把萨拉托加大捷作为北美独立战争的转折点，主要是因为在这场战役之后：（ ）
①大陆军扭转了在战场上的劣势 ②美国赢得了法国、荷兰、西班牙等国的援助
③英国完全陷于孤立 ④美国独立战争赢得世界人民广泛同情和支持
A．①②③④
B．①②
C．②③④
D．①③④
答案：B
题目分析：英国也没有完全陷于孤立，③的表述不准确；④中“世界人民广泛同情和支持”不符合历史事实，在萨拉托加战役后，只有欧洲的某些国家参加了美国对英国的作战，并不是“广泛”。因此③④错误，排除ACD项。萨拉托加大捷是转折点，扭转了战场上的不利局面，同时美国获得了西方国家的支持。故选B。
点评：萨拉托加大捷是世界史上著名的战役，是北美英属殖民地十三州独立战争的转折点。该战役加速了北美人民的独立进程。经过北美人民的艰苦抗争，终于在1783年迫使英国承认美国独立。独立战争结束了英国的殖民统治，实现了国家的独立，确立了比较民主的资产阶级民主体制，有利于资本主义的发展，对拉丁美洲和法国大革命起到了推动作用。
