原文：Andanothermystery-someoftheseunrealisticanimals-thatsintheengravings-seemtobehalfhuman.

老師， that is in the engravings 這句話是someoftheseunrealisticanimals這句話的從句嗎， 若是，為何不需要that are

And another mystery - some of these unrealistic animals - thats in the engravings - seem to be half human.

紅色部分是定語從句，應(yīng)為：which arein the engravings.

去掉破折號(hào)，全句的結(jié)構(gòu)是：

And another mystery is that some of these unrealistic animals which are in the engravings seem to be half human.

另一個(gè)謎團(tuán)是，這類雕刻上的虛假的動(dòng)物好像是半人半獸。
