We wanted to find a way to stop wasting 11 . At first, we looked at the piles left on the plates. “Class A must waste more,” someone said. But had we counted anything? We realized that we were only 12 . For five days, we helped the canteen workers 13 how many students ate lunch and how much food was left. Class A had eighty students and left four kilograms of food. Class B had forty students and left three kilograms. Class A’s pile was bigger, but the two groups were 14 in size. “If we only 15 the piles, we may be unfair,” said our teacher. We worked out the waste for each student. Class B actually wasted more per student. We began to look for 16 rather than blaming a class. Some students always asked for a large serving but could not 17 it. “Start with a little. You can always ask for more,” a canteen worker suggested. The next week, both classes wasted less. We were 18 , but our teacher reminded us that one week was not enough. Different dishes and different numbers of students could 19 the result. We decided to continue the study. Now we understand that numbers are helpful when we use them 20 . 注：serving 一份饭菜 11. A. time B. paper C. water D. food 12. A. singing B. guessing C. arguing D. forgetting 13.

Their school offered a silver certificate to any team that collected at least fifty books. On Saturday morning, the two friends brought four boxes to the library. Each box had “20” printed on it. Nina quickly wrote “80 books” on their poster. The librarian opened a box. “These numbers show how many books the boxes can hold,” she explained. “They don’t tell us how many are inside.” Nina looked into the boxes. Some were only half full. The friends put the books on a table and counted them carefully. There were fifteen in the first box, eighteen in the second, twelve in the third and sixteen in the last. The total was sixty-one. Nina stared at the poster. “Eighty sounds much better,” she said. “But they trusted us to count the books,” Sam replied. Nina crossed out eighty and wrote sixty-one. She also made a list of the books. “This helps us choose which books to send first,” the librarian said. She handed them their certificate. Nina felt relieved. They had collected enough books, and their record was now correct. For their next collection, Nina added a new heading to her notebook: “Counted, not guessed”. 注：certificate 证书 21. What caused Nina’s mistake at the beginning? A. She counted the same books twice. B. She forgot to count the last box. C. She treated all four boxes as full without checking. D. She thought the certificate required eighty books. 22. The underlined word “relieved” means ____. A. less worried B. more confused C. very impatient D. quite disappointed 23. What can we learn about Sam from his reply? A. He preferred quick work to careful work. B. He wanted a more expensive certificate. C. He thought counting books was unnecessary. D. He cared about giving a truthful record. 24. Which is the best title for the story? A. The Best Way to Pack Books B. A Smaller Number and a Better Record C. The Race for a Silver Prize D. A New Room for Old Books B A teacher writes 105 and 15 on the board. Then she covers the zero in 105. “Does this little circle matter?” she asks. The class soon sees that removing it changes the number completely. Zero can show an empty place in a number. In 105, there are no tens, but there is still a tens place between the hundreds and the ones. The zero keeps that place clear. It also works as a number itself: if you have three pencils and give all three away, you have zero left. Zero did not appear in its modern form all at once. People in ancient Babylon used signs to mark empty places. Later, people in India developed zero as a number. The Maya in the Americas also developed it independently. The full history is not clear enough to name one person as its inventor. Today, zero helps us write prices, dates and measurements clearly. A missing zero on a price tag can cause a serious misunderstanding. A symbol for “nothing” allows us to express many different amounts. It has a busy job for such a small circle. 25. Why does the writer begin with the teacher’s example? A. To show that the students dislike maths. B. To introduce a faster way of adding numbers. C. To help readers see that zero changes a number’s meaning. D. To explain why teachers often use circles. 26. Which conclusion is supported by Paragraph 3? A. Zero was invented by one well-known person. B. The Maya learned about zero from India. C. People accepted the modern zero at the same time. D. Different cultures contributed to the history of zero. 27. Which shows the structure of the passage? A. Example → Meaning → Development → Daily use B. Problem → Two opinions → Survey → Decision C. Invitation → Rules → Activities → Prices D. Time → Place → Characters → Ending 28. What type of text is the passage? A. A personal diary. B. A science explanation. C. A shopping notice. D. A travel story. C Look at these numbers: 1, 1, 2, 3, 5, 8, 13. Each number after the first two is the sum of the two before it. This is the Fibonacci sequence. People have found these numbers in some flower petals and in the spirals of some seed heads. However, a useful pattern is not a rule that every plant must follow. You may find a flower with five petals beside one with six. A petal may also be hidden or damaged, making a quick count unreliable. Eva’s science club counted twelve flowers from different plants in the school garden. Nine had five petals, and three had six. “Six is not a Fibonacci number,” one student said. “Shall we leave those three flowers out of our report?” Eva disagreed. The six-petal flowers were part of what they had found. Removing them would give readers an incomplete picture. The group took photographs, checked its counts and kept all twelve results. Their report said, “Most flowers in our small sample had five petals.” It did not say, “All flowers follow the Fibonacci sequence.” The club had found a pattern, but it still needed more observations before making a wider claim. 29. According to the rule in Paragraph 1, which number comes after 13? A. 15 B. 18 C. 20 D. 21 30. Why did Eva keep the three six-petal flowers in the report? A. They made the pattern easier to prove. B. They were part of the evidence the group collected. C. They were more beautiful than the other flowers. D. They showed that every plant followed the same rule. 31. Which statement is supported by the club’s observations? A. Most flowers in its sample had five petals. B. Every flower in the garden had five petals. C. Six-petal flowers were always damaged. D. Fibonacci numbers never appeared in plants. 32. Which would be the most useful next step for the club? A. Choose only flowers with five petals. B. Change six to five in its notebook. C. Count more flowers and record all the results. D. Ask classmates to vote for a favourite number. D Number Detectives Join us at the School Learning Centre this Saturday.

Asking “How many walk?” may look easy. But a useful survey needs a clear plan. 36 First, write one question that everyone can understand. 37 For example, “How do you usually get to school?” is easier to answer than “What do you think about transport?” Next, decide who will answer. If you ask only your closest friends, the result may be limited. 38 Try to include students from each class. Then record each person’s answer once. If Lily sometimes cycles and sometimes takes the bus, ask which she usually does. Put her in just one group. 39 Finally, choose a clear chart. Give it a title and label every group. 40 Also write down the date, so you can compare the results with a survey next term. A. Otherwise, one person may be counted twice. B. The following steps will help you collect numbers you can trust. C. Readers should be able to tell what the numbers stand for. D. They may travel in similar ways, so they cannot represent the whole school. E. A short, specific question is usually best. 作答栏 36____ 37____ 38____ 39____ 40____ 三 项目情境 读写综合 共两节，满分20分。阅读以下材料，完成学校英语社团开放日活动方案。 材料一 活动要求 The English Club is preparing an Open Day page for its booklet, Numbers in Daily Life.

The population doubled between 2005 and 2020, but stayed at 80,000 during the last five years. With more people living in the district, the local government should provide more buses.
