任务一:根据语境,用所给词的正确形式+already/yet/ever/never 填空。
任务二:从上述片段中摘抄例句,提炼核心用法,适配读书报告写作。

任务三:结合自己的阅读经历,用下面四个副词各写一句话,用于读书报告。
1. already:
2. yet:
3. ever:
4. never:

任务一：
1. have read
2. have already finished
3. have never read
4. ever read
5. haven't started
6. yet
任务二：
1. I have already finished reading Robinson Crusoe.
2. I haven't started my book report for Harry Potter yet.
3. Have you ever read a science fiction book for your book report?
4. I have never read such a wonderful adventure book before.
5. I have read many great books since Grade Seven.（或My deskmate has written a book report for The Three-Body Problem. 符合现在完成时基本结构即可）
任务三（参考示例，合理即可）：
1. I have already finished reading the famous novel *The Old Man and the Sea*.
2. I haven't handed in my reading report about *Harry Potter* yet.
3. Have you ever read a book that makes you want to travel around the world?
4. I have never read a more warm and touching children's story than *The Little Prince*.

本题考查八年级核心语法现在完成时的用法，以及副词already、yet、ever、never的适用场景：
1. 现在完成时基本结构为have/has + 动词过去分词，用于描述从过去发生、持续到现在，或对现在造成影响的动作，常搭配since、before等时间状语。
2. already表示“已经”，多用于肯定句，说明已完成的动作；yet表示“还”，多用于否定句、疑问句句末，说明尚未完成的动作；ever表示“曾经”，多用于疑问句询问是否有过相关经历；never表示“从未”，用于肯定句表否定含义，强调没有过相关体验。
我们结合语境逐空推导：
任务一：
1. 句中since Grade Seven是现在完成时标志，主语为I，直接用现在完成时结构have read。
2. 该句为肯定句，表达“我已经读完《鲁滨逊漂流记》”，用already修饰，变为have already finished。
3. 该句要表达“我之前从未读过这么棒的冒险书”，用never表否定含义，变为have never read。
4. 该句为疑问句，询问对方是否读过科幻书，用ever修饰，变为ever read。
5. 该句为否定句，表达“我还没开始写《哈利波特》的读书报告”，现在完成时否定结构为haven't started。
6. 否定句句末用yet，对应“还（没开始）”的含义。
任务二：从填好的原文中直接匹配对应用法的例句即可。
任务三：结合阅读经历，用指定副词写出符合现在完成时规则的通顺句子即可，以下为参考示例。
