副词可以同时做表语和状语吗

The visitors are warmly welcomed by the local people. Warmly 算什么成分

同一个副词不能同时作表语和状语，
但副词可作表语,也可作状语。
如
1. Everyone is here . （ 副词here 作表语）
2. The children are playing happily . ( 副词happily 作状语）
3. His book is there . (副词 there 表语）
4. The visitors are warmly welcomed by the local people. (Warmly 作状语）

1 .副词可以做表语，主要指主语的方位，方向，动作情况。 when the meeting is over,give me a phone call.会议结束时，给我来个电话。 sorry ,i have to be off right now.对不起，我得马上走。 is anybody in ? 里边有人吗？ 2 .短语在句子中是系表结构。be 是系动词。
