Grammar
一、关系代词
1.that既可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语也可以省略。[eg:thisisyourbook(which)youwant。]而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置
2.which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢
3.代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括当先行词是anything,everything,nothing,few,all,none,little,some等不定代词时,或者是由every,any,all,some,no,little,few,much等修饰时等,这时的that常被省略还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that
4.who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语
二、关系副词
关系副词=介词+关系代词
why=forwhich
where=towhich
when=duringwhich
whose=ofwhich
1.where是关系副词,用来表示地点的定语从句
2.when引导定语从句表示时间[注]值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导
BythetimeyouarriveinLondon,wewillhavestayedtherefortwoweeks.IstillrememberthefirsttimeImether.Eachtimehegoestobusinesstrip,hebringsalotoflivingnecessities,suchastowers,soap,toothbrushetc.
3.whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物,当它引导的从句修饰物体时,可以与ofwhich调换,表达的意思一样.
4.当从句的逻辑主语是some,any,no,somebody,anybody,nobody,something,anything,everything或nothing时,常用thereis来引导
Thereissomebodyherewhowantstospeaktoyou.这里有人要和你说话

古人云,工欲善其事,必先利其器。教师在教学前就要准备好教案,做好充分的准备。教案可以让讲的知识能够轻松被学生吸收,帮助教师有计划有步骤有质量的完成教学任务。教案的内容要写些什么更好呢?下面是由小编为大家整理的“高一必修2 Unit4 Wildlife Protection教案分析”,供您参考,希望能够帮助到大家。
高一必修2Unit4WildlifeProtection教案分析
学校:xx十中
姓名:周x
课题:高一人教版课程标准试验教材必修2Unit4WildlifeProtection
教材分析:
本单元围绕“野生动物保护”这一中心话题进行听说读写的训练,其中阅读部分“HowDaisyLearnedtoHelpWildlife”描述了一个名叫Daisy的女孩以特殊的方式从濒危动物那里学到了野生动物保护的知识。Daisy的学习方式,方法和过程非常奇幻,她乘着飞毯周游世界,首先来到了西藏,同藏羚羊的对话中了解到了濒危野生动物的现状和原因。然后飞到了津巴布韦通过大象的介绍,明白了动物保护的重要性和措施,最后来到了热带雨林,从猴子口中懂得了保护野生动物还应该关注他们生活的环境,了解他们的习性。最后Daisy在奇幻之旅结束时提高了保护野生动物的意识,表达了她的感受和决心。文章立意新颖,近似于童话,活泼有趣,行文结构清晰,层次分明。
设计思路:
学生阅读的过程就是随着Daisy学习动物保护的过程。学生是以听说读写的方式从课本,网络等课程资源中获取关于动物保护的信息。基于课文的形式和内容特点,我挖掘出了课文内容与学习方式的结合点,学习内容与实际应用的共性,因此采取了任务型教学的模式,制定出班级总任务是制作以保护各种濒危野生动物为主题的,题为“Let’sHelpWildLife”的英文网站。这个网站是由若干网页组成,网页内容是以一种濒危动物的保护为主题,因此把全班以四人为一组分成若干组,小组任务是制作这张网页。
要完成任务,学生必须确定濒危动物是什么,内容和语言,以及设计制作,具体步骤是课前分组查找濒危动物有哪些,自主选择他们最关注的一种动物,课上学习与主题相关的内容,进行语言聚集,课后收集,整理,合成信息,完成网页的制作,这样,从课前准备到课中学习到课后延展,达成了知识的系统性,提高了学生用英语解决实际问题,综合运用语言的能力,提高了自主学习的意识和能力。
学情分析:
所授课学生为我校高一学生,经过第一模块的学习,学生了解并学会了运用以小组合作的方式进行合作学习,学生具备基本的阅读能力,阅读技巧和方法。但尚未掌握有效的方法克服阅读中的生词障碍。濒危野生动物保护是学生熟悉和关心的话题,但用以表达话题的语言积累不足。此外,虽然学生的学习资源丰富,但未能恰当的利用资源进行语言学习。因此设计好学习任务,方法和步骤是提高阅读能力,进一步巩固和加强英语学习策略的关键。
教学目标:
知识与技能目标:
1.学生通过回答问题,填写图表,连线,等方式获取并理解有关Daisy如何学到的关于野生动物保护知识的信息。
2.能够运用所获取的信息简单描述关于濒危动物,藏羚羊的保护情况。
3.利用资源策略,完成以保护野生动物为主题的网页制作。
情感与态度目标:
1.通过获取野生动物保护知识,提高保护野生动物的意识。
2.通过小组合作,学生提升了合作意识;学生增强了自信,维持并提高了对英语学习的兴趣。
教学重点和难点:
获取并理解关于Daisy学到关于濒危动物保护的知识的相关信息,并迁移运用到谈论关于对藏羚羊的保护。

教学效果评价:
积极开发和合理利用课程资源是英语课程实施的重要组成部分,如何将各种形式的课程资源与英语教材有效的结合是教学过程实施的关键。本课力图将网络资源与教材内容合理地结合,并进行有效的利用和开发。主要体现在以下三点:
1.找到了课本内容与利用网络资源进行课题研究的共性和结合点,即以动物保护为话题的学习。
2.明确了学习课本内容与查找网络信息之间的关系,即互补,互进,互通的关系。因此学生提高了利用课程资源对信息进行有效的筛选和收集的能力。
3.强调了英语教材是英语课程资源的核心部分。学生只有通过课本内容的学习,之后才能确定其网页内容,而且教材为任务的完成提供了充足的语言支持,使学生明确了课本内容,课文阅读,课堂学习的重要性。

Ⅰ.单项填空
1.Itisknownthatwaterisnotanendlessresource,________canitbemadeoncemore,soweshouldsaveandprotectit.
A.soB.as
C.thusD.nor
解析:选D。考查连词。根据“水既不是一种无穷无尽的资源,也不能被再制造”和nor位于句首,句子用部分倒装,可知选D。
2.________,thenorthernerslikenoodleswhilethesouthernersarefondofriceinChina.
A.IncommonB.Ingeneral
C.IntotalD.Inreturn
解析:选B。考查短语辨析。ingeneral总的来说,通常。incommon有共同之处;intotal总共,总计;inreturn作为回报。
3.Smokingisoneofthe________causesofcancer,killingmillionsofpeopleeachyear.
A.majorB.similar
C.commercialD.chemical

5.Ourbodiesarestrengthenedbytakingexercise.________,ourmindsaredevelopedbylearning.

6.Peopleareencouragedtospeakopenly,butcarelesswordsare________tohurtothers’feelings.
A.possibleB.probable
C.likelyD.sure
解析:选C。常用sb./sth.belikelytodo或it’slikely+从句,表示“可能”;certain表示“确定的”;probable后常跟that从句表示“很有可能”;besuretodosth.指“一定,务必去做某事”。
7.Dotellmethewaysyouthinkof________theproblemassoonaspossible.
A.tosolveB.solving
C.solveD.beingsolved
解析:选A。句意:一定要尽快告诉我你想到的解决这个问题的办法。句中youthinkof是定语从句,tosolvetheproblem是不定式短语作定语修饰theways。本题易被错误地分析为thinkofdoingsth.而误选B。
8.Themurdererreached________hisgun,andthenshotattheman.
A.forB.out
C.inD.of
解析:选A。句意:凶手伸手拿起他的枪然后朝那个人开了一枪。reachfor伸手够……,reachout伸出手来,reach与其他选项不能搭配。

父爱无语。离别时作为父亲的“我”该向儿子说些什么呢?简短而又略显不得体的话“假如让我选择的话,我会选择你”让儿子深深地懂得了父子情深。
1.A.experienceB.spend
C.enjoyD.shape
解析:选A。体验一种不同的生活。experience有“经历、体验”的意思。enjoy意为“享受”,不符合语境。
2.A.showB.give
C.makeD.instruct
解析:选B。“我想给他一些有重要意义的话语。”故用give,其他选项不符合语境。
3.A.lastB.first
C.veryD.next
解析:选B。根据下文判断这不是“我”第一次让这种时刻溜走。
4.A.upwardB.into
C.downD.up
解析:选D。根据情景判断,表示“上车”,所以用up。
5.A.signB.scene
C.sceneryD.sight
解析:选B。asimilarscene“类似的一幕(情景)”。
6.A.interestB.instruction
C.courageD.direction
解析:选C。根据所填词的并列项confidence及下文as引导的句子可以判断,此处作者想说点什么以给儿子勇气和信心。故C项符合语境。
7.A.failedB.discouraged
C.struckD.troubled
解析:选A。wordsfailedme相当于“Icouldn’texpresshowIfelt.”意为“我说不出话来”。
8.A.futureB.embarrassing
C.obviousD.lost
解析:选D。根据上下文可知,作者在回忆那些已经失去了的机会。
9.A.lastB.pass
C.flyD.remain
解析:选B。根据第一段最后一句可知答案。pass在此处指(时间)流逝。
10.A.countedB.meant
C.valuedD.cared
解析:选B。mean“意味着”。本句的意思为“我无法找到一个安静的时候来告诉他他对我来说意味着什么。”
11.A.thinkB.want
C.expectD.wish
解析:选C。expect“预料,预计”。think后面不能接动词不定式;want和wish表示主观上的意愿或希望。
12.A.ButB.And
C.InsteadD.So
解析:选A。上文的言下之意是这件事情不重要,这样本句和上文构成转折关系,所以用But。
13.A.wonderedB.regretted
C.mindedD.tried
解析:选B。作者对没有听到父亲对他表达爱的话而感到遗憾,所以用regret。
14.A.viewsB.actions
C.feelingsD.attitudes
解析:选C。把情感(feelings)通过语言(words)的形式表达出来。
15.A.importantB.essential
C.hardD.complex
解析:选C。根据上文判断,作者不知道为什么向儿子说一些肺腑之言如此困难。hard“困难的”,符合语境。essential“必不可少的”;complex“复杂的”。
16.A.disappearedB.changed
C.progressedD.advanced
解析:选A。根据下文的therewerejustDanielandme判断本句表示世界消失(disappear)了。
17.A.sensitiveB.convinced
C.awareD.tired
解析:选C。“我”能感觉到的是……,beawareof“感觉到,意识到”;beconvincedof“相信,确信”;betiredof“对……厌倦”。sensitive“敏感的”,常用besensitiveto意为“对……敏感”。根据语境可知C项正确。
18.A.byB.against
C.onD.with
解析:选B。根据语境“他的脸贴着我的脸”可知,pressagainst“使贴着”符合语境。
19.A.clumsyB.gentle
C.absurdD.moving
解析:选A。根据下文Itwasnothing可知答案。clumsy“笨拙的”。gentle“温柔的”;absurd“荒唐的”;moving“感动人的”。
20.A.noneB.all
C.anythingD.everything
解析:选D。本句和上句构成转折关系(andyet相当于however),所以填everything,和nothing相对应。
