Last year, I visited the main jumping-off point on the US-Mexican border: El Sasabe on the Sonora-Arizona border. In the month of May, before the summer's searing and deadly heat, local authorities estimated a daily average of 1,000 migrants attempting to cross.
去年，我参观了美墨边境上一个主要的边防点--索诺拉-阿里桑那（Sonora-Arizona）边境上的El Sasabe。当地政府估计在酷暑来临之前的五月份，这里平均每天有1000人试图偷越边境。今年我又参观了这个地方，试图偷越边境的人数估计已经增加到了每天1500至1800人。
