八下Unit 5
Secrets caught in time + Plants for life
阅读语篇精讲 | 宾语从句突破 | 中考提分训练
2025新课标 · 2026新教材 · 浙江新中考命题趋势
⚠ 提分导语宾语从句是浙江中考必考语法点，近五年每年都出现在单选、完形和阅读中。本单元两篇阅读不仅语言丰富，更是培养'人与自然'主题意识的优质语篇。普通班提分的关键：吃透课文=搞定词汇+搞定句型+搞定语法。今天这篇文章，帮你一篇搞定！
Part 1 Secrets caught in time 语篇精讲
【新课标视角】说明文阅读+科学探究主题，浙江中考高频话题
一、语篇速览（1分钟抓住骨架）
体裁：说明文（Exposition）。全文5段，以琥珀为线索，串联三个科学发现，最后升华主题。中考说明文最爱考'说明对象+说明顺序+段落作用'，这篇文章是绝佳范本。
主线逻辑：引出琥珀 → 三大发现（恐龙羽毛/古花/新蚁种）→ 科学意义升华。
二、中考必背重点词组（默写清单）
| | |
| | These beautiful golden stones quietly keep pieces of the past. |
| | help scientists unlock the secrets of nature |
| | A piece of amber from Northern Europe... a window on the past |
| | This species no longer grows in this area. |
| | Thanks to amber, more than 300 unknown species have been discovered. |
| | Scientists used to believe that ants came from the northern half of the earth. |
| | We should put more effort into research. |
三、必考重点句型（含语法拆解）
| |
These beautiful golden stones quietly keep pieces of the past. | 主谓宾结构；pieces of the past（历史的碎片），中考完形高频短语。 |
They can tell us whether dinosaurs had feathers, but that's not all. | whether引导宾语从句，陈述语序；that's not all（还没完呢），口语常用。 |
This species no longer grows in this area, but the find proves that it did 35 million years ago. | no longer（不再）= not...any longer；prove that...（证明...）中考高频动词。 |
Scientists used to believe that ants came from the northern half of the earth. | used to do（过去常常）中考必考；that引导宾语从句。 |
Who knows whether this piece of amber will tell us more secrets? | whether引导宾语从句；rhetorical question（修辞疑问句）增强语气。 |
四、阅读技巧点拨
⚠ 考点提示浙江中考说明文常考题型：1. 词义猜测题：根据上下文推测unknown, prove, key等词义（本文均有典型语境）。2. 细节理解题：注意数字、地点、物种名称等专有名词的定位。3. 主旨大意题：末段'As a window on the past...'是主题升华句，中考高频出题点。4. 推理判断题：'Who knows whether...'这类反问句常考作者态度。
Part 2 Plants for life 语篇精讲
【新课标视角】人物传记+科学家精神，家国情怀与科学态度双重育人
一、语篇速览
体裁：人物特写（Character Profile）。全文4段，以时间为轴，展现王文采院士70余年的植物探索生涯。2025新课标特别强调'讲述中国故事，传播中华文化'，本文是教材中弘扬科学家精神的典范语篇，中考阅读理解人物传记类近年有上升趋势。
二、中考必背重点词组（默写清单）
| | |
| | |
| | To carry out his research, he spent years in wild mountains. |
| | he still carried on with his research for another 10 years |
| | He lost sight in his right eye at the age of 83. |
| | Once, he fell seriously ill while doing field work in Yunnan. |
| | Wang seldom thought about personal honour or wealth. |
| | He passed away at the age of 96 with the falling leaves of autumn. |
三、必考重点句型（含语法拆解）
| |
| make + 宾语 + 宾补；= Plants were the most important part of his life. 标题含义题常考。 |
For over 70 years, Professor Wang explored China's plants with great passion and hard work. | with + 名词短语表伴随；中考写作高分表达：with great passion and hard work。 |
He discovered and named about 1,370 new plant species. | discover（发现已存在的事物）vs invent（发明新事物）；中考完形高频考点。 |
Wang never stopped his work, and he didn't let anybody know. | stop doing（停止做某事）vs stop to do（停下来去做）；let sb. do（让某人做）。 |
Plants grow and sleep with the seasons. So did Professor Wang. | 倒装句 So + 助动词 + 主语（...也一样）；= Professor Wang also grew and slept with the seasons. 中考语法难点。 |
四、人物传记阅读技巧
⚠ 考点提示人物传记类阅读中考命题角度：1. 细节事实题：成就、时间、奖项（如1370 species, First Class Award等）。2. 品格推断题：通过'hardly mentioned', 'quiet about'等推断人物品格。3. 写作手法题：标题'Plants for life'的含义；'seasons'意象的象征意义。4. 情感态度题：作者对主人公的评价用词（great passion, hard work, unassuming resilience）。
Part 3 单元语法精讲：宾语从句（Object Clauses）
【中考必考】浙江近五年中考真题中，宾语从句出现率100%，必须拿下！
一、什么是宾语从句？
放在动词后面、充当宾语的一个完整句子，就是宾语从句。本单元学习that / if / whether三种引导词。
二、that引导的宾语从句（陈述事实）
that引导的是肯定或陈述的内容，that本身无词义，可省略（口语中常省略，但书面语保留更正式）。
| | |
Scientists now know that this idea is wrong. | | |
Research shows that they are a completely new species. | | |
They also help us understand that life on earth has always changed. | | |
三、if / whether引导的宾语从句（表示'是否'）
if和whether都表示"是否"，宾语从句中两者基本可以互换。但注意：介词后、不定式前、whether...or not结构中，只能用whether！
| | |
Scientists aren't sure if there is life in outer space. | | |
Who knows whether this piece of amber will tell us more secrets? | | |
I wonder whether he will come or not. | | |
⚠ 易错警示1. 宾语从句必须用陈述语序（主语在前，谓语在后），即使原句是疑问句！错误：I don't know where is he.正确：I don't know where he is.2. if/whether在宾语从句中翻译为'是否'，不要和条件状语从句的'如果'混淆。3. 浙江中考真题特别喜欢在'动词+宾语从句'结构中设空，重点动词：know, believe, think, hope, wonder, understand, discover, prove, show。
