If you haven’t already, you too should switch to the latest eco-friendly, energy-efficient, energy-saving LED (Light Emitting Diode) lighting. As the world becomes more focused on green issues, everyone should do their part in practicing energy efficiency, recycling, cutting down their CO2 emissions and much, much more. One of the most successful campaigns that started in Australia is the now world-famous“Earth Hour”. 2.2 million of Sydney’s residents turned off their lights for an hour in a mass attempt to save energy. The following year, the same idea was adopted by a whole host of different cities.
This is a great example of a campaign to promote eco-friendly options and energy efficiency. But while it clearly raises awareness, it is not a long-term solution to energy saving across the developed world. A long-term solution can be found in the form of switching to LED lighting rather than the traditional halogen lights(卤光灯) found in a typical home.
Put simply, LED lighting is the future of lighting. LED lamps use up only a fraction of the energy pared to that of regular lamps. They also produce a quality flicker-free light, and will last longer than a regular light with 50,000 hours being realistic. Not only are they longer lasting and more energy-efficient with no sacrifice in light quality, but they may quickly become a possible substitute (替代物) for regular lamps that have been previously installed by homes and businesses.
An ordinary 50 watt low-voltage halogen light on for 4 hours a day would cost $ 25 per year to run. With a life span of around 3,000 hours it will typically stop working at the two-year mark. compared with the regular one, an LED light of 50 watts operating for the same period will cost roughly $ 6 per year to run and last 50,000 hours. That means it won’t have to be replaced for 24 years! It really is a no brainer to switch to energy-saving LED lighting. Plus, you will be doing your bit for the environment by being more eco-friendly.

After mom died, I began visiting my father every morning before I went to work. He was weak and moved slowly, but he always had a glass of freshly squeezed orange juice on the kitchen table for me, along with an unsigned note, reading, ‘Drink your juice.” Such a gesture, I knew, was as far as my father had ever been able to do in expressing his love. In fact, I remember, as a kid I had questioned mom, “Why doesn’t father love me?” Mom frowned, “Who said he doesn’t love you?” “Well , he never tells me,” I complained. “He never tells me either.” She said, smiling. “But look how hard he works to take care of us, to buy us food and clothes, and to pay for this house. That’s how your father tells us he loves us.”
I nodded slowly. I understood in my head, but not in my heart. I still wanted my father to put his arms around me and tell me he loved me. He owned and operated a small scrap metal (废旧金属) business, and after school I often hung around while he worked. He fed scrap steel into a device that chopped it as cleanly as a butcher chops a rack of ribs. The machine looked like a giant pair of scissors, with blades thicker than my father’s body. If he didn’t feed those terrifying blades just right, he risked serious injury. “Why don’t you hire someone to do that for you?” mom asked him one night as she bent over him and rubbed his aching shoulders with a strong smelling liniment. “Why don’t you hire a cook?” my father asked, giving her one of his rare smiles.
Many years later, during my first daily visit, after drinking the juice my father had squeezed for me, I walked over, hugged him and said, “I love you, father.” From then on I did this every morning. My father never told me how he felt about my hugs, and there was never any expression on his face when I gave them.The author’s father always prepared a glass of freshly squeezed orange juice for him because .

Here’s something to think about the next time you ask your teacher for help：trying hard to do schoolwork on your own can help you learn．According to a recent study，the more you try while you are learning new information，the better you can remember it later．
This might surprise you．When teachers are presenting new information，they often give students lots of help．But a new study shows this may not be the best way to support learning．“Don’t be too quick to get help when learning something new，”education expert Manu Kapur said．“Try to work on it yourself even if it means trying different ways．’’
Kapur came up with the idea that trying hard can lead to better learning．Then he tested it out on students in Singapore．He separated students into two groups．In the first group，students were asked to solve math problems with the teacher’s help．In the second group，students were asked to solve the same problems by helping one another，instead of getting help from the teacher．
With the teacher’s help，students in the first group were able to find the correct answers．Students in the second group did not solve the problems correctly．But they did come up with a lot of good ideas．
The students were then tested on what they had 1earned．The group without any help from a teacher scored much higher than the group who had help．Kapur said working to find the answers helped students understand the process(过程)，not just the solution．
Kapur’s advice for kids is to put a 1ot of effort(努力)into learning something new rather than going to your teacher for help．“Simply doing a little work or nothing at all won’t work.”says Kapur．“Try to solve a problem in as many ways as possible．’’What is the best title for the text?
| A．Work Your Mind |

Manu Kapur holds that _______．

Dear Alice,
I heard from you three days ago. I’m all right.
Good news! We moved to a new flat yesterday! There are more rooms here than in our old one. You know, I shared a room with my sister in the old flat. But now I have my own bedroom! It is small but it’s my favorite room! I can be alone in it. I can read books, draw pictures, listen to my radio and play CDs. I can also play games on my computer and send e-mails to my friends.
I also love the new bigger kitchen. I love helping my mother with our meals. Mom cooks well. She always teaches me how to make different kinds of dishes. She lived in China when she was young, so she can cook Chinese food. It’s delicious.

It is a very common thing for a person to have a good friend. My good friend is Diana. She is a rich and proud girl. She often thinks that she is too good for anyone, so nobody wants to be her friend.
One day after school, I was waiting for Diana when Vivien came up to me. She gave me a biscuit. I accepted it. We talked and joked, and from then on, I began to spend more time with Vivien than with Diana. I felt a little uneasy.
After a few days, I went to see Diana with some snacks when Vinien came and sat with me. She offered me a sandwich. She also offered one to Diana, but Diana refused it. She walked away. I was angry with Diana for being so rude(无礼的).

After school, I tried to catch up with Diana. While walking home, I tried to correct her attitude(态度), but she didn’t listen to me. She said, “Go and join your dear Vivien. I know you make a new friend and forget the old one.”
