Time flies． My summer vacation ended in the blink of an eye， but one thing is still on my mind． From July 25 to 27， I worked as a volunteer at the Wolong China Giant Panda Garden in Sichuan． I experienced the life of being a panda keeper．
My work included cleaning the pandas' home， feeding the pandas and making food for them． The panda I took care of was named Jingke． When I went to feed him， he would stretch（伸出） one of his forefeet out on a shelf that hung on the fence and wait for his food． He would quickly grab the food as soon as I brought it to him． Can you guess what would happened next？ Jingke would lie down and begin to eat． I could hear him crunching（嘎吱作响地咀嚼） on his food and see him twisting his body around like a dancer． It was really cute． This was one of the most interesting things I saw when I worked there．
When I fed Jingke， I touched his fur（毛）． Most people think that panda's fur would be soft． But actually， panda's fur is very hard． I felt like I was touching needles．I looked at his teeth， too﹣ they were sharp and big． No wonder the panda keepers told us that pandas are not only cute， but also dangerous．
I am happy to be so close to the pandas． This experience lets me know that it is no easy to be a panda keeper．

Mark Zuckerberg， who starts the social network Facebook， often wears jeans and a T﹣shirt to work， including to important business meetings． Not everyone agrees with him． Some people say he doesn't look serious this way．
Harvard Business School researcher， Franccsca Gino， has a different idea． While most people seem to think that dressing differently from those around you generally has a bad influence， shebelieves it can actually have a positive（积极的） effect． And she's done experiments to support her idea． When her researchers， wearing sportswear， visited the expensive shops an Italy， they were usually viewed as wealthier and more important people than those who were well﹣dressed in designer clothes．
Do people always view less formal（正式的） clothing more positively？ Researchers in France took their research out into the street， to the general public． The video they made shows an actor dressed in a well﹣cut suit and shiny shoes． While walking along the road， he begins to cough badly， stops to catch his breath and falls down． Before he even calls for help， people rush to help him． In another video， the actor appears at the same crowded place and repeats the actions in exactly the same way． But this time， no one comes to help． What's the difference？ He's wearing untidy clothes and looks like a homeless person． In a situation like this， the clothes you're wearing could mean the difference between life and death．
It seems that our clothing doesn't only change the way others view us， but also the way we see ourselves． In an experiment testing students' ability to pay attention to details（细节）， the group wearing white lab coats did the best．Why？ Researchers told them that they were wearing the doctors coats． The experiment didn't show whether such influences would last long． More experiments are needed in the future before we decide to make the doctors' coats a must of fashion．

Dogs are very sociable（合群的） animals．When owners go out and leave their dogs alone，the dogs get worried and upset．Dogs should be trained to be their own while still young instead of when they are older and set in their ways．When owners are not around，they should provide some toys for their dogs to play with．Leaving the radio or television turned on might also provide relaxing background noise．
Howling（嚎叫） is a form of communication．Dogs do it to tell one another where they are．Some dogs howl when they are lonely，while others do it when greeting strangers whom they are seeing for the first time．Some even howl to music and do this because it is fun．
When it comes to training dogs，giving rewards（奖赏） is a far better way than using punishment．Food makes an excellent reward，and if they do not respond（反应） to this，owners should try touching．Dogs like being touched by owners very much．Words of praise work well too，but not as well as food or touch．It helps if owners spend more time with their dogs．

Everyone faces difficulties in their life． Daniel Kish was born with a special eye illness and lost his eyesight before he was only 14 months old．
Soon after， however， he started to do an amazing thing． He learned to make clicks（咔哒声） with his tongue to help him move around． Kish now moves about using sonar（声呐）． He is so good at it that he can ride a bicycle by himself on public roads． And he started the organization World Access for the Blind（WAFTB） in 2000， teaching others how to use sonar． In the interview with National Geographic， he explains how the sonar works．
"When I make a click sound， it produces sound waves． These waves reflect（反射） off surfaces all around and return to my ears． My brain then deals with the sound and turns it into pictures in my mind． Each click is like a camera flash， which helps me make a 3﹣D picture of my surroundings for hundreds of feet． It's like having a conversation with the environment．"
Kish feels it is exciting to ride a bike using a sonar， although he needs to click twice a second， much more than he usually does． "It may sound a bit dangerous to move around the world in this way，" he says． "But most people in the world live in fear of things that they imagine． I love hiking and mountain﹣biking． I go almost everywhere． And I've never had an accident and hurt myself．"
He is happy to be able to help more blind children to improve their life．"We've served over 10， 000 students in nearly 40 countries，" he tells the reporter．"Many students are surprised how quickly results come． Seeing isn't in the eyes． It's in the mind．"

Fresh green grass． Hundreds of colorful wild flowers． Water running into little pools． Birds making their homes in boxes． The 9， 500﹣square﹣metre Augustenborg Botanical Garden may look just like any other well﹣organized park but there's a difference． It lies on the roofs（屋顶） of industria land office buildings in the city of Malmo in Sweden．
Green roofs are not a new invention． And now they are getting popular again． The common roofs of a modern city have endless black surfaces with no life or water． Perhaps that's why a garden on a roof becomes such a perfect choice for more and more people．
Green roofs are not just pretty． They also help to moderate the city temperature． The high temperatures on common roofs in the summer can make top floor flats uncomfortably hot． What is more， they play a part in making the cities hotter than the countryside around them， causing the "urban heat﹣island effect"． On a green roof， however， with its plants and water， temperatures change only a little， as they do in a park． This can greatly cut the costs of heating and cooling in the building below．
Also， a green roof takes in rain water， and protects the city drainage（排水） system．_____ And small animals and birds can make their homes on it． Thanks to this， the city may become part of nature， rather than something completely separate from it．
While the cost of building such a roof can still be higher， it can be cheaper in the long term as a result of energy savings． And wouldn't it be wonderful to be able to walk out into a garden high above the city's noise and traffic， whether you're at school or in an office or just at home in a ten﹣floor block．
（1）With the example of Augustenborg Botanical Garden， the writer wants to explain ．
A． how wildlife is protected
B． what a green roof is like
C． how to organize a good park
D． what to do with a spare roof

B． A green roof stops pollution．
C． A common roof is noisy．

（4）The purpose of the passage is to ．
A． discover the problems with green roofs
B． introduce the change of green roofs
C． show the amazing beauty of green roofs
D． describe the advantages of green roofs
