only(=if)。注意：條件從句中的if不能用whether替換。e.g.Ifheisnotintheoffice，hemustbeoutforlunch.Youmayborrowthebooksolongasyoukeepitclean.SofarasIknow(據(jù)我所知)，hewillbeawayforthreemonths.Youcangoswimmingonconditionthat(=if)youdon‘tgotoofarawayfromtheriverbank.Ifhehadcomeafewminutesearlier，hecouldhaveseenher.七、讓步狀語從句讓步狀語從句可由although，though，as，evenif(though)，however，whatever，whether……or，nomatterwho(when，what，……)等引導(dǎo)。注意：as引導(dǎo)的讓步狀語從句一般是倒裝的。e.g.Thoughheisachild，heknowsalot.Childasheis，heknowsalot.Whatever(=Nomatterwhat)yousay，I’llneverchangemymind.八、方式狀語從句方式狀語從句常由as，asif(though)，theway，ratherthan等引導(dǎo)。e.g.YoumustdotheexerciseasIshowyou.Heactedasifnothinghadhappened.一、引導(dǎo)名詞性從句的連接詞1.連接代詞：who，whose，whom，what，which.有詞義，在從句中擔(dān)任成分，如主語、表語、賓語、或定語等。2.連接副詞：when，where，why，how.有詞義，在從句中擔(dān)任成分，作狀語。3.連接詞：that，whether，if，asif.that無詞義，在從句中不擔(dān)任成分，有時(shí)可省略;if(whether)，asif雖有詞義，但在從句中不擔(dān)任成分。注意：連接代詞與連接副詞在句中不再是疑問句，因而從句中謂語不用疑問式。連接代詞與連接副詞在從句充當(dāng)句子成分，連接詞whether和if(是否)，asif(好像)在從句中不充當(dāng)句子成分，只起連接作用。根據(jù)句義，如果連接代詞與連接副詞，whether、if和asif都用不上時(shí)，才用that作連接詞(that本身無任何含義)。二、主語從句1.主語從句在復(fù)合句作主語。e.g.Whowillgoisnotimportant.2.用it作形式主語，主語從句放在句末。e.g.Itdoesn‘tmattersomuch
