为什么火烈鸟是粉红色的?
Flamingos are not born(天生的) pink. Baby flamingos are gray and white. They eat shrimps(虾) and algae(水藻). The foods turn their feathers(羽毛) pink over time(隨着时间的推移).
为什么蔬菜要放在冰箱里保存?
Vegetables keep on(继续) ripening(成熟) even(即使) after we pick them. The cold air in a fridge slows down(使慢下来) the ripening. If you dont keep vegetables cold,they will go bad faster.
