教材分析
  本单元课文词汇,内容较浅显,课文亮点不多,建议教师快速处理完课文,把重点放在“环境保护”这个话题以及对第一-------第六单元的复习提高上。
过去分词概念&过去分词作表语,定语:
i.过去分词也是一种非限定动词,一般只有一种形式,但少数过去分词有两种不同的形式,如:
  born(生)——————————borne(负担)
  got(得到)——————————gotten(得到的)
  hung(悬挂)——————————hanged(绞死)
  lit(燃着)——————————lighted(燃着)
  rotted(被腐烂)——————————rotten(腐烂的)
  shrunk(被收缩)——————————shrunken(已收缩的)
  struck(被打击)——————————stricken(被打击的)
  sunk(陷下)——————————sunken(陷下的)
ii.special focus:
  由以上例词可以看出不同形式的过去分词可具有不同的意义。有时二者的用法也不一样。现仅以sunk和sunken为例:
(1)his cheeks have sunk in.
  他的两颊陷了下去。(过去分词sunk是主要动词,与助动词have构成谓语动词)
(2)he was sunk in thought.
  他陷入沉思。(过去分词sunk是非限定动词,用作表语)
(3)the old man has sunken cheeks.
  那位老人的双颊陷了下去(过去分词sunken是非限定动词,相当于形容词,用作定语)
iii.conclusion:
  由此可以看出,作为非限定动词,过去分词sunk与sunken的区别在于:前者的动词性质较强,后者则已相当于形容词。
iv.过去分词也有双重性:
  一方面有动词的性质,另一方面相当于形容词。如:
  (1)i saw the ball thrown into the garden. 我看见那球被扔进了花园。(有动词的性质)
  (2)she’s very worried. 她很担心。(相当于形容词)
v.句法功能:a:过去分词用作表语
  fill in the blank with past participle. pay attention to their meanings.
  a. mistaken b. gone c. broken d. satisfied e. gone
  (1) never touch an electric wire when it is__________. 决不要触摸断了的电线。(表示状态)
  (2) he’s ________________. 他走了。(不久前发生的动作)
  (3) you’re _______________. 你错了。(非永久性)
  (4) are you ___________ that i am telling the truth?你相信我说的是实话吗?(后接that从句)
  (5) _______________are the days when they could do what they liked.
  他们为所欲为的日子一去不复返了。(用作表语的过去分词可用于倒装句中,置于句首)
  (1) c (2) e (3) a (4) d (5)b
  b.过去分词用作定语
  过去分词可用作定语。如是单词,常置于其所修饰的名词之前,如:
  (1) did you pay a visit to the tomb of the unknown soldier?
  你去看了无名英雄之墓吗?(永久性)
  (2) her job was to take care of the wounded soldier.
  她的工作就是照料这个伤员。(不久前发生的动作)
  过去分词短语用作定语时,一般置于其所修好的等词之后,其意义相当于一个定语从句,如:
  (1) trucks and buses were driven on gas carried in large bags on the roof.
  卡车和公共汽车都烧煤气,煤气是装在车顶上的袋中。(相当于:
  trucks and buses were driven on gas which was carried in large bags on the roof. )
  (2) the meeting, attended by over five thousand people,   welcomed the chinese delegation.
  他们举行了欢迎中国代表团的大会,到会的有5千多人。(相当于meeting,   which was attended by over five thousand people, welcomed the chinese delegation. )
词语辨析:
  1. fix, mend与repair
  a.fix“修理,整理”主要指修理机器、表、机件,修补房层、车胎、玩具等。fix常可代替repair。如:
  i am going to have my watch fixed. 我要把我的手表修一修。
  you must get the radio fixed. 你得修一修这个收音机。
  b.mend“修理,修补,缝补”,多指对玩具、衣服、鞋袜等的修补,有时也可指对道路、门窗及电器的修理。如:
  mary is mending her skirt.玛丽正在补裙子。
  he has sent his shoes there to be mended.他把鞋子送到那边补去了。
  c.repair“修,修理,修补”,多指对机械、车辆、无线电、建筑物,道路等比较复杂的修理,对衣服。鞋袜的修补也可用repair,但mend更常用。如
some workers are repairing the road.一些工人在修路。
  has the television set been repaired yet? 电视机修好了吗?
  2.agree的各种搭配
  a.agree with sb.表示“同意某人的意见”;也可接表示意见、想法、观点、决定的词,即 agree with one’s views / opinions / words / what one says / decision等。如:
  she always agrees with us in words but opposes in deeds.她总是口头上赞成我们,行动上反对。
  i completely agree with what you said. 我完全同意你所说的。
  i completely agree with your views on the question.我完全同意你对这个问题的看法。
  agree with还可表示“相一致,符合”(不能用于被动语态)。如:
  the climate here doesn’t agree with me. 这里的气候对我不合适。
  b.agree to,to是介词,后面常跟plan,proposal, suggestion, arrangement等。如:
  we all agree to your proposal. 我们都同意你的提议。
  they agreed to mary’s plan for the summer holidays.他们同意玛丽的暑假计划。
  c.agree to do sth.同意做某事。如:they agreed to leave at   once.
  d.agree on/ upon就……达成协议(双方决定,可用被动语态)。如:
  i don’t agree with you on this problem. 在这问题上,我不同意你的意见。
  we agreed on how to protect the environment. 就如何保护环境一事,我们取得了一致的意见。
  4.“找”search, seek, hunt for, find, find out, look for
  a.search通常指对某处、某地进行搜查或搜索;对人时为“搜身”。常接for构成短语search for,作“寻找;搜寻”解,其对象多为一个或一批人或物,如找矿,找资料,找文件,找工作等。它强调寻找的行为,不着重结果。如:
  the police searched him but nothing was found on him. 警方搜了他的身,但什么也没找到。
  they are searching for the missing child.他们在寻找失踪的孩子。
  b.seek一般用于抽象意义,有时也表示渴望得到某一具体的东西,是比较正式的书面用法。可构成seek for,seek after等短语,作“寻找,设法得到”等解。其后可接动词不定式,此时表示“试图,企图”。如:
  they seek information from various sources. 他们从各种来源收集信息。
  they seek after the truth. 他们追求真理。
  c.hunt for指竭力搜寻,其搜寻对象往往是某种迫切需要的东西或人。如:
  this is just the thing i am hunting for. 这正是我在找的东西。
  they’ve been hunting for you everywhere. 他们一直在到处找你。
  d. look for强调找的过程。如:
  he is looking for his dictionary bought yesterday. 他在找昨天买的那本词典。
  e.find通常强调找的结果。其后可跟名词、复合结构或that从句。如:
  use your head, then you’ll find a way. 开动脑筋,就会有办法的。
  he found his home village unchanged. 他发现家乡还是老样子。
  f.find out通过观察、调查、询问等方式找出(原因等),或发现(秘密、错误)情况等,其后一般跟名词、代词或从句。如:
  have you found out his address? 你查到他的住址了吗?
  please find out when the train leaves. 请打听一下火车什么时候开。
  5. suppose,guess及imagine的用法比较
  a.suppose常指根据一些证据而得出的推断,强调暂时性,可接不定式(特别是to be)、介词短语、形容词等的复合结构,接从句等,作“假定,猜想”等解。如:
  we all supposed him to be an actor.我们都以为他是个演员。
  let’s suppose he is right. 让我们假定他是对的。
  b.guess表达说话人在缺乏了解和证据时所陈述的见解,其后可接名词、复合宾语、从句。如:
  i should guess the old woman to be about sixty.我猜这位老太太六十岁上下。
  guess how much it is worth.猜猜看这东西值多少钱。
  c.imagine指没有充分证据或单凭某种模糊印象和感觉而设想、推断。它跟guess一样,都是缺乏证据的。其后可接名词、v-ing的复合宾语、从句,还可与as连用。如:
  we can hardly imagine life without electricity.我们简直无法想象没有电的生活会怎么样。
  i can’t imagine you/ your living alone in the small mountain village.
  我简直不能想象你竟然独自住在小山村里。
  6.be about to,be ready to的辨析:
  这两个复合助动词都作“乐意”讲,但有区别:前者总是用于肯定结构,而后者则既可用于肯定结构又可用于否定结构。(注:美国英语往往把be not about to作“不愿意”讲。)
  比较:james was about to pay the bill.詹姆斯乐意掏钱付帐。(与 was ready to通用)
  james was not ready to pay the bill.詹姆斯不乐意掏钱付账。(不说he was not about to pay the bill.)
  7.if only,so long as作“只要”讲时的区别:
  a.这两个复合连词同义,都作“只要”讲,但不一定能通用:if only只能连接表达一时动作的从句(参见词条517和519),而as/so long as则限于连接含有“持续”意义或表达存在的从句(参见词条583)。
  例如:if only i have any chance,i shall try again.只要有机会,我将再试它一下。(所连接的从句没有“持续”的含义)
  so long as he remains reactionary,no revolutionary peoplewill take united action with him.只要他保持反动不变,就没有革命人民同他采取联合行动。(所连接的从句含有“持续”的含义)
  so long as there are still many things which we don't knowand in which we lack experience we must be good at learningfrom other countries'strong points.只要我们还有许多东西不懂或缺乏经验,我们就该向别的国家学习它们的长处.(所连接的从句中含有“存在”的意义)
  b.其次,前者多少含有“怀疑”的意境色彩,而后者则没有这种意思。
比较:betty will do the job well if only she works hard.只要贝蒂好好干,她是会把工作搞好的。(多少存有怀疑)
  betty will do the job well so long as she works hard.只要贝蒂好好干,她是会把工作搞好的。(未必有怀疑)
