1. Earth looks like a big blue marble (玻璃球); from high above the Earth and from the moon, the planet gleams and shines.
    地球看上去就像一个巨大的蓝色玻璃球, 从高高的地球上空或从月球上望去，这颗行星熠熠生辉，闪闪发光。

2. Because the Moon has only an eightieth of the Earth´s mass,
    因为月球的重只有地球的1/8，

3. Because the gravity on the Moon´s surface is only a sixth of Earth´s (remember how easily the Apollo astronauts bounded along),
    由于月球表面的重力仅是地球表面的1/6 -- 还记得阿波罗飞船中的宇航员累松地跳跃 --

4. Watching the first man land on the moon, we beheld a sighy never seen before by man .
    看那踏上月球的第一人，我们看到了人类所未见的景象。

5. It requires 97 per cent less energy to travel the quarter of a million miles from the Moon to Earth-orbit than the 200 mile-journey from Earth´s surface into orbit!
    因此，从月球到地球的25万英里所消耗的能量要比从地球表面进入地球轨道的200英里所耗能量少97%。

6. When that side of the moon on which the sun is shining is facing us, we see a round shining circle — a full moon.
    当月亮接受阳光照射的一面面向我们时，我们看到的是个发亮的圆盘——满月。

7. When the moon is like this, we call it a quarter moon.
    这时的月亮我们称之为半月。

8. We call this a new moon.
    我们称之新月。

9. We see the change from new moon to quarter to full and back to new moon every twenty-eight days.
    我们每二十八天就能看到从新月到半月、到满月再回到新月的变化过程。

10. The moon goes round the earth.
    月球环绕地球运转.
