This note is only a reminder.It's _____.为什么选c不选d？more 和extra

Here’s a quick reminder to all of you when you get stuck in a moment. Yesterday I skipped breakfast because I got up late. Because of the busy school work, I forgot my lunch. When I was finally thinking of buying my lunch, a person in need asked me if I could spare him some cash, so I decided to give him some money.
Then later in the evening, I was heading home anxiously for dinner. However, I got a call from my mom. She said that she had to work late and wouldn’t be able to prepare dinner for me. Even though there was no food in the house, I told my mom not to worry as I would surely find myself something to eat.
While I was still processing this sudden set of changes in my food choice for the day, I passed a young man with a broad smile handing out samples of crackers(薄脆饼干) at the gate of a supermarket. He gave me a packet and then said, “How about you taking some more for school tomorrow?” In response to that, I returned a warm smile to him and opened up my bag. He gladly filled it. I was excited.
Whether you call it luck or fate, I just wanted to say that somewhere out there somebody came along carrying a pocket of hope in his heart and shared a piece of with me! Somebody out there will one day do the same for you.!
