I played a country girl in my last (B) movie. I had to live in a small village with the other actors for part of the winter. (C)It was really hard for me as I grew up in a city.

I wanted to understand how a real village girl lived. I thought it was fun at first. I felt different after a week or two, though.

She is crying with true feelings!” I called my mum to tell (E) Her about it but my mobile phone (手机) wouldn’t work in the village.
