英語一般將來時態(tài)結(jié)構(gòu)：will / shall＋動詞原形；be going to＋動詞原形；be doing。過去將來時結(jié)構(gòu)：助動詞＋動詞原形；was (were) going to＋動詞原形。

一、一般將來時態(tài)：
四種形式表達將來時: will / shall＋動詞原形, be going to＋動詞原形, be doing,以及一般現(xiàn)在時.
shall / will / be going to +動詞原形
be to do sth.
be +coming (leaving, starting, reaching, returning….)
be about to do sth.
1. will / shall表示單純的將來(即現(xiàn)在的之后),will還可以表示"決心"、"意愿"；shall 用于第一、三人稱的問句中,還可以表示征求對方的意見.例如：
He will be back in a few days.(單純將來)
I will study hard to keep up with my classmates.(決心或意愿)
Shall I go with you?(征求意見)
【注意】在含有if的條件狀語從句時,主句中要用will表示將來時.例如：
If it doesn't rain tomorrow, we will go climbing.
2. be going to＋動詞原形多用于口語,強調(diào)事先的"打算、計劃"要做的事情或有某種跡象要發(fā)生的事情.例如：
What are you going to do this evening?(打算)
Look!There are so many clouds in the sky. It's going to rain, I think. (有跡象要發(fā)生的事情)
3. be doing代表現(xiàn)在進行時.現(xiàn)在進行時表示即將發(fā)生的將來,多與表示位移的動詞come, go, arrive, leave, fly, start等連用.例如：
She is leaving for Beijing. 她就要啟程去北京.
4. 一般現(xiàn)在時表示將來時,主要用于時間狀語從句或條件狀語從句中；或者用來表示按時刻表的規(guī)定將要發(fā)生的動作.例如：
I'll tell him about it as soon as I see him.
My plane takes off at seven tomorrow morning.

二、過去將來時態(tài)：（The Future-in-the-Past Tense)
1)過去將來時一般由“助動詞would(should)＋動詞原形”構(gòu)成,也可以用“was (were) going to＋動詞原形”來表示.過去將來時表示從過去某一時間看將要發(fā)生的動作或存在的狀態(tài),這種時態(tài)常用在賓語從句中.
I thought the film was going to be very interesting.
我原以為這個電影會很有趣.
