Tackling it seems madness for a bat weighing just half an ounce. 捕捉毒蝎对于仅有十四克重的蝙蝠来说近乎疯狂
and, with it, half the indri families that once lived there. 而那里曾栖息着半数的大狐猴家族
but it's home to half of all the plants and animals on land. 却分布着世界上一半的动植物物种
but, for one and a half million penguins, 但是对于一百五十万只企鹅来说
and hold his breath for half an hour. 屏住呼吸长达半小时
One and a half miles down, at a site known as Nine North 距海面一英里半,一个叫北九地区的地方
It covers more than half the surface of our planet 地球表面多半被海洋覆盖着
not for one month as it does in the Taiga but for half the year. 不是北极的一个月,而是半年
and they can grow by half a meter a day. 它们每天还能长半米
They can be three meters long and weigh half a ton 可以长到3米长,半吨重
