这里的 foods 是可以用的
fodd 在一般情形下是不可数的.
但是在句子里提到food表示食物“种类”(着重指‘不同种类的食物’)的时候,是可数的.
例如:我喜欢不同的食物和水果.I like different kinds of foods and fruits.
平时提到食物,这里是不可数.
例如:
我买了些食物 I bought some food.
我们店卖外卖.We sell take-away food.

第二句 加 in,像2楼所说的,我错了
live 是不及物动词,后无宾语就用live
live+in 相当于及物动词,后需接宾语
副词前的介词常省略掉.
如:
Where are you living?
Which ciy are you living in?
I want to find a place to live in.
I don't know where to live.
I don't know which room to live in.
He has lived here/there for a long time.
