阅读下面的对话，从每题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项。
A school in Beijing is holding a "Lost and Found Week". A reporter is talking to a student at the school gate.
Reporter: Good morning! I hear you found some things in the library.
Student: Yes. Look at this pencil. It's yellow.
Reporter: ______
Student: Yes, it is. And the eraser is hers, too.
- A. Is this your pencil?
- B. Is this her pencil?
- C. What color is the pencil?
- D. Are these her pencils?
答案：B
解析：本题考查物主代词与 Is this…? 问归属句型的辨析。下文回答为 Yes, it is，说明问句应为 Is this…? 的一般疑问句，排除 C（特殊疑问句）和 D（复数 are these，而答语是 it is）。再看语境：学生说“我捡到了一些东西”，说明铅笔不是学生本人的，所以不能用 your（你的），而应根据下一句“the eraser is hers, too（橡皮也是她的）”推出铅笔属于一位女生，用 her。A 项 Is this your pencil? 与答语 Yes, it is 形式上匹配，但与“捡到的失物”语境和 hers 相矛盾，属于审题不清的典型陷阱。故选B。

阅读下面的短文，从每题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项。
Last Monday, Class 1 had a "Show and Tell" day. Every student brought one school thing to school and introduced it in English.
"Good morning, everyone!" said Li Hua. "This is my new ruler. It is white. These are my sister's books. They are green and white. Ms. Wang, our English teacher, is very kind. She ______ nice to all of us." All the students clapped their hands happily.
答案：B
解析：本题考查 be 动词与主语的搭配。句子主语是 She，属于第三人称单数，按照“我用 am，你用 are，is 连着他她它，复数全部都用 are”的规则，应选 is。易错点：① 受前一句 books（复数）影响误选 are，忽略了本句主语是 She；② 误选 am，am 只能与 I 搭配；③ 误选 be，be 是动词原形，不能单独作谓语，需要根据主语变形。故选B。

School News: The Lost and Found
Hello, everyone! I'm Lin Tao from Class 3, Grade 7. Today is Tuesday, October 12th. Our school has a Lost and Found activity in the school hall from 2:00 p.m. to 4:00 p.m. this afternoon.
Many students are there. Wang Lei finds a red pen. "Is this your pen?" he asks Li Mei. "No, it isn't mine. Mine is black," says Li Mei. Then Wang Lei asks, "Is it Zhang Hua's?" "No, it isn't his. His pen is at home," answers Li Mei.
At 3:00 p.m., a girl in a blue jacket comes. "I lost my eraser this morning. I can't find it," she says. Wang Lei gives her a white eraser. "Is this your eraser?" "Yes, it is! Thank you very much!" the girl says happily.
What is the main idea of the passage?
- A. It is about how to make a pen and an eraser.
- B. It is about a school Lost and Found activity and how students ask about owners of things.
- C. It is about why Wang Lei likes collecting pens.
- D. It is about what Li Mei and Zhang Hua do at home.
答案：B
解析：本题考查对短文主旨大意的把握，同时复习 Is this your ...? 询问物品归属的用法。短文围绕学校失物招领活动展开，描述了 Wang Lei 拿着失物用 "Is this your pen?" "Is this your eraser?" 询问物主，并用 Yes, it is. / No, it isn't. 回答的过程，因此主旨是「学校失物招领活动以及学生如何询问物品归属」，B 项准确概括。A 项「如何制作钢笔和橡皮」文中未涉及；C 项「Wang Lei 为什么喜欢收集钢笔」属无中生有，他只是在找物主；D 项「李梅和张华在家做什么」只是细节且偏离主题。易错点：① 选 C 或 D，被个别细节词（collecting / at home）干扰，主旨题要抓全文中心而非细节；② 忽略题目问的是 main idea（主旨），误当成细节题。故选B。

Read the news report and choose the best answer.
Greenwood Middle School opened a Lost and Found Station this Monday. On Tuesday morning, a boy named Tom found a blue pencil box on the playground. Inside it there was a pen, an eraser and a ruler. Tom took it to the station and wrote a note on the box: "Is this your pencil box? Please come to the Lost and Found Station and ask for it." After school, a girl named Lucy came. She said, "Yes, it is mine. It's my pencil box." The teacher asked, "Is this your pen, too?" Lucy looked at it and said, "No, it isn't. The pen is Lily's. It's her pen." Then Lucy took the pencil box and the teacher gave the pen to Lily.
Which of the following is TRUE according to the news report?
- A. The pencil box belongs to Lily.
- B. The pen in the pencil box is Lucy's.
- C. Tom found a pencil box on the playground.
- D. The Lost and Found Station opened on Tuesday.
答案：C
解析：本题考查对新闻报道细节的辨析，同时渗透物主代词与名词所有格的概念对比。A 项错误：文中 Lucy 说 "It's my pencil box"，铅笔盒是 Lucy 的，不是 Lily 的，易受后文 Lily 出现的干扰。B 项错误：Lucy 明确说 "No, it isn't. The pen is Lily's. It's her pen."，钢笔是 Lily 的，此处要分清 my（我的）与 her（她的）。D 项错误：失物招领站是 Monday（周一）开放的，Tom 是 Tuesday（周二）早上发现铅笔盒，属于时间概念混淆。C 项与原文 "a boy named Tom found a blue pencil box on the playground" 完全一致。故选C。
5填空题
根据短文内容，用括号内所给词的适当形式填空。
Good morning! I'm Lin Tao. Our school has a Lost and Found box this week. Look! This is a pencil. It is yellow. Is it your pencil? That is a ruler. It is long. Is that your ruler? These are two books. They are English books. Are these your books? Those are my keys. They are on the desk. Please call me at 623-4512.
1. —What's this? —______ is a pencil.
2. —What are those? —______ are my keys.
3. —Is this your ruler? —No, it ______.
4. Those are ______ (I) keys.
5. —Is that your eraser? —Yes, it is. It is ______ (she) eraser.
答案：1. It 2. They 3. isn't 4. my 5. her
解析：1. 回答 What's this/that? 时，要用代词 it 作主语，不能说 This is...，故填 It。2. 回答 What are those? 时，要用复数代词 they，be 动词已给出 are，故填 They。3. Is this your...? 的否定回答固定为 No, it isn't.，必须用 it，不能省略或改用 this。4. 此处修饰名词 keys，要用形容词性物主代词 my，不能用 I。5. 此处修饰名词 eraser，且指"她的"，要用 her，不能用 she 或 hers。易错点：一是回答 Is this your...? 时漏写 it 或误用 This；二是物主代词与人称代词混淆，形容词性物主代词后必须跟名词。
6填空题
根据短文内容，用括号内所给词的适当形式填空。
Our school has a Lost and Found Day every term. This year it is on March 12th. On that day, students bring the things they find to the hall. Look! Here are some things on the table. The books are the (1) ______ (student) books. The red ruler is (2) ______ (Lily) ruler. The English dictionary is (3) ______ (Tom and Jim). They bought it together last year. Tom likes (4) ______ (read) it after class, and Jim (5) ______ (like) it, too.
答案：(1) students' (2) Lily's (3) Tom and Jim's (4) reading (5) likes
解析：本题以校园失物招领日这一社会热点情境为背景，集中辨析名词所有格的构成规则与 like 的用法，属于概念辨析题。
(1) student 前有 the，指全班学生，用复数 students；以 s 结尾的复数名词变所有格只加 '，故填 students'，易错点是误写成 students's。
(2) Lily 是单数人名，在词尾加 's，构成 Lily's，表示“莉莉的尺子”。
(3) Tom and Jim 是两个人，字面上是复数，但词尾没有 s，且两人共有（买了同一本词典），只在后一个人名 Jim 后加 's，构成 Tom and Jim's。易错点是误写成 Tom's and Jim's（那表示两人各自拥有一本）。
(4) like doing sth. 表示“喜欢做某事”，read 要变为 reading，易错点是误填 to read 或 read。
(5) 主语 Jim 是第三人称单数，一般现在时中动词 like 要加 s，故填 likes，易错点是受并列结构影响误填 like。
7解答题
根据短文内容，按要求完成下列各句。
Hello! I'm Lucy. I am in the school library now. Look! This is my pencil. It is yellow. That is Tom's ruler. It is blue. These are my two books. They are English books. Those are Amy's keys. There is a computer on the desk. I have a new schoolbag, too.
1. 对划线部分提问：This is my pencil.（划线部分：my pencil）
2. 将句子改为一般疑问句并作否定回答：That is Tom's ruler.
3. 用 have/has 或 there is/there are 填空：
(1) I ______ a new schoolbag.
(2) ______ a computer on the desk.
4. 将下列句子译成英语：这些是你的橡皮吗？不，不是。它们是她的橡皮。
答案：1. What is this?
2. Is that Tom's ruler? No, it isn't.
3. (1) have (2) There is
4. Are these your erasers? No, they aren't. They are her erasers.
解析：1. 划线部分 my pencil 是物（表语），应用疑问词 What 提问；原句是 This is... 结构，变特殊疑问句时保留语序并把指示代词 this 放在疑问词后，即 What is this?，易错点是误写成 What this is 或漏写 is。2. 含 be 动词的陈述句变一般疑问句，把 is 提前；否定回答固定为 No, it isn't.，必须用 it 作主语，易错点是写成 No, that isn't.。3. (1) 主语 I 是人，表示"拥有"，用 have；(2) 表示"某处存在某物"，且 a computer 为单数，用 There is，易错点是错用 have 表示存在，或用 There are 而忽略名词单复数。4. "这些"用 these，回答用 they；"你的"用 your，"她的"用 her，都必须后接名词。易错点是把 Are these your eraser? 中 eraser 忘记用复数，或用 hers 替代 her。

Lost and Found News (News Report)
Our school has a Lost and Found box near the library. Every Monday morning, students come to look for their things. Here are some of the notices (启事) this week.
Notice 1: A blue pencil box is in the box. Is this (1) _______ (you) pencil box? (2) _______ (I) is green, so it isn't mine.
Notice 2: Found: a nice eraser. (3) _______ (who) eraser is it? Please ask Miss Li for it.
Notice 3: I lost (4) _______ (I) ruler. It is yellow. If you find it, please e-mail (5) _______ (I) at 123456@qq.com. Thank you!
Notice 4: Look! Is this blue pen (6) _______ (she)? Anna lost a pen last week.
答案：(1) your (2) Mine (3) Whose (4) my (5) me (6) hers
解析：本题考查物主代词与人称代词的辨析，属于本单元核心考点。逐空分析：(1) 空后有名词 pencil box，修饰名词要用形容词性物主代词，故填 your（your 也可作形容词性物主代词，your pencil box = 你的铅笔盒）；(2) 空后无名词，句子意为「我的（铅笔盒）是绿色的」，独立使用要用名词性物主代词 Mine，且位于句首需大写；(3) 对物品归属提问用疑问词 Whose，Whose eraser is it? 意为「它是谁的橡皮？」；(4) 修饰名词 ruler，用形容词性物主代词 my；(5) 动词 e-mail 后作宾语，用宾格 me，不能用主格 I；(6) 句中无名词，且表示「是她的（钢笔）吗」，用名词性物主代词 hers。易错点：① 混淆 my/mine、her/hers：有名词用形容词性物主代词，无名词独立使用用名词性物主代词；② 宾格与主格混用，动词或介词后必须用宾格 me；③ 漏看句首大写要求。
