四、阅读短文，选择正确的答案。
When we talk about sharks, what do you think of them? A large body, a big mouth... Right? Do you know there’s a special shark? You can see it in some waters in the world. It’s WasteShark.
There is so much waste in the world, and a lot of it goes to the sea in the end. WasteShark deals with(处理) the waste. It is a drone(无人机) for cleaning up lakes, rivers, seas and so on.
The new drone can’t fly in the sky, but it can swim in the water. It works very hard, and it can work for eight to ten hours a day. Also, WasteShark is smart. Before going into the water, it uses a positioning system(定位系统) to find the waste and goes to “eat” it. It can test the water quality(水质), too.
WasteShark is a great invention. It is called “water cleaning robot”. It can reduce the waste and make the water clean. It can also protect the animals in the water. But it is hard to get to the big open sea and clean the waste there. People usually clean up the water near the beach. It is easy and cheap.
