Suggested answer:
Direct speech reprts the exact wrds f the speaker. Indirect speech reprts what a speaker said in ur wn wrds. There are sme grammatical differences between direct and indirect speeches. If we want t change direct speech int indirect speech, we will change tenses, prnuns, and ther wrds when necessary. First, if a verb in qutatin marks is in present tense, change t crrespnding past tense; if a verb is in simple past tense, change t past perfect tense. Secnd, persnal prnunces change accrding t the persn f the bject f the reprting verb. Third, adverbs that shw nearness in direct speech are usually changed int wrds that shw distance in indirect speech. Fr example, nw changes t then; tday changes t that day; here changes t there.
