The Present Cntinuus Tense：expressing futurity
现在进行时主要表示现在或目前正在进行的动作，除此之外，还可以表示将来。现在进行时表将来时常有“意图”“安排”或“打算”的含义。归纳总结如下：
1. 现在进行时表将来意义使用的动词常为趋向性动词和表示位置转移的动词，常用的有：arrive, cme, d, get, g, have, leave, meet, play, return, see, spend, start, stay, wear, wrk 等。例如：① Hw are yu ging — by bat r by train? ② I’m meeting yu after class.
2. 现在进行时常表最近或较近的将来，句子里常有一个表示未来的时间状语。例如：① They’re leaving fr Hng Kng this afternn.② What are yu ding next Sunday?
3. 表将来的现在进行时有时含有 “决心”的意思，多用在否定结构 中。例如： I’m nt waiting any lnger.
4. 现在进行时也可在时间、条件或原因状语从句中表示将来。例如： ① When yu are passing my huse, please drp in. ② If they are nt ding it, what shuld I d? ③ Because the bride is cming, all the peple are pleased.
5. 现在进行时表将来与一般现在时表将来的区别在于：用现在进行时表示将来，其计划性较强，并往往暗示一种意图；而一般现在时表示将来，则其客观性较强，即通常被视为客观事实，多指按时刻表或规定要发生的情况。
如果主语是train, cncert, prgramme 等表示事物的名词，动词通常用一般现在时表将来而不用进行时。例如：① I’m nt ging ut fr dinner this evening. ② What time des the train t Mianyang leave?
另外,表示将来的动作或状态, 还可用以下几种形式:
① will / shall＋动词原形 I shall be seventeen years ld next mnth.
② be ging t＋动词原形:表示即将发生的或最近打算进行的事。 We are ging t have a meeting tday.
③ be t＋动词原形:表示按计划要发生的事或征求对方意见。 Are we t g n with this wrk?④ be abut t＋动词原形,表示即将发生的动作,不与表示将来的时间状语连用。
I was abut t g swimming when my guide shuted at me and tld me nt t d s. 我正要去游泳, 这时向导大声叫我不要去。
⑤一般现在时表示将来时(1) 按规定预计要发生的未来动作,仅限于动词cme, g, leave, mve, start, return, arrive, begin, stay等动词. The plane takes ff at 10:10. That is, it’s leaving in ten minutes.
(2) 用在状语从句中用一般现在时代替将来时。 If yu d that again, I’ll hit yu.(3) 用在I bet 和I hpe后面, 常用一般现在时表将来。 I bet yu dn’t get up befre ten tmrrw. 我敢说你明天不到10点是不会起床的。
