Open your hand or hold your fingers out straight as you saw I doing, and then pull.” To his surprise, the child says, “I can’t hold my fingers straight like that, because I don’t want to drop my penny.” Thousand of us sometimes are so busy hold on to the world’s worthless penny that we cannot achieve liberation.

“Mum, what does it mean when someone tells you that they have a skeleton（骨骼）in the closet（衣橱）?” Jessica asked. “A skeleton in the closet?” her mother paused thoughtfully. “Well, it’s something that you would rather not have anyone else know about. For example, if in the past, someone in Dad’s family had been arrested for stealing a horse, it would be ‘a skeleton in his family’s closet’. He really wouldn’t want any neighbor to know about it.”
“Why pick on my family?” Jessica’s father said with anger. “Your family history isn’t so good, you know. Wasn’t your great-great-grandfather a prisoner who was transported to Australia for his crimes?” “Yes, but people these days say that you are not a real Australian unless your ancestors arrived as prisoners.” “Gosh, sorry I asked. I think I understand now,” Jessica cut in before things grew worse.
After dinner, the house was very quiet. Jessica’s parents were still quite angry with each other. Her mother was ironing clothes and every now and then she glared at her husband, who hid behind his newspaper pretending to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica’s closet. Just as she opened the door and reached in to hang a skirt, a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor. Jessica’s mother sank in a faint（晕倒）, waking only when Jessica put a cold, wet cloth on her forehead. She looked up to see the worried faces of her husband and daughter.
“What happened? Where am I?” she asked. “You just destroyed the school’s skeleton, Mum,” explained Jessica. “I brought it home to help me with my health project. I meant to tell you, but it seemed that as soon as I mentioned skeletons and closets, it caused a problem between you and Dad.” Jessica looked in amazement as her parents began to laugh madly. “They’re both crazy,” she thought.

The world is not coming to an end on December 21st, 2012, the US space agency announced to dispel （消除）widespread rumors fueled by the Internet and a new Hollywood movie．
The latest big screen 2012 was based on stories according to the Mayan calendar．It showed that by the end of 2012, a Planet X will collide （碰撞） with the earth．
Some websites accuse NASA of hiding the truth on the planet's existence, but the US space agency considered such stories as tricks．"There is no basis in fact for these claims," NASA said in its website．"If such a collision were real, scientists would have been tracking it for at least the last decade, and we would see it with our eyes now．Obviously, it doesn't exist and there will be no threat to the earth in 2012," it insisted．"After all, our planet has been getting along just well for more than four billion years," added NASA．
There is another planet, Eris, floating in space．But the small planet will remain safely fixed in the outer solar system and it can come no closer than four billion miles to the earth, according to NASA．
And even if the planets were to line up as some have forecast, the effect on our plant would be very little．"And while comets and asteroids （小行星） have always hit the earth, big hits are very rare," NASA noted．The last major collision was believed to be 65 million years ago, resulting the end of dinosaurs （恐龙）．
"We are sure that there are no threatening asteroids as large as the one that killed the dinosaurs," the space agency said．
1.What played a key role in the spread of the rumors?
A．The Internet and the film 2012． B．The Mayan calendar．
C．The US space agency． D．The television screen．
2.The underlined word "it" in Paragraph 3 probably refers to _________.
A．the collision B．the threat C．the Planet X D．the NASA website
3.We can conclude from the passage that __________.
A．the film 2012 is well accepted in the science field
B．scientists have been tracking Planet X for over ten years
C．the earth will exist for more than four billion years
D．the rumors caused a panic among some people
4.What do we know about Eris according to the passage?
A．It doesn't exist in the universe．
B．It won't threaten the earth．
C．It is too far to be seen．
D．It is similar to the earth.
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, 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（消极的） impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic."
1.What can be the best title of the passage?
A．Sea Life Facing Danger
B．Scientist Researching Seawater
C．Oceans Becoming More Acidic
D．Climate Change Affecting Seawater
2.With the increase of atmospheric CO2， .
A．more corals will appear in the sea
B．the surface water is becoming warmer

3.Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a．Sea life is endangered．
b．CO2 goes into the surface water．
c．The ocean chemistry is affected．
d．CO2decreases the PH and makes the seawater more acidic．
e．CO2 levels in the atmosphere go up．
4.Scientist Robert Dore came to the conclusion based on .
A．his research and analysis
B．the expectation of other scientists
C．some former theory
D．a major cause of climate change
