Scientists have found living organisms trapped in crystals(晶體) that could be 50,000 years old.
The organisms were found in a hot, but beautiful cave system in Naica, Mexico. These ancient life forms can be seen only with a microscope. Penelope Boston, who leads the Astrobiology Institute at NASA, the space agency of the United States, says the ancient microbes(微生物) were able to live by eating minerals such as iron.
She spoke about the discovery recently at a meeting of the American Association for the Advancement of Science. If the findings are confirmed, they will show how microbes can survive in extreme conditions. Forty different kinds of microbes and some viruses were found in the underground area. The genetic structures of these organisms are 10 percent different from those of their nearest relatives.
The caves in Naica are 800 kilometers deep. They were once used for mining lead. Before the miners began working in the caves, the area was separated from the surface and the outside world. Some of the caves are as big as the large religious centers built during Europe's Middle Ages. There are crystals covering the walls. The caves are so hot that scientists must wear special clothing to keep cool. The clothing keeps the crystals safe from human germs(病菌)or other damage. Boston said the researchers could only work for about 20 minutes at a time before they had to go to a room that was 38 degrees Celsius to cool down.
NASA officials would not let Boston share her findings with scientific experts before last week's announcement. So scientists could not say much about the findings. But Norine Noonan, a biologist with the University of South Florida, said she believed them. "Why are we surprised?" Noonan asked. "As a biologist, I would say life on Earth is extremely tough and extremely colorful."
Boston is also studying microbes commonly found inside caves in other countries, such as Ukraine and the United States. These microbes appear to be impossible to kill. Boston said they show how difficult life on Earth can be.
1.The existence of the ancient microbes relies on _______.
A. surrounding insects B. diverse plants
C. eating minerals D. absorbing air
2.What can we infer about the caves in Naica from the passage?
A. The walls are covered by crystals.
B. The temperature in the caves is quite low.
C. The caves have been explored since they were formed.
D. The environment in the caves is difficult to adapt to.
3.What is the biologist Norine Noonan’s attitude towards the findings?
A. Critical B. Positive.
C. Doubtful. D. Indifferent.
4.What’s the main idea of the passage?
A. Living organisms bring hope to scientific research.
B. Scientists Discover 50,000-year-old “super life” in Mexico.
C. Microbes show great power to survive in terrible conditions.
D. Caves provide living environment for living organisms.

There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community(醫(yī)學(xué)界) a method of fighting heart disease, has had some unintended side (effect) such as overweight and heart disease—the very thing the medical community was trying to fight.
Fat and salt are very important parts of a diet. They are required (process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt 64 (remove) from food, the food tastes as if is missing something. As result, people will eat more food to try to make up for that something missing. Even (bad), the amount of fast food that people eat goes up. Fast food (be) full of fat and salt; by (eat) more fast food people will get more salt and fat than they need in their diet.
Having enough fat and salt in your meals will reduce the urge to snack(吃點(diǎn)心) between meals and will improve the taste of your food. However, be (care) not to go to extremes. Like anything, it is possible to have too much of both, is not good for the health.

When it was announced that Patrick Modiano had won the Nobel Prize in Literature on Oct.9, the Swedish Academy had not yet managed to reach the writer himself to tell him the news. as the Telegraph put it, “It was a curious case of missing personhood in an author whose career had been spent in searching others, within the confines (界限) of a single city.”
Though the 69-year-old French author has had a successful writing career, only six of his books have been translated into English. One reason for this might be that “Modiano’s storylines are as slim as the books themselves”, said the BBC.
While most of Modiano’s works don’t run for hundreds of pages, they explore serious subjects. The author’s signature themes are Germany’s occupation during World War II and the evolution of Paris over the past century.
Modiano’s life has been greatly affected by Nazi Germany’s occupation during the war, and his family’s connections to it. According to New York-based newspaper Forward, his father survived the war dishonorably. When Paris’s Jews were rounded up for deportation(驅(qū)逐)to concentration camps, the businessman did not join them but spent the time making money from deals with Nazis on the black market.
“The novelist has a duty to record the traces of the people who were made to disappear,” French writer Clemence Boulouque, also an expert in Jewish Studies, told The New York magazine.
In his more than three dozen novels, Modiano has returned again and to the same themes: Jewishness, the Nazi occupation, and loss of identity.
Paris is another recurring(重復(fù)的)theme in Modiano’s works .Most of his novels are set in the city , from the rich parts of downtown Paris to more remote suburbs where the characters try to live anonymous protect lives.
Anne Ghisoli, the director of Librairie Gallimard, a bookstore in Paris, concluded, “Modiano is a master of writing on memory and occupation, which haunt(縈繞)and inform his works. He is a chronicler(年代記錄者)of Paris ,its streets, and its present.”
1.According to the article, Patrick Modiano ____________.
A. likes to involve his his memories in his writing
B. usually writes stories with disappearing people
C. is so popular that post of his works are on sale
D. didn’t suffer much during World War II thanks to his father
2.The underline word “slim” in Paragraph 2 is closest in meaning to ____.
A. thin B. hard
C. simple D. dull
3.Which of the following can be the best title?
A. French Author’s Surprise
B. Modiano’s Life and His Books
C. World War II and the Nazis
D. Memory Author Wins the Nobel

On Christmas Eve, 1944, my grandmother urged my uncle, then 12 years old, to slip out of the concentration camp where they were imprisoned near 15 miles east of Vienna to go to Deutsch-Wagram. “People are charitable around Christmastime,” Grandma Lili said to her son, Gyuri. “Ask for some food. Anything they can spare. Tell them that we’re on the edge of starvation. Tell them that your 3-year-old sister can not get off the bed because she’s outgrown her shoes.”
In the dark of that night, Gyuri secretly left the camp and walked nearly four miles to Deutsch-Wagram, the closest town. He happened upon a house and knocked on the front door. A woman opened that door. She was probably alone, her man far away, fighting in the war, her children asleep in their beds. The 12-year-old pieced together in German exactly what his mother had told him to say.
“Come back tomorrow," whispered the woman. The next day, my uncle returned. The woman opened the door with a smile. She piled his hands with bread, clothing, a pair of shoes that her child had outgrown and a pair of socks. The woman had knitted warm socks for my mother. After putting on the socks and shoes that fit, my mother got off the bed in delight. Her ragged shoes were passed on to a younger child who was also living in the camp. They shared their unexpected harvest with the entire camp. It was a quiet celebration of human kindness around Christmastime.
In April 1945, my mother, uncle and grandmother were liberated. And it was those very socks and shoes that my mother wore as she walked some 28 miles over two days to Bratislava on her walk to a new life.
To the unknown giver, I thank you. In the desperation of a cold and snowy land, when many hearts were closed and death was more likely than life, especially for Jews, you gave them hope and comfort.
1.What did Gyuri manage to do on Christmas Eve?
A. Get permitted to go out.
B. Receive food and clothing.
C. Express what his family needed.
D. Celebrate Christmas in the camp
2.Why does the author mention shoes so many times?
A. To prove the truth of the story.
B. To help the development of the story.
C. To attract readers’ attention to the story.
D. To make clear the background of the story.
3.What feeling did the author write the text with?
A. Desperation. B. Gratefulness.
C. Excitement. D. Sorrow.
4.What is the passage mainly about?
A. Light in darkness. B. Peace to common people.
C. Courage in face of danger. D. The influence of Christmas.
