The stretch of Earth history that began about two million years ago and ended about 10,000 years ago, when great ice sheets grew and melted again and again over much of the north. People loosely call it 'the Ice Age', though actually there were several ice ages inside this one period, with warmer gaps between them.

The stretch of Earth history that began about two million years ago and ended about 10,000 years ago這是地球歷史上大約從兩百萬年前開始、到大約一萬年前結束的一段時期，when great ice sheets grew and melted again and again over much of the north那時北半球大部分地區的大冰層一次又一次地擴大又融化。People loosely call it 'the Ice Age'人們常隨口稱它為「冰河期」，though actually there were several ice ages inside this one period不過其實這一整段時期裡有好幾次冰期，with warmer gaps between them中間還夾著比較溫暖的間隔。

Modern humans appear in this time; many huge animals, such as mammoths, die out near the end of it.

Modern humans appear in this time現代人類就是在這段時期出現的；many huge animals, such as mammoths許多巨大的動物，像是長毛象，die out near the end of it在這段時期快結束時滅絕了。

You can use Pleistocene as a name (the Pleistocene) or as an adjective (Pleistocene ice, Pleistocene mammals). Geologists placed it as the 'newest' of the old -cene chapters, before the still-newer Holocene — our own recent time.

You can use Pleistocene as a name (the Pleistocene)Pleistocene 可以當名詞用（the Pleistocene），or as an adjective (Pleistocene ice, Pleistocene mammals)也可以當形容詞用（Pleistocene ice、Pleistocene mammals）。Geologists placed it as the 'newest' of the old -cene chapters地質學家把它定為那些古老「-cene」年代裡「最新」的一個階段，before the still-newer Holocene在更新的 Holocene（全新世）之前——our own recent time也就是我們現在這個近代。
