You might find I can be of more assistance than you think
谁能给我分析一下这个句子的语法.
宾语从句:
主句:You might find
后面是从句: I can be of more assistance
再后面 than you think 是 than引导的定语从句
than在这里用作关系代词,引导定语从句,但要注意主句中必须有比较级字样和than前后呼应.例如:
He smoked more (fewer) cigarettes than he bought.
他吸的香烟比他买的(弄到的)要多(少).
这里than在语法功能上相当于that/which的功能,但是这里不能改成后者,因为主句中有比较级more.
than作关系代词时,一般用在形式为比较级的复合句中,其结构为形容词比较级(more)...than+从句,than在从句中作主语,相当于that,代表它前面的先行词.(这时,它兼有连词和代词的性质,也有学者认为这种用法的than是连词,后面省略了主语what.)
如:①The indoor swimming pool seems to be a great deal more luxious than is necessary.室内游泳池过于豪华. ?
②He got more money than was wanted.他得到了更多的钱.
