Please translate the following paragraph into Chinese. Students aren't what they used to be. These days, it seems, some of them never even open a book. Such is the depressing picture painted by popular science writer Steve Jones in his book The Single Helix, laying the finger of blame on modern communication systems. The message is the medium; once upon a time there were books, but now, Jones says, "the medium is, or so it seems, anything but lines of print on a page.” Many students are just not used to reading books anymore – they're such an outdated form of communication.
