【题目】A
BEIJING — Rising smartphone star Xiaomi is moving upmarket and taking aim at Apple’s iPhone. The Chinese maker known for low-priced phones on Thursday unveiled (发布) a new model that Chairman Jun Lei said is comparable to Apple’s iPhone 6 but thinner, lighter and much cheaper. The phone starts at 2, 299 yuan ($375), less than half the 5,288 yuan ($ 865) price of an iPhone 6 in China.
Xiaomi, founded in 2010, passed South Korea’s Samsung Electronics Co. in the second quarter of last year as the best-selling smartphone brand in China by the number of phones sold. The company is expanding into India and other developing markets but has yet to announce plans to enter the United States or Europe.
Xiaomi "is a respected brand that already has an Apple-like following" in China, said analyst Brian Blair, who tracks mobile device makers at Rosenblatt Securities. Apple is still a relatively small player in China, selling about 45 million iPhones there last year, Blair estimates, but will continue to grow.
"Apple is very much a premium (高端的) brand," said Blair. "The company that’s more at risk is Samsung, which has been losing share in that market."
Privately-held (私人控股的) Xiaomi said last year’s sales tripled to 61.1 million phones and revenue (收益) more than doubled to 74.3 billion yuan ($12.2 billion). The company, based in Beijing, recently completed a round of fundraising from investors that it said valued Xiaomi at $ 45 billion, making it one of the world’s most valuable technology brands.
Xiaomi ran into legal trouble in India in December after a court blocked sales while it hears a complaint by Sweden’s LM Ericcson that the Chinese company violated its patents(专利).
In a blog post earlier this month, Lei called the case a "rite of passage" (成年礼) for a young company.
【1】Which of the following statements is true?
A. Xiaomi sold more cellphones than Samsung in 2010 in China.
B. Compared to Xiaomi, Apple’s iPhone 6 is thinner and lighter.
C. Low price is Xiaomi’s advantage over Apple’s iPhones.
D. The company is expanding into the United States or Europe.
【2】 What can be inferred from the passage according to Brian Blair?
A. More than 45 million iPhones will be sold this year.
B. Xiaomi can beat Apple in the market of China.
C. He thinks Xiaomi is superior to Apple.
D. Samsung will be closed for losing share in the market.
【3】How is the 5th paragraph developed?
A. By giving examples.
B. By analyzing cause and effect.
C. By providing data.
D. By making comparisons.
【4】What’s the attitude of Jun Lei towards the case of Xiaomi in India?
A. Negative. B. Satisfied. C. Positive. D. Doubtful.

【题目】B
Wong Fuk-wing, a Hong Kong volunteer(志愿者) at an orphanage(孤儿院) in Yushu, was killed in the earthquake when he was trying to save others on April 14, 2010.
Wong managed to run safely out of the building with some children when the first quake happened at 7:50 am on April 14, but he went back inside to rescue three other children and three teachers inside, although he knew the danger of aftershocks(余震).
At 10 a. m., all the children and one of the teachers were saved. However, Wong was buried under the fallen building and died. The other two teachers were still waiting to be rescued.
46-year-old Wong was a truck driver, who often said he could only give his efforts to charity(慈善) instead of money, as he did not earn a lot. His tragic(悲剧的) end touched the hearts of many people both in Hong Kong and on the mainland.
Wong began volunteering in 2002. In 2003, Wong was told by the doctor he got serious illness, which gave him a great blow. However, the illness did not deter the warm-hearted man. When the earthquake struck Wenchuan in Sichuan Province in 2008, Wong rushed to the disaster area of Shifang to offer his help though his family did not want him to go.
In fact, Qinghai is a place Wong had often visited since 2006. As a volunteer, he gave out medicine and clothing to the orphanage there. No one could expect that Wong would die helping others.
Hong Kong Chief Secretary Henry Tang Ying yen said he had "the highest respect" for the hero who gave his life for others. "What he did has shown the Hong Kong spirit." The citizens of Hong Kong called him "the pride of Hong Kong’s people" and people on the mainland have also praised him as "a true hero".
【1】Wong died in the earthquake ____________.
A. after he sent medicine and clothing to the orphanage
B. when he returned to save the teachers and students
C. because he suffered from his serious illness again
D. as the first earthquake happened
【2】The underlined word "deter" in Paragraph 5 refers to "____________".
A. prevent B. refuse C. kill D. encourage
【3】What can we know about Wong from the passage?
A. He never visited Qinghai before 2010.
B. He was supported by his family being a volunteer.
C. He was thought highly of by the Chinese.
D. He was a taxi driver before he died.
【4】Which of the following words can be used to describe Wong according to the passage?
A. Honest and self-satisfactory.
B. Warm-hearted and selfless.
C. Proud and self-centered.
