Since 1970, North America has lost more than 2.9 billion birds, according to a study recently published in the journal Science. In less than half a century, the bird population has declined by some 29 percent, or more than 1 in 4 birds. For the first time, researchers have discovered that rare species aren't the only birds suffering population loss. In fact, common birds-including beloved backyard friends like sparrows and blackbirds-are taking the biggest hit.
The new study used nearly 50 years of data collected largely by bird watchers and citizen scientists. "A total of 419 native migratory species experienced a net loss of 2.5 billion individuals," the study says. More than 90 percent of the total loss can be found among just 12 bird families. Some of these widespread birds can thrive almost anywhere. The large-scale loss of these hardy birds reveals they're struggling to survive throughout the world/
Birds are considered indicator species because they're crucial to ecosystems, and their populations anticipate the environment's health. Birds are "amazingly efficient" at spreading seeds. Birds also keep insect populations in check. Even the smallest bird helps control the spread of plants or insects.
The new study, however, identifies the losses without knowing all the causes. Scientists do identify habitat loss as the biggest challenge. Climate change, disrupted migration patterns and pesticide use are also major factors. Industrial agriculture may present a bigger challenge. The species disappearing most rapidly—sparrows, blackbirds and larks—are associated with agriculture. In recent decades, agriculture has grown to produce more food, but cleared landscapes have become unlivable for birds.
“We need to change the way we grow food. Birds are signaling that we are doing it wrong, "as the study says. The study offers the example of the 1990s effort to switch to no-till farming, which reduced greenhouse gases and soil erosion（侵蚀）. “Farmers are innovators. And they've done it before. This is a great opportunity to have a huge impact on birds."
1.What's the study mainly about？
A.The climate issues. B.The disappearing birds.
C.The agricultural problems. D.The environmental protection.
2.How is the second paragraph mainly developed？
A.By listing figures. B.By giving examples
C.By analyzing reasons. D.By making comparisons.
3.What's the main reason behind the birds' habitat loss？
A.Climate change. B.Greenhouse gases.
C.Industrial agriculture. D.Disrupted migration patterns.
4.What does the study suggest as a solution？
A.Producing more food. B.Clearing more landscapes.
C.Reducing the use of pesticide. D.Adopting new means of farming.

At least 115 Chinese miners have been pulled alive from a flooded coal mine after more than seven days trapped underground.
Rescuers cheered and some shed tears as the latest survivors emerged alive Monday after more than a week trapped in a flooded mine in north China's Shanxi Province. Officials were also relieved as their round-the-clock rescue mission prevented one of the country's worst mining disasters.
The head of the province's Work Safety ministry, Luo Lin, was among thousands of relatives waiting desperately for news at the pit entrance after rescuers said they had heard voices deep within the mine shaft over the weekend.
It is a miracle in China's mining rescue history, Luo says. He thanked the rescuers for their effort as he counted the miners leaving the entrance.
By late evening Monday, 115 miners had been pulled out alive, China's state media said. They were led to waiting ambulances with their eyes covered to prevent the glare from lights. All are said to be in a stable condition after being trapped in water for nearly nine days. They were able to breathe during their ordeal thanks to air pockets.
Three-thousand rescuers dug and pumped water for seven days to reach the miners at the Wangjialing Coal Mine, which is considered a modern facility.
The first survivors were brought to the surface shortly after midnight on Monday. Attempts to reach the 38 who remain trapped are continuing.
153 people were believed to be trapped underground. But families say this is an underestimate, claiming many more were working in the mine at the time of the flooding.
A preliminary investigation last week found that officials had ignored reports of water leaks prior to the accident.
China relies heavily on coal to fuel its booming economy. But it has some of the most dangerous mines in the world, with many mine bosses ignoring safety concerns to meet demand and chase profits.
The government has sought to improve safety in recent years by clamping down on illegal mines and this seems to have prevented many deaths.
According to official figures, 2,631 coal miners died in 1,616 mine accidents in China in 2009 – down 18 percent from the previous year.
1.Which is the best title of the passage?
A. The Flooded Coal Mine
B. Miners Trapped were Saved
C. The Worst Coal Mine Accident
D. 115 Miners Rescued, 38 Still Missing
2.The underlined word “round-the-clock” in Para 2 most probably means “_______”.
A. finishing before a particular time
B. changing the time shown by clock
C. all day and all night without stopping
D. from the beginning to the end
3.Which of the following is True according to the passage?
A. Coal plays a decisive role in China’s economy.
B. Mine accidents have been increasing in recent years.
C. 115 miners were working underground when the flooding happened.
D. About 3200 coal miners died in mine accidents in China in 2008.
4.At least 115 coal miners were rescued _______.
A. on the day the accident happened
B. after more than 7 days trapped underground
C. after working underground for 9 days
D. 10 days after the accident happened

高三英语单项填空简单题查看答案及解析
More than a billion people around the world have smart phones, almost all of which come with some kind of navigation app such as Apple Maps or Amap. This raises the age-old question we meet with any technology: What abilities is our brain losing to these apps? But also, importantly: What abilities are we gaining?
Talking with people who are good at finding their way around or good at using paper maps, I often hear a lot of annoyance with digital maps. North/south direction gets messed up, and you can see only a small section at a time. I can really understand that it may be quite disturbing for the already skilled to be limited to a small phone screen.
But consider what digital navigation aids have meant for someone like me. Although being a frequent traveler, I'm so terrible at finding my way that I still use Apple Maps almost every day in the small town where I have lived for many years.
In many developed nations, street names and house numbers can be meaningful, and instructions such as go north for three blocks and──then west’’ make sense to those familiar with these rules. In Istanbul, however, where I grew up, none of those hold true. For one thing, the locals seldom use street names. Besides, the city is full of winding and ancient alleys(小巷) that cross with newer avenues at many angles. In such places, you’d better turn to the locals. In the countryside, however, there is often nobody outside to ask. In fact, along came Apple Maps, like a fairy grandmother whispering directions in my ear. Since then, I travel with a lot more confidence, and my world has opened up.
Which brings me back to my original question: While we often lose some skills after depending on new technology, this new equipment may also allow us to gain new abilities. Maybe when technology closes a door, we should also look for the doors it opens.
1.Why do people who are skilled at reading paper maps feel upset?
A.They are interested in reading paper maps,
B.They don’t know how to use navigation, apps.
C.They are limited to a single smart phone app.
D.They are confused by digital maps’ direction.
2.According to the text, which is the best way to find the destination in Istanbul?
A.Asking local people the way.
B.Following the navigation app.
C.Getting familiar with the city rules.
D.Looking for street names and house numbers.
3.What’s the author’s attitude towards the navigation apps?
A.Cautious B.Ambiguous
C.Favorable D.Critical
4.What could be the best title of the passage?
A.Benefits of Navigation Apps
B.Disadvantages of Navigation Apps
C.My World Opens Up by New Technology
D.Have Navigation Apps Worsened Our Brain?

It has been more than twenty years since pioneering British computer programmer, Sir Tim Berners Lee, created the World Wide Web. But could he have ever imagined how much the web would change our lives? And would he approve of how some British students are taking advantage of his invention?
Universities and exam boards around the UK are becoming increasingly concerned with the rising number of cases of plagiarism, many of which are facilitated (助长) by the Internet access.
In the UK most school and university students complete coursework throughout the academic year which contributes toward their final mark. In many cases coursework makes up the main part of the qualification. Since coursework is completed in the students’ own time it cannot be monitored by teachers in the same way as an exam.
Derec Stockley, director of examinations in the UK, explains, “Plagiarism affects coursework more than anything else, and in the cases that come to our attention, more and more are linked to the Internet.”
At a university level recent reports suggest that plagiarism has evolved from separate cases of individual cheating to systematic and even commercial operation. Students can now pay for bespoke essays to be written for them by experts.
It is estimated that the market in online plagiarism is now worth 200 million pounds a year. Every month more and more websites offering to write student’s essays for them appear on the Internet.
Barclay Littlewood, owner of Degree Essays UK employs 3,500 specialist writers and charges between 120 pounds and 4,000 pounds per essay. However, Mr. Littlewood refutes the accusation that he is helping students to cheat.
1.What dose the underlined word “plagiarism” in Paragraph 2 mean in the passage?
A．coursework B．problems of the Internet

A 2 billion year old Martian (火星的rock appeals to have at our time been full of water from the surface of the Red Planet.
“Here we have a piece of Mars that I can hold in my hands. That’s really exciting,” Carl Agee, director of the Institute of Meteoritics at the University of New Mexico, told the Associated Press.
Agee led a team of scientists who published their report on the newly discovered meteorite （陨石），nicknamed Black Beauly, The rock is estimated to have contained 6,000 parts per million water? and scientists believe it likely interacted with water at a time when most of the planet’s surface was believed to have been arid.
The baseball-size rock was discovered in the Sahara, and scientists say it contains more evidence of water than any of the other known Martian rock samples.
“It’s fairly fresh. It hasn’t been subjected to a whole lot of weathering (风化作用），” University of Alberta meteorite expert Chris Herd told the AP.
Billions of years ago an eruption on the surface of Mars, likely caused by a volcano or planet collision, sent the rock into space, where it eventually made the journey to Earth, Agee and his team said the sample is “strikingly similar to the volcanic rocks examined by the NASA rovers Spirit and Opportunity on the Martian surface.”
Over the years, scientists have collected more than 60 Martian rock samples, with most being discovered in the Sahara and Antarctica. The new sample is much older than most of the other specimens, which are about 600 million years old or younger. The oldest known sample is an estimated 4.5 billion years old.
1.The underlined word “it”in Paragraph 3 refers to “ ”.
A. Mara B. the Red Planet
C. Black Beauty D. the report
2.Where was the meteorite found?
A. In the Sahara. B. In Antarctica.
C. In Mars. D. In America.
3.Which of the following is NOT true according to the passage?
A. Black Beauty has the size of a baseball.
B. Blank Beauty contains the most evidence of water among the known Martian rock samples.
C. An eruption on the surface of Mars sent the rock into Earth directly.
D. Black Beauty is not the oldest known sample.
4.Where can we most probably read this text?
A. In a personal diary. B. In a science report.
C. In a travel magazine. D. In a geography textbook.
