A．completed B．complete C．had been completed D．have been completed 【答案】D 【详解】考查谓语动词时态和语态。句意：任务的所有准备工作已经完成，我们准备开始了。根据“and we’re ready to start.”可知，现在准备出发，说明“任务的所有准备工作已经完成”，强调动作已完成且结果与现在相关，应用现在完成时，且preparations和complete之间是被动关系关系，需用现在完成时被动语态（have been completed）。故选D。 10．All the invitations for the party ________ already.‌ A．have sent B．have been sent C．had sent D．were being sent 【答案】B 【详解】考查现在完成时的被动语态。句意：派对的所有邀请函都已经被发出了。句中的already是现在完成时的标志词，表示动作已经完成。主语All the invitations是send这个动作的承受者，因此需要用被动语态。现在完成时的被动语态结构为“have/has + been + 动词过去分词”，主语是复数，助动词用have，所以正确形式是“have been sent”。故选B。 11．The area is always ________ with war.

A．has left B．have left C．is leaving D．left 【答案】C 【详解】考查动词时态和主谓一致。句意：一位专家和几名助手下周将前往南京协助这项工作。根据时间状语“next week”可知，句子表达将来的事情，应该用一般将来时，leave可以用现在进行时表将来，主语expert是单数，be动词用is。故选C。 13．Professor Smith, along with his assistants, ________ on the project day and night to meet the deadline.

A．sleeps; turn on B．is; turn up C．sleeping; turn down D．is sleeping; turn off 【答案】D 【详解】考查时态及动词短语。句意：琳达，你爸爸正在睡觉，去把电视关掉。turn on打开；turn up出现；turn down关小、调低；turn off关掉。根据“now”可知，此处表示现在正在做的事，应用现在进行时，结构是：be +现在分词。结合选项可知，此处表示爸爸正在睡觉，把电视关掉。故选D。 15．The boy ________ a picture now. A．draws B．is drawing C．will draw D．are drawing 【答案】B 【详解】考查时态和主谓一致。句意：这个男孩正在画画。根据时间状语“now”可知，句子时态应用现在进行时be+doing，主语“The boy”是单数形式，因此be动词应用is。故选B。 16．—Music and Art enter the Entrance Examination for the high school, is it true? —Yes.

A．which produce B．which are produced C．that produce D．which are producing 【答案】B 【详解】考查定语从句和被动语态。句意：江苏省生产的车非常畅销。分析句子结构及选项可知，空处为限定性定语从句修饰先行词“The cars”，关系词作主语，先行词与从句动词produce是被动关系，需用被动语态（be done），只有B选项表达正确。故选B。 18．When and where to build the shopping mall ________ not been decided.

A．gave B．was given C．was giving D．had given 【答案】B 【详解】考查动词的时态和语态。句意：我有十分钟的时间来决定是否应该拒绝这个提议。分析句子结构可知，主语“I”和动词“give”之间是被动关系，即 “我被给予十分钟”，故用被动语态，其结构为：be + 动词的过去分词。故选B。 21．His parent died when he was young, so he was ________ by his aunt. A．brought out B．grown up C．brought up D．grown 【答案】C 【详解】考查动词短语。句意：他的父母在他小的时候就死了，因此他是由他的姑姑抚养长大的。A. brought out出版；生产；使显现；B. grown up长大成人，不及物动词短语；C. brought up养育；抚养，及物动词短语；D. grown生长；变得。根据“His parent died when he was young”可知，此处表达“由他的姑姑抚养长大”符合语境。故选C。 22．The little girl ________ by her mother when she fell off the bike.

He and his friends were walking through the rainforest when they came across a man cutting down a huge tree. This kind of illegal activity is a big problem in rainforest around the world. It causes climate change and destroys the natural living environments of animals and plants. White reported this to forest guards, but the tree cutter had run away from the scene already when the guards arrived. This experience made him worried. White, a trained engineer, thought technology could be part of the solution in the fight against illegal tree cutting. “The rainforest is a noisy place, but it’s also a noisy thing to cut a tree down. “He later told a newspaper reporter. “It struck me that there had to be way to hear this. “Over the next few months, White created a piece of warning equipment called “Guardian”. Fixed on treetops, Guardians can pick up the sound of cutting trees, it sends an alarm to forest guards, indicating where the sound is coming from. The guards then set off to stop the illegal activity.  “If you respond in time, there’s a chance that you can stop much of the tree cutting,” White said. White set the first guardians in a wildlife protection area in Indonesia. They worked well. After that, he started a non-profit group called Rainforest Connection to set Guardians all over the world. 26．According to Paragraph 1, illegal cutting of forest trees leads to _________.

(它会向森林守卫发出警报，表明声音来自哪里。随后，守卫者出发去阻止这一非法活动。)”可知，报警装置可以帮助守卫者快速辨别声音来源，抓住砍伐树木者。故选C。 29．推理判断题。依据第二段中的“Fixed on treetops, Guardians can pick up the sound of cutting trees, it sends an alarm to forest guards, indicating where the sound is coming from. (固定在树梢上，守卫者可以听到砍树的声音，它会向守卫者发出警报，指示声音的来源。)”可推测出，报警装置的作用通过跟踪声音找到砍树的地点。故选A。 30．推理判断题。本文核心内容是介绍Topher White为阻止非法伐木发明的保护森林的装置Guardian，写作目的是介绍这项用于森林保护的发明。故选D。 B In the 13th century, the famous Italian traveller, Marco Polo, travelled a long way to China. During his stay in China, he saw many wonderful things. One of the things he discovered was that the Chinese used paper money. In western countries, people did not use paper money until the 15th century. However, people in China began to use paper money in the 7th century. A Chinese man called Cai Lun improved the way of making paper almost 2,000 years ago. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book. Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are wasting nearly 48,000 trees every day. Since it takes more than 10 years for a tree to grow, we must start using less paper now. If we don’t, we will not have enough time to grow more trees to take the place of those we use for paper. So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can choose drinks in bottles instead of those in paper packets. We can also use cotton handkerchiefs (手帕) and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant gives us a paper bag, we can save it and reuse it later. Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late. 31．When he was in China, Marco Polo __________. A．discovered Cai Lun invented paper B．learned to make paper C．saw many wonderful things D．read a lot of books 32．People in western countries first used paper money in the __________ century. A．17th B．15th C．13th D．7th 33．About __________ tons of paper is thrown away every day in our city. A．1,700 B．2,000 C．2,800 D．48,000 34．Which of the following is NOT the way of saving paper? A．To use both sides of every piece of paper. B．To use the paper bags from shops more than once. C．To use cotton handkerchiefs instead of paper ones. D．To grow more trees. 35．Which is the best title of the passage? A．Saving Paper B．The History of Paper C．Cotton Handkerchiefs Back Again D．Cai Lun, the Great Inventor 【答案】31．C 32．B 33．C 34．D 35．A 【导语】这是一篇夹叙夹议的文章。文章主要讲述了节约用纸的重要性以及如何节约用纸。 31．细节理解题。根据第一段中“During his stay in China, he saw many wonderful things. (在中国逗留期间，他看到了许多奇妙的东西。)”可知，当马可·波罗在中国的时候，他看到了许多奇妙的东西。故选C。 32．细节理解题。根据第一段中“In western countries, people did not use paper money until the 15th century. (在西方国家，人们直到15世纪才开始使用纸币。)”可知，西方国家的人们在15世纪首次使用纸币。故选B。 33．细节理解题。根据第二段中“Every day, people throw away about 2,800 tons of paper in our city. (每天，在我们的城市人们扔掉大约2800吨纸。)”可知，在我们城市,每天大约有2800吨纸被扔掉。故选C。 34．细节理解题。根据第三段中“We can use both sides of every piece of paper (我们可以使用每一张纸的两面)”“We can also use cotton handkerchiefs (手帕) and not paper ones. (我们也可以用棉手帕而不是纸巾。)”“If the shop assistant gives us a paper bag, we can save it and reuse it later. (如果店员给我们一个纸袋，我们可以把它保存起来，以后再使用。)”可知，节约用纸的方式有很多种，但不包括种更多的树。故选D。 35．主旨大意题。通读全文，尤其是最后一段点明了文章的主旨是节约用纸。故选A。 学科网（北京）股份有限公司 ( 1 )原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 $ 编写说明：本套试卷紧扣《英语 基础模块1》（外研版第二版）教材，以教材单元为基准精准覆盖核心考点。 每个单元设置AB卷，A卷为基础巩固卷，侧重基础考点训练，帮助学生扎实掌握知识要点；B卷为能力提升卷，注重知识整合与全面检测，引导学生构建知识网络。模拟实战情境，聚焦解题能力突破，全面提升应试能力与知识应用水平。 《英语 基础模块1》（外研版第二版）《单元过关卷》 Unit 5 We Have Only One Earth!
