Daily overuse of media and technology has a bad effect on the health of all children and teenagers by making them more open to anxiety, and more at risk of future health problems.1. Many newer apps automatically show where the users are when they’re used. This can tell anyone out there exactly where to find the person using the app.
2.They are also upset about their kids spending time on Facebook accounts instead of getting down to their homework assignments, and are afraid of what can come out of their online connections.
3. One way is to make a “social media agreement” with your kids—a real contract they can sign. In it, they can agree to protect their own privacy, consider their reputation, and not give out personal information.4.
In turn, parents agree to respect teens’ privacy while making an effort to be part of the social media world. Parents also can help kids spend less time on the computer by putting limits on media use.5.Avoid laptops and smartphones in bedrooms, and set some rules on the use of technology. And don’t forget that setting a good example through your own virtual behavior can go a long way toward helping your kids use social media safely.

B. Keep computers in public areas in the house.
C. It’s important to be aware of what your kids are doing online.
D. Besides, they promise never to use technology to hurt anyone else.
E. Spending too much time on social media can make kids feel upset, too.
F. Kids also can face the possibility of meeting the wrong person lace to face.
G. Parents often say that kids would rather be online than hang around with them.
Since 50 years ago, scientists have been searching for ways to link the brain with computers. Brain Computer Interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michelle 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.What is BCI?
A.BCI is a technology that can link the human brain with computers.
B.BCI is a technology that can help to update computer systems.
C.BCI is a technology that can help the disabled to recover.
D.BCI is a technology that can control a person's thoughts.
2.How did Tavella operate the wheelchair in the laboratory?
A.By controlling his muscles. B.By talking to the machine.
C.By using his mind. D.By moving his hand.
3.Which of the following shows the path of the signals described in Paragraph 5?
A.scalp→computer→cap→wheelchair
B.scalp→cap→computer→wheelchair
C.computer→cap→scalp→wheelchair
D.cap→computer→scalp→wheelchair
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

Buster used to be a lovely dog playing and running on a farm all day. His life had a big change after his handler Will’s presence because Will found he did extremely well in sniffing tests. Will thought Buster had a special talent and decided to let him become a member of RAF police working dogs. Buster began working with Will in 2007, and the pair was sent to Afghanistan’s deadly Helmand province. There, Buster saved countless lives by sniffing out explosive devices (IEDs), as well as weapons. He joined his comrades repeatedly on foot patrols hunting Taliban terrorists and tracking down bombs. He also acted as a useful diplomatic tool, due to his friendly approach to local children. The RAF soon had a long train of children in tow, as Buster drew in his crowd and entertained them.
After his glittering service with the RAF, Buster retired in 2011,and died in 2015 at the age of 13 at the home of his handler, Will, in Lincolnshire where he had been enjoying retirement with his handler Will, his wife Tracy and their two dogs who will inherit (继承) their father’s career.
Over the course of his career, Buster is thought to have saved more than 1,000 lives.

Captain Henry, a 98-year-old American retired fisherman, has become a first-time author, having written and published his autobiography In a Fisherman's Language after learning to read at the age of 91.
Mr.Henry spent most of his life without even his closest family members knowing he was illiterate. Forced to quit school in the third grade to take odd jobs, he kept the secret close to his chest, only telling his late wife. Henry's granddaughter, Marlisa, told reporters how he used tricks, like waiting for others to order at restaurants first, to avoid the issue.
A family argument in his 90s, she said, aroused his desire for education.“He signed a document he could not read about where he was going to live, Marlisa said. Starting with his name, he eventually moved on to the ABC's and children's books. He put them down since his wife fell ill. After the tragic loss of his wife, he went back to reading and began to log (记录) his life. He wrote about his family's voyage from Portugal to the US, how he went on to captain a boat, and his many journeys at sea.
His life stories have become so popular that nearly 800 copies were sold in the first two weeks after the book's release. One thousand more have since been printed as requests for the book flood in from as far as Germany. And now even Hollywood producers have approached Mr. Henry about buying the rights to his life story for a big screen adaptation.
The family also now has a book agent and a deal in the works to publish a second edition. Meanwhile, the family says they are reconnecting and closer than ever as a result of Henry's late-life efforts.“Everyone has a story,” Marlisa said, “It teaches that when you're down and out, never give up.”
