Iwillhaveagoodtimetomorrow.Iwillgotothepartytomorrow.IfIgotothepartytomorrow,I’llhaveagoodtime.合并GrammarFocus:if条件句if引导一个条件状语从句时，当主句是一般将来时时,if引导的从句必须用现在时来表示将来可能发生的动作或存在的状态。
在英语里,当句子的主句为将来时态时,它所引导的时间状语从句和条件状语从句都使用一般现在时来表示将来时间,这在英语里被称为“主将从现”。主句的将来时态并不仅限于我们这一课里所学习到的will＋动词原形构成的一般将来时,还包括begoingto＋动词原形、bedoing所表示的一般将来时以及我们以后会学到的其它的将来时态。例如:
►Whatishegoingtodowhenhegrowsup?他长大了想干什么？►WeareleavingforXiamentomorrowifitdoesn’train.如果明天不下雨,我们就去厦门。►Wewillbuythatmicrowavenextweekifitspricekeepsgoingdown.如果价格持续下降,下个礼拜我们就买那台微波炉。
If+…,I’ll/you’ll+…↘↙↘↙条件结果1.结构Forexample:Ifyoustudy,I’llbehappy.wearjeanstoschool,you’llbesorry.getuplate,you’llbelate.eattoomuch,you’llbefat.washyourclothesyourself…
有时，我们可以使用并列结构的祈使句来表达if引导的条件句。如：Ifyousetyouralarmclock,youwon’toversleep.如果你上闹钟,你就不会睡过头了。Setyouralarmclock,andyouwon’toversleep.
►Ifyougivehimaninch,hewilltakeamile.他会得寸进尺。►Givehimaninch,andhewilltakeamile.►Ifyoudon’tgivehimsomefood,hewillstarve.如果你不给他一点吃的,他就会饿死。►Givehimsomefood,or/elsehewillstarve.
2.用法(1)条件状语从句通常由连词if引导,意为“如果、假如”,主句不能用begoingto表示将来,而应该用shall,will。e.g.Ifyouleavenow,youarenevergoingtoregretit.(错误)Ifyouleavenow,youwillneverregretit.(正确)(2)if“如果”,引导条件状语从句,主句用一般将来时,从句则用一般现在时，如：Ifitrainstomorrow,Ishan’tclimbthehills.
注意:宾语从句中的if与条件状语从句if的区别。宾语从句中的if“是否”相当于whether,引导宾语从句,时态需根据语境确定。Idon’tknowifitwillraintomorrow.我不知道明天是否会下雨。
在阅读英文文章时,我们有可能看到这样的句子：Ifmyfatherwillgivemepermission,Ishallspendafewmonthsabroad.如果我父亲同意,我将在国外待几个月。Ifyouwilltakethetroubletoreadhislettercarefully,youwillseewhathemeans.如果你肯花一些时间来认真读他的信，你就会明白他是什么意思了。在if-分句中用“will＋动词原形”并不单纯表示将来意义，这里的will是个表示“意愿”的情态动词,相当于bewillingto(愿意)。
要注意这种带“will＋动词原形”的if-分句在某些场合是不可以随便用的,比如我们可以说：Ifhegetsmyletterintime,he’llbeabletochangehisplans.如果他及时收到我的信,他就能改变他的计划。却不可以说成：Ifhewillgetmyletterintime,he’llbeabletochangehisplans.
IfyouwouldtryItalianfood,youwouldlikeit.如果你愿意尝尝意大利食物,你会喜欢它的。Ifyouwouldreservetheseats,wewouldbesureofacomfortablejourney.如果你愿意订座,我们将肯定会有一个舒适的旅程。

1.be＋doing形式:用现在进行时态表达将来，主要意义是表示按计划、安排即将发生的动作，常用于位置转移的动词,如go、come、leave、start、arrive等,也可用于其它动态动词。如：ThepresidentiscomingtotheUNthisweek.总统这周将到联合国来。Wearemovingtoadifferenthotelthedayaftertomorrow.我们后天将换一家宾馆。拓展
在英语中,有相当多的动态动词都可以用现在进行时表示将来。例如：Dinnerisready.We’rehavingfishfordinner.晚饭好了,今晚我们吃鱼。I’mspendingmyholidaysinSingaporethisyear.今年我要去新加坡度假。Tomisn’tfinishinghishighschooluntilnextyear.汤姆明年才高中毕业。
Canyougivemesomeadviceplease?advice意为“劝告；建议”是不可数名词，不能说anadvice,而应说apieceofadvice。“两个（则）建议”，我们通常说twopiecesofadvice。注意piece要采用复数，advice不可数，但piece可数。我们也可以说somepiecesofadvice一些建议。如：Canyougivemesomeadvice?你能给我一些建议吗？Languagepoints
