从属连词，表示“假如”“如果”时，

引导条件状语从句。Ifit

doesn‘t

rain,wewillgototheparknextSunday.if引导条件状语从句在时态上遵循以下原则：1、主将从现（主句为一般将来时,从句为一般现在时）；Ifitrains,Iwillstayathome.2、主情从现（主句含有情态动词，从句为一般现在时)；Ifyoudrivetoofast,youmayhaveanaccident.3、主祈从现（主句为祈使句,从句要用一般现在时态）；Don'tplaycomputergamesifyoudon'tfinishyourhomework.(从句)(主句)if的用法重点词汇复习●if做“是否”解释，引导宾语从句，后跟陈述句的语序，表疑问。HeaskedifIhadleftwithyou.if引导宾语从句在时态上遵循以下原则：1、主现从任（主句为一般将来时,从句可以用任何时态）；MyteachertellsmethatJohngotanAintheyesterday'sexam.2、主过从过（主句为过去时态,从句要用过去的某种时态)；MyteachertoldmethatIhadpassedtheexam.3、主任从现

youwon'tcatchifgets根据句意可知，此处是if引导的条件状语从句，时态根据“主将从现”原则，所以主句用一般将来时，从句用一般现在时表示将来。if/whether

was根据句意可知，此处的直接引语是一个一般疑问句，所以连词用if/whether,主句是一般过去时，所以be动词用过去式was。4.—Iamworriedabout
