go本来是“去”的意思,“我们一般不吃饭就去”,但一般有上下文,可以结合上下文来解释.比如：
We often go fishing on weekends,we often go without food.
我们周末经常去钓鱼,我们经常不带食物去（钓鱼）.'Have you parents ' asked the prince ,'Yes sir ,I have parents and two sister ,we are a large family ,we have no money ,we often go without food .后面没有下文，句子中的　go　是印错了还是有其他解释，如果不是表示“去”的意思，那就是引申意义“进行，生活”等，比如：How are things going?事情进行的怎么样？（“你最近如何，你近来还好吗”）你的例子go用的没错，翻译为：我们没钱，我们经常揭不开锅。直接翻译：我们没钱，我们经常生活着/过日子/(go)而没有食物句子　we often go without food　中如果没有　go　是否也能说的通，We often without food. 不行只能说We are often without food.因为有了系动词are, 这才是“主系表”，句子结构才完整。就像你不能说We Beijing.只能说We are in Beijing. 但即使这样，我觉得We are often without food.听起来也有点怪，基本没听说过，虽然语法上正确的。还是We often go without food.更地道。
