At least 12 other murders since 1997 have been linked to an addiction to violent video games. This year, the parents of a 14-year-old murder victim in the UK blamed the killer’s addiction to the game Manhunt, causing a government review of legislation（立法）to protect children.
But is there any scientific evidence that mere games can make children and young adults more aggressive, or possibly have the desire to murder？ There is no doubt children are being exposed to more games violence than ever: around a quarter of all games released in the US contain some violence. And the violence is becoming more obvious as increases in computing power make the games look ever more realistic.
Psychologists think there may be many reasons why violent games are more harmful to children than violent movies. Firstly, players are actively involved in violence, and may begin to use weapons as second nature. Secondly, violent games provide repetitive aggressive experiences that are rewarded by more killing.
Many studies have shown that people who play violent games regularly are more likely to show high levels of aggression. For instance, in 2000, Craig Anderson of Iowa State University in Ames and his colleague Karen Dill found that people who played violent games were more likely to admit to aggressive behaviour, including attacks or robberies.
Earlier this year, Krahe and her colleague Ingrid Miller reported a study of 13 to 14-year-old children. More than half had played games recommended only for over-18s. The more violent the games they played, the more they considered physical aggression to be acceptable. Other authors in the same edition report that children who play violent games more likely to argue with teachers and fight with others.
Experimental studies have also pointed out a possible link. In one, Anderson and Dill asked a group of students to play a violent game, Wolfenstein 3D, while another group played the non-violent Myst. Those who played the violent game were faster to react to aggressive words flashed on screen and appeared more aggressive.
The issue is controversial, however. Jeffrey Goldstein, a psychologist at the University of Utrecht in the Netherlands and a consultant to some video games publishers, agrees that there is good evidence that children, who are exposed to violent media, including video games, are more aggressive. But he warns it might not be a simple case of cause and effect: aggressive kids might be most attracted to violent games.
1.What will be probably discussed in the paragraph following the passage?
A. Further research on the harm of violent games.
B. The results of more experimental studies.
C. Ways to protect children from violent games.
D. Further research on the advantage of violent games.
2.Violent games are more harmful to children than violent movies because ________.
A. violent movies are not so attractive to children
B. the viewers can’t take part in violent movies
C. violent movies are not popular with children
D. children can win awards in violent games
3.What can be inferred from the passage?
A. There are at least 12 murders in 1997 linking with violent games.
B. Children who play computer games often quarrel with their teachers and parents.

Since the 1970s, scientists have been searching for ways to link the brain with computers.Braincomputer interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan 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 hand. 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. Millan, 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.
1.How did Tavella operate the wheelchair in the laboratory?
A．By controlling his muscles.
B．By talking to the machine.
C．By moving his hand.
D．By using his mind.
2.Which of the following shows the path of the signals described in Paragraph 5?
A．scalp→computer→cap→wheelchair
B．computer→cap→scalp→wheelchair
C．scalp→cap→computer→wheelchair
D．cap→computer→scalp→wheelchair
3.The team will test with real patients to________.
A．make profits from them
B．prove the technology useful to them
C．make them live longer
D．learn about their physical condition
4.Which of the following would be the best title for the text?
A．Switzerland, the BCI Research Center
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

高三英语单项填空简单题查看答案及解析
People have been told to stay separated — at least six feet apart— and to practice what state and local officials call “social distancing”. Some have been asked to work at home. But as people try to slow the spread of the novel coronavirus（ 新型冠状病毒）, the resulting chaos and fear are bringing both large and small communities closer.
Simple acts of kindness are sprouting up online and in public, as neighbors, students, teachers, and others begin to connect those who can pass this long and isolating time smoothly, and the people who may not have the means to get through.
For Jesse Farren-James, helping out has taken the form of organizing trips to the
supermarkets for supplies, and use of her membership card if anyone needs to buy large quantities. She posted the offer in a Facebook group for the community residents, and some people came and turned to her. “I just feel so lucky that I have so many people in my life to rely on and so sad that not everyone has that,” she wrote in the group. In another interview, Farren-James said the “community is coming together" and “there are so many good and amazing people” offering to help where they can.
Also, parents in Dorchester have gathered together online. In a Facebook group called DotParents, parents have been raising money to buy food and supplies for students and families in the community. Lisa Graustein has been organizing this activity. On Thursday, she used the more than $2,000 raised by neighbors to purchase food in a restaurant supply company. A group of volunteers packed the food and planned to distribute to schools for those who may need it.
“Food shortage is real in our city and this crisis is going to be severe.” Graustein said. “But here's something we can do that deal better with the hard time”. This idea is spreading. She said friends in four other states had being running similar campaigns. Next, she wants to find a way to get landlords to temporarily abandon rent for residents in financial difficulties because of the outbreak.
1.The underlined phrase in paragraph 2 “sprouting up” can be best replaced by .
A.Disappearing B.Growing
C.Connecting D.Helping
2.What do we know about Jesse Farren-James?
A.She is a shopping assistant working for a supermarket.
B.She is wealthy and always ready to help others.
C.She lent her membership card to the people in need.
D.She felt sad that not everyone has enough food.
3.What did parents in Dorchester do to offer help?
A.They bought food from the supermarket for community children.
B.They set up a restaurant supply company to provide food.
C.They raised money to deal with food shortage.
D.They distributed money to community residents.
4.Which is the best title for this passage?
A.Acts of kindness in coronavirus outbreak
B.Effects of social media in coronavirus outbreak
C.Social distancing in the online community
D.Helping each other in financial difficulties
