Theyre not quite the flimsy red-and-blue-cellophane (玻璃纸) getups that they used to be, but the Sony and Panasonic models still require you to wear a pair of shades
9、to observe the effect. How can TV manufacturers convince you that seeing shows in 3-D is worth the annoyance of having to wear a pair of specs (眼镜)?The first way is by making the technology way better. After all. 3-D entertainment is nothing new. The early 1950s were flooded with 3-D movies, and the
10、 technology has made an occasional comeback ever since. Each time, though, its done in by the same complaints: poor image quality and headaches and eyestrain from extended viewing. Early reviews of the new models from Sony and Panasonic suggest theyve solved the problem. Both use glasses that contai

22、35-year-old mystery of why fertilizers decrease biodiversity has finally been solved. The secret? They increase competition for sunlight. Adding fertilizers 1o grasslands increases the productivity of plants, but leads to a major drop in biodiversity.The amount of nitrogen(氮) and phosphorus(磷) avail
23、able to plants has doubled in the last 50 years, but the reason why this has harmed diversity has not been easy to answer. The debate has centred on whether fertilizers increase competition above or below ground-for sunlight or soil resources?To resolve the argument, Yann Hautier and Andy Hector fro
24、m the University of Zurich, Switzerland built their own experimental plant community from scratch. Hautiers team grew 32 plant communities for tour years, before transferring them to a glass house. Each community comprised four different sets of six species. Half were fertilized, the others were lef
25、t unfertilized. Half of each of these sets had light added, using a system of three fluorescent tubes that were raised as the canopy grew, while the other half were left to grow in normal light conditions.After two years, the sets that were fertilized in normal light conditions showed a significant
26、increase in productivity anti biomass, but lost around one-third of their species diversity compared to the unfertilized groups. Those that were fertilized and given additional light showed no significant loss of diversity.To uncover whether underground competition for root space had any influence o
27、n biodiversity, the team added two new species of plant at the beginning of the second year. The roots of half these plants were contained in plastic tubes, which prevented any below-ground competition: the other half were left exposed.Removing below, ground competition from fertilized plots had no
28、detectable impact on the mortality (死亡率) of the seedlings (幼苗), compared to those that were exposed to full root competition, says Hautier.“In the fertilized groups without additional light, there was no difference with or without the root-tube-they died both ways. Even if we remove competition belo
29、w ground, these plants are unable to grow. “Drew Purves, a computational ecologist from Microsoft Research Cambridge is impressed with the teams findings. “This is a rare example of a simple experiment providing an unambiguous answer to an important ecological question. If these results are general
30、to temperate grasslands-which seems likely-then we can start to develop more targeted policies to offset (补偿, 抵消) one of the most important sources of diversity loss in grasslands. /（分数：15.00）(1).The debate on the reason why fertilizers decrease biodiversity has centred on（分数：3.00）A.whether they can
31、 increase the amount of nitrogen and phosphorus available to plants.B.whether they increase the competition between plants for sunlight or for soil resources.C.whether adding fertilizers can really increase plant productivity.D.whether the biodiversity drops due to the fertilizes or some plants die
32、of other reasons.(2).What did Hauntiers team do in their study?（分数：3.00）A.They grew 32 plant communities for tour years and then transferred them to a house.B.They grew four sets of six different species and fertilized them.C.They add light to halt of these sets, and left the other half growing in n

37、loss.Is the Internet Broken?Googles Gmail system, which serves millions of customers around the world, shut down yesterday. Twitter, the micro-blogging service used by tens of millions of people, went off-line last month. It blamed the trouble on a malicious programmer in Russia who was trying to sh

It is astonishing the local actions of a small number of programmers call bring an entire Internet service to its knees, but that have been the case.The Internet as it is set up now operates at three levels. The first is the servers that store da
39、ta and content for use by customers. Google and other large companies keep massive server farms. These are well-protected from outside programmers by sophisticated software, but clearly that does not always work. The protection devices may fail more and more often as hackers get more skillful.The se
40、cond part of the Interact is the “pipes“ that carry data, video, e-mail messages, and text of websites from companies such as Google, Yahoo!, and Twirler, that make up Interact content and services to customers. Some of these“ pipe“ providers, specifically telecom and cable companies, are already co
41、mplaining that the amount of data that they have to move is rising too rapidly for them to accommodate. Video files, which are particularly large, have posed significant problems to cable companies.The last piece of the Interact is the end user, the companies and consumers who have tire PCs. Pervers
42、ely, these PCs are also the tools by which hackers build malicious code that they send out to compromise the effectiveness of the servers to destroy the data transport system which is at the core of the worldwide webs operations.The problem of online outages is as old as the internet itself, AOLs di
43、al-up 56k service would go down regularly in the mid-1990s. The company did not have enough modems to keep up with demand.The Internet for the last decade may not be the Internet for tire future. The prophylactic software that was meant to protect the web is less effective. Like anything else that i
