| 1. | Mr wu will give us a the earth and the moon
17吴先生将做个关于地球和月球的报告 |
| 2. | We ' ve been all the way to the moon and back , but we have trouble crossing the street to meet the new neibor
我们能够往返于地球和月球之间,但我们却不乐于穿过马路向新邻居问好 |
| 3. | By the time the two worlds had settled back down and begun drifting apart , their compositions would have been virtually identical
到地球和月球分离的时候，它们的物质成分已经差不多了。 |
| 4. | Since the distance between the moon and the earth is not constant , the angular size of the moon can have a small variation
由于地球和月球的距离并不固定，所以在地球看来，月球的角大小亦会出现变化。 |
| 5. | By repeatedly measuring the distance between them , scientists can calculate the orbits of the earth and the moon around the sun relative to each other
通过反复测量他们之间的距离，科学家们可以计算出地球和月球相对彼此，围绕太阳公转的轨道。 |
| 6. | According to general relativity , because the earth and the moon orbit the sun , they should “ fall ” towards it at the same rate , in the same way as galileo ' s balls fell to the ground
根据广义相对论，因为地球和月球围绕太阳公转，所以他们将会以同样的速度向太阳“坠落” ，正如伽利略的球体落向地面。 |
| 7. | If the earth was not there , the moon would travel in a straight line , that is , fly away . the earth and the moon attract each other , so the moon falls to the earth , just like a pen does
由于地球和月球互相吸引，月球便向地球靠拢，月球不断向地球方向落下，而落下的距离刚好和月球飞离地球的距离抵销，结果月球便能够以接近圆形的轨道绕著地球运行。 |
| 8. | Ilmenite is an iron titanium ore that earth and the moon have in common . mls - 1a is made from billion - year - old basalt found on the north shore of lake superior and mixed with glass particles that simulate the composition of the lunar soil
钛铁矿在地球和月球均普遍存在，而mls - la是仿照月球土壤成份把苏必略湖北岸数以亿年的玄武岩和玻璃颗粒混合而成。 |
| 9. | Other exhibits examine the sun - earth - moon orbital relationships and the causes of solar and lunar eclipses , the suns movement across the sky during different seasons , as well as space probe imagery of planets and their satellites
其他展品所介绍的，包括太阳地球和月球的运行轨道及其引起的日食和月食现象，太阳在不同季节的轨迹，以至太空船探测行星及其卫星之旅。 |
| 10. | The three main theories ( ideas ) are ( 1 ) that the moon was born from the earth , ( 2 ) that the earth and the moon were born together at the same time from the same cloud of gas and dust , and ( 3 ) that the moon was born someplace else in the solar system and then captured by the earth ' s gravity
主要存在着三个理论： （ 1 ）月球产生自地球， （ 2 ）地球和月球在同一时间从同一气云和尘埃里同时产生， （ 3 ）月球是产生在太阳系的其它某个地方，而后被地球的地心引力所捕获。 |
