Does solving a math problem give you a headache? Do you feel nervous when you sit a math exam? For most students, math can be tough but scientists have proved that math problems can actually trigger physical pain.
Scientists came to his conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fear math. Those involved were asked a series of questions such as how they feel when they receive a math textbook or when they walk into a math lesson.
Based on their answers, participants were divided into groups. One group was made up of people who were particularly afraid of math and participants in the other group were more comfortable with the subject.
Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue square would be shown.
Using a brain-scan machine, scientists noticed that whenever people from Group One saw a yellow circle, their brain would respond in a way similar to when their body is feeling pain. It was like the pain they would fee, for example, if they burnt their hand on a hot stove. But they reacted less strongly when they knew that they would be faced with a word task.
However, scientists saw no strong brain response from people in the second group.
Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. “When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong,” explained Ian Lyons from University of Chicago, US, leader of the study. “The higher a person’s anxiety of a maths task, the more he activated brain regions associated with threat detection, and the experience of pain.”
More interestingly, the brain activity disappeared when participants actually started dealing with the math tasks. “This means that it’s not that math itself hurts; rather, the anticipation of math is painful,” Lyons said.
Based on the study, scientists suggested that things could be done to help students worry less and move past their fear of math, which might mean they perform better in tests.
63. In the first stage, scientists ask participants some questions to _.
A. see whether math hurts B. find out how much they fear math
C. observe how their brain response D. test their endurance of pain
64. The underlined word “the anicipation of math” is closest in meaning to .
A. the attempt of learning math B. the motivation to work out math problem
C. the effort to understand math D. the act of thinking about math
65. Which is the best title for the passage?
A. How to overcome math fear. B. Physical pain affects math performance.
C. Math pain in your brain. D. Unknown truth about pain.
66. What can be concluded from the experiment?
A. The anticipation of math has no relation to students’ confidence in math.
B. Moderate mathematic anxiety promotes students’ academic performance.
C. Effective solutions have been worked out to lower students’ anxiety of math.
D. Physical pain caused by HMA disappears in the process of doing math problem.

Many people believe the glare from snow causes snowblindness. Yet, dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness, when exposed to several hours of “snow light”. The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country. A man's eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain(地域). So his long look continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and eyeballs become sore and the eye muscles ache. Nature offers this discomfort by producing more and more liquid which covers the eyeball. The liquid covers the eyeball in increasing quantity until vision became not clear, and then is not easily seen and the result is total, even though not very long, snowblindness.
Experiments led the Army to a simple method of solving this problem. Scouts, ahead of a main body of troops, are trained to shake snow from evergreen bushes creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their eyes focus on a bush and have something to see. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white terrain is solved.
1. The first paragraph is mainly concerned with ________.
A. need for dark glasses
B the whiteness from snow
C. headaches, watering eyes and snowblindness
D. snow glare and snowblindness
2. According to the author, recent work on snowblindness shows that it is caused by ________.
A. exposure to bright light
B. failure to focus on an object
C. a loss of vision which doesn't last long
D. focusing on dark colored objects for a very long time
3. Suppose you walk across a completely snow-covered area, what should you do to solve the problem of snowblindness?
A. By wearing dark sun glasses.
B. By throwing an extra pair of black shoes ahead.
C. By asking the Army for help.
D. By walking backwards.
4. A suitable title for this passage would be ________.
A. Snowblindness and How to avoid it B. Soldiers in Snow
C. Nature's Cure for Snowblindness D. Snow Vision

Called “the School of the Future” and created with help from software giant Microsoft, a recently-opened public school in Philadelphia, US, is believed to be the first in the world to combine innovation teaching methods with the latest technology. At this school, students work on wireless laptops, teachers avoid traditional subjects for real-world topics and parents can track their child's work on the Internet.
The school, which cost the school district $63 million to build, is free and has no entrance exams. The 170 ninth-grade students were selected at random from l,500 applicants.
Philadelphia School District Chief Executive Paul Vallas told students they would be observed by other schools around the world. “You have become instant role models,” Vallas said. “People are going to be watching you. “
Students still sit in classrooms, but lessons rely heavily on information found on the Internet and on interactive software. Students will be allowed to learn at their own pace. Homework is done on computer and sent to the teacher for grading and parents can access the school's network to read teacher feedback on their child's progress.
Traditional education fails to teach students the skills of problem-solving, critical thinking and effective communication, which they need to succeed in the 21st century, Principal Shirley Grover said in an interview. “It's not about memorizing certain algebraic equations (代数方程式)and then presenting them in a test,” Grover said. “It's about thinking how maths might be used to solve a quality-of-water problem or how it might be used to determine whether or not we are safe in Philadelphia from the birdflu.”
David Terry, 14, said he was hoping to “turn over a new leaf” after discipline problems in his previous school left him with an “average to really bad” academic record. “This is a great opportunity for me,” he said. “In other schools, I would not .”
