Answer:
The blanks in the paragraph can be filled by using indirect narration of son and father's direct speeches.
Explanation:
Father asked his son (a) where he was going. The son replied (b) that he was going to his friend’s house. The father further questioned
(c) if he had completed his homework. The son said that he would do it when (d) he would come back. The father disapproved of the son’s way to answer.
We have to make some changes in the reporting (outside inverted commas) and reported speech (inside the inverted commas).
For the purpose of simplicity, let's learn about rules relevant to only this task (paragraph).
Part A
i) Since the reported speech (inside inverted commas) is a question, we use <em>asked </em>instead of <em>said.</em>
ii) Since the person (subject) in the reported speech is second person <em>(you) </em>it will be changed according to object in the reporting speech (<em>son</em>). Hence <em>you</em> is changed to <em>he.</em>
iii) Since tense of the reported speech is past (we assume it so from the rest of the paragraph, and it usually is past indefinite), we will change the tense (present continuous) of the reported part and make it past (continuous) tense.<em> (are going </em>to<em> was going).</em>
iv) Since the statement is no more interrogative, question mark (?) at the end is replaced by full stop (.).
Part B:
i) Since the reported speech (inside inverted commas) is a reply to a question, we <em>change said to replied.</em>
ii) Since the person (subject) in the reported speech is first person <em>(I) </em>it will be changed according to subject in the reporting speech (<em>son</em>). Hence <em>I </em>is changed to <em>he.</em>
iii) Since tense of the reporting speech is past, we will change the tense (present continuous) of the reported part and make it past (continuous) tense.<em> (am going </em>to<em> was going).</em>
Part C:
i) Since the reported speech (inside inverted commas) is a Yes/No question, we <em>use if/whether </em>before the subject of reported speech in indirect speech.
ii) Since the person (subject) in the reported speech is second person <em>(you) </em>it will be changed according to object in the reporting speech (<em>son</em>). Hence <em>you</em> is changed to <em>he.</em>
iii) Since tense of the reporting speech is past, we will change the tense present perfect of the reported part and make it past perfect) tense.<em> (have done </em>to<em> had done).</em>
iv) Since the statement is no more interrogative, question mark (?) at the end is replaced by full stop (.).
Part D:
i) Since the person (subject) in the reported speech is first person <em>(I) </em>it will be changed according to subject in the reporting speech (<em>son</em>). Hence <em>I </em>is changed to <em>he.</em>
iii) Since tense of the reporting speech is past, we change <em>will</em> to <em>would </em>in reported speech.
Some common rules for changing persons/pronouns of reported speech when changing direct speech into indirect speech are;
Change first person of reported speech according to Subject or reporting speech.
Change second person of reported speech according to Object of reporting speech.
No change in third person of reported speech.
Here we get an acronym SON (first person according to Subject, second person according to Object, No change for third person).
