小学生10分钟应用题系列答案The search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾伦望远镜阵列) in Hat Creek, California. The telescopes were partly made possible by a gift of twenty-five million dollars from Paul Allen. The total cost of the project is already fifty million dollars.
At present, there are 42 radio telescopes working at the Hat Creek observatory. The signals they receive are combined to create what is equal to a single, very large telescope. The telescope will be used to observe objects like exploding stars, black holes and other objects that are predicted but have not yet been observed. Seth Shostak of the SETI Institute says this is the first telescope whose main purpose is to search for signals from intelligent life in space. The SETI Institute is based in Mountain View, California. The organization supports the search for other life forms in the universe.
What makes the Allen Telescope Array unusual is that it can collect and study information from a wide area of the sky. In addition, the 42 telescopes can study information about several projects at the same time. That means studies of large areas of the sky can be made faster than ever before.
Some officials think the Allen Telescope Array will be completed in three more years. 350 individual radio telescopes are planned. The new abilities of the Allen Telescope Array will make searching for stars similar to the sun much faster.
An earlier search by SETI, Project Phoenix, studied about 800 stars to a distance of 240 light years. The project ended in 2004. With the Allen Telescope Array, astronomers hope to gather thousands of times more information in the search for life beyond our planet.

“Mum, what does it mean when someone tells you that they have a skeleton（骨骼）in the closet（衣橱）?” Jessica asked. “A skeleton in the closet?” her mother paused thoughtfully. “Well, it’s something that you would rather not have anyone else know about. For example, if in the past, someone in Dad’s family had been arrested for stealing a horse, it would be ‘a skeleton in his family’s closet’. He really wouldn’t want any neighbor to know about it.”
“Why pick on my family?” Jessica’s father said with anger. “Your family history isn’t so good, you know. Wasn’t your great-great-grandfather a prisoner who was transported to Australia for his crimes?” “Yes, but people these days say that you are not a real Australian unless your ancestors arrived as prisoners.” “Gosh, sorry I asked. I think I understand now,” Jessica cut in before things grew worse.
After dinner, the house was very quiet. Jessica’s parents were still quite angry with each other. Her mother was ironing clothes and every now and then she glared at her husband, who hid behind his newspaper pretending to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica’s closet. Just as she opened the door and reached in to hang a skirt, a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor. Jessica’s mother sank in a faint（晕倒）, waking only when Jessica put a cold, wet cloth on her forehead. She looked up to see the worried faces of her husband and daughter.
“What happened? Where am I?” she asked. “You just destroyed the school’s skeleton, Mum,” explained Jessica. “I brought it home to help me with my health project. I meant to tell you, but it seemed that as soon as I mentioned skeletons and closets, it caused a problem between you and Dad.” Jessica looked in amazement as her parents began to laugh madly. “They’re both crazy,” she thought.
【小题1】According to Jessica’s mother, “a skeleton in the close” means ______.
| A．a family honor | B．a family story | C．a family secret | D．a family treasure |

| D．they both thought they had won the quarrel |
A survey by an international temporary service agency found that U. S. managers believe that people with a sense of humour do better at their jobs, compared with those who have little or no sense of humour. In fact, about 96 percent of those surveyed said people with a sense of humour do better.
The survey went on to point out that the results suggest that a sense of humour may help light-hearted employees keep their jobs during tough times. And, what's more, it may push them up the corporate ladder past their humourless colleagues. Why? It seems that those with a sense of humour are better communicators and better team players.
Studies have shown that happy workers are more productive. In fact, a researcher at California State University found that humour could help the employees to release tension.
Research done by psychologist Dr. Ashton Trice at Mary Baldwin College in Virginia showed that humour helps us think. When people feel stuck on important projects, they tend to feel angry or depressed. According to Dr. Trice's research, taking time out to laugh can help us to get rid of negative feelings and allow us to return to a task or move on to another project unaffected by past defeat.
If humour is really this important, then why don't we use it more often on the job? Most likely, the main reason is that many people are unaware of the positive effects of humour in the workplace. However, it is important to realize that some humour is not suitable for the workplace, and that it is often used at wrong times.

| A．they like keeping silent when working |
| B．they don't know the positive effects of humour |
| C．they think they should obey the rules |
| D．they don't like joking or laughing |
| A．to feel surprised |
| B．to get along with |
| C．to be worried |
| D．to be successful |
