17 Curved Moon 弯弯的月亮 Share what we have observed about the changes in the moon. 交流我们观察到的月亮的变化情况。 This is what I have observed. 这是我观察到的。 I noticed that the moon sometimes looks like a disk and sometimes like a sickle. 我发现月亮有时像圆盘，有时像镰刀。 I found ...... 我发现…… When the Moon is viewed from Earth, it is sometimes full and sometimes short. 从地球看月球，月球有时圆，有时缺。 The shape of the shiny part of the Moon's surface that people see is called the phases of the Moon. 人们所看到的月球表面发亮部分的形状叫月相。 How are the phases of the Moon formed? 月相是怎样形成的？ The Moon is a satellite of the Earth. 月球是地球的卫星。 It revolves around the Earth from west to east, and one week of its revolution is about one month in the lunar calendar. 它自西向东围绕地球公转，公转一周的时间大约是农历的一个月。 The moon itself does not emit light, but reflects the sun's rays to make it shine. 月球本身不发光，靠反射太阳光才发亮。 While the Moon revolves around the Earth, the Earth carries the Moon around the Sun. 月球围绕地球转动的同时，地球又带着月球绕太阳转。 As a result, the side of the Moon that is illuminated by the Sun will sometimes face the Earth, sometimes turn its back to the Earth, and sometimes partially face the Earth. This is how the moon phase changes are created. 因此，月球被太阳照亮的一面就会有时面向地球，有时背向地球，有时部分向着地球。 Make a card with the moon phases for one month. 月相变化就是这样产生的。 Make a month's worth of moon phase cards. 做出一个月的月相卡片。 Continue to collect information on the Moon's relationship with the Earth, humans, flora and fauna. 继续搜集月球与地球、人类、动植物关系的资料。 |
