BADBBStep 3 Grammar and UsageAccording to the exercises, we know the relative pronouns are used as objects either after verbs or after prepositions. When they are used as the objects of prepositions, the position of the prepositions must be paid more attention to. The preposition usually follows the verb in spoken English. We can use who whom that or which and they are usually omitted in spoken English. If the preposition is used before the relative pronoun, which or whom can only be used while who or that mustnt be used. Besides , which or whom cant be omitted. That is preposition + whom/which. Please look at the screen.1. A. The person(who/whom/that) you should write to is Mr. Ball.B. The person to whom you should write is Mr. Ball.2. A. The games (which/that) he competed in were swimming and shootingB. The games in which he competed were swimming and shooting.T: But how to choose the proper prepositions is very important. We can choose them in three ways. First, we can find out which verb the preposition is used with in the clause. Second, we can find out which noun or pronoun the clause modifies. Third, we can find out the meaning of the clause. Ill give you some examples. Look at the screen ,please.1. A. Have you met the person about whom he was speaking?B. He is the man to whom you can turn for help.2. A. The farm on which we worked ten years ago isnt what it used to be.B. This is the tree under which we used to play games.3. A. The pen with which he is writing now was bought yesterday.B. The gas without which we can not live is called oxygen.T. Are you sure about that?Ss: Yes.T:OK. So much for my explanations. Please turn to page 28 and go through the introduction about preposition + which/whom.(Give the students several minutes to go through it. )T: Well, we have known this kind of attributive clause. Lets do Exercises A and B to consolidate it. I give you several minutes to do them. While doing, you can discuss with your partners.(Several minutes later, the teacher checks the answers)Suggested answers:A: l-c 2-d 3-b 4-a 5-e 6-h 7-f 8-gB: l-which 2-which 3-about 4-from 5-fromT: We have mastered the usages of relative pronouns. Next well learn the usages of the adverbs: where, when, why. We use where for place, when for time, why for reason. Relative adverbs not only introduce attributive clause, but also are used as adverbials in the clause. Please look at the sentences on the screen.1. The house where(=in which) we live is not big.2. Thats the hotel where (=at which) we stayed last year.3. Do you remember the day when (=on which) your sister graduated as a Master of Arts?4. 1988 is the year when (=in which) I was born.5. Do you know the reason why (= for which) he didnt come?T: The relative adverbs where when and why can be replaced by preposition 4- which. Here how to choose the proper prepositions depends on the noun or pronoun that the attributive clause modifies. Now please go through the introduct
