What is special about carrots? A clue to what makes a carrot special is its color．Carrots are orange because they store beta-carotene(胡蘿卜素)．Beta-carotene is a way to talk about Vitamin A(維生素A)．Your eyes need Vitamin A．It helps them work． 　　When light hits your eye, very small parts inside turn the light into messages．The messages go to your brain(腦),and then you know what you're looking at．Your eye can only turn light into messages when it has a special chemical(化學(xué)物質(zhì))．That's where Vitamin A comes in．Your eyes use Vitamin A to make the special chemical．Every time your eye changes light to messages, a little bit of the chemical is used up．By the end of the day, you've looked at hundreds of things．That uses up a lot of the chemical．Your eyes need to make more． 　　What should you eat if you don't like carrots? Don't worry．Other fruits and vegetables have Vitamin A too．The secret is in their color．Most orange or red fruits store some beta-carotene, or Vitamin A．Sweet potatoes, red peppers, mangoes(芒果)are a few that have the same orange secret．Can you think of any more?
