A Visit to a Planetarium | 参观天文馆

Yesterday, Ms. Kim’s fourth-grade class visited a planetarium. It was a big round room with rows of seats in a circle and a dome overhead. While the class was getting seated, a student asked, “Where are the plants?”

 

Ms. Kim said, “The word planetarium comes from planet, not plant. We’re here to learn about planets and stars.” In the center of the room was a large sphere. It was a metal ball that was full of small holes. An amiable man walked in with a smile and started the program, which was called a sky show. He said that the dome was a big screen and the sphere was a star projector. A light in the projector shines through the holes and makes images of stars on the screen.

 

The room began to darken slowly, as if the Sun were going down. Finally it was very dark and the stars came out. “This is what the sky will look like at ten o’clock tonight,” the man said. The students saw the planet Mars, which glowed red. They saw the stars of the Big Dipper and Orion. They learned that because Earth rotates, the stars appear to move across the sky during the night. Then they learned that because of the way Earth orbits the Sun, people see different stars at different times of the year. When the show was over, some students said they were going to look at the stars that night.

 

 

 

昨天,金小姐的四年级的班级参观了天文馆,天文馆就是一个有很多座位排成的圆形房子,并有一个圆形屋顶。整个班级的同学都做好了以后,一个同学就问:“有植物?”

 

金小姐说:“天文馆一次来源于星球,而不是植物。 在这里我们可以认识了解星球和星星。在房间的中心有一个大球,打球时一个有很多空的金属球。一个亲切的人面带微笑走进来,开始了这个叫做“天空秀”的节目。他介绍说圆屋顶是一个非常大的屏幕,圆球是星星发射仪,投影仪中的一束束光通过空道在屏幕上形成星星的影像。

 

房间慢慢地变暗,好像太阳下山了,最后变得很暗,星星就出来了“就是今晚十点天空的样子”那个人说道。同学们看到了发红的火星。同时看到了北斗星和猎户座。他们了解到地区旋转导致星星晚上的转动。由于地球围绕着太阳公转,人们会在一年不同的时间看到不同的星星。当这个节目结束时,一些同学说打算晚上观察星星。
