两个英语题目（even的用法）
1._____allowing for his age,he still acts very immaturely.
A.But B.Yet C.Although D.Even
2.Most people hate rock music.______ I am not by nature an unreasonable or biased person,two vivid and striking personal experiences of rock music during the past two weeks persuaded me that it has become a duty for those of us with enough common sense to see its potential dangers to point them out.
A .If B .While C .When D .Even
第一题选D 第二题选B .
第一题even意思为“尽管”,不选Although,是不是Although后面只用接句子；
第二题是让步状语从句,要是有选项Even though也行吧 ,那even和even though做“尽管”意思时的用法区别
还有even（that） 的用法,
第二题为什么even不对？
