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．

6．Everyone is familiar with white fat，which serves as an energy warehouse．Many mammals also have brown fat，which has the unique ability to produce heat．
Brown fat is sometimes mistaken for a type of gland （腺），which it resembles more than white fat．It varies in color from dark red to tan．When the animal is exposed to a cold environment，the color darkens．In contrast to white fat，brown fat has numerous nerves which provide sympathetic stimulation （刺激） to the fat cells．
Brown fat is most noticeable in newborn animals，wrapped round the central organs to keep them warm．In humaninfantsit occupies up to 5% of body weight，then declines gradually．Certain quantities of brown fat can be discovered in adult humans，especially when they are exposed to cold temperatures．Most of brown fat in adults is located in the lower neck．
Exposure to cold leads to sympathetic stimulation of brown fat cell．As in white fat，sympathetic stimulation promotes hydrolysis （水解） of triglyceride （甘油三酸脂），with release of fatty acids．In contrast to other cells，including white fat cells，brown fat cells express UCP1，which gives the cell's mitochondria （線粒體） an ability to produce heat rather than ATP．Within brown fat cells，most fatty acids are immediately combined with oxygen in mitochondria and a large amount of heat is produced．
There is only about 50g of brown fat in the neck region and it switches on and off throughout the day as it's exposed to different temperatures or if you exercise or eat．But this capacity is much greater in young children compared with adolescents and adults．
The challenge is now to use the knowledge to find out what might switch on brown fat．If it is switched on，we can benefit from it．Brown fat produces lots of heat by burning calories．Unlike white fat，brown fat does not expand our ageing waistlines．And that's why the race is on to find out more about brown fat，and how humans could use it to our advantage，though we would waste energy unnecessarily，and we would sweat a lot and forever be opening windows．
59．We can learn from the passage that brown fatA．
A．becomes less in amount with age      
B．proves less active in low temperatures
C．exists nowhere but in the lower neck   
D．has nothing in common with white fat
60．The underlined word"infants"in Paragraph 3means"D"．
A．cells    
B．organs    
C．bodies    
D．babies
61．We take special interest in brown fat mainly because it helps usD．
A．save energy         
B．develop power      
C．keep warm        
D．keep our figure．

17．A desert is a beautiful land of silence and space．The sun shines，the wind blows，and time and space seem endless．Nothing is soft．The sand and rocks are hard，and many of the plants even have hard needles instead of leaves．
The size and location of the world's deserts are always changing．Over millions of years，as climates change and mountains rise，new dry and wet areas develop．But within the last 100 years，deserts have been growing at a frightening speed．This is partly because of natural changes，but the greatest makers are humans．
Humans can make deserts，but humans can also prevent their growth．Mauritania is planting a similar wall around Nouakchott，the capital．Iran puts a thin covering of oil on sandy areas and plants trees．The oil keeps the water and small trees in the land，and men on motorcycles keep the sheep and goats away．The USSR and India are building long canals to bring water to desert areas．

5．In this passage，the underlined word"needles"refers toC．
A．small，thin pieces of steel

7．People in some countries are fighting a battle againstA．
A．the growth of deserts
B．desert climate
C．natural changes
D．the disappearance of desert
8．What does the author want to tell us？C
A．Deserts are lands of hardness，silence and space．
B．The deserts of the world are changing from time to time．
C．Man is to take measures to control the growth of deserts．
D．Deserts have grown at a fast pace in the past 10years．

4．Listening to music while you drive can improve your speed and ability to get away from accidents，according to Australian psychologists．But turning your car radio up to full volume could probably make you end up in an accident．The performance of difficult tasks can be affected if people are in loud noise．The experience of  pulling up at traffic lights alongside cars with loud music made some psychologists in the University of Sydney look into whether loud music has something to do with driving．
The psychologists invited 60men and women aged between 20and 28as subjects and tested them on almost the same driving tasks under three noise conditions：silence，rock music played at a gentle 55decibels （分貝），and the same music at 85decibels．
For 10minutes the subjects sat in front of a screen operating a simple machine like a car．They had to track a moving disk on screen，react to traffic signals changing color，and brake （剎車） in response to arrows that appeared without warning．
On the tracking task，there was no difference in performance under the three noise conditions．But under both the loud and quiet music conditions，the performers"braked"at a red light about 50milliseconds sooner than they did when there was no rock music at all．That could mean a reduction in braking distance of a couple of meters actually，the difference between life and death for a pedestrian．
When it came to the arrows that appeared across the visual field，the psychologists found that when the music was quiet，people responded faster to objects in their central field of sight by about 50milliseconds．For the people listening at 85decibels，response times dropped by a further 50milliseconds-a whole tenth of second faster than those"driving"with no music．
"But there's a trade-off，"the psychologists told the European Congress of Psychology．"They lose the ability to look around the whole situation effectively．"In responding to objects that suddenly appeared，people in 85decibel rock music were around 100milliseconds slower than both the other groups．Since some accidents-such as children running into the road-take place without any notice，drivers listening to loud music must be less safe as a result．

47．What does the phrase"pulling up"in Paragraph 1mean？A
A．Stopping．B．Driving．
C．Putting up with．  D．Giving somebody a lift．
48．Where did the researchers do the experiment？D
A．At crossroads．
B．In a crowded street．
C．At a police traffic station．
D．Under the same conditions as those of the streets．
49．Which of the following didn't help the performers to"brake"sooner at red lights？C
A．Quiet music．   B．Loud music．
C．Silence．       D．Rock music．
50．Which of the following is the best way to make driving safer？B
A．Loud music．   B．Quiet music．
C．Silence．      D．Heavy metal music．

14．People are quite sensitive by nature，but only a few of us actually"show it．"The reason why we usually prefer to keep things to ourselves is that we are scared that others may judge us or consider us weak．However，sometimes it is necessary to open up and be honest and direct about your struggles-you cannot get help from others unless you let them know that you need it，and that is usually the most difficult part，since it takes a lot of courage．Here are some tips on finding the courage to open up．
The first and perhaps most important step toward finding the courage you need to open up is to know what your emotion is．You will need to explain your feelings and emotions to the person you are opening up to，and it's truly challenging to name the emotion that you feel deep inside．If you are able to do that，you will see that other people will find it a lot easier to understand and accept the things you have to say．We connect with others through emotions and language．
Another important thing you need to do is to spend more time with other people．Not only will you feel more familiar with them，but you will also learn their reactions，making it a lot easier to find common ground．People react differently to unusual or even shocking news，and when you spend more time with the one who is about to receive the news，you will create an emotional and mental connection with them，meaning that it will be slightly more difficult for them to react negatively．
People are not mind-readers，and we all know how complex the human mind and emotions can get．Not even those who have been close to you for decades are able to know what's going on in your mind，and you should never expect them to be able to．Nobody knows for sure what you want，and only a few people are even curious to find out．Share your experiences，emotions，desires and plans with the other person，rather than waiting for them to guess what is happening deep inside you．
The final tip is to simply relax．It often happens that we create worst possible situations deep inside our minds-situations that remain there most of the time，while the reality is totally different．Make sure never try to assume the feelings，thoughts or emotions of other people-you may be terribly wrong．Let them speak for themselves before drawing any conclusions!
These are the most important tips to carefully consider before opening up to someone about a serious emotional matter．
（81）Tips on Finding the Courage to Open Up
Introduction●We seldom show that we are sensitive，because we don't want to be （82）judgedor considered weak．
●Open up and be honest and direct about your struggles，（83）or\otherwise you cannot get help from others．
TipsKnow what you're feeling（84）Name the emotion that is deep inside you，and other people will find it a lot easier to understand and accept what you have to say．
Spend more time together●Spend more time with other people，and you will not only feel more （85）familiar with them，but you will also learn their reactions and find common ground more easily．
●Connect with them emotionally and mentally，which helps them react positively．
Never expect anyone to （86）read     your mindNo matter how （87）close they are to you，they can never figure out what is happening in your mind．
（88）Relax●The reality is totally （89）diifferent from the worst situations you have imagined．
●It is unwise of you to assume others'feelings，thoughts or emotions-let them speak for themselves，instead．
ConclusionYou should take these tips into （90）carefulconsideration before opening up to someone．
