Answer:
There was a king in China who used to spend hours in his uniform, parading before a mirror in his room. He would remain secluded in his palace, admiring himself while his subjects starved to death, and his kingdom went to ruin. One night, a courtier gathered a group of palace attendants and, while the king slept, cut a window on the wall where the king's mirror had hung. The next morning, when the king dressed himself in his sparkly medals, he walked to where the mirror had been and saw to his amazement the unending procession of his people passing on the street. He saw starving children reaching into garbage cans for crusts. He saw sick and maimed men and women. He tore off his medals,called for simple clothes, and went out to mingle (mingle ) with the people. His whole outlook on life changed when he stopped looking into mirror at only himself.
Step-by-step explanation:
0. to spend → completes the meaning of "used", as in the expression "used to do something."
1. parading → needs -ing to indicate it's completing the meaning of the verb "spend", as in "he used to spend hours parading before a mirror."
2. starved → we need the verb to be in the past form here, since the text is narrated in the past.
3. attendants → this sentence refers to the people who worked at the palace, that is, its attendants.
4. sparkly → we need an adjective to modify the noun "medals".
5. amazement → it is a common expression, "to one's amazement".
6. maimed → we need an adjective to modify the nouns "men and women".
7. tore → the verb is conjugated in the past form.
8. to mingle → we need to add "to" before the verb to indicate the king's intention.
