rice的复数形式是rices。rice的基本意思是“稻”，也可指“稻米，大米”，还可指“米饭”。rice为不可数名词，因此说“一粒米”要用a grain of rice；“多粒米”要用grains of rice；“两碗米饭”要用two bowls of boiled rice。

例句：

They have many kinds of premium and quality rices.

他们已经开发出了若干种品质优良的大米。

Thailand exports its fine rices around the world.

泰国将精米出口到世界各地。

A total of 15 cultivated rices were evaluated for the cold tolerance at booting stage under low temperature controlled.
