（2）35 南北温差大，气温由南向北逐渐降低
（3）5 全国普遍高温
（4）43 13
【解析】
试题分析：本题考查我国气温分布规律。（1）从两幅气温曲线图可以看出，甲图气温年较差较大，应为我国位置较北的城市哈尔滨，乙图气温年较差较小，应为我国位置较南的城市广州。（2）从两幅气温曲线图可以看出，甲图1月气温约为-20℃，乙图1月气温约15℃，则两地一月平均气温大约相差35℃，这说明我国冬季气温南北差异大。 （3）从两幅气温曲线图可以看出，甲图7月气温约为23℃，乙图7月气温约28℃，则两地七月平均气温大约相差5℃，这说明我国夏季南北普遍高温，温差小。（4）A图中最高气温为23℃，最低气温为-20℃，故其南北温差为43℃，B图中最高气温为28℃，最低气温为15℃，故其南北温差为13℃。
