You always look unhappy ！What （worry） you？
I really can't balance my study and hobbies．
The librarian was at me and seemed friendly． （smile）
Dad them to our house and Mum soon had a lunch ready for them．（bring）
Tom is thinking about going as a cowboy for the year at Halloween． （five）
There is a place in my heart where all nations will live some day． （peace）
