Ⅱ　阅读理解
The gentle giants of our oceans are whale sharks. It's the biggest whale shark and can reach as long as 41.5 feet, and these amazing creatures are not only the biggest sharks, but they are also biggest fish of any kind.

Whale sharks have a lifespan of 70 years on average, and they spend their days gently swimming in the warm and tropical oceans.
Their teeth are the size of match heads, and while their jaws could be powerful, they have never tended to attack humans. Their teeth play no role in eating, as plankton (浮游生物) does not need to be chewed. They are to be found in numbers in the warmer oceans and they prefer the deep waters of open oceans. They tend to travel alone.
Several times a year they gather together in certain spots where plankton is plentiful. Those areas are all within a 30°north or south latitude from the equator. Sadly whale sharks are targeted by commercial fisheries at those spots.
How easy it must be for the fishermen to catch those beautiful creatures who can only swim at 3.5 miles per hour! So great a loss in numbers have they suffered that whale sharks are now listed as one of the endangered species. Some countries have started to take measures to protect the whale sharks from extinction.
The Philippines, India and Taiwan have all banned the fishing, selling, importing and exporting of whale sharks for commercial purposes. However, the law doesn't seem to be effective because the hunting and killing still goes on today, especially in Taiwan and the Philippines. Each whale shark can fetch around $21,000. In parts of Asia they are known as the “money shark”．
The mighty dollar wins again at great cost to our habitat, and we will not know what we have lost until we have lost it forever. Therefore, it is high time for us to do something for the whale sharks.
