to ask for
牛津第四版对other than的解释如下：
other than：prep (esp after a negative 尤用於否定词之後)
1 except 除了（表示所说的不包括在内）:He never speaks to me other than to ask for something.他除了向我要东西,从不跟我说话.* She has no close friends other than him.她除了他以外没有好朋友.
2 different(ly) from; not 不同於; 而不:I have never known him behave other than selfishly.我只知道他一向自私自利.* She seldom appears other than happy.她很少有不高兴的时候.
