In this lesson, I will show you the use of volitional form in conjunction with とおもっています.

When you use the volitional form plus とおもっています, you can express your willingness or decision.

きょう　なに　を　たべます　か。

What are you going to eat today?

ハンバーガー　を　たべよう　とおもっています。

I'm going to eat a hamburger.

ハンバーガー　を　たべよう　とおもいます。

I'm going to eat a hamburger.

*When you use おもっています, it tend to imply that the decision has been already made. 

*When you use おもいます, it implies the decision has been just made at the time of speaking. 

ハンバーガー　を　たべる　とおもいます。

I think I will eat a hamburger.

よるごはん　は　なに　を　つくります　か。

What are you going to cook for dinner?

カレー　を　つくろう　とおもいます。

I'm going to cook curry.

カレー　を　つくろう　とおもっています。
