你可以用英文表达为 "An elephant is heavier than a rabbit."
这句话的来源可能是来自于人们对动物体重的比较，大象显然比兔子重得多。
下面是一些英文例句及其中文翻译：
"The elephant weighs several tons, while the rabbit weighs just a few pounds."（大象重几吨，而兔子只有几磅重。）
"Even a baby elephant is much heavier than a full-grown rabbit."（即使是一只幼儿大象，也比一只成年兔子重得多。）
"It's no surprise that an elephant can carry more weight than a rabbit – they're just built differently."（难怪大象能够承受比兔子更多的重量——它们的体型本来就不同。）
