we don't allow ()in the classroom为什么括号里填eating呢?
they would not allow him()across the enemy line为什么这里又填to risk going呢?求讲解,

allow 后直接接动词,则要转换成动名词形式；
而第二个句子不是直接接的动词,它中间有宾语,于是就变成allow sb.to do sth.
意思是：他们不予许他冒险穿过安全线.
再问：中间为什么有宾语就要用to do的形式呢？i'm sorry()so long,i forgot to tell you in advance where i had put my key. 这里有明显的现后关系吗？只因为forgot是用的过去式，所以要用完成时态吗？完成时态只能在谓语动作之前的动作才能用吗？难道就没有别的用法了吗？求详细讲解
再答：有些是固定搭配。它就必须那么用。你可以查一下牛津高阶字典对ALLOW用法的解释。因为语言是约定俗成的，它用了那么多年都是这样的习惯，所以编成字典，精炼成语法也只不过是对口头语言的总结。没有那么多为什么的……真的~
再问： i'm sorry()so long,i forgot to tell you in advance where i had put my key. 这里有明显的现后关系吗？
再答：括号里是什么词？有先后关系啊。我是先把钥匙放在某个地方，然后才忘了告诉你的啊~
再问：括号里是to keep you waiting,find后面通常接什么，他的宾语补足语呢？比如find sb然后接什么，find sth 后面接什么的，find有可以直接接什么呢？
再答： find sth. 找到什么，发现什么 find sb. sth.为某人找某样东西 find that……接宾语从句要不咱私聊吧……唉~
