据英国《镜报》6月22日报道,47岁的戈弗雷·巴古马(Godfrey Baguma)被称为乌干达
最丑男子,现在他已经第八次当父亲。
巴古马患有罕见怪病,因此其容貌十分奇特。他被称为Sebabi,意为“最丑的乌干

已经生了6个孩子。而巴古马数年前破裂的第一次婚姻还为其留下2个孩子。
巴古马接受采访时称,前妻之所以和他结婚是因为他有钱,而第二任妻子怀孕6个
月后曾离开他,不过最终选择留下。2013年他们在巴古马的家乡卢恩戈区(Lwengo)的
Kyazanga举行了婚礼。观礼宾客需花费4000乌干达先令(约合人民币7.6元)参加招待会。
据悉,巴古马曾是一名鞋匠,他现在利用自己独特的容貌谋生。巴古马作为最丑乌

亮点:2012年至2013年10月期间,在美国的中国留学生购买了总价值约155亿美元的新
车和二手车。相对应的美国学生群体购买的汽车总价值为47亿美元。
大约三年前,美国艾奥瓦大学的中国留学生开始到艾奥瓦城的Carousel Motors汽车销
售店,给自己的奔驰和奥迪豪华车做保养。后来,总经理帕特·林德(Pat Lind)问,他
们最初买车的时候是否考虑过到他店里来买。学生们说没有。在中国还没来上学以前,
就有人告诉他们,要到芝加哥买车。
因此,林德开始赞助这所大学的中国留学生联合会的活动,该组织在留学生来美之前就
为他们提供各种信息。此后,中国学生的汽车购买量增加了一倍,现在已经占到这家经
销商汽车总销量的5%左右。这家店的位置距校园约有3公里。“我们开始做广告。”林
