FCE 你会 Walking down the street, I saw...；CAE 升级到完成式分词（Having spent）、被动分词（Seen from）、独立主格（The weather being fine）。最大忌是悬垂修饰——分词主语必须和主句主语一致。学完句子立刻紧凑学术。
① 这一课怎么学（C1 冲刺 4 步法）
总用时约 90 分钟，拆成 4 步，一步都别跳：
1读（20 分钟） 看第③④部分：三种分词的时间/主被动关系，独立主格为什么不悬垂。
2练（25 分钟） 做第⑥⑩部分，重点改悬垂修饰句。
3背（20 分钟） 背第⑧部分 10 个分词句。
4说（25 分钟） 口语 Part 2 用 Seen from... / Having seen... 开头描述图片。
本课的小目标学完你要能：① Having done 压缩 after；② Seen from... 压缩 when it is seen；③ 写出独立主格 The weather being...；④ 一眼认出并改掉悬垂修饰。
② 一图看懂全课（思维导图）
这张图就是本课的完整地图：分词结构共五大块：一般式、完成式、被动式、独立主格、悬垂避坑。
分词结构

→
一般式（主动同时）
V-ing

→
被动式

独立主格
自带主语
The weather being

悬垂避坑
主语一致

读法：从根出发，五大块顺序走，每块下面是小节点，全记住你就通关了。
③ 先认识它：分词结构到底是什么
一句话：分词结构 = 用分词把次要动作压缩成状语，省掉主语和连词。普通两句 After I had spent ten years there, I knew it well → 一句 Having spent ten years there, I knew it well。
三种形式：① V-ing：主动、与主句同时（Walking, I saw）；② Having + 过去分词：主动、先于主句（Having finished）；③ 过去分词：被动（Seen from afar）。
独立主格自带主语：The weather being fine, we went out——The weather 是 being 的主语，和主句主语 we 不同，所以不悬垂。
为什么它是 C1 拿分点Part 4 KWT：After I had finished → Having finished，2-5 词内完成。作文用分词压缩句子，是 Cohesion 拿 C1 的关键。
④ 完整体系表
分词结构全表：
结构
规则
例句
一般式（主动，同时）
V-ing + 主句
Walking down the street, I met an old friend.
完成式（主动，先于）
Having + p.p. + 主句
Having finished the essay, she went to bed.
被动式
p.p. + 主句
Seen from the hill, the city looks tiny.
完成被动式
Having been + p.p.
Having been told the news, she left.
独立主格
(主语) + V-ing/p.p. + 主句
The test being over, the students cheered.
必背细节① 分词的逻辑主语必须和主句主语一致，否则悬垂。② Having + p.p. 表"在主句动作之前已完成"。③ 被动用过去分词（Seen），主动用 V-ing（Seeing）。
⑤ 用法场景全解
场景
例句
记忆点
压缩 after
Having spent years abroad, she returned.
= After she had spent
压缩 when（被动）
Seen from afar, it looked tiny.
= When it was seen
伴随/原因
Not knowing the way, he asked a policeman.
= Because he did not know
独立主格
The lecture being over, we left.
自带主语，表时间
评论开头
Having seen the exhibition, I can say...
Review 高分开头
使用提醒悬垂修饰是 C1 写作大忌：Walking down the street, the gallery looked big（画廊不会走路）。写完检查：分词动作是不是主句主语发出来的？不是就补主语或改独立主格。
⑥ 中国学生 5 大高频错误诊断
错误 1：悬垂修饰（主动）✗ Walking down the street, the church looked beautiful. → ✓ Walking down the street, I saw a beautiful church. walking 的主语应是人，不是教堂。
错误 2：悬垂修饰（被动）✗ Seen from the hill, I saw a tiny village. → Seen from the hill, the village looked tiny. 被看的是村庄，不是 I。
错误 3：完成式当一般式✗ Having walked home, I am tired now.（同时）→ ✓ Walking home, I enjoy the sunset. 同时发生用 V-ing，不用 having。
错误 4：独立主格漏主语✓ The weather being fine, we went out.（对）但写成 Being fine, we went out 就悬垂。 独立主格要自带主语。
错误 5：主被动选错✗ Seen the film, I left.（主动看）→ ✓ Having seen the film, I left. "我看电影"是主动，用 having seen。

真题风格演练（CAE 出题方式）
真题风格 · CAEKWT：After she had finished her degree, she travelled for a year. KEY: HAVING → ___ her degree, she travelled for a year.
答案：Having finished（after she had finished = having finished）。
真题风格 · CAE改错：Walking along the beach, the waves looked magnificent.
答案：Walking along the beach, I saw magnificent waves.（waves 不能 walk）。
真题风格 · CAE填空（独立主格）：The meeting ___, everyone went home.（结束了）
答案：being over / ended（独立主格，自带主语 the meeting）。
考场提分提醒KWT 看到 after / when / because 先想分词：主动先于用 having done，被动用 p.p.。作文写完专门搜一遍 V-ing / p.p. 开头的句子，确认主语一致。

考场示范（读熟就能套）
Examiner: Compare these two pictures for about a minute.
You: The painting on the left, seen from a distance, glows warmly. Whereas the first celebrates abundance, the second, having been painted in cold tones, questions emptiness. The contrast could not be more marked.
