问题描述：
1.they will fly to Washington(where) they plan to stay for 2 or three days.括号里用where（关系副词）,而不是which等关系代词.是因为主语、宾语都不缺.在本句里,washington是主语?to stay for 2 or3years
2.he never watches him in thestreet.不是说never（否定词）后面跟原形吗?怎么watch还加es,比如：he dosen't play football
答
1、在从句中,they是主语,stay是谓语,由于是不及物动词,不需要宾语,where（相当于in which,即in washington)做地点状语
2、never只是个程度副词,谓语动词的时态和语态和它没有关系,语态由主语单复数决定
