名词解释：所谓鱼翅(shark fin)，就是鲨鱼鳍中的细丝状软骨，是用鲨鱼的鳍加工而成的一种海产珍品。你知道怎么用英语表达吗?

For more than a decade, shark fin soup has been served in any meal intending to highlight the host's wealth, resulting in the consumption of hundreds of millions of shark fins.

Up to 73 million sharks are killed each year for their fins.

One third of the world's nearly 500 shark species are facing extinction.

However, the shark fin market has been hit by a drastic market downturn recently. Precise figures are difficult to come by, but industry estimates the market has shrunk by between 50 and 70 percent.

十多年以来，鱼翅汤流行于以展现主人财富为目的的任何一餐之中，而这导致了亿万件鱼翅的消耗。

为了获得鱼翅，人类每年会杀掉7300万条鲨鱼。

在全世界将近500个鲨鱼品种中，有三分之一正濒临灭绝。

然而，最近鱼翅生意遭受了市场衰退的沉重打击。虽然很难获得精确的数据，但据行业内分析，市场萎缩了50%至70%。

【讲解】

文中的“shark fin”是鲨鱼翅的意思，即为人们常说的“鱼翅”，其中fin意为“鳍，鱼翅”，人类割掉鱼鳍之后将鲨鱼扔回海里，鲨鱼会因为溺水或者流血过多而死。

另外，文中face extinction意为“濒临灭绝”，其中extinction意为“消亡，绝种”，如mass extinction(大量消亡)，in danger of extinction(面临灭绝的危险)。

小编在此呼吁——保护鲨鱼，请拒绝鱼翅!
