beside(s)
1.在现代英语里，beside只用作介词，作“在…的旁边”或“跟…没有关系”解。例如：The pioneer is sitting beside the mayor和That is beside the question。besides可以用作介词，作“加在…以上”解，也用作副词，作“而且”解，如There are five members besides Mr and Mrs Winston和I am very tired, besides, I have a cold。把beside和besides混用，不好算错误，但总是不好。
2.besides后面偶尔接没有to的不定式。例如：That afternoon I had nothing to do besides answer letters.
3.besides后面偶尔接以that引导的从句。例如：Besides that he explained the theory, he gave us several examples.（他不但解释那理论，而且给了我们好几个例子。）
