NASA on September 28, 2015 announced the strongest evidence yet for liquid water on the red planet, increasing the possibility that astronauts journeying to Mars could someday rely on the planet's own water for their drinking needs.
You may feel like you've heard about the hunt for liquid water on Mars before—and the researchers involved know it may seem played out. But science has yet to truly prove that water flows on Mars once and for all, and doing so could completely change the way we view the planet. This new data is a big step in the right direction.
"Liquid water is an attractive topic, and we like the thousandth time someone has discovered water on Mars," Lujendra Ojha, the Georgia Tech PhD candidate who led the research announced Monday, told The Post. But there's a good reason that liquid water is so "attractive": Mars is now the only planet in our solar system to show evidence of the stuff on its surface, other than our own. Other worlds have it in subsurface oceans, or scattered around as vapor in the atmosphere. But Mars is the only place where we have solid evidence for liquid that sits right there in the open air. While it would be a major leap to suggest that Mars might harbor life—even microbial life—liquid water at least makes it possible that parts of the planet are habitable.
The study builds on research from April, when scientists using data from the Curiosity rover noted that the planet had the seasonal potential for liquid water. We know that because of the extremely low pressure on Mars, water has a boiling point of just a few degrees Celsius, after which it evaporates. The April study noted the presence of perchlorates (高氯酸盐) —a kind of salt—which could make the boiling point of Mars' water much higher, theoretically allowing it to remain liquid. They affirmed that the planet's temperature would be right for liquid, perchlorate-filled water to form every day during winter and spring.

In a touching story, a family was shocked to find that a stranger had secretly paid for more than half of their Christmas gifts.
When Ayers went to make a payment toward the $283 balance for her family’s Christmas gifts at Walmart, her money was refused. According to a Walmart employee, a woman had paid a part of Ayers’ bill after seeing her shopping in the store. The unknown woman also left Ayers a touching note, which left the mother of two in tears.
Ayers, whose sons are 11 and 3, says the stranger’s great generosity came at the perfect time for her family. Before the anonymous payment was made, Ayers had worried she would not be able to get her kids’ toys in time for Christmas.
Ayers is still looking for the woman who helped pay for their Christmas gifts for her kids. She took a picture of her receipt with the headline: This stranger paid 4 gifts for us. I wish I could thank her for helping give our kids a Merry Christmas!
For thousands of families like Ayers’, feeling this financial pressure around Christmastime is nothing new. These families who still have a roof over their heads and food on their tables often slip through the cracks — they can afford all the necessities, but the “extras” are harder to come by. Considering that Americans are estimated to spend $882 on Christmas gifts this year, it makes sense that a family with a few financial problems would have a hard time filling the stockings for their kids.
Realizing how common this Christmas problem really is makes Ayers’ story even more special. These random acts of kindness around the holidays, often from nameless strangers, can determine what a family’s Christmas looks like. Christmas may not be all about the material stuff, but for families, and especially for kids, it’s the little things that can make the biggest difference.
1.Why did the Walmart employee refuse Ayers’ money?
A. She was too poor to afford it.
B. Her money was not enough.
C. Someone had paid for her.
D. The charismas gifts were free.
2.Why is Ayers still looking for the nameless woman?
A. To say thanks to her.
B. To pay her money back.
C. To praise her online.
D. To make friends with her.
3. Which of the following best describes families like Ayers’?
A. They value Christmas very much.
B. They try their best to buy kids gifts.
C. They hate to spend Christmas.
D. They live from hand to mouth.
4.What’s the author’s attitude towards the acts of kindness?
A. Praiseful. B. Helpful.
C. Troublesome. D. Useless.

On a later summer evening, my father and I was walking happily home. We have just had a big meal in a restaurant near our home. As we were walking slowly down the street, I asked my father in a low voice, "What does the word 'drunk' mean?" "That's easily, boy," said my father. "Do you see these two policemen over there? If I look at them, I see four instead two, and I'm drunk. Understand?" Hearing at this, I pretended to be puzzled, and said, "My God, and there are six policemen over there. Can't you see?" My father looked at me in great surprised. "You are really drink, son."
