IfyouwouldtryItalianfood,youwouldlikeit.如果你愿意嘗嘗意大利食物,你會(huì)喜歡它的。Ifyouwouldreservetheseats,wewouldbesureofacomfortablejourney.如果你愿意訂座,我們將肯定會(huì)有一個(gè)舒適的旅程。 DearSuMei,Idon’t______(know)whatto______(do)aboutgoingtoMike’sbirthdaypartytomorrownight.Myparents______(think)IshouldstudyformyEnglishexamnextweek.IfI______(go)totheparty,they________(be)upset.Mike______(tell)uswearniceknowdothinkgowillbeFillintheblankswiththecorrectformsoftheverbsinbrackets.3atold clothes,butIdon’t______(have)any.IfI_____(wear)jeans,I________(look)theworst.Also,I’mnotsurehowto____(go)totheparty.IfI______(walk),it_________(take)metoolong.IfI_____(take)ataxi,it_________(be)tooexpensive.Canyougivemesomeadviceplease?Tinahavewearwilllookgowalkwilltaketakewillbe 1.IfIgetuplatetomorrow,____________________________2.IfIdon’tfinishmyhomework,____________________________Iwillmisstheschoolbus.myteacherwillbeangry.Completethesentencesusingyourownideas.3b 3.IfIdon’tgetenoughexercise,____________________________4.Iwillnothaveenoughtimetostudyif___________________________________5.Iwillnotmakeanyfriendsif____________________________Iwon’tbestrong.Iplaycomputergamesalltheday.Ialwaysmakethemupset. 仿照例子把兩句話合成一句話。Example:a.Youthinkyou’regoingtovisitNewYorkCity.b.Youwillseesometallbuildings.→IfyougotovisitNewYorkCity,you’llseesometallbuildings.Practice 1.a.Youthinkyou’regoingtostudyEnglishhard.b.YouwilldobetterinEnglish.2.a.Youthinkyou’regoingtoeatanddrinkmore.b.Youwillbefatter.→IfyoustudyEnglishhard,you’lldobetterinEnglish.→Ifyoueatanddrinkmore,you’llbefatter. 3.a.Theythinktheyaregoingtodomoreexercise.b.Theirhealthwillbebetter.4.a.IthinkyouaregoingtoletmewatchTV.b.Iwillstayathome.→Theirhealthwillbebetteriftheydomoreexercise.→IwillstayathomeifyouletmewatchTV.
