Owning a smartphone may not be as smart as you think. It may let you surf the Internet, listen to music and snap photos wherever you are…but it also turns you into a workaholic, it seems.

     A study suggests that, by giving you access to emails at all times, the all-singing, all-dancing mobile phone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles.

     The study by technology retailer Pixmania reveals the average UK working day is between 9 and 10 hours, but a further two hours is spent responding to or sending work emails, or making work calls. More than 90 percent of office workers have email-enabled phones, with a third accessing them more than 20 times a day. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers confess(承认) they are on call almost 24 hours a day, with nine out of ten saying they make work emails and calls outside their normal working hours. The average time for first checking emails is between 6 a.m. and 7 a.m., with more than a third checking their first emails in this period, and a quarter checking them between 11 p.m. and midnight.

     Ghadi Hobeika, marketing director of Pixmania, said, “The ability to access literally millions of apps has made smartphones invaluable for many people. However, there are drawbacks. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people literally cannot get away from work. The more constantly in contact we become, the more is expected of us in work.”

Next time you're in a public place, count how many people are using their phones. I can tell you now that it is probably more than half.

   I'm not saying that I am not an example of this, but it always amazes me how people can spend so much time on their phones without actually talking to anyone in particular. With the constant upgrade of technology we can now do practically anything on a device which can fit in the palm of our hands. But has it gone too far?

   For example, I was recently on the tube in London. Apart from the people asleep, almost everybody else was on their phones. Of course, being underground it is difficult to get any signal, which rules out texting or using the Internet, but there is still plenty you can use your phones for. People were playing games, reading articles and listening to music, and I am sure that as soon as they emerged from the train they would start texting or calling or checking their emails.

   Recently, my smart phone broke and had to be sent off to the warehouse for repair for a week or so. In the meantime I had to use a really old, basic phone just to keep me in touch with my family and friends. All I could do on this phone was sending text messages, making calls and playing one game. And I loved it. I loved being free from the Internet, and I really didn't mind not having constant updates about what my friends were doing or what the latest celebrity story was. It was quite refreshing and it all allowed me to spend more time taking in my surroundings — I could enjoy my time in London more, for example, and I could watch the people around me and really see what was going on.

   However, I knew that as soon as I got my smart phone back I could be one of those people once again. Perhaps I should just go back to using the basic phone and forget I ever got my smart phone back.

        What should we do if one of our classmates suddenly falls ill or gets injured (受伤)? Here are some steps you should follow. But always remember to seek doctors after first aid if the injury is serious.

¤  Broken bones (骨头):

1   Take away clothing from the injured area;

2     Use an ice pack;

3    Don’t move the injured body part while waiting for the doctor to arrive.

¤  Animal bites (咬伤):

1    Wash the bite area with soap and water; pack the injured area with a clean cloth if it is bleeding (流血);

2    If the bleeding has stopped, cover the area with a bandage (绷带) and take the person to the hospital;

3     Make sure you remember what kind of animal, it is so the doctor can find the right way to treat them as soon as possible.

¤  Fainting (昏厥):

1     Have him or her lie with feet lifted a little. Don’t move the body if you think   there might be injuries from the fall.

2    Make sure he or she can breathe and let in fresh air.

3     Wipe the person’s face with a cool towel(毛巾).

¤  Nosebleeds:

1   Have the person sit up with his or her head tilted (倾斜) forward a little. Do not have the person tilt their head back because this may cause heavy breathing or coughing.

2    Pinch (捏) the lower part of the nose (just below the bony part) for at least 10 minutes.

      Recently, I came across an interesting article on the differences between British English and American English. I had a lot of fun reading it and thinking of as many differences as I could as an American.

       Their cars have “bonnets(发动机罩)”，while ours have “hoods”. They park their cars in a “car park” while we leave ours in a “parking lot”. Our “cookies” are their “biscuits”, while their “rubbers” are our “erasers”.

        Then there are the food words. Would you want to eat something called “Toad in the Hole” or “Bangers and Mash” or “Spotted Dick”? I’m here to report they are all very tasty. There are American equivalents(相等物), of course. We’ve got “Shoofly Mud Pie”. What they call “crisps” is what we call “potato chips” and when we ask for “chips” in England we will get what we know at home in America as “French fries”.

      They find it hystericalthat we call the “toilet” the “bathroom” and they really double over(弯腰)because of laughing when we ask for the “restroom”. American ladies in England who ask for the “little girl’s room” or the “power room” will be met with blank stares(茫然的眼神). A “fag” is a “cigarette” in the UK, which can lead to endless confusion(困惑)for British visitors looking for a cigarette in America. Americans on the other hand are endlessly confused by English signs put up over doorways saying “Way Out”. We Americans walk on the sidewalk not the pavement. “Pavement” in America is the actual cement(水泥)the sidewalk is made of.

We’re surrounded by chemistry in everyday life. Sometimes it is easy to see, like when your science teacher does a big experiment in class. At other times, it can be pretty hard to see everyday chemistry at work, but nearly everything you touch or use has some element of chemistry in it.

Something as simple as toothpaste contains at least three chemicals, if not more. It is the mixture of them and its chemical reaction that keeps your teeth clean. Other things you use every day are created by chemistry, such as hair products, shampoo and soap. Adding detergent (洗涤剂) to water involves chemistry. Without chemistry, we would never have known that we need soap to get the oil out of clothes or skin. Chemistry not only helps us make products for use, but it also helps us understand the world around us. Chemistry helps us understand what the ozone layer (臭氧层) i s and how it protects us.

Chemistry also gives us sunscreen to protect us from the sun. Thanks to chemistry, we know bleach (漂白剂) can’t be mixed with vinegar, because it can produce poisonous gas. Without chemistry, we wouldn’t have fireworks displays on important days.

Chemistry plays a big role in food preparation. Cooking food causes it to go through a chemical change. That is why cooked food often tastes different from raw food. Baking is a great example of chemistry. Too much or too little of any ingredient makes a difference to the result of baking, for example, the dough (面团) won’t rise or the cake will be flat.

Chemistry isn’t something that just lives in a lab; it’s something that you meet hundreds of times every day. Knowing how chemistry works will give you a greater understanding of the science behind some of the simplest looking things.

One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

Listen — Listen when they are talking. Don’t say anything unless they ask you a question. Sometimes it’s not necessary for you to have anything to say; they just need someone to talk to about their feelings.

Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don’t do everything they want you to do. Try to take an extra pencil or pen with you to classes in case they forget one. Have a little extra money in your pocket in case they forget something they need.

Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can’t stay with me at my worst, you are sure not to deserve to be with me at my best.” Always remember this! If you don’t want to stay with your friends when they’re in hard times, then you don’t deserve to be with them when they’re having a good time!

Make plans — Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you’ll remember these things when you’re all old!

When it comes to intelligence, human beings are the top dogs of the animal kingdom. But in recent years, scientists have been documenting surprising intelligence and emotional depth in animals ranging from honeybees to elephants. Here are some amazing examples.

Artistic Monkey Business

Janet Schmid, director of the Little River Zoo in Norman, Oklahoma, learned a lot about the intelligence of capuchin monkeys. She and her husband adopted a young male, named Bailey. The capuchin particularly liked taking car rides, insisting that he insert the key and ride in the front passengerˈs seat. Now Bailey has become a devoted painter. He uses brushes to create colorful, abstract paintings, and prefers not to be disturbed.

Prairie Dog Sound

Through avarietyof birdlike sounds, prairie dogs warn each other of approaching creatures. They demonstrate asurprisinglycomplex communication system. In his 25 years of study, Slobodchikoff, a professor of biology, has recorded them pronouncing ten nouns including hawk, deer and coyote, a number of adjectives to identify color, size and shape, and even some verbs to indicate speed.

In an ongoing study, Slobodchikoff learns that their brain contains a very extensive vocabulary. He once used his best prairie dog sound to say coyote, and they justlookedat him in anger as if he had said a bad word.

Ivy League Parrot

One African grey parrot Alex is said to have the cognitive abilities of a five-year-old child. Alex canidentify50 different objects, seven colors, five shapes,quantitiesup to six, and the concepts of bigger, smaller, same and different.

Also Alex is considered to make reasoned decisions. During an experiment, researchers gave Alexdifferent-colored blocks in sets of two, three and six. Whenaskedwhich color group had five blocks,

Alex replied, “None.”And he answered thesamein repeated tests.

Obviously, he interpreted the concept of “none” as an absence of quantity all on his own. That’s a lot like a high school student answeringquestionson a quiz show.

When you travel in other countries, youˈll have to get yourself well prepared to ensure your safety and handle emergencies.

Before you leave, youˈd better:

1  Take out medical insurance policy and learn what the plan covers and whether departure or return to the hometown is covered. Figure out payment choices, such as whether you have to speak directly with the insurance company, before or after treatment, whether you have to pay first and get compensation later.

2  Keep up to date on all required vaccinations (接种疫苗) .

3 Learn about the city or area where you are going to travel. Know how to say street names and landmarks in the local language. Figure out unique climate issues such as altitude, seasonal changes, potentially risky animals and insects.

4  Visit some local hospitals and write down addresses in the local language along with emergency entrance locations; do the same for dental/pediatric (小儿科的) services. Get first aid equipment with necessary medications. Take enough prescribed medication from the home country.

5  Carry a card or note written in both English and the local language listing your emergency contact numbers, name, basic medical information such as blood type and allergies (过敏) .

6  Ensure a reliable means of communication is available and carry an extra phone battery and a charger. Ensure that housemaids, drivers, office assistants, those who work or travel know how to call for medical assistance since they may be the only ones available in an emergency.

7  Make sure to bring all documents and visas along with you. Plan your journey carefully and carry copies of documents ID, insurance policy records, medical records) and keep in a place where someone else could access them in an emergency.
