as effect such as temperature therefore

as effect such as temperature therefore
In the natural world, climate change has had a bad (1)
effect
on some areas. For example, the Arctic (北极) has experienced a rapid increase in (2) temperature
, causing ice to melt. This situation affects the polar (极地) ice cap, where ice reflects (反射) sunlight back into space. (3) As
ice melts, less sunlight is reflected, causing the earth to have more heat. (4) Therefore
, the melting of ice can lead to another round of warming. Animals like polar bears, whose homes are in these icy areas, have more difficulty in finding food, leading to a drop in their populations (数量). For animals (5) such as
seals and walruses (海豹和海象), the loss of ice means they have fewer places to rest. As ice keeps melting, these animals may finally have no choice but to move to more northern places to find cooler temperatures and safer ground.答案
1. effect
2. temperature
3. As
4. Therefore
5. such as
2. temperature
3. As
4. Therefore
5. such as
