n.河馬（hippopotamus的復(fù)數(shù)形式）

An order of hooved mammals of the subclass Eutheria (including pigs and peccaries and hippopotami and members of the suborder Ruminantia) having an even number of functional toes. 有蹄哺乳動(dòng)物的一目，屬于真獸亞綱（包含豬、野豬、河馬和反芻亞目的成員），功能腳趾為偶數(shù)。

Once we came across a school of hippopotami, which rose, and bellowed dreadfully at us within ten or a dozen fathoms of the boat. 有一次我們遇到一群河馬，離我們的船有十至十二碼的樣子，正一沉一浮地怪叫著朝我們游來(lái)，樣子十分可怕。

Visitors may have the opportunity to enjoy seeing with their own eyes giant animals such as Elephants and Hippopotami devour their food ravenously. 最近隆重推出"動(dòng)物進(jìn)食大觀"和"猴山新貌"等項(xiàng)目，游客們可親眼目睹河馬狂張大口、大象巧用長(zhǎng)鼻和狼吞虎咽的情景。

And wallowing in the water holes and dams, you'll spot the ears and eyes of hippopotami which weigh between 200 and 300kg (441 and 661lbs). 你還會(huì)看到在池塘和水庫(kù)中打滾的河馬露出的耳朵和眼睛，它們重200到300公斤（441到661磅）。

some hippopotami. 好幾頭河馬。
