1.Dr. Chan says the WHO is no longer operating "at the level of top performance that is increasingly needed, and expected."

no longer与no more的意义区别

   no longer中的longer是副词long的比较级,long有after a certain point of time(在某一时刻以后)之意,着重表示时间的不再延续,意为“如今不再”。no longer等于not... any longer。

  no more中的more是many / much的比较级,more有again之意,着重表示数量或程度的减少,意为“再也没有更多(大)的数量(程度)”。no more等于not... any more。

时态区别

   no longer / not... any longer表示不再继续或再现过去某一时刻发生或存在而一直延续的动作 / 状态时,常用于过去时、现在时或将来时的句子中。如:

  He was no longer a thief. 他不再是小偷了。

  When there is no gravity, our feet no longer stay on the ground. 如果没有重力,我们的脚就不能再站稳在地面上。

  no more / not... any more表示再也不重复过去反复发生的动作时,常用于过去时或将来时的句子中。如:

  Now she wasn't afraid any more. 现在她再也不害怕了。
