flat and apartment

When I moved into my first apartment in college, I remember telling my flat-mate Tanya I am the luckiest person in the world and she looked at me like I was a weirdo.

记得刚搬进大学公寓的时候，我就对我对床的塔尼亚说，我是世界上最幸运的人，当时她看我的眼神就好像在看一个怪人。

"I was preparing rice and beans for dinner when the whole six-story [apartment building] fell flat in seconds," she told the Sun.

“当整个六层(住宅楼)顷刻倒塌的时候，我正在为晚餐准备米饭和豆角”，她告诉《太阳报》。

And financially, she benefits from living on a train: The flat-rate ticket costs her about $380, whereas she had to pay about $450 for her previous apartment.

而且从经济角度看，在火车上居住还是比较划算的：一张通票的价格是380美元，而她之前的公寓需要450美元。
