“啊！不要啊！快离我远一点，救命啊！”一声声尖叫从XX作文班中传出，到底发生了什么？原来我们正在玩“针扎气球”的游戏。
Ah! Don't! Stay away from me, help! "Screams came from the XX composition class. What exactly happened? We were originally playing the game of "Needle Piercing Balloon".
今天星期六，我又来到了熟悉的XX作文班，我正坐在座位上思考今天会有什么惊喜时，余老师神神秘秘地走了进来。余老师拿出了一个气球，不知道要干什么。我心想：这“狡猾”的余老师今天又要干什么？他的葫芦里到底卖的什么药？接下来余老师让我的同桌来吹气球，只见瘦弱的同桌鼓足了勇气，好像用尽了吃奶的力气，才把气球缓缓吹起。
Today Saturday, I came to the familiar XX composition class again. I was sitting in my seat thinking about what surprises I would have today when Teacher Yu mysteriously walked in. Teacher Yu took out a balloon, unsure of what to do. I thought to myself: What is this' cunning 'Teacher Yu going to do today? What medicine is sold in his gourd? Next, Teacher Yu asked my desk mate to blow up the balloon. I saw the thin and weak desk mate muster up the courage, as if he had exhausted all his strength to slowly inflate the balloon.
余老师又拿出了一根明晃晃的、好像散发着寒光的银针，微笑着说：“今天，我们来玩一个游戏——给气球打针。”顿时，全班同学都被吓出了一声声尖叫，我也十分害怕，因为我十分害怕爆炸声，连小摔炮都不敢玩。
Teacher Yu took out another shiny silver needle that seemed to emit a cold light and smiled, saying, "Today, let's play a game - give a balloon an injection." Suddenly, the whole class was scared and screamed, and I was also very scared because I was very afraid of the explosion sound. I didn't even dare to play with the small cannon.
游戏开始了，老师先叫来了李同学给气球“打针”。他刚开始显得十分镇定，我知道他是装的，因为我看见他的手开始发抖，气球也抖了起来。现在，全班鸦雀无声，有的捂着眼睛，有的捂着耳朵，有的胆小的已经躲到了桌子下面……他扎了下去，随着“砰”的一声响，气球炸成了一地碎片。
The game started, and the teacher first called Li to give the balloon an injection. At first, he appeared very calm, and I knew he was pretending because I saw his hands starting to tremble and the balloons also shaking. Now, the whole class is silent, some covering their eyes, some covering their ears, and some timidly hiding under the table... He plunged down, and with a loud bang, the balloon exploded into pieces on the ground.
接下来，余老师又拿出了一个气球吹了起来，他左手拿着明晃晃的针，右手举着气球，朝着气球的“屁股”扎了下去。我们都在这一瞬间捂上了耳朵。可是过了一会儿，居然没有听到响声，我好奇地睁开眼睛，只见余老师拿着针正旋转着，那根针一点一点穿过了气球的皮肤，真是难以置信，这时针已经穿进去了一大半，针尾在摇晃，气球还是安然无恙，难道老师造假了？
Next, Teacher Yu took out another balloon and blew it up. He held a shiny needle in his left hand and held the balloon in his right hand, stabbing it towards its "butt". We all covered our ears at this moment. But after a while, I didn't hear any sound. Curiously, I opened my eyes and saw Teacher Yu holding a needle and spinning it. The needle slowly penetrated the skin of the balloon, which was unbelievable. The hour hand had already penetrated half of it, and the tail of the needle was shaking. The balloon was still safe and sound. Could it be that the teacher had fabricated it?
最后，余老师准备把针拔出来，我们猜：气球一定会瞬间干瘪或者爆炸。可余老师缓缓地将针拔了出来，气球既没有破也没有干瘪，真是不敢相信啊！
Finally, Teacher Yu prepared to pull out the needle, and we guessed that the balloon would instantly deflate or explode. Teacher Ke Yu slowly pulled out the needle, and the balloon was neither broken nor deflated. I can't believe it!
“老师不会造假了吧？””老师会不会没把针扎进去？”一阵阵议论声响了起来。而余老师十分耐心地对我们说：“气球的尾部较厚，而针尖又细又长，在胶皮的缓冲作用下，针扎气球并不会爆炸；而橡胶的回弹力会在拔针时迅速堵住针孔，气球不会瞬间漏气。”
Did the teacher not insert the needle? ”Waves of discussion erupted. Teacher Yu patiently told us, "The tail of the balloon is thick, and the needle tip is thin and long. With the buffering effect of the rubber, the needle piercing the balloon will not explode; and the rebound force of the rubber will quickly block the needle hole when the needle is pulled out, so the balloon will not leak instantly
这时，我们才恍然大悟。这真是一次惊险的体验，又是一次开心的体验。
At this moment, we suddenly realized. This is truly a thrilling experience, yet another joyful experience.
