问题描述：
解释解答英语专八人文语言语义学（semantics）题目,搞晕了,懂得来~
When the meaning of sentence A is included in sentence B,then we can say that
A.Sentence A is an entailment of sentence B
B.Sentence A entails sentence B
问题解答：
我来补答
选A 啊
A is included in sentence B 说明 B 包含A
那么 Sentence A is an entailment of sentence B 【A是B的一个包含部分】
【定义】
蕴涵 Entailment
Entailment can be illustrated by the following tow sentences in which sentence A entails sentence B.
A:Mark married a blonde heiress.
B:Mark married a blonde.
再问： 定义的A,B没看懂-_-||
再答： A: Mark married a blonde heiress. B: Mark married a blonde. 这里面A 的词数（元素）比B 多，所A 包含(entails)B 【sentence A entails sentence B.】 而B 是A的蕴含项（entailment）【Sentence B is an entailment of sentence A】 【我举的例子和你的题目相反，看清楚了哈】
再问： 怎么解释:I bought a book from Jack. I bought sth. from sb.
再问： 怎么解释:I bought a book from Jack. I bought sth. from sb.
再答： 中文意思？不是吧？
再问： 是前句entails后句？
再答： I bought sth. from sb. 包含了 I bought a book from Jack.
再问： 彻底晕了…吃饭去
