boast：(of a person, place or thing) possess (a feature that is a source of pride).
boast 的意思是“有”“拥有”，但含有“自豪”的意味，可以翻译为“以...引以为豪”或“高达”。比have翻译的意思更加准确。
当boast表示“自夸”时，通常后面需要+of/about
牛津释义：
1. to have sth. that is impressive and that you can be proud of
eg. The hotel also boasts two swimming pools and a golf course.
2. (about/of sth.) to talk with too much pride about sth. that you have or can do
eg.1) She is always boasting about how wonderful her children are.
2) He openly boasted of his skill as a burglar. (burglar n.夜贼，窃贼)
3) I do not want to boast, but I can actually speak six languages.
