这个英语句子不会,He also put up some signs ...问题补充有, He also put up some signs asking for old bikes and called up his friends and told them about the problem. 这个句子翻译倒是行,但是顺序很乱求指点
他也经常张贴一些寻找旧单车的广告,而且打电话给他的朋友们告诉他们这个问题.asking for old bikes为非谓语动词短语修饰signs.called up his friends 与put up some signs .同级and told them about the problem.我认为这句可以看作补充说明,就像古文中“而”的作用.
He also put up some signs asking for old bikes (这个asking……bikes修饰signs)and(he) called up his friends (他打电话给朋友们)and(then he) told them about the problem.(然后她告诉了他们这个消息)
