这几个词 要弄清楚 还是比较难得.
首先 no more= not any more
no longer = not any longer
比如：He can eat no more.= He can't eat any more.
He no longer lives here.= He doesn't live here any longer.
难点在于 more,longer 的选择.
more 着重,多少（比如,次数,能吃多少东西等）
longer 着重 ,时间
比如：他不再去那里了.这里着重的是次数.所以我们说 He goes there no more.或者
He doesn't goes ther any more.
他已经不住在这里了.这里着重的是 时间
所以说：He no longer lives here.或He doesn't live here any longer.
比较一下 He doesn't come here any more.
