S3 Jason got accepted as a member of the university’s soccer team T Right.I think everyone has grasped the usage of “get”.Next,let’s look at one more type of the passive voice. T An infinitive can take a passive form when its logical subject is actually the receiver of an action.Look at the following examples. .I was happy to be invited to the lecture .The meeting had to be put off owing to the wet ground T Here the logical subjects are the receivers of the verbs.In the first sentence,the logical subject is “I”while in fact “I” is the receiver of “put off”,and in the second one,it is “the meeting” .The problem remained to be solved .These flowers need to be watered T Now,we have learned the type of “to be done”.you have three minutes to drill T In addition to the two types,we also will learn another one. T A “V+ING”phrase can take a passive form when its logical subject is actually the receiver of an action. .I like the film being played at the theatre .She hates being interruted when speaking T In the first sentence,the logical subject of “being played” is “I’,and in the second one,it is “she”. T Well,let’s look at the following examples .The nurse is taking good care of the baby T If you want to emphasize “the baby”,the sentence should be:The baby is being taken care of by the nurse.Howerer, “the nurse”is often generally omited. .We are looking forward to the superstar to attend the ceremony. .The superstar is being looked forward to attend the ceremony . T This is called the passive voice of multi-word verbs. When an active voice with a multi—word is changed to a passive voice,the multi—word shall be put together,not divided or omitted Step4 Consolidation T Well,enough of that.Now let’s see whether we can use them freely or not.Now,look at some exercises for you. Please fill in the blanks with proper formation of given words .The driver who got ____ caused the accident .The young trees require _________. .In the fire,no one escaped from________ .We should prevent the river from_______ by the chemical factory. .The books are said ________ again next month SUGGESTED ANSWERS: Drunk; to be watered; being killed; being polluted; to be published Step5 Summary and homework T In this section we have learned about the passive voice .From the contents above,we learn four types of the passive voice,which include “be done”, “get done”, “to be done” and “being done”.Then we spent quite much time in knowing usage of them.So today’s homework is to go through this after class and try to get familiar with them Step 6 The design of the writing on the blackboard UNIT3 THE COMPUTER SECTION3 GRAMMAR Be done Get done .
