关于dress u厚理江事如极花复考积p这个用法
问题补充说明：例1.Last Christmas, the circus owner, Jimmy Gates, decided to take some presents to a children's hospital. Dressed up as Father Christmas and accompanied by a 'guard of honour' of six pretty girls, he set off down the main street of the city riding a baby elephant called Jumbo.2.She was dressed up in her Sunday best.3.After having decided to take some presents to a children's hospital,the circus owner,Jimmy Gates dressed up as Father Christmas and set off down the main street of the city riding an elephant called Jumbo.4.He was going to lend me a policeman's uniform so that I could dress up for the party.我想问的是dress up不是应该要用被动语态的吗?为什么例3,4直接用主动语态的呢?为什么例1,2就用被动?请问例34有错吗?例134都是出自于新概念英语2册第65课，两种用法都对吗?请讲解一下个中原因，谢谢。
