2018年托�？谡Z場景例句：人類活動對動物進(jìn)化的影響

　　新托�？谡Z題目回憶版本一：

　　考題回憶：人類活動對動物進(jìn)化(evolvement)的影響：

　　一是動物身體變小，因為人類偏向捕獵大體積動物作為食物。比如魚，當(dāng)人們把大魚撈走，小魚能夠留下來并且pass their genes to the next generation;

　　二是大腦變大，因為動物要適應(yīng)changeable environment，聰明的會活下來。比如老鼠，學(xué)會了在城市里生活和尋找食物，腦子聰明的會活下來并把基因傳給下一代。

　　新托�？谡Z題目回憶版本二：

　　聽力：lecture;動物的 evolution 與人類活動有關(guān)。第一，動物體格越變越小。比如魚，人們會把大魚捕走，只有小魚能存活下來，所以魚就 pass their genes to the next generation，魚就變小了。第二，動物大腦越變變大。比如 mice，mice 學(xué)會了在城市里生活和尋找食物，腦子聰明的會活下來，所以就 pass their genes to the next generation。

　　托�？谡Z范文一：

　　The professor talks about two ways how human activities affect animal evolution.

　　Firstly, it causes animals to grow smaller. This is because human tend to hunt those animals bigger in size as food source. Take fish as an example, when people caught huge number of big fish, smaller fish sustain and they are able to pass their genes to the next generation;

　　Secondly, animals began to have larger brain, since they have to adapt to changeable environment and survive. The professor then gives an example of mice, in order to survive in the city and search for food, mice evolve to be smarter, and only the smarter ones will survive and pass their gene to the next generation.
