将来进行时的特征从句将来进行时，由“will/shall+be+现在分词”构成，表示“将来某个时刻或某一段时间里正在发生的动作”。将来进行时是一般将来时和进行时态的结合体，既有将来的特点，也有进行的特点。其中shall用于第一人称，will通常用于各种人称。常与将来某一个具体的时间连用，如thistimetomorrow，at10o’clocknextMonday等。二将来进行时的用法1.表示将来某一时刻或某一段时间里正在进行的动作。Thistimetomorrow，MarywillbeflyingtoShanghai.明天这个时候玛丽正在飞往上海的途中。Whatwillyoubedoingthistimenextweek?下周这个时候你们将在做什么呢？附：单元语法全解Hewillbevisitinghisparentsthistimetomorrow.明天这个时候他正在看望他的父母。ItwillberainingwhenwearriveinLondon.我们到达伦敦时天将正在下雨。Wewillbeseeingmuchmoreofthisinmonthstocome.在接下来的几个月里，我们将看到更多这样的情况。2.表示将来按照计划在做的事情。Wewillbehavingameetingtodecidewhattodo.我们将开会决定该做什么。Ishallbewaitingforyouinmyroomaftersupper.晚饭后我会在我的房间里等你。Ican’tseeyouofftomorrow.I’llbehavingatalkwithouropponent.明天我不能给你送行，我要与我们的对手谈一谈。Wewillbetakinganexaminationnextweek.我们下周要考试。Iwill/shallbeseeingafriendtomorrow.我明天要去见一个朋友。3.表示将来不一定正在进行的动作。如果句中没有具体或确切的表示将来的时间状语（如thistimetomorrow），或者根本就没有表示将来的时间状语，那么，将来进行时往往表示将要发生的动作，跟一般将来时相差无几。They’llbetravellingtoMarsandback.他们将去火星旅行，然后返回。It’sgreattoknowthatsomeonefamouswillbereadingmystory!某个名人将会读我的故事，真是太棒了！Ifyoutakethatroute，youwillbegoingthelongwayround.如果你走那条路，你就绕远了。Theinternationalcommunitywillbewatchingandwaitingtoseewhathappensnext.国际社会将会对接下来发生的事情拭目以待。◆本书观点

1.英语有一个发展趋势，在很多时候willbedoing可以用来取代willdo，表示纯粹的将来，这是因为表示将来的助动词will，也可以是情态动词，表示意愿或请求。所以，为了区分will表示将来和意愿的差别，我们用willbedoing表示纯粹的将来。willdo可能表示将来，也可能表示意愿或请求，会产生歧义。试比较：Iwillbediscussingtheproblemwiththem.我将要和他们讨论这个问题。Iwilldiscusstheproblemwiththem.我将要和他们讨论这个问题。（还可表示意愿：我愿意和他们讨论这个问题）WillyoubecomingagainnextSunday?下星期天你还来吗？WillyoucomeagainnextSunday?下星期天你还来吗？（还可表示请求：下星期天你再来好吗？）

2.终止性动词（包括“位移动词”）的将来进行时，不表示动作在将来某个时刻或某一段时间里正在进行，而是将来发生。这些动词表示的动作一旦发生即刻终止，所以没有进行的含义。HewillbeopeningasmallbookstoreinMay.他将在五月份开一家小书店。Mrs.Smith，whohasalotofteachingexperienceatjuniorlevel，willbejoiningtheschoolinSeptember.史密斯夫人将在九月份加入这所学校，她在初级教育方面颇有经验。Thetrainwillbearrivinginafewminutes.列车几分钟后就到达了。Pleasesaydefinitelywhetheryouwillbecomingornot.请说清楚，你来还是不来。

以上例句，可以改为一般将来时，意思不变。三关于am/is/aregoingtobedoing结构表示的“将来进行时”

am/is/aregoingtobedoing是willbedoing的口语体，在一些英文电影、戏剧的对白中，我们会经常听到。有些例句牛津词典也已收录，这种结构也表示将来正在进行的动作。例如：Whatareyougoingtobedoingthisafternoon?你今天下午准备做什么？Wearegoingtobedoingalotofhikinginthejungle.我们会在丛林里做许多徒步旅行。I’mgoingtobehostingacostumecontest.我将要主持一场时装比赛。We’regoingtobemeetingthereonaregularbasis.我们将定期在那里见面。Asyouprobablyknow，I’mgoingtobechangingmyjobsoon.你或许知道，我不久就要换工作了。该结构常用来描述场景和一些活动。例如：1.WhenIarriveattheparty，everybodyisgoingtobecelebrating.Somewillbedancing，othersaregoingtobetalking.Afewpeoplewillbeeatingpizza，andseveralpeoplearegoingtobedrinkingbeer.Anyway，they’redoingthesamething.当我到达宴会时，大家都在庆祝。有些人在跳舞，其他人在交谈。几个人在吃比萨饼，还有些人在喝啤酒。总之，他们在做同一件事情。2.WhenTomgetsup，hismotherisgoingtobecookinglunch，hissisterisgoingtobereadingbooksandhisfatherisgoingtobefixinghiscar.Besides，hisdogwillberunningaroundtheyard.汤姆起床时，他妈妈在做午饭，他妹妹在看书，他爸爸在修车。另外，他的狗会在院子里跑来跑去。我们知道，begoingtodo主要表示两种含义。第一，表示句子主语主观打算做某事；第二，表示根据目前的迹象预测某事会在将来发生。那么，如果不定式用了进行体，即begoingtobedoing，就可以排除“打算”这个情态意义，只表示将来意义。例如：Heisgoingtobewearingadecentsuitattomorrow’snightparty.=Hewillbewearingadecentsuitattomorrow’snightparty.=Hewillwearadecentsuitattomorrow’snightparty.（will不表示意愿）他将在明天的晚会上穿上像样的西装。
