Part 2 判断下列V-ed所做成分 （时间状语） （原因状语） （条件状语） （让步状语） （伴随或方式状语） 5 6 结论: 1.V-ed过去分词做状语，可表示 ________________________等意义, 相当于一个___________________________等状语从句。 2.位置：通常放在主句之前或之后，用____________与主句隔开。 3.V-ed分词(短语)作状语时，也可在其前面加上连词when, because,if, though, unless等，以便明确作何种状语。 时间、原因、条件、让步 时间、原因、条件、让步 逗号 7 主语是同一个人（we/he/they 等） 原句： When he was asked about his plan, he kept silent. 改写（过去分词作状语）： Asked about his plan, he kept silent. 情ty is popular among students. 主语是同一个事物（it/this activity/the park 等） 原句： Because the activity is held every year, it is popular among students. 改写（过去分词作状语）： Held every year, the activity is popular among students. 8 Because the park is seen from the top of the hill, the park looks beautiful. 简化成过去分词作状语： Seen from the top of the hill, the park looks beautiful. 逻辑： 前后主语都是the park 去掉连词Because和主语the park 去掉被动结构里的is，动词变成过去分词seen 核心公式: Done（过去分词短语）, 主句（主语 + 谓语...） Done 是过去分词短语，它的逻辑主语 = 主句的主语 这个逻辑主语和分词动词之间，是被动关系（被做） 更多例子 9 先吃透这 4 步公式 确定两个主语一致（从句主语 = 主句主语） 找出 be done（从句里的被动结构） 去掉 be done 的主语，再去掉 be（只留下 done） 若有引导词（when/because/if/although），去掉引导词 最终效果： When/Because/If + 主语 + be done, 主句 → Done, 主句 10 跟着步骤，逐句拆解例子 例 1：时间状语从句改写 原句：When we were informed that we had a chance, we felt excited. 两个主语：都是we，一致 ✅ 被动结构：were informed（be done） 去掉从句主语we，去掉were → 剩下informed 去掉引导词When 改写结果： Informed that we had a chance, we felt excited. 11 例 2：原因状语从句改写 原句：Because the park is seen from the hill, the park looks beautiful. 两个主语：都是the park，一致 ✅ 被动结构：is seen（be done） 去掉从句主语the park，去掉is → 剩下seen 去掉引导词Because 改写结果： Seen from the hill, the park looks beautiful. 12 例 3：条件状语从句改写 原句：If we are given more time, we can finish the work. 两个主语：都是we，一致 ✅ 被动结构：are given（be done） 去掉从句主语we，去掉are → 剩下given 去掉引导词If 改写结果： Given more time, we can finish the work. 13 例 4：让步状语从句改写 原句：Although he was defeated many times, he never gave up. 两个主语：都是he，一致 ✅ 被动结构：was defeated（be done） 去掉从句主语he，去掉was → 剩下defeated 去掉引导词Although 改写结果： Defeated many times, he never gave up. 14 原句（带从句） 按步骤改写后的句子（过去分词作状语） When the letter was written in a hurry, the letter had many mistakes. Written in a hurry, the letter had many mistakes. Because she was worried about her son, she couldn’t sleep. Worried about her son, she couldn’t sleep. If the plan is carried out successfully, the plan will change the school. Carried out successfully, the plan will change the school. When the city is seen at night, the city looks more beautiful. Seen at night, the city looks more beautiful. 15 避坑指南：哪些情况不能用？ ❌ 错误示例（主语不一致）： Seeing from the hill, the park looks beautiful. （主语the park不能主动发出see这个动作，逻辑错误） ✅ 正确示例（主语一致 + 被动）： Seen from the hill, the park looks beautiful. （主语the park是 “被看”，用过去分词seen） 16 六、高考高频固定搭配（不用纠结主语） 这些搭配是约定俗成的，直接记就行： Compared with/to… 与…… 相比 Compared with cars, bikes are more convenient. Faced with… 面对…… Faced with difficulties, we should not give up. Located in… 坐落于…… Located in the center of the city, the park is popular. 17 四、配套练习 练习：按图中 4 步，把下列句子改写成过去分词作状语 When the work is finished, the work will be handed in. Because the boy was praised by the teacher, the boy felt happy. If the project is supported by the government, the project will go well. Although the team was beaten by the other class, the team didn’t lose hope. When the glass is broken, the glass can’t be used again. 18 参考答案 Finished, the work will be handed in. Praised by the teacher, the boy felt happy. Supported by the government, the project will go well. Beaten by the other class, the team didn’t lose hope. Broken, the glass can’t be used again. 19 五、易错提醒（对应步骤的坑） 步骤 1 最关键：主语必须真的一致 ❌ 错误：When I was informed, the news excited me. （从句主语I ≠ 主句主语the news，不能改写） 步骤 2：必须是被动（be done） 如果从句是主动（do/does/did），不能用过去分词，要用现在分词 doing。 步骤 4：引导词要去掉，但如果想保留逻辑，也可以加回去 比如：When seen from the hill, the park looks beautiful.（也可以保留 When） ________________（从天上看）, our school looks like a beautiful garden.
