Stacey Hillman, who is 10 years old, was reading a magazine about police dogs needing bulletproof vests . She thought that someone should start raising money for the police dogs. After she got permission from Chief LaBrusciano, she went to the County Sheriff Don Eslinger. She got busy visiting all the police dogs and telling the departments about her new charity. She made "collection boxes" by using bottles and put a picture of her with a police dog on it. She put these bottles in vet's offices and pet stores. The Chief from her hometown police department helped make Stacey's idea an official charity -- Pennies to Protect Police Dogs. The more money she collected, the more popular she became, and the more people offered to donate and help her with her goal of giving every police dog effective protection. Stacey travels all around her state to raise money and tell people how important the police dogs are. She speaks at schools, and they donate to her charity, too. Since Stacey started her charity, she has bought bulletproof vests for the police dogs with all the 140 thousand dollars she has raised. But she has many more K-9 friends that still need to be protected and she promises to keep doing her charity until every police dog in the whole country has a bulletproof vest. Each vest costs $700, and every police dog should have one. There are not always tax dollars to provide K-9s with these vests, and very few departments have them. The police dogs save lives just like police officers do, and often the police dogs are the first to go in. Stacey depends on donations from everyone to provide the dogs with bulletproof vests. "K-9 friends" probably refers to _ . A) police officers B) local people C) police dogs D) friends at school

Greenwich is on the River, five miles from the middle of London, and its history is two thousand years old. The first English people were fishermen there, and they named the place Greenwich, meaning "green village". Later the English kings and queens lived at Greenwich in their beautiful places. The name of the earliest palace was Placentia. Henry VIII lived there. He knew that England must be strong at sea. So he started two big ship-yards at Greenwich. But trouble was coming to Greenwich. In 1649, a war started in England and for eleven years there was no king. The men who had worked for him at Placentia decided to live the place themselves. They sold all its beautiful things. Finally, the war ended and King Charles II came back. But Placentia was falling down. So King Charles built a new and bigger palace, which is now open to the public. At this time, Charles was worried about losing so many of its ships at sea: their sailors did not know how to tell exactly where they were. So in 1675, Charles made John Flamsteed, the first astronomer in England, try to find the answer. Flamsteed worked in a new building on the high ground in Greenwich Park. From it with a telescope which he made himself, Flamsteed could look all round the sky. And he did, night after night, for twenty years. Carrying on Flamsteed's work a hundred years later, an astronomer called Harrison finally made a clock which told the time at sea, and helped sailors to know where they were. You can see Harrison's clock, still working, in Greenwich's museum of the sea. Because of Flamsteed's work, every country in the world now tells its time by Greenwich Time. Charles made John Flamsteed try to find _ . A) how to build strong ships B) how to tell sailors' positions at sea C) how to tell the exact time D) a place to set up a telescope

Q: Around the world coral reefs are facing threats brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive in the long run. Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record. During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death. The coral's ability to adjust to cool temperatures surprised the researchers, who say the study's results show the complexities of monitoring coral health in response to different environmental factors . "Global warming is associated with increases but also decreases of temperatures," said Deheyn, one of the researchers. "Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change." According to the research, _ . A) corals may continue to grow in cold events after a few days B) cold events help corals grow more quickly in a short time C) corals show no response to hot temperatures in the first days D) corals are whitened mainly because of warm temperatures

It's easy to see how to help some people, but what about those whose needs are not so clear? This story may have happened not long ago--- but it was a lesson which has stayed with me and helped me ever since. It was Thanksgiving and I was volunteering with my parents at a shelter for the needy. We served hot food to whoever came in. Most of our dinners looked like they had been having hard times; their clothes were worn out and dirty. Then, a man came in, who looked anything but needy. He was well dressed. I wondered what he was doing there and my jaw dropped in amazement when he joined the line for food. The closer he came to my service station , the more I muttered . What was this man doing? Surely he wasn't going to take food which was meant for those who were really in need! Then my mother quietly took me to one side. She said, "You have thought that the needs of the people who come here must be purely physical, hunger, etc. And this gentleman doesn't seem to have any of those problems. But what if his needs are emotional ? What if he needs comfort, friends, or just to be among other human beings? Her words hit me like a ton of bricks! I felt like I should apologize to the man--- but I didn't. About a week later the shelter received a large donation from an source. I can't help but wonder if it came from that man. Now, whenever I meet someone I remember my mother's lesson and try to send kindness their way, no matter how they look. Needs aren't always seen. But kindness always makes a difference. How did the author feel as the well-dressed man joined the line for food? A) Surprised B) Excited C) Nervous D) Hopeless
