9．The Future Body Network
Are you tired of wires that spread all over your desk and make your tea pour onto your keyboard？If so，you may consider using devices（設(shè)備）that use technologies like Wi-Fi or Bluetooth．Neither of them sends information through wires．It sounds perfect，doesn't it？But this is not the end of the story．
Scientists are now trying to use the human body to do a similar job．They have come up with the idea of sending information over the small electric field on the surface of the skin．To do this，a transmitter（傳送器）could be built into your pocket or a portable device like an MP3 player．This transmitter would then use your skin's electrical field to send information to a receiving device．Since this kind of transmission can only go as far as 20cm，the receiver would have to be close to some part of your body．
By using this body network，you wouldn't need a wire to link your MP3 player in your pocket to the headphones in your ears，or to send to your computer the pictures from a digital camera hanging around your neck．Moreover，you can exchange electronic cards or share music files with others by shaking hands，dancing cheek（臉頰）to cheek，or kissing each other．
Now，here comes a question．Why would anyone want to use their body as a network when Wi-Fi and Bluetooth already exist？The answer lies in the fact that with Wi-Fi or Bluetooth，it is hard to limit the signals only to your own use．In a busy place，you can never know who might steal your information．However，body networking is safer．It is hard for other people to pick up signals sent over the surface of your skin since this body network only has a limit of 20cm from your body．Thus，no one else can easily pick up and interpret your signals．
Moreover，the most important use of body networking in the future may well be communication within the body rather than just on its surface．Imagine having a number of small devices implanted under your skin and using them to control your own nervous system．In other words，imagine that you have a powerful in-body computer．What do you think of this idea？Does it sound cool，like being a character in the movie RoboCop？Or would you prefer to be just an ordinary human being？
40．What's the main idea of the passage？D
A．Technology is causing us to be lazy
B．Technology is doing harm to our body．
C．Technology is advancing too quickly
D．Technology is making our life easier．
41．Which of the following is NOT the way to exchange information over the skin？B
A．Shaking hands
B．Looking into one's eyes．
C．Kissing each other
D．Dancing cheek to cheek．
42．The body network is safer becauseC．
A．the information is only important to you
B．the information is stored inside your body
C．the information is sent out only 20cm from your body
D．the information is controlled by your nervous system
43．The movie RoboCop is most likely aboutA．
A．a(chǎn) man that is controlled by a computer
B．a(chǎn) computer that turns into a man
C．a(chǎn) robot that catches a thief
D．a(chǎn) thief that steals a robot．

4．Five steps to better handwriting
Some kids love handwriting，but others hate when it's time to put their pen to paper．Maybe they are worried about their handwriting．Are you one of them？（36）D  Here are five steps that really work!
Get a great grasp
Try this-hold your pencil at the top and try to write your name．Pretty hard？But when you hold your pencil the correct way，writing is much easier．（37）E Hold it in place with your thumb，and your index （食指） and middle fingers．
Let the lines be your guide
Lined paper is your friend!Those lines can help you create letters that are the right size and proportion （均衡）．（38）A Also be sure to fill up the lined space completely．Those capital letters should be from the bottom line to the top one．
Slow down
If your writing is hard to read，try slowing down a little．If you rush，it's hard to control where you stop and start your letters．
Lower the pressure （壓力）
（39）CThat makes it harder to make the smooth lines．Try easing up and don't hold the pencil too tightly．
（40）F
Lots of games require you to write or draw pictures．So even though it's not schoolwork，you're still using the skills you need to control your pen better．

A．So"a"should be half the height of a capital"A"．
B．You've been writing since you were a little kid．
C．Some kids press down really hard when they write．
D．The good news is that just about everyone can improve their handwriting．
E．The best way to hold a pen or pencil is to let it rest next to the base of your thumb．
F．Play games
G．Ask for more advice．

5．Many facts suggest that children a re overweight and the situation is getting worse，according to the doctors．I feel there are a number of reasons for this．
  Some people blame the fact that we are surrounded by shops se lling unhealthy，fatty foods，such as fried chicken and ice cream，at low prices．This has turned out a whole generation of grown-ups who seldom cook a meal for themselves．If there were fewer of these restaurants，then probably children would buy less take-away food．
  There is another argument that blames parents for allowing their children to become overweight．I agree with this，because good eating habits begin early in life，long before children start to visit fast food shops．If children are given fried chicken and chocolate rather than healthy food，or are always allowed to choose what they eat，they will go for sweet and salty foods every time，and this will carry on throughout their lives．
  There is a third reason for this situation．Children these days take very little exercise．They do not walk to school．When they get home，they sit in front of the television or their computers and play computer games．Not only is this an unhealthy pastime（消遣），it also gives them time to eat more unhealthy food．What they need is to go outside and play active games or sports．
  The above are the main reasons for this problem，and therefore we have to encourage young people to be more active，as well as steering them away from fast food shops and bad eating  habits．
 
56．According to the text，what kind of children may eat more unhealthy food？B
A．Those who often do sports．
B．Those who often watch television．
C．Those who often have meals at home．
D．Those who often walk to school．
57．The author thinks that children are becoming overweight becauseD
A．they can't choose what to eat              
B．they are too busy to go out and play
C．their parents often cook meals for them     
D．there are too many fast food shops around
58．The word"steering"underlined in the last sentence most probably meansB．
A．forcing  B．guiding   C．driving   D．moving
59．The main purpose of the text is toB．
A．tell a story   B．provide facts     C．give advice  D．compare opinions．
