Today, several of the world's nearly 7,000 languages face a serious risk of extinction. "For example, Ainu, a language in Japan, is now seriously threatened, with only 10 native speakers left," said lead study author Tatsuya Amano at the University of Cambridge in England.

The scientists found that 25 percent of the world's languages are threatened. After identifying where the endangered languages were, they looked for any environmental and social or economic factors those languages might have in common, such as rugged terrain or rapid population growth. "We found that at the global scale, language speaker declines are strongly linked to economic growth-that is, declines are particularly occurring in economically developed regions," Amano said.

One important implication of this new study "is that languages in the tropics and Himalayan region are likely to be increasingly threatened in the near future, because these regions still have many local indigenous languages (土語) with a small number of speakers, and at the same time are experiencing rapid economic growth," Amano said.

Economic growth may endanger languages for a variety of reasons. For instance, speakers of endangered languages may view another more dominant language as offering economic opportunities, and thus forego their own languages. There are other important factors that might endanger languages, the researchers said. For instance, policies regarding how languages are used and taught in schools can be very different among countries and even within each country, and these factors may explain more detailed patterns in language endangerment.

Amano suggested it could be possible to forecast future threats to linguistic diversity. "There exists detailed information on projected future changes in the environment, economies and climates," Amano said. "Using such information, together with the findings of this study and further analysis, we would like to understand what will happen to the world's languages, where it will happen and which languages will be threatened in particular."

1.The language of Ainu is mentioned in Paragraph l in order to tell us that _______________.

A. Japanese is new seriously threatened

B. few people speak Japanese in the world

C. Japanese is made up of many languages

D. it is most likely to disappear in the future

2.What may endanger the languages most according to Amano?

A. The diversity of society.

B. The decline of the population.

C. The development of economy

D. The improvement of the environment.

3.The writer shows us the reasons that languages are endangered by ___________________.

A. offering some examples

B. performing some experiments .

C. telling some interesting stories

D. making a list of important facts .

4.It can be inferred from the last paragraph that _______________.

A. the study is very important to languages

B. world's languages are developing rapidly

C. it is rather hard for us to protect languages

D. future threats to languages can be predicted

Success is often measured by the ability to overcome adversity（逆境）. But it is often the belief of others that gives us the courage to try.

J. K. Rowling, author of the Harry Potter book series, began writing at age 6. In her biography（傳記）, she remembers with great fondness when her good friend-Sean became the first person to encourage her and help her build the confidence that one day she would be a very good writer.

“He was the first person with whom I really discussed my serious ambition（志向） to be a writer. He was also the only person who thought I was bound to（注定）be a success at it, which meant much more to me than I ever told him at the time.”

Though there were many difficulties, Rowling continued her writing, particularly fantasy stories. But it wasn’t until l990 that she first came up with the idea about Harry Potter. As she recalls（回憶）, it was on a long train journey from London to Manchester that “the idea of Harry Potter simply fell into my head. To my great disappointment, I didn’t have a pen with me, and I was too shy to ask anybody if I could borrow one. I think, now, that this was probably a good thing, because I simply sat and thought, for four (delayed train) hours, and all the details came up in my brain, and this thin, black-haired, bespectacled（戴眼鏡的）boy who didn't know he was a wizard became more and more real to me.”

That same year, her mother died after a ten-year fight with serious diseases, which deeply affected her writing. She went on to marry and had a daughter, but separated from her husband shortly afterwards.

During this time, Rowling was diagnosed with depression（診斷患有抑郁癥）. Unemployed, she finished her first novel in area cafes, where she could get her daughter to fall asleep. After being refused by l2 publishing houses, the first Harry Potter novel was sold to a small British publishing house.

Now with seven books that have sold nearly 400 million copies in 64 languages, J. K. Rowling is the highest earning novelist in history. And it all began with her friend’s encouragement as well as her ambition to write.

1. Who believed J. K. Rowling was to be a good writer?

A．Her friend Sean. B．Her mother.

C．Her daughter. D．Her husband.

2.Rowling first came up with the idea about Harry Potter________.

A．a(chǎn)t the age of 6 B．on a train journey

C．a(chǎn)fter her mother’s death D．in her secondary school

3.She felt disappointed on the train because_________.

A．her train was delayed for four hours

B．she didn’t have a pen with her

C．her mind suddenly went blank

D．no one would offer her help

4.It can be concluded from Paragraph 5 and 6 that Rowling is_________.

A．open-minded B．warm-hearted

C．good-natured D．strong-willed

5.The text mainly tells us_________.

A．a(chǎn)dversity makes a good novelist

Last Thursday, Michael and Linda stood behind large food trucks distributing meals to 4,000 homeless people for their wedding reception on the border town of Kilis. The couple had decided that instead of hosting their friends and family for a traditional feast reception, they would feed the victims from an earthquake-stricken area.

The idea came from the bridegroom's father, Ted, who volunteers for a Turkish relief organization. For the past few years, the organization has distributed daily meals to thousands of people who've suffered from natural disasters. He approached a representative of the organization and suggested that the family cover part of the costs of feeding them for the day.

Then he told his son, who was surprised by the suggestion, but soon won over. When he told that to the bride, she was really shocked but finally accepted because in southeastern Turkey there is a real culture of sharing with people in need. They love to share their food, their table and everything they have. And afterwards she was quite amazed about it. So, they arrived at the distribution center on Thursday to spend the day serving food and taking photographs with their grateful recipients（接受者）．

On Tuesday evening, the newly married couple were still pleased with their decision to quit a personal celebration for one with a greater good. "It's like sharing a dinner with your friends and family who have this kind of thing on a daily basis or sharing something with people who don't even have the most basic things," Michael said. "Hopefully, this will also give the start for other wedding dinners to be held here with our brothers and sisters in need."

1.Why did so many people crowd in Kilis?

A. To attend Michael and Linda's wedding.

B. To support the organization.

C. To escape the damaging earthquake.

D. To help distribute free daily meals.

2.How did the couple celebrate their wedding?

A. They treated their friends and relatives to a big dinner.

B. They shared their happiness with the homeless in Kilis.

C. They afforded the entire cost of the day for feeding victims.

C. came across D. consulted with

4.We can know from the text that __________________..

Barack Obama has really gone wild. The US president has taken part in the survival television show Running Wild With Bear Grylls, which will air on NBC later this year. In the show, Obama goes on an adventure with host Bear Grylls, learning how to survive in the Alaskan wilderness.

Although he is far from the White House kitchen, Obama seems to enjoy the outdoors. “As president, I am in what’s called the bubble（保護(hù)膜）, and the Secret Service makes sure that I’m always out of danger... but I sometimes want to get out,” he said in a video.

In order to help customers find what they want quickly，it’s important to keep the thousands of titles in the Main Street Movies store organized properly．This section of the Employee Handbook will tell you how to organize videos.

Each Main street Movies store has three main sections:

1.New Releases Wall.

2.Film library.

3.Video Games.

New Releases Wall．Almost 70 percent of movie rentals are new releases，and that is the first place where most customers go when they enter the store．The center section of shelves on this wall holds Hottest Hits．When new titles come into the store，place them on this wall in alphabetical order．The shelves beside Hottest Hits are called Recent Releases．The New Releases Wall，including the Hottest Hits and Recent Releases shelves，holds about 350 titles.

Film Library．The thousands of titles in the Film Library are organized into categories．The films within each category are displayed alphabetically．Here are the categories and their two-letter computer codes：

Foreign Language titles include films that were originally made in a foreign language and films with foreign language subtitles．A sticker on the back of each box tells which type of film it is.

Video Game．All the video games in Main street Movies are arranged in alphabetical order．Although video games represent only a small percentage of our inventory(庫存)，they are stolen more often than any other type of goods in our store．Therefore，video games are never displayed on the shelves．Shelves in the Video Game section hold cardboard with pictures and information about each game．When a customer wants to rent a particular game，you then find the game from the locked case behind the counter.

1.Whom do you think this passage is most probably addressed to?

A． The readers in the store.

B． The manager of the store.

C． The customers in the store.

D． The salespersons of the store.

C． From Recent Releases to Film Library to Hottest Hits.

D． From Hottest Hits to Recent Releases to Film Library.

3.Why can’t video games be seen on the shelves?

A． Because they’ve been sold out.

B． Because they’re in the storehouse.

C． Because they’re in a locked case behind the counter.

D． Because they represent a small percentage of the inventory.

4.How can a customer find a film with foreign language subtitles?
