Most dog owners have probably been puzzled waiting for their dog to do its business. Instead of just finding a soft area of grass to go number two, they make a whole ritual(仪式) out of it, spinning in a circle before finally squatting(蹲下). Luckily, the ultimate pet owners’ question may finally have been answered.
A few theories have circulated about why dogs might circle before pooping and most are similar to the reasons they spin before lying down. Trampling around in a circle would flatten the grass around, which would keep tall blades(叶片) from trapping their waste. Another explanation could be that they’re scanning for snakes and predators before they become completely occupied.
But Czech researcher Hynek Burda didn’t quite buy into those theories. Dogs evolved from wolves, which didn’t need to worry much about tall grass. And if they were scanning their environment, keeping still to listen and sniff would be more effective than giving the area a quick once-over. Instead, Burda suggested that dogs
spin to get a feel for the Earth’s magnetic pull.
The Earth has a magnetic field around it protecting it from radiation from space, and some animals seem to use it to get a sense of where its North and South poles are. For instance, it’s how birds know which way to migrate. In 2013, Burda published a study in the journal Frontiers in Zoology suggesting dogs have a strong internal compass, too. He and his team spent two years watching 70 dogs poop and pee and recording which way they faced and how strong the magnetic(磁的) field was.
As it turns out, when the magnetic field was calm, dogs preferred to poop facing either north or south.
The pattern couldn’t explain why dogs like facing the Earth’s poles, but the researchers think it might help them remember where they marked their territory.
If they can remember which way they were facing, they might find it easier to find that spot again. So before you roll your eyes when your dog takes ages to do his business, remember that Fido might just be getting scientific about his potty spot.
27. What is the ritual for dogs when they do their business? A. They poop twice daily. B. They circle before pooping.
C. They usually make their owner impatient. D. They just find a soft area to poop. 28. According to Burda, dogs ________.

C. sniff around to scan the environment D. circle to face a certain direction
29. The writer cites “birds” in order to show ________. A. how magic they are B. dogs also can migrate C. dogs have inner compass
D. the differences between birds and dogs
30. It might be concluded that dogs ________.
A. have good reasons to take ages to do his business B. are more scientific than human beings C. are sensitive to radiation from space D. often play tricks with their owners 第二节(共5小题:每小题2分,满分10分)

___31___ While these compulsive(无法控制的) actions may appear to be irrational or pointless, and may even result in negative consequences, the individual experiencing the compulsion feels unable to stop him or herself.
The compulsive behavior can be a physical act, like hand washing, or a mental activity, like counting objects. When an otherwise harmless behavior becomes so consuming that it negatively impacts oneself or others, it may be a symptom of obsessive-compulsive disorder (OCD)(强迫症).
___32___The former is an overwhelming desire to do something, while an addiction is a physical or chemical dependence on a substance or behavior. People with addictions will continue their addictive behavior, even when they understand that doing so is harmful to themselves and others. ___33___
Unlike compulsions and addictions, which are acted out uncontrollably, habits are actions that are repeated regularly and automatically.
Habits typically develop over time through a natural process called
“habituation,” during which repetitive actions that must be consciously initiated eventually become subconscious and are carried out habitually.
While there are good habits and bad, unhealthy habits, any habit can become a compulsion or even an addiction. ___34___ For example, the good habit of exercising regularly can become an unhealthy compulsion or addiction when done to excess.
Common habits often develop into addictions when they result in a chemical dependency, as in the cases of smoking. The habit of having a glass of beer with dinner, for example, becomes an addiction when the desire to drink turns into a physical or
emotional need to drink.
___35___While we can choose to add good, healthy habits to our routines, we can also choose to break old harmful habits. A. A compulsion is different from an addiction.
B. It currently affects about 1 in 40 adults and 1 in 100 children in the U.S. C. Some of these behaviors are visible actions while others are mental behaviors. D. In other words, you really can have “too much of a good thing.”
E. Compulsive behaviors are actions that a person feels “compelled” or driven to do over and over again.
F. Alcoholism, smoking, and gambling are perhaps the most common examples of addictions.
G. Of course, the key difference between a compulsive behavior and a habit is the ability to choose to do them or not. 第三部分 语言运用(共两节,满分45分)
