ll="" grow="" out="" of="" this="" too.Now, though, comes word that high blood pressure can be destructive even in childhood. According to a recent report in the journal Circulation, 19 of 130 children with high blood pressure developed a dangerous thickening of the heart muscle that, in adults at least, has been linked to heart failure. “No one knows if this pattern holds true for younger patients as well,” says Dr. Stephen Daniels, a pediatric cardiologist who led the study at Children s Hospital Medical Center in Cincinnati, Ohio. “But it’s worrisome.”Who’s most at risk? Boys more than girls, especially boys who are overweight. Their heart works so hard to force blood through extra layers of fat that its walls grow more dense. Then, after decades of straining, it grows too big to pump blood very well.Fortunately the abnormal, thickening can be spotted by ultrasound. And in most case, getting that blood pressure under control—through weight loss and exercise or, as a last resort, drug treatment一allows the overworked muscle to shrink to normal size.How can you tell if yours are like the 670,000 American children ages 10 to 18 with high blood pressure? It’s not the sort of thing you can catch by putting your child’s arm in a cuff at the free monitoring station in your local grocery. You should have a test done by a doctor, who will consult special tables that indicate me normal range of blood pressure for a particular child’s age, height and sex. If the doctor finds an abnormal result he will repeat the test over a period of months to make sure the reading isn’t a fake. He’ll also check, whether other conditions, like kidney disease, could be the source of the trouble. Because hypertension can be hard to detect the National Heart, Lung and Blood Institute recommends annual blood-pressure checks for every child over age 3.About half the cases of hypertension stem directly from kids being overweight. And the problem is likely to grow. Over the past 30 years the proportion of children in the U. S. who are overweight has doubled, from 5% to 11 % or 4.7 million kids.You can keep your children from joining their ranks by clearing the junk food from your pantry and hooking you kids—the earlier the better一on healthy, attractive snacks like fruits (try freezing grapes or carrot sticks with salsa). Not only will they lower your children’s blood pressure:these foods will also boost their immune system and unclog their plumbing. Meanwhile, make sure your kids spend more time on the playground than with their Play-Station. Even if they don’t shed a pound, vigorous exercise will help keep their blood vessels nice and wide, lowering their blood pressure. And of course, they’ll be more likely to eat light and exercise if you set a good example.1.The word “unclog” in the last paragraph can be replaced by（ ） .2.By saying “It’s not the sort of thing you can catch by putting your child’s arm in a cuffat the free monitoring station in your local grocery”, the writer implies （ ） .3.Which of the following is not suggested by the writer to control hypertension?4.We can conclude from the passage that（ ）.'>

For years pediaticians didn’t worry much about treating hypertension in their patients. After all, kids grow so fast, it’s hard keeping up with their shoe size, let alone their blood pressure. Sure, hypertension in adults places them at greater risk of heart attack and stroke. But nobody likes the idea of starting youngsters on blood-pressure medicine they could wind up taking the rest of their lives. Who knows what previously unheard-of side effects could crop up after five pr six decades of daily use?The rationale has been: kids grow out of so many things, maybe they'll grow out of this too.Now, though, comes word that high blood pressure can be destructive even in childhood.

Because Johnson, despite the drudgery, knew that language was not harmless. Its power to inform and to lead astray, to entertain and to annoy, to build co-operation or destroy a reputation, makes language serious stuff, The Economist's “Johnson” column began in 1992 and was later revived online. This week it returns to the print edition, and henceforth will appear fortnightly.Many of the topics tackled are fun: swearing and slang, preferences and peeves. Some are more fundamental. Language reveals a lot about human nature: how people reason differently in a foreign language, or to what extent different languages encode a world view, are some of the most exciting and controversial topics in linguistic research.People care intensely about their language, and so language in the wider world sometimes comes into conflict. The perceived arrogance of Castilians to Catalan threatens to sunder Spain; “language police” in Quebec tell restaurant owners to change “pasta” and “grilled cheese” pates and fromae fondant. At the extreme, the passage of a law downgrading Russian in Ukraine helps spark war in that country ; Vladimir Putin has used it as evidence that Ukrainian nationalists are bent on wiping out Russian culture there. The war has rumbled on since, with language the most obvious symbol of wider identity and sympathy.So the Johnson column treats topics light and heavy as well as language both English and international. A language column is expected to tackle questions of right and wrong. There are roughly two views of how to do this: one top-down, based on authority, prestige, writing and stability; one bottom-up, resting on how most people actually use the language, and open to change.The two schools of thought, known as “prescriptivism”( which sets down how the language should be) and “descriptivism” ( which tells how it is ) , have often been at daggers drawn: English teachers and some usage-book writers on one side, and academic linguists, lexicographers and other usage-book writers on the other. In the caricature, prescriptivists are authoritarians with their heads in the sand, insisting on Victorian-era non-rules. The descriptivists are mocked as “anything-is-correct '', embracing every fad, even that Shakespeare should be taught in text-message-speak.An intellectual writing for an elite audience, Samuel Johnson did not shy away from “right” and “wrong”, even “barbarity”, “depravity” and “corruption”, in matters of language. But he declared his task was not to “form” but to “register” (that is, describe) the language; trying to stop change was like trying to “ lash the wind”. Above all, his years of drudging at the dictionary had taught him humility: he knew he was sure to commit “ a few wild blunders, and visible absurdities, from which no work of such multiplicity was ever free”.Prescribing is not really the opposite of describing. Lexicographers from Johnson's day on must describe the language, grounding their definitions in real living English. But that is in order to give stronger roots to a book they know people will use for firm guidance. Academic linguists, the arch-descriptivists, are perfectly willing to call some usages wrong and others plain ugly.1.Which of the following is INCORRECT about Samuel Johnson according to the passage?2.Why is language serious stuff according to the passage?3.From Para 4, the author has listed the conflicts caused by language in the following countries EXCEPT（ ） .4.Which of the following is NOT MENTIONED in the passage?'>
