Two decades is a long time, yet I often tell my friends that it feels like only two years. That is because China is an exciting place to be with lots of opportunities for begetters or those who seek adventure. It so happens that I fall into both categories.At first, I was not sure whether I would like my experience in China, so I initially planned to study for only one year when I left Trinidad for Beijing. But as fate would have it, I fell in love with China, its people, and its culture. I extended my course for another three years to learn all I could about this fascinating country, Being in China has allowed me the rare chance to meet many distinguished people. It has also allowed me to do things which I think I would not otherwise have had the chance to do.Years later, I published my first book, “The Emperor, His Bride and the Dragon Robe. " However, to my unexpected delight, this book was officially presented to China as one of state gifts. My mother, full of exhilaration, told me that it was televised on the local news. To this day, I feel highly honored. Among my to-do list is a musical play for children based on the book. Through this book and the play, I hope to share my love for China and engender in children around the world a similar love for Chinese culture.I believe people should have dreams no matter how big or small. However, most importantly, I believe that people must strive to make more opportunities for themselves to fulfill their dreams rather than wait around for a few opportunities to come along by chance. In this regard, I like to use one of Francis Bacon's quotes: "A wise man will create more opportunities than he finds. ”4.Why does two decades feel like only two years to the author?A.Because he has been seeking for opportunities and strive for his dream.B.Because China is an exciting place with lot of opportunities.C.Because he has many friends who are always with him.D.Because he has a fancy for China its people, and its culture.5.What can we infer from Paragraph 2?A.The author was certain he would fall for the experience in China.B.After studying for four years in China, the author fell in love with it.C.It was rare for the author to meet distinguished people in China.D.Being in China, the author has done things which he couldn't do in his hometown.6.What does the underlined word "engender" in paragraph 3 mean?A.Spread.B.

Clap ham began to wonder if AJ. might be able to solve her problem in the same way the technology recognize people's faces.Now, she says, the open-source Bear ID software can be used and adapted by anyone and could have huge hints for understanding the animals* behaviour and avoiding bear-human encounters.In relation to the technology based on human facial recognition, Ed Miller and his partner Mary Nguyen are the software developers from California who connected with Clap ham in an online forum for conservation technology in late 2024.The pair were looking for photos of bears ”for fun" as a way to learn more about recognition software, and so they connected with Clap ham to offer their expertise （专业学问） in adapting artificial intelligence."The technology Pete using is based on the same software used to recognize humans, n said Miller, who added that human identification is far easier, as there are millions of images the software can learn from.We need lots of images of individual animals to tell the system which bear is which, ” said Clap ham, who explained "deep learning" as the process where the software trains itself to recognize certain bears more accurately with more pictures it gets. Clamshell says Beard currently has an 84 percent accuracy rate. This is especially important, given that a bear will look dramatically different throughout the year as its appearance, especially fur and weight, changes a lot.8.What is Clamp's purpose of catching images of grizzlies?A.To monitor the changes of some specific bears.B.To collect data for facial recognition technology.C.To finish his postdoctoral research.D.To meet his interest in the technology.9.What do we know about Clap ham?A.Clap ham uses Al to track bears.B.Clap ham has been in her behavioral research for about 25 years.C.Clap ham cooperates with others to identify the bears.D.Clap ham majors in software developing at the University of Victoria.10.Why did Ed Miller and his partner contact Clap ham?A.They provided her with their specific knowledge in Al.B.They wanted to know more about Al.C.They were eager to attend the online forum.D.They were using the same Bear ID software.11.What is the purpose of this text?A.To call on more people to protect grizzlies.B.To describe the living habits of grizzlies.C.To introduce the technology used to identify grizzlies.D.To record a friendship between Melanie and her partners.DCalifornia likes to think of itself as the state where the future happens, and in 2008, its voters decided the future was high-speed rail. So they approved a $9 billion bond issue to begin an incredible government infrastructure project： a bullet train connecting San Francisco and Los- Angeles, at a cost of $33 billion.For years, the optimists have imagined Californians will travel quickly, comfortably and environmentally between the state*s two major population centers. The pessimists, meanwhile, have watched the project costs a lot. At last count, the estimates had traveled up to $75 billion, even were still climbing.On Tuesday, Gov. Gavin News om （D ） in his state speech called for the state to transform the project to a less costly rail that would run through the Central Valley, which attracted voters' elsewhere attention,because what happened in California illustrates the fact that any U.S. rail project may take a risk.Distance. In other places of the world, major population centers are much closer to each other. And big cities that are reasonably close together is pretty much an essential condition for high-speed rail, which is why they have it and we don't. Imagine what it would take to build a line from New York City to Los Angeles 一 or to Chicago, Houston or Phoenix.Wealth. Of course, the United States does have a few cities that look ripe for rail. And instead of high-speed rail between these cities, we have the express, which takes eight hours to travel from Washington to Boston. Why haven't we built something better? Because truly high-speed rail needs to travel in a fairly straight line. Building newer, better, straighter rail lines would require the government to buy all the land between Point A and Point B and tear down anything that happened to be in the way. However, what's between Point A and Point B is a great deal of highly valuable real estate that will be very expensive to purchase.California displays all these problems totally. The part of the rail line that was reasonably cheap to build didn't go anywhere near where the people were ； it ran through the Central Valley where land was reasonably cheap and the lobbies wererelatively few.12.In paragraph 1, the author intends toA.prove the point of the passageB.explain a government projectC.introduce a topic for discussionD.present the background information13.What do we know about the bullet train project?A.All people are not in favor of the bullet train project.B.The cost of the project is approximately 75 billion.C.Other states have to risk building their own bullet program.D.The project will make Americans travel rapidly, cozily and environmentally.14.What mainly leads to bullet train program's failure?ernors in California tend to leave the project behind.B.The distance is the main reason to limit the bullet project in America.C.None of cities in America can afford to build a bullet train.D.Bullet train is not as popular as express in America.15.What attitude does the author hold towards the high-speed rail in California?A. Indifferent.B. Neutral.C. Negative.D. Optimistic.其次节（共5小题；每小题2.5分，满分12.5分）依据短文内容，从短文中的选项中选出能填入空白处的最佳选项。

Alibaba Group Holding Ltd, China's largest e-commerce vendor, has officially confirmed it will hold an initial public offering in the United States, the company has announced. The decision will "make [Alibaba] a more global company and enhance the company’s transparency, as well as allow the company to continue to pursue our long-term vision and ideals," according to a company statement sent on Sunday to China Daily. It did not specify which bourse it will choose to float its shares, or give a detailed timetable. Alibaba said that, should circumstances permit in the future, it will work towards toward extending its public status in China’s capital market in order to share its growth with the Chinese people. The company also expressed gratitude towards those in Hong Kong who have supported Alibaba Group, including the Hong Kong Stock Exchange, which shut the door on a potential listing last September. "We respect the viewpoints and policies of Hong Kong and will continue to pay close attention to and support the process of innovation and development of Hong Kong," the statement added. Hong Kong regulators rejected Alibaba's IPO because of the firm's special request to keep a shareholder structure which would have allowed a group of top managers and founders to nominate and control the company's board of directors. The unique requirement went against the exchange's one-share-one-vote principle. The statement puts an end to rampant rumors about Alibaba’s choice of listing venue. For example, the firm's recent purchase of a stake in a Hong Kong-listed company prompted speculation that Alibaba might use the deal to go public. Analysts polled by Reuters have put Alibaba's market value at around $140 billion and the value of the IPO at $15 billion. If successful, it will go public in the world's biggest listing since Facebook Inc's debut in 2012. The announcement came just two days after micro-blogging service Sina Weibo filed to raise $500 million via a US IPO. Alibaba holds 18 percent of Sina Weibo's shares. 【新闻快讯】 阿⾥巴巴集团16⽇宣布，启动在美国的上市事宜。

The assailants stormed the village in cars and motorbikes, a trademark of Boko Haram, the residents ad ded.It came a day after twin bombings killed 122 in the central city of Jos. The authorities suspect Boko Haram of being behind them, but there has so far been no claim of responsibility from the group.'Al-Qaeda training'Boko Haram was added to the al-Qaeda Sanctions Committee's list of designated entities on Thursday at the request of Nigeria."Today, the Security Council took an important step in support of the government of Nigeria's efforts to defeat Boko Haram and hold its murderous leadership accountable for atrocities," Ms Power said.The sanctions designation would help "close off important avenues of funding, travel and weapons" to the group, she added.On Wednesday, Nigeria's permanent representative, U Joy Ogwu, said: "The important thing is to attack the problem, and that is terrorism."The BBC's Barbara Plett Usher in New York says Boko Haram's links with al-Qaeda have come under scrutiny.Reports quoting a draft UN document said its members had received training from al-Qaeda affiliates and fought alongside them in Mali.。

Arm是一家什么样的公司？为什么媒体会用“春天到来”形容它的IPO？Arm Soars 25% in the Year's Biggest Initial Public OfferingBy Erin Griffith and Don ClarkCall it Wall Street's Groundhog Day. When shares of Arm, the British chip designer, began trading on the Nasdaq stock exchange on Thursday in the year's biggest initial public offering, investors, tech executives, bankers and start-up founders were watching closely for how it performed.They quickly got their answer: It was an early spring. Arm's shares opened trading at $56.10, up 10 percent from its initial offering price of $51. Shares quickly soared further, rising 25 percent by the end of trading to close at $63.59 and giving the company a valuation of $67.9 billion.That stands out in a year that has been the worst for I.P.O.s since 2009. Arm is a particularly interesting test of the public market because it provides an essential technology that is geopolitically and strategically coveted, which also means it faces challenges.Founded in 1990 in Cambridge, England, the company sells blueprints of a part of a chip known as a processor core. Its customers include many of the world's largest tech companies, like Apple, Google, Samsung and Nvidia.Arm's chip designs are primarily used in smartphones, but the company has pitched itself as able to ride the wave of artificial intelligence sweeping Silicon Valley. Many A.I. companies need the most advanced computer chips to do the sophisticated calculations required to develop the tech.【词汇过关】请写出下面文单词在文章中的中文意思。

It said the sales would help to meet the "entire daily d ollar requirements" of the three firm s. According to some estimates, they import about $300m worth of oil daily.The rupee bounced back from its record low, rising 2.5% against the US dollar. The Indian currency is one of the worst performers in the world this year.It has declined more than 20% against the US dollar since the start of 2013.Global oil cont r acts are mostly settled in US dollars. As a result, Indian oil firms need to sell rupees to buy US dollars to pay for the imports.The central bank's swap window is expected to take the bulk of their dollar demand away from the foreign-exchange market and help to stem the decline in the rupee.However, some analysts said the centra l bank's move was unlikely to result in a sustained recovery in the currency."The measure is unlikel y to arrest the decline in the Indian rupee with the authorities increasingly trying to find new means to stem the rout in the curr ency," s aid Mitul Kotecha, head of global markets research for Asia at Credit Agricole.。
