3.“without＋宾语”，有时可以改成条件状语从句。

4.if引导的条件状语从句可以转换为：祈使句＋and＋另一个句子；如果if引导的条件状语从句是否定句，可转换为：祈使句＋or＋另一个句子。用所给词的正确形式填空。2.Ifit____(be)coldtomorrow,Iwillwearmysweater.3.Hecangohomeifhe________(finish)hishomework.finishes1.Putupyourhandsifyou_____(have)anyquestions.haveis3aFillintheblankswiththecorrectformsoftheverbsinbrackets.DearSuMei,Idon’t_______(know)whatto______(do)aboutgoingtoMike’sbirthdaypartytomorrownight.Myparents_______(think)IshouldstudyformyEnglishexamnextweek.IfI______(go)totheparty,they________(be)upset.Mike______(tell)ustowearniceclothes,butIdon’t______(have)any.IfI_______(wear)jeans,I______(look)knowdothinkgowillbetoldhavewearwilllooktheworst.Also,I’mnotsurehowto______(go)totheparty.IfI_______(walk),it______(take)metoolong.IfI_______(take)thetaxi,it_______(be)tooexpensive.Canyougivemesomeadviceplease?Tinagowalkwilltaketakewillbe3bCompletethesentencesusingyourownideas.1.IfIgetuplatetomorrow,_______________2.IfIdon’tfinishmyhomework,__________3.IfIdon’tgetenoughexercise,___________4.Iwillnothaveenoughtimetostudyif_______________________________________5.Iwillnotmakeanyfriendsif____________1.I’llbelateforschool.2.Myparentswillbeupset.3.I’llbecomeveryheavy.4.Iplaychessafterschooleveryday.Possibleanswers5.Idon’tgotomyfriends’parties.Tina’sworries:
