读一读，选出正确的答案。Lucy is showing her new classroom to her robot friend, Ruru. Lucy says: "Ruru, this is my classroom. Look! This is a big ______. We write on it. And these are our ______. We sit on them." Which words can fill in the blanks?
- A. blackboard; chairs
- B. blackboard; chair
- C. blackboards; chair
- D. window; chairs
答案：A
解析：第一空：由“We write on it（我们在它上面写字）”可知是黑板 blackboard，且前面有 a，用单数 blackboard；blackboard 是 black + board 合成的长词，注意拼写，不要漏写 k 或 d。第二空：由“we sit on them（我们坐在它们上面）”可知是椅子 chair，them 是复数，所以用 chairs，且前面是 these，these 后面的名词必须用复数。B 选项第二空 chair 没变复数，与 these、them 不搭配；C 选项第一空 blackboards 不需要复数，第二空单复数错误；D 选项第一空 window（窗户）不是用来写字的。故选A。

阅读下面的小对话，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Tom is in a new classroom with his robot friend, MiMi. Tom wants to know the names of the things in the room.
Tom: MiMi, what's this?
MiMi: It's a blackboard. It is long and black.
Tom: What's that near the window?
MiMi: It's a desk. And this is my chair.
Tom: Great! This is my new classroom.
Question: What is near the window?
- A. A blackboard.
- B. A desk.
- C. A chair.
- D. A door.
答案：B
解析：本题考查教室物品词汇 blackboard、desk、chair、window、door 在新情境（与机器人 MiMi 对话）中的辨认。定位关键句 "What's that near the window? — It's a desk." 可知窗户旁边的是 desk。易错点：① 混淆 this 与 that 的指向，把 "this is my chair" 误当成窗户旁边的物品；② 只看到第一句 blackboard 就选 A，未读到 near the window 这一限定信息。故选B。
3选择题
Read the passage and choose the best answer. (阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。)
This is our new smart classroom. There is a big screen on the wall. We can see English words on it. The teacher says, "Touch your knees!" We touch our knees. Then she says, "Clap your hands!" We clap our hands. Lily is wearing a new T-shirt. She sits at a desk near the window. She has a book and two pencils on her desk.
Question: Which of the following does the teacher ask the children to do first?
- A. Clap their hands.
- B. Touch their knees.
- C. Touch their heads.
- D. Sit near the window.
答案：B
解析：题干问老师让孩子们先做哪个动作（do ... first）。回到短文顺序：先说 "Touch your knees!"，然后（Then）才说 "Clap their hands!"，所以先做的是 touch their knees，对应 B。A 是第二个动作，属于顺序混淆；C 文中未出现，属于凭印象误选 head（head 与 hand、knee 混淆）；D 是 Lily 的座位位置，不是老师下的指令。易错点：① 忽略 first / then 这类表示先后顺序的词；② 把文中人物自己的动作（sits near the window）误当成老师的指令；③ 复数 knees、hands 不要漏看。故选B。
4填空题
根据对话内容，用括号内所给词的适当形式填空，补全下面的对话。
Lily and her robot are talking about a day at school.
Robot: When do you get up?
Lily: I get (1)______ at seven (2)______ (clock).
Robot: When do you have breakfast?
Lily: I have breakfast (3)______ seven thirty.
Robot: When do you go to bed?
Lilly: I go to bed (4)______ nine o'clock. This is my day!
答案：(1) up (2) o'clock (3) at (4) at
解析：本题把一天作息短语 get up / have breakfast / go to bed 放进与机器人对话的新情境中考查。关键突破口是「时间点前必须用介词 at」：at seven o'clock、at seven thirty、at nine o'clock，故 (3)(4) 均填 at。get up 是固定短语，(1) 填 up；(2) 考查 o'clock 的拼写，注意撇号不能漏，写成 oclock 或 clock 都不得分。易错点：① 时间前漏写 at（如写成 seven thirty）；② 把 have breakfast 误写成 eat breakfast；③ o'clock 漏撇号或误加复数。

写一写。小机器人 Ruru 第一次走进二年级(3)班的教室，它用英语做了下面的自我介绍，请你根据提示补全它说的话，每空填一个单词（注意大小写和单复数）。
Hello! I am Ruru. This is my ______. Look! This is a blackboard. It is big. This is a ______. I can sit on it. This is a ______. We can see the trees through it. This is my ______. I put my books in it. I like my classroom!
提示词（word box）：desk / classroom / window / door
答案：参考答案：
1. classroom（This is my classroom. 这是我的教室。）
2. desk（This is a desk. I can sit on it. 我可以坐在它上面。）
3. window（This is a window. We can see the trees through it. 我们可以透过它看到树。）
4. door（This is my door. 我的门。）
完整短文：
Hello! I am Ruru. This is my classroom. Look! This is a blackboard. It is big. This is a desk. I can sit on it. This is a window. We can see the trees through it. This is my door. I put my books in it. I like my classroom!
解析：本题把教室物品单词放进“机器人参观新教室”的科技创新情境，考查对 blackboard / desk / window / door 的词义理解和 This is a… 句型的运用。做题时先看每空后面的解释句，再从 word box 里挑词：能“坐在上面”的是 desk；能“透过它看到树”的是 window；“把书放进去”的是 door；开头总说“这是我的教室”填 classroom。易错点：① blackboard 是 black + board 合成词，拼写较长，容易漏写字母；② This is 后面的名词要加 a/an（This is a desk，不能写 This is desk）；③ window（窗户）与 winter（冬天）读音、拼写接近，不要混淆；④ 每空只填一个单词，注意句首字母大写。
6解答题
Look at the classroom words below: blackboard, desk, window, door, chair, book, pencil.
情境：机器人小助教 Robo 只会用英语认识教室里的东西。它指着教室里的东西提问，请你用 It's a/an ... 或 They're ... 回答。
请根据下列句子，用括号内所给词的适当形式填空，补全对话：
1. —What's this? —It's a ______ (blackboard).
2. —What's this? —It's an ______ (book).
3. —What are these? —They're ______ (pencil).
4. —What's this? —It's a ______ (desk).
5. 请用 This is ... 写两句话，向 Robo 介绍你的教室（至少介绍两样教室里的东西，如 blackboard、window、door 等）。
答案：1. blackboard
2. book（注意：本小题按 a/an 判断，book 前应用 a，故完整句子为 It's a book. 若学生按括号词填空，答案为 book。）
3. pencils
4. desk
5. 参考答案：This is my classroom. This is a blackboard. This is a window.（答案不唯一，符合 This is ... 结构、介绍教室物品即可）
完整参考对话：
1. —What's this? —It's a blackboard.
2. —What's this? —It's a book.
3. —What are these? —They're pencils.
4. —What's this? —It's a desk.
5. This is my classroom. This is a blackboard and this is a window.
解析：本题把教室物品词汇放进「机器人小助教认识教室」的科技情境，考查 What's this? —It's a/an ... 问答与 This is ... 介绍句型的迁移运用。
易错点：
① blackboard 拼写较长，是 black + board，学生容易漏写中间的 k 或写成 blackbord；
② a 与 an 的选择要看后面单词的发音首音素，book 以辅音音素开头，前面用 a 而不是 an（本题第2小题若设 an + book 则为陷阱，正确句子应为 It's a book）；
③ pencil 变复数要加 -s，写成 They're pencils，不能漏复数；
④ 介绍教室时 This is 后接单数物品，多件物品可并列或分句说，不能写成 This are。
7解答题
情境：学校科技节上，二年级同学设计了一个「智慧教室」模型。请你根据提示，用英语完成下面的介绍。
已知信息：
· 教室里有一块 blackboard（黑板），它是新的（new）。
· 教室里有六张 desk（课桌）。
· 教室里有一扇 window（窗户）和一扇 door（门）。
请完成下列任务：
1. 用 This is ... 或 These are ... 把上面三行信息各写成一句英语介绍（共三句）。
2. 你的同桌问你 What's this?（指着黑板），请写出你的回答。
3. 仿照 My favourite food is dumplings. 的句型，用 My favourite ... is ... 写一句话，说说你在这个智慧教室里最喜欢的一样东西（如 My favourite classroom thing is the new blackboard.）。
答案：1. This is a new blackboard. / These are six desks. / This is a window and a door.
2. It's a blackboard.
3. My favourite classroom thing is the new blackboard.（答案不唯一，句型正确、所写物品在教室内即可，如 My favourite classroom thing is the window.）
完整参考作答：
1. This is a new blackboard. These are six desks. This is a window and a door.
2. —What's this? —It's a blackboard.
3. My favourite classroom thing is the new blackboard.
解析：本题以「智慧教室模型」这一科技创新情境，把教室物品词汇（blackboard/desk/window/door）与 This is ... / It's ... / My favourite ... is ... 句型结合，考查知识迁移与灵活表达。
易错点：
① blackboard 是 black + board 合成词，拼写较长易错，注意不要漏字母；
② 单复数要分清：一张课桌是 a desk，六张课桌是 six desks，用 These are 而不是 This is；
③ favourite 拼写较长，英式写法是 favourite，不要写成 favorite 或 favourit；
④ 回答 What's this? 时用 It's a/an ...，不要直接只写物品名词，也不要写成 This's；
⑤ My favourite ... is ... 中 favourite 后接物品名词，is 不要漏，也不要写成 My favourite ... are（即使后面是复数，也要用 My favourite ... is ... 或改成 My favourite ... are ... 时注意主谓一致，二年级阶段建议用单数物品作答）。

Read the passage and finish the tasks. (阅读下面短文，完成后面的题目。)
Hello! This is my new classroom. It is big and bright. This is the blackboard. It is on the front wall. This is my desk. My book is on the desk. This is my chair. It is beside the desk. The window is near the door. Our teacher says, "Touch your head. Clap your hands." We do it together. We like our classroom.
Task 1: Answer the question in English. What is on the front wall?
Task 2: Answer the question in English. What is on the desk?
Task 3: Look at the two underlined sentences "Touch your head." and "Clap your hands." Then write one more action sentence in the same way, using the words: touch / your / shoulder.
(注意：第1、2小题用完整句子回答；第3小题把所给单词排成一个正确的动作指令，注意句首字母大写和句末标点。)
答案：Task 1: The blackboard is on the front wall. / It is the blackboard.
Task 2: My book is on the desk. / It is my book.
Task 3: Touch your shoulder.
解析：本题把「My classroom 教室物品 + 身体部位动作指令」放进一个新情境（新教室 + 课前热身儿歌），考查知识迁移。第1、2题是细节定位，需回到原文找 on the front wall / on the desk 对应的物品，用完整句子回答。第3题考查祈使句结构：动词原形 + your + 身体部位，给出 touch / your / shoulder 三个词，正确排列为 Touch your shoulder。易错点：① hand 与 head 混淆，读题要看清是 head 还是 hands；② shoulder 拼写易错（shoul-der），注意不要写成 sholder；③ 成对部位要用复数（hands / toes / knees），但 shoulder 在本题只用单数 your shoulder；④ 句首忘了大写、句末漏写句号会被扣分。
