from the above picture ,what the picture illustrates is that
3个回答

what 引导主语从句,illustrates是主语从句中的谓语动词.

而is 是整个句子的动词,它是一个系词.

illustrates与is 分属于两个不同层次的句子中,因此它们并不矛盾,

而且is必不可少,如果去掉is.那么句子就没有动词.它就不是一个完整的句子了.

(后面的that引导表语从句.)

直接说what the picture illustrates that books are very important to us .是不对的,

除非去掉what.(因为 illustrates 后已经跟了宾语从句,那么 what就显得多余了.)

即:The picture illustrates that books are very important to us .
