【題目】D

“Just take it easy.” “Don’t be nervous.” “You’re more likely to die in a car wreck on the way to the airport than you are in a plane crash.” These are just some words given to people with a fear of flying. But as Tom Cruise, playing Lt. Daniel Kaffee in the movie A Few Good Men, said, “I get sick when I fly because I’m afraid of crashing into a large mountain. I don’t think Daniel will help.”

But there’s a new application that just may. Today, the VALK Foundation, a Dutch group that’s a partnership between KLM Royal Dutch Airlines and the University of Leiden, launches the app in the US. The VALK Foundation was one of the first centers for research and fear-of-flying treatment in the world and is the organizer of three world conferences on fear of flying.

The foundation said the app, called Flight App VALK, is the first scientifically-developed, web-based treatment for people who suffer from mild to moderate fear of flying.

“The fear of flying application we have created aims to transfer all of the knowledge we have developed through our program into a mobile application that will help ease travelers’ fears,” said Dr. Lucas van Gerwen, director of the VALK Foundation. Dr. van Gerwen is also a psychologist and professional pilot with more than 30 years experience.

The foundation said up to 30% of adults are fearful fliers. The Flight App is designed to help relax passengers before and during flights by educating users about flight safety and turbulence. It explains the sounds and sensations they can expect during departure, flight and landing. And, if a passenger’s flight stress reaches a panic level, they press a special panic button which provides audio and written information to help decrease stress levels. Most importantly, the Flight App can be used during the flight in the airplane mode. Once downloaded, the program does not require Internet connection in the air.

A. It is a group focusing on psychology on the flight.

D. It organizes the world conferences on fear of flying annually.

【3】What is the purpose of Flight App VALK ?

A. To help passengers experience the fear of flying.

B. To teach people the basic knowledge of taking flight.

【題目】D

HONG KONG — In China, the smartphone battle used to be Samsung versus Apple. But not any more .

Over the summer, a Chinese company, Xiaomi, took the No. 1 position in China’s competitive market and became the world’s third-largest phone maker in the process.

Founded in 2010 , Xiaomi was late to the game. But a clever social media strategy and a business plan that emphasized selling services that work on the phone helped Xiaomi build frenzied support from young and trendy Chinese.

With people in China expected to buy 500 million smart phones in 2015 — more than three times as many as will be sold in the United States, Xiaomi is likely to remain its place as one of the most powerful phone makers in the world’s most important market.

Now the company’s founders, who include the Chinese entrepreneur Lei Jun and the former Google executive Lin Bin, hope that status will help them take their brand globally.

Why Xiaomi gained such great success ? The reason partially lies in its fans’ participation. “Xiaomi fans have a high level of organization,” said Li Nan, vice president of the rival Meizu, “They love Xiaomi. It’s a form of idolatry.”

Han Yu, a 24-year-old studying for his master’s degree, is one of those idolaters. He, with tens of thousands of others, helps Xiaomi test its user interface by looking for bugs and offering suggestions. Much of his personal life revolves around Xiaomi. He said he was honored when his suggestion to create a private photo folder was adopted on phones by Xiaomi.

“I really enjoy the sense of participation,” Mr. Han said.

For all its success, Xiaomi’s biggest challenge looms outside China. In 2013, the company hired Hugo Barra, an old friend of Mr. Lin’s from Google, to lead the company’s international expansion. “I would put China No. 1, India two, Indonesia three, then hopefully follow with Brazil and Russia,” he said. “The developed countries with tightly controlled carrier networks are not in the top five.” The countries Lin identifies all have large populations who still have not bought their first smartphone, meaning Xiaomi has a chance.

【1】The passage mainly tells us ______.

A. the competition between Xiaomi and Meizu

B. the cooperation between Xiaomi and Samsung

C. the battle among Smart phone Companies

D. the development and success of Xiaomi

【2】What helped Xiaomi win the support of young and trendy Chinese?

A. Its low price.

B. Its social media strategy and business plan

C. Its fashionable design.

D. Its international promotion

【3】Who takes charge of expanding Xiaomi’s market abroad?

A. Hugo Barra B. Li Nan C. Lei Jun D. Lei Jun

【4】The example of Han Yu is used to ________.

A. tell readers that the youth like to show off

B. prove Han Yu is very intelligent

C. show Xiaomi fans’ participation and devotion

D. introduce the designer of photo folder

【5】Why Xiaomi chooses less developed countries as targeted markets?

A. Because Xiaomi doesn’t have to pay taxes.

B. Because more smartphone may be sold there.

C. Because Xiaomi was invited to develop there.

D. Because the young people there love Xiaomi.
