snowmobiles to prepare their summer hunting camps have found themselves cut off from home by a sea
of mud. There are also reports of sea ice breaking up earlier than usual, carrying seals beyond the reach
of hunters. Climate change may still be a rather abstract idea to most of us, but in the Arctic it is already
having great effects-if summertime ice continues to shrink at its present rate, the Arctic Ocean could soon
become almost ice-free m summer. The knock-on effects are likely to include more warming, cloudier
skies, and higher sea levels. Scientists are increasingly eager to find out what's going on in the Arctic.
For the Inuit the problem is urgent. They live in unsteady balance with one of the toughest environments
on earth. Climate change, whatever its causes, is a direct danger to their way of life. Nobody knows the
Arctic as well as the locals, which is why they are not content simply to stand back and let outsider experts
tell them what's happening. In Canada, where the Inuit people are trying hard to guard their hard-won
autonomy in the country's newest land, Nunavut, they believe their best hope of survival in this changing
environment lies in combining their ancestral knowledge with the best of modern science. This is challenge
in itself.
The Canadian Arctic is a vast, treeless polar desert that's covered with snow for most of the year.
Adventure into this area and you get some idea of the hardships facing anyone who calls-this home. Farming
is out of the question and nature offers few pickings. Humans first settled in the Arctic a mere 4,500 years
ago, surviving by taking advantage of sea fish. The environment tested them to the limits: sometimes the
settlers were successful, sometimes they failed and disappeared. But around a thousand years ago, one group
appeared that was uniquely well adapted to deal with the Arctic environment. These Thule people moved in
from Alaska, bringing dogs, iron tools and the like. They are the ancestors of today's Inuit people.
B. Ice-free summer around the Arctic.
C. Higher sea levels.
D. More cloudy skies.
B. to use their ancestral knowledge
C. to make the best of modern science
D. to use their ancestral knowledge and modern science
B. it's hard to farm in the Arctic due to the climate change
C. the ancestors of Inuit people stood out among the settlers
D. the Thule people from Alaska invented iron tools
B. Climate change around the Arctic
C. Global warming around the world
D. The Inuit and their ancestors around the world

查看习题详情和答案>>When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal(揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live, simply because it’s easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect(嫌疑犯) who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal’s home base by combining these patterns with a city’s layout(布局) and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets — that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example, that the younger the criminal, the closer to home the crime.
Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.
The program is just one way to use math to fight crime. O’Leary says that criminology — the study of crime and criminals — contains a lot of good math problems. “I feel like I’m in a gold mine and I’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”
1.
To find criminals, police usually ______.
A. focus on where crimes take place B. seek help from local people
C. depend on new mathematical tools D. check who are on the crime scene
2.
O’Leary is writing a computer program that ______.
A. uses math to increase the speed of calculation
B. tells the identity of a criminal in a certain area
C. shows changes in criminals’ patterns
D. provides the crime records of a given city
3.
By “I’m the only one who knows what gold looks like”, O’Leary means that he ______.
A. is better at finding gold than others
B. is the only one who uses math to make money
C. knows more criminals than other mathematicians
D. knows best how to use math to help solve crimes
4.
What is the main idea of the text?
A. Criminals live near where crimes occur.
B. Math could help police find criminals.
C. Crime records could be used to fight crime.
D. Computer software works in preventing crimes.
