請將下面這段話翻譯成英文：
上海正在轉(zhuǎn)型成為一個世界級的城市,這也推高了上海的生活成本。農(nóng)民工來到城市工作，是因為他們賺得比在鄉(xiāng)下多。但是由于沒有當?shù)貞艨冢╨ocal registration),他們無法享受很多服務.上海大學近期的一項研究發(fā)現(xiàn)，49%的受訪者月收入低于3000元，大約合15美金一天。在中國部分農(nóng)村地區(qū)，這是一個小康(well-off life)水平的工資，但在像上海這樣的高消費城市，這些錢并不能維持多久。
參考翻譯
Shanghai is transforming into a world metropolis,which pushes up the cost of living there. Migrant workers come to the city because they can earn more than they would in the countryside. But without a local registration,their access to many services is limited. A recent study by Shanghai University found that 49% of those interviewed earned less than 3,000 yuan a month,about $15 a day in equivalent. That is the wage for well-off life in some rural areas of China，but in an expensive city like Shanghai this amount of money cannot go far.
