这个题应当选rating，原题可译为：截至去年底，首相的支持率已经下降到仅有12%。虽然中文里“approval rating”通常被译为支持率，但是rating的含义更倾向于“等级，级别”，也就是说rating是指在跟其他事物的比较中鉴别出的这个事物的重要程度，受欢迎程度等等。比如ratings就是指电视电台节目的收视率ratio指“比率”，通常强调某个部分在一大个整体中所占的地位，一般是通过与其对立或者相关部分的比较而言，例如：The ratio of men to women in this department is very high.(这个部门中，男女比例很高）rate是使用最频繁的一个词，它可以指“速度”“率”例子：The can runs at an average rate of 100km per hour. (汽车以每小时100千米的平均速度行驶）（rate的这个意义就相当于speed)criminal rate/divorce rate/unemployment rate 犯罪率、离婚率、失业率（rate所指的“率”一般是就部分在整体中的地位而言，不涉及比较）我尽量写得很详细了，希望能帮到你
