英语翻译：我们以米饭为主食 We_________________.

应该是 We have rice as a staple food.
或者是 Rice is our staple food.---米饭是我们的主食。这用在口语会比较口语化吧，就是可以一下子听懂的， 上一句比较绅士的说法吧 呵呵！！！

以米饭为主食 : live on rice
例句：
以米饭为主食是大多数亚洲人的习惯。
Live on rice is most of the Asians' manners.

所以，我们以米饭为主食：we live on rice.

We have rice as a staple food.

We have rice as a staple food.

We mainly feed on rice.
应该是这样了
