深高北初一英语备课组 班级: 姓名： 7B U5 限时训练 I. 完型（每空1分，共10分） An old saying goes, “When in Rome, do as the Romans do.” I learned the meaning of this when I studied in Russia. One day I _1_ some of my Chinese friends to a famous local restaurant in Moscow. My guests and I were excited about visiting Red Square and happy about our meeting. We chatted _2_ until the waiter told me that we were talking too loud. We turned our voices lower. But this didn’t last long. The waiter came over to us two more times with the same _3_. How bad an impression we must have left on the local people! In China, it’s natural and _4_ for a host to make a lively atmosphere (气氛). However, in Russia and western countries, having a meal in a public place means you must _5_ your voice low. You need to be polite to others. I felt _6_ about this. Even though we tried our best, it’s very difficult to form a new habit. Russians have their own special habits. My Russian friend, Andrey, always looks around and thinks for a while before leaving home. I asked him _7_ he did this. “Aha,” Andrey said. “In Russia, people always spend about a minute _8_ things and plans in their minds before leaving. So they will leave _9_ necessary behind.” Finding the differences between _10_ is very interesting. I’d like to keep my eyes and mind open. 1. A. made B. invited C. told D. taught 2.

But these little things can do a more important job: testing the cleanness of people’s drinking water! The main water station in Warsaw, Poland, provides water for millions of people there. All the water depends on eight clams, reported The Economist. Clams are very sensitive (敏感的) to water pollution. If the water is not clean enough, they shut their shells (壳). So, the water station “employed” the clams. They connected their shells to a computer system (系统). When four or more clams close their shells at the same time, an alarm will go off. To make sure the clams don’t get too used to the environment, they only work for three months.Then new clams will take over the job. The water station said that this works well to test water quality (质量). There’s a documentary film on this story, called Fat Kathy. The film shows the dependence of people on nature and the world around them, said Bored Panda, a leading art and pop culture magazine. There are some other human helpers. In Australia, people use dung beetles (蜣螂) to clean cow dung (粪便). Dung beetles can break the dung down into nutrients (营养物) that help plants grow. Cockroaches (蟑螂) are used to deal with kitchen waste. About 300 million cockroaches can eat 15 tons of food waste on a daily basis. And they themselves become good food for livestock (家畜).During the 2000 Summer Olympics in Sydney, Australia used more than a million earthworms (蚯蚓) to break down food and paper waste. 11. What do we know about the water station in Paragraph 2? A. It is the largest water station in the world.  B. It uses clams to test water quality.  C. It sells clams to millions of people.  D. It will build a home for clams.  12. What will clams do if the water is polluted? A. They will not drink any water. B. They will take off their shells.   C. They will close their shells. D. They will clean each other’s shells.  13. Why did the station connect clams’ shells to a computer system? A. To make the clams stay together.  B. To find where the clams are.  C. To check on their health.  D. To create an alarm.  14. How does the water station keep the clams from getting too used to the environment? A. By making them work for a short period of time.  B. By keeping them at other stations.  C. By changing the water quality at the station.  D. By making them do different kinds of jobs.  15. What do we know from the last paragraph? A. Good stories make good films.  B. People make the world wonderful.  C. Nature is important to people.  D. The environment is getting better.  B Do you know ChatGPT? It’s an artificial intelligence (AI, 人工智能 ) tool. It can answer questions, tell stories, and do much more. But it’s very “thirsty”, said a new study. ChatGPT has “homes” around the world in data centers (数据中心). When it works, the computers at the data centers get very hot. Workers then have to use water to cool them down. Cold water goes into pipes near the computers. The water needs to be very clean. They can’t use seawater because it can eat away at the pipes. When you ask ChatGPT 20 to 50 questions, it “drinks” 500 milliliters of water. Scientists used 700,000 liters of water to build ChatGPT. The water use is very big. People can make 370 cars with it. ChatGPT is just one AI tool. You need data centers to do everything on the internet. There are more than 8,000 data centers around the world. The number is still growing. We may have to “fight” with AI for water in the future. AI uses a lot of water to “grow”. The world’s water may not be enough. Many people don’t have enough water to drink. But AI technology helps people. Should we rethink how we use AI? Talk to your friends about it. 16. The new study used the word “thirsty” to show that _____.  A. ChatGPT looks like a man  B. ChatGPT can eat and drink  C. ChatGPT talks too much D. ChatGPT needs water when working 17. What do we know about the data centers in Paragraph 2? a. They are AIs just like ChatGPT. b.

What does the underlined word “them” in Paragraph 2 refer to (指的是)？  A. AIs like ChatGPT B. computers C. the workers D. the pipes 19. Why do the workers have to use clean water to do the cooling job? A. Because it is near the centers.  B. Because it is colder than seawater.  C. Because it is good for the pipes.  D. Because it is hard to get seawater.  20. Why does the writer write about cars in paragraph 3? A. To help readers know the big size of ChatGPT. B. To show the big water use in building ChatGPT.  C. To help scientists find a better way to build ChatGPT.  D. To give an idea about how to use ChatGPT.  第2节：阅读填空 Mother’s Day is on the second Sunday of May every year.
