单项选择题
California seems to be the home of the homeless since many are often observed tramping along railroad tracks and through the downtown areas of the cities.
A．roaming
B．trimming
C．stealing
D．stamping
答案
参考答案：A
解析： 本题中，tramping的意思是“流浪”。A项“roaming闲逛”符合题意，如：The visitors roamed around the town.(这些来访者在城里游逛。)其他三项“trimming整理；stealing偷盗；stamping冲压”都不正确。
