There are so many clouds in the sky. It’s going to rain. （看！天空有那么多云，我想要下雨了。） Grammar Review 两者有时可以通用，只是单纯地预测未来的事，此时可与will互换。如： I think it is going to/will rain this evening. 我认为今晚要下雨。 1.当表示主观方面“打算，准备” 去做什么事情的时候，往往用be going to +动词原形，而will 则多用来表示纯属客观的将来。 2. be going to+动词原形可表示事先计划的意图，而will 则表示说话人当时决定的意图。 但两者有时有区别: 注意：will(shall)+ do+sth与 be going to + do+sth两种句型表示将来的区别 Grammar Review Ⅲ.There be 句型的一般将来时： 肯定式：There is/are going to be+sth. 否定式：There is/are not going to be+sth. 一般疑问式：——Is/Are there going to be+sth? (肯)——Yes, there is/are. (否)——No, there is/are not. 1.There is/are going to be 2. There will be 肯定式：There will be+sth. 否定式：There will not be+sth. 一般疑问式：——Will there be+sth? (肯)——Yes, there will.
