In some places leaves will fall off the trees before they change colors in the autumn.
Leaves show different colors other than green in the fall because the carotenoids and anthocyanins are then______.
选项
答案
unmasked
解析
根据题意和题干中的carotenoids and anthocyanins定位到第二个小标题下第2段的末句The carotenoids and anthocyanins that are present in the leaf are then unmasked and show their colors.此处需填入表语成分。题目中的Leaves show different colors other than green“叶子显现出除绿色外的其他颜色”和原文中的show their colors“(类胡萝卜素和花青素)显现出自身的颜色来”表达的实际是同一概念,故答案就是unmasked。
