A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2,500 pounds.
The machine squirts (喷射) out chocolate and, via computer instructions, allows the user to build any shape they like out of the food. But makers Choc Edge have missed the Easter rush. Even so, they hope the printer will be snapped up by retailers (零售商) immediately they come to the market. Britain’s biggest chocolatiers Thornton’s have already said they are interested. Because of the high cost, however, few individuals are likely to buy one. But the devicecould one day allow people to design their own 3D objects after submitting their designs on a website. Dr Hao, founder of Choc Edge came up with a prototype (原型) last year and has only just perfected it so that it can now go on sale. “We’ve improved and simplified the machine, so now it is really easy to use,” he told the BBC. “You just need to melt some chocolate, fill a syringe (注射器) that is stored in the printer, and get creative printing of your chocolate.”
3D printing is a technology where a three dimensional object is created by building up successive layers of material. The technology is already used in industry to produce plastic and metal products, but this is the first time the principles have been applied to chocolate. The research has presented many challenges. Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles. Dr Hao said, “What makes this technology special is that users will be able to design and make their own products. From reproducing the shape of a child’s favourite toy to a friend’s face, the possibilities are endless. It could be developed to help consumers design many products from different materials, but we’ve started with chocolate as it is easily available, low cost and harmless.” “There is also no wastage as any spoilage (损坏物) can be eaten.” Dr Hao added, “Eventually we may see many mass-produced products replaced by unique designs created by the customer.”
EPSRC chief executive Professor Dave Delpy said, “This is a good example of how creative research can be applied to create new manufacturing and retail ideas. By combining developments in engineering with the commercial potential of the digital economy，We can see the new market prospect (前景)—creating new jobs and, in this case, the chocolate printer is called sweet business opportunities.”Which is the advantage of the chocolate printer?
| A．It is easilyavailable, low cost and harmless. |
| B．It mainly produces children’s favourite toys. |
| C．The user can build the shape they like via computer instructions. |
| D．The designs made by it are the same as many mass-produced products. |
What can we conclude from the passage?
| A．The printer sold well during last Easter. |
| B．The technology of 3D printing promises a good future. |
| C．The printer was perfected and went on sale many years ago. |
| D．It’s the first time that the technology has been used in industry. |
Dave Delpy’s attitude towards the chocolate printer is __________.
| A．doubtful | B．supportive | C．negative | D．critical |
We can conclude that this passage is a __________.
| A．science fiction | B．book review | C．news report | D．travel guide |
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.The underlined word “thwart” can be replaced by_____.
| A．support | B．prevent |
| C．increased | D．promote |
Which of the following does NOT belong to green power? _____.

What percentage of Germany’s electricity was generated by wind in 2013? _____.
| A．11% | B．22% | C．50% | D．60% |
What can be inferred from the passage? _____.
| A．The author is against building more wind turbines. |
| 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. |
The shocking disappearance of Malaysia Airlines Flight MH370 has captured the attention of millions around the world as the search for the airplane and its passengers and crew continues. What happened to the flight’s 239 passengers and crew after the plane left Kuala Lumpur on Saturday? It is becoming an increasingly desperate question as the days pass.
But it’s hardly the first mystery of its kind. Here are some half-solved and unsolved airline mysteries that kept investigators clueless for years.
Air France Flight 447:An Airbus A330 flight from Rio de Janeiro to Paris plunged into the Atlantic Ocean in 2009, killing all 228 passengers and crew on board. But it took a full five days for search and rescue teams to find the wreck（残骸）and another three years for investigators to report that ice crystals had caused the autopilot (自动驾驶仪) to disconnect. The bodies of 74 passengers remain unrecovered.
Amelia Earhart:Ace (王牌) pilot Amelia Earhart disappeared in her twin-engine monoplane Electra over the Pacific Ocean in 1937 in an attempt to circumnavigate the globe. No trace of her plane was ever found even after a multi-million dollar search effort, and Earhart was officially declared dead in 1939.
Flying Tiger Line Flight 739:A U.S. military flight left Guam in 1962 with more 90 personnel headed for the Philippines, but it never arrived. The pilots never issued a distress call, and 1,300 people involved in the U.S. military search never found any trace of wreckage.
British South American Airways:It took more than 50 years to find any trace of the 11 people aboard a 1947 flight that disappeared in the Andes Mountains. A pair of Argentineans rock climbers discovered engine wreckage in the Andes in 1998, and an army expedition later found human remains as well.
Uruguayan Air Force Flight 571:A flight headed to Santiago, Chile carrying 45 passengers and crew crashed into the Andes Mountains in poor weather in 1972, killing twelve people. In the meantime, eight were killed in an avalanche (雪崩) that hit the plane’s wreckage where they were taking shelter, and the rest stayed alive by eating the flesh of the dead before they were finally found more than two months after disappearing out of the sky.The underlined word “plunged” in Paragraph 3 is closest in meaning to _____.

Like any good mother, when Karen found out that another baby was on the way, she did what she could to help her three-year-old son, Michael, prepare for a new sibling. They find out that the new baby is going to be a girl, and day after day, night after night, Michael sings to his sister in Mommy's tummy.
The pregnancy progresses normally for Karen. But complications arise during delivery. Finally, Michael's little sister is born. But she is in serious condition. With siren howling in the night, the ambulance rushes the infant to the intensive care unit at St. Mary's Hospital.
The little girl gets worse. The doctor tells the parents, "There is very little hope. Be prepared for the worst." Karen and her husband have fixed up a special room in their home for the new baby — now they plan a funeral.
Michael, keeps begging his parents to let him see his sister, "I want to sing to her," he says. But kids are never allowed in Intensive Care. However, Karen makes up her mind. She will take Michael whether they like it or not.“If he doesn't see his sister now, he may never see her alive.” She dresses him in an oversized scrub suit and marches him into ICU. The head nurse recognizes him as a child and bellows, "Get that kid out of here now! " The mother, the usually mild-mannered lady glares steel-eyed into the head nurse's face, her lips a firm line. "He is not leaving until he sings to his sister!" Karen tows Michael to his sister's bedside. He gazes at the tiny infant losing the battle to live. And he begins to sing.
"You are my sunshine, my only sunshine, you make me happy when skies are gray”
Instantly the baby girl responds. The pulse rate becomes calm and steady.
"You never know, dear, how much I love you. Please don't take my sunshine away "
The ragged, strained breathing becomes as smooth as a kitten's purr.
Keep on singing, Michael. Tears conquer the face of the bossy head nurse as well as Karen.

Telepathy: Mind-to-mind Contact
Telepathy is the ability to communicate without the use of the five senses (sight, hearing, touch, smell, taste). It’s an instinct (本能) which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct, we’re using resources within the unconscious mind. When the resources of two persons’ unconscious minds link together into the same frequency, we call it Telepathy.
We can either send or receive Telepathy. If you know who is calling before you answer the ringing phone, you are probably a good receiver. If you think of a person and he/she calls you, you are most likely to be better at sending.
You can easily put your abilities to the test. Think of somebody and will him or her to contact you. Be patient. The other person may not be a good receiver, but they should contact you much earlier than would normally be expected. Or whenever the phones rings, but try “feeling” who is contacting you. Don’t guess, but try to feel it with your mind. However, if neither of these work for you, that doesn’t mean that you have no ability of telepathy. As mentioned earlier, telepathy is most likely to turn up in case of emergency.
Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams had a clear connection. These people are probably linking to each other’s unconscious mind.
Telepathy & Relationships. The more people spend time together, the more likely they are to be able to link up to the other’s mind, especially when separated. There are two reasons for this. One is that they understand the other’s mind through time spent together; the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child’s eagerly wanting his or her mother, knowing that this person who would always want to be there for them, and the mother’s deep desire to protect her child from harm.Telepathy turns up when we ____.
| A．think of a stranger |
| B．use the five senses together |
| C．recall things from our memory |
| D．sense a close friend in danger |
You’re better at sending than receiving Telepathy if you ____.
| A．can tell who knocks at your door |
| B．can feel your mom is in danger |
| C．receive a friend’s call as you wish |
| D．dream of a friend dreaming of you |
Which is not the way to help people gain Telepathy?
| A．Help them have a strong desire to communicate. |
| B．Separate them all the time. |
| C．Help them link up their unconscious minds. |
| D．Let them spend much time together. |
