比较级than的用法

    用于对两者进行比较。在than后面的比较状语从句内，与主句相同部分可省略，而不同部分须写出。有时 than后的从句有主语、谓语颠倒现象。由于than既可用作连词也可用作介词,所以当后接人称代词时,可用主格也可用宾格。通常认为在正式文体中多用主格,在口语或非正式文体中多用宾语。
    
    比较级than的用法
    比较对象在范围上不能包括主语本身在内。
    1.He is taller than any other student in his class.
    或把any other student 改为the other students 或改为the others或改为anybody else，但不能把other去掉，说成He is taller than any student in his class. 因为他班里的任何学生就包括他本身在内。
    2. Shanghai is larger than any city in China 就不对，但Shanghai is larger than any city in Japan 就对。
    比较级前面可加much/far/a lot/a little/a bit/even/still以及名词短语修饰，叫程度状语。
    Watching game shows is far more enjoyable than watching sports news.
    这种比较结构可用于两个主语、两个宾语、两个状语之比。
    than是比较的意思,不能用from(从)代替
    一、rather than用作连词，连接两个平行结构。既可以表示主观愿望上的决择，“与其…宁可…”，也可以表示客观程度上的差异，“与其说是…不如说是…”。例如：
