dogs. All the animals had to do was pull the lid off a food container, containing a sausage treat. Monique Udell studies animal behavior at Oregon State University in Corvallis. She tested 10 pet dogs and another 10 dogs from an animal shelter. In one set of tests, a person was nearby but did not encourage or discourage the dogs. Those dogs typically spent 10 to 15 percent of their time gazing at the person. They spent a mere 5 percent of their time or less touching the container. Udell offered the same challenge to wolves. These animals had been raised and fed by people but still lived outdoors. Here, the wolves didn‟t look at the nearby person. Instead, they devoted about 90 percent of the time to struggling with the box holding a treat. When someone walked around the dogs and actively encouraged them to keep trying to open the box, the dogs did spend more time handling the problem. A few more even managed to open the box. But their success rate still did not match the wolves. The dogs and wolves were also tested when no one was present. But even then, the dogs didn‟t paw or teat the box much more than they did when a human was present. 29. According to paragraph 2, how did the dogs perform in the experiment? A. They showed reduced intelligence B. They found the treat in the box less attractive C. They found the wolves were dangerous D. They spent more time waiting for help 30. What was the effect of encouragement on the dogs? made their success rate improve a lot made them seek less guidance made them a little more devoted to the task made them able to pete with the wolves is the main idea of the text? A. How wolves and dogs differ from each other B. The reason why wolves are dangerous C. Dogs are more relaxed when no one is around D. Wolves beat dogs in problemsolving tests D Noise pollution in cities is causing out health to suffer, according to the World Health Organization. Recently, researchers at the Free University of Brussels in Beigium have developed an applocation: NoiseTube. It allows everyone who downloads it the ability to measure the amount of noise they are exposed to by transforming their smart phone into a sound level meter. NoiseTube works by recording sound levels and GPS locations. Once launched the app shows decibel(分贝 ) levels of green or red depending on the level of noise. That information is then sent to the NoiseTube server via the Inter where a noise map is produced and then made available to the user. Since its launch, the app has been popular with munity groups who want to monitor their own noise levels. According to D‟hondt of the Noise Tube project, these groups don‟t think that city produced noise maps give an adequate interpretation of the level of noise they‟re experiencing. City produced noise maps are based on statistical models involving very few actual measurements. NoiseTube on the other hand gives a detailed account of the level of noise experienced at a specific time and location. Ten people walking the same area from 9 to 10 am every day for one week can make a valid(有效的 ) and detailed map for an area of a couple of blocks, D‟Hondt said. “It‟s reasonable effort by the munity groups to produce these maps, and with it they can go to the authorities and have real evidence about what they‟re experiencing.” So far these sorts of noise maps have been produced for a number of European cities. The app has been downloaded by 10,000 people with 2,700 people registered on the NoiseTube website. 32. How does NoiseTube produce a “noise map?” A. The NoiseTube server analyzes noise information vis the Inter. B. The NoiseTube server analyzes noise information via GPS devices. C. Decibel levels of noise are transformed by a unique device. D. It produces a “noise map”automatically when it collects enough information. reliability of city produced noise maps is questionable because __________. A. the research is based on only a few actual measurements B. they can only be used at a specific time and location C. their operating principles are not clear D. the collected information isn‟t enough to prove it 34. Why are munity groups producing noise maps? A. To make more people use noise maps B. To prove they are useful tools to control noise pollution C. To make the authorities aware they are experiecing noise pollution D. To collect valid information for the researchers 35. This passage is mo。
