Not so long ago, it was the stuff of nightmares: you pick up the landline telephone and th

eres no dialing tone. Nothing. The phone is useless,【C1】______in your hand. For most of the 20th century, this was a horror film stereotype, a symbol of isolation and【C2】______foretold. But just 15 years later, the death of the landline is close to being a【C3】______—and one entirely of our own making. BT has announced plans to【C4】______charges for landline calls, in a bid to maintain commercial feasibility for landline services. The move suggests that BT—which has long【C5】______landlines over mobile calls—may have given up on turning back the clock. In the US, the【C6】______of households that have mobile phone connection but no landline has risen to a quarter. The most recent research in the UK, put the【C7】______figure at 15%. For millions of todays twentysomethings, who have had a mobile number since their teens and for whom a landline makes no【C8】______sense during the transient years before they settle down, the moment of【C9】______into land-line-owning may never come【C10】______it becomes an expensive extra. The death of the landline has gone almost unnoticed. After all, the noise of phone chatting is all around us. What【C11】______does it make whether the cables lie underground or not？ A lot,【C12】______. The death of the landline is a cultural【C13】______that affects our personal and public lives. It has separated us【C14】______our groupings—in the office, where email has disconnected us from what the people who sit three feet away do all day, and even more【C15】______, at home. In any household in the days before mobiles【C16】______, the landline served as a switchboard for everyones connections outside the home.【C17】______families, couples, roommates, it was a kind of【C18】______knowledge map about the state of everyones romantic and social lives, and one we took for granted. And【C19】______though we are to our mobiles, most of the time we arent talking but typing. With its arrogant "ignore" button, we all become a little more untouchable in our individual worlds, and less【C20】______.

For many people today, reading is no longer relaxation. To keep up their work they must re

ad letters, reports, trade publications, interoffice communications, not to mention newspapers and magazines: a never-ending flood of words. In【C1】______a job or advancing in one, the ability to read and comprehend【C2】______can mean the difference between success and failure. Yet the un fortunate fact is that most of us are【C3】______readers. Most of us develop poor reading habits at an early age, and never【C4】______them. The main deficiency【C5】______in the actual stuff of language itself—words. Taken individually, words have【C6】______meaning until they are strung together into phrases, sentences and paragraphs.【C7】______, however, the untrained reader does not read groups of words. He laboriously reads one word at a time, often regressing to【C8】______words or passages. Regression, the tendency to look back over【C9】______you have just read, is a common bad habit in reading. Another habit which【C10】______down the speed of reading is vocalization—sounding each word either orally or mentally as one reads.

To【C11】______these bad habits, some reading clinics use a device called an【C12】______, which moves a bar(or curtain)down the page at a predetermined speed. The bar is set at a slightly faster rate【C13】______the reader finds comfortable, in order to "stretch" him. The accelerator forces the reader to read fast,【C14】______word-by-word reading, regression and sub-vocalization, practically impossible. At first【C15】______is sacrificed for speed. But when you learn to read ideas and concepts, you will not only read faster,【C16】______your comprehension will improve. Many people have【C17】______their reading skill drastically improved after some training.【C18】______Charlie Au, a business manager, for instance. His reading rate was a【C19】______good 172 words a minute【C20】______the training; now it is an excellent 1,378 words a minute. He is delighted that he can get through a lot more reading material in a short period of time.

Are passwords outdated？ Its starting to seem like it. Everybody hates them, and nobody can

remember all the ones theyve【C1】______. These days a typical internet user has dozens of online accounts. If you really want to be safe, you need to have a different password for each one, and each password needs to be incredibly【C2】______, with a mix of capital letters,【C3】______, and numbers. Who can keep all that stuff in their head？ Most people dont【C4】______. Some just make up one password and use it everywhere while others might have a few passwords for different usages. Problem is that【C5】______one site gets attacked by hackers, they now have the password that you use elsewhere. In one recent attack on Sony, millions of accounts were exposed. Computer scientists realize the system is【C6】______and theyre looking for alternatives. But most【C7】______havent been very good. Fingerprint readers require special hardware, and smart cards can be lost or【C8】______. "Weve tried【C9】______other approaches, but we end up back with passwords. Theyre the least【C10】______in a series of bad options," says a security consultant. Markus Jakobsson, a veteran security researcher with a Ph.D. in computer science, has come up with something he calls "fastwords." Instead of【C11】______a meaningless and obscure password, you join three simple words that come from a【C12】______known only to you. If one day you were driving to work and【C13】______a frog that ended up flat, you might choose "frog work flat." Some【C14】______: You can enter the three words【C15】______any order ("flat frog work"), and the system【C16】______knows that youre you. If you totally【C17】______, the fastword system will tell you one of the three words, which should enable you to remember the【C18】______idea and thus the three keywords. Jakobsson says one large service provider is evaluating the fast-words concept. Fastwords【C19】______a step in the right direction, 【C20】______its not the promised land. Someone, somehow, needs to come up with something completely different— and radically better—than what we have today.
