答案：He has repaired his bicycle.
同义句：The bicycle
has been repaired by
him.
解析：根据“已经”我们知道这个句子应该使用现在完成时。
现在完成时含义：是过去的动作或状态持续到现在，或对现在造成的影响，可能持续发生下去。
它的构成是：主语+助动词(have/has) +动词的过去分词。（done）
主语是 he 所以助动词选择has，
所以答案是
He has repaired his bicycle.
同义句：可以改为被动句。
The bicycle has been
repaired by him.
(自行车被他修好了。）
