Are you going to play basketball after class? b. 表示有迹象即将要发生什么事 Look at those black clouds. It is going to rain.

She will get better. 2）will表示将来，通常是指事先无计划的意图，是临时决定的； be going to则表示事先有计划的意图，是经过考虑的。 — George phoned while you were out. — Ok. Ill phone him back. — Matthew phoned while you were out. — Yes, I know. Im going to phone him back. 3）表示有迹象显示将要发生某一动作时，要用be going to，不用will或shall。 I feel terrible.
