过去分词作定语
1)语法功能 过去分词或过去分词短语作定语时, 其功能相当于一个定语从句。 被修饰的词是分词所表示 的行为的承受者;在逻辑上,它们是动宾关系。 The stolen bike belongs to Jack. The bike which was stolen belongs to Jack. The lecture given by Professor Zhang is about environment protection. The lecture which was given by Professor Zhang is about the environment protection. a.单个的过去分词作定语时,位于它所修饰的名词或代词前面 the affected people 受感染的人 a broken heart 一颗破碎的心 a lost dog 丧家之犬 a broken glass 被打破的玻璃杯 Attention: 过去分词修饰 something, everything, anything, nothing, somebody, nobody, those 等 不定代词时,要放在这些词后面。 Is there anything unsolved?

Have you read the book recommended by your teacher?这是你老师推荐的书吗? 对比: the changing world(正在变化的)the changed world(变化了的) boiling water(正在沸腾的)boiled water(已经沸腾过的) fading flowers(正在凋谢的) faded flowers(已经凋谢的) a developing country(发展中的) a developed country(发达的) a drowning man 快要淹死的人 a drowned man 已经淹死的人 falling leaves 正在飘落的树叶 fallen leaves 落叶 a retired worker 退休工人 an escaped prisoner 逃犯 3)及物动词的过去分词(done)与现在分词的被动式 (being done)都可以表示―被动‖,但前者多表示一个完成了的动作,而后者则表示一个正 在进行的动作. the problem discussed yesterday the problem being discussed

过去分词做表语
1 过去分词(短语)作表语时,其作用相当于 adj.,说明的是主语的状态 All the windows are broken. All hope is gone. He looked worried after reading the letter. 常见作表语的过去分词有: disappointed, drunk, amused, frightened, married, excited, experienced, interested, confused, pleased, puzzled, satisfied, tired, worried,gone, dressed, lost 等。 注意 过去分词作表语时和动词的被动语态结构相似,但两者表达的意思明显不同,前者 说明主语的特点及所处的状态,而后者强调被动的动作。 My glasses are broken.我的眼镜碎了。(状态) My glasses were broken by my son.我的眼镜被我儿子摔碎了。 (动作) Part 4. Using Language 1.Although he had tried to ignore them, all his mathematical calculations led to the same conclusion.....虽然他曾经试着不去理睬那些数据,然而他所有的数字计算都得出了一个相同 的结论 lead to 导致,通向 该短语中 to 为介词。类似的短语还有:

be used to stick to look forward to devote onesele to pay attentio to 2.Only if you put the sun there did the movementof the other plants in the sky make sense..只有当 你把太阳放在中心位置上,天空中其他行星的运动才能说得清楚。 1)句中 only 修饰 if 引导的状语从句,放在句首时,后面的主句要用倒装。only 位于句首, 其后接副词或介词短语时,句子的主谓也要部分倒装。 2)make sense 讲得通;有道理;有意义 3.Yet he could not tell anyone about his theory as the powerful Christian Church would have punished him for even suggesting such an idea. 然而他的这个理论不能告诉任何人, 因为即使 他只暗示有这种想法,他都会受到强大的基督教会势力的惩罚。 would have done 表示与过去事实相反的假设 If I had seen the advertisement, I would have applied for the job.我要是看见那个广告, 我就申 请那份工作了。 虚拟语气在条件从句中的用法: if 条件句的谓语形式 与现在事实相反 与过去事实相反 与将来事实相反 动词过去式/were had+过去分词 动 词 过 去 式 或 should+动词原形 were to+动词原形 主句的谓语形式 would/should/could/m ight+动词原形 would/should/could/m ight+had+过去分词 would/should/could/m ight+动词原形

4.His friends were enthusiastic and encouraged him to publish the ideas, but Copernicus was cautious.他的朋友都热情地鼓励他把他的想法公之于众,而他却小心谨慎。 1) enthusiastic 热心的,满腔热情地 v. enthuse 热心 n. enthusiasm 狂热,热心,积极性 enthusiast 热心者,热情的人 adv. enthusiastically 热心地,狂热地 2) be enthusiastic about/over...对。 。 。热情 She’s very enthusiastic about singing. 她对唱歌很有热情。 be cautious about/of sb.(sth.)对。 。 。小心谨慎 5. complete adj.结束的;完成的;完整的 v.使完美;使完整;完成 I need one moer stamp to complete my collection.我所收集的邮票还差一张才成整套。 When will work be completed on the new road?新道路的工程何时完成? 6. reject v.拒绝;不接受;丢弃 He rejected their invitation point-blank.他直截了当地拒绝了他们的邀请。 7. base sth. on 把...基于 8. basis. 基础;基本 basically adv.基本上 basic adj. 基本的
