Shall I get your coat for you?
二．be going to＋动词原形
1. 表示说话人根据现在已有的迹象，判断将要或即将发生某种情况。这类句子的主语可以是人，也可是物。例如：
There is going to be a football match in our school tomorrow afternoon.
Look at those black clouds ! It’s going to rain.
2. 表示主语现在的意图或现已作出的决定，即打算在最近或将来进行某事。这种意图或决定往往是事先经过考虑的。例如：
Mary is going to be a teacher when she grows up.。
3. 只是单纯地预测未来的事，此时可与will互换。
I think it is going to/will rain this evening.
注意：（1）be going to和will在含义和用法上略有不同。be going to往往表示事先经过考虑的打算；will多表示意愿、决心。两者有时不能互换。例如：
He is studying hard and is going to try for the exams. 他正努力学习，准备参加考试。（不能用will替换）
—Can somebody help me?？
—I will.（不能用be going to替换）
（2）在if之后，通常不用will表示预言，但可以用be going to表示意图。例如：
If you are going to go to the cinema this evening , you’d better take your
coat with you.
be going to也常可以用于主句之中。例如：
If you invite Jack , there’s going to be trouble.
如果表示将来的意愿，will可用于条件从句。此时will为情态动词。
If you will learn to play football , I’ll help you.
