I love eating persimmons (柿子). But people can't get them in summer. If people try them before the right time, they probably taste bad.
Mom was worried because my poor grades. She (wonder) whether I could go to high school or not. Summer came and hot sun shone all day. It made me feel (sleep). When I wanted to stop studying, Mom would shout, "If you give up now, you will regret it!" I sat well to study again.
Mom always said to me with a serious look on (she) face, "You won't get any fruit in autumn unless the persimmon tree (grow) in summer!" Although I didn't like it at that time, I (slow) understood mom's words. I took (act) and worked hard.
Several (month) later, I got into the key high school. It was autumn. I could see a few persimmon trees in the school yard. I realized that working hard might be bitter (苦的), its fruit was sweet.
