我们来讲讲月球吧

All About the Moon: Astronomy and Space for Kids - FreeSchool

欢迎来到《免费学校》!
You’re watching FreeSchool!
神秘而美丽 清澈而平静的月亮
Beautiful and mysterious,peaceful and serene
是夜空中最耀眼的物体
the moon is the brightest object in the night sky
木星和土星都至少有60颗卫星
Jupiter and Saturn have more than sixty moons each.
海王星则有13颗
Neptune has thirteen moons
就连火星都有两颗卫星
Even mars has two moons
但是我们的地球只有一颗卫星
But the Earth, our planet, only has one moon
它是地球在太空中最近的邻居
our nearest neighbor in space.
虽说相比其它星球
Even though the moon is close to us
月球离我们很近
when compared to other planets
但其实距离还是很远的
it is still very, very far away
月球与我们相距239000英里
The moon is about 239 thousand miles
或者说384000公里
or 384 thousand kilometers away
你得绕地球
You would have to travel all the way around the Earth
走九圈半
nine and a half times
才能走完
to go the same distance as the space
同样的距离
between the Earth and the Moon
月球比地球小的多
The moon is much smaller than the Earth
如果地球是空心的
if the earth was hollow
里面可以放下大约50个月球
about fifty moons could fit inside
由于月球比地球小很多
Because it is so much smaller than the Earth
它的重力也弱很多
the moon’s gravity is much weaker
这意味着 如果你去了月球
This means that if you were to visitthe moon
你的重量会比地球上的小
you would weigh much less than you doon earth
重量大约是地球上的六分之一
only about 1/6th of your current weight
也就是说月球上的长颈鹿
That means that if a giraffe was on the moon
差不多和地球上的老虎一样重
it would only weigh as much as atiger on earth!
尽管晚上月亮十分明亮
Although we can see it shining brightly atnight
但它本身并不发光
the moon does not have any light of its own
我们所看到的月光 其实是
Instead, the light of the moon isreally
太阳光照到月球表面后
reflected light from the sun
反射出的光线
that bounces off of the rocky, dusty surface of the moon
因而在地球上可以看见
So that we can see it from Earth.
由于月球绕着地球转
Because of the way that the moon orbits the earth,
有时太阳光就会照到不同的地方
sometimes the sun lights up different parts of it.
这使得月球前后两夜看起来变了模样
This makes the moon appear to change its shapefrom one night to the next
这些不同的形状被称为月相
These different shapes of the moon are called its phases
月球大概需要29天显现所有的月相
It takes about 29 days for the moon to go through all of its phases
然后再循环这个过程
and begin them again
月亮如此地大 如此地明亮 如此地近
Because it is so big, and bright, and closeto us
它总是吸引着心怀好奇的人的注意
the moon has always attracted the attention of curious people
到20世纪中期
But in the mid-20th century
人类对太空更加来了兴致
people around the world began to be more interested in space
人类史上第一次
For the first time
发射火箭 摆脱地球重力 穿过大气层
humans launchedrockets that were able toescape earth’s gravity and atmosphere
探索外太空
and explore what lay beyond.
历经了大量的研发和测试
After a lot of work, and many tests,
人类终于首次造访了月球
humans were able to visit the moonfor the first time.
1969年7月20日
On July 20, 1969,
美国宇航员乘坐阿波罗11号登陆月球
the astronauts of America’s Apollo 11 missionlanded on the moon.
7月21日
On July 21,
尼尔·阿姆斯特朗成为首位踏上月球的人
Neil Armstrong became the first personto step upon the moon’s surface.
月球上没有大气层
The moon has no atmosphere,
也就是说 没有空气可供呼吸
which means there was no air for them to breathe.
月球上的温度也很极端
The moon also has extreme temperatures
阳光照射滚烫至极 阴暗之地则犹如寒冰
boiling hot in the sunand freezing cold in the shadows.
因此 需要特殊衣服和装置来保护宇航员
For this reason, the astronauts needed specialsuits and equipment to protect them on the moon
使他们能够呼吸 并处于适宜的温度
to keep them the right temperature andallow them to breathe.
40多年了 没人再造访月球
No one has visited the moon for more than40 years,
但月球表面 宇航员走过的脚印依然存在
but the footprints made by the astronauts who walked on its surface are still there.
因为月球上没有水 没有风
That is because there is no wind or water on the moon
不会让脚印消失
to wash the footprints away.
除非某颗陨石砸中了月球 将其损坏
Unless a meteorite hits the moon and smashes them,
脚印会存留上百甚至几千年之久
those footprints might last for hundreds oreven thousands of years.
希望你能喜欢今天所学的有关月球知识

goodbye till next time!
