问题 According to Pro. Salt, plants that take up large amounts of metal in their tissues can be used to ______.
Mr. Salt wants to create anti-cancer foods by ______.

选项 A、copying tissues from wild plants that take up selenium naturally into crop plants
B、copying genes that causes the plants to take up selenium from the soil
C、moving selenium from the tissues of wild plants into crop plants
D、moving genes from wild plants that take up selenium naturally into crop plants

答案D

解析 见文章的第六段。“Mr.Salt says foods to fight cancer might be created if genes from these plants could be moved into crop plants”,意为“Salt先生说如果能通过将这些植物的基因移进作物类植物中去,也许就能创造出抗癌食品。”A、B、C皆为表述接近的迷惑性选项,解题时要小心。
