1 . Simple Future
The Simple Future has two different forms in English, "will" and "be going to."
Although the two forms can sometimes be used interchangeably, they often express two very different meanings.
These different meanings might seem too abstract at first, but with time and practice the differences will become clear.
Both "will" and "be going to" refer to a specific time in the future. USE 1 "Will" to Express a Voluntary Action "Will" often suggests that a speaker will do something voluntarily.
Examples:
A: I'm really hungry.B: I'll make some sandwiches. A: I'm so tired. I'm about to fall asleep.B: I'll get you some coffee. A: The phone is ringing.B: I'll get it USE 2 "Will" to Express a Promise "Will" is usually used in promises. EXAMPLES: I will call you when I arrive. If I am elected President of the United States, I will make sure everyone has access to inexpensive health insurance. USE 3 "Be going to" to Express a Plan "Be going to" expresses that something is a plan. It expresses the idea that a person intends to do something in the future. EXAMPLES: He is going to spend his vacation in Hawaii. We are going to meet each other tonight at 6:00 PM.USE 4 "Will" or "Be Going to" to Express a Prediction Both "will" and "be going to" can express the idea of a general prediction about the future. Predictions are guesses about what might happen in the future. In "prediction" sentences, the subject usually has little control over the future and therefore USES 1-3 do not apply. In the following examples there is no difference in meaning. EXAMPLES: The year 2222 will be a very interesting year.The year 2222 is going to be a very interesting year. 2.Future ContinuousWe use the future continuous to talk about activities that will be in progress at a certain time:
Like all future forms, the Future Continuous cannot be used in clauses beginning with "when", "while", "before", "after", "by the time", "as soon as", "if" and "unless". EXAMPLES: While I am finishing my homework, she is going to make dinner. Correct While I will be finishing my homework, she is going to make dinner. Not Correct FORM Future Continuous [WILL BE] + [VERB+ing] EXAMPLE: When your plane arrives tonight, I will be waiting for you. [AM / IS / ARE] + [GOING TO] + [VERBing] EXAMPLE: When your plane arrives tonight, I am going to be waiting for you. 7. Which of the tenses below
