下面的内容形象地概括了我国农村的“昨天”“今天”“明天”：
“昨天”：七沟八梁一面坡，农民住在草窝窝；豌豆红薯度苦日；无电无路打黑摸；儿童有眼难识字，村里光棍聚成坨。
“今天”：绿草如阴树满坡，田闽地头是林果；层层新房排排建，村民争听科技课；干部齐心奔小康，共创文明新生活。
“明天”：吃油穿绸住高楼，农民也要踢足球；手机打到华盛顿，驾着小车外国游；英明领导铺新路，幸福美景织锦绣。

      This summer I will leave the junior high school where I have been for three years. I am generally considered to be a careful and polite boy now. However, five years ago, I was a little bit bossy(专横的). I often fought with other boys and sometimes I even fought with my elder sister. When I saw Superman on TV for the first time, I dreamed of being a superman one day.
    One P.E. class, I called up all of my friends to get together in our classroom. “Can anybody jump out of the window?” I asked them. After hearing this, all my friends kept silent. “I know you are all chickens,” I said. “Can you?” one of my friends asked me. “Sure!” I answered. “If I do it, I will get all the toys that you have. If I fail, you will get all of my toys, OK?” They said, “OK!”
Then I went up to the window of the second floor. I took a deep breath and then jumped down, stretching out my arms just like Superman. Then I hit the ground.
     When I opened my eyes, I found myself lying in the hospital. I was taken to the hospital because my arms were badly hurt. Later, I heard that my P.E. teacher nearly lost his job for this, but I never received the serious punishment I feared.
