意為“如果”，引導條件狀語從句時，既可放在主句前面，也可放在主句后面。若if條件句放在句首，從句后面要加逗號與主句隔開。Ifyougothere,I’llgo,too.如果你去那兒，我也會去。Mymotherwilltakemetotheparkifsheisfree.如果我媽媽有空，她就會帶我去公園。2.時態(tài)：(1)

主句是一般將來時，if從句用一般現(xiàn)在時表示將來。Ifhecomes,hewillbringhisviolin.如果他來，就會帶上他的小提琴。(2)

主句用情態(tài)動詞表示可能的結果時，if從句用一般現(xiàn)在時。Ifyouwanttoloseweight,youmusteatlessbread.如果你想減肥，就必須少吃面包。Youcangetgoodgradesifyoustudyhard.如果你努力學習，就可以取得好成績。(3)

主句是祈使句時，if從句用一般現(xiàn)在時。Ifyouarenotstrongenough,pleasedon’ttakepartinsuchanactivity.如果你不是很強壯，請不要參加這種活動。3.句型轉換：(1)

if引導的條件狀語從句可與“祈使句+and/or+陳述句（一般將來時）”轉換。其中，在句意上and表示順承；or表示轉折，意為“否則”。Ifyouworkhard,you’llpasstheexameasily.=Workhard,andyou’llpasstheexameasily.努力學習，你將很容易通過考試。(2)

借助without或with來轉換條件狀語從句。Ifthereisnoairorwater,peoplecan’tlive.=Peoplecan’tlivewithoutairorwater.如果沒有空氣和水，人們將無法生存。Ifyouhelpme,I’llfinishtheworksoon.=Withyourhelp,I’llfinishtheworksoon.如果你幫助我，我將很快完成工作。if引導的從句類型的區(qū)分及詞義的區(qū)分1.動詞+if+賓語從句，if翻譯成“是否”，時態(tài)按賓語從句的時態(tài)規(guī)律進行選擇—DoesTimtellyouifhe________tomorrow?—No,hedoesn’t.Butifhe________,I’llcallyou.A．willcome;willcome B．willcome;comesC．comes;comes D．comes;willcome2.主句+if+條件狀語從句，if翻譯成“如果”，時態(tài)遵循“主將從現(xiàn)”原則。Iwillgotothepartyifheinvitesme.如果他邀請我，我就會去參加晚會。Pleasecallmeatonceifhecomesback.如果他回來了請立刻給我打電話。注意：if/when引導狀語從句和賓語從句這時，從句的時態(tài)：ifWhenif/when從句的時態(tài)條件/時間狀語從句如果、假如當……的時候一般現(xiàn)在時賓語從句是否什么時候一般將來時真題感知1．（2023·湖南湘西·統(tǒng)考中考真題）Wildanimalswillbeingreatdanger________weprotectthemtogether.A．if
