SCIENCE NEWS FOR KIDS

  Welcome to log on a new Web site-SCIENCE NEWS FOR KIDS!

  Our goal is to offer timely items of interest to kids, accompanied by suggestions for hands-on activities, books, articles, Web resources, and other useful materials.

  Our emphasis is on making the Web site appealing by offering kids opportunities to comment on and grade the subject matter, get ideas for science projects, and try out mathematical puzzles.At the same time, we offer teachers creative ways of using science news in their classrooms.

  The Science News for Kids Web site, funded by grants from several corporations and foundations, enhances the usefulness of Science News in the middle-school classroom and offers recreational reading and activities for students interested in science.

  A section of the Science News for Kids Web site is devoted to particular interests.At present, we have six such zones:a weekly brainteaser for those who enjoy solving and inventing puzzles(PuzzleZone), entertaining science-fiction composition exercises for those interested in writing(SciFiZone), and weekly science fair profiles along with science project ideas and tips(ScienceFairZone).The GameZone contains a small selection of logic and memory games, implemented as Java applets(小应用程序).The TeacherZone has materials, including question sheets related to the feature article of the week, so that teachers can bring science news topics to the classroom.The LabZone features a weekly hands-on activity or science project idea.In the future, we might add additional zones, for example, for kids interested in robotics, the environment, computers, mathematics, or veterinary medicine and animals.

第三部分:阅读理解(共20小题;每小题2分,满分 40分)
阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。
A
A university math tutor has discovered the science behind “singledom”, finding that our chances of finding the perfect partner are just 1 in 285,000. Peter Backus, a tutor at the University of Warwick, published his “Why I Don’t Have a Girlfriend” paper after a three-year love drought.
His unconventional study uses a famous math formula called The Drake Equation(德雷克等式), which was first used to estimate the existence of extra-terrestrial(地球以外) life.
The results don't look promising for British singles. 30-year-old Mr. Backus found that out of the 30 million women in the UK, only 26 would be suitable girlfriends for him.
The dull equation takes into account the number of women aged 24 to 34, living in his home city of London, and who are single, meaning his chances of meeting his dream woman on a night out are slim.
The economics expert said: “There are 26 women in London with whom I might have a wonderful relationship. So, on a given night out in London there is a 0.0000034% chance of meeting one of these special people. That’s a 1 in 285,000 chance, so it’s not great.”
The puzzling Drake equation reads: N =" R*" x Fp x Ne x Fi x Fc x L, and helped pioneering scientist Professor Drake to predict that there could be 10,000 civilizations in our galaxy.
Mr. Backus simply replaced the original equation with his own criteria for a dream date, which included the percentage of women likely to find him attractive, and the number of girls aged 24-34 in London. He said: “The research may sound depressing to people looking for love, but the good news for singles is, it’s probably not your fault!”
56. Mr. Backus’ discovery in this passage is mainly concerned about ______.
A. whether there exists life out of our planet
B. the possibility of his being able to find love
C. how to get rid of singledom
D. what math can do to serve our daily life
57. What does Mr. Backus think of the result of his research?
A. Optimistic.     B. Depressing.      C. Unrealistic.     D. Exciting.
58. What can we learn from the first paragraph?
A. Mr. Backus’ major research field is “singledom”.
B. Mr. Backus found a girlfriend three years ago.
C. Mr. Backus’ new thesis will surely be well received.
D. Mr. Backus has been searching for love for long.
59. By “the good news for singles” in the last sentence, Mr. Backus probably mean _____.
A. you don’t have to blame yourself for remaining single
B. maybe the discovery is not reliable at all
C. the result was based on his own criteria
D. there might be more dream date out of London
60. Which of the following statements is true?
A. This passage could be published in a scientific magazine.
B. The passage intends to prove there are other civilizations.
C. The passage writer doesn’t really understand the Drake equation.
D. Most women in London are not suitable for university teachers.
