1 可以。例句如下：

"What was she wearing?" "I think she had on a dark suit."

2 far more than that 可以用 much more than that.

请教两个问题：

1. have on 穿着...， "on" 是副词，那么，have a red coat on 可以等于have on a red coat吗？

2. far more than that 可以用 much more than that替换吗？

第1个问题解答如下

动词+副词构成短语从句，如果宾语为名词，名词可以放在中间，也可以放在后面，如果宾语为代词，只能放在中间。

(1)have on +名词=have +名词 +on穿着/ 戴着某事

She had on a red coat today

=She had a red coat on today

她今天穿了一件红色外套。

(2)have +宾格代词+on

Mary bought a pair of shoes,but she didn't have them on.

玛丽买了一双鞋子，但是她没有把它们穿上。

第2个问题解答如下

far，much都可以用来修饰比较级，因此完全替换。

far more than that 完全可以用 much more than that替换
