Ms. Stilwell, CEO of Victoria Stilwell Positively Dog Training, offers some advice on how to read dog behavior to avoid an attack on a person or the other dog.People are usually attacked by a dog they know, “It happens when the relative has brought his dog over, or it happens at a friend’s house，” says Ms. Stilwell, “We just let our guard downhere.”“Obvious signs include barking, growling, if the dog’s ears are flat or suddenly prick up. Some dogs salivate (流口水) when they are stressed, others cower (畏缩), ”says Ms.Stilwell.“Dogs will wag (摇) their tails when they are upset or over-aroused.” Similarly, if an unfamiliar dog rolls on its back to expose its belly (腹部), it doesn’t necessarily want to be petted. It might be asking you to move away.A dog that attacks is often acting out of fear, says Ms. Stilwell. Those signs of fear may include a dog yawning, turning its head away when someone approaches, tensing up or staring. Some dogs will slightly lift what Ms. Stilwell calls“the anticipatory paw (先行爪)”，because it shows that they think something negative is about to happe n. Another subtle warning sign is when a dog slightly lifts its lip to show teeth. Also, when a dog’s flat tongue is relaxed or curved at the sides, it means there is tensio n.“If a dog is on a child and you’re pulling it off, you’re making the wound on the child deeper, ” Ms. Stilwell says. Instead, “take a coat or T-shirt and put it over the dog’s head, ”she says. When dogs can’t see, they panic and open their mouths.【解题导语】本文是一篇说明文，主要介绍了如何读懂狗的行为，防止被狗咬伤。

B(2016·石家庄二模)Pilates, yoga and the running machine get all the attention when it comes to popular ways to stay healthy. There is, however, a more humble exercise that might not be so attractive, but has all the benefits—walking.Certified fitness professional Jolynn Jaekel explains, “What I love about walking is that anyone can do it at any age and any fitness level. Plus, it is good for your heart, your head and your wallet.”A recent report details the health benefits of walking. The report found that walking regularly to fulfill the 150 minutes of moderate physical exercise every week, recommended by the UK’s chief medical officer, could save 37, 000 lives each year. Scientists at the Lawrence Berkeley National Laboratory in California found that quick walking reduces the risk of heart disease more effectively than running. They observed participants aged between 18 and 80 over a six-year period and found that walking reduced the risk of heart disease by 9.3%, while running reduced it by 4.5%. And there is even more good news: 30 minutes of quick walking over five days could help you sleep easily, according to research by Oregon State University. The study by the university showed that walking helped participants sleep better and feel more alert during the day.The sooner you get started, the sooner you’ll notice the differences in your mind and body.So, go out for your 30-minute walk in a nearby park or green space.【解题导语】本文是一篇说明文，主要介绍了健康生活方式中的最简单有效的方式——步行。
