Did you know that something as simple as the wallpaper on your computer can tell people a lot about you? According to researcher Donna Dawson,our computers say something about what we're like because they are part of our “personal space.”

    A picture of a child or family on the screen often means the person cares deeply about their loved ones.A photo of the person surrounded by friends shows they value their popularity and probably work well with other people.On the other hand,pictures showing examples of past successes,like winning a prize may mean a person is only interested in themselves.

    Pictures of nature and natural scenery tell people that you are driven to succeed and use the pictures to relax and remove the pressure（压力）in your life.Cityscapes,pictures of cities or towns,show that you enjoy travel and adventure.Most people with cityscapes as their wallpaper are optimistic（乐观的）,happy people who feel even better thinking about the places they've visited or want to visit.

    Pictures of animals show that you are optimistic and kind-hearted.You are often happy and you enjoy life and act young.Cartoons（漫画）or drawings show that you are a multitasker,someone who does many things at once.You have many responsibilities,but you deal with them well.That's one reason you like having something to smile about when you look at your computer wallpaper.

    Then,what does plain blue wallpaper tell us about a person?According to Dawson,a person with plain blue wallpaper probably values their privacy and keeps work from becoming too personal,

    “Long time no see” is a very interesting sentence. When I first read this sentence from an American friend's email, I laughed. I thought it was a perfect example of Chinglish.

    Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too surprised to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing “Long time no see.” This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily. Ironically, if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected.

    Nobody knows the origin of this Chinglish sentence. Some people believe that it came from Charlie Chan's movies. In the 1930s, Hollywood moviemakers successfully created a world wide famous Chinese detective named “Charlie Chan” on wide screens. Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius. “Long time no see” was his trademark. Soon after Charlie Chan, “Long time no see” became a popular phrase in the real world with thanks to the popularity of these movies.

    Some scholars refer to America as a huge pot of stew. All kinds of culture are mixed in the stew together, and they change the color and taste of each other. American Chinese, though a minority ethnic(少数民族的成员) group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew.

    You can have some other examples than adoptions（采用）from Chinese, such as pizza from Italian, susi from Japanese, and déjà vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant, or to buy a bottle of iced Chinese green tea with honey in a grocery store. Since Americans appreciate Chinese culture more and more nowadays, I believe more Chinese words will become American English in the future. In this way the American stew keeps adding richness and flavor.

    When we think someone is smart，we say they have a big brain．But are there any facts to prove that statement？

    Yes! In a new study done by Michael McDaniel, a psychologist at Virginia Commonwealth University，bigger does mean smarter. "For all ages and sex groups，"he says，"it is now very clear that intelligence has something to do with brain volume（容量）．"

    McDaniel reached his conclusion after measuring the size and volume of 26 brains with the help of some instruments. He then used standard IQ tests to measure the intelligence of the owners of these brains.

    But do IQ tests really reveal intelligence？McDaniel believes that they do，and here are other studies to backup that point of view．One study last year found that IQ is related to the amount and distribution（分布） of gray matter in the brain．The study showed that the amount of gray matter in certain places was strongly related to high IQ．The distribution of gray matter in the brain，which is different for different people，could explain why one person with a high IQ is good at math but poor at spelling，while someone else with the same IQ has just the opposite ability．

    Yet another recent study found that women have more gray matter（compared with white matter） than men！However，the study also showed that in the areas of the brain specifically（特别地） related to intelligence，men had much more gray matter，which is needed for some tasks，such as doing a math problem. Women, on the other hand, had more white matter, which is necessary for collecting information．And the point is that intelligence can be influenced in different ways．

    "On average，"McDaniel says，"smarter people learn more quickly，make fewer mistakes，and are more productive．"He believes in the use of IQ tests to examine those who want to find a job. So, be well, do good work, and…exercise that brain!

    Before you were my teacher, I thought that teaching was the last thing I wanted to do. Why would someone want to come in every day and attempt to instruct students, many of whom couldn't care less, or to get paid very little compared with the work he or she put in?

    You may have thought that the only thing I was learning from you was the course, but that's not all l learned. From reference books to funny jokes, you made each class exciting. You always tried to make class charming so that we could be excited about learning. However, those days have gone by.

    Whenever I was confused and needed extra help, you were the exact one to turn to. I would walk into your room for help and there would be several kids. You ran from one student to the next helping each one through their confusion. You could have gone back home after the bell rang. Instead, you chose to Stay and care about what your students did.

    You didn't only care about my learning, but you also cared about other things I was involved in. At the beginning of the year, we wrote down our hobbies and interests. You remembered what we wrote, too. I had missed class for track meets (田径运动会)and when I came back the next day, you would ask me how it went. Many of the teachers never bothered to ask what I liked to do.

    These things showed me the value of teaching. They showed me how much of an influence a teacher can have on a student. I want to be the one that influences students and pushes them toward success. I want students to leave my classroom thinking that their time was worthwhile (值得的). I want to be the inspiration for them that you were for me. Whenever it gets hard for me to continue on this path, I'll remember you and what you did for me.

    On average, primary school children in England have at least three sugary snacks a day, Public Health England (PHE) found. This means that the sugar they consume is three times more than the recommended maximum.

    Children between the ages of 4 and 10 consume 51.2% of sugar from unhealthy snacks. PHE has launched a campaign, Change4Life, to encourage parents to look for healthier snacks of no more than 100 calories, and to limit them to two a day. The campaign advises parents to give their children a maximum of two snacks a day, with each containing no more than 100 calories. The campaign will also offer parents special suggestions on a range of healthier snacks—ones with 100 calories or fewer—at selected supermarkets, PHE said.

    PHE said it had also improved its app so that it could mark the content of sugar, salt and fat in food and drinks. Dr Alison Tedstone told the BBC she hoped the campaign would help parents to choose healthier snacks for their children. “If you wander through a supermarket, you can see much more goods being sold as snacks than ever before,” she said, “It's a common phenomenon that kids' lunchboxes are full of snacks, leading to a lot of calories for lunch. Our research shows that parents usually appreciate a rule of thumb (经验法则). However, they are surprised to know how much sugar their children are consuming in snacks now.”

    Justine Roberts, founder of Mumsnet, said, “The intake (摄入量) of sugar that kids are getting from snacks and sugary drinks alone is pretty astonishing, and it can often be difficult to distinguish which snacks are healthy and which are not. The rule of thumb from Change4Life can help parents make their decision correctly and wisely. ”

    First aid is defined as the emergency care given to a sick or injured person. The goals of first aid are to prevent death and to prevent injuries from becoming worse. Each emergency condition is different. However, the following rules apply to any kind of emergency.

    Be aware of your limitations. Do not try to do more than you are able to. Nor should you do things if you are unfamiliar with them. Do what you can under the conditions at the time.

    Stay calm. Acting calmly will help the victim feel safe.

    Take a quick look to see if the victim is bleeding, and if there is a pulse.

    Keep the victim lying down and do not move him or her. You could make an injury worse if you move the victim.

    Call for help or ask someone to make the EMS system (急救系统) start.

    Keep the victim warm. Cover the victim with a blanket. Coats and sweaters can be used if a blanket can not be found.

    Reassure (使……安心) the victim. Explain what is happening and that help has been called.

    Do not give the victim any food or fruits.

    Keep the bystanders (旁观者) away from the victim. Bystanders want to have a look, offer advice, and say something about the victim's condition. The victim may believe that the condition is worse than it really is.
