建议时,意思是“怎么样?”“如何?”。例如:What if you join us for lunch?同我们一起吃午饭怎么样?9. Maybe he thinks its too strict or unfair.可能他会认为这太严格或不公平。unfair作形容词“不公平”,其同根词为fair“公平的”。例如:The boy thinks his father is unfair to him.男孩认为爸爸对他不公平。归纳加上否定前缀un-构成的同类的词还有:unhealthy不健康的unusual不寻常的unhappy不高兴unable不能的,不会的unpleasant使人不愉快的unimportant不重要的这类词在英语里面,并非否定词,尤其在反意疑问句中值得注意:He is unhappy,isnt he?他不高兴,是不是?例1Oh!Weve just missed the 8 oclock film._.
