PLANET EARTH From Pole to Pole
As we travel south so the sun's influence grows stronger and at 50 degrees of latitude a radical transformation begins. Summers here are long enough for broadleaf trees（阔叶树） to replace conifers. Broadleaves are much easier to eat and digest so now animals can collect their share（这里表示份，一份，份额，例如股票里面一股就是oneshare） of the energy that has come from the sun. It's summer and these forests are bustling with life.
influence单独拿出来说：
常见发音错误❌
做名词时（例句在01:00的位置）
正确发音为'influəns✔，重音在最前面，而不在f上。
在做动词时（例句在03:36位置）
可以发成in'fluəns，也有发成'influəns的，以美音多见，两种都可以。
我个人偏好in'fluəns，比较符合发音规则。
同理，increase做名词则为'increase，做动词则为in'crease。
But the good times will not last. Broad leaves must be shed in winter for their damage by frost. As they disappear, so the land becomes barren with little for animals to eat. The inhabitants must migrate, hibernate, or face months of near starvation. The Amur leopard（Amur地名，指阿穆尔，我国黑龙江，这里指远东豹，又名阿穆尔豹，东北豹） - the rarest cat in the world. Here, in the deciduous forests of eastern Russia the winter makes hunting very difficult. Pray animals are scarce, and there's no concealing vegetation.
