这句英文语法有错误吗？

Question

Futhermore, the South Korea which is closest country from Japan has became a suffer of the Japanese tsunami too. （这样符合西方人的语言习惯吗？）
（原句：离日本最近的韩国也成了日本海啸的受害者之一）

Answer 1

这句话是有语法错误的。became是过去式，而不是过去分词。应该将其改为BECOME才符合现在完成时的语法要求。

Answer 2

Futhermore, South Korea ，which is the closest country to Japan has become one of the victims of the Japanese tsunami, too.

Answer 3

Furthermore, South Korea, which is the closest country from Japan has became a sufferer of the Japan tsunami too. 稍微做了整改，请笑纳~
