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

【正确答案】 A

【答案解析】解析：tramping意为“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。
