Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
“We’ve been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we’ve been able to record this increasing quantity of atmospheric CO2 into the ocean.”
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
“As carbon dioxide dissolves (溶解) in the water, or seawater in this case, it forms a weak acid (酸), carbonic acid, ” Dore explains. “And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic.”
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
“It’s important to realize that the oceans are really becoming acidic。And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic.”

More teachers are starting off the school year with letters to parents and students to introduce themselves and set a tone (基调) for the year. The letters are a good way to start positive communication with parents, several teachers told Education World.
“I think it’s professional, ”said Dorothy Peselli, an English teacher at Sparta High School in Sparta, New Jersay, Peselli, who gives out the letters the first day of school, told Education World. “It gives parents an image of you as a professional. If you start communication off in a positive manner, you will have the parents on your side when you need them.”
In her letter to parents, Peselli encourages them to call or e-mail her with specific concerns about their children. “I want to work as a team to make sure that your child becomes an independent lifelong learner,” Peselli wrote to parents last September. She also telephones the parents of all her students at the beginning of the year.
Peselli includes with the letter a classroom handbook (手册) listing plans and rules. And she requires that both parents and students read and sign statements (included in the letter) when they read the handbook. The student letter also lists needed supplies and gives encouragement. “Please come to class ready to work and learn. This will be an exciting year for all of us,” it says.
Last year, Peselli taught at a different high school and parents there were “shocked”, but appreciative, that she had so much contact with them. “I received roses and a thank-you note from one boy and his mother,” Peselli said. She wished her own children’s teachers would take the time to write notes as well. “I never got a letter home from any of my daughter’s high school teachers.” she said, “It would be nice to know the background of some of the people who are teaching my daughter.”

第三部分：阅读理解（共20小题，每题2分，满分40分）
There was room for all of us, and the sleeping bags kept the night coldness away. We would listen to the sound of the river, and hear the coyotes (土狼) howling along the hills not far away.
Those were the cool summer nights of the mid-nineties in Southern Alberta, Canada, when the four children were young and we would lie on the trampoline (蹦床) in the backyard late at night, for the sun would not set till late in July and August. We would look at the stars up above and never grow tired of it.
These were the times when I would tell the stories of my own childhood and teach the kids life’s lessons that have been remembered to this day. I chuckle (轻声地笑), as I recall the time when we heard a coyote not far away, and then I started a story about a bear approaching the trampoline. The bear came close (in the story), and the kids snuggled up to mom and me, until suddenly I’d let out a howl and grab all the kids and they would be frightened and jump up and then all laugh, “Daddy, you scared us!”
Now the children are in their mid and late teens, but they fondly remember the starry nights on that trampoline. Recently my oldest daughter on her wedding day sang a song for her parents, entitled “I’ll always be your little girl”. She wrote the music and words and yes indeed: it included a memory of those starry nights.
I have learned as a parent that one of the greatest gifts we can give our children as they are growing up is the time to tell them stories, or if telling stories is not that simple, perhaps read them a story. They can read their own books, but telling or reading them a story will create a close relationship with pleasant memories such as those late summer nights under the starry sky.
1. The passage is mainly about _____.
A. coyotes’ effects on children B. the relationship between children
C.the author’s unforgettable experiences D. the author’s memories of starry nights
2. The underlined part “snuggled up” probably means _____.
A. lay down B. got close
C.gave in D. struggled forward
3. How do the children feel about their childhood?
A. Very enjoyable.B. A bit regretful.
C.Rather busy. D. Sort of dull.
4. In the last paragraph, the writer mainly wants to express _____.
A. it is easy to tell stories to children B. kids should read stories themselves
C.it is important to tell or read stories to kids
D. it’s necessary to spend summer nights with kids

Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter, Maureen. With a checklist of criteria in hand, the Dallas family looked around the country visiting half a dozen schools. They sought a university that offered the teenager’s intended major, one located near a large city, and a campus where their daughter would be safe.
“The safety issue is a big one,” says Joe Mahoney, who quickly discovered he wasn’t alone in his worries. On campus tours other parents voiced similar concerns, and the same question was always asked: what about crime? But when college officials always gave the same answer — “That’s not a problem here.” — Mahoney began to feel uneasy.
“No crime whatsoever?” comments Mahoney today. “I just don’t buy it.” Nor should he: in 1999 the U.S. Department of Education had reports of nearly 400,000 serious crimes on or around our campuses. “Parents need to understand that times have changed since they went to colleges,” says David Nichols, author of Creating a Safe Campus. “Campus crime mirrors the rest of the nation.”
But getting accurate information isn’t easy. Colleges must report crime statistics （统计数字) by law, but some hold back for fear of bad publicity, leaving the honest ones looking dangerous. “The truth may not always be obvious,” warns S. Daniel Carter of Security on Campus, Inc., the nation’s leading campus safety watchdog group.
To help concerned parents, Carter promised to visit campuses and talk to experts around the country to find out major crime issues and effective solutions.

2.It is often difficult to get correct information on campus crime because some colleges ______.
A. receive too many visitors B. mirror the rest of the nation
C. hide the truth of campus crime D. have too many watchdog groups

A. mind B. admit C. believe D. expect
4.We learn from the text that “the honest ones” in the fourth paragraph most probably refers to colleges ______.
A. that are protected by campus security B. that report campus crimes by law
C. that are free from campus crime D. the enjoy very good publicity

A. Exact campus crime statistics. B. Crimes on or around campuses.
