In English it's common to say, "I know this town like the back of my hand!" While we may know our towns really well, how well do we actually know our hands? Maybe not quite as well as we think, said a scientific study.
Matthew Longo and his team from University College London studied the left hands of 100 people. With their hands placed palms(手掌)down under a board, Longo's team gave the instruction to point to their knuckles(指关节) and fingertips with a marker. How did they do? Not that well.
"People think their hand is wider than it actually is," said Longo. He said they also seemed to think their fingers were shorter than their true lengths. People were most accurate when finding their thumbs, but became less accurate with each finger, up to their pinkies.
"It is connected to our sense of position," explained Longo. Humans know where different parts of our bodies are, even if we can't see them. "It tells us whether a joint(关节)is straight or not," said Longo. "We also need to know the distances between our joints," he went on. Our brains know the sizes and shapes of our bodies from the maps they make for themselves. "This experiment tried to find those maps," he said.
Maybe maps don't need to be perfect. But why aren't our brains more accurate? Longo said our brains "see" areas based on our sense of touch, with the stronger the sense of touch in a specific body part, the bigger that body part seems. An example is our lips. As they have more nerves than our noses, our brain's map shows our lips are bigger. The same thing can happen with body parts that have a lot of nerves. If you've ever had something stuck in your teeth, it probably felt huge! That's because our tongues also have lots of nerves.
If you want to have some fun, try this test with your classmates. Get some boards and some markers and have them mark the spots where they think their knuckles and fingertips are. Compare their hands to the marker spots and see how well they have performed.
Forty-three years seems like a long time to remember the name of a mere acquaintance(认识的人). I have forgotten the name of the old lady to whom I delivered newspapers but I can't forget the lesson she taught me in forgiveness .
On a winter afternoon, a friend and I were throwing stones onto the roof of the old lady's house . I found myself a perfectly smooth rock and threw it out. The stone was too smooth, however, so it slipped from my hand as I let it go and headed straight not for the roof but for a small window of the house.
At the sound of broken glass, we knew we were in trouble. We turned and ran away fast. I was too scared about getting caught that first night by the old lady with the broken window. However, a few days later, when I was sure that I hadn't been discovered, I started to feel guilty for her misfortune.
She still greeted me with a smile each day when I gave her the paper, but I was no longer able to act comfortable in her presence. I made up my mind that I would save my paper delivery money, and in three weeks I had the seven dollars that I thought would cover the cost of her window.
I put the money in an envelope with a note explaining that I was sorry for breaking her window and hoped that the seven dollars would cover the cost for repairing it. I waited until dark, and put the letter I didn't sign in her letter box.
The next day, I handed the old lady her paper and was able to return the warm smile that I was receiving from her.
She thanked me for the paper and gave me a bag of cookies she had made herself. I thanked her and ate the cookies happily.
After several cookies, I felt an envelope and pulled it out of the bag. When I opened the envelope, I was stunned. Inside were the seven dollars and a short note that said, "I'm proud of you."
Nowadays, plastic waste is a challenging problem all over the world. Scientist world-wide are working hard to find ways to recycle the plastic wastes to save the earth from the white disaster.
Australian scientists have found a species of worm that can eat polystyrene(聚苯乙烯) could be the key to plastic recycling. Researchers from the University of Queensland in Australia discovered the common Zophobas morio ‘superworm' can eat through polystyrene, thanks to a bacterial enzyme(酶) in their gut(肠道).
Dr Chris Rinke and his team from UQ's School of Chemistry and Molecular Biosciences fed superworms different diets over a three-week period, with some given polystyrene, some grain and others had nothing to eat. "We found the superworms fed a diet of just polystyrene not only survived, but even had slight weight gains, " Dr. Rinke said. "This suggests the worms can get energy from the polystyrene, most likely with the help of the microbes(微生物) in their guts. " "Superworms are like mini recycling plants, tearing the polystyrene into pieces with their mouths and then feeding it to the bacteria in their gut, " Dr. Rinke said.
It's hoped this bio-upcycling will increase plastic waste recycling and reduce landfill. The long-term goal is to engineer enzymes to degrade(分解) plastic waste in recycling plants through mechanical shredding, when plastic waste is torn into pieces , bacterial enzyme from the superworms can finish the enzymatic biodegradation process.
Co-author of the research, Jiarui Sun, said they aim to grow the gut bacteria in the lab and further test its ability to degrade polystyrene. "We can then look into how we can improve this process to a level required for an entire recycling plant, " Ms. Sun said.
Sometimes you may be faced with homework stress and doing homework every day even becomes a heavy burden(负担). However, it can be a satisfying experience if well organized.
Pick a proper time and workplace. Each student is different. Some students are used to doing their homework right after school, while others prefer to start later after a short rest. Different students work best at different time. A good learning environment will also help you concentrate well, so too comfortable or uncomfortable chairs, strong smell or extreme temperature should be avoided.
Figure out how much homework you have to do every day. And list all your homework you have to do in a note book or a day planner. Focus on once task at a time. It's not a good idea to do several tasks at a time as you can't concentrate on several things at the same time. Always do the most important thing first, or you will get stressed if you leave it until the last minute.
Set reminders. As you have got a lot of things going on, it's easy to forget about some tasks. In this way, you can never miss deadlines(最后期限).
Balance your study and life. You need enough time for sleep, well-balanced meals and regular exercise to develop your body and improve your brainpower. Only when you keep a healthy life style can you be more active in your school work.
A. Make a schedule.
B. You are not a machine.
C. Here are some tips to help you.
D. Join a study group.
E. You'd better turn the Wi-Fi off while doing homework.
F. You just find a period of time when you can concentrate well.
G. An alarm clock or a mobile phone to set daily reminder is necessary.
A very special teacher in a high school had a husband who died suddenly of a heart attack.
About a week after his death, she 1 some of her thoughts with a classroom of students. With a 2 look on her face, she paused and said, "Before class is 3, I would like to share with all of you a thought which I feel is very important. Each of us is put here on earth to learn, share, love, appreciate and give of ourselves...and none of us knows 4 this fantastic experience will end. It can be 5 at any moment. Perhaps this is a 6 that we must make the most out of every single day."
Her eyes 7 to water, she went on, "So I would like you all to make me a promise...from now on,8 your way to school, or on your way home, find something 9 to notice. Those can be very little things, although it may sound silly to some people, these things are the stuff of life. We must make 10 important to notice them, for at any time...it can all be taken away. " The class was completely quiet. We all 11 our books and filed out of the room 12.
That afternoon, I noticed more things on my way home from school 13 I had that whole semester.
Every once in a while, I think of that teacher and remember what an 14 she made on all us, and I try to appreciate all of those things 15 sometimes we all overlook.
The Worldwatch Institute says that deforestation(采伐森林) has been speeding over the last 30 years. But, Lomborg, researcher from New York University, says that is simply not true. Since the beginning of agriculture the world has lost about 20% of its forest cover, in recent decades the forest area's reducing has come to a stop. According to UN reports, the area of forests takes up about 30% of total land area , (remain)almost steady since 1940s. Forests in countries such as the US, UK and Canada have (actual) been increasing over the past 40 years. Despite all the warnings the Amazon rainforest has only decreased about 15%.
Nor are all our species (die)out. Some researchers say that 50% of all species will have died out within 50 years. But other studies show only 0.08% of species are dying out each year. Efforts have been made in the past years have been successful. Whales are no longer threatened and the bald eagle (秃鹰)is off the (endanger)list.
Environmental groups state that many of the (improve)are the results of their campaigns. Stephen Tindale, director of Greenpeace UK, said, " is a relief to see that things weren't as bad as predicted, and that's because our behavior changed."

How to keep safe?
As teenagers we should always keep safety in mind.
Andrew and Tina was a happily-married couple who lived in New York. Andrew worked hard every day to support their family and Tina stayed at home to look after their children. Andrew felt lucky to have such a kind and understanding wife as Tina and he was determined to try all out to earn more to make their life better and better.
While Andrew was getting ready for work one Friday morning, he announced to his wife that he had finally decided to ask his boss for a salary raise. Tina smiled at him without a word but her warm smile gave Andrew a lot of courage. However, all day Andrew felt nervous and anxious as he thought about the upcoming showdown. What if Mr. Larchmont refused to accept his request? Andrew had worked so hard in the last 18 months and landed some great accounts for Braer and Hopkins Advertising Agency. Of course, he deserved a wage increase.
The thought of walking into Larchmont's office left Andrew weak in the knees. Late in the afternoon he was finally courageous enough to approach his boss. To his delight and surprise, the ever-frugal（一向节俭的）Harvey Larchmont agreed to give Andrew a raise!
Andrew arrived home that evening—despite breaking all city and state speed limits—to a beautiful table set with their best china, and candles lit. His wife, Tina, had prepared a delicate meal including his favorite dishes. Immediately he figured someone from the office had told her the news!
Next to his plate Andrew found a beautiful lettered note. It was from his wife. It read: "Congratulations, my love! I knew you'd get the raise! I prepared this dinner to show just how much I love you. I am so proud of your accomplishments!" He read it and stopped to reflect on how sensitive and caring Tina was. He felt warm and proud to have such a good wife, and thanked God for that again. He was eager to show his love and gratitude to his wife and he hurried to the kitchen to find her.
