Question

    Here is a story of the Baiji River Dolphin. It makes its home in the Changjiang River. Over 20 million years ago,the Baiji River Dolphin left the sea,swam up the Changjiang River and has lived there ever since. It has smaller eyes than other kindvS of dolphins because the Changjiang River has many small pieces of earth in it. The small size helps to protect its eyes. However,because it has such small eyes,it can not use its eyes to find food. Instead,this kind of dolphin uses sound waves (聲波) to find food. This makes it so unusual.

   About 2,200 years ago,there were thousands of dolphins in the Changjiang River,but today,not many people can see the dolphins. Their population has dropped to 150. Scientists say that the dolphin population has gone down because the population of people on the Chnagjiang River has gone up. They also say that the new dam (大項(xiàng)) on the river is also making the dolphin die because it doesn’t have food to eat.
