Susan and I loved jazz and we of becoming musicians. We decided to form a band so that we could some extra money by playing and singing in a pub(酒吧). The regulars(常客) there were very kind to us. They we go to record our songs in a studio. We wondered if they were playing a on us as they were often very humorous to each other.
, to our great surprise, everything was and we made our record. Imagine our excitement when we heard it on the radio for the first time! It was almost as as later when we became millionaires. Now whenever we go to the pub, we play our songs and drinks for the regulars. Although we are , we still like to play in the familiar places.
The 2014 Nobel Prize in physics went to three scientists who gave lighting a big change by inventing blue LED lights. A big change in lighting efficiency is under way around the world.
Save and green
LEDs use less energy than other forms of lighting. A typical LED bulb(灯泡) can produce around 83 lumens per watt — a measure of how much brightness you can get from a unit of electrical power — much more efficient than other lighting facilities.
LEDs produce light by passing electric current through a semiconductor, while traditional bulbs pass current through a wire. The wasted heat energy is chiefly why traditional bulbs are so much less efficient.
LEDs also last about 30 times longer than traditional bulbs, and many LED bulb products promise up to 25,000 hours of use — more than 17 years if you used one for about four hours a day.
Lighting the world
The lighting application is not only in homes. LEDs are also being used for street lights, public holiday and decorative displays, commercial buildings, and other large energy users.
Car lighting is another application where LEDs are making progress. LEDs used to be used only for daytime running lights, but now many new cars have LED headlights for night-time use.
LEDs also hold promise for bringing light to the more than 1.5 billion people around the world without access to electricity, the Royal Swedish Academy of Sciences noted. Indeed, several proposed solutions to energy poverty include the distribution of LED lights, particularly solar-powered ones.
Digital displays
Without blue LEDs, the world wouldn’t have back-lit smart phones, TV and computer LCD screens, blu-ray(蓝光) players, many forms of lighting, and countless other products.
In the electronics industry, LEDs provide back lighting for the liquid crystal displays (LCDs) in many smart phones, laptops, and televisions. The LEDs are more energy efficient and allow for very thin displays.
Blu-ray players use blue LED lasers(激光) to read data off a digital optical disc. When these systems switched from using an infrared(红外线) laser to a blue LED laser, it became possible to store five to 10 times as much data.
LEDs are now being explored for their potential to transmit(传送) data from the Internet across open space, similar to WiFi. Such a system could transmit a lot more data than WiFi alone. This high bandwidth is possible because LEDs can turn on and off millions of times per second.
The rise of LED lighting came at a time when people were just starting to be concerned about global warming. Because of LEDs’ energy efficiency, using them for the world’s lighting would have “an extreme impact” on society.
I___________ for Blue LED Lights to win the 2014 Nobel Prize in physics
●They_______ big changes in lighting.
II________ of LEDs
●Save and green
1. Compared with other forms of lighting, LEDs are much more efficient because of the different_________ they pass electric current

Many people believe that classical music is not relevant to young people today . However, this issue (问题) frequently causes heated debate.
Some people say that classical music is associated only with old people .For example, if you look at the audience at a classical concert , the majority is over the age of fifty.
Others say it is more popular than we first imagine . Many young people listen to classical music without realising .It is often used in films and advertisements. For example.a famous piece of classical music was used as the theme music for the 1990 World Cup . Not many people could have given its name , but millions enjoyed it .
Also,some people point out that young people produce new music based on classical ideas: for example, it is said that rap(说唱)music was invented by a classical musician in 1912, but it is now used by young people in pop music.
However, young people point to the fact that classical music has been outstripped(超越) by technology. To play a classical instrument, such as a violin, you need to study hard and practise for hours. Nowadays, you don't need to get aching arms from practising. A teenager can write and make music using a computer program in the comfort of their own bedroom.
A final point to in mind is that the term "classical music" is used to refer to a great variety of music, from jazz to pieces for large orchestras(管弦乐队).This makes it even more difficult to say whether classical music is relevant to young people.
So, it may be only a minority of young people who play classical instruments , but when it comes to enjoying classical music, it depends on the piece of music. It may be more relevant to young people in the modern world than they realise!

The air we breathe is freely available, without we could not survive more than a few minutes. For the most part, air is available to everyone, and everyone needs it. Some people use the air to sustain them while (sit) around and feel sorry for themselves. breathe in the air and use the energy it provides to make magnificent life. Opportunity is the same way; it is everywhere. It is so freely available that we take it for granted. Yet opportunity alone is not enough to create success; it must (seize) and acted upon in order to have value. many people are so anxious to “get in” on a “ground floor opportunity”, as if the opportunity will do all the work that’s (possible). Just as you need air to breathe, you need opportunity to succeed. However, it takes more than just breathing in the fresh air of opportunity. You must make use of it. That’s not up to the opportunity; that’s up to you. doesn’t matter what “floor” the opportunity is on, but matters is what you do with it.
Happy Graduation, Seniors! Congratulations! What’s next? Below is some sociologically-inspired, out-of-the-box advice on work, love, family, friendship, and the meaning of life. For new grads from the two of us!
1. Don’t Worry About Making Your Dreams Come True
College graduates are often told: “follow your passion,” do “what you love,” what you were “meant to do,” or “make your dreams come true.” Two-thirds think they’re going find a job that allows them to change the world, half within five years. Yikes.
This sets young people up to fail. The truth is that most of us will not be employed in a job that is both our lifelong passion and a world-changer; that’s just not the way our global economy is. So it’s ok to set your sights just a tad below occupational ecstasy. Just find a job that you like. Use that job to help you have a full life with lots of good things and pleasure and helping others and stuff. A great life is pretty good, even if it’s not perfect.
2. Make Friends
Americans emphasize finding Mr. or Ms. Right and getting married. We think this will bring us happiness. In fact, however, both psychological well-being and health are more strongly related to friendship. If you have good friends, you’ll be less likely to get the common cold, less likely to die from cancer, recover better from the loss of a spouse, and keep your mental acuity as you age. You’ll also be able to face life’s challenges, be less likely to feed depressed, and be happier in old age.
Having happy friends increases your chance of being happy as much as an extra $145,500 a year does. So, make friends!
3. Don’t Worry about Being Single
Single people, especially women, are stigmatized in our society: we’re all familiar with the image of a sad, lonely woman eating ice cream with her cats in her pajamas on Saturday night. But about 45% of U.S. adults aren’t married and around 1 in 7 lives alone.
This might be you. Research shows that young people’s expectations about their marital status (e.g., the desire to be married by 30 and have kids by 32) have little or no relationship to what actually happens to people. So, go with the flow.
And, if you’re single, you’re in good company. Single people spend more time with friends, volunteer more, and are more involved in their communities than married people. Never-married and divorced women are happier, on average, than married women. So, don’t buy into the myth of the miserable singleton.
4. Don’t Take Your Ideas about Gender and Marriage Too Seriously
If you do get married, be both principled and flexible. Relationship satisfaction, financial security, and happy kids are more strongly related to the ability to adapt in the face of life’s challenges than any particular way of organizing families. The most functional families are ones that can bend. So partnering with someone who thinks that one partner should support their families and the other should take responsibility for the house and children is a recipe for disaster. So is being equally rigid about non-traditional divisions of labor. It’s okay to have ideas about how to organize your
family – and, for the love of god, please talk about both your ideals and fallback positions on this – but your best bet for happiness is to be flexible.
5. Think Hard About Whether to Buy a House
Our current image of the American Dream revolves around homeownership, and buying a home is often considered as a stage on the path to full-fledge adulthood. But the ideal of universal home ownership was born in the 1950s. It’s a rather new idea.
With such a short history, it’s funny that people often insist that buying a house is a fool-proof investment and the best way to secure retirement. In fact, buying a house may not be the best choice for you. The mortgage may be less than rent, but there are also taxes, insurance, and the increasingly common Home Owners Association (HOA) fees. You may someday sell the house for more than you bought it but, if you paid interest on a mortgage, you also paid far more than the sale price. You have freedom from a landlord, but may discover your HOA is just as controlling, or worse. And then there’s the headache: renting makes you avoid the stress of being responsible for repairs. It also offers a freedom of movement that you might cherish.
So, think carefully about whether buying or renting is a better fit for your finances, lifestyle, and future goals. This New York Times rent vs. buy calculator is a good start.

Disability aids are vital to those who suffer problems with executing work with two hands.These are people who have been disabled due to some major sickness or some other problems.In order to help them carry on their work in the normal way, disability aids are manufactured.This helps them make their life a lot easier than what it would have been without these aids.The kind of disability aids that an individual might require depends on the person only.It is the problem that a person faces that decides the aids that he/she will use for carrying out their respective jobs.The following is the list of a few disability aids that come of significant use.
The first and foremost aid is the stocking aid, aiding the individuals suffering from the problem of bending down to reach the foot and wear their own socks.These stocking aids have a gutter(槽) that is made up of plastic material.These gutters are shaped in a certain way along with the attachment of cotton tapes in it.The sock is then put over the gutter.The foot is placed inside the gutter.The cotton tapes help in pulling the socks up the leg and subsequently the sock.In this manner, the sock is worn by a person who has problems wearing it by bending one’s back and reaching the foot.
There are openers that help the people who have problems with their hands or wrists to open bottles of ketchup, jam and other such bottles and jars that necessitates the use of hands and fingers.
The third type of disability aids that comes to our minds are lifts.Now what are lifts? Lifts are certain machines that help in lifting people from specific areas, such as a bathtub or a set of stairs.These lifts are of varied types and come for numerous applications.It is for the individual to decide the type that he/she requires to use.
For people, who have problems in balancing their upper bodies in a stable manner, there is something known as grab rails.These grab rails are installed for those who have mobility problems in their upper bodies.These rails come in varieties of shapes, sizes and angles.These grab rails are available to home users as well, in their different variations.One can purchase and fix one to their homes according to one’s specificities.These grab rails require the act of screwing and drilling in order to fix them to their appropriate place.The prices of these rails also vary according to the variation of their shapes and sizes.
A portable book holder is a much sought-after disability aid.It can be used by anybody for that matter, not just the disabled.These portable book holders are light-weight and can be easily moved about.These holders relieve the strains on one’s hands, necks and shoulders that might occur due to the handling of a book.The holders are provided with extended legs that help in placing the reading material at suitable distance.
Thus with the help of these disability aids, the old and disabled people can make their lives much more convenient and comfortable that would otherwise have been a cumbersome and complex one.

It is not easy to find true friends.Even if you’ve connected with someone,how do you really know he is a true friend?And often you will find that someone who you thought you could trust may have let you down.There are ways you can know if a friendship is true and how you can hold onto that friend.
Generally speaking,a true friend is someone who will be there for you no matter what happens.They will stand by you through bad and good times.They will accept you for who you are without trying to change you,and they will be there to help you grow in new ways.
A true friend will keep you secrets for you trust him.They will be honest and be someone you can depend on.They will listen and be someone you can talk things over with,even if they may not have advice to share with you.
However,friendship is a two-way street.To find true friends and keep them,you must in turn be the same as well.Be there for them in their hard times and share the good times with them.Be someone your friends can depend on as well and offer them the same thing they give to you.A friendship will fall apart fast if only one person is giving and putting all the effort.If you are the only one making an effort,be honest and it works.
Actually,there will be barriers in the road but that is the test of true friendship.If it can survive those barriers,it will be stronger and better than ever.Just as St Thomas Aquinas put it,“There is nothing on this earth more prized than friendship.”
Going on holidays is best choice for the Europeans to relax themselves, especially in the UK. However, much has changed during the past decades(几十年).
One of the most traditional British holidays was the “seaside holiday”. Families got on a train or into a car and traveled to seaside towns nearby to sunbathe on the beach, buy ice-creams and eat fish and chips and so on.
In the late 1970s, more and more British people started traveling to other countries in Europe for their summer holidays (July-August) because the weather wasn’t very good, even in summer. The “package holiday” was particularly(特别地) popular with most families.
In the 1980s and 1990s, young people in the UK became wealthier, so many of them traveled to countries all over the world for their holidays.
These years, especially after the world financial crisis(金融危机), most British people can not afford to spend their holidays abroad. They again begin to choose to stay in their own home and go on a few day trips rather than spending money on hotels. They call this sort of vacation a “staycation”.

What happens when you take about 50 sixth-graders and send them to a nature camp with no access to computers, tablets and mobile phones? A new study suggests that after just five days their ability to understand nonverbal social cues improves.
Nonverbal social cues are the emotional information we pick up from people around us that is not communicated through words. It includes facial expressions, eye contact, tone of voice and body posture.
As children spend more time corresponding with their friends via text rather than talking to them face to face, the researchers wondered whether they were losing the ability to read these important cues.
"The idea for this study came from looking at the way my older child and her friends' older siblings were communicating," said Yalda Uhls, "I've been at parties where the kids are all hanging out, but instead of looking at each other, they are staring at their phones."
Uhls, who is the lead author of the study, wanted to see what would happen if a group of children had to spend an extended period of time communicating completely device-free. She found a public school that sends its sixth-grade class to a wilderness camp near Big Bear for five days. At the camp, the students have no access to electronics.
When the class of about 50 children arrived at the camp, they were asked to take two tests to measure their ability to read nonverbal social cues. In the first, the kids were asked to assess the emotions portrayed in 48 photos of people making faces. In the second test, they watched a video with the sound turned off, and then made a judgment about the emotional state of the actor.
At the end of the five-day camp, the students were asked to take the tests again. The researchers report that over the five days the kids went from making an average of 14.02 errors on the face-recognition test at the beginning of their camp stay to 9.41 errors by the end. For the video component, they went from getting an average of 26% of the emotional states correct to getting 31% correct.
"Honestly, we were pretty surprised that just five days would have that effect," said Uhls. "But we think this is good news because if indeed lack of face-to-face time is changing people's ability to understand emotion, our results suggest you can disconnect for five days and get better."
Uhls said the results of their study suggest that it is important for kids to spend time away from screens, but it doesn't necessarily suggest that all screen time is bad." The main thing I hope people take away from this is that it is really important for children to have time for face-to-face socializing," said Uhls. "I love media, my kids are media-savvy, but it is really important to have a balance."
Directions: Read the following passage. Fill in the numbered by using the information from the passage.
Write NO MORE THAN THREE WORDS for each answer.
Ready to give up long showers, water parks, and unlimited water gushing(喷涌) out of your taps? A new study says more than three-hundred-thirty-five-million people are faced with water shortage now. The oceans are full, of course. But the liquid—fresh, clean water for drinking and watering crops is in short supply in many parts of the world. Rivers are running low, lakes are shrinking, streams have stopped flowing, and groundwater is being pumped dry. However, the demand for water keeps increasing. So there comes inevitably the water crisis!
What is causing the crisis? Experts say it is a complex combination of climate change and rapid population growth. On the one hand, global climate change threatens to reduce water supplies due to decreased rainfall. On the other hand, population growth is driving explosive demand for water, prompting rivers in thirsty countries to be tapped for nearly every drop and driving governments to pump out so-called fossil water.
Lack of water may result in several problems. It may increase health problems. Lack of water often means drinking waters are not safe. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. And lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.
One partial answer to the world water shortage, at least for countries near the sea, is to build more desalination plants that change seawater into fresh water. Another suggested solution is for water-rich countries, such as Canada, to sell water to countries which are poor in water. A third suggestion is for countries to adopt ways of increasing the freshwater supply, such as teaching farmers in Africa methods to get clean rainwater. And nearly everyone agreed that the amount of water on our planet can’t be changed, but the way we use it can be if more people realized the problem. Last and the most important, public should be aware of saving water to defeat the water crisis.

Teenagers today live in a very competitive world. It is more important than ever to succeed at school if you hope to have a chance in the job market afterwards. It’s no wonder that many young people worry about letting down their parents, their classmates and themselves. In trying to please everyone, they take on too many tasks until it becomes harder and harder to balance homework, parties, sports activities and friends. The result is that young people suffer from stress.
There are different ways of dealing with stress. Everyone knows that caffeine, whether it is in the form of coffee or soft drinks, keeps you awake and active. But caffeine is a drug which can become addictive (上瘾). In the end, like other drugs, caffeine only leads to more stress. A better way to deal with stress is to exercise. Research has proved that physical exercise is a good release for stress, because it increases certain chemicals in the brain which calm you down. Making sure you get enough sleep is also an important way of avoiding stress and of staying healthy and full of energy. Another way to avoid stress is to manage your time effectively. It is better to do a few tasks really well than lots of tasks badly. Know your limits and try not to take on too much. Finally, if it all gets beyond your control, don’t panic or get hysterical (歇斯底里). Find the time to sit down quietly and breathe deeply for ten to twenty minutes. Do this regularly, and it will help you calm down.
