题目

答案：【考点】平面镜成像的相关作图． 【分析】由光的反射定律：反射光线、入射光线、法线在同一个平面内，反射光线与入射光线分居法线两侧，反射角等于入射角，可知：法线是反射光线与入射光线形成夹角的角平分线，而平面镜与法线垂直而且过反射点，从而确定平面镜的位置． 【解答】解：过入连词成句。1. evening , his, often ,homework ,does ,in ,Tom ,the     ___________________________________________________________.2. great, Your, sound, friends, new    ___________________________________________________________.3. is, Which, favourite, your, festival    ___________________________________________________________?4. are, table, the, There, five, milk, on, cartons, of     ___________________________________________________________.5. a, day, times, Eddie, to, his, bowl, many, walks    ___________________________________________________________.
