两姐妹用八年的时间打破了一项世界纪录，她们认为这一切都要归功于她们父亲的建议。

Two Brisbane sisters have worked for eight long years to finally break a world record, thanks to the advice from their dad. Teresa, 21, and Augnes Joy, 18, have studied 100 languages over eight years in order to learn by heart the national anthems （国歌） of the 193 countries of the United Nations (UN).

The girls achieved their goal at St John's Cathedral in Brisbane's CBD, where they sang for six hours straight,only allowing for a 10 minute break after every two hours.And while their efforts to reach their goal are admirable,the girls put it all down to the guidance of their father.“Our dad always wanted us to do something different for the world and understand the seriousness of the national anthems. He has always told us that everyone is one, and all other countries are one,” Teresa said.

The girls spent their youth researching each national anthem before learning them by heart.“Through this, we became so much more interested in learning more languages. If people want to do it, they just have to keep going, and don't give up it,” Teresa said.

After a long day of singing, the sisters were presented with certificates from three world record companies to confirm their achievement.

And with one achievement safely under the belt, the girls now hope to continue their performances internationally as soon as travel restrictions allow. They're also in the process of writing a book that will detail what it took to finally break the world record.
