今天，我到小记者班，老师说：“咱们做个实验”。老师拿出一个杯子，把杯子倒满了水，老师问我们：“要是把一张纸放到这个杯子口上，倒过来会怎么样呢？”同学们七嘴八舌，议论纷纷，你一言我一语的说者，有的说纸不会湿，有的说纸会湿，还有的说水不会洒出来。
Today, I went to the reporter class. The teacher said, "let's do an experiment.". The teacher took out a cup and filled it with water. The teacher asked us, "what if I put a piece of paper on the mouth of this cup and pour it over?" The students are full of talk. Some of you say that paper will not be wet, some say that paper will be wet, and others say that water will not spill out.
开始实验了，老师快速的把杯子倒过来，这时教室里静悄悄的连针掉到地上的响声都能听见，有的同学的眼睛眨也不眨。开始实验了，我第一个上台，单失败了，后来的两位同学都成功了。
At the beginning of the experiment, the teacher quickly turned the cup over. At this time, the classroom was quiet, even the sound of the needle falling to the ground could be heard, and some students' eyes did not blink. I started the experiment. I was the first one on stage, but I failed. Later, both of my classmates succeeded.
我们想知道是什么原因，老师告诉我们是大气压力。这个实验真有趣！
We want to know what the reason is. The teacher told us it was atmospheric pressure. What an interesting experiment!
