例如it is a custom in China to have some tea or other drinks before the meal------,答案是is served,为什么不能用非谓语动词served,不也是被端上吗?
追答这是省略语,你必须补全
问句:在中国,主食之前喝茶或者饮料是风俗习惯
答语:yes,it is the tea that is served before the meal-
it is that 的强调句,就是the tea is served before the meal-
你如果要用过去分词,这么用:
i am dringking the tea served
这个served 是过去分词,定语后置,修饰tea

追答这个句子的意思是:在中国吃饭之前喝一些茶或其他饮品是一个风俗。meal是被提供的,所以必须用is served。
