问题 Ellen was pleased to hear people praise her great tan skin. [br] If you stay in the sun overtime, the cells called melanocytes will produce extra melanin, the brown pigment, which makes your skin look "tan".
选项 A、Y
B、N
C、NG
答案 A
解析 第四段第五句话指出"So when you decide to have a marathon roasting session in the sun，cells in your skin called melanocytes go to work overtime．They produce an extra supply of melanin，the brown/black pigment that gives your skin its color．That extra melanin makes your skin darker，and that’s why you ’tan’"皮肤内的黑色素细胞工作时间过长会产生多余的黑色素，这些色素会改变你皮肤的颜色，使你变“黑”，所以那就是你为什么变得“黝黑”的原因，而题干表达的意思与原文正好相符，因此答案正确。
