If eighteen-year-old Karki doesn't turn out to be the next Edison, I'll chop off my locks This kid invented a solar pane (嵌板) which uses human hair as a conductor and could provide the world with cheap, green electricity, solving the energy crisis.
Karki, a Nepal teenager, who lives in a village in Rural Nepal, used human hair to replace silicon, which is a common but expensive component of solar panels.
By using hair as a replacement, Karki says solar panels can be produced for around 23 pounds. But if they were mass-produced, Karki says they could be sold for less than half that price, which could make them a quarter of the price of those already on the market.
The solar panel works because melanin, the substance giving hair its color, is light sensitive and can act as an electrical conductor. Karki was inspired to follow this route by a Stephen Hawking book, which explained how to create energy from hair.
The device (设备) Karki has shown is able to produce 9V or 18W of energy -- plenty to charge a mobile phone. Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months, where as a pack of batteries would cost 50p and last a few nights," according to Karki.
Karki has now sent out several devices to other districts near his village for testing. "First I wanted to provide electricity for my home, then my village. Now I am thinking for the world," he said.
Karki says the idea is more important than ever because of the urgent need for renewable energies in the face of limited power sources and global warming. Slowly, natural resources are decreasing. One day we will be in a great crisis. This is an easy solution for the crisis we are having today.

It is never too early, or too late, to encourage a child to read. With the chill(寒冷) of winter upon us, the following is a list of wonderful stories with winter and or snow themes.
Waiting for Winter
It was written by Sebastian Meschenmoser. A little squirrel(松鼠), who has never seen snow, is determined that he will not miss it this year. He gets the help of his good friends, a bear and a hedgehog, trying to stay awake until they can all see the first snowfall of winter. This book is a wonderful story to read aloud to young children or for older children to read by themselves.
The Snowy Day
The Snowy Day by Ezra Jack Keats is a short read, but since its first publication it has been loved by millions. It tells about a beautiful story about the magic and possibility of the first snowfall of winter, which appeals to young and older children.
The Polar Express
Popularized by the 2004 Warner Brothers all-digital film, The Polar Express was first published in 1985. The hero of this story is a boy who is given the opportunity to receive a gift from Santa himself. A magical train appears outside his bedroom window, taking him away on a fantastic journey to the North Pole.
Mr. Willowby’s Christmas Tree
It was written by Robert E. Barry. Mr Willowby orders a lovely new Christmas tree, and when it is delivered to his home he finds it far too tall. He has the top of the tree cut off in order to make it just the right height. This book follows the treetop on its journey through the forest, where it brings the joy of the holidays for some woodland creatures. This book teaches us a valuable lesson about the joy of giving, and happiness that it can bring to the hearts of recipients(接受者).Waiting for Winter and The Snowy Day are similar in that ________.

There is a scene in the movie The Descendants and it went something like this ---George Clooney’s character Matt King has a daughter who may be 9 or 10. She said something bad to a girl at her school that made her cry. The mother of that girl made Matt and his daughter come to their house to apologize. “Sorry,” said his daughter very casually. She was clearly not sorry for her actions and the girl’s mother complained she didn’t take her apology seriously. Matt shrugged(耸)his shoulders. What was he supposed to do? His daughter apologized as asked. He couldn’t make her mean her words.
I always think of this story when my daughter is asked by other adults to apologize for her wrong doings. I know my daughter is being taught to say “sorry” with all the best intentions. They are teaching her to be polite. But she is apologizing because she is being forced to please the adult or to avert punishment.
This situation has happened on a few occasions and it really bothers me. Here are three reasons why I don’t think it’s a good idea to teach children to say sorry: 1. My daughter is being taught to say things that are not from her heart. 2. She is being taught insincerity(不真诚) is valued over genuineness. 3. She is being taught she needs to please others to be loved.
These messages make me uncomfortable and I will not ask my children to apologize. Instead, this is what I think people should teach children:
teach them behavior that is acceptable and to practice positive behavior.
teach them how their actions affect others.
give them space to think about the situation and ask them to suggest ways to make the situation better.
help them make healthy choices
lead by example and show them how to fix wrong doings The story in Paragraph 1 mainly shows that ________.
| A．sometimes people don’t take their apology seriously |
| B．The Descendants is a good film that is worth seeing |
| C．forcing a child to apologize may not get expected results |
| D．parents should punish their children for their mistakes |
What does the underlined word “avert” in Paragraph 2 mean?
| A．Suffer | B．Avoid | C．Deserve | D．Get |
From Paragraph 3 we can learn that the author ________.
| A．doesn’t like apologizing to other people. |
| B．doesn’t think apologizing is important to children |
| C．doesn’t think her daughter has done anything wrong |
| D．thinks forcing a child to apologize has disadvantages |
According to the last paragraph, the author suggests people should ________.
| A．teach children how to become independent |
| B．teach children how to apologize in the correct way |
| C．teach children to behave well instead of forcing them |
| D．teach children how to set a good example to others |

Each of us can live strong, healthy, energetic lives for a long time to come. The key？Actually, there are many of them.
Eat fewer calories, but more food
Slimming down can help prevent disease, and cutting way back on the amount you eat may even slow the aging process. When nutrition researchers invited themselves over for dinner in kitchens across the globe-from Greece to Japan to the state of Pennsylvania--they discovered a stomach-satisfying secret to good health：Pile your plate high with vegetables and fruits, add respectable parts of beans and whole grains, and ignore high-calorie food like cheeseburgers, cream sauces, and fatty meats.
Use exercise as an anti-aging vaccine
Exercise can help you gain a better quality of life as you age. It's no secret that physical activity strengthens muscles, burn calories, and puts a happy bounce in your step. But recently, researchers discovered a new, extra benefit：Exercise acts as a powerful way against the aging process itself. When exercise physiologists put healthy people aged 60 to 85 on Weight-training programs for six months then tested them for signs of free-radical(自由基) damage, they were surprised by the results. By the end of the study, low-intensity exercisers had a drop in free-radical damage, while high-intensity exercisers had a slight increase.
Find something interesting to do
Life is always busy no matter what your age. But the truth is, when people are retired, time usually does become more available for adults after 60. With this time come choices. The easy one is merely to relax：watch more TV, eat out more often, talk on the phone as much as you want. The better choice? Discover something more meaningful to devote yourself to and do it wholeheartedly.Which of the following is what you should eat more?
| A．Fatty meats. | B．Whole grains. |
| C．Cream sauces. | D．Cheeseburgers. |
The new discovery of exercise probably is that__________.
| A．it can help you live a better life |
| B．it can strengthen muscles |
| C．it can burn calories |
| D．it can prevent aging process |
When do you have more free time according to this text?
| A．In your fifties. | B．Beyond sixty |
| C．Over seventy | D．Before sixty. |
The best title of this text should be "_______".
| A．How to Keep a Balanced Diet |
| B．The Importance of Your Health |
| C．Keys to living Longer and Better |
| D．Hobbies making Your Healthy |
Everywhere I look outside my home I see people busy on their high-tech devices, while driving, walking, shopping, even sitting in toilets. When connected electronically, they are away from physical reality.
People have been influenced to become technology addicted. One survey reported that “addicted” was the word most commonly used by people to describe their relationship to iPad and similar devices. One study found that people had a harder time resisting the allure of social media than they did for sleep, cigarettes and alcohol.
The main goal of technology companies is to get people to spend more money and time on their products, not to actually improve our quality of life. They have successfully created a cultural disease. Consumers willingly give up their freedom, money and time to catch up on the latest information, to keep pace with their peers or to appear modern.
I see people trapped in a pathological（病态的）relationship with time-sucking technology, where they serve technology more than technology serves them. I call this technology servitude. I am referring to a loss of personal freedom and independence because of uncontrolled consumption of many kinds of devices that eat up time and money.
What is a healthy use of technology devices? That is the vital question. Who is really in charge of my life? That is what people need to ask themselves if we are to have any chance of breaking up false beliefs about their use of technology. When we can live happily without using so much technology for a day or a week, then we can regain control and personal freedom, become the master of technology and discover what there is to enjoy in life free of technology. Mae West is famous for proclaiming the wisdom that “too much of a good thing is wonderful.” But it’s time to discover that it does not work for technology.
Richard Fernandez, an executive coach at Google acknowledged that “we can be swept away by our technologies.” To break the grand digital connection people must consider how life long ago could be fantastic without today’s overused technology.The underlined word “allure” in Paragraph 2 probably means ______.
| A．advantage | B．attraction |
| C．adaption | D．attempt |
From the passage, technology companies aim to ______.
| A．attract people to buy their products |
| B．provide the latest information |
| C．improve people’s quality of life |
| D．deal with cultural diseases |
It can be inferred from this passage that people ______.
| A．consider too much technology wonderful |
| B．have realized the harm of high-tech devices |
| C．can regain freedom without high-tech devices |
| D．may enjoy life better without overused technology |
What’s the author’s attitude towards the overusing of high-tech devices?
| A．Neutral. | B．Sceptical. |
| C．Disapproving. | D．Sympathetic. |
