【分析】
一、 no longer与no more的意义区别
1.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.
2.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.
二、时态区别
1.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.
2.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.
三、位置区别
当修饰动词时,no longer通常置于be或行为动词前；no more一般置于行为动词后.not...any longer与not...any more常置于句末.如：
She could no longer find a way to get into the valley.她再也找不到进山谷的路了.
Time or opportunity lost will return no more.机不可失,时不再来.
四、修饰动词区别
1.no longer / not...any longer 习惯用来修饰表示状态的持续动词(如wait,live,work等).如：
Don't wait any longer.别再等了.
She could not keep up with him any longer.她不能再赶上他了.
2.no more / not...any more通常用来修饰表示具体动作的瞬间动词(如go,stand,visit等).如：
We couldn't stand it any more.我们不能再忍受了.
五、作用区别
两者都可用来修饰动词,在句中作状语.当no more作“不再(有、存在)”解时,还可作定语和宾语.如：
Later when they are far away from the earth and there is no more gravity,they find they are unable to stay in one place.过后,当他们远离地球,到了不再有地球引力的地方时,他们发现自己不可能停留在一个地方不动.(作定语)
I have no more to say.我没有什么要说的了.(作宾语)
综上所述,考例1应选D不选B.考例2应选D.A项中的not...any more位置不对,B项中的not...any longer位置也不对.且A和C项中的not...any more通常不修饰谓语动词work.
