Can we thrive on other planets in the universe?
On another planet 在另一個世界
Earth is part of the solar system. Our sun's core provides the power. It is surrounded by eight planets: Mercury, Venus, Earth, Mars, Jupiter, Neptune, Uranus and Saturn. Pluto lost its planet status in 2006 and is now considered to be a dwarf planet.
地球是太陽系的一部分。太陽的核心是整個太陽系動力的源泉。八大行星圍繞著太陽，分別是：水星，金星，地球，火星，木星，海王星，天王星和土星。在2006年冥王星失去了行星的地位，現在被認為是矮行星。
如果形容一個人是在另一個世界，那就表示這個人對眼前的事情心不在焉，漠不關心。
例句
Jane's on another planet – she went to buy some apples and bought lemons instead!
John really doesn't listen in class; he seems to be on another planet.
請注意
如果說一個人 living on another planet 那么意思就是說這個人一點都不現實。
例句
He thinks we'll be able to drive to Paris by tonight – he's really on another planet!
If she thinks we can afford a two-week holiday in Spain she's living on another planet!
