my summer break plan

Recently, I feel nervous about my toefl test. because I'm not good at listening, and I fear that I am going to not speak English fluently when the examination. I'm so worried about it. and in these days, I practice my listening everyday. but I also be  afraid I can't pass the toefl test because my poor listening. It's been a long time that I haven't practice my listening. so I think I should cut my summer time of playing outside. and prepare for the TOEFL exam next time, practicing everyday. But I still have a little tim eto go somewhere I want to. The Potala Palace, I think it is the most peaceful place. I want to go there to calm down and have a good rest.
