Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.
“Our findings suggest that there is something about actively falling snow that causes wolves to slow down,” said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. “We don’t know the exact mechanism behind that. It’s unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation（降雪量）might affect wolves’ hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey.”
Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry（测距仪） data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.
With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.
“Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources,” said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.
“Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios（设想）but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes.”

A. identify B. overlook
C. overcome D. disturb
2.Increased precipitation might have the following effects on animals except _______.
A. poor health B. nutritional shortage

When you watch a movie in the cinema, you may wonder how “the moving pictures” is made and where the voices, and noises and music come from. Now here is the answer.
In modern times, the middle part of a cinema film has lots of small photographs, each one of which is different from the one before it. Each photograph is brought in front of a strong light, and there it stops for a very small part of a second. This photograph, therefore, appears on the screen, and we see it. Then the light is covered and the next photograph is moved to the position in the front of the strong light. Meanwhile, the metal cover turns away from the light. Thus, the second photograph is shown on the screen. This is done again and again, twenty-four times a second, and we think we are watching a moving picture on the screen. But nothing on the screen actually moves. ”The moving picture” is in fact made up of a lot of bits. We see about 86,000 different pictures every hour, but none of them moves.
The voices, noises and music are recorded on the side of the cinema film. The record looks like marks of strange shapes. The side of the film passes in front of another light, and the rays of light which pass through change as the marks change. These marks have been made from the voices and other sounds of the people and events in front of the cinema when the film is being made. The marks may be considered as “printed sounds”.
1. When a cinema film is shown, how long does each photograph appear on the screen?
A. One twenty-third of a second.
B. One twenty-fourth of a second
C. A few seconds
D. One thirty-fifth of a second.
2. Why can we see pictures moving on the screen?
A. We see about 86,000 different pictures every hour.
B. Each picture is a little different from the former.
C. Photographs change quickly.
D. Both B and C.
3. What is a cinema film made up of?
A. Small photographs and a strong light.
B. Small photographs and the sounds.
C. A lot of bits.
D. Voices and photographs.
4. Which is the true about the sound record?
A. It sounds strange.
B. It looks as irregular marks.
C. It is printed in the middle of a film.
D. It is made while the film is being shown on the screen.
