In Grade Six, because of my poor grades, my parents were  18  that I wouldn't be able to get into an excellent middle school. They  19  me to study harder, but I didn't really understand why they were so anxious.

Summer came, and I studied hard. The hot weather made me   20   and I couldn't focus on my textbooks. But every time I wanted to stop  21  , Mom would shout, "Hey, you! Think about your  22  . If you don't work hard, you'll regret (后悔) it!" I had to sit back down again and return to my textbooks. But all I  23  was playing with my friends and eating persimmons.

Walking in my new school, I could see quite a few persimmon trees. The fruit was so red that it looked as if it was on fire. Suddenly, I  28   that working hard may be bitter but its fruit is sweet.

My mom was right: If a persimmon tree doesn't grow  29  summer, it can't bear fruit in autumn. I smiled.

I had grown through the summer  30  now it was autumn.

I tasted my success and enjoyed the fruits of my labors!
