听力材料：

1： Vikings relied on fish for food and climate change didn’t change the ocean and the fish.（维京人以鱼类为主食，并没有面临饥荒）

2： When the Vikings left, they took away all their valuables and tidied up, if they were driven out they would have been in a rush.（维京人离开时整齐有序，并没有落荒而逃的迹象）

3： The formal trade was cut off but the illegal and unofficial trade was still on-going. Even the Norwegian King complained about the illegal trade was hard to control. （虽然正式的贸易被禁止了，但是非法的和私下的通商依旧繁荣）

阅读材料：
