问题描述：
It is much colder today that of yesterday.为什么用that of
为什么有of
答
应该是It is much colder today than yesterday.
that of 是即的意思，不应放在这儿。
答
我怎么觉得是D呢？！~~
D 连词than的前后句子结构应当相同，前面是it is，结构是it+be动词，故后面的也应该是it+be动词。由于后面的时间是昨天，所以动词时态应为过去时，所以完整的句子是It's much colder today than it was yesterday. 这里的it代指天气(the weather)
答
是It is much colder today than that of yesterday吧? that 指代天气 不是跟昨天比 而是跟昨天的天气比 所以要用that of yesterday 表示昨天的天气
答
that特指昨天的天气
