二：时态的变化直接引语变为间接引语时，如果主句是过去的某种时态，则间接引语的时态应相应向前推一个时态，如下所示：一般现在时→一般过去时现在进行时→过去进行时现在完成时→过去完成时一般过去时→过去完成时过去完成时→过去完成时（不变）过去进行时→过去进行时（不变）一般将来时→过去将来（1）如果直接引语中有明确的表示过去时间的状语，变为间接引语时，时态不变。Mymothersaidtome，“Themuseumwaspletelytransformedin2017.”→Mymothertoldmethatthemuseumwaspletelytransformedin2017.我母亲告诉我，图书馆在2017年被彻底改造了。（2）如果直接引语表述的是客观真理，变为间接引语时，时态不变。Thegeographyteachersaidtous，“Theearthtravelsaroundthesun.”→Thegeographyteachertoldusthattheearthtravelsaroundthesun.地理老师对我们说：“地球围绕太阳转。”三：指示代词、时间状语、地点状语和动词的变化（1）指示代词：this→thatthese→thoseHesaidtome，“ThisistheSchoolputerCentre.”→HetoldmethatwastheSchoolputerCentre.（2）时间状语：now→then today→thatdaythismorning/week→thatmorning/week yesterday→thedaybeforeyesterdaymorning→themorningbefore nextweek→thenextweek/thefollowingweeklastweek→theweekbefore twodaysago→twodaysbeforetomorrow→thenextday/thefollowingday thedaybeforeyesterday→twodaysbeforethedayaftertomorrow→intwodays’time（3）地点状语：here→there（4）动词：e→gobring→take

（4）直接引语是祈使句，间接引语变为ask/tell/ordersb.（not）todosth.句式。Hesaid，“Don’tsubscribetoherview.”→Hetoldmenottosubscribetoherview.他告诉我不要同意她的观点。【语法专练】1．Shesaidthattheirtrain______________(arrive)infiveminutes.2．Mymotheraskedme______________Ihadfinishedthehomework.3．TomtoldmethathewouldhelpmewithmyEnglish______________nextday.4．Theteachertoldtheboysandgirlsthatthesun______________(rise)intheeast.5．Theoldmanaskedmybrotherwhathe______________(do)therethedaybefore.6．Thelittlegirltoldhimthatshe______________(watch)thewonderfulfootballmatchthemonthbefore.7．Shesaidthatshe______________(write)aletterwhenheknockedatthedoor.8．Shetoldmethatshe______________(break)myCDplayerbecauseofcarelessness.9．Thismorninghesaidthathe______________leaveforBeijingtomorrow.10．Heaskedushowmanycarfactories______________(build)inourcountrybytheendoflastyear.【答案】1.wouldarrive2.whether/if3.the4.rises5.haddone6.hadwatched7.waswriting8.hadbroken9.would10.hadbeenbuilt【能力目标】交际与运用Ⅰ重点词汇详解1.starvevi.&vt.使挨饿;饿死单句语法填空(1)Whatshockedthescientistswasthattheseal____________(starve)todeathbecauseitcouldn’tfindenoughfoodtoeat.(2)Sheisstarving____________(lose)weightsothatshecanwearthebeautifuldressesthatsheiscrazyabout.【答案】1.starved2.tolose•starvetodeath饿死•bestarvingforsth./todosth.渴望某事/做某事•starvationn．饥饿;饿死完美写作·完成句子·背诵(3)我渴望学好英语，因为掌握英语意味着我们可以通过一个新窗口看世界。IamstarvingtostudyEnglishwell，becausemasteringEnglishmeanswecanseetheworldthroughanewwindow.2seizevt.抓住;夺取;控制先练基础——单句语法填空(1)Thetrafficpoliceman____________(seize)thedriverbythearmandintendedtofinehim.(2)____________(seize)thepreciouschanceenabledhimtogetpromotedquiteeasily.【答案】1.seized2.Seizingseizesb.bythearm抓住某人的胳膊seizeachance/anopportunity抓住机会完美写作·完成句子·背诵(3)鉴于你口语不好，我强烈建议你抓住每个机会说英语。Giventhatyoudon’tgetalongwellwithoralEnglish，Istronglysuggestthatyou(should)seizeeverychancetospeakEnglish.(4)我一看到父亲阴云密布的脸，就感到恐惧。(读后续写之恐惧心理描写)ThemomentIsawmyfather’scloudyface,panicseizedme.3.submitvt.&vi.提交;呈递;屈服单句语法填空(1)Dozensofenterpriseshave__________(submit)theirplanstoreducetheircarbonfootprintinthepasttendays.(2)Inthepast，Ifrequentlysubmittedmyself__________difficultiesbutnowIcansparenoefforttohandlethem.【答案】1.submitted2.tosubmitsth.tosb.将某物提交给某人submit...oneself...to屈从于……完美写作·词汇升级/完成句子·背诵(3)(普通表达)Inspiteofchallengesandhardshipsinmydailylife，Ideclinetogiveintothem.(高级表达)Inspiteofchallengesandhardshipsinmydailylife，Ideclinetosubmittothem.(4)对这次夏令营感兴趣的人必须在5月15日前提交申请书和相关资料。ThosewhoareinterestedinthesummercampmustsubmittheapplicationsandrelevantmaterialsbyMay15.4.toleratevt.忍受;包容;容许单句语法填空(1)Wecan’ttoleratepeople____________(throw)garbagehereandthere，sowewilllaunchacampaigntoappealtopeopletoprotecttheenvironment.(2)Myparentsare____________(tolerate)ofmychoiceofbooksonconditionthatImustmakefulluseoftimetostudyhard.【答案】1.throwing2.tolerant•tolerate(sb./sb.’s)doingsth.忍受(某人)做某事•tolerancen．宽恕;忍耐tolerantadj.忍耐的完美写作·完成句子·背诵(3)那些懂得容忍他人的人会过得幸福。Thosewhoknowhowtotolerateotherscannaturallyleadahappylife.5.onbehalfofsb./onsb.’sbehalf代表/代替某人完美写作·一句多译·背诵我代表我们班，热情、真诚地欢迎你们来到中国。(1)Onbehalfofourclass，IweleyoutoChinawarmlyandsincerely.(2)Representingourclass，IweleyoutoChinawarmlyandsincerely.6.releasevt.&n.排放；释放；发布;Theheatisreleasedbackintospaceatlongerwavelengths.热量以更长的波长释放回太空。releaseaprisoner释放囚犯

alongwithitscausesandimpacts.气候变化需要全世界的关注毫无疑问，地球正在变得越来越暖和(见图表)。2013年，因为一张北极熊尸体的新闻照片让很多人震惊，这只熊似乎是饿死的,

因为冰川融化，北极熊捕猎不到海豹。这一令人震惊的案例表明气温升高对地球生态产生了怎样的影响。气候学家们认为有两大因素导致全球表面平均温度的上升。“自然”温室效应的过程使得地球气候保持温暖和适宜居住，

维持生命成为可能。然而，通过燃烧化石燃料等造成的“人为”温室效应使更多的热量被困在大气中，导致地球表面温度迅速上升。有全面的证据表明，气温上升已导致世界范围内极端天气和自然灾害的增加。新闻报道经常播报

极端暴雨和热浪的新闻,

如果不采取适当的行动，这种变暖的趋势可能会继续下去，付出更高的代价。这需要全世界人民的关注和各国政府需要制定政策并采取适当措施来减少温室气体排放。

作为个人，我们也可以通过限制二氧化碳的量来减少我们的“碳足迹”。我们有责任抓住每一个机会，让每个人了解全球变暖及其原因和影响.Passage2REDUCINGWATERPOLLUTIONINTHELIRIVERThebeautifulLiRiverisoneofthemostwellknowntouristdestinationsinGuangxi,attractingmillionsofdomesticandforeignvisitorseachyear.However,withthegrowthintourism,volumeof
