Cell Phones: Hang Up or Keep Talking?

Millions of people are using cell phones today. In many places it is actually considered unusual not to use one. {#blank#}1{#/blank#} They find that the phones are more than a means of communication—-having a mobile phone shows that they are cool and connected.

    The explosions around the world in mobile phone use make some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. {#blank#}2{#/blank#}

    On the other hand, why do some medical studies show changes in the brain cells of some people who use mobile phones? Signs of change in the tissues of the brain and head can be detected with modern scanning(扫描)equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. {#blank#}3{#/blank#} He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

    {#blank#}4{#/blank#} The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

    As the discussion about their safety continues, it appears that it's best to use mobile phones less often. {#blank#}5{#/blank#} Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health.

    Writing an article for your school newspaper can be exciting and rewarding, especially when you proudly see your name in print.

    Decide on a topic. {#blank#}1{#/blank#} If you plan to write a news article for a monthly newspaper, you will need to take into consideration whether the topic will be relevant before printing.

    Attract the readers with a lead. As the beginning of a newspaper story, a lead has to be direct, but it does not mean you don't need to entertain the reader as well.{#blank#}3{#/blank#} Your lead must be short, but it must also state as many of the essential parts of you story as possible.

    Consider the 5Ws and H. These are the meat and potatoes of your news articles. You article must answer all of these questions: Who, What, When, Where, Why and How. Once you have answered these things, you can feel confident.{#blank#}4{#/blank#}

    Write, edit, rewrite and repeat as necessary. So, much about having a successful final product is about being willing to spend time and effort in editing and reviewing process.{#blank#}5{#/blank#} After that, make changes as a result. Having taken some useful suggestions, you are to make your article readable not only for their content, but also for their quality.

Don't believe "Get Rich Quick!". If it sounds too good to be sure— it is! If you get an e-mail that says you can make thousands of dollars in a few days, it isn't true. Most likely it will cost you in the end.{#blank#}3{#/blank#}

Public Speaking Training

    Get a coach

    {#blank#}1{#/blank#}, so get help. Since there are about a billion companies out there all ready to offer you public speaking training and courses, here are some things to look for when deciding the training that's right for you.

    Focus on positives

    Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well. Nothing can hurt confidence more than being told that you aren't doing well. {#blank#}2{#/blank#}, so good public speaking training should develop those instead of telling you what you shouldn't do.

    {#blank#}3{#/blank#}

    If you find a public speaking course that looks as though it's going to give you lots of dos and don'ts, walk away! Your brain is so full of what you're going to be talking about. {#blank#}4{#/blank#}. As far as we're concerned, there are basically no hard and fast rules about public speaking. Your audience can be your friends.

    You are a special person not a clone

    Most importantly, good public speaking training should treat you as a special one, with your own personal habits. {#blank#}5{#/blank#}. Your training course should help you bring out your personality, not try to turn you into someone you're not.

Mystery of Mosquito Flight

    The mosquito is a troublesome and dangerous insect. Their bites itch and can carry dangerous diseases, like malaria, Zika virus and yellow fever. Recently, researchers from Britain and Japan discovered how mosquitoes fly. {#blank#}1{#/blank#}

    Mosquito wings are small and have an uncommon shape.{#blank#}2{#/blank#} So, how is their flight possible? The team of scientists from Britain and Japan solved the mystery. They used high-speed cameras and computer images to understand the mechanics of how the insect moves its wings to stay in the air.

    {#blank#}3{#/blank#} They set up eight super-high speed cameras that take 10,000 images each second. Simon Walker, a researcher at the University of Oxford, explains that normally at least two cameras are needed to record an insect, so they've got enough views of an insect. With two camera views they can then take any point on an insect and calculate its 3-D coordinates (三维坐标).

    Mosquitoes can spread diseases. The insect has two antennae, or tall, thin organs on its head that it uses to feel things. But its antennae and six legs make it difficult to take clear images of the wing movements. {#blank#}4{#/blank#} The extra cameras let the researchers see that the mosquito's wings move eight hundred times each second. That is four times faster than many insects of a similar size.

    Mosquitoes fly by moving their wings in several different directions. The thin top edges of their wings move forward first and then they change direction and move down. The movement looks as if the wings are drawing the number eight. {#blank#}5{#/blank#} Walker says that existing unmanned flying devices do not work very well outside because wind can affect their flight.

    "Insects, on the other hand, deal really well with even quite windy conditions. So understanding how they can do this is going to be advantageous to us." These researchers say that understanding how mosquitoes fly might help find ways to stop them from spreading diseases.

A. Because of this, it is hard to believe that they are able to fly.

B. Mosquitoes evolved from other insects about 226 million years ago.

C. So, the team needed to use eight cameras to view the wings from many directions.

D. Researchers at the University of Oxford took images of mosquito wing movements.

E. Many measures have been tried for mosquito control, for example, getting rid of breeding places.

F. This knowledge, they say, help find ways to stop mosquitoes from spreading diseases in the future.

G. The research team believes the mosquitoes' wing movements could help inventors design new flying devices.

Starting a club of some kind at school can be difficult. But with a good idea, some active friends, and the right knowledge, you can pull it off. {#blank#}1{#/blank#}.

Decide whether you really want to start a club. Once you have strong enough support from your friends and fellow students, you're ready to go.

{#blank#}2{#/blank#}. Find an advisor for your club. Pick someone who will help you organize events for your club.

Find a place. {#blank#}3{#/blank#} If you want to do this,  talk to your headteacher to apply (申请) for a classroom.

Decide when to meet. Decide how often your club should meet, and then pick a convenient time and day when most club members will be free.

Advertise your club at school. Make bright, colorful informative posters (海报) that will attract attention. {#blank#}4{#/blank#}.

Plan volunteering events. You can decide on events yourself, or hold a meeting to get your club's opinion. {#blank#}5{#/blank#}

Have fun. What's the point of having a club if it's no fun? Don't take yourself too seriously and be sure to have a sense of humor.
