　　現在進行時表將來的用法與一般將來時的區別：

　　(1) 現在進行時表近期的，事先已經計劃安排好的

　　-- By taxi. Bob is coming with me to the airport.

　　(2) will do 和 shall do

　　① 表客觀將來。shall用于第一人稱，will用于第一、

　　二、三人稱。I will / shall finish middle school next month.

　　② 表有科學根據的預測。The weather report says it will rain tomorrow.

　　③ 表客觀必然。Man will make mistakes.

　　(3) be going to

　　① 表現在打算在近期或將來要做某事。I'm going to finish my homework tonight.

　　② 表根據已有跡象的預測。It's so dark outside, I think it's going to rain.

　　③ be going to不與come, go連用，而用be coming, be going 形式。Mary is coming here this evening.

　　[注意]

　　表計劃、安排、規定要做的事，用“be + to do”。此外，表示按時刻表運行的動作常用一般現在時表將來。The meeting is to be held at 9:00 a. m. / Our plane leaves at 6:00 a. m. .
