Lexile指数とは?

Lexile指数とは、アメリカのMetaMetrics®社が開発した「読解力」および「文章の難易度」を示す指標です。世界165か国以上で活用されているほか、アメリカでは、小学3年生~高校3年生の約半数が、英語能力テストの結果とともにLexile指数の判定を受けています。本は、単語数や難易度、構文の複雑さなどに基づきLexile指数がふられます。

リーディングに適切な本の難易度は、個人のLexile指数を基準にマイナス100Lからプラス50Lまでの範囲です。たとえば個人のLexile指数が1000Lの場合、読書に適した範囲は900L~1050Lになります。この範囲内の本に頻繁に触れることが、英語の読解力向上の一助となります。


自分のLexile指数はどうすればわかる?

LTOEFLの受験経験がある場合は、Reading セクションのスコアで換算することができます (http://www.lexile.com/toefl/)。同様に、TOEICの受験経験がある場合も、TOEICリーディングスコアをLexile指数に換算できます(http://lerg.lexile.com/ja/)。どちらも受験経験がない場合は、各指数のサンプルテキストを読むことで、自分の大まかなレベルを把握することができます。

『Ronald Morgan Goes to Bat』

<サンプルテキスト>
He smacked the ball with the bat. The ball flew across the field. “Good;’ said Mr. Spano. “Great, Slugger!” I yelled. ‘’We’ll win every game. It was my turn next. I put on the helmet, and stood at home plate. “Ronald Morgan,” said Rosemary. “You’re holding the wrong end of the bat.” Quickly I turned it around. I clutched it close to the end. Whoosh went the first ball. Whoosh went the second one. Wham went the third. It hit me in the knee. “Are you all right?” asked Michael. But I heard Tom say, “I knew it. Ronald Morgan’s the worst.” At snack time, we told Miss Tyler about the team.

『Princess Posey and the Next-Door Dog』

<サンプルテキスト>
We have to stop now, said Miss Lee. "It's time for reading." "Ohhh…" A disappointed sound went up around the circle. "Here's what we'll do." Miss Lee stood up. "You are all very interested in dogs. So this week, you can write a story about your own dog or pet. Then you can read it to the class." Everyone got excited again. Except Posey. She didn't have a pet. Not a dog. Not a cat. Not a hamster. "Those of you who don't have a pet," Miss Lee said, "can write about the pet you hope to own someday." Miss Lee had saved the day! Now Posey had something to write about, too. Posey told her mom about Luca's puppy on the way home.

『How Not to Babysit Your Brother』

<サンプルテキスト>
I continued to search. I checked under Steve's bed. Then I checked under my bed. I searched the basement, the garage, and my closet. There was no sign of Steve. This was going to be harder than I thought. Where was Steve hiding? CRASH! Uh-oh, I thought. I heard Buster barking in the kitchen. I ran to see what was going on. When I got there, the dog food bin was tipped over. Steve's head and shoulders were sticking out of the top. Dog food was stuck in his hair, on his clothes, and up his nose. He looked like an alien from the planet Yuck. He giggled as Buster licked some crumbs off his ear.

『A Germ's Journey』

<サンプルテキスト>
Excuse me! Let's blow out of this place! In real life, germs are very small. They can't be seen without a microscope. Rudy forgot to use a tissue. His cold germs fly across the room at more than 100 miles an hour. Whee! I can fly! Best ride ever! A few germs land on Ernie. But skin acts like a suit of armor. It protects against harm. The germs won't find a new home there. Healthy skin keeps germs out. But germs can sneak into the body through cuts, scrapes, or cracks in the skin. Most germs enter through a person's mouth or nose. Rudy's germs continue to fall on nearly everything in the room - including Brenda's candy.

『You’re on Your Way, Teddy Roosevelt』

<サンプルテキスト>
But from his first workout in Wood's Gymnasium he had been determined to control his asthma and illnesses rather than letting his asthma and illnesses control him. And he had. On that hot summer day in August he had proved to himself - and everyone else - that he had taken charge of his own life. In 1876 Teedie - now known as Teddy - entered Harvard College. He was on his own … without Papa. That was all right. "I am to do everything for myself," he wrote in his diary. Why not? He was stronger and in better health than he had ever been. And ready and eager for the adventures and opportunities that lay ahead.

『The Miraculous Journey of Edward Tulane』

<サンプルテキスト>
Edward, for lack of anything better to do, began to think. He thought about the stars. He remembered what they looked like from his bedroom window. What made them shine so brightly, he wondered, and were they still shining somewhere even though he could not see them? Never in my life, he thought, have I been farther away from the stars than I am now. He considered, too, the fate of the beautiful princess who had become a warthog. Why had she become a warthog? Because the ugly witch turned her into one-that was why. And then the rabbit thought about Pellegrina. He felt, in some way that he could not explain to himself, that she was responsible for what had happened to him. It was almost as if it was she, and not the boys, who had thrown Edward overboard.

『Moon Over Manifest』

<サンプルテキスト>
There wasn't much left in the tree fort from previous dwellers. Just an old hammer and a few rusted tin cans holding some even rustier nails. A couple of wood crates with the salt girl holding her umbrella painted on top. And a shabby plaque dangling sideways on one nail, FORT TREECONDEROGA. Probably named after the famous fort from Revolutionary War days. Anything else that might have been left behind had probably been weathered to bits and fallen through the cracks. No matter. I'd have this place whipped into shape lickety-split. First off, I picked out the straightest nail I could find and fixed that sign up right. Fort Treeconderoga was open for business.

『We Are the Ship: The Story of Negro League Baseball』

<サンプルテキスト>
Rube ran his ball club like it was a major league team. Most Negro teams back then weren't very well organized. Didn't always have enough equipment or even matching uniforms. Most times they went from game to game scattered among different cars, or sometimes they'd even have to "hobo" - which means hitch a ride on the back of someone's truck to get to the next town for a game. But not Rube's team. They were always well equipped, with clean, new uniforms, bats, and balls. They rode to the games in fancy Pullman cars Rube rented and hitched to the back of the train. It was something to see that group of Negroes stepping out of the train, dressed in suits and hats. They were big-leaguers.

『Mythbusters Science Fair Book』

<サンプルテキスト>
There may be less bacteria on the food that's picked up quickly, but playing it safe is the best idea. If it hits the floor, the next thing it should hit is the trash. If putting together petri dishes and dealing with incubation seems like a bigger project than you're ready to take on, there's a simpler way to observe bacterial growth. Practically all you need is some bread and your own two hands. Cut the edges off each slice of bread so that they'll fit into the plastic containers. Put one slice of bread into each container. Measure one tablespoon of water and splash it into the first piece of bread. Put the lid on the container and use your pen and tape to label this your control.

『Pride and Prejudice』

<サンプルテキスト>
Lydia was a stout, well-grown girl of fifteen, with a fine complexion and good-humoured countenance; a favourite with her mother, whose affection had brought her into public at an early age. She had high animal spirits, and a sort of natural self-consequence, which the attentions of the officers, to whom her uncle's good dinners and her own easy manners recommended her, had increased into assurance. She was very equal therefore to address Mr. Bingley on the subject of the ball, and abruptly reminded him of his promise; adding, that it would be the most shameful thing in the world if he did not keep it. His answer to this sudden attack was delightful to their mother's ear.

『Why We Can't Wait』

<サンプルテキスト>
We sing the freedom songs today for the same reason the slaves sang them, because we too are in bondage and the songs add hope to our determination that “We shall overcome, Black and white together, We shall overcome someday.” I have stood in a meeting with hundreds of youngsters and joined in while they sang “Ain’t Gonna Let Nobody Turn Me ‘Round.” It is not just a song; it is a resolve. A few minutes later, I have seen those same youngsters refuse to turn around from the onrush of a police We sing the freedom songs today for the same reason the slaves sang them, because we too are in bondage and the songs add hope to our determination that “We shall overcome, Black and white together, We shall overcome someday.”

『1776: America and Britain at War』

<サンプルテキスト>
But from this point on, the citizen-soldiers of Washington's army were no longer to be fighting only for the defense of their country, or for their rightful liberties as freeborn Englishmen, as they had at Lexington and Concord, Bunker Hill and through the long siege at Boston. It was now a proudly proclaimed, all-out war for an independent America, a new America, and thus a new day of freedom and equality. At his home in Newport, Nathanael Greene's mentor, the Reverend Ezra Stiles, wrote in his diary almost in disbelief: Thus the Congress has tied a Gordian knot, which the Parl [iament] will find they can neither cut, nor untie. The thirteen united colonies now rise into an Independent Republic among the kingdoms, states, and empires on earth…. And have I lived to see such an important and astonishing revolution?

『Nathaniel's Nutmeg』

<サンプルテキスト>
Setting sail once again they kept a sharp look-out for Busse Island, discovered thirty years previously by Martin Frobisher, but the rolling sea mists had grown too thick. Storms and gale - force winds plagued them for days on end and at one point grew so ferocious that the foremast cracked, splintered and was hurled into the sea. It was with considerable relief that the crew sighted through the mist the coast of Newfoundland - a vague geographical term in Hudson's day - at the beginning of July. They dropped anchor in Penobscot Bay, some one hundred miles west of Nova Scotia.

『Don Quixote』

<サンプルテキスト>
The Words were to me so many Pearls of Eloquence, and his Voice sweeter to my Ears than Sugar to the Taste. The Reflection on the Misfortune which these Verses brought on me, has often made me applaud Plato's Design of banishing all Poets from a good and well governed Commonwealth, especially those who write wantonly or lasciviously. For, instead of composing lamentable Verses, like those of the Marquiss of Mantua, that make Women and Children cry by the Fireside, they try their utmost Skill on such soft Strokes as enter the Soul, and wound it, like that Thunder which hurts and consumes all within, yet leaves the Garment sound. Another Time he entertained me with the following Song.

『Sustaining Life: How Human Health Depends on Biodiversity』

<サンプルテキスト>
Pregnant Polar Bears can den for as long as nine months. The reason bears are able to achieve this seemingly impossible biological feat is that they are able to recycle the calcium that is lost from bone back into forming new bone. Ralph Nelson and his laboratory at the Carle Foundation Hospital and the University of Illinois College of Medicine at Urbana Champaign have isolated an extract from denning bears that inhibits the activity of osteoclasts, the cells that are involved in the normal process of bone breakdown, and stimulates cells called osteoblasts that form new bone, and others called fibroblasts that form new cartilage. This extract has also been shown to reverse bone loss in rats that had their ovaries removed, simulating a postmenopausal state in humans.
