答案：4. B [解析]细节理解题。根据 Chicken 部分的“But the birds were small and their meat was not delicious. So people only kept chickens to take part in sports races.”可知，鸡的体型小且肉不好吃，所以人们养鸡只是为了让鸡参加体育比赛。故选 B。
5. D [解析]推理判断题。根据 Chocolate 下的“2,000 years ago，only people in Central America drank chocolate. In Europe，chocolate drinks started to get popular in the 1500s when sugar was put in it.”可知，2000 年前，只有中美洲的人喝巧克力，16 世纪时，当糖被加入巧克力饮料中，它开始在欧洲流行起来。由此可推断，欧洲人一开始不喜欢巧克力是因为它不甜。故选 D。
6. C [解析]推理判断题。根据 Tomatoes 下的“In the beginning，people were afraid of eating tomatoes because they thought tomatoes were poisonous plants. One day，a brave man ate the first tomato. People were surprised that he didn't die.”可知，当有人吃了西红柿后没去世，人们感到惊讶，由此推测，当时人们认为西红柿有毒而不敢吃，所以如果有人吃了它，他可能迟早会去世。故选 C。
7. D [解析]主旨大意题。通读全文可知，本文主要介绍了一些日常生活中常见食物的历史，包括鸡肉、巧克力、西红柿和冰淇淋的起源及发展历程。D 选项（今天日常食物的历史）符合文意。故选 D。
