1. When the south pole is towards the sun, the southern half of the world (or the Southern Hemisphere) is warmer, and it has its summer (December, January and February).
    当南极斜向太阳时，地球的南半部（南半球）就比较温暖，处于夏季（十二、一、二月）。

2. This country is on the Easten Hemisphere.
    这个国家在东半球。

3. So when the north pole tips towards the sun, the northern half of the world (or the Northern Hemisphere) is warmer and has its summer (June, July and August).
    所以，当北极斜向太阳时，地球的北半部（北半球）就比较温暖，是夏季（六、七、八月）。
