全文聽(tīng)寫，童鞋們注意數(shù)字聽(tīng)寫規(guī)則哦~~

50 years ago, most people lived in rural areas. But the world has changed. By some point next year, more than half of all people will live in cities, for the first time in history. So says the most recent estimate from the United Nations. City life is not always a bad thing, but many experts worry about this process of urbanization. A new report says it is having a huge effect on human health and the quality of the environment. Of the 3 billion people who live in cities now, the report says, about 1 billion live in unplanned settlements.
50年前，大部分人都生活在農(nóng)村。但是世界已經(jīng)發(fā)生了變化。到明年的某些時(shí)候，超過(guò)一大半的人都會(huì)居住在城市中，這將是歷史上的第一次。這是美國(guó)最近的一項(xiàng)評(píng)估結(jié)果。城市生活不一定總是不好，但是很多專家這樣的城市化進(jìn)程表示了擔(dān)憂。一項(xiàng)新的報(bào)告顯示城市化已經(jīng)對(duì)人類的健康和環(huán)境質(zhì)量產(chǎn)生了巨大的影響。這份報(bào)告顯示：在所有居住在城市里的30億人來(lái)說(shuō)，大約有10億是處于居無(wú)定所的情況。 ——譯文來(lái)自: 悠悠和嘟嘟
