as smoking marijuana(大麻). That is the claim of psychologists who have found that tapping
away on a mobile phone or computer keypad or checking_them_for_electronic_messages
_temporarily_knocks_up_to_ten_points_off_the_user"s_IQ.
This rate of decline in intelligence compares unfavorably with the fourpoint drop in IQ
associated with smoking marijuana, according to British researchers, who have labeled(把
……称为)the fleeting phenomenon of enhanced stupidity as "infomania"．
The noticeable drop in IQ is believed to be the result of the constant distraction of "always
on" technology when employees should be concentrating on what they are paid to do. Infomania
means that they lose concentration as their minds remain fixed in an almost permanent state of
readiness to react to technology instead of focusing on the tasks in hand.
The brain also finds it hard to deal with keeping lots of tasks in motion at once, reducing its
overall effectiveness. While modern technology can have huge benefits, excessive(过度的)use
can be damaging not only to a person"s mind, but to his or her social life.
Eighty volunteers took part in clinical trials on IQ damage and 1,100 adults were interviewed.
More than six in ten people polled admitted that they were addicted to checking their emails
and text messages so that they examined workrelated ones even when at home or on holiday.
Half said that they always responded immediately to an email and one in five would interrupt a
meeting to do so.
Furthermore, infomania is having a negative effect on work colleagues, increasing stress and
disagreeing feelings. Nine out of ten polled thought that colleagues who answered emails or
messages during a facetoface meeting were extremely rude. Yet one in three Britons believed
that it was not only acceptable, but actually diligent and efficient to do so.
B. The person who has a higher IQ enjoys checking electronic messages.
C. The person who has a lower IQ enjoys checking electronic messages.
D. A person"s IQ is ten points higher if he or she always checks electronic messages.
B. People with infomania are addicted to smoking marijuana.
C. People with infomania can"t respond to technology immediately.
D. People with infomania can"t concentrate on their tasks in hand.
B. about 670 interviewees responded to an email immediately
C. about 50 taking part in clinical trials on IQ were addicted to checking emails
D. about 16 taking part in clinical trials on IQ refused to answer emails immediately
B. Modern technology can damage a person"s mind.
C. The regular use of text messages and emails can harm your IQ.
D. Electronic messages have side effects on the user"s life.

sense a user"s mood.Researchers at Queen"s University in Belfast hope to complete the 10
million Euro project for an emotionsensitive computer within four years.
The aim is to enable computers to think and behave more like humans.The Europewide
project is being led by the university"s School of Psychology and involves 160 researchers
from 27 institutions.The university"s researchers developed the scheme and signed the
contract with the European Commission.The academics said the work will build upon attempts
to create "multimodal interfaces (多模式界面)" which allow machines to sense and respond
to the moods of the user.
Programme leader Professor Roddy Cowie said while it sounds like science fiction, computers
which respond to human emotion will appear in the future."At the moment, our use of computers
is limited by the fact that we need a keyboard and a screen to access them," he said."It would make
a big difference if we could interact with them by speaking normally-perhaps through a microphone
and a transmitter (传感器)．" But emotion is part of normal speech, and experience has shown that
most users are deeply uncomfortable with speech interfaces that ignore it-too uncomfortable to use
them very much."If we can make computers more intuitive (富于直觉的) and expressive, and also
less challenging to use, there is great potential to let people make fuller use of information technology."
The emotionsensitive computer would have its own "personality" and establish a social relationship
with the user."It"s a fair bet that in 30 years" time, emotionsensitive interfaces will be as much part of
life as windowandmouse interfaces are now," said Professor Cowie.The project team believes such
computers will play a major role in teaching and learning.
B．It can create a 10 million Euro profit.
C．It is led by a Southern Ireland team.
D．It has been completed within four years.
B．Through a keyboard.
C．Through the voice of users.
D．Through multimodal interfaces.
B．is determined by his own personality
C．plays an important role in normal speech
D．makes people uncomfortable when one is speaking
B．It will be difficult for people to use emotionsensitive computers.
C．Emotionsensitive computers have been widely used in teaching.
D．It will be common for people to use emotionsensitive computers in the future.
With the Tesla Roadster and other plugin (插入式) electric vehicles hitting the road, demand isgrowing for accessible refueling points to recharge them. Carbon Day Automotive, a Chicagobased
company, has now demonstrated a solarpowered recharging point, known as the Solar PlugIn Station,
which lets motorists easily charge their cars using electricity that has been produced without any
environmental damage.
The Solar PlugIn Station has gone on show in Chicago as part of the city"s bid to host the 2016
Olympic Games. According to Carbon Day Automotive, the Solar PlugIn Station on show in Chicago is
part of the vital infrastructure(基础设施) required for electric vehicles in Chicago and was the focus of
a recent visit by the International Olympic Committee.
These solarpowered electricity points will be used daily to fuel the city"s electric vehicles with power from the sun. By producing the electricity from pollutionfree solar cell, the CO2 emissions are reduced to
zero. "Solar energy and e
lectric vehicles ar
e a partnership that is one more step to reducing our dependence on foreign oil," says Richard Lowenthal, CEO of Coulomb Technologies. Coulomb
Technologies recently developed the components (部件) required for individual recharging stations,
marketed as ChargePoint Networked Charging Stations. Carbon Day Automotive is the Midwest
distributor for the ChargePoint stations. The Solar PlugIn Station consists of giant solar panels (电池板)
that shade the tiny ChargePoint Networked Charging Station.The solar panel is connected to an
underground battery pack, ready for everyday refueling.
"Without these stations it would be like driving around in a traditional car without the availability of
gas stations," says Scott Emalfarb, CEO at Carbon Day. "The day of true plugin electric vehicles will be
here sooner than most people realize and the world needs to be ready to accommodate them."

they are stealing your corporate secrets.
Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks
from outside the buildings that house them. A recent study in the UK, sponsored by RSA Data Security,
found that two-thirds of organizations with wireless networks were risking their data in this way. Security
experts patrolled (巡逻) several streets in the City of London seeking evidence of wireless networks in
operation.
Of 124 that they identified, 83 were sending data without encrypting（加密）them. Such data could
readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few
pieces of software that can be freely downloaded from t
he Internet.The data could include sensitive company documents containing valuable information. Or they could
be e-mail identities and passwords that could be used by hackers to log into corporate networks as if
they were legal users.
Most companies using wireless networking technology do not take even the simplest of measures to
protect their data. Nearly all wireless network technology comes with some basic security features that
need only to be activated (激活) in order to give a minimum level of security, for example, by encrypting
the data being passed over the network.
Raymon Kruck, business development manager at Check Point Software, a security technology
specialist, believes this could be partly a psychological problem. People see the solid walls of their
building as safeguards and forget that wireles
s networks can extend up to 200 meters beyond physical walls.
Companies without any security at all on their wireless networks make it ridiculously easy for hackers
to break in. Switching on the security that comes with the network technology should be automatic. Then
there are other basic steps a company can take, says Mr. Kruck, such as changing the passwords on the
network from the default (默认) setting.
Companies can also install firewalls, which form a barrier between the internal network and the public
Internet. They should also check their computer records regularly to spot any abnormal activity, which
might betray the presence of a hacker.
B. depended on wireless computer networks
C. were exposed to drive-by hacking
D. were unaware of the risk of wireless hacking
of the following is NOT considered in the study?B. The number of wireless computer networks identified.
C. The way in which data are sent and received.
D. The way in which data are hacked and stolen.
B. password security programs
C. illegal-user detection
D. firewall
B. changes in user"s awareness
C. users" psychological health

opinions. But recent data has indeed shown cognitive (认知的) ability to be higher in some countries
than in others. What"s more, IQ scores have risen as nations develop—a phenomenon known as the
"Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn
effect, including education, income, and even non-agricultural labor. Now, a new study from researchers
at the University of New Mexico offers another interesting theory: intelligence may be linked to
infectious-disease rates.
[2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human
body". Brainpower consumes almost up to 90 percent of a newborn"s energy. It"s clear that if something
affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts
of the globe, the biggest threat to a child"s body -- and therefore brain—is parasitic (由寄生虫引起的)
infection. These illnesses threaten brain development __________. They can directly atta
ck live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block
nutritional intake. They can rob the body"s cells for their own reproduction. And then there"s the energy
channeled (输送) to the immune system to fight the infection.
[3] Using data on national "disease burdens" (life years lost due to infectious diseases) and average
intelligence scores, the authors found they are closely associated. The countries with the lowest average
IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease
burdens top the IQ list.
[4]If the study holds water, it could be revolutionary for our unde
rstanding of the still-confusing variation in national intelligence scores.

being taken seriously by many researchers.
This suggested future for the "red planet" will be the main topic for discussion at an international
conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction
writers will attend the event. It comes as NASA is preparing a multibilliondollar Mars research
programme. "Turning Mars into a little earth has long been a topic in science fiction," said Dr Michael
Meyer, NASA"s senior scientist for astrobiology (太空生物学). "Now, with scientists exploring the
reality, we can ask what are the real possibilities of changing Mars."
Most scientists agree that Mars could be turned into a little earth, although much time and money
would be needed to achieve this goal.
But many experts are shocked by the idea.“We are destroying our own world at an unbelievable
speed and now we are talking about ruining another planet, ” said Paul Murdin, of the Institute of
Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they
will find Martian life forms.Europe and America"s robot explorers have found proof that water, mixed
with soil, exists in large amounts on the planet.
In addition, two different groups of scientistsannounced on March 28 that they had found signs of
methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and
could be produced by microbes (微生物) living in the red planet"s soil.
But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be
put in danger by the little earth project. "Before we have even discovered if there is life on Mars, we are
talking about carrying out projects that would destroy all these native life forms, all the strange microbes
that we hope to find buried in the soil," said Dr Pratt.This view is shared by Monica Grady, a planetary
scientist at the Natural History Museum, London. "We cannot risk starting a global experiment that would wipe out the precious information we are looking for." she said, "This is just wrong."
B. the necessity of changing Mars
C. Mars supporting life
D. finding water in the Mars
B. The project will cost too much money and work.
C. We would ruin Mars.
D. We are destroying our own world at an unbelievable speed.
B. the project will have little effect on the native life forms supposed to live on the Mars
C. Monica Grady is in favour of carrying out the little earth project
D. the idea turning Mars into a little earth is nothing but a science fiction
B. Scientists found signs of methane in the Martian atmosphere.
C. Scientists found a lot of good soil on the Mars.
D. Scientists found some creatures living on the Mars.
