请问,“a boy called Tom”和“ a boy is called Tom”有什么区别? A boy called tom有两个意思?A boy called tom好像可以有两个意思1.一个名叫Tom的男孩2.一个男孩打电话给Tom they ____manatee A are called B called不是可以说a boy called Tom.但是答案却是A a boy called The boy called Tom 为什么called要加ed? He is talking with a boy ----- ___ Tom A.call B.called C.calls D.calling He is a boy called Tom.called前面应该加be吧,才有被动的意义 He is a boy called Tom.called在句子中是什么词性?在句子做什么成分?什么用法? He is a boy called tom.他是一个叫tom 的男孩为什么不是be called难道不是被动语态么? the letter is from a boy called TOM同义句the letter is from a boy （ ）（）（）（）TOM the boy is called Tom.同义句怎么改 The boy who is called Tom is my brother.句子成分 be called与called的区别This is a boy called TomThe boy is called Tom 为什么上面一句是called 而下面一句是 be called?I am talking with a girl called Alice.She is very outgoing.(同义句）The outgoing girl who I am talking with is ca 英语call的用法i piayed with the boy ( )Tom Greeni piay with the boy ( )Tom Greeni am piaying with the boy ( )Tom Green选择：A.call B.calls C.called D.calling called 和 with the name ofDo you know the boy ___ Tom?A.called B.with the name of C.calling说明原因。 Do you know the boy called Tom?为什么在这里用“called”? I know the boy -------- Tom横线上填is called 还是 called 过去分词作定语表被动关系的用法额,怎么区分它和被动语态?比如A boy called tom 为什么是called,难道不应该是is called吗?拜托讲清楚点.
