The Science of Risk-Seeking
Sometimes We decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth tasking. 1.Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.
The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring.2.As the quality of Risk-taking was passed from on ration to the next, humans ended up with a sense of adventure and a tolerance for risk.
So why aren’t we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. 3.
No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. 4.To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.
5.,for the risk-seekers a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.
As experts continue to study the science of risk-seeking, we’ll continue to hit the mountains, the waves or the shallow end of the pool.
A. It all depends on your character.
B. Those are the risks you should jump to take.
C. Being better at those things meant a greater chance of survival.
D. Thus, these well-equipped people survived because they were the fittest.
E. This is when you start to move away from your family and into the bigger world.
F. However, we are not all using the same reference standard to weigh risks and rewards.
G. New brain research suggests our brains work differently when we face a nervous situation.
Since the 1970s, 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 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.BCI is a technology that can ________.
A. help to update computer systems
B. link the human brain with computers
C. help the disabled to recover
D. 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 moving his hand.
D. By using his mind.
3.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
More students than ever before are taking a gap year(间隔年) before going to university. It used to be the “year off” between school and university. The gap-year phenomenon originated(起源) with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year.
This year, 25,310 students who have accepted places in higher education institutions have put off their entry until next year, according to statistics on university entrance provided by the University and College Admissions Service (UCAS).
That is a record 14.7% increase in the number of students taking a gap year. Tony Higgins from UCAS said that the statistics are good news for everyone in higher education. “Students who take a well-planned year out are more likely to be satisfied with, and complete, their chosen course. Students who take a gap year are often more mature and responsible,” he said.
But not everyone is happy. Owain James, the president of the National Union of Students (NUS), argued that the increase is evidence of student hardship – young people are being forced into earning money before finishing their education. “New students are now aware that they are likely to leave university up to￡15,000 in debt. It is not surprising that more and more students are taking a gap year to earn money to support their study for the degree. NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacating periods,” he said.
1.What do we learn about the gap year from the text?
A. It is flexible in length.
B. It is a time for relaxation
C. It is increasingly popular
D. It is required by universities
2.According to Tony Higgins, students taking a gap year ____.
A. are better prepared for college studies
B. know a lot more about their future job
C. are more likely to leave university in debt
D. have a better chance to enter top universities
3.How does Owain James feel about the gap-year phenomenon?
A. He’s puzzled B. He’s worried
C. He’s surprised D. He’s annoyed
4.What would most students do on their vacation according to NUS statistics?
A. Attend additional courses.
B. Make plans for the new term
C. Earn money for their education
D. Prepare for their graduate studies
