四級聽力原文

I bet our ancestors returned home from hunting wild animals and gathering nut ,and complained about how little time they had to paint battle scenes on their cave walls.

我打賭我們的祖先涉獵和采集堅果回到家後，也會抱怨他們沒有時間把戰爭場景畫在他們洞穴的墻上。

i bet 我確信，我打賭。後面是賓語從句，returned, and complained 是並列關系，都是祖先ancestors以前發生的動作。

The difference is that the boss of the animal hunting and the head of nut gathering probably told them to "Shut up" or"No survival for you!"

不同的是，打獵動物的老板和采集堅果的主管會讓他們閉嘴或者開除他們。
