such as 的用法

题目

such as 的用法
Many traditional vegetarian diets,such as are common in parts of India,are made up of peas or beans and yogurt 这个句子中,such as 后面怎么直接接的是are

答案

这里such as后面省略了代词those,指代“（印度的）素食菜单”.也就是说完整的说是这样——
Many traditional vegetarian diets,such as traditional vegetarian diets common in parts of India,are made up of peas or beans and yogurt.
很多传统素食菜单,比如说印度一些地区常见的菜单一样,是由豆子或豌豆拌酸乳组成的.
