前句是错误的.没有这种表达.
be/ become interested in.=show/ have interest in.对...感兴趣错了 应该是I have always been interested in food
和I am always interested in food (应该是be always还是 always be 为啥)be always
be+both/all/always...
both/all/always+动作动词I have always been interested in food
和I am always interested in food这俩区别呢前者强调【到目前为止】，有可能会延续。后者表示【自始自终】，肯定延续。
