They can be as innocent as meeting announcements, but in a growing number of cases the language is meant to sh
17、ock. Its not uncommon, for instance, to see lewd (淫荡的) references to professors sexual preferences scrawled across a path or the mention of the word Nig that African-American students say make them feel uncomfortable.In response, officials and students at schools are now debating ways to lead their
18、communities away from forms of expression that offend or harass (侵扰). In the process, theyre butting up against the difficulties of regulating speech at institutions that pride themselves on fostering open debate.Mr. Bennet of Wesleyan says he had gotten used to seeing occasional chalkings filled wi
19、th four-letter words. Campus tradition made any horizontal surface not attached to a building a potential billboard. But when chalkings began taking on a more threatening and lewd tone, Bennet decided to act. “This is not acceptable in a workplace and not acceptable in an institution of higher learn
20、ing,“ Bennet says. For now, Bonnet is seeking input about what kind of message-posting policy the school should adopt. The student assembly recently passed a resolution saying the “right to speech comes with implicit responsibilities to respect community standards.“Other public universities have con
21、fronted problems this year while considering various ways of regulating where students can express themselves. At Harvard Law School, the recent controversy was more linked to the academic setting. Minority students there are seeking to curb what they consider harassing speech in the wake of a serie
22、s of incidents last spring.At a meeting held by the “Committee on Healthy Diversity“ last week, the schools Black Law Students Association endorsed a policy targeting discriminatory harassment. It would trigger a review by school officials if there were charges of “severe or pervasive conduct“ by st
23、udents or faculty. The policy would cover harassment based on, but not limited to, factors such as race, religion, creed, sexual orientation, national origin, and ethnicity (种族划分).Boston attorney Harvey Silverglate, says other schools have adopted similar harassment policies that are actually speech
24、 codes, punishing students for raising certain ideas. “Restricting students from saying anything that would be perceived as very unpleasant by another student continues uninterrupted,“ says Silverglate, who attended the Harvard Law town meeting last week.（分数：10.00）(1).What is the typical scene found
25、 in the campus of Wesleyan University?（分数：2.00）A.Pieces of chalk are scattered everywhere on the ground.B.There are some meeting announcements on the billboard.C.All kinds of messages are written on the paths.D.Some people are shocked by the meeting announcements.(2).From the passage we can see that
26、 _.（分数：2.00）A.officials and students are debating whether they should have free speechB.in the past decade, people did not have any freedom of speechC.some students are attacked politically as targetsD.officials and students are discussing ways of avoiding offending messages(3).Mr. Bennet _.（分数：2.00

30、city.五、Passage 2(总题数：1，分数：10.00)To get from Kathmandu to the tiny village in Nepal, Dave Irvine-Halliday spent more than two days. When he arrived, he found villagers working and reading around battery-powered lamps equipped with light-emitting diodes, or LEDs-the same lamps he had left there in 200
31、0.Irvine-Halliday, an American photonics engineer, was not surprised. He chose to use LED bulbs because they are rugged, portable, long-lived, and, extremely efficient. Each of his lamps produces a useful amount of illumination from just one watt of power. Villagers use them about four hours each ni
32、ght, then top off the battery by pedaling a generator for half an hour. The cool, steady beam is a huge improvement over lamps still common in developing countries. In fact, LEDs have big advantages over familiar incandescent (白炽的) lights as well-so much so that Irvine-Halliday expects LEDs will eve
33、ntually take over from Thomas Edisons old lightbulb as the worlds main source of artificial illumination.The dawn of LEDs began about 40 years ago, but early LEDs produced red or green glows suitable mainly for displays in digital clocks and calculators. A decade ago, engineers invented a semiconduc
34、tor crystal made of an aluminum compound that produced a much brighter red light. Around the same time, a Japanese engineer developed the first practical blue LED. This small advance had a huge impact because blue, green, and red LEDs can be combined to create most of the colors of the rainbow, just
35、 as that in a color television picture.These days, high-intensity color LEDs are showing up everywhere such as the traffic lights. The reasons for the rapid switchover are simple. Incandescent bulbs have to be replaced annually, but LED traffic lights should last five to yen years. LEDs also use 80
36、to 90 percent less electricity than the conventional signals they replace. Collectively, the new traffic lights save at least 400 million kilowatt-hours a year in the United States.Much bigger savings await if LEDs can supplant Mr. Edisons bulb at the office and in the living room. Creating a white-
37、light LED that is energy-saving, cheap and appealing has proved a tough engineering challenge. But all the major lightbulb makers-including General Electric, Philips, and Osram-Sylvania-are teaming up with semiconductor manufacturers to make it happen.（分数：10.00）(1).From the first paragraph, we can s
38、ee that Dave Irvine-Halliday _.（分数：2.00）A.is a mountain climberB.went to that village to repair the lampsC.found the villagers were using the lamps he had given themD.has visited the small village several times(2).The author implies that villagers liked LED bulbs very much, because they _.（分数：2.00）A
39、.were given by Irvine-HallidayB.are ruggedC.are cheapD.are easily-recharged(3).What does Irvine-Haltiday think of LEDs?（分数：2.00）A.They are cool and steady, but rugged.B.They will replace Edisons lightbulbs someday.C.They are easily maintained.D.They are very cheap.(4).Which of the following statemen
40、ts does not agree with the facts in the passage?（分数：2.00）A.The displays in digital clocks and calculators ape just produced by early LEDs.B.Irvine-Halliday believes that LED will certainly become the worlds main source of artificial light.C.A decade ago, engineers developed red and blue LEDs, which
41、were regarded as a milestone in this research.D.It is the blue LED developed by a Japanese engineer that had a great impact on the research process.(5).The passage implies that _.（分数：2.00）A.LED bulbs are still expensive at presentB.the task of making LED the main source of artificial light is too di
42、fficultC.LED traffic lights are used everywhere in the worldD.in order to fulfill the task of making LED the main light source, lightbulb makers have to work together with semiconductor manufacturers六、Passage 3(总题数：1，分数：10.00)Before high school teacher Kimberly Rugh got down to business at the start
43、 of a recent school week, she joked with her students about how shed had to clean cake out of the corners of her house after her 2-year-old sons birthday party. This friendly combination of chitchat took place not in front of a blackboard but in an E-mail message that Rugh sent to the 145 students s
44、hes teaching at the Florida Virtual School, one of the nations leading online high schools. The schools motto is “any time, any place, any path, any pace“.Floridas E-school attracts many students who need flexible scheduling, from young tennis stars and young musicians to brothers Tobias and Tyler H
45、eeb, who take turns working on the computer while helping out with their familys clam-farming business on Pine Island, off Floridas southwest coast. Home-schoolers also are well represented. Most students live in Florida, but 55 hail from West Virginia, where a severe teacher shortage makes it hard
46、for many students to take advanced classes. Seven kids from Texas and four from Shanghai round out the student body.The great majority of Florida Virtual Schooler- 80 percent are enrolled in regular Florida public or private high schools. Some are busy overachievers. Others are retaking classes they
47、 barely passed the first time, The schools biggest challenge is making sure that students arent left to sink or swim on their own. After the school experienced a disappointing course completion rate of just 50 percent in its early years, Executive Director Julie Young made a priority out of what she
48、 calls “relationship-building,“ asking teachers to stay in frequent E-mail and phone contact with their students. That personal touch has helped: The completion rate is now 80 percent.Critics of online classes say that while they may have a limited place, they are a poor substitute for the face-to-f
49、ace contact and socialization that take place in brick-and-mortar classrooms. Despite opportunities for online chats, some virtual students say theyd prefer to have more interaction with their peers.Students and parents are quick to acknowledge that virtual schooling isnt for everyone. “If your childs not focused and motivated, I can only imagine it would be a nightmare,“ says Patricia Haygood of Orlando, whose two daughters
