阅读下面短文，在空白处填入一个适当的词，或填入括号中所给单词的正确形式。
An old man went to India. When he got there, he saw some fruit for sale, but most of it was very cheap. The (cheap) thing has a basket of red fruit.
"How much per kilo?" the old man (ask).
"Two rupees (卢比)," the shopkeeper answered. Two rupees in India is almost nothing, the old man bought a whole kilogram and started eating it.
However, as soon as he started eating, his mouth began (burn), his eyes began to water, and his whole face became as red the fruit. As he coughed and struggled to breathe, he jumped up and , screaming: "Ah! Ah! Ah!"
And yet he continued to eat the fruit. Some people who were looking at him shook their (head) and said, "You are crazy! Those are chili peppers (辣椒)!You can't just eat them by the handful!"
The old man said to (he),"I paid for them, so I must eat them."
This old man seemed pretty stupid. But are we so much smarter? All of us have (spend) money and time on something-maybe a relationship, or a business, or a job-and sometimes, even if we know there's no hope that things will change, we still continue with it.
What we can learn the old man is this: if you've lost a lot over something that doesn't work, let it go and move on. It's better than continuing to lose.
