This Sunday evening ,my family and I decide to go out for dinner,for my little sister had won the first prize in the English competition.We eat Chinese food in the restaurant.We laugh and sing on the way home.All of us had a great time.翻譯成中文這個星期天的晚上，我和我的家人決定外出就餐，因為我的姐姐在英語比賽中獲得了第一名，我們在一家中國飯店吃飯，在回家的路上我們聊天、唱歌，所有人都度過了快樂的時光。補充一下for my little sister had won 里面把had改為have，時態(tài)我弄錯了
