很简单的英语问题,帮下忙谢谢!People who read are usually more open-minded and rarely bored 这句话中,read是动词啊,为什么用原型呢?谓语动词是后面的are吧?是非谓语啊为什么可以用原型呢?Besides,you can choose some books you are interested in.这句话里choose不是做谓语动词吗?后面为什么可以出现be动词are呢?不是说be动词要做谓语的吗?到底哪个是谓语呢?看了好久都搞不明白啊...想请你们帮帮忙,谢谢啦!

第一句中who read 是定语从句，修饰people。第二句中you are interested in同样是定语从句修饰books 。定语从句的先行词that或which省略了。

who read 是PEOPLE的定语从句，而PEOPLE是复数名词，从句中用WHO代替，read在从句中是谓语动词，故用原型；
谓语动词是后面的are;
choose是谓语动词，这个句子是复合句，you are interested in 是books的定语，是个定语从句，自然需要are；
不管是主句还是从句都需要是完整的，当然有些成分可以省略

people who read 做主语，所以后面用are .
books 后面省略that

People who read are usually more open-minded and rarely bored 这句话中，read是动词的过去式，不是原形；who read是People的定语从句。People who read 是主语从句，谓语用are。
Besides,you can choose some books you are interested in.这句话里choose是做谓语动词，some books you are interested in其中you are interested in是定语从句。

断下句为：People,who read,are usually more ^^who read 作为 people 的定语 read 是动词的过去式 主语就是 people who read 主体其实就是 people 所以是复数 aresome books,that you are interested in 和上面那句...
