Cell phones operate with radio frequencies,a form. of energy located on the electromagnetic spectrum between FM radio waves and the waves used in microwave ovens,radar,and satellite stations.Cell phones do not emit ionizing radiation,the type that damages DNA and is known to have the ability to cause cancer.
Cell phone technology works on a system of geographically separated zones called"cells".Each cell has its own "base station" that both receives and emits radio waves.When a call is placed from a cell phone,a signal is sent from the cell phone antenna to that cell's base station antenna.The base station responds to the cell phone signal by assigning the phone an available RF channel.When the RF channel is assigned,radio signals are simultaneously received and transmitted,allowing voice information to be carried between the cell phone and the base.The base station transfers the call to a switching centre, where the call can be transferred to a local telephone carrier or another cell phone.
6.There has existed argument about the link between cell phone and brain tumor()
7.The rapid growing number of cell phone users has been a great concern in the US()

Plomin's colleagues drew blood from two groups of 51 children each. They are all White living in six counties around Cleveland. In one group, the average IQ is 136. In the other group, the average IQ is 103. Isolating the blood cells, the researchers then examined each child's chromosome 6 (One of the 23 human chromosomes). Of the 37 land marks on chromosome 6 that the researchers looked for, one jumped out: a form. of gene called IGF2R occurred in twice as many children in high IQ group as in the average growth—32 percent versus 16 percent. The study concludes that it is this form. of the IGF2R gene, called allele 5, that contributes to intelligence.
Plomin cautions that "This is not a genius gene. It is one of many". (About half the differences in intelligence between one person and another are thought to reflect different genes, and half reflect different life experiences.)The gene accounts for no more than four extra IQ points. And it is neither necessary nor sufficient for high IQ: 23 percent of the average-IQ kids did have it, but 54 percent of genius kids did not.
The smart gene is known by the snappy name "insulin like growth factor 2 receptor" (IGH2R to its fun). It lets hormones like one similar to insulin dock with cells. Although a gene involved with insulin is not the most obvious candidate for an IQ gene, new evidence suggests it might indeed play the role. Sometimes when s hormone docks with the cell, it makes the cell grow; sometimes it makes the cell commit suicide. Both responses could choreograph the development of the brain. Scientists at the National Institutes of Health find that insulin can stimulate nerves to grow. And in rat brains, regions involved in learning and memory are chock full of insulin receptors.
Even though this supports the idea that IGF2R can affect the brain and hence intelligence, some geneticists see major problems with the IQ-gene study. One is the possibility that Plomin's group fell for what's called the chopsticks fallacy. Geneticists might think they've found a gene for chopsticks dexterity, but all they've really found is a gene more common in Asians than, say, Africans. Similarly, Plomin's IQ gene might simply be one that is more common in groups that emphasize academic achievement. "What if the gene they've found reflects ethnicity？" asks geneticist Andrew Feinberg of Johns Hopkins University. "I would take these findings with a whole box of salt".
As for how much of IQ comes from the genes and how much come from experiences,______.
A．scientists have reached an agreement
B．scientists' opinions vary
C．no genes have ever been identified
D．scientists have found many smart genes
The cooling off in demand threatens to cascade through the industry: The big six U.S. cell-phone carriers—Verizon Wireless, Cingular Wireless, AT＆T Wireless, Sprint PCS, Voice Stream, and Nextel Communications—are engaged in a fierce price war that imperils their timetables for becoming profitable, not to mention their efforts to whittle down their mountains of debt. As the carriers have begun to cut costs wireless equipment makers—companies such as Lucent, Nokia, and Ericsson have been left with a market that's bound to be smaller than they had anticipated. Handset makers have been insulated so far, but they, too face a nagging uncertainty. They'll soon introduce advanced phones to the U.S. market that will run on the new networks the carriers are starting up over the next year or two. But the question then will be: Will Americans embrace these snazzy data features and their higher costs—with the wild enthusiasm that Europeans and Asians have？
Long before the outcome in clear, the industry will have to adopt a new mind-set. "In the old days, it was all about connectivity." says Andrew Cole, an analyst with wireless consultancy Adventist. Build the network, and customers will come. From now on, the stakes will be higher. The new mantra: Please customers, or you may not survive.
To work their way out of this box, the carriers are spending huge sums to address the problem. Much of Sprint PCS's $3.4 billion in capital outlays this year will be for new stations. And in fact, the new high-speed, high-capacity nationwide networks due to roll out later this year should help ease the calling capacity crunch that has caused many consumer complaints. In the meantime, some companies are using better training and organization to keep customers happy. The nation's largest rural operator, Alltel (AT), recently reorganized its call centers so that a customer's query goes to the first operator who's available anywhere in the country, instead of the first one available in the customer's home area. That should cut waiting time to one minute from three to five minutes previously.
What is the text mainly about？
A．The bad service in the U.S. cell-phone industry.
B．The crisis in the U.S. cell phone industry.
C．The conflicts among cell-phone companies in the U.S.
D．The price of the U.S. cell-phone industry.
This kind of money troubles isn't strange to common families these days. In fact, it's hard to avoid news about the economy on the screen of the TV or the computers recently. It can seem a bit worry and some families are hit really hard.
For most people, the big problem is that things cost more at a time when they have less money to spend. But higher prices aren't the only problem. Many people are having a tough time making payments on some types of home loans.
Therefore, some families are cutting back on what they spend. For example, eating out less, staying home instead of going on vacation, moving to a less expensive house and so on.
However, as discouraging as things may seem now, the good news is that the economy always gets back on track after a while. Jobs may be hard to find, but the slow economy can open up new opportunities. The couple Devon babysat for might cut back on evening's out, but they could be interested in hiring her for after-school care. Perhaps it's time to sell her old toys and baby gear (设备) in the basement(地下室) or help others sell these items online if she is-good at it. She could charge them a fee to sell their old stuff(东西).
What does the underlined phrase in the first paragraph refer to？
A．Getting hurt.
B．Short of money.
C．Out of work.
D．Receiving less calls.
While it's true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to mm into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so called stem cells haven't begun to specialize.
Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells—brain cells in Alzheimer's, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few; if doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue.
It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can't be controlled, and may have unforeseen limitations; but if efforts to understand and master stem cell development prove successful, doctors will have a therapeutic tool of incredible power.
The same applies to cloning, which is really just the other side of the coin; true cloning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full fledged animal, genetically identical to its parent.
For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year.
Human cloning, on the other hand, may be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells: the potential to make healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true "miracle cure".
The writer holds that the potential to make healthy body tissues will ______.
A．aggravate moral issues of human cloning
B．bring great benefits to human beings
C．help scientists decode body instructions
D．involve employing surgical instruments
General Wesley Clark recently discovered a hole in his personal security—his cell phone. A resourceful blogger, hoping to call attention to the black market in phone records, made his privacy rights experiment on the general in January. For $ 89.95, he purchased, no questions asked, the records of 100 cell-phone calls that Clark had made. (He revealed the trick to Clark soon after. ) "It's like someone taking your wallet or knowing who paid you money", Clark says. "It's no great discovery, but it just doesn't feel right." Since then, Clark has become a vocal supporter of the movement to outlaw the sale of cell-phone records to third parties.
The U. S.'s embrace of mobile phones—about 65% of the population are subscribers—has far outpaced efforts to keep what we do with them private. That has cleared the way for a cottage industry devoted to exploiting phone numbers, calling records and even the locations of unsuspecting subscribers for profit. A second business segment is developing applications like anonymous traffic monitoring and employee tracking.
Most mobile phones are powerful tracking devices, with global-positioning systems (GPS) inside. Companies like Xora combine GPS data with information about users to create practical applications. One similar technology allows rental-car companies to track their cars with GPS. California imposed restrictions on the practice last year after a company fined a customer $ 3,000 for crossing into Nevada, violating the rental contract.
Other applications have not yet been challenged. For about $ 26 a month per employee, a boss can set up a "geofence" to track how workers use company-issued cell phones or even if they go home early. About 1,000 employers use the service, developed by Xora with Sprint-Nextel.
The companies selling those services insist that they care about privacy. AirSage, for example, gets data from wireless carriers to monitor drivers'cell-phone signals and map them over road grids. That lets it see exactly where gridlock is forming and quickly alert drivers to delays and alternative routes. The data it gets from wireless carrier companies are aggregated from many users and scrambled, so no one can track an individual phone. "No official can use the data to give someone a speeding ticket", says Cy Smith, CEO of AirSage.
Privacy advocates say that even with those safeguards, consumers should have a choice about how their information is used. Some responsibility, of course, rests with the individual. Since his data were revealed, Clark took his mobile number off his business cards. Wireless carriers also recommend that customers avoid giving out their mobile numbers online. But Clark insists that the law should change to protect our privacy, no matter how much technology allows us to connect. "One thing we value in this country", he says, "is the freedom to be left alone. "
The blogger publicized General Clark's phone record______.
A．to earn money from the internet
B．to blackmail the general for money
C．to play a trick on the general
D．to warn people of the information security
