3 Several types of passive voice

A sentence with two objects can usually take the object as the subject respectively, resulting in two passive voices. However, sentences with objects and object complements can only create a passive voice. 1 passive voice formed by transitive verbs He was held the interesting story by me. The interesting story was held to him by me. I told him that interesting story. 1. For the passive voice of a sentence with an object, see the example < 2. Active voice becomes passive voice > on page 167. The passive voice of a sentence with two objects Verbs such as give, teach… are often followed by two objects, which can also be called double objects. Usually, this sentence can be changed into two passive voices with "person" as the subject and "thing" as the subject. Tom gave me a present. Tom gave me a present. I was given a present by Tom. (with person "I" as the subject) A present was given(to)me by Tom. (with object "present" as the subject) He teaches us English. We are proud English by him. English is proud us by him. He bought me a book. He bought me a book. I was bought a book(by him). This sentence is grammatically correct, but it is awkward in practical application, so it is generally not used) A book was bought for me(by him). (Taking things as the subject) 3. Verbs such as call and make in the passive voice of sentences with object complements often have object complements, and in the passive voice, the position of object complements remains unchanged. Pay attention to all verbs with infinitive object complements, even sensory verbs such as feel, see, hear, watch, look at, listen to and causative verbs such as let, make, have and help, and add to them when they become passive voices. See chapter 14. 2 passive voice formed by intransitive verb+preposition or adverb Many trees are cut down by workers. Intransitive verbs can't follow the object, of course, there is no passive voice, but some intransitive verbs, followed by a preposition or adverb (that is, forming a so-called verb phrase), have the same function as a transitive verb, so don't remove the preposition or adverb when it becomes passive voice. She looks after them. She takes care of them. (○) They are looked after by her. (×) They are looked by her. We laughed at him. He was laughed at(by us). Must recite! Passive voice of verb phrases take care of care →be taken care ofcut down → Be cut down and laugh at → Be laughed at and look after care →be looked after! Verb phrases in passive voice The following phrases are in the form of passive voice, and there is no need to add "by". Be covered with be surprised at be known to be interested in be made of(from) The person must be taken care of by his son. When a sentence containing modal verbs becomes passive, just add a be verb after the modal verbs, and the sentence pattern is as follows: affirmative sentence: subject+modal verbs (Can, may, must)+be (always prototype)+past participle ~. negative sentence: subject+modal verbs +not +be+past participle ~. interrogative sentence: modal verbs (can) Note that when the sentence pattern of "be going to+verb prototype" becomes passive, we regard be going to as a word, just like the modal verb can, so its passive voice should be "be going to be+past participle". He is going to make it. → It is going to be made (by him). We can change water into ice. We can turn water into ice. Water can be changed into ice. Water can be turned into ice. You must not take out any books. You can't take any books. Any books mustn't be taken out by you.Can you use it？ Will you use it?
