VOA慢速英语2012.05.31 农场, 传统, produced, average, percent

Rebecca949

On average, organic farms produced twenty-five percent less compared to conventional farms. But yields of organic fruits and other perennial crops nearly equaled the yields from conventional ones. So did the yields of legumes such as soybeans. Legumes produce some of their own nitrogen fertilizer.平均而言，有机农场比传统农场产量低25%。但有机水果和其它多年生作物的产量几乎等同于传统产量。黄豆一类的豆科植物产量也是如此。豆科植物能够自己产生一些所需的氮肥。

However  organic vegetables and     crops like maize  and weet had a lot lower yields compared to conventionally   grand crops MR  says the soil on organic farm holds water better and that can reduce the yieds difference

The top of something is the highest part. So it is not surprising that top is part of another expression that describes an important person. 物体的顶部是最高的部分，所以top是另一个描述重要人物的短语的一部分，这并不奇怪。

The expression is top banana. A top banana is the leading person in a comedy show. The funniest comedian is called the top banana. The next is second banana. And so on.这个短语就是top banana。Top Banana是喜剧中的主角。最有趣的喜剧演员被称为top banana，接下来就是second banana。以此类推。
