文学艺术与媒体是一对难舍难分的孪生子。

Literary art and medium are just like twins.

这对孪生子非常相象，我根本没辩认出谁是谁。

The twins are so much alike that I never knew which is which.

孪生子中一位开赴实行天外观光，其飞翔速率亲近光速，而他的昆玉留在地球上。

Twins in one of space travel, its speed sailing close to the speed of light, and his brother to stay on Earth.
