上午,妈妈买回了一袋活蹦乱跳、身披铠甲的小虾子,个个青得发绿。中午吃饭时,妈妈端上的虾子却变成了美丽的桔红色。我联想到,过去煮螃蟹也是生的青、熟的红,而且死的螃蟹也微泛红哩!于是我问妈妈:“为什么生虾青,熟虾红呢?”“因为有色素呀!”妈妈只回答了个大概。我并不满足,就去请教爸爸。 In the morning, my mother bought back a bag of small shrimps that were scampering and wearing armor. All of them were green and green. At noon, the shrimp on her mother’s side turned beautiful orange. I think that in the past, boiled crabs were also green and ripe red, and the dead crabs were also slightly reddish! So I asked my mother, “Why do you have raw shrimp and cooked red shrimp?” “Because of pigments!” Mom only answered one. If I am not satisfied, I will consult my father.
