Ngu phap reported speech

Statements
If we want to say what other people said, thought or felt, we can use the direct and indirect speech (reported speech). The direct speech: "I like it," he said. "Irene is late," he thought. "I will pass the exam," she hoped. The reported speech: He said he liked it. He thought that Irene was late. She hoped she would pass the exam. The reported speech is typically introduced by verbs such as say, tell, admit, complain, explain, remind, reply, think, hope, offer, refuse etc. in the past tense. He said (that) he didn`t want it. She explained that she had been at the seaside.
If these verbs are in the past tense, we change the following: a) verb tenses and verb forms b) pronouns c) the adverbs of time and place
A) Verb tenses
We change the tenses in the following way:
Present - past "I never understand you," she told me. - She told me she never understood me. "We are doing exercises," he explained. - He explained that they were doing exercises.
Present perfect - past perfect "I have broken the window," he admitted. - He admitted that he had broken the window. "I have been waiting since the morning," he complained. - He complained that he had been waiting since the morning.
Past - past perfect "She went to Rome," I thought. - I thought that she had gone to Rome. "He was thinking of buying a new car," she said. - She said he had been thinking of buying a new car.
Will - conditional Will changes into the conditional. I will come on Sunday," he reminded me. - He reminded me that he would come on Sunday.
As you can see, both the past tense and the present perfect change into the past perfect.
