【正确答案】 A few years ago, migrant workers in Beijing often complained that they could not afford a house. But now, they unexpectedly find that renting house has also become very difficult. According to the latest data released by the department concerned, in this September, housing rents rose by 4.5% year on year, which have been increasing for 55 consecutive months. Due to the soaring rents, more and more young people have to give up the opportunity to work in Beijing and choose to go back to their hometowns. It is no doubt a loss for the long-term development of a city.

【答案解析】1．第1句中的“抱怨买不起房子”是汉语中的连动句，翻译时，需把“买不起房子”处理成“抱怨”的内容，用that引导的宾语从句来表达，译作complained that they could not afford a house。
2．第3句中的“相关部门发布的”较长，故将其处理成后置定语，用表被动的过去分词短语来表达，译作released by the department concerned。
3．第3句中的“上涨4．5％”应译为rise by 4．5％。翻译时需弄清楚rise by和rise to。两者区别在于：rise by表示“上涨了多少”：rise to则表示“上涨到多少”。
4．第3句中的“已经连续55个月上涨”中，“已经连续”表示某事已经发生且现在还在持续进行，宜用现在完成进行时，译为have been increasing for 55 consecutive months。
