学生疑问：(B) A fact is stated, and examples suggesting that a distinction needs correction are considered.(C) A fact is stated, a theory is presented to explain that fact, and additional facts are introduced to validate the theory. 这两句话不太会翻译。其中B里面a distinction needs correction are considered.不会翻译

老师解答：(B) A fact is stated, and examples suggesting that a distinction needs correction are considered. 逗号后面句子的主干是examples are considered, suggesting that a distinction needs correction是examples的后置定语。A fact is stated, a theory is presented to explain that fact, and additional facts are introduced to validate the theory. 陈述一个事实，提出一个理论来解释这个事实，同时引入其它事实来验证这个理论。

点评分析：找动词时，分清哪些是谓语动词，哪些是非谓语动词。B句中如果suggesting是谓语的话，从语法上讲就是错误的，动词ing做谓语的时候前面必须有系动词。
