US President Barack Obama may have just made life more difficult for cigarette makers, but he still
smokes every now and then in secret.
Obama, who has publicly struggled to quit smoking, said he still hasn"t completely kicked the habit
even after signing a law this week that will likely set tough new rules for the tobacco industry.
"As a former smoker I constantly struggle with it. Have I fallen off the wagon sometimes? Yes. Am
I a daily smoker, a constant smoker? No," Obama said at a news conference.
"I don"t do it in front of my kids, I don"t do it in front of my family. I would say that I am 95 percent
cured, but there are times where I mess up," he said.
The new law gives the US Food and Drug Administration the power to strictly limit the making and
marketing of tobacco products.
At a White House signing ceremony Monday, Obama said that he was among the nearly 90 percent
of smokers who took up the habit before their 18th birthday.
"Once you go down this path it"s something you continually struggle with, which is exactly why the
law we signed is so important because what we don"t want is kids going down that path in the first place,"
he said at the news conference.
Nearly 20 percent of Americans smoke and tobacco use kills about 440,000 people a year in the United
States due to cancer, heart disease, and other serious diseases.
B. had an accident
C. made Americans" life difficult
D. signed a law this week

Bruni on Feb. 8 or 9, media reported Monday. The report said that in December---less than a month after
Sarkozy met Bruni-he gave her a heart-shaped diamond engagement ring.
Carla Bruni, Italian singer, former model and girlfriend of France"s President Nicolas Sarkozy, holds the
hand of her son Aurelien while wearing a pink heart-shaped ring during a visit to the ancient Jordanian ruins
of Petra Jan. 5, 2008. French newspapers reported that Sarkozy would marry her early in February.
Sarkozy and his wife of 11 years, Cecilia, divorced in October. Their marital (婚姻) problems became
well known in May 2005 when she appeared in public at the side of event organizer Richard Attias.
A marriage to Bruni, a one-time star of the catwalks who is now a singer, would be Sarkozy"s third: He
divorced his first wife, Marie, in the late 80s-after he had met and befriended Cecilia. Political analyst
Dominique Moisi said that a Sarkozy proposal to Bruni could be part of his desire to head off any future
arguments, and the speed of their visit to the ancient Jordanian ruins of Petra Jan. 5, 2008 would fit with
his personality as a busy man in a hurry.
"Apparently, he"s going to marry her, so the problem will be behind him," Moisi said. "He will increase
the opportunities to travel with her, and to say to the French, "You see, I must remarry… You need a first
lady.""
Bruni, an Italian-born French citizen, has dated famous men including Mick Jagger and Donald Trump.
She has also reportedly been linked to singer Eric Clapton and actor Vincent Perez.
a. Long marriage to Cecilia
b. Visiting ruins with Bruni
c. Getting divorced from Marie
d. Giving Bruni a diamond ring
e. To marry the former supermodel
B. e-d-c-a-b

D. a-c-d-b-e
B. Sarkozy is good at balancing state and personal affairs
C. It is not easy for President Sarkozy to seek a new love
D. It is a doubt whether the marriage would have a bright future
B. show uncertainty about the former supermodel"s loyalty
C. imply that past experiences have little effect on a person
D. prove Bruni one of the most popular and attractive females
B. A third marriage to fail
C. France to have first lady
D. President"s new girl friend
interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic school in Lausanne,
Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person"s thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right band. He
could even talk as he watched the vehicle and guided it with his thoughts.
"Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to
give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals
from reaching the muscles," Tavella says. "Our system allows disabled people to communicate with external
world and also to control devices."
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp
(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized
wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react
to commands from the brain.
Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain
signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled
people can be grouped in two categories: communication, and controlling devices. One example is this
wheelchair."
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology
they can benefit from. And the other is to guarantee that they can use the technology over long periods of
time.
B. link the human brain with computers
C. help the disabled to recover
D. control a person"s thoughts
B. By talking to the machine.
C. By moving his hand.
D. By using his mind.
B. computer→cap→scalp→wheelchair
C. scalp→cap→computer→wheelchair
D. cap→computer→scalp→wheelchair
B. prove the technology useful to them
C. make them live longer
D. learn about their physical condition
B. New Findings About How the Human Brain Works
C. BCI Could Mean More Freedom for the Disabled
D. Robotic Vehicles Could Help to Cure Brain Injuries
(NEW YORK) A French tourist highly praised for rescuing a two-year-old girl in Manhattan said he didn"t
think twice before diving into the freezing East River.
Tuesday"s Daily News said 29-year who left the spot quickly after the rescue last Saturday.
He lifted the little girl out of the water after she fell off the bank at the South Street Seaport museum. He
handed the girl to her father, David Anderson, who had dive in after him.
"I didn"t think at all," Duret told the Daily News. "It happened very fast. I reacted very fast."
Duret, an engineer on vacation,was walking with his girlfriend along the pier (码头) when he saw something
falling into the water.He thought it was a doll, but realized it was a child when he approached the river. In an
instant,he took off his coat and jumped into the water.
When he reached the girl, she appeared lifeless, he said. Fortunately, when she was out of the water, she
opened her eyes.
Anderson said his daughter slipped off the bank when he was adjusting his camera. An ambulance came
later for her, said Duret, who was handed dry clothes from cookers. Duret caught a train with his girlfriend
shortly after.

The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots
he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters
or other emergencies.
Dan Kara is president of Robotics Trends, a Northboro, Mass.-based company that publishes an
online industry magazine and runs robotics trade shows. He said there are other snake-like robots being
developed, mainly at universities, but didn"t know of one that could climb pipes.
The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be
controlled with a joystick (操纵杆). They move smoothly with the help of small electric motors, or servos,
commonly used by hobbyists in model airplanes.
Built from lightweight materials, the robots are about the size of a human arm or smaller. They can
sense which way is up, but are only as good as their human operators, Choset added.
Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana,
said snake-type robots would offer greater mobility than equipment currently available, such as cameras
attached to extendable roles.
"It just allows us to do something we"ve not been able to do before," Stover said,"We needed them
yesterday."
He said sniffer dogs are still the best search tool for rescue workers, but that they can only be used
effectively when workers have access to damaged building.
Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake
robots would have helped rescuers search flooded houses in that disaster.
Choset said the robots may not be ready for use for another five to ten years, depending on funding.
B. Pittsburgh City Council.
C. Carnegie Mellon University.
D. Federal Emergency Management Agency.
B. can be used by hobbyists in model airplanes
C. can find victims more quickly than a sniffer dog
D. can sense its way no better than its operators
B. would have been put to use in past rescue work
C. helped rescuers search flooded houses yesterday
D. were in greater need yesterday than today
B. Snake-like robots made to aid in rescues.
C. The development of snake-like robots.
D. The working principles of snake-like robots.
(道德的) standards throughout her youth. In 1984, at the age of 23, she married Bill. They were
blessed with two children, a boy and a girl.
By 1991 their love had deepened, and they were happy. Later that year, Bill developed a white
spot on his tongue. He visited a doctor.
One day shortly after that, Bill called Karen to sit beside him. He said with tears in his eyes that he
loved her and wanted to live forever with her. The doctor suspected that he had been infected with HIV,
the virus that leads to AIDS.
The family was tested, Bill and Karen"s results were positive. Bill had become infected before he met
Karen then he passed the virus on to Karen. The children"s results were negative. Within three years. Bill
was dead, "I don"t know how to express what it is like to watch the once handsome man you love and
intend to live with forever dying slowly. I cried many nights. He died three months short of ten years of
our marriage," says Karen. Though a doctor told Karen that she would soon follow her husband into death,
she is still alive. The infection has progressed to the early stages of AIDS.
Karen is hut one of about 30 million people now living with HIV/AIDS, a figure larger than the
combined populations of Australia. Ireland and Paraguay. According to one UN report, Africa has 21 million
of these victims. By the turn of the century that number could reach 40 million and the disease will bring
on the greatest disaster in human history. Of the world"s sexually active adults aged 15 to 49. 1 in 100 has
already been infected with HIV. Of these, only 1 in 10 realizes that he or she is infected. In some parts of
Africa, 25 percent of the adults are infected.
Since the beginning of the spread of AIDS in1981, about 11.7 million people have died of it. It is
roughly calculated that in 1997 alone, about 2.3 million people died of it. Nevertheless, there are fresh
reasons for optimism in the battle against AIDS. During the past few years, there has been a drop in new
AIDS cases in wealthy nations. In addition, promising drugs hold out hope of better health and longer life.
B. stress the importance of medical tests
C. express sympathy for AIDS victims
D. show the consequences of AIDS
B. were asked to adopt
C. regretted having
D. gave birth to
B. the family members were tested
C. Karen persuaded him to see the doctor
D. he found something wrong with his tongue
B. the spread of AIDS could be controlled
C. it is hopeless to win the battle against AIDS
D. the death rate of AIDS patients has been reduced
