(初中必刷题)沪教版七年级下册Unit 5 Water is life 单元限时检测
素材话题:AI发展与水资源短缺的关系
Artificial intelligence(AI) can now do amazing things.ChatGPT is an AI tool that can answer questions, tell stories, and do much more.But it's very "thirsty", said a new study.
When ChatGPT works, its"home"—data(数据) centres around the world—gets very hot.Workers then have to use water to cool them down.Cold water goes into pipes near the computers at these centres.Because the computers are very hot, the water turns into vapour(水蒸气) and goes into the air.The water needs to be super clean.If they use seawater, it can eat away the pipes.
If you ask ChatGPT 20 to 50 questions, it needs to"drink" a 500-millilitre bottle of water.When people trained ChatGPT, it used 700,000 litres of water, said the study.This is the amount that is needed to make about 370 cars.
ChatGPT is not the only one that needs data centres.Everything you do with computers needs data centres to work.There are more than 8,000 data centres in the world.The number is still growing.If AI keeps using a lot of water, we may have to "fight" with AI for water.
AI uses a lot of water to"grow".Many people may not have enough water to drink because of water shortage.However, we need better AI to have a better future.Should we rethink the use of AI?
a.By comparing one thing with another.
b.By thinking of a thing as a person.
c.By drawing a conclusion(得出结论) from the different points.
d.By giving numbers to make the point clear.
