Questionsare based on the following passage.
Texting has long been bemoaned (哀叹) as the downfall of the written word, "penmanship for illiterates," as one critic called it. To which the proper response is LOL. Texting properly isn't writing at all. It's a "spoken" language that is getting richer and more complex by the year.
First, some historical perspective. Writing was only invented 5500 years ago, whereas language probably traces back at least 80000 years. Thus talking came first; writing is just a craft that came along later. As such, the first writing was based on the way people talk, with short sentences. However, while talking is largely subconscious and rapid, writing is deliberate and slow. Over time, writers took advantage of this and started crafting long-winded sentences such as this one: "The whole engagement lasted above12 hours, till the gradual retreat of the Persians was changed into a disorderly flight, of which the shameful example was given by the principal leaders and..."
No one talks like that casually-or should. But it is natural to desire to do so for special occasions. In the old days, we didn't much write like talking because there was no mechanism to reproduce the speed of conversation. But texting and instant messaging do-and a revolution has begun. It involves the crude mechanics of writing, but in its economy, spontaneity and even vulgarity, texting is actually a new kind of talking, with its own kind of grammar and conventions.
Take LOL. It doesn't actually mean "laughing out loud" in a literal sense anymore. LOL has evolved into something much subtler and sophisticated and is used even when nothing is remotely amusing. Jocelyn texts "Where have you been?" and Annabelle texts back "LOL at the library studying for two hours." LOL signals basic empathy (同感) between texters, easing tension and creating a sense of equality. Instead of having a literal meaning, it does something-conveying an attitude-just like the -ed ending conveys past tense rather than "meaning" anything. LOL, of all things, is grammar.
Of course no one thinks about that consciously. But then most of communication operates without being noticed. Over time, the meaning of a word or an expression drifts-meat used to mean any kind of food, silly used to mean, believe it or not, blessed.
Civilization, then, is fine-people banging away on their smart phones are fluently using a codeseparate from the one they use in actual writing, and there is no evidence that texting is ruining composition skills. Worldwide people speak differently from the way they write, and texting-quick, casual and only intended to be read once is actually a way of talking with your fingers.
What do critics say about texting? A．It is mainly confined to youngsters.
B．It competes with traditional writing.
C．It will ruin the written language.
D．It is often hard to understand.
