Of course, we know it is not a star at all but the second planet from the Sun and the sixth largest.
当然，我们都知道金星其实不是恒星，而是距太阳距离第二，体积第六大的行星。
注：
1，second planet from the Sun（距太阳距离第二的行星）≈离太阳第二远的行星≈从太阳数过来的第二颗行星≠太阳的第二大行星

Venus is usually visible with the unaided eye. Sometimes referred to as the "morning star" or the "evening star", it is the brightest star in the sky.
通常情况下，我们用肉眼就可以看到金星。有时金星被称为“启明星”或“长庚星”，它是天空中最亮的星。
注：
1，unaided eye（肉眼）≈naked eye≠没有辅助的眼睛
2，referred to（被称为）≠被提到
3，morning star（启明星）≈晨星
4，evening star（长庚星）≈晚星

It is the brightest object in the sky except for the Sun and the Moon.
它是天空中除太阳和月亮之外最亮的天体。
注：
1，object（天体）≠物体

Venus probably once had large amounts of water like Earth, but it all boiled away so now it's quite dry.
金星上曾经像地球一样，存在大量的水，但是这些水分全部汽化了，所以如今的金星基本没有水分。注：
Boil away（汽化）≈蒸发≠被煮干
