APhiladelphia (CNN) — Hazel Donnelly was taking her husband to the doctor when they got a call that their building was on fire.Her first thought was about Kramer. “I don’t have child ren of my own, so my cat is like my child. I became very sad,” said Donnelly, 50. “What if he didn’t make it?”Once she arrived home, Donnelly asked firefighters (消防员) to get her cat, but they were busy trying to control the fire. Then Red Paw Emergency Relief Team arrived. The organization helps pets and their owners for free when disaster strikes. Jen Leary, who set up the group, helped find the animals once the fire was out.“Everyone who received their pets started to cry,” said Donnelly.No one was hur t, but the Donnellys’ building was badly damaged, and they weren’t sure where they were going to stay. Donnelly was excited to learn that Red Paw could provide free short-term care for Kramer, her 17-year-old cat.“When someone loses everything in a fire, they shouldn’t then be forced to lose their pets — their family members —as well,” Leary said. “Letting them know,‘We’ll take care of your animal like it is our own’ means the world to people.”After a big fire in 2011, Leary formed her organization. Since then, Leary and her group have provided help to nearly 1,000 animals and their families throughout southeastern Pennsylvania. Like the Red Cross, but for animals.Red Paw cared for the Donnellys’ cat for more than three weeks. “I cried when we were reu nited,” said Donnelly. “They went above and beyond the call of duty. I am so thankful.”For Leary, helping families and their pets is what her work is all about. “My hope is that it’s a start, and they can move forward together,” she said. “After going thr ough such a sad thing, it’s so good to have a happy ending.”21.

Who looked after Kramer for a long time after the fire?A. A doctor.B. Jen Leary.C. Red Paw.D. The Red CrossBWelcome to Death Valley. The very name of this national park in eastern California might fill some people with dread, but you’re not afraid. You’re just out enjoying the desert sunshine. Besides, there’s nothing out here but some rocks.Some of the rocks in Death Valley weigh hundreds of pounds. And in the ground behind each rock is a mysterious trail (痕迹), as if the rock had been pushed along in the dirt.So who is moving the rocks? Nobody. It was nearly 100 years ago when these unusual “sailing stones” were first reported. People have been trying to find out the stones’ secret ever since. One early ex planation was that winds were moving the stones. Other explanations have included animals, and, of course, aliens (外星人).Until the 1990s, one widely held theory was that the rocks were stuck in sheets (片) of ice that were being blown across the desert. (Death Valley does get cold enough for ice to form on some winter nights.) However, research later showed that to move such large ice sheets, the wind would have to blow at hundreds of miles per hour. There are strong winds in Death Valley — but not that strong.Then, in 2006, a scientist named Ralph Lorenz came up with a new theory. He suggested that in the winter, thick ice forms around the rocks. When the ground begins to thaw (解冻), the rocks, wearing ice, sail along, leaving trails behind them. Lorenz put his theory to the test in his own kitchen. He dropped a rock into a dish, added a little water, and stuck the dish in his fridge. Later, he took out the rock and placed it in a dish of water with sand at the bottom. Sure enough, with just a breath, Lorenz was able to send the rock moving across the water — leaving a trail in the sand as it moved.Has Lorenz solved the mystery of the sailing stones at last? Perhaps. On the other hand, neither Lorenz nor anyone else has ever actually seen the stones move. Maybe aliens are responsible after all.25. The underlined word “dread” in Paragraph 1 probably means “_____”.A. fearB. angerC. surpriseD. excitement26. According to the theory in the late 20th century, the rocks were probably moved by _____.A. the iceB. the windC. aliensD. animals27. What did Ralph Lorenz find?A. The wind in Death Valley could reach a speed of 100 mph.B. The rocks in Death Valley couldn’t move by themselves.C. Death Valley could get cold enough for ice to form.D. Water helped the rocks in Death Valley move.CDear friends and colleagues (同事) of Tom Blumenthal,We are organizing a celebration honoring Tom’s research career (生涯).
