The International Agency for Research on Cancer(IRIC)，part of the United Nations’ World Health Organization(WHO), claims that radiofrequency electromagnetic fields(RF/EMF)（射频电磁场）is possibly carcinogenic(致癌的) to humans. The main sources of RF/EMF are radios, televisions, microwave ovens, cellphones, and Wi-Fi devices.

Even if we want to, we can’t eliminate（消除） our exposure or our children’s, to RF/EMF. But, we many need to limit that exposure, when possible. That was among the conclusions of a controversial survey article published in the Journal of Microscopy and Ultrastructure entitled “Why children absorb more microwave radiation than adults: The consequences.” From an analysis of relevant studies, the authors argue that children and adolescents are at considerable risk from devices that radiate microwaves. The following points were offered for consideration:

●    Fetuses(胎儿) are even more vulnerable than children. Therefore pregnant women should not expose their fetus to microwave radiation.

●    Adolescent girls and women should not place cellphones in their bras or in hijabs (headscarf)

●    Cellphone manual warnings make clear an overexposure problem exists.

●    Government warnings have been issued but most of the public are unaware of such warnings.

●    Wireless devices are radio transmitters, not toys. Selling toys that use them should be monitored more closely.

  Children and fetuses absorb more microwave radiation, according to the authors, because their bodies are relatively smaller, their skulls are thinner, and their brain tissue is weaker.

     This is not a call to throw out all electronic devices. However, at the very least, it should open up the discussion about different safety levels for adults versus children. Hopefully more studies will be done to check or contradict the assumptions so far. In the meantime, are the government’s current regulations adequate? The exposure levels they warn against haven’t seemed to have been updated for more than 19 years.

In a Network World opinion article ominously titled “Is Wi-Fi killing us … slowly?” columnist Mark Gibbs makes the point that “…laws and warnings are all very well but it’s pretty much certain that all restrictions on products that use microwave technology will error(犯错) on the safe side; that is, the side that’s safe for industry, not the side of what’s safe for society.” Gibbs then added this ominous closing question, “Will we look back (sadly) in fifty or a hundred years and marvel at how Wi-Fi and cellphones were responsible for the biggest health crisis in human history?”

I visited the zoo yesterday, but I was very  unhappy and angry about the things that I saw. The large animals were in small    (1)  . The lion was walking    (2)  and forth. It was completely  bored. The tiger fell    (3)  all the afternoon.

I saw many people     (4)  the fish. They were throwing   rice and meat    (5)  the pond, which could   kill the fish,     (6)  no one tried to stop them.   When I     (7)  a drink at the zoo restaurant, the waiter served me    (8)  .   Outside the restaurant, the rubbish bins were full and rubbish was  blown everywhere. It seems     (9)  the zoo  doesn't look    (10)  the animals or the visitors very well.

The world faces a future of people speaking more than one language, with English no longer seen as likely to become      41, a British language expert says in a new analysis. “English is likely to      42one of the world’s most important languages for the foreseeable future, but its future is more      43and complex—than most people appreciate,” language researcher David Graddol said. He sees English as likely to become the “first among equals” rather than having the global field to itself. “Speakers, who only use English, of any      44of English—American or British—will      45increasing difficulty in employment and political life, and are likely to become confused by many aspects of the society and culture around them,” Graddol said.

The     46 of the world’s population that speaks English as a native language is decreasing, Graddol reported in an issue of the journal Science. The idea of English becoming the world language to the     47of others “is past its sell-by date,” Graddol said. Instead, he said, its major 48will be in creating generations who use more than one language.

A multilingual(使用多种语言的) population is the     49  in much of the world and is becoming more common in the United States. Indeed, the Census Bureau reported last year that nearly one American in five speaks a language other than English at home, with Spanish leading, and Chinese      50 rapidly. The diversity of language, in turn, has helped to make English the nation’s official language.
