# 八年级下累积测评 自然观察与社区准备
8年级下学期原创累积非听力测评。材料未在前课例题中出现；场景、人物和数据均为学习任务自编，不是实际活动通知。
## 学习目标
- 独立完成本学期及前置知识的陌生语篇读写任务。
- 为答案写出可核对的语法理由或原文证据，并识别范围限制。
- 依照分项量表评分，使用补救链接订正后再以陌生材料复测。
## 核心讲解
本卷20个编号任务，每题5分，合计100分。第1—16题为基础区80分，至少64分并订正错因视为达到基础训练门槛；第17—20题为迁移区20分。冲刺目标为全卷95分以上，且能够解释证据、在另一份陌生材料中复现表现。它们不是中考成绩保证，也不能换算为含听力整卷成绩。
先独立完成再展开答案。非写作题除答案外均写一句理由或原文依据，理由已包含在5分内；开放题按内容、语言和连贯量表计分，示例不唯一。建议给自己一个与篇幅相称的训练时段，记录实际用时，再依据错因调整；本卷不规定官方考试时长。不要预读参考答案来制造分数。
## 例题解析
**仅示范评分方法，不属于本卷20题**：短文说“Among ten students, only two stayed”。问“是否所有学生留下？”答“不是，因为only two仅指两人”同时给出判断和范围证据；若只写“不是”，判断分可得，证据分未完成。开放写作先核对要点，再看句子与组织，不要求与范文逐字相同。
## 练习
### 材料一 完形短文（第5—8题）
Our class started a book discussion group. The first book was about a young traveller who learned to respect different ways of life. At first, we tried to finish every chapter as quickly as possible. (5), our teacher asked what evidence supported our opinions. We realised that speed alone was not enough. Each member chose a paragraph (6) mattered to them. The paragraphs (7) on a classroom board, and everyone read them silently and wrote comments. We learned to disagree politely and explain (8) we understood a character’s choice.
本材料所有阅读与评论均以书面完成。
### 材料二 原创社区提示（第9—12题）
**Community Hall Update**
Because a strong storm is expected on Saturday, the outdoor history walk has been postponed. The indoor photo display will remain open from 10:00 to 12:00 unless the building manager announces otherwise. Visitors should check the latest notice before travelling. Children under twelve must stay with an adult. Do not enter areas marked “Closed”. Questions about access can be sent to the organiser.
本提示为语言练习的虚构信息。真实灾害情境以当地应急部门及现场管理通知为准。
### 材料三 原创自然观察文本（第13—16题）
A student group wanted to make a garden look perfectly neat. They removed some fallen branches, then noticed small insects hiding under the remaining wood. Their science teacher asked them to compare two corners: one that had been cleared and another that still had leaves and branches. During several short observations, the second corner contained more kinds of visible insects. The students did not claim that every untidy place was healthy. Instead, they decided to keep a small natural corner while removing rubbish from paths. A sign explained why the two tasks were different.

The group then changed its plan. It kept one small natural area but continued to remove rubbish from paths. This decision was based on what the students observed, not on a rule that every untidy place is healthy. The sign helped other visitors understand the difference between useful shelter and unwanted litter. 内容2分，时态及复杂句2分，证据范围与连贯1分。
