Translation:My older brother does not like flying.
it accepts "my older brother doesn't like to fly" but not "my older brother does not like to fly" ...
You need more flexibility in your Chinese to English translations. It is frustrating my students!
I agree with DBf9DF these answers are ridiculously narrow and prescriptive - there are many ways of translating these sentences but often there seems to be only one variant that the program will accept. If it doesn't accept reasonable translations after a couple of time I resort to copy and paste.
