thelookofjoyontheirowners*faces.当我看到动物们渐好，看到它们主人脸上喜悦的表情时，我产生出那么一种极强的满足感来。此句中get的两次用法意义各不相同。第一个get的意思是“产生；形成“，为及物动词，常与feeling,idea等词搭配使用。例如：Doyougetthefeelingthatwe'renotwelcomehere?（翻译）你有感觉到这里不欢迎我们吗？第二个get是系动词，后接形容词，表示体质、情绪、天气等方面的改变，通常译作”变得;成为例如:Hegotangrywithmeafterthat.Lastyear,shedecidedtotryoutforavolunteerafter-schoolreadingprogram.去年，她决定参加一个课外阅读项目的志愿者选拔。句中tryoutfor是一个短语动词，意为“报名参加选拔；申请参选（某项活动）为其中一员例如：WhydidyoudecidetotryoutfbrtheOlympics?你为什么要报名参选奥运会？另有短语动词tryout,意为“试验；尝试检验（某种方法或仪器设备的实用性或运作是否正常）”。例如：她喜欢尝试各种新的办法来做事情。（翻译）Sheenjoystryingoutnewwaysofdoingthings.Shestillworksthereonceaweektohelpkidslearntoread.她仍旧在那里一周工作一次帮助孩子们阅读。tohelpkidslearntoread不定式短语作目的状语learntoread是help的宾语【即学即练】根据句意，从方框中选择恰当的单词填空，每词限用一次。satisfaction,several,strong,feelingjoyDon'ttrytogobacktoworkbeforeyouarcphysicallyenough.Itisagoodtobearrivinghomeagain.Jennywashappytoseeme.Shejumpedfor.Wemustdotheworktotheofclients（客户）.Therearebooksonthedesk.Whichonedoyouwant?Answer：1.strong2.feeling3.joy4.satisfaction5.severalStep6Grammarfocus.阅读GrammarFocus中的句子,然后做填空练习。①我想去帮助无家可归的人。I'dhomelesspeople.②你可以请求医院允许你探访儿童并让他们变得更高兴。Youcouldhospitalyouvisitthekidsandcheerthemup.③他自愿一周去那里一次去帮助孩子们学习读书。Shethereonceaweekkidslearntoread.④他决定参加一个志愿者课后阅读节目的选拔。Shetryoutforavolunteerafter-schoolreadingprogram.⑤马里奥相信这会帮助他获得他的梦想工作。Mariobelievesitcanhelphimhisfuturedreamjob.⑥我正在制作一些告示，并将它们张贴于学校里。I'mmakingsomesingsaroundtheschool..学生们根据记忆，看大屏幕来完成填空练习。.学生们完成填空试题后，可以打开课本检查答案，对错误的句子，单独进行强化记忆。Step7NewwordsLookatthebigscreenandlearnthenewwordsandexpressions:raisev.募集；征集e.g.Theysoldsomethingtoraisemoney.他们卖掉一些东西来募集钱。aloneadj.adv.独自；单独e.g.Idon'tliketogooutaloneatnight.我不喜欢晚上独自一人外出。辨析：lonely与alonelonely情感上的孤独，寂寞。alone独自一人（单不定感觉寂寞）。e.g.Lindawasaloneinthehouse.琳达独自一人呆在房子里。Shelivesaloneandoftenfeelslonely.她孑然一身，常感到寂寞。Step8动词不定式用法小结：观察下列不定式在句中的作用。Toseeistobelieve.主语，表语Tomwantstoseeanalien.宾语MybrothergotupearlytowatchthefinalsoccergameonTV.0的状语Hewastooexcitedtosayaword.结果状语Thesadmoviemadeuscry.宾语补主语Itisimportantfbrustodrinkenoughwater.真正的主语Step9Exercises:I.根据句意及括号内所给单词的提示填空。Mr.Millergaveuphisjob(look)afterhissickdaughter.Katewouldlike(be)ateacherwhenshegrowsup.Mrs.Handdidn'tletme(give
