With only a click of the mouse, rumors can be forwarded between microblogs very quickly. As an example, recently, perceptive netizens discovered that some photos displayed on microblogs depicting Beijing’s June rainstorm had actually been fabricated.

Sina.com is one of the major internet portals(门户网站) in China with hundreds and thousands of users, and a majority of celebrities and renowned citizens have their microblog accounts on this portal. As recently as six months ago, the website decided to establish a specialized team to verify rumors and provide accurate information for its users. Tan Chao is in charge of the team.

“Before I took the job, I usually couldn’t identify what information was real and what was fake. But during the rumor verification process, we discovered that a lot of information was false, including fake photos, fake news stories and rumors that had been spread through microblogs.”

It‘s not just website portals which are taking on fact-checking responsibilities, but also a number of civic-minded netizens, who recently set up a Rumor Verification Federation on Sina.com’s microblog system to help netizens identify fake information online.

  Dianzizheng is the team leader of the federation. He says they’ve publicized more than 150 pieces which refute rumors, which attracted more than 10 thousand visitors within two months.

  “We live in an age of new media, so we can’t use the old methods to verify rumors. We can’t wait for the media to verify the facts with related administrative departments and then release a formal announcement. We can’t allow rumors to run rampant and then deal with it, we need to fight rumors while they’re spreading. I think that this is the best way to deal with rumors nowadays.”

  Some experts say this demonstrates the advantages of the internet compared to other traditional media. The open platform allows information to be examined and clarified by netizens. But experts like Ding Wenguo, President of the Journalism and Communication College at the China University of Political Science and Law says this self-correction function of the internet is still quite limited.

  “It’s still quite difficult to tell which information is true in such an open environment by just reading a number of different opinions on the same issue. This is something which we need to pay attention to. If society is deluged with too much false information, and it’s allowed to spread in such a fast manner, then people will be suspicious of all kinds of information including important information from authorities. It also exacerbates(恶化) problems relating to social communications and mutual-understanding, which in turn harms society as a whole.”

  Experts suggest that the government should react more quickly in the internet age. Once a rumor begins to spread, administrative departments should make announcements as early as possible to dispel rumors before they lead to bad outcomes.

单项选择题

转基因作物同普通植物的区别只是多了能使它产生额外特性的基因。早在1983年,生物学家就已经知道了怎样通过生物工程技术将外来基因移植到某种植物的脱氧核糖核酸中去,以便使它产生靠杂交方式根本无法获得的某种新的特性:抗除莠剂的特性、抗植物病毒的特性、抗某种害虫的特性等。用以移植的基因可来自任何生命体:细茵、病毒、昆虫等。
转基因作物目前在世界上已种植有1000万公顷左右,种植最多的是棉花、玉米和西红柿等。在实验室试种的还有莴苣、西瓜、稻谷等品种。试验的目的除了增产之外,还在于提高这些品种的抗病毒能力。
但同时也有专家担心转基因作物可能对环境有危险。比如在美国栽种的那种能抗虫害的玉米和棉花,可能加快出现一些更难对付的害虫。这类作物的所有分子都分泌出一些微量的“杀虫药”,一种像任何一种农药一样能选择杀死某些害虫的“雾剂”。尤其是那些能抗除莠剂的作物,它们一旦同野生状态下的“表姐妹”杂交之后,那些“表姐妹”也就会因此而成为除莠剂无法除掉的变种了。
对于这种技术,尽管还有些问题需要继续研究,但这确是人类9000年作物栽培史上一场空前的革命。

对文中所提供的信息,理解不准确的一项是______。

A.生物学家知道怎样通过转基因技术使作物产生抗除莠剂等特性不过十多年时间
B.转基因作物可能给环境带来危险是转基因技术研究中不容忽视的问题
C.野生植物同抗除莠剂作物杂交之后的变种已经给农业生产带来新问题
D.转基因是一种新的生物工程技术,它给作物栽培带来从未有过的根本改革
