Clearing the air in class saw significant boosts to reading and math achievement of students, according to a New York University study, even though the outdoor pollution didn’t prove to be a problem. The findings suggest improving air quality may also help disadvantaged students who often live in more polluted areas and attend class in older buildings.
Michael Gilraine, study author at New York University, analyzed both the air quality and the math and reading test scores at the 18 schools. In schools that received the new air filters, students improved by 0.18 of a standard deviation(标准偏差) in reading and 0.2 of a standard deviation in math, compared to students’ performance in the schools that did not receive air filters. To put that in perspective, those gains are about equal to the learning benefits from reducing class sizes or providing intensive tutoring. Students sustained those math and reading gains the next year, particularly if they attended the same school or another that had installed new filters in the following year. “In fact, given the large test-score increases they generate, installing air filters actually outperforms other education reforms such as class-size reduction on a cost-benefit basis,” Gilraine said.
Prior studies have found that better air quality can lead to fewer teacher and student absences, particularly for those with chronic asthma (慢性哮喘) or other respiratory illnesses. While schools with the new air filters installed did have lower student absenteeism, attendance alone didn’t seem to be driving the gains in math and reading achievement. Rather, he said, “you can get a lot just from being able to think clearly while you take a test. And then you also might be learning a bit better because you’re thinking clearer in class from day to day”.
Separate studies have found rising average temperatures likewise can increase indoor air pollution and reduce student achievement, particularly if students take tests on hot days.
“We’ve had a decade or more of research into the effects of lead. There’s been much less research on the effects of air quality We’re still in early days.” added Gilraine.
1.What did the study find?
A.Outdoor pollution does harm to students’ health.
B.Clean air promotes the students’ study achievement.
C.Air quality puts New York University at a disadvantage.
D.Polluted areas and old buildings have air problems.
2.How did the researcher conduct his study?
A.By making analysis and comparison.
B.By giving examples and listing basic data.
C.By telling stories and doing experiments.
D.By demonstrating the causes and effects.
3.According to Gilraine, what makes the students gain achievement?
A.Fewer teacher and student absences.
B.Rising temperatures in class.
C.Clearer thinking in better air quality.
D.Taking a math and reading test everyday.
4.What can we infer about the Gilraine’s research?
A.It will focus on the research of lead. B.It gets off with a good start.
C.It gets lots of support from schools. D.It still has a long way to go.

"There's Always a John" By Darla Boyd
My first year of teaching, there was a kid named John in my class. John was difficult to control and he nearly drove me crazy. While talking about him one day, an old teacher put his hand on my shoulder and said, "There will always be a John. Your job is to learn to discover what makes him different and help him succeed." The next year, there was indeed another John. But that advice taught me that there is something to appreciate in everyone.
"An Early Key Lesson" By Elaine West
Before I began my first teaching job, my mother, a teacher of 30 years, gave me a very special gift, five simple words that have had an effect on my entire life." Make friends with the janitor（门卫）." Her wisdom taught me the respect for all types of characters and continues to enrich my life to this day. Just five little words but what an impact they can have when you take them to heart.

Sarah came running in saying, "Look what l found. " Over the top of the paper I was reading I saw a long object that made me jump. It was a piece of snakeskin that had been shed （脱皮) by one of our garden snakes.
'Isn't it beautiful?" said my wide-eyed 7~year-old daughter. I stared at the organic wrapper and thought to myself that it really was not that beautiful, but I did not want to disappoint Sarah. Everything children see for the first time is elementary to their sense of beauty and creativity. They see only merit (忧点) and excellence in the world.
"Why does it do this?" Sarah asked. I like to teach my children that there is something else going on besides what they see in front of them. "Snakes shed their skin because they need to renew themselves," I explained.
"Why do they need to renew themselves?" Sarah asked. "We often need to shed our skins, those coatings that we cover ourselves with," I said to my now absorbed daughter. "We outgrow some things and find other stuff unnecessary. This snake no longer needs this skin. It is probably too old, and the snake probably doesn't think it looks as smart in the skin as it once did. Like buying a new suit. "
Of course, I'm sure this explanation won't suit naturalists. But Sarah got the point. As we talked, I knew that she began to understand that renewal is part of progress; that we need to take a good look at ourselves, and rooms and schoolwork and creativity, and she began to see what we need to keep and what need to cast off. I was careful to point out that this is a natural process, not one to be forced.
"Snakes don't peel off their skin when they feel like it," I explained. "lt happens as part of their growth. "
"I see, Dad. " said Sarah. She then jumped off my lap, grabbed the snakeskin, and ran off.
I hoped she would remember this. Often, in order to find our real selves underneath the layers of community and culture we are cloaked (掩饰) in year after year, we need to start examining these layers. We need to gently peel some away, as we recognize them to be worthless, unnecessary, or flawed (有缺陷的); or at best, remember the things we discard（丢掉）to teach us how we can improve.
1.When Sarah asked the author whether the snakeskin was beautiful,___________
A．he was shocked and jumped
B．he tried to understand her point of view
C．he thought that telling the truth was a merit
D．he decided to teach her something about the garden
2.How did Sarah feel about the author's explanation?
A．Confused. B．Boreci C．Satisfied. D．Excited.
3.Which of the following would the author agree with?
A．By reflecting on ourselves, we can better ourselves.
B．It is necessary to force others to remove some things.
C．The community and culture force us to change.
D．It is natural to keep some old clothes.
4.From the text, we can conclude that the author___________.
A．does not like nature much
B．takes the chilcl's feelings lightly
C．is both a logical and thoughtful person
D．loves to see his daughter excited about animals
5.Which of the following could be the best title for the article?
A．The things we should cast off B．A shed snakeskin in Sarah's eyes
C．A natural part of our growth D．Renewal for snakes and us
