3、eges After midnight on a rainy night last week in Chapel Hill, N.C., a large group of sorority (女学生联谊会 ) women at the University of North Carolina squeezed into a basement bar. Bathed in a colorful glow, they splashed beer from pitchers, traded jokes and shouted lyrics to a Taylor Swift heartache an

4、them thundering overhead. As a night out, it had everything-except guys. North Carolina, with a student body that is nearly 60 percent female, is just one of many large universities that at times feel weirdly like womens colleges. Women have represented about 57 percent of enrollments at American co

5、lleges since at least 2000, according to a recent report by the American Council on Education. Researchers there cite several reasons: women tend to have higher grades; men tend to drop out in disproportionate numbers; and female enrollment leads further among older students, low-income students, an

6、d black students. The Effects of the Sexual Imbalance In terms of academic advancement, this is hardly the worst news for women-its a sign of female achievement. But surrounded by so many other successful women, they often find it harder than expected to find a date on a Friday night. Jayne Dallas,

7、a senior studying advertising who was seated across the table, complained that the population of male undergraduates was even smaller when you looked at it as a dating pool. “Out of that 40 percent, there are maybe 20 percent that we would consider, and out of those 20, 10 have girlfriends, so all t

8、he girls are fighting over that other 10 percent,“ she said. Needless to say, this puts guys in a position to play the field, and tends to mean that even the ones willing to make a commitment come with storied romantic histories. Rachel Sasser, a senior history major at the table, said that before s

9、he and her boyfriend started dating, he had “hooked up with a least five of my friends in my sorority-that I know of“. These sorts of romantic complications are hardly confined to North Carolina, an academically rigorous school where most students spend more time studying than socializing. The gende

10、r imbalance is also pronounced at some private colleges, such as New York University and Lewis especially when dear old Mr. Priestly said, “Thats good but you need to pause and to put feeling and emotion into it.“ Eleven year old boys are unwilling to express feelings. The Saturday of the festival c

11、ame and I went there on the bus (my parents never had a ear). I gave it my best shot but there were other children there who were more polished or experienced than I was and they scooped all the prizes. So I had to return to school on Monday and tell Mr. Priestley and the class that I had not won. I

12、 was then, and still am, very competitive so it felt like a failure to me. We did not have Mr. Priestley again after that year and I never thanked him for that intervention. It is too late to do so now. In my work I go around the world giving keynote talks on leadership and innovation and I often ad

13、dress large, prestigious audiences. Part of the reason that I can do that is because one teacher took the initiative and gave me a challenge. He asked me to do something I had never done and helped me to learn how to do it. Education is not about league tables or exam results. It is about opening do

14、ors for people and showing them rooms that that would otherwise be hidden. If we can challenge children to try things and to learn what they can achieve then maybe one day we will be remembered with the gratitude that I hold for Mr. Priestley. 53 In the “elocution lessons“, the author was taught the

15、 skills of how to _. （ A） be a leader （ B） write a poem （ C） be a wrestler （ D） give a speech 54 Mr. Priestley wanted the author to take part in the festival most probably because _. （ A） the author was the best in class （ B） the author didnt have confidence in himself （ C） the author wasnt good at

16、expressing himself （ D） the author needed to be motivated 55 The author found it the most embarrassing that _. （ A） he had to practice the poem in front of the class （ B） he had to put feeling and emotion into the poem （ C） his mistakes were pointed out by Mr. Priestley （ D） his practice was appreci

17、ated by Mr. Priestley 56 The author gave it his “best shot“ because _. （ A） he was very competitive then （ B） he was grateful to Mr. Priestley （ C） his classmates had great faith in him （ D） it took him a long time for preparation 57 It is most likely that the author wants to _. （ A） tell a story ab

18、out teaching （ B） study a teaching method （ C） enlighten parents （ D） instruct students 57 Humans on the earth have had an over-inflated view of how far the planets atmosphere extends into space. It turns out that the ionosphere (电离层 ), the layer of electrically charged particles that comprises the

19、outer atmosphere, is thinner than expected-and cooler. Understanding the shape and size of the ionosphere is an important first step in figuring out how particularly dense regions within it may distort radio, radar and navigation signals. Such distortions can make communications and satellite-based

20、systems less reliable. “In order to predict how severe those distortions will be, its necessary to know how big those structures in the ionosphere are and where they exist,“ Roderick Hellis, with the Space sciences Center at the University of Texas in Dallas, told Discovery News. Hellis and his coll

21、eagues have been using a suite of NASA instruments called CINDI, which fly on the U.S. Air Force Communication/Navigation Outage Forecast System (C/NOFS) satellite between 250 miles and 530 miles around the planets equator. The researchers never expected to encounter the edge of Earths ionosphere at

22、 those altitudes, but that is exactly what happened during the summer of 2008, a time when the solar activity was unusually weak. “It was a real combination of low solar activity and the satellites range,“ Hellis said. “We didnt expect to be able to look at the top of the ionosphere in all places.“

23、Computer models based on previous research had predicted the ionosphere to be about 370 miles above Earth at night and about 620 miles up during the day-the variation due to temperature and other factors. Instead, the CINDI team discovered that the transition between the ionosphere and space was abo

24、ut 250 miles above Earth at night and about 500 miles up during the day. The ionosphere is primarily caused by extreme ultraviolet energy from the sun. “Its powerful enough that those photons (光子 ) can ionize (使 电离 ) atoms in Earths upper atmosphere,“ said David Hathaway, a solar physicist at NASAs

25、Marshall Space Flight Center in Huntsville, Ala. “When you have a geomagnetic disturbance or a solar flare going off, you can get an ionosphere that is uneven, which can cause problems with radio signals and GPS satellite signals, which have to pass through.“ The findings were presented at the annua

26、l American Geophysical Union conference in San Francisco last month. CINDI is an acronym for Coupled Ion Neutral Dynamics Investigation. The device works by separately measuring ionized and neutral particles at altitudes where the Air Force satellite flies. A similar device is on another polar-orbit

27、ing Air Force spacecraft. The researchers hope to keep using CINDI as solar activity picks up in the suns new 11-year cycle. The next solar maximum is expected in late 2011 or 2012. 58 We have always had a misconception about_. （ A） how far away the upper edge of the ionosphere is （ B） how many part

28、icles comprise the ionosphere （ C） how long the ionosphere has been existing （ D） how the ionosphere extends into space 59 In order to predict distortions, scientists need to_. （ A） improve the severity of radio, radar and navigation signals （ B） improve the accuracy of the satellite-based systems （

29、 C） study the charged particles in the ionosphere （ D） study the thick regions in the ionosphere 60 In 2008, scientists encountered the top of the ionosphere all_. （ A） thanks to the weak solar activity （ B） because of the advanced CINDI （ C） by chance （ D） as predicted 61 Its pointed out by David H

30、athaway that _. （ A） a solar flare must pass through the ionosphere （ B） a solar flare must pass through the GPS satellite signals （ C） radio signals must pass through the ionosphere （ D） radio signals must pass through a geomagnetic disturbance 62 CINDI is a device most probably for _. （ A） civil p

31、urpose （ B） military use （ C） telecommunication （ D） weather forecast 三、 Part V Cloze (15 minutes) Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A, B, C and D. You should choose the ONE that best fits into the passage. 62 While the worlds flu
