专题06 科技发明创造（三）20篇 一、阅读单选 （2023上·福建福州·九年级统考期中）Nowadays the pollution of the sea is becoming an increasingly serious problem. How can we reduce the pollution in the sea and make the underwater environment better? Scientists in Norway have invented an underwater robot, which can help a lot. The robot is 45 kg in weight and uses special cameras to get 3D pictures. It can discover different kinds of pollution at the bottom of the sea. It will help clean-up teams find the areas, where there is rubbish and then they can spend most of their time and money removing the most harmful materials. The researchers (研究员) put their work to the test in a bay (海湾) in the city of Bergen. First, the robot swam up and down two meters above the seabed, collecting information. Then a computer turned the information into a map, which showed different rubbish materials in different colors. Thousands of objects were discovered in the bay, including bottles, metals, plastics, etc. “Bergen is a place where different industries come together, and the city is quite old, so there’s a huge amount of rubbish,” said Trygve Olav Fossum, one of the researchers. “We think the rubbish in the bay weighs 150 tons to 300 tons.” It is not always possible to remove everything. Some things are more harmful so it’s more important to clear them from the sea. “Glass isn’t really polluting the sea,” said Fossum. “So if you know there’s an area with a lot of glass, you don’t need to worry much about that and you can pay more attention to the things that are putting heavy metals into the environment.” The maps will be used to help the clean-up teams locate (定位) the most harmful materials so that they can remove them first. Thanks to the development of the science and technology, the underwater environment can be improved a lot. As well as helping to deal with pollution, the robot can also show where creatures like starfish are on the seabed. 1．How does the writer start the passage? A．Listing plans. B．Showing s
