6.There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them for real!Dream what you want to dream; go where you want to go; be what you want to be,because you have only one life and one chance to do all the things you want to do.
May you have enough happiness to make you sweet,enough difficulties to make you strong,enough sorrow to keep you human,enough hope to make you happy.
Always put yourself in others'shoes.If you feel that it hurts you,it probably hurts the other person,too.
The happiest people don't necessarily have the best of everything; they just make the most of everything that comes along their way.Happiness lies for those who cry,those who hurt,those who have searched,and those who have tried,for they can appreciate the importance of people who have touched their lives.
Love begins with a smile,grows with a kiss and ends with a tear.The brightest future will always be based on a forgotten past,and you can't go on well in life until you let go of your past failures and heartaches.
When yo u were born,you were crying and everyone around you was smiling.Live your life so that when you die,you're the one who is smiling and everyone around you is crying.
Please send this message to those people who mean something to you,to those w ho have touched your life in one way or another,to those who make you smile when you really need it,to those who make you see the brighter side of things when you are really down,to those who you want to let know that you appreciate their friendship.And if you don't,don't worry; nothing bad will happen to you.You will just miss out on the opportunity to brighten someone's day with this message.

3.The German city of Hamburg has announced plans to become car-free within the next two decades.It is an ambitious idea,but city officials obviously feel that the personal motorcar does not fulfill a function that walking,biking and taking public transport cannot.The goal of Hamburg's project is to replace roads with a green network,which will allow people to navigate through the city without the use of cars.
    Banishingthe car from urban areas is becoming a common trend in many European cities.London imposes a"congestion charge"on private vehicles entering the city centre during rush hours.Copenhagen is building bicycle superhighways radiating out from the city centre.These developments combined may make worrying reading for driving enthusiasts.Is the time of the personal car over?
   In the century since the Ford Model T was introduced in 1908,global vehicle numbers have swollen to well over a billion.But according to recent research,the growth may have stopped.
    According to Professor Michael Sivak,at the University of Michigan,"motorization"in the US might have reached a peak in 2008,and that the figures have been on the decline since.
"New York,Washington,Boston,Philadelphia,each have more than thirty percent of households without a light duty vehicle,"says Sivak.In fact,the figures show that fifty-six percent of households in New York (which top the list) don't have a car."I think that will be surprising to most people.It was surprising to me,and I am in the business."
   Sivak thinks a number of factors could be contributing to the trend,including workingfrom home and the movement of populations back to city centers.In China,Beijing and Shanghai are looking at plans to limit the number of new vehicles being registered to control prouth.It's a movement more cities are looking towards,particularly in the US.
56.Why does Hamburg launch the"car-free"program?A
A.To build a greener environment.
B.To fix a worldwide road network.
C.To call on people to take exercise.
D.To replace the public transport.
57.The underlined word"banishing"in Paragraph 2 can best be replaced by"C"
A.putting out                           
B.giving away
C.driving away                        
D.setting out
58.Professor Michael Sivak uses the examples in Paragraph 5D
A.to prove the number of cars has been increasing sharply
B.to persuade American people to give up their way of life
C.to introduce to the readers a new trend in buying cars
D.to show many Americas have already abandoned cars
59.What does Michael Sivak think of the result of his research?B
A.Terrifying
B Amazing
C.Exciting       
D.Disappointing.
60.What can be learned from the last paragraph?C
A.Most people like to work in the countryside.
B.It is only big cities that are taking action.
C.Many factors contribute to the trend.
D.Effective rules have come into effect.

10.A dog-lover has invented a high-tech way of feeding his pet by Twitter(推特,流行社交网络).Computer expert Nat Morris,30,has designed a system to give his pet a"tweet treat"by sending him a Twitter message.
His dog Toby gets some delicious dog biscuits from a computer-controlled food machine whenever Nat sends a message to"@feedtoby".
Nat often works away from home and isn't always able to feed Toby by hand.But his new invention  allows Nat to feed his dog from anywhere in the world.
Nat said,"Toby absolutely loves it.At first he didn't know what was going on.Now he sits underneath the machine,wagging his tail and waiting for the treats to drop."
Nat fills the food machine with small pieces of dog biscuits,but not too many in case four-year-old Toby gets too many messages.And Nat has even equipped his house with an online camera so he can see Toby enjoying the food at his home.
But one problem is that friends and family have been so amazed with the"Tweet treat"machine that.they have starting to send tweets to Toby too.So Nat has had to restrict feeding time to make sure Toby doesn't turn into Tubby.
"People have been sending him food at all hours of the day,so I had to limit it to between 9 a.m.and 9 p.m..I'm thinking of doing an updated one which measures his weight before he is fed,just to make sure he's not putting on too much puppy fat,"explained Nat.
How Nat's Twitter Feeder Works:
When a message is sent to@feedtoby it is received by a mini-computer that is linked to the food machine.
When the mini-computer receives the message,a bell rings and Toby comes running over and sits in front of the feeding machine.Next the machine's motor pulls open a trap door which releases a serving of food.
The doggy biscuits then drops into Toby's food bowl.Finally a digital camera takes a photo of him and sends it back to Nat on Twitter-so he knows Toby has been fed.
 
31.Nat has invented a high-tech way to feed his dog because heC.
A.wants his friends to feed Tody                                 
B.has very strong computing skills
C.is often too busy to feed his dog

A.He doesn't want Toby to get too fat.
B.He fears the machine will run out of food.
C.He wants hid friends to stop feeding Toby.
D.He doesn't want Toby to be woken up at night.

A.sits beneath his feeder all day long
B.is now used to being fed by machine

4.The bicycling craze came in when we were just about at the right age to enjoy it.At first even"safety"bicycles were too dangerous and improper for ladies to ride,and they had to have tricycles.My mother had(I believe)the first female tricycle in Cambridge;and l had a little one,and we used to go out for family rides,all together;my father in front on a bicycle. and my poor brather Charles standing miserable on the bar behind lny mother.I found it very hard work.pounding(轰隆隆行进)away on my hard tyres;a glorious,but not a pleasurable pastinle.
Then,one day at lunch,my father said he had just seen a new kind of tyre,filled up,with air,and he thought it might be a success.And soon after that everyone had bicycles,ladies and all; and bicycling became the smart thing,and the lords and ladies had their pictures in the papers,riding along in the park,in straw hats.
My mother must have fallen off her bicycle ptetty often,for I remember seeing the most appalling cuts and bruises(青肿)on her legs.But she never complained,and always kept these accidents to herself.However,the great Mrs.Phillips,our cook,always knew all about them;as indeed she knew practically everything that ever happened.She used to draw us into the servants'hall to tell us privately:"Her Ladyship had a nasty fall yesterday;she cut both her knees and sprained her wrist.But don't Iet her know I told you."So we never dared say anything.Similar little accidents used to occur when,at the age of nearly Seventy,she insisted on learning to drive a car.She never mastered the art of reversing(倒车),and was in every way an unconventional and terrifying driver. Mrs.Phillips used then to tell us:"Her Ladyship ran into the back of a milk-cart yesterday;but it wasn't much hurt";or"A policeman stopped her Ladyship because she was on the wrong side of the road;but she said she didn't know what the white Line on the road meant,so he explained arld Let her go on."Mrs.Phillips must have had an excellent Intelligence Service at her command,for the stories were always true enough.

5.People believe that climbing can do good to health.Where can you learn the skills of climbing then?If you think that you have to go to the mountains to learn how to climb,you're wrong.Many Americans are learning to climb in city gyms (体育馆).Here,people are learning on special climbing walls.The climbing wall goes straight up and has small holding places for hands and feet.
    How do people climb the wall?To climb,you need special shoes and a harness (保护带) around your chest to hold you.There are ropes (绳索) tied to your harness.The ropes hold you in place so that you don't fall.A beginner's wall is usually about 15 feet high,and you climb straight up.There are small pieces of metal that stick out for you to stand on and hold on to.Sometimes it's easy to see the next piece of metal.Sometimes,it's not.The most difficult part is to control your fear.It's normal for humans to be afraid of falling,so it's difficult not to feel fear.But when you move away from the wall,the harness and the ropes hold you,and you begin to feel safe.You move slowly until you reach the top.
