U7 · Grammar 预习笔记(背默版 · 20 条)
教材:译林版(2024) 8A U7《The natural world》· Grammar(P64 左右)
本课定位:U7 语法课——as…as 原级比较 + provide/offer 双宾语 + 宾补三条路。这三块是中考单选与句型转换的"三件套",一课全占。
预测确定性:✅ 教材已确认(as…as + 双宾语 + 宾补) | 条数:20 条
⏱ 20 分钟:保底 8 条 5′ → 句子精读 3′ → 进阶 6 条 4′ → 冲 A 6 条 3′ → 必背句 + 快测 5′;做不动就停在保底组。
一、核心词组 · 保底 8 条(中文 → 英文)
看中文说英文,说不出的看右侧英文,再遮住中文重来一遍。
| 笔记# | 中文 | 英文 | 红笔标注 / 考点 |
|---|---|---|---|
| 1 | 珊瑚礁和雨林一样重要。 | Coral reefs are as important as rainforests. | as + 形容词原级 + as |

| 4 | 为某人提供某物(换序) | provide sth for sb | provide sth for sb |
| 5 | 为某人提供某物 | offer sb sth | 双宾语结构 |

二、归类记忆 · 三条路
第一条路 · 比较两条路(一样 / 不如)
| 路线 | 结构 | 例句 |
|---|---|---|
| A. 和……一样…… | as + 形容词原级 + as | Coral reefs are as important as rainforests. |
| B. 不如…… | not as / not so + 原级 + as | It is not as big as the ocean. |
第二条路 · "提供"的两套说法(中考常考互换)

| offer | offer sb sth(双宾语) | offer sth to sb |
第三条路 · 宾补三条路(让宾语"变成什么样")

| B. make | make + 宾语 + 名词 / 形容词 | We made the forest the topic of this class. |
| C. call | call + 宾语 + 名词 | We call it the 'lungs' of the earth. |
📖 三、句子精读(教材书例句 · 抓从句)
句子才是学英语的核心:先读出主干(谁 + 做什么),再找从句在修饰谁。每句读 3 遍。
| # | 教材书例句 | 中文 | 从句 / 考点拆解 |
|---|---|---|---|
| 1 | Coral reefs are as important as rainforests. | 珊瑚礁和雨林一样重要。 | as + 形容词原级 + as 和……一样……(否定用 not as/so … as) |
| 2 | The book provides us with much knowledge. | 这本书为我们提供了丰富的知识。 | 双宾语结构 provide sb with sth(=provide sth for sb);knowledge 为不可数名词 |
| 3 | We made the forest the topic of this class. | 我们把森林定为本次课的主题。 | 宾补结构 make + 宾语 + 名词(使……成为……);topic n. 话题 |
四、进阶 6 条
这 6 条重点看「红笔标注」,知道考什么比背下来更重要。
| 笔记# | 中文 | 英文 | 红笔标注 / 考点 |
|---|---|---|---|
| 9 | 它们使水保持干净。 | They keep water clean. | keep + 宾语 + 形容词 |

| 13 | 阻止……做…… | stop ... from doing ... | stop sb from doing |
| 14 | 使……免受…… | keep ... free from ... | keep A free from B |
五、冲 A 6 条
学有余力再攻。17、18 是"环保行动"作文里的常用句。
| 笔记# | 中文 | 英文 | 红笔标注 / 考点 |
|---|---|---|---|
| 15 | 湿地有助于清除污染。 | Wetlands help get rid of pollution. | help (to) do |
| 16 | 我们能做些什么来保护自然? | What can we do to protect nature? | to do 作目的状语 |
| 17 | 我们应采取行动清理河流。 | We should take action to clean up the rivers. | take action to do |
| 18 | 它在减缓全球变暖中起重要作用。 | It plays an important role in slowing down global warming. | role in + doing |
| 19 | 环境和经济一样重要。 | The environment is as important as the economy. | as ... as |
| 20 | 保持平衡很重要。 | It's important to keep the balance. | It 形式主语 + to do |
六、句型全家桶(本课句型对号入座)
| 句型 | 结构 | 例句 |
|---|---|---|
| 和……一样 | as + 原级 + as | English is as useful as maths. |
| 不如…… | not as / not so + 原级 + as | It is not so big as that one. |
| 为某人提供某物 | provide sb with sth | Forests provide us with oxygen. |
| 为某人提供某物(换序) | provide sth for sb | Forests provide oxygen for us. |
| 使……保持…… | keep + 宾语 + 形容词 | Forests keep the air fresh. |
| 阻止某人做…… | prevent / stop sb from doing | We must stop people from cutting down trees. |
七、易错提醒(只记正确写法)
- as ... as 中间必须用原级,不能用比较级(不能说 as bigger as)
- 否定用 not as ... as 或 not so ... as,两种都对
- provide sb with sth = provide sth for sb——介词不同、语序不同
- offer sb sth 是双宾语(offer us help);不能说 provide sb sth
- keep sb / sth + 形容词,形容词作宾补,不加 -ly
- prevent / stop sb from doing:from 可省(stop sb doing),但 doing 不能改成 do
八、同义句转换(中考句型转换的"等式")
provide sb with sth=provide sth for sboffer sb sth=offer sth to sbnot as ... as=less ... thankeep the air fresh=make the air freshprevent sb from doing=stop sb from doing
📌 本课必背 3 句
- Coral reefs are as important as rainforests.(珊瑚礁和雨林一样重要。)
- Forests keep the air fresh and provide us with much oxygen.(森林使空气清新,并为我们提供大量氧气。)
- It's important to keep the balance of nature.(保持自然平衡很重要。)
🎤 学完就能用的一句话
English is as useful as maths.(英语和数学一样有用。)
🎯 快测 5 题(汉译英 · 答案就在上面)
把下面的中文翻成英文;不会的翻回去找,找到后读 2 遍(对 3 题就合格):
- 珊瑚礁和雨林一样重要。 2. 为某人提供某物 3. 它们使水保持干净。 4. 阻止……做…… 5. 我们应采取行动清理河流。
