【正确答案】：
HE STOOD IN FRONT OF US FOR A MOMENT AND THEN GESTURED US TO GO INTO THE LIVING ROOM.
【题目解析】：汉语句子的主干是：他站，然后示意我们进入客厅，翻译成英文时：He stood and gestured us to go into the living room.然后把句子的修饰成分:“在我们面前”，“片刻”，“然后”加上: in front of, for a moment, then。重点单词和词组：示意某人做某事：gesture sb to do sth. 客厅：living room
