Since NASA's Viking Task tested Martian soil back in the 1970s，we've known that Mars （火星） is covered with a desert—harmful to life as we know it.But since tasks to Mars paid attention to what lies under the desert，a different picture has started to appear.
This discovery of water under the Mars' South Pole is the result of radar echoes （雷达回波） that were picked up by an instrument on a spaceship that's been moving around Mars for 15 years.To stay liquid （液体） under the long﹣frozen desert of Mars，the researchers say this lake must have a lot of salts mixed in it.
It is very cold and saltiness would make it a very hard environment for any living thing.But the lead researcher，Professor Roberto Orosei from the Italian National Institute for Astrophysics，said it was not impossible for things to live there.
To search for life in this newly discovered lake，scientists will need to send a robot that's able to make a hole through the mile of ice covering it.But at least the teams looking for life on Mars will now know where to start their search.

All around the world, people drink tea. But tea does not mean the same thing to everyone. In different countries people have very different ideas about drinking tea.
In China, for example, tea is always served when people get together. The Chinese drink it at any time of the day at homes or in teahouses. They like their tea with nothing else in it.
Tea is also important in Japan. The Japanese have a special way of serving tea called a tea ceremony(仪式). It is very old and full of meaning. There is even a special room for it in Japanese homes.
Another tea drinking country is England. In England, the late afternoon is teatime. Almost everyone has a cup of tea. The English usually make tea in a teapot and drink it with milk and sugar. They also eat cakes, cookies and little sandwiches at teatime.
In the United States people often drink tea for breakfast or after meals. Americans usually use tea bags to make their tea. In summer, many Americans drink cold tea—“iced tea”. Sometimes they drink iced tea from cans, like soda(梳打).How many countries are there in the text to drink tea?

Napping(小睡) after learning something new could help improve your memory--- as long as you dream, scientists say.
They found people who dream about a new task do it better on waking than those who do not sleep or do not dream.
Volunteers were asked to learn the layout(布局，设计) of a 3D computer maze(迷宫) so they could find their way several hours later. Those allowed to take a pap and who also remembered dreaming of the task, found their way to a landmark quicker.
The researchers think the dreams are a sign that unconscious(无意识的) parts of the brain are working hard to process information about the task..
Dr. Robert Stickgold of Harvard Medical School, said dreams may be a marker that the brain is working on the same problem at many levels.
Study tips
Co-author Dr. Erin Wamsley said the study suggests our non-conscious brain works on the things that it deem(认为) are the most important.
“Every day we are gathering lots of information and new experiences,” she said. “It would seem that our dreams are asking the question, “How do I use this information to inform(影响) my life?”
The scientists say there may be ways to use this phenomenon(现象) for improving learning and memory. For example, students might be better studying hard before bedtime, or taking a nap after a period of afternoon study. Scientists say ______ could help improve your memory.
| A．dream | B．nap | C．nap and dream | D．nap without dream |
What were volunteers asked to do?
| A．Take a nap. | B．Dream a task. | C．Learn about 3D computer. | D．Find their way out of a maze. |
Which is right about dreams?

| B．They can help us fall asleep and improve learning and memory. |
| C．They tell us how to use this information to inform our life. |
| D．They may be a marker that the brain is working on the same problem. |
When is the best time for study?
| A．Before bedtime. | B．After bedtime. | C．Before taking a nap. | D．In the afternoon. |
I’ve loved my mother’s desk since I was just tall enough to see above the top of it as mother sat doing letters. Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be the most wonderful thing in the world.
Years later, during her final illness, mother kept different things for my sister and brother. “But the desk,” she’d said again, “it’s for Elizabeth.”
I never saw her angry, never saw her cry. I knew she loved me; she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter
They never happened. And a gulf opened between us. I was “too emotional(易动感情的)”. But she lived “on the surface”.
As years passed I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me.
I posted the letter and waited for her answer. None came.
My hope turned to disappointment, then little interest and, finally, peace—it seemed that nothing happened. I couldn’t be sure that the letter had even got to mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.
Now the present of her desk told, as she’d never been able to, that she was pleased that writing was my chosen work. I cleaned the desk carefully and found some papers inside--- a photo of my father and a one-page letter, folded(折叠) and refolded many times.
Give me an answer, my letter asks, in any way you choose. Mother, you always chose the act that speaks louder than words.The writer began to love her mother’s desk____________.
