111 Period 5 Grammar The General Idea of This Period This is the fifth period, which will center on the grammar: using the past participle as the attribute and the predicative.At the beginning of this period, the teacher should give the students some time to go over what they learned in the last period. Later the teacher had better present some sentences containing the past participle used as the attribute and the predicative on purpose by asking the students to do some exercises.Get the students to find all the sentences containing the past participle in the two passages.After finding them, the teacher can ask the students to analyze them and understand the function of the past participle in those sentences.After that the teacher should give the students clear explanations about the usage of the grammar. After mastering the rules of the past participle, the students should be given more exercises to consolidate what they learn.The teacher should arrange some activities carefully and creatively. First let them do some simple exercises.For example, combine the two sentences using the past participle as the attribute and the predicative.Then ask them to make some sentences using the past participle. Besides that, the teacher should help the students to review the other usages of the past participle.In the end, let them write a passage using the past participle properly. Apart from the usage of the past participle, the teacher had better make the students understand the differences between the past participle and the present participle.In order to have the students master it, the teacher should choose some exercises to supply the students with some problems to deal with.By doing and practicing more, the students may master the grammar. Teaching Important Point To learn about the past participle used as the attribute and the predicative. Teaching Difficulty To know the differences between the past participle and the present participle. Teaching Aids Multi-media classroom and other normal teaching tools. Three Dimensional Teaching Aims Knowledge Aim To learn about the past participle used as the attribute and the predicative.  Ability Aim To use the past participle used as the attribute and the predictive freely and properly in speaking and writing. Emotional Aims Encourage the students learn more about the grammar. Help the students to form the good habit in learning. Encourage the students to do more exercises to consolidate their knowledge. Teaching Procedure Step 1 Greeting T: Hello, my friends. Ss: Hello, Miss... Step 2 Revision T: Do you still remember what you learned in this unit?Would you please say something about the great scientists we learned in this unit.First please something about John Snow. S: John snow, a well-known doctor in London, defeated cholera. S: He got interested in two theories explaining how cholera killed people. S: John Snow gathered the information and marked it on a map where all the dead people had lived. S: He discovered that many of the deaths were near the water.It seemed the water was to blame. Ss: ... T: You really did a very good job.Now, let’s say something about Nicolaus Copernicus. S1: Nicolaus Copernicus believed that the earth is not the centre of the solar system.But at that time people all believed God had made the world and for that reason the earth was special and must be the centre of the solar system. S2: In 1514 he showed his theory privately to his friends and explained his theory. S3: He was very cautious because he did not want to be attacked by the Christian church. S4: He published his theory as he lay dying in 1543. S5: His theory was rejected by the Christian Church. Step 3 Presentation T: Today we will learn the grammar—past participle used as the attribute and the predicative. First look at your text on Page 4, part I.Look at the following sentences where the past participles are used. T: In this sentence the past participle is used as an attribute phrase.Terrified people means people who were terrified.Now please find two more examples from the reading passages with past participles used as the attribute.You are allowed to find as many sentences as possible in two minutes. (Two minutes later, ask the students to report what they have found.) S1: From the stomach the disease attacked the body quickly and soon the affected person was dead. S2: Immediately John Snow told the astonished people in Broad Street to remove the handle from the water pump so it could not be used. S3: John Snow suggested that the source of all water supplies be examined and new methods of dealing with polluted water be found. S4: He placed a fixed sun at the centre of the solar system. T: Good.You just found all the sentences containing the past participles used as the attributes.Besides using as the attribute, the past participles can also be used as the predicative.Can you find the sentences with past participles used as the predicative?Finish it in two minutes. (Two minutes later, let the students read these sentences with past participles as the predicative.) S1: Neither its cause, nor its cure was understood. S2: He knew it would never be controlled until its cause was found. S3: He got interested in two theories explaining how cholera killed people. S4: They were given free beer and so had not drunk the water from the Broad Street pump. S5: He found that it came from the river, which had been polluted by the dirty water from London. S6: Immediately John Snow told the astonished people in Broad Street to remove the handle from the water pump so it could not be used. ... Step 4 Practising T: From the sentences mentioned just now, what do you know about the usage of past participles as the attribute and the predicative? S: We use past participles as attributes when we want to join two clauses together. T: Yes, very good.Now let’s look at the screen and finish the exercises quickly. Past Participle as the Attribute Past Participle as the Predicative 1.terrified people 2.reserved seats 3.polluted water 4.a crowded room 5.a pleased winner 6. 7. 8. 9. 10. 1. 2. 3. 4. 5. 6.children who look astonished 7.a vase that is broken 8.a door that is closed 9.the audience who feel tired 10.an animal that is trapped Suggested answers: 1.people who are terrified　2.seats which are reserved　3.water which is polluted　4.a room which is crowded　5.a winner who is pleased　6.astonished children　7.a broken vase　8.a closed door　9.the tired audience　10.a trapped animal 過去分詞作定語, 在語態(tài)上, 表被動; 在時間上, 表示動作已經(jīng)發(fā)生或完成, 與它所修飾的名詞有邏輯上的動賓關(guān)系。過去分詞作定語時, 所修飾的名詞在邏輯上相當(dāng)于被動句中的主語, 過去分詞相當(dāng)于謂語。如:  The destroyed house will be rebuilt next year. 這種情況下的過去分詞為及物動詞的過去分詞。 不及物動詞的過去分詞很少能單獨作前置定語, 少數(shù)表示狀態(tài)改變或位置轉(zhuǎn)移的動詞的過去分詞可前置, 僅表示時間的完成, 無被動意義。而現(xiàn)在分詞表示動作正在進行。如:  falling leaves正在下落的樹葉　a developing country發(fā)展中國家　the boiling water沸水 fallen leaves落葉　a developed country發(fā)達國家　the boiled water(涼）開水 T: Besides this, the past participle can be put after the noun to modify the noun form, for example, The famous writer’s play, mentioned in one of my books, was published in 1963. Do you understand the sentence? S: The famous writer’s play, which was mentioned in one of my books, was published in 1963. T: Yes, very good.In this sentence we can get two pieces of information.A: The famous writer’s play was published in 1963.　B: The play was mentioned in one of my books.Now, let’s do some exercises to combine two sentences together using past participle as the attribute. 1.This is one of the questions.　It was discussed at the meeting yesterday. S: It is one of the questions discussed at the meeting yesterday. T: His letter was addressed to the wrong number.It reached me late. S: His letter, addressed to the wrong number, reached me late. T: The students didn’t know how to answer it.They were surprised at the way the question was put. S: The students, surprised at the way the question was put, didn’t know how to answer it. T: The audience all voiced support for the suggestion.They were moved by his speech. S: The audience, moved by his speech, all voiced support for his suggestion. T: Basketball is now an interesting sport.It was first played in the USA. S: Basketball, first played in the USA, is now an interesting sport. T: Well done. 注意下面過去分詞作定語的幾種情況:  1.單個的過去分詞作定語一般放在被修飾的名詞之前。如: the terrified people, the polluted water, the astonished people。 單個分詞也可以作后置定語, 用以強調(diào)動作。如:  They decided to change the material used.他們決定更換使用的材料。 2.過去分詞短語作定語要放在被修飾的名詞后面, 作后置定語, 其作用相當(dāng)于一個定語從句。如: The man chosen mayor of the city received a Doctor’s Degree of Engineering. 3.如被修飾的詞是 something, anything, everything, nothing 等, 分詞放在被修飾詞的后面。如: Do you have anything unfinished? 4.單個過去分詞前加一名詞或副詞, 常用連字符將它們連接起來構(gòu)成一個復(fù)合形容詞, 放 在其修飾的名詞前, 作前置定語。分詞前加的名詞表示分詞的動作或行為主體, 所加的副詞表示方式、時間、程度、性質(zhì)等意義。如: a newly-born baby, a well-known doctor。 T: Now let’s come to the past participle used as the predicative.Generally speaking the past participle used as the predicative shows the state the subject remains.(過去分詞作表語表示主語所處的狀態(tài)。) eg: I was surprised to find that such great changes had taken place in the college. Now look at the screen.Finish the exercises quickly. 1.He got__________ about losing the money. 2.Why do you always look so __________?Do you sleep well these days? 3.I was__________ with the film I saw last night.I had expected it to be better. 4.Everybody was__________ to hear the death of the famous film star. 5.The children are really__________ about going to the zoo. 6.His wound became__________ with a new virus. Suggested answers: 1.worried　2.tired　3.disappointed　4.astonished　5.excited　6.infected T: Well done.
