1. 條件狀語從句中的“主將從現”現象，即主句為將來時態時，它所引導的條件狀語從句使用一般現在時表達將來的意味，這時主句和從句所表達的時態在意義上仍然保持一致。如:IfhegoestoEngland,hewillhavetolearnEnglish.如果他要去英格蘭，他將不得不學英語。Ifitisfinetomorrow,wewillhaveapicnicsomewhere.如果明天天氣好，我們就到什么地方野餐去。這里if所引導的是真實條件句（realconditional），即所假設的條件有可能成為現實，表達假定所假設的條件實現時會出現的情況或會采取的行為。有時，我們可以使用并列結構的祈使句來表達這種類型的條件句。如:Ifyousetyouralarmclock,youwon’toversleep.如果你上鬧鐘，你就不會睡過頭了。Setyouralarmclock,andyouwon’toversleep.Ifyougivehimaninch,hewilltakeamile.他會得寸進尺。Givehimaninch,andhewilltakeamile.Ifyoudon’tgivehimsomefood,hewillstarve.如果你不給他一點吃的，他就會餓死。Givehimsomefood,or/elsehewillstarve.在if-分句中用“will＋動詞原形”并不單純表示將來意義，這里的will是個表示“意愿”的情態動詞，相當于bewillingto（愿意）。要注意這種帶“will＋動詞原形”的if-分句在某些場合是不可以隨便用的，比如我們可以說：Ifhegetsmyletterintime,he’llbeabletochangehisplans.如果他及時收到我的信，他就能改變他的計劃。卻不可以說成：Ifhewillgetmyletterintime,he’llbeabletochangehisplans.另外，在if-分句中還可能使用“would＋動詞原形”的結構，這種用法還是表示“意愿”，常用于表示客氣的請求，這時主句動詞既可以用will/shall＋動詞原形，也可以用would/should/could/might＋動詞原形。如:IfyouwouldtryItalianfood,youwouldlikeit.如果你愿意嘗嘗意大利食物，你會喜歡它的。Ifyouwouldreservetheseats,wewouldbesureofacomfortablejourney.如果你愿意訂座，我們將肯定會有一個舒適的旅程。2. be＋doing形式：用現在進行時態表達將來意味，主要意義是表示按計劃、安排即將發生的動作，常用于位置轉移的動詞，如go，come，leave，start，arrive等，也可用于其它動態動詞。如:ThepresidentiscomingtotheUNthisweek.總統這周將到聯合國來。Wearemovingtoadifferenthotelthedayaftertomorrow.我們后天將換一家賓館。

在現在英語中，有相當多的動態詞都可以用現在進行時表示將來。如:Dinnerisready.We’rehavingfishfordinner.晚飯好了，今晚我們吃魚。

I’mspendingmyholidaysinSingaporethisyear.今年我要去新加坡度假。Tomisn’tfinishinghishighschooluntilnextyear.湯姆明年才高中畢業。2.takeaway“拿走”，“使離開”如:Pleasetake

thatcataway.Ihateanimals.請把那只貓帶走。我討厭動物。What

takesyouawaysoearly?為什么你這么早就走？3.spendtimeawayfromfamily指“不能和家人一起共度時光”。比較常見的用法是spendtimewithsomeone（“和某人一起共度時光”）。如:Iliketospendtimewithmyfriends,justhangingoutorreadingtogether.我愛和朋友一起逛街或讀書來打發時間。

4.realize“實現”，“意識到”如:Workthisway,andyouwillfinallyrealizeyourdreams.就這樣努力，最終你會實現你的夢想。Suddenlysherealizedhowstupidthemistakesshehadmade.突然她意識到她犯了多么愚蠢的錯誤。5.allthetime“一直”如:Conditionsarechangingallthetime.情況一直在發生變化。Sentencesfromthepassage(重點句講解)◆Iwanttoremind
