Everything on Earth that scientists can see, measure or study is made of atoms and atoms are named by what types of elements (元素)they are. You probably know the name of many elements, such as oxygen or hydrogen. In any case, elements are everywhere: You, your -shoes, your desk, cars, water and air are all made of elements.
Now, there's a new kind on the block： copernicium.
This element was officially named on February 19，but the element itself isn't new. German scientists made and observed it in 1996. But in the 14 years since then, other scientists have been working to study and validate (证实)the original findings. Validation is an important part of the scientific process because it shows that a scientific discovery was not a mistake.
All that hard work finally paid off when the element finally received its name, copernicium, from the International Union of Pure and Applied Chemistry. Copernicium is named in honour of Nicolaus Copernicus (哥白尼)，a 16th century Polish scholar who proposed that the earth moves around the sun and that the earth turns on its own axis.
Scientists organize all the elements on a chart called the Periodic Table. Each element gets a symbol and its own number, and copernicium gets the symbol Cn and the number 112. This number means that inside every atom of copernicium are 112 protons (质子). The lightest element hydrogen has only one proton inside each atom. Its 112 protons make copernicium the heaviest known element with a name. It was first observed by Sigurd Hofmann»a scientist in Germany. In 1996, Hofmann and his team had to figure out a way to get all the protons together and stick. They used a machine that can speed up atoms up to 10 percent the speed of light. After a week of working on these high-speed collisions(碰撞)，Hofmann's team found copernicium even though it quickly disappeared.
Now, 14 years after Hofmann's experiment, other scientists are able to make copernicium and validate Hofmann's original work. Scientists are excited about copernicium. If such a super heavy atom can be created, then even heavier elements might be waiting in the future. "One of the exciting things is, how far can we keep going?" says nuclear chemist Paul Karol.

Woman Uses Daughter's Key to "Steal" Car
Charlie Vansant, a college student of Athens, Ohio, who reported that his car was stolen, got a surprise when he learned a woman had mistaken it for her daughter's car and taken it — using her key.
Kate Anderson became an accidental car thief when picking up her daughter's car near an Ohio University building last week. Anderson spotted the Toyota Camry（丰田凯美瑞）and used her daughter's key to unlock the car, start the engine and drive home — without realizing that the car wasn't her daughter's.
When Charlie Vansant left class a short time later, he found only an empty parking spot. He first assumed the car had been towed, but when the police couldn't find a record of it, they took a theft report.
The morning after Anderson took the car, her daughter discovered the Camry in the driveway wasn't hers. Anderson said she was able to find Vansant's name on paperwork in the glove compartment and look up his phone number on the website for the university.
When Anderson told Charlie the car was in her driveway, "It sounded really suspicious at first, as she wanted to hold the thing for ransom (赎金) , ” said Vansant. He eventually went to the house with a police officer, where he was reunited with his car. According to the police report, the case was closed "because of mistaken car identity", and Anderson wasn't charged.
Vansant seemed to blame the car company more than the "thief". "Her key fit not only my lock, but my ignition（点火装置）as well — so high-five for Toyota, I guess." he said.What does the underlined word "towed" mean in paragraph 3?

| D．Mrs. Anderson used her daughter's key to unlock Charlie's car and drive home. |
What does Charlie mean by "high-five for Toyota"?
| A．He is blaming Toyota for the poor quality of car keys. |
| B．He should thank Toyota for returning his car. |
| C．He wants to celebrate with Toyota for getting his car back. |
| D．He thinks highly of Toyota for producing large quantities of cars. |
What is likely to happen next according to the passage?

Plans to expand wind energy into the most scenic parts of Germany are meeting increasing opposition across the country.
Anti-wind campaigners are angry that areas including the forests made famous by the tales of the Brothers Grimm are among the targets for new turbines (涡轮机). For the first time they have formed a national opposition group to thwart the expansion. They say the expansion will damage forests and tourism across the country.
Germany has started a massive expansion of renewable energy since the Fukushima nuclear disaster in 2011 in Japan. The government decided to reduce atomic plants and instead increase the opportunities for green power. As a result, solar farms, biogas plants and wind parks are booming. In 2013, 22% of Germany’s electricity was generated by renewable energy. Wind has played a major part in this change, making up half of the renewable energy in 2013, and the public has been generally supportive. To date, a majority of the 23,000 wind turbines in the country have been built in the flat northern and eastern parts of the country. But now the focus of expansion is on the areas of dark forest in the central and southern areas of Germany.
One such region is the Rheinhardswald in the northern part of the state of Hesse. This is the home of the magical tales of Sleeping Beauty, Rapunzel and others, made famous in the books of the Brothers Grimm. This scenic place is a magnet, attracting hundreds and thousands of tourists from all over the world. But now there are also plans to build up to 200 turbines in this scenic place!
Ann-Kathrin Blankenberg is a PhD student and an opponent of the plans. “It is not because this is the area of Sleeping Beauty,” she says, “I want the green movement, I want green technology, I don’t want nuclear power--- but they should be made in the right way and not by destroying the forests.”
The campaigners argue that putting wind turbines in this area makes no sense. The wind speeds are low and the area is home to some extremely rare birds including the endangered black stork. Campaigners say building turbines here would be disastrous for the birds.Which of the following does NOT belong to green power? _____.
| A．Solar energy | B．Wind energy |
| C．Bio-energy | D．Atomic energy |
What percentage of Germany’s electricity was generated by wind in 2013? _____.

| B．The public prefers wind energy to nuclear energy. |
| C．Most Germans object to building wind turbines all over Germany. |
| D．The central and southern areas of Germany are rich in wind energy. |
What is the main idea of the passage? _____.
| A．Wind parks are increasing rapidly all over Germany. |
| B．The Rheinhardswald is famous for the tales of Sleeping Beauty. |
| C．Expanding wind energy into the land of Sleeping Beauty causes controversy. |
| D．Building wind turbines in the land of Sleeping Beauty area makes no sense. |
From good reading we can get pleasure, companionship, experience, and instruction. A good book may absorb our attention so completely that for the time being we forget our surroundings and even our identity. Reading good books is one of the greatest pleasures in life. It increases our contentment when we are cheerful, and lessens our troubles when we are sad. Whatever may be our main purpose in reading, our contact with good books should never fail to give us enjoyment and satisfaction.
With a good book in our hands we need never be lonely. Whether the characters in it are taken from real life or are purely imaginary, they may become our companions and friends. In the pages of books we can walk with the wise and the good of all lands and all times. The people we meet in books may delight us either because they resemble (相像) human friends whom we hold dear or because they present unfamiliar types whom we are glad to welcome as new acquaintances(熟人). Our human friends sometimes may bore us, but the friends we make in books need never weary us with their company. By turning the page we can dismiss them without any fear of hurting their feelings. While human friends desert us, good books are always ready to give us friendship, sympathy, and encouragement.
Of all the gifts from reading books, the most valuable one is experience. Few of us can travel far from home or have a wide range of experiences, but all of us can lead varied lives through the pages of books. Whether we wish to escape from the seemingly dull realities of daily routines or whether we long to visit some far-off place, a book will help us when nothing else can. To travel by book we need no bank account to pay our way; no airship or ocean liner or stream-lined train to transport us; no passport to enter the land of our heart's desire. Through books we may get the thrill of hazardous adventure without danger. We can climb high mountains, brave the perils (危险) of an Antarctic winter, or cross the scorching sands of the desert, all without hardship. In books we may visit the studios of Hollywood; we may mix with the merry crowds of the Paris boulevards; we may join the picturesque peasants in an Alpine village or the kindly natives on a South Sea island. Indeed, through books the whole world is ours for the asking. The possibilities of our literary experiences are almost unlimited. The beauties of nature, the enjoyment of music, the treasures of art, the triumphs of architecture, the marvels of engineering, are all open to the wonder and enjoyment of those who read.Why do we sometimes forget our surroundings and even our identity while reading?
| A．No one is trying to disturb you there. |
| B．All is so quiet and calm around you. |
| C．The book you read is so fascinating. |
| D．Our life is just far from satisfactory. |
What makes people like their acquaintances in books even more?
| A．They are just like our human friends. |
| B．They are unfamiliar types we like. |
| C．They will never ever abandon us. |
| D．They will never hurt our feelings. |
The word “hazardous” means ______.
| A．“unexpected” | B．“dangerous” |
| C．“imaginary” | D．“unusual” |
What is the most suitable title for this passage?
| A．Reading and traveling | B．Experiencing the world |
| C．Traveling with books | D．Gifts from reading |
In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Bad events like "serious illness of a family member" were high on the list, but so were some helpful life-changing events like marriage.
When you take the Holmes-Rahe test you must remember that the score does not show how you deal with stress ---it only shows how much you have to deal with. And we now know that the way you deal with these events dramatically affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women's magazines ran titles like "Stress causes illness".
If you want to stay physically and mentally healthy the articles said avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many — like the death of a loved one — are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription for staying away from chances as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The idea that all stress makes you sick also takes no notice of a lot of what we know about people. It supposes we’re not active in the face of the difficult situation. But what about human ability and creativity? Many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom and physical and mental pressure.The result of Holmes-Rahe’s medical research tells us _________.
| A．the way you deal with major events may cause stress |
| B．what should be done to avoid stress |
| C．what kind of event would cause stress |
| D．how to deal with sudden changes in life |
The score of the Holmes-Rahe test shows ______.
| A．how you can deal with life-changing events |
| B．how helpful events can change your life |
| C．how stressful a major event can be |
| D．how much pressure you are unde |
Why is “such simplistic advice” impossible to follow according to the author?
| A．No one can stay on the same job for long. |
| B．No prescription is effective in reducing stress. |
| C．People are sure to get married. |
| D．You could reduce stress by doing nothing. |
According to the passage people who have experienced ups and downs may become _______.
| A．nervous when faced with difficulties |
| B．physically and mentally tired |
| C．more able to deal with difficulties |
| D．cold toward what happens to them |
