to do 和和will 的区别的区别1).表示即将要发生某事时，两者意义区别不大，可 互换。一般说来，“be going to”结构通常表示 “较近的将来”，而“will/shall”通常表示“较远 的将来”。What is going to/will happen in your school?I am going to/will climb that hill tomorrow.I think it is going to rain tonight.It will snow in a few days.2).对于事先经过考虑的打算、计划、意图等，应使用be going to,而不是will What are you going to do next Saturday?Im going to visit the Great Wall.对于事先未过考虑的打算、计划，只是临时 起意，通常用will，而不用be going to 结构。这种用法通常见于会话时，乙听了甲的话之 后做出的反应。Where is the telephone book?Ill go and get it for you.3).be going to 表示根据主观判断将来肯定发生的 事情，will 表示客观上将来势必发生的事(will 可表示不以人的意志为转移的自然发展的未 来的事)。He is seriously ill.He is going to die.He will be 20 years old next year.Tomorrow will be Saturday.It will be my birthday tomorrow.4).在有条件从句的主句中，一般不用be going to,而多用will.If it rains tomorrow,Ill stay with you.在宾语从句中，主句将来时多用will/shall，而不用be going to Im sure she will come tomorrow.探究一探究一will和shall表示将来时的用法A Simple future tense with will and shallWe use will or shall when we talk about1 things that are
