Question

【题目】My mother walked into the bedroom q________ while my sister was sleeping because she was afraid to wake her up.

Answer 1

【答案】quietly

【解析】

句意：我妈妈在我妹妹睡觉的时候悄悄地走进卧室，因为她（妈妈）害怕吵醒她（妹妹）。

句中walked是动词，所以此处使用副词对其进行修饰；根据句中“because she was afraid to wake her up”可知，妈妈害怕吵醒妹妹，所以她悄悄地走进卧室；quietly是副词，意为“安静地，悄悄地”。故填quietly。
