下图为夏季奥运会和冬季奥运会前五名国家获得的奖牌数.选取并报告主要特点，总结信息，并进行相关比较。

The first bar chart shows which countries have won the most medals in the winter Olympics. It also states how many golds, silver and bronze medals each country has achieved. In contrast, the second graph shows which nations have won the most medals in the Summer Olympics.

Overall, the first graph shows that in the winter Olympics, Norway has gained the most medals, winning approximately an equal number of gold, silver and bronze medals. It has won about 370 medals, whereas Canada, in fifth place, has won approximately 200 medals.

The results of the summer Olympics are quite different, however, with the USA having won the most medals. Overall, the USA has won just over 2,500 medals, a much higher number than the other four countries on the graph. Russia is the second highest, winning approximately 1,800 medals.

To summarise, the bar charts illustrate how many medals the highest-ranking countries have won in the summer and winter Olympics. The results of each Olympics are very different, with the USA, Russia and Germany being successful in both.

第一张柱状图显示了哪些国家在冬奥会上获得了最多的奖牌。它还说明了每个国家取得了多少枚金牌、银牌和铜牌。相比之下，第二张图显示了哪些国家在夏季奥运会上获得的奖牌最多。

总的来说，第一张图显示，在冬奥会上，挪威获得的奖牌最多，获得的金银铜牌数量大致相等。它获得了大约370枚奖牌，而排在第五位的加拿大则获得了大约200枚奖牌。

然而，夏季奥运会的结果却截然不同，美国获得的奖牌最多。总的来说，美国获得的奖牌数仅有2500多枚，比图上的其他四个国家多得多。俄罗斯是第二高的国家，获得了大约1800枚奖牌。

综上所述，柱状图说明了排名最高的国家在夏季和冬季奥运会上获得了多少奖牌。每届奥运会的结果都大不相同，美国、俄罗斯和德国都取得了成功。
