Hello， everyone！ I am your science teacher， Dr. Know. Today， let’s talk about the MOON（月球）！

The answer is： TRUE

Things are lighter（更輕的） on the moon， because the moon’s gravity（引力） is only 1/6 of the earth’s.

Do you know？

Sometimes（有時(shí)） the moon looks like a small boat， but sometimes it’s like a white sun. Do you know why？

月亮為什么有時(shí)彎有時(shí)圓呢？是天狗吃月亮，還是它會(huì)變魔術(shù)？

其實(shí)月亮本身并不會(huì)發(fā)光，只是把太陽(yáng)光反射過來(lái)而已。而且月亮圍繞地球運(yùn)轉(zhuǎn)，地球圍繞太陽(yáng)運(yùn)轉(zhuǎn)。當(dāng)?shù)厍驌踝×瞬糠痔?yáng)光時(shí)，我們就看到了不完整的月亮。月食的產(chǎn)生也是這個(gè)原因。

Fun Facts：

There’s no air（空氣）， no water and no living things（生物） on the moon.

In the day， the moon is very， very hot. But it is very cold at night.

Armstrong was the first man to walk on the moon.
