我认为,主语是rocks.所以has应该改为have

佐儿

yup,同上

shiran

我觉得应该是has been。

flywood

我觉得是HAVE ORGINATED,因为他的主语是复数,中间的那些是混淆事项,一般这样的时候都是跳过这些先看主干成分.

答案是C
has originated --> have been originated


主语是 rocks ，are 和 have 在句中为并列谓语，其中as is implied by the name 为插入语，可以不理之，这样就比较好看出来了。后面有by ,若不是固定搭配，谓语应该用被动形式。


个人意见，仅供参考。

= As is implied by the name, most aggregate rocks are fused and are originated by the aggregation of smaller stones.


that is a fact.     so, using present tense.        the    paralle structure:         rocks are ... and are ....
