English is the most widely-used language in the history of our planet. One in every seven human beings can speak it. More than half of the world’ s books and three-quarters of international mail are in English. Of all languages, English has the largest vocabulary—perhaps as many as two million words—and one of the noblest bodies of literature. Nevertheless, let’s face it: English is a crazy language. There is no egg in eggplant, neither pine nor apple in pineapple and no ham in a hamburger. Sweetmeats are candy, while sweetbreads, which aren’t sweet, are meat. We take English for granted. But when we explore its paradoxes, we find that quicksand can work slowly, boxing rings are square, public bathrooms have no baths in them. And why is it that a writer writes, but fingers don’t fang, grocers don’t groce, and hammers don’t ham If the plural of tooth is teeth, shouldn’t the plural of booth be beeth One goose, two geese—so one moose, two meese If the teacher taught, why isn’t it true that the preacher praught If a horsehair mat is made from the hair of horses and a camel-hair coat from the hair of camels, from what is a mohair coat made If a vegetarian eats vegetables, what does a humanitarian eat In what other language do people drive on a parkway and park in a driveway Ship by truck and send car- go by ship Have noses that nm and feet that smell How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites How can overlook and oversee be opposites, while quite a lot and quite a few are alike How can the weather be hot as hell one day and cold as hell the next You must be shocked at a language in which your house can burn up as it burns down, in which you fill in a form by filling it out and in which your alarm clock goes off by going on. English was invented by people, not computers, and it reflects the creativity of the human race (which, of course, isn’t really a race at all). That is why, when stars are out they are visible, but when the lights are out they are invisible. And why, when I wind up my watch I start it, but when I wind up this essay I end it. Which of the following does this passage mainly talk about
Hunting for a job late last year, lawyer Gant Redmon stumbled across CareerBuider, a job database on the Internet. He searched it with no success but was attracted by the site’’s "personal search agent". It’’s an interactive feature that lets visitors key in job criteria such as location, title, and salary, then E-mails them when a matching position is posted in the database. Redmon chose the keywords legal, intellectual property, and Washington, D. C. Three’weeks later, he got his first notification of an opening. "I struck gold, "says Redmon, who E-mailed his resume to the employer and won a position as in-house counsel for a company. With thousands of career related sites on the Internet, finding promising openings can be time-consuming and inefficient. Search agents reduce the need for repeated visits to the databases. But although a search agent worked for Redmon, career experts see drawbacks. Narrowing your criteria, for example, may work against you: "Every time you answer a question you eliminate a possibility, "says one expert. For any job search, you should start with a narrow concept-what you think you want to do-then broaden it. "None of these programs do that," says another expert. "There’’s no career counseling implicit in all of this." Instead, the best strategy is to use the agent as a kind of tip service to keep abreast of jobs in a particular database; when you get E-mail, consider it a reminder to check the database again. "I would not rely on agents for finding everything that is added to a database that might interest me," says the author of a job-searching guide. Some sites design their agents to tempt job hunters to return. When CareerSite’’s agent sends out messages to those who have signed up for its service, for example, it includes only three potential jobs-those it considers tile best matches. There may be more matches in the database; job hunters will have to visit the site again to find them--and they do. "On the day after we send our messages, we see a sharp increase in our traffic," says Seth Peers, vice president of marketing for CareerSite. Even those who aren’t hunting for jobs may find search agents worthwhile. Some use them to keep a close watch on the demand for their line of work or gather information on compensation to arm themselves when negotiating for a raise. Although happily employed, Redmon maintains his agent at Career-Builder. "Yon always keep your eyes open," he says. Working with a personal search agent means having another set of eyes looking out for you. Which of the following is true according to the text
