心身疾病具有下述特点叙述错误的是（） A.发病前存在明显的心理社会因素应激因素 B.

A long time ago, in 1893, in the United States, some people were talking about fruits and vegetables. They asked, “What are fruits and what are vegetables? How are fruits different from vegetables and vegetables different from fruits?” They talked for a long time and then they decided, “We eat vegetables as part of a meal, but we eat fruits before or after a meal.”

In real life, people do not think the dictionaries give the right meaning of a word. For example, the dictionaries say that tomatoes are fruits. But few people know that. Most people think they are vegetables. They call them vegetables and eat them as vegetables. To most people, fruits mean sweet things like apples, pears, oranges and watermelons.

What are vegetables then? We call many plants and grasses vegetables. Some people think some fruits are vegetables, such as apples, pears and bananas. But to most people, vegetables mean things like potatoes, onions and carrots.
