Alaska’s Arctic lakes now freeze later and melt earlier in the year than in 1950，leaving them easy to suffer water loss from evaporation(蒸发)and possibly adding to local warming，a new study finds．The winter ice season near Barrow，Alaska，is shorter than in 1950，researchers reported Jan.30 in the journal The Cryosphere.
Lake ice is also thinner each winter．The scientists surveyed 402 lakes on the North Slope，where permafrost (permanently frozen ground)and shallow lakes dominate the areA． In 2011，the lake ice was 38 percent thinner than in 1950，and 22 percent fewer lakes froze through to their bottoms．
“When we saw the actual numbers we were shocked at how dramatic the change has been，”lead study author Cristina Surdu，of the University of Waterloo in Canada，said in a statement．Surdu and her co-authors analyzed the changes in lake—ice thickness and ice cover with satellite images and climate model simulations(satellite images are only available from 1991)．
The climate models suggest the Arctic lakes froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared with the winter of 1950．“The changes in ice and the shortened winter affect Northern communities that depend on ice roads to transport goods，”Surdu saiD． For example，every winter，oil companies build roads over frozen lakes to carry supplies to Prudhoe Bay．
“The dramatic changes in lake ice may also contribute to further warming of the entire region，because open water on lakes contributes to warmer air temperatures，”Surdu saiD． The Arctic is warming twice as fast as the rest of the planet，for reasons that may include its layered atmosphere，which traps heat，and the loss of sea ice and snow cover，which help reflect the sun’s energy when present．What does the text mainly tell us?

Did you know that the first documented use of OMG(oh my god)was in 1917, or that LOL was once a common term meaning little old ladies in 1960? That's what the world learned when OMG, LOL, and FYI (for your information) were added to the Oxford English Dictionary last week. This dictionary is considered by many to be the reference book that defines the English language.
Words added to the Oxford English Dictionary are truly considered new members of the language. People invent new words all the time, but only a few become popular enough to get defined in dictionaries.
Typed online or in text messages, LOL, FYI, and OMG are initialisms,_which can be said aloud letter by letter, like LOL, which now stands for Laugh Out Loud.Faster to type than the full phrases, initialisms like these have been used online since the 1990s. But these three online terms are now spoken outside the Internet too, making them different from other online lingo( 行话). Dictionary editors decided the words are used so commonly that they had to be defined this year.
Another important addition to the dictionary this year was ♥， as in “I♥ NY.” This is the first graphic (图形的 ) symbol ever defined in the Oxford English Dictionary.The editors added ♥ as a verb under the definition of “heart”， meaning “to love”．
Some slang words — informal language used more commonly in speech than in writing — were also added, like wassup, a shortened way to say “What's up”. Even words that have been in use for many years like biker and happy camper were finally added to the dictionary.
The Oxford English Dictionary now defines more than 600,000 words.That adds up to more than 21,730 pages! Guinness World Records calls it the longest dictionary in the world.The Oxford English Dictionary is known for recording words of all kinds—popular, outdated, and even foreign words used by English speakers throughout the language's long history.The text is mainly about that ________.
| A．expressions like LOL and FYI have been added to the Oxford English Dictionary |
| B．English words change their meaning as time goes by |
| C．English language is becoming more and more difficult to learn |
| D．the Oxford English Dictionary breaks the Guinness World Record |
Which of the following is NOT included in the facts that the Oxford English Dictionary has been updated?
| A．Some online terms are added to it. |
| B．A graphic symbol is first introduced into it. |
| C．Some slang words are collected in it. |
| D．Some old words are left out. |
What does the underlined word “initialisms” refer to?
| A．Words having foreign origins. |
| B．Words made from the first letters of several words in a phrase. |
| C．Uncommon words frequently appearing on the Internet. |
| D．Official words used in formal documents with capital letters. |
Before any new word is added to the Oxford English Dictionary, it must be ________.
| A．spread widely across the Internet |
| B．used commonly by the dictionary editors |
| C．used commonly in either spoken or written language |
| D．a short word |

Parents are creating an “I want it now” generation by indulging children's every demand at Christmas，say experts.Youngsters are becoming increasingly selfish，claim the education analysts.
Consumersavvy children are forcing their families into racking up huge debts and risk becoming spoilt and dissatisfied in the future.
Behavioural consultant Chris Calland said，“Parents are desperate to make Christmas into a magical fairy tale for their kids.There's nothing wrong with that as such.The problem arises when it means always giving in to all our children's demands—even if they are beyond our price range or not ageappropriate.”
Ms.Calland，who runs “Santa Says No” style sessions with colleague Nicky Hutchinson，added, “Many of us go into so much debt providing the gifts our children want that we spend the rest of the year paying off the bills.Yet so often the parcels we've carefully wrapped，once opened，are just pushed away because the very thing our little boy or girl was once so desperate for, they have now lost interest in.”
Ms. Calland and Ms.Hutchinson have drawn up a list of guidelines to help parents manage their offspring's Christmas lists this year.They say that adults can actually improve their relationships with their children by resisting “pester (纠缠) power”．
Ms.Calland said，“All too often we say yes because we want an easier life when the fact is that we're only building up problems for the future.We are helping create a generation of youngsters who are blind to the needs of others and the necessity of hard work.”
“Children learn fast—if we sometimes change our mind，they quickly realise it might be worth lying on the floor and screaming for it.Make sure you and your partner are working together on this.Be consistent.And try not to get caught up in competition with other families or friends.”How is the “I want it now” generation created?
| A．Parents can't afford the gifts for their children. |
| B．Parents become heavily in debt. |
| C．Parents are trying to make Christmas into a magical fairy tale. |
| D．Parents give children whatever they want at Christmas. |
What is the main problem with the “I want it now” generation?
| A．They are quite selfcentered. |
| B．They like to live in fairy tales. |
| C．They waste a lot of money on gifts. |
| D．They can't keep their interest in gifts. |
What is probably the aim of “Santa Says No” style sessions?
| A．To advise on how to wrap gifts properly. |
| B．To keep children's interest in the gifts. |
| C．To tell parents how to say no to children's demands. |
| D．To advise parents on what gifts to buy for children. |
According to the passage，we can infer that Ms.Calland intends to ________.

All Ric O Barry wants is to stop the dolphinkilling, so he is headed to this seaside Japanese town, Taiji.The American activist, who is the star of a new awardwinning documentary that portrays the dolphinkilling here, got an unwelcome reception when he showed up here this week for the start of the annual hunt.
His movie, The Cove(海豚湾), directed by National Geographic photographer Louie Psihoyos, was released in the United States a month ago but has not yet to come out in Japan.
Scenes in the film, some of which were shot secretly, show fishermen banging on metal poles stuck in the water to create a wall of sound that scares the dolphins— which have supersensitive sonar(声纳系统)—and sends them fleeing into a cove.
There, the fishermen sometimes pick a few to be sold for aquarium shows, for as much as $150,000. They kill the others, spearing(刺) the animals repeatedly until the water turns red. The meat from one dolphin is worth about 50,000 yen, and is sold at supermarkets across Japan.
Greenpeace and other groups have tried to stop the hunt for years.Activists hope The Cove will bring the issue to more people internationally—and eventually in Japan.
Already，the Australian town of Broome dropped its 28year sistercity relationship with Taiji last month，partly because of the movie.
“Some regions have a tradition of eating dolphin meat，” said fisheries official Toshinori Uoya. “Dolphinkilling may be negative for our international image, but it is not something orders can stop.”
The town government in Taiji—which has made whales and dolphins its trademark—refused to comment about The Cove, or the growing international criticism against dolphinkilling.
Many in Taiji take the dolphin hunt for granted as part of everyday life. They are defensive about The Cove，seeing themselves as powerless victims of overseas pressure to end a simple and honest way of making a living.Ric O Barry made The Cove because he wanted to ________.
| A．stop the dolphinkilling |

What is the response to The Cove on the Japanese side?
| A．Taiji broke up with its western sistercity Broome. |
| B．Japanese officials decided to ban dolphinkilling. |
| C．The town government in Taiji kept silent on criticism. |
| D．Most Japanese people were against eating dolphin meat. |
What does the underlined word “defensive” probably mean?
| A．Feeling guilty for killing dolphins. |
| B．Protecting themselves against criticism. |
| C．Attacking those against dolphinkilling. |
| D．Making the determination to change. |
What can we infer from the passage?
| A．Many people in Japan have seen The Cove in the cinema. |
| B．The Cove has not influenced Japan's international image. |
| C．Taiji's dolphinkilling industry has been seriously damaged. |
| D．The Cove has brought international attention to dolphinkilling. |
