Yesterday I went to our local grocery store. I often go to their deli counter, and I understand that it can get a little confused for the workers. So normally none of them ever take the time to smile or seem overly friendly. But yesterday it was completely different. I was pleasantly surprised to be greeted with a very welcoming smile by the young man behind the counter. He never sighed heavily or slumped back and forth like he didn’t want to be there. He was all by himself and quite a long line. But not once did he act concerned about it. He just did his job efficiently and acted very kind the entire time.
I was so impressed that I approached the manager. I explained to her that I often visit the deli counter and I have never been greeted with such kindness. She agreed with me that he was a wonderful person and she thanked me for sharing my feelings with her.
As I was walking away，I could hear her approaching the young man with，“I just got a wonderful compliment(praise) about you.” I couldn't hear everything she was saying，but I knew that she did thank him. I couldn't help but smile!
Later I had to pass by the deli counter to get onions. There was no one there，except the diligent young man. He didn't say anything，he just smiled at me. I realized that I hadn't done a huge deed that day，but that small deed made a small difference to someone．I love seeing people smile. I just received my smile cards and I wish I had one with me that day. Maybe I will drop one off at the deli a different day! It's amazing how good I felt after that.
So，friends，the next time you are in a grocery store，retail store，restaurant，or anywhere that someone is working hard，letting them know in some way can mean so much. I hope you get a smile out of it like I did!

Your smartphone can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little equipment of yours----- it might also spread disease.
“People are just likely to get sick from their phones as from handles of the bathroom, ” Jeffrey Cain, the president of the American Academy of Family Physicians , told The Wall Street Journal.
This may be hard to believe, but scientists reached this conclusion after they tested eight cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms (大肠菌), a kind of bacteria found in human waste , with about 2700 to 4200 units of the bacteria on each phone. The bacteria can cause flu, pinkeye and other diseases . That is right --- your phone is covered in our human waste.
Although computers, keys and pens carry germs (细菌) , our phones get far dirtier. They touch a lot of things, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn’t played Angry Birds or Fruit Ninja while sitting on the toilet?
“Some things that we think are personal are actually more public than we imagine,” Cain said.  What is even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don’t think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease (油脂) , an environment that germs really like.
So how do you keep your phone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone’s surface: wash your hands regularly.

[1] Look at the center circles of Diagram A and Diagram B. Which of the centre circles looks larger?

[2] Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact, they are exactly the same size.
[3]Then look at the picture on the right. What do you see? A vase? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can see them at the same time.

[4]“What’s happening? Is something wrong with my eyes?” You may wonder at what you see. Don’t worry. Here is how it goes:
[5]When we look at things, our eyes send messages to our brains and then our brains interpret the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “Visual illusion(幻觉)”.

[6] Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey J shrunk the kids just make use of illusions.

Natural ways of keeping time


In ancient times, people had to use the sun and the moon to tell time. They got up when the sun came up and worked in the fields until the sun went down.
Man-made things
The sand clock is made of two glass balls joined by a narrow neck. The top ball was filled with sand. The sand slowly moved through the neck into the bottom ball. People knew how much time had passed when all the sand had fallen to the bottom ball.
People also made the water clock. They made a small hole near the bottom of a pot. Then they filled the pot with water. Markings inside the pot showed how much time passed as the water dripped (滴) out of the hole.
Nature’s Clocks in Living Things
◆Animals’ Body Clock
Animals do not need clocks to know time. They have a way of telling time by their bodies. Birds know when to fly to warmer places before winter. Some animals know when to keep more food for the cold winter months. Some fish know when it is time to move up the river and lay eggs.
◆Plants have their own clocks
Plants also have their own clocks to keep time. Plants know when to open flow­ers or when to drop their leaves.
◆The Body Clock in Human Beings
People also have their own body clocks. When we get used to our lives, our body clocks can be very accurate (准确的). It can tell us when it is time to wake up. It can also tell us when to eat or to go to sleep.
