1．(2020·新高考山东卷)Often，only a small part of a museum's collection 41.________ (be)on display.Most of it is stored away or used for research.
解析： 考查一般现在时和主谓一致。根据时间状语Often可知该句应用一般现在时，设空处为谓语动词，主语为only a small part of a museum's collection是单数形式，故此处用is。
答案： is
2．(2019·天津卷)Amy，as well as her brothers，________(give)a warm welcome when returning to the village last week.
解析： 考查动词的时态、语态和主谓一致。句意：埃米和她的兄弟们上周回到村里时受到了热烈的欢迎。A as well as B作主语时，谓语动词的单复数由A，也就是本题中的Amy决定；由last week可知give表示的动作发生在过去，且Amy与give之间是被动关系，故填was given。
答案： was given
