Ⅰ. 语法填空。
Hello, I am Alice! It's 8 o'clock in the morning and I am in the classroom. The students are all busy at the moment. Mary (open) the windows. Eric is reading English words. Some students are talking. Others (listen) to them. Some (read) books, and some are doing their homework.
Miss Li is our English teacher. She is standing in front of the classroom and (talk) with Teng Fei. Beth and Adam (share) their holidays. They are having a great time! What am I doing? Oh, I am talking with my best friend, Lily.

Ⅰ. is opening, are listening, are reading, talking, are sharing

【分析】
首先通读全文，找到文中的时间提示："It's 8 o'clock in the morning"、"at the moment"，说明所有描述的动作都是此刻正在发生的，确定全文统一使用现在进行时，结构为"am/is/are + 动词现在分词"。接下来逐个分析每个空的主语人称和数，匹配对应的be动词，再把给出的动词变为正确的现在分词形式，同时注意并列谓语的省略规则：当同一个主语并列多个现在进行时的动作时，只需要在第一个动作前加be动词，后面的动作直接用现在分词即可，不需要重复写be动词。
【解析】
1. 第一空：主语Mary是第三人称单数，be动词用is，动词open的现在分词为opening，所以填is opening。
2. 第二空：主语Others指代前文的其他学生，是复数概念，be动词用are，动词listen的现在分词为listening，所以填are listening。
3. 第三空：主语Some指代部分学生，是复数概念，be动词用are，动词read的现在分词为reading，所以填are reading。
4. 第四空：主语是She，前面已经出现了be动词is，并列的两个动作是standing和talk，共用同一个is，因此直接填talk的现在分词talking即可，不需要重复加be动词。
5. 第五空：主语Beth and Adam是两个人，复数概念，be动词用are，动词share的现在分词为sharing，所以填are sharing。
【答案】
is opening, are listening, are reading, talking, are sharing
【知识点】
现在进行时结构，主谓一致，并列谓语省略
【点评】
本题是现在进行时的基础语境应用题，通过明确的当下时间状语提示，引导学生掌握现在进行时的构成规则，区分不同人称主语对应的be动词形式，易错点在于第四个并列动作的谓语省略，不少学生会误多写be动词are，需要学生注意观察句子结构，确认动作是否共享同一个主语和be动词。

Ⅱ. 观察教室里的老师和同学们，仿照示例，用现在进行时造句(至少写三句)。
示例：David is doing his homework and Emma is talking with her friends.
Some are doing their homework and others are reading books.
_______
_______
_______
写作实践

【分析】
首先明确本题的核心要求：使用现在进行时，造句内容要贴合教室内师生活动的真实场景，数量不少于3句。解题时第一步先回忆现在进行时的基本结构为「主语 + be动词(am/is/are) + 动词现在分词 + 其他」，同时参考示例给出的两种常用句式：一是用and连接两个不同人物正在做的不同动作，二是用Some...others...的结构描述群体不同的行为。第二步结合教室常见的场景，比如老师板书、学生值日、讨论作业、听课记笔记等日常课堂行为，确保每句的be动词和主语单复数匹配，动词现在分词变形正确，内容符合场景设定即可。
【解析】
1. 第一句选取老师和单个学生的不同行为，主语Miss Li是第三人称单数搭配be动词is，write的现在分词为writing；Xiao Ming是第三人称单数搭配be动词is，clean的现在分词为cleaning，整句结构完全符合现在进行时要求，场景符合课堂真实情况。
2. 第二句采用示例给出的Some...others...群体描述结构，Some students是复数搭配be动词are，discuss的现在分词为discussing；others指代其余学生为复数搭配be动词are，read的现在分词为reading，贴合自习课学生不同学习行为的场景。
3. 第三句选取同桌两个学生的课堂行为，Lucy是第三人称单数搭配be动词is，listen的现在分词为listening；her deskmate是第三人称单数搭配be动词is，take的现在分词为taking，符合正常上课学生听课记笔记的场景。
三句均满足题干的时态要求和场景要求，符合题意。
【答案】
1. Miss Li is writing on the blackboard and Xiao Ming is cleaning the window.
2. Some students are discussing the homework and others are reading their Chinese books.
3. Lucy is listening to the teacher carefully and her deskmate is taking notes on the notebook.
【知识点】
现在进行时结构，主谓一致，课堂场景表达
【点评】
本题属于基础的时态应用型题目，跳出了单纯考语法填空的形式，引导学生结合真实生活场景活用现在进行时知识点，解题时需要注意准确匹配主语和对应的be动词，同时牢记动词现在分词的正确变形，避免出现语法错误，内容也要贴合教室观察的设定，不要脱离场景编造不合理的句子。
