12．WHAT would you do if you were invisible（隱形的）？To many people，this is a fun question．
Do you think this can be true？With recent talks of making invisibility a reality，this fun question could actually become a real problem for people and their governments to consider．
It has recently been reported that researchers in the United States and England are confident that they understand，in theory（理論），how to create an invisibility cloak（斗篷），similar to the one that Harry Potter received from his father．They have already begun to work on it，and are asking for help in developing the material that would be used to create this invisibility cloak．
"Is it science fiction？Well，it's a theory and that already is not science fiction，"said Professor Sir John Pendry．"It's possible in theory to do all these Harry Potter things，but we should face the challenge，that is our engineering ability．
"Now，no invisibility cloak has been made yet，but the first testing of invisibility technology could be soon，"said Pendry．"We will have a cloak after not too long．"
Though the idea sounds great，it could be a bad thing if it is used in wars．

42．What is the biggest problem if we make invisibility a reality？A
A．Engineering ability．
B．Money．
C．Material．
D．Water．
43．Which of the following words shares the closest meaning with"fiction"in the 4th paragraph？C
A．發(fā)明             
B．理論           
C．小說              
D．機器
44．What is the author's attitude toward invisibility's becoming a reality？C
A．Agree．
B．Disagree．
C．A little worried．
D．We don't know．
45．How is the passage organized？B
A．Topic---Supporting examples        
B．Opinion---Discussion---Description
C．Main idea---Comparison （比較）       
D．Introduction---examples---Conclusion（結(jié)論）

分析 短文大意：如果你是看不見的你會是隱形的？對很多人來說，這是一個有趣的問題．你認為這是真的嗎？最近的討論讓隱形成為現(xiàn)實，最近有報道稱，美國和英國的研究人員聲稱他們在理論上能夠理解如何創(chuàng)建一個隱形斗篷．他們已經(jīng)開始了這項工作．

7．Undoubtedly，it's always a happy moment to get some pocket money．But have you ever thought about how to spend your pocket money wisely？Now let's check out the following tips and learn to spend your money in a b（81）etterway．
Make a list
When you get your pocket money，don't get too happy and impulsive（沖動的）．We all have a lot of things that we want．But do you really need them that much？That's why it is suggested making a list before spending money．Start with the thing you want m（82）ost．You can also write down about how much it costs or how important it is in your life．By doing this，you will see if it is n（83）ecessaryto buy it．
Help others
How about being more selfless and using our pocket money to help others？We all know that there are many people in the world who are in e（84）agerneed of our help．Helping others brings out the best in us and is one of the greatest joys in our lives．So consider using your pocket money to do something useful and helpful，to feel how you can make a d（85）ifference．
Save as much as you can．
There is an old saying，"Money doesn't grow on trees．"If you spend all your pocket money all at once，you'll have no money u（86）ntillyour next"pay day"．Wallets sometimes might not be the best place to save as they tempt you into spending your money．Get a piggy bank or ask your parents to start a savings account for you．Someday when you look b（87）ack，you'll get a strong sense of achievement by saving so much by yourself!Just remember，every penny counts．

17．
Looking for an original way to raise money for charity？Has your school run out of clever and fun ideas？Don't give up．There are several ways to support your favorite charity and enjoy yourselves at the same time．
How about holding a bean bath competition？"How does this help？"you may ask yourselves．Well，it's very simple really-you agree to sit in a bath full of baked beans，then for every minute you stay in it，people pay money!The longer you stay in the bath，the more money you collect for the charity your school has chosen!It's extremely messy，but it's good fun!Just a piece of advice，though．Let your parents know what you're doing．Wear old clothes because they're going to need washing after the competition!
Here's another idea that we used at my school：organize a car wash．Everybody who has a car sooner or later washes it or has it washed．So why don't you and your classmates do the job？The money the car owners pay for having their cars washed will go towards your charity．When we did it，we had an amazing time!At first，some of us were worried about getting wet or dirty and it's true．But we also had fun，and at the end of the day it was really worth it!
On the other hand，if you don't feel like getting wet or messy，but have some musical talent，how about organizing a street concert？Street musicians can make a lot of money and so can you if you've got the talent and courage it takes to play in front of an audience．You just need to find a suitable place （make sure you're allowed to play music in that public place），practise for a few hours with your friends first，and give it a try!
I hope all these ideas have helped you a bit，and if you've got any other great suggestions，we would love to hear them．We can publish them，so other people can use them，too．Good luck!

48．Holding a bean bath competition，you wouldB．
A．a(chǎn)sk yourselves many questions
B．sit in a bath full of baked beans
C．put on old clothes after the bath
D．a(chǎn)sk your parents to wash the clothes

A．He thought they could have fun．
B．He was upset about getting wet．
C．He thought many students were too worried．
D．He thought it was an easy way to collect money．
50．From the passage we can know the writer is aB．
A．parent   
B．student   
C．driver   
D．singer
51．The writer writes this passage toC．
A．a(chǎn)sk readers to do something funny for charity
B．tell readers about charity events they can go to
C．suggest fun ideas for people to raise money for charity

4．What should you do if you want to have a nice photo taken？Whether it's work or fun，the most important thing is lighting．If you get bad lighting，you will look bad，too．Know where the light is．You don't want it below you or above you，you want it to shine directly at you．
The key thing is no shadow（陰影）．If you are being photographed outside，do it in the morning，or wait till the 2o'clock shadow has passed．Also don't let pictures in the magazines stress you out-all the pictures are taken by great photographers．And all the faces have had pimples （丘疹，粉刺） taken out by computers．
Tip your head and learn what angles （角度） work with your face．Everyone is different．So you have to learn what suits you．You can practice in Photo Booth for as long as it is your turn，to learn what angles suit your face．Tip your neck to make it look longer，make eye contact with the camera．No one can look bad if they smile．
For long legs，point one leg into center of the frame and get the photographer to shoot looking up your body．
For just leg shots，lie upside down and raise legs in the air for the best angle．And your legs will look thinner and be in better shape．
Keep shoulders back．
Always have mouth slightly open，enough to put a penny between your lips，as this will make your lips look fuller．
Lower your eyes and then look up just as shutter （快門） is clicked for full eyes．
Try to catch every perfect photogenic moment!

61．What is the most important thing when you take photos？Lighting
62．When is better to take photos outside？In the morning or wait till the 2 o'clock shadow has passed
63．What should you learn when you practice in Photo Booth？Learn what angles suit your face
64．What should you do with your shoulders when taking photos？Keep shoulders back
65．What is the passage mainly talking about？.How to look nice in a photo．

1．There are many kinds of pollution around us，such as air pollution，noise pollution and light pollution．They are all bad for our health，and many people think that air pollution is the most serious．
On October 26，1948，in the small town of Donora，people woke up to find themselves in a stagnant （不流動的） cloud of pollution．The sky wasn't clear any longer．Four days later，when the cloud finally lifted，20people were dead and over half the population-7，000people had become ill．
Air pollution is one of the world's oldest environmental problems．By 1306，smoke was so common in London that the burning of coal wasn't allowed．More than 600years later，it was still a major problem when，in 1952，4000were killed by a week of London's"killer fog"．
Now，at the beginning of the 21st century，we still can't breathe healthily．Although air quality （質(zhì)量） has improved over the past few years，the Environmental Protection Agency （EPA） says that over 125million Americans breathe unhealthy air-almost half of the US population．Bad air causes more people to die than car accidents．Every day，14people in America die from asthma （哮喘）．Asthma is now the most common cause of going to hospitals among American children，and it is becoming more common among adults （成人） as well．
In the world，air pollution is bad for the health of 5billion people a year，according to a study done by Cornell University．That's more than two thirds of the world's population．
Perhaps the day will come when people will be able to breathe clean air in cities．Then the sunlight will no longer be blacked out by a smoke．

61．People in Donora woke up to findA on October 26，1948．
A．the polluted cloud
B.20dead people
C．the clear sky
62．Before 1306，the air pollution in London might be mainly caused byB．
A．the running of machines
B．the burning of coal
C．the moving of cars
63．The underline word"major"means"C"in English．
A．strange
B．simple
C．serious
64．Every dayA people in America die from asthma．
A.14         
B.21   
C.125
65．The article mainly talks aboutB．
A．a(chǎn) terrible disease
B．a(chǎn)ir pollution
C．the world's population．
