I. Review 1.谓语动词与非谓语动词 2.非谓语动词：一个简单句（没有并列连词and, but, so, or, 和从属连词that, which,what等）有且只有一个谓语动词，再出现动词则是非谓语动词。 II.过去分词(The past participle) 过去分词是分词的一种，属于非谓语动词，表现形式是done，即动词的过去分词形式。过去分词既保留了动词的用法，又具备了形容词或副词的功能。因此，在句中常用作表语、定语、状语以及补语。 III.定语(Attribute) 用来修饰、限定、说明名词或代词的品质与特征。汉语翻译中常用“......的”来表示。定语由形容词，数词，形容词性物主代词，介词短语，非谓语动词，从句等充当，可分为前置定语和后置定语。 ★即学即练：划出下列句子中的定语，并判断其类型。 1.We should form a positive attitude towards our study. 2.Everyone has the right to choose their own lifestyle. 3We often discuss school events in our class meeting. 4.Several foreign guests will visit our school next week. 5.The young man with a smile is our new head teacher. 6.The students studying abroad are hard-working. 7.The plan made by our teacher is very practical. 8.We have many chances to improve our English. 9.The book that helps us relax is very popular. IV.过去分词用作定语(Attribute) 1.单个的过去分词用作定语通常置于被修饰的名词的 前面 ;过去分词短语用作定语时,一般置于被修饰的名词的 后面 .且过去分词与被修饰的名词是____被动_________(主动/被动)的关系。 And the shortened name is “the United Kingdom”or “the UK”. It consists of four countries,which share the same flag, known as the Union Jack,... The temple built hundreds of years ago is still in good condition. The art festival held last month showed our country’s rich history. 2.及物动词的过去分词,表示被动和完成;不及物动词的过去分词只表示完成,不表示被动. Fires caused by the California earthquake did a lot of damage My mother is a retired teacher. There are fallen leaves everywhere. 3.某些动词的过去分词已成为形容词，这类形容词多用来表示人物的心理特征或感情变化。常见的这类过去分词有：disappointed, moved, interested, surprised, shocked, puzzled, excited, frightened, worried, pleased。 The frightened boy turned around and ran away quickly.那个受惊的男孩转过身去,很快地跑开了。 From his excited look, I know he passed the examination.从他兴奋的表情中，我知道他通过了考试。 4.过去分词作定语，可以转化成相对应的定语从句。 Eg.She bought a dress made in France. 她买了一条法国制造的裙子。 = She bought a dress that was made in France. Eg.This is an organised trip . 这是一次有组织的旅行。 =This is a trip that was organised by ... V.过去分词用作宾补，用于“主语＋谓语＋宾语＋宾补”句式，说明宾语的性质或状态。宾语与过去分词之间为被动关系，即宾语是过去分词动作的承受者。 能够接过去分词作宾语补足语的动词主要有两类：一类是感官动词，另一类是使役动词。 1.感官动词：see,hear,feel,notice 等 When we got to school, we saw the door locked. 当我们到学校时，我们看见门锁着。 He found his house broken into when he got back home. 回到家他发现家被盗。 2.“使役”动词。如：have, make, get, keep等接过去分词作宾补时，表示 “致使某人/某物被....”。 He went to the hospital to have his eyes examined.他去医院检查了一下眼睛。 The foreigner tried to make himself understood, but failed.那个外国人试图让别人明白他的意思,但失败了。
