下面这句话有没有语病,急.
××× is undoubtedly a good mother,someone she can look up to and set an example for her.
想表达的是“某某毫无疑问是个好母亲,是她所能敬仰的人,是为她树立了榜样的人.”
如果错了的话帮忙修改.希望不要变动大体框架,也即排比.
=打漏了，本来打算打的是
××× is undoubtedly a good mother,someone she can look up to and someone who has set an example for her.
哪个对还是两个都可以还是都错了？
