The Lion's Share
After a hunt, lions always take the largest amount of food for themselves- and few animals dare dispute their rightto it. That's why we have the lion's share, which means the largest part or the greatest amount.
狮子与群兽合力狩猎, 但以大欺小, 分给自己的几乎是全部的猎物. 由此, "the lion's share" 就指最大的部分或最多的份量.
