2 . While some say school safety depends on guns, cameras or alarms in classrooms, Mark Gomer and Kristi Schiller think specially trained dogs should play an important role in preventing violence in schools.
Gomer’s for-profit company has sent a gun-and-drug detecting dog to patrol (巡查) the halls of an Ohio high school, while Schiller is launching a nonprofit program in Houston to give schools the trained dogs for free.
Gomer’s first full-time safety dog is a three-year-old Dutch shepherd named Atticus, who is reported to duty this school year at Oak Hills High School in Green Township in southwest Ohio. The dog was trained at the school before the summer break, said Gomer, co-owner of American Success Dog Training in Bridgetown, Ohio. Atticus has won over students, parents, teachers and district Superintendent Todd Yohey, who initially worried what people would think of him spending $10,000 on a dog. Gomer has talked to a lot of parents and faculty, and they are saying it was money well-spent, he said.
For her part Schiller is looking to provide safety dogs to schools free of charge. She hopes her new initiative, program “K9S4KIDS”, does for schools what her program “K9S4COPS” did for police departments. She has placed more than 60 dogs with agencies in three years. “These dogs are extremely social, yet highly qualified warriors that are accustomed to going straight to the source of a threat or shooter and disengaging the suspect armed with the weapon,” said Schiller.
As the programs get up and running, questions remain about possible health problems and distractions the dogs can cause.
A school safety expert said those are concerns parents and schools will have to work out. Ken Trump, president of the Cleveland-based National School Safety and Security Services consulting firm, discussed the issue in general because he was not familiar with either program.
He said the dogs would have to be extremely social to deal with students’ initial excitement “Kids are going to like those dogs,” Trump said, “There are concerns to work around, but with the right dogs and right handler and the right policies and procedures, they should be very beneficial. The dog might be a distraction in the beginning, but they will become part of what students expect to see when they go to school.” “There is so much these dogs can do,” said Ted Dahlin, a deputy who serves on the K9S4COPS board of directors. “If I were going to pick a school to make trouble, it would be one that I knew didn’t have a dog.”

8 . The population of rare Atlantic puffins in Maine, US, took a hit this year, as the number of chicks to survive a tough summer collapsed. The state’s coastal bays and the Gulf of Maine are among the fastest warming large water bodies on the planet, making the puffins’ fate a test-case for how climate change could disrupt marine ecosystems worldwide.
The phrase “took a hit” (in the 1st paragraph) probably mean “________”.
| A．suffer heavy losses | B．escape bad fortune |
| C．increase on a large-scale | D．decline moderately |
9 . Climate change is caused by the extremely high levels of dangerous chemicals in the atmosphere, particularly carbon dioxide. We all know the effects could be disastrous, but are we aware of the possible solutions?
Solution one:
Though it sounds crazy, a group of researchers from British universities is making a plan to build a 12-mile pipe, held up by a huge balloon, which would let a lot of chemicals, such as sulphur dioxide (SO2), go into the atmosphere. Surprisingly, there is good science behind the idea. The chemicals would form a protective layer around the earth that would reflect sunlight and so cool the earth, much like the effects of a volcanic eruption.
Cost: around $10 billion a year
Benefits: This plan would produce almost instant results.
Risks: Volcanoes have almost destroy human in the past through the chemicals released in the atmosphere, and the same thing could happen again with this plan.
Solution two: stir up (搅动) the oceans
Intellectual Ventures, which is a company, has planned to build a million plastic tubes, each about 100 meters long, and use them to stir up the ocean. Why, you might be wondering, would we want to do this? Again, the answer is scientifically effective. The bottom of the ocean is almost freezing and by stirring it up, cold water would come to the surface and absorb (吸收) heat and CO2, and so cool the planet.
Cost: tens of millions of dollars
Benefits: This plan is relatively cheap and technically possible new.
Risks: The tubes would possibly destroy sea life, and the plan may not work.
Solution three: stop burning fossil fuels
This is undoubtedly the best solution but is it really likely to happen in the near future?
Cost: unknown
Benefits: It’s a simple and effective plan.
Risks: It may already be too late. Without real action, this plan could just mean “do nothing”.
