UNIT 1 Topic 1 语法精讲 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. 明天下午我们学校将有一场足球赛。（已有告示）　　I feel terrible.I think Im going to die. 我感到难受极了，我想我快不行了。　　Look at those black clouds！Its going to rain. 看看那些乌云！天快要下雨了。　　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：　　He isnt going to see his elder brother tomorrow. 他明天不准备去看他哥哥。　　Mary is going to be a teacher when she grows up. 玛丽决定长大了当一名教师。　　3. 只是单纯地预测未来的事，此时可与will互换。例如：　　I think it is going to/will rain this evening. 我认为今晚要下雨。　　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？ ——谁能帮我一下吗？　　—I will. ——我来。（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，youd better take your coat with you. 你若今晚去看电影，最好带着外套。　　be going to也常可以用于主句之中。例如：　　If you invite Jack，theres going to be trouble. 如果你邀请杰克，那就要惹麻烦了。　　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。例如：　　If you will learn to play football，Ill help you. 如果你想学踢足球，我可以帮你。Be careful.
