B解析分析：by phone(用打电话的方式)(延伸)1)by+不带冠词或物主代词的单数名词表示“交通方式”或“传媒联系方式”，如：by bus，by train，by car，by bike，by plane，by air(＝by plane)，by ship，by sea/by phone，by airmail，by ordinary mail，by fast mail，by radio(用无线电联系方式)2)注意on foot(步行)，介词不是by 3)He went there by bus．＝He went there on a bus．＝He took a bus to go there．
