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。
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
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 are
some books, that you are interested in 和上面那句的形式差不多 也是相当于 books 的定语从句 主体句子就是 you can choose some books
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。
people who read 做主语,所以后面用are .
books 后面省略that
