почему же так тяжело

The other day one of my fellow graduate students, someone who has been studying Chinese for ten years or more, said to me "My research is really hampered by the fact that I still just can't read Chinese. It takes me hours to get through two or three pages, and I can't skim to save my life." This would be an astonishing admission for a tenth-year student of, say, French literature, yet it is a comment I hear all the time among my peers.

Another problem with looking up words in the dictionary has to do with the nature of written Chinese. [...] In Chinese there are spaces between characters, but it takes quite a lot of knowledge of the language and often some genuine sleuth work to tell where word boundaries lie; thus it's often trial and error to look up a word. It would be as if English were written thus:
FEAR LESS LY OUT SPOKE N BUT SOME WHAT HUMOR LESS NEW ENG LAND BORN LEAD ACT OR GEORGE MICHAEL SON EX PRESS ED OUT RAGE TO DAY AT THE STALE MATE BE TWEEN MAN AGE MENT AND THE ACT OR 'S UNION BE CAUSE THE STAND OFF HAD SET BACK THE TIME TABLE FOR PRO DUC TION OF HIS PLAY, A ONE MAN SHOW CASE THAT WAS HIS FIRST RUN A WAY BROAD WAY BOX OFFICE SMASH HIT.

Whereas modern Mandarin is merely perversely hard, classical Chinese is deliberately impossible. Here's a secret that sinologists won't tell you: A passage in classical Chinese can be understood only if you already know what the passage says in the first place. This is because classical Chinese really consists of several centuries of esoteric anecdotes and in-jokes written in a kind of terse, miserly code for dissemination among a small, elite group of intellectually-inbred bookworms who already knew the whole literature backwards and forwards, anyway. An uninitiated westerner can no more be expected to understand such writing than Confucius himself, if transported to the present, could understand the entries in the "personal" section of the classified ads that say things like: "Hndsm. SWGM, 24, 160, sks BGM or WGM for gentle S&M, mod. bndg., some lthr., twosm or threesm ok, have own equip., wheels, 988-8752 lv. mssg. on ans. mach., no weirdos please."
