水是一种神奇的物质,它覆盖了地球70%的表面。它之所以如此特殊,完全是由它的分子所导致的。每个水分子由两个小的氢原子和一个氧原子相结合。这使得它们一端呈正电,另一端呈负电。因此它们砰然结合,并且像磁铁一样粘住彼此。
Water is a magical substance that covers 70% of the Earth’s surface. It is so special, completely caused by its molecules. Each water molecule consists of two small hydrogen atoms and one oxygen atom. This makes them positive at one end and negatively charged at the other. So they snap together and stick to each other like a magnet.
