But it took forever to find a bike! 用法：此句使用 “it takes (sb.) some time to do sth” 句型，其中 “it” 是形式主语，真正的主语是后面的 “to find a bike”；“forever” 此处并非 “永远”，而是夸张地表示 “很长时间”，强调寻找过程的漫长。例：It took forever to wait for the bus in the rain.（在雨中等公交车等了好久。） 2.

The app even let me check my daily progress. 用法：“let sb. do sth” 是使役动词结构，后接不带 “to” 的不定式 “check”；“daily progress” 表示 “每日进展”，“progress” 是不可数名词，不能加 “s”；“even” 加强语气，表 “甚至”，突出 app 功能的全面性。例：The coach lets us track our progress every week.（教练让我们每周记录自己的进步。） 7. What’s Timmy’s attitude to his mum trying to take his phone away? 用法：“What’s one’s attitude to...?” 是询问 “某人对…… 的态度” 的常用句型；“trying to take his phone away” 是现在分词短语作后置定语，修饰 “his mum”，说明 “妈妈” 的行为。例：What’s your attitude to students using phones in class?（你对学生在课堂上用手机持什么态度？） 8.

What will C. Why would D. When may 一、“except” 与 “except for” 辨析 1. 核心区别：“except” 用于同类排除，如 “We work every day except Sunday.（除周日外每天工作）”；“except for” 用于不同类修正，如 “The room is clean except for a few books.（房间干净，除了几本书）”。 2. 记忆技巧：同类排除用 “except”，整体好细节差用 “except for”，结合场景造句对比即可掌握。 二、“cost”“spend”“take” 用法区分 1. 主语差异：“cost” 主语是物，如 “The book cost 20 yuan.（书花 20 元）”；“spend” 主语是人，如 “I spent 20 yuan on the book.（我花 20 元买书）”；“take” 用 it 作形式主语，如 “It took me an hour to read it.（读它花我 1 小时）”。 2. 句式口诀：物用 cost，人用 spend，it 用 take，结合例句反复练习即可区分。 三、动词不定式作宾语补足语 1. 带 to 与不带 to：多数动词接 “to do”，如 “ask sb. to do（要求某人做）”；使役动词（let/make 等）接不带 to 的不定式，如 “Let me help you.（让我帮你）”，被动语态需还原 to，如 “He was made to wait.（他被迫等待）”。 2. 实例积累：记牢 “ask, tell, let, make” 等词的用法，多造句子巩固。 四、“anywhere” 与 “somewhere” 用法 1. 场景差异：“anywhere” 用于否定句和疑问句，如 “I can’t find it anywhere.（我到处找不到）”；“somewhere” 用于肯定句，如 “It must be somewhere.（它一定在某处）”。 2. 转换练习：将肯定句改为否定句时，把 “somewhere” 换成 “anywhere”，如 “I saw him somewhere.”→“I didn’t see him anywhere.”。 一、完形填空 （2025八年级·全国·专题练习）Vegetables and meat used to be eaten up within one day.

This smart program can solve math problems, write code, and answer questions like top models such as Open AI’s GPT-40, but it costs much less to build. The team spent only $5.58 million (1/70 of Open AI’s cost) and used 2,048 computer chips (芯片) for two months. This shows that good ideas can beat big money. DeepSeek-R1 learns by trying many times and getting better, like how students practice maths. Other Als need lots of prepared examples, but R1 improves by itself. For example, in a global math test, it got 79.8% right, a litter higher than Open AI’s model. A simple version of R1 can even run on low-cost computers, helping schools and small companies. DeepSeek-R1 is free to use and change. On its first day online, over 19,000 programmers all over the world started projects to study it. A German scientist said experiments (实验) with RI cost $10 instead of $300 with other Als. Even Meta (a famous U. S. tech company) top scientist said, “This kind of free AI could change the world.” US tech companies are worried. Meta plans to spend $65 billion more on AI research. Experts say China is catching up fast. A report in Nature magazine called R1 a “big step forward”, proving (证明) that smart ideas beat expensive tools. As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China shows the world that great things come from new ideas and hard work, not just money. 1. According to paragraph 1, DeepSeek-R1 is able to ______. ①write code  ②work out math problems  ③do experiments  ④answer questions A．①②③ B．①③④ C．②③④ D．①②④ 2. It cost about ______ to build Open AI. A．$5.58 million B．$65 billion C．$390 million D．$300 3. The underlined words “it” in paragraph 2 refers to ______. A．GPT-40 B．Open AI C．Meta D．R1 4. The engineer says, “We want AI to be a friend, not something only rich people can use” to ______. A．explain why RI is free B．compare R1 with Meta's AI C．encourage students to study math D．show that expensive AI models are useless 5. The main purpose of the passage is to ______. A．explain how computer chips work B．introduce a low-cost AI model from China C．encourage students to become programmers D．compare Chinese and American AI technologies 三、选词填空 （24-25八年级上·广东潮州·阶段练习）请从方框内选择适当的词并用其正确形式填空，使文章完整连贯。注意每空一词，每词仅用一次，有两词为多余项。请将答案写在答题卷对应题目的答题卷位置上。 about,   heavy,  however,  only,  woman,  easy,  water,  child,  chore,  carry,  take,  although All over the world, families wash, cook, and clean their homes.

But it took forever to find a bike! 用法：此句使用 “it takes (sb.) some time to do sth” 句型，其中 “it” 是形式主语，真正的主语是后面的 “to find a bike”；“forever” 此处并非 “永远”，而是夸张地表示 “很长时间”，强调寻找过程的漫长。例：It took forever to wait for the bus in the rain.（在雨中等公交车等了好久。） 2. As I always make digital payments in China, I never carry my wallet. 用法：“as” 在此处作连词，引导原因状语从句，意为 “因为，由于”，说明 “never carry my wallet（从不带钱包）” 的原因；“make digital payments” 是 “进行数字支付” 的固定表达。例：As he knows the city well, he offered to be our guide.（因为他熟悉这座城市，所以主动提出当我们的向导。） 3. Except for today, I’ve had a great holiday. 用法：“except for” 引出与整体情况不同的细节（“today”），表示 “除了今天之外，假期整体很愉快”，隐含 “今天可能不太愉快” 的意味；主句使用现在完成时 “have had”，强调假期到目前为止的感受。例：Except for the last chapter, the book is easy to understand.（除了最后一章，这本书很容易理解。） 4.

This smart program can solve math problems, write code, and answer questions like top models such as Open AI’s GPT-40, but it costs much less to build. The team spent only $5.58 million (1/70 of Open AI’s cost) and used 2,048 computer chips (芯片) for two months. This shows that good ideas can beat big money. DeepSeek-R1 learns by trying many times and getting better, like how students practice maths. Other Als need lots of prepared examples, but R1 improves by itself. For example, in a global math test, it got 79.8% right, a litter higher than Open AI’s model. A simple version of R1 can even run on low-cost computers, helping schools and small companies. DeepSeek-R1 is free to use and change. On its first day online, over 19,000 programmers all over the world started projects to study it. A German scientist said experiments (实验) with RI cost $10 instead of $300 with other Als. Even Meta (a famous U. S. tech company) top scientist said, “This kind of free AI could change the world.” US tech companies are worried. Meta plans to spend $65 billion more on AI research. Experts say China is catching up fast. A report in Nature magazine called R1 a “big step forward”, proving (证明) that smart ideas beat expensive tools. As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China shows the world that great things come from new ideas and hard work, not just money. 1. According to paragraph 1, DeepSeek-R1 is able to ______. ①write code  ②work out math problems  ③do experiments  ④answer questions A．①②③ B．①③④ C．②③④ D．①②④ 2. It cost about ______ to build Open AI. A．$5.58 million B．$65 billion C．$390 million D．$300 3. The underlined words “it” in paragraph 2 refers to ______. A．GPT-40 B．Open AI C．Meta D．R1 4. The engineer says, “We want AI to be a friend, not something only rich people can use” to ______. A．explain why RI is free B．compare R1 with Meta's AI C．encourage students to study math D．show that expensive AI models are useless 5. The main purpose of the passage is to ______. A．explain how computer chips work B．introduce a low-cost AI model from China C．encourage students to become programmers D．compare Chinese and American AI technologies 【答案】1. D 2. C 3. D 4. A 5. B 【导语】本文通过对比和举例，介绍了深度探索R1这一低成本、高性能的人工智能模型，并强调了其在全球人工智能领域的重要性和创新意义。 1. 细节理解题。根据“This smart program can solve math problems, write code, and answer questions”可知DeepSeek-R1能解答数学题，写代码，回答问题，故选D。 2. 细节理解题。根据“The team spent only $5.58 million (1/70 of Open AI's cost) and used 2,048 computer chips (芯片) for two months.”可知Open AI的建立大约花费是$5.58,000,000的70倍，即大约三亿九千万美元，故选C。 3. 词义猜测题。根据“Other Als need lots of prepared examples, but R1 improves by itself. For example, in a global math test, it got 79.8% right, a litter higher than Open AI’s model.”可知it指代R1，故选D。 4. 推理判断题。根据“DeepSeek-R1 is free to use and change.”及“We want AI to be a friend, not something only rich people can use”可知工程师说这句话的是为了解释为什么R1是免费的，故选A。 5. 主旨大意题。根据本文主要介绍了深度探索R1这一低成本、高性能的人工智能模型，并强调了其在全球人工智能领域的重要性和创新意义，所以文章的主要目的是为了介绍中国这一低成本的人工智能模型，故选B。 三、选词填空 （24-25八年级上·广东潮州·阶段练习）请从方框内选择适当的词并用其正确形式填空，使文章完整连贯。注意每空一词，每词仅用一次，有两词为多余项。请将答案写在答题卷对应题目的答题卷位置上。 about,   heavy,  however,  only,  woman,  easy,  water,  child,  chore,  carry,  take,  although All over the world, families wash, cook, and clean their homes.

They don’t even think...it!”和“...in many small villages in Africa, far away from the big cities, the houses don’t have water.”可知，此处与上文是转折关系，副词however“然而”符合语境，句首首字母大写。故填However。 3. 句意：在那些村庄里，为家庭取水通常是妇女的工作。根据下文“Children help their mothers and older sisters with this important...”可推知，为家庭取水通常是妇女的工作。此处表示泛指，应用woman“妇女”的复数形式women，空后的job是名词，所以空处应填women的所有格形式women’s，修饰名词。故填women’s。 4. 句意：孩子们帮助他们的母亲和姐姐完成这项重要的家务。根据上文“it is usually...job to get water for the family home”可推知，此处指的是取水这个重要的家务，名词chore“家务”符合语境，this后接可数名词的单数形式。故填chore。 5. 句意：但往往湖泊或河流离家很远，水很重，所以妇女和儿童无法一次就获得足够的水。空处缺少形容词作表语，修饰water，结合所给单词可知，形容词heavy“重的”符合语境。故填heavy。 6. 句意：通常需要很多个小时和不止一个人去取水。根据“It usually...many hours and more than one person to get water.”可知，需要花费很多个小时去取水，结合所给单词可知，动词take符合语境，根据usually可知，时态是一般现在时，主语It表示单数，所以空处应填take的第三人称单数形式takes。故填takes。 7. 句意：这就是为什么孩子们有时不能上学。根据“sometimes don’t go to school”可知，此处指孩子们有时无法上学，此处表示泛指，所以空处应填child“孩子”的复数形式children。故填children。 8. 句意：Q桶可以装大约50升水，而且很容易拉动。根据“The Q Drum can...about 50 liters (升) of water”可知，Q桶可以装大约50升水，动词carry“运输”符合语境，can后接动词原形。故填carry。 9. 句意：这意味着妇女或儿童只需一次就能取到足够的水。根据所给单词和“That means a woman or a child can make...one trip to get enough water.”可知，此处指只需一次就能取到足够的水，only“唯一的”符合语境。故填only。 10. 句意：这对那些村庄的家庭来说生活变得容易多了。根据“This makes life much...for the families in those villages.”和所给单词可知，Q桶这项发明使得生活变得容易多了，空处应选形容词easy“容易的”，much常用于修饰形容词比较级，所以空处应填easy的比较级easier。故填easier。 16 / 16 学科网（北京）股份有限公司 $$
