6·the rest of the water molecule becomes a pair of hydrogen atoms, which is also useful).

其余的水分子变成仍有用的一对氧原子。

7·In a semiheavy water molecule, one hydrogen atom (H) is replaced with a heftier version called deuterium (D).

在半重水的水分子中，一个氢原子（H）被一个称之为氘（D）的氢原子的同位素所取代。

8·Water is actually quite simple, but the way the water molecule is formed gives water its unique properties.

水事实上是非常简单的，但是水分子的构成赋于水独特的性质。

9·However, each time of plants take in one molecule of carbon dioxide gas, it losses hundreds of water molecules.
