The present continuous 现在进行 ，

going to （do）打算去做 ，

will 将要去做

1、We use the present continuous to talk about plans and intentions，when we have decided in the past about an action in the future。

Example：I am going to work hard next year。（打算怎么样？）

（I thought about it in the past and made a decision before now）

2、We use will when we decide something at the moment of speaking，not before。

Example：A：Would you like a drink？B：Yes，please，I will have a coffee。

3、We use going to do to talk about plans and arrangements we have made in advance with other people。

Example：I am going to have lunch with Jenny tomorrow。

（I phoned her yesterday and we made the arrangements）
