He used to ______ on the school football team.A.was B.take C.join D.be
He used to ______ on the school football team.A.was B.take C.join D.be

He used to ______ on the school football team.A.was B.take C.join D.be
选择 D.be
知识点：used to do sth 过去常常做某事
A.was 过去式,不对的
B.take 词组：take part in 参加
C.join 词组：join in 参加
但是句子有on,没有in,因此BC直接排除了.be on 也是参加的意思.
翻译：他过去常常参加学校的足球队
