Question: It is easy for us to tell who our family members are, but do plants recognize their own family? Some do, scientists say, according to a report by Science News in early 2010. Guillermo P. Murphy and Susan Dudley are two plant scientists from McMaster University in Hamilton, Canada. They did a few experiments with Jewelweeds, a kind of flower that grows in wet, shady spots. They found that the flowers seem to know their own flower family. In their experiments, Murphy and Dudley planted jewelweeds in pots with either _ or strangers. When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food. Jewelweeds usually grow in the shade, where sunlight is not enough. When jewelweed seedlings were planted with siblings, they grew a few more branches than they usually would if they were alone - but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete. According to the Science News report, Jewelweeds are not the first plants that plant scientists have studied for family recognition. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach - where it may be hard to get fresh water. In that experiment, the scientists found that when sea rockets were planted with siblings, they tolerated each other. But when they were planted with strangers, the sea rockets reacted by working extra hard to grow lots of roots. Dudley says this just because sea rockets, on the beach, get plenty of sun but struggle for water - so when they're threatened, they compete for water. Jewelweeds have plenty of water but have to compete for sunshine, so they grow more leaves. 1. Who are Guillermo P. Murphy and Susan Dudley?

Question: Many people like animals and raise one or more as pets--dogs, cat or some kinds of birds. I love dogs, too. My aunt gave me a dog on my birthday. We call it Wangwang. It is a little black dog. He is friendly and helpful. Most of the time he likes to run and play with me. Sometimes he follows my father around in the fields. One day, my father took off his grey coat and put it on the ground under a big tree. Wangwang stood watching him. My father said, "Watch over my coat, Wangwant." Wangwant sat down beside the coat. My father went on working. After he finished his work, he forgot all about his coat and went home. Late in the evening I didn't see my dog. I looked everywhere for him calling, "Wangwang, Wangwang!" But Wangwang didn't come back. Soon my father wanted something that was in his coat pocket. Then he remembered what he had done. He went back to the big tree. What do you think he saw? Wangwang was sitting on the coat so that nobody could take it away. 1. Do people like animals?

Question: When this story happened, they were working around a very large house. Their job was to do the cleaning. It was not a difficult job, but sometimes it was a little dangerous, because they had to walk below where workmen were working. Often these workmen dropped something from the top of the house many meters high to the ground. One morning Joe was working near the house with a cigarette behind one of his ears. Suddenly somebody on the top shouted, "Look out!" But Joe did not "look out". He looked up. And as he did so, a long knife missed Joe's head, but it cut off one of his ears. At once he put his hand to one side of his head and cried out, "I've lost an ear. Help! Help!" Jeff ran up to help his friend. "Look for my ear," Joe told him. "It must be on the ground somewhere." Jeff looked everywhere for the missing ear. At last he found an ear on the ground. He picked it up and carried it to Joe. "Here you are," he said, "I've found it." Joe looked at it. "No, that's not my ear." he said, "Mine had a cigarette behind it." 1. What were they doing?
