21、The sky turned orange and the hospitals were in chaos. Thousands of Iraqis came to emergency rooms complaining that they could not breathe. Some had to be put on respirators. Schools closed and airports cancelled flights. Life came to a stop amid a cloud of dust.
Such scenes have occurred almost weekly in Iraq since April. In decades past, two or three big sandstorms were expected every year. This spring, Iraq has already recorded at least eight. Sandstorms have always been a fact of life in the Middle East, and are now growing more frequently and intensely.
Scientists say dust storms are complex and poorly understood, but their main causes are natural. In 2015, some people blamed a fierce summer storm in the Levant on Syria’s civil war thinking that military vehicles travelling through fields kicked up enough dust to blanket the region. Researchers at Princeton University later cited a more ordinary mix of unusual heat and strong winds as its reason, not gunners.
Still, people plainly contribute to the problem. Demand for water is making a dry region even drier. A World Bank study in 2019 found that human actions, such as over-exploiting rivers and lakes, produce a quarter of the Middle East’s dust. Iran has drained wetlands for farming. Turkish dams on the Tigris and Euphrates mean drier riverbeds downstream. All of this means more dust needs to be swept up by the wind. The decrease of the region’s forests because of fires and cutting down trees means there is less vegetation to hold it back. Syria, for example, has lost an estimated 25% of its woodland and since 2001, most of it to summer fires. Climate change will make the problem worse.
For those who work outside, sandstorms make life unbearable. Sandstorms bring tiny particles that travel deep into the lungs. The World Bank estimates that air pollution causes 30,000 premature deaths a year in the Middle East — and rising.
Economic costs will mount, too. Workers stay at home. Crops are buried under dust. The UN puts the direct economic cost in the Middle East at $13 bn a year, with indirect costs many times bigger.
【1】What do the scenes described in Paragraph 1 show?
A．The seriousness of sandstorms in Iraq.
B．The high frequency of sandstorms in Iraq.
C．The steps taken to address Iraq’s sandstorms.
D．The Iraqis’ negative response to sandstorms.
【2】How does Paragraph 3 mainly develop?
A．By offering analyses.
B．By giving an example.
C．By providing research results.
D．By challenging a general view.
【3】What does the underlined part “All of this” in Paragraph 4 refer to?
A．A drier climate.
B．Water shortage in the Middle East.
C．The impact of human activities on water resources.
D．Decrease of forest areas across the Middle East.
【4】What’s the author’s attitude towards the Middle East’s sandstorm problem?
A．Puzzled.
B．Worried.
C．Doubtful
D．Optimistic.
22、Algorithms (计算程序) are able to do a huge number of tasks, and the number of tasks that they are able to do is expanding practically every day. According to a new study, despite increasing concern over the effect of algorithms in daily life, more and more people nowadays are willing to trust a computer program, especially if a task becomes too challenging. From choosing the next song on your playlist to choosing the right size of pants, people are relying more on the advice of algorithms to help make everyday decisions.
During the study, researchers asked volunteers to count the number of people of a crowd in a photograph and supplied suggestions that were offered by a group of other people and suggestions offered by an algorithm. As the number of people in the photograph expanded, counting became more difficult and people were more likely to follow the suggestions offered by an algorithm rather than count themselves or follow the “wisdom of the crowd”.
One of the common problems with AI is when it is used for awarding credit. While that is a subjective decision, there are lots of numbers there, like income and credit scores. Therefore, people feel like this is a good job for an algorithm. But we know that dependence leads to unfair and incomplete practices in many cases because of social factors that aren’t considered.
Facial recognition and hiring algorithms have come under inspection in recent years because their use has shown cultural prejudice in the way they were built, which can cause inaccuracies when matching faces to identities or screening for qualified job candidates. The prejudice may not be present in a simple task like counting, but their presence in other trusted algorithms is a reason why it is important to understand how people rely on algorithms when making decisions.
“The eventual goal is to look at groups of humans and computers making decisions and find how we can get them to trust each other and how that changes their behaviors,” one of the researchers said. “Because there is very little research in that setting, we’re starting with the fundamentals.”
【1】What can we learn about the present people from paragraph 1?
A．They become more dependent on algorithms.
B．They show little concern about algorithms in life.
C．They are addicted to numbers of challenging tasks online.
D．They never rely on computers to make everyday decisions.
【2】Which is the disadvantage of algorithms according to paragraph 3?
A．They cannot be used to award credit.
B．They can lead to one-sided decisions.
C．They can give away candidates’ identities.
D．They cannot be applied to difficult calculations.
【3】Why does facial recognition get inspected?
A．It leads to cultural differences.
B．It may produce some false results.
C．It takes lots of money and manpower.
D．It rules out most qualified job candidates.
【4】What message does the author mainly convey in the text?
A．It is really necessary to stay away from AI.
B．It is very easy to make choices with the help of AI.
C．People need to adapt to the development of computers.
D．People tend to trust computer programs more than themselves.

24、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 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.
