You may use banknotes every day. But did you know that there is a lot of science behind the money? 1.

Australia was the first country to use polymer(聚合物）banknotes in 1988. 2.

They can stop water from making them wet. They are also cleaner because bacteria don’t grow easily on them.

Now, the Australians have improved their banknotes again by creating a new 5-dollar note. The new one has a clear window in the middle in which there are pictures of an Australian bird and a building. 3.

Tilt (傾斜）the note a little and you will see the bird flapping its wings as if trying to fly away. Turn the note from side to side and you will notice the building come to life and spin. While these features are impressive and entertaining, that was not the reason why the Australian Government spent ten years perfecting them. Their primary purpose was to make it impossible to fake a banknote.

4. The new $ 5 bill now has a raised bump alongside the two long edges, enabling the blind or those with limited vision, to quickly determine its value.

The Australian government will give the new 10-dollar note the same features in a year’s time. 5.

A. Note makers still have a long way to go.

B. Other notes will have them in the future.

C. The magic of the new features lies in them.

D. They have many advantages over paper notes.

E. The new Australian 5-dollar note is a good example.

F. The new note is also the first touchable Australian banknote.

G. Their material and pattern set them apart from ordinary banknotes.

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.

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.

科目：高中英語(yǔ) 來(lái)源：寧夏學(xué)益校區(qū)2016-2017學(xué)年高一下學(xué)期第二次月考英語(yǔ)試卷 題型：閱讀理解

Dr. Michael Prager, a leading Botox expert, said that a growing number of women are developing something called “computer face”. He also mentioned that professionals who worked long hours in front of a screen were ending up with saggy jowls（顎骨下垂）,“turkey neck” and deep-set wrinkles（皺紋） on their forehead and around their eyes.

The Botox expert said that, of all his clients, office workers were most likely to show premature （過(guò)早的）signs of aging. “ If you are one of the unfortunate people who frown（皺眉）while you are concentrating on the screen then, over time, you will inevitably（不可避免地） end up with frown lines.’’ Dr. Prager said. “What is perhaps more surprising is the number of women with saggy jowls because they are sitting in one position for so long. If you spend most of the time looking down then the neck muscles shorten and go saggy, eventually giving you a second neck.”

Dr. Prager, who has a practice near Harley Street in London, said he encourages his clients（客戶） to put a mirror next to their computer so they can see if they are frowning at the screen. “When people are stressed or thinking hard about something, then they will often put on a ‘grumpy（脾氣暴躁的）face’ without even knowing what they are doing. When my clients put a mirror next to their desk, they are often shocked by the angry, frowning face which stares back at them.”

He said, “The women I am seeing at the moment have only been using computers at work for the last decade or so. But women in their 20s have grown up with them and use them for every single task. I think the problem is going to become much, much worse. In another ten years, they could be looking quite awful.”

Dr. Prager said there were several simple steps which could avoid “computer face” such as regular screen breaks and stretching the neck muscles. And, of course, there was always Botox. He said that , after a couple of sessions of Botox, the habit of “grumpy face” could be broken.

1.According to the passage, which of the following are signs of aging?

A. Saggy jowls and short necks

B. Turkey neck and frown lines

C. Deep-set wrinkles and angry faces

D. Second neck and stressed muscles

2.Why does Dr. Prager suggest a mirror for his clients?

A. To be aware of their “computer face”

B. To see if they have got a second neck

C. To make sure their make-up is perfect

D. To find more signs of premature aging

3.From the last 2 paragraphs, we can know that_____

A. “computer face” is avoidable

B. we should give up using computers

C. we should break the habit of “grumpy face”

D. the younger generation is worse at computers

When the accident was happened, I was standing near a bus stop. There I saw an old lady waiting a bus with her umbrella. The bus soon arrived. There were too many passengers hurried to get on it that the old lady couldn’t get on. A driver closed the door without looking careful and drove away. Unluckily, the old lady’s umbrella was caught by the door. He shouted to the driver but he didn’t hear. The bus pulled her along the road. Finally, she fall to the ground.
