In our junior high school lessons, we often practice using this exercise.
Make a choice between two possibilities and give a reason why. For example:
“Which do you like better?”
A: the summer or B: the winter
I like the summer better, because I enjoy doing outdoor sports, I like the warm weather, and I can make use of the longer days more.
or
I like winter better, because I enjoy playing in the snow, I like wearing big jackets, and I really like the Christmas season!
Obviously the choices could be more specific or at a higher level of difficulty, it is up to you. But I do believe it is a good way to practice your decision making skills in English. Give it a try!
