Taking Pictures of the World
Meet Annie Griffiths Belt,a National Geographic photographer.Belt has worked for National Geographic since 1978,and has taken pictures on almost every continent in the world.In fact,Antarctica is the only continent Belt hasn’t seen yet.
Belt’s photographs are well known for their beauty and high quality.They also reflect very different cultures and regions of the world.Belt has photographed the ancient city of Petra,Jordan,as well as the green landscapes of the Lake District in England.Recently,her pictures appeared in a book about undeveloped natural places in North America.
Everywhere that Belt goes,she takes pictures of people.Belt has found ways to connect with people of all ages and nationalities even when she does not speak their language.“The greatest privilege of my job is being allowed into people’s lives,” she has said: “the camera is like a passport,and I am often overwhelmed by how quickly people welcome me!”
Knowing how to break the ice has helped to make Belt a successful photographer,but experts say that anyone can learn to connect with new people.When people speak the same language,greetings and small talk can make strangers feel more comfortable with each other.When people don’t speak the same language,a smile is very helpful.Having something in common can also help break the ice.For example,Belt has traveled with her two children,so when she takes pictures of children or their parents,they all have that family connection in common.Even bad weather can help people to connect when they are experiencing it together.
Belt has some advice if you are thinking about a career in photography.You can volunteer to take pictures for a local organization that can’t afford to hire a professional photographer.You can also take a good,honest look at your best photographs.If you’re a real photographer,your photos are good because of your personal and technical skills.Belt also recommends studying and learning form photos taken by professional photographers.
Remember,the next time you look at a beautiful photograph,you might be looking at the work of Annie Griffiths Belt.And the next time you meet a new person,don’t be afraid to break the ice.The connection you make could be very rewarding.

Keeping Cut Flowers
1 While everybody enjoys fresh cut flowers around his house,few people know how to keep them for as long as possible.This may be done by keeping in mind a few simple facts.
2 An important thing to remember about cut flowers is that they are sensitive to temperature.For example,studies have shown that cut carnations(康乃馨) retain their freshness eight times longer when kept at 12oC than when kept at 260c.Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care.
3 Flowers are not intended by nature to live very long.Their biological purpose is simply to attract birds or insects,such as bees,for pollination (授粉).After that,they quickly dry up and die.The process by which flowers consume oxygen and produce carbon dioxide (二氧化碳),called respiration (呼吸),generates the energy the flower needs to give the flower its shape and colour.The making of seeds also depends on this energy.While all living things respire,flowers have a high level of respiration.A result of all this respiration is heat,and for flowers the level of heat relative to the mass of the flower is very high.Respiration also brings about the eventual death of the flower.Thus the greater the level of respiration,the sooner the flower dies.
4 How,then,to control the rate at which flowers die? By controlling respiration.How is respiration controlled? By controlling temperature.We know that respiration produces heat,but the reverse is also true.Thus by maintaining low temperatures,respiration is reduced and the cut flower will age more slowly.
5 Another vital factor in keeping cut flowers is the quality of the water in which they are placed.Flowers find it difficult to "drink" water that is dirty or otherwise polluted.Even when water looks and smells clean,it almost certainly contains harmful substances that can endanger the flowers.To rid the water of these unwanted substances,household chlorine bleach (含氯漂白剂) can be used in small quantities.It is recommended that 15 drops of chlorine bleach(at 4% solution) be added to each litre of water.The water and solution should also be replaced each day.
23 Paragraph 2 _____
24 Paragraph 3 _____
25 Paragraph 4 _____
26 Paragraph 5 _____
A.Control of Respiration
B.Beauty of Fresh Cut Flowers
C.Role of Respiration
D.Most Important Aspect of Flower Care
E.Need for Clean Water
F.Ways of Stopping Respiration
27 A few simple facts will help you keep cut flowers_______________
28 Respiration plays a key role________________
29 The aging of cut flowers can be slowed down_________________
30 Another important way to prolong the life of cut flowers is ____________________
A.by keeping its original shape and colour
B.in the life of the cut flower
C.to produce carbon dioxide
D.for as long as possible
E.by controlling temperature
F.to replace the water and solution every day

Telling Tales about People
One of the most common types of nonfiction,and one that many people enjoy reading,is stories about people's lives.These stories fall into three general categories: autobiography,memoir,and biography.
An autobiography is the story of a person's life written by himself or herself.Often it begins with the person's earliest recollections and ends in the present.Autobiography writers may not be entirely objective in the way they present themselves.However,they offer the reader a good look at the way they are and what makes them that way.People as diverse as Benjarmin Franklin and Helen Keller have written autobiographies.1Other writers,such as James Joyce，have written thinly fictionalized accounts of their lives.These are not autobiographies，but they are very close to it.
Memoirs,strictly speaking,are autobiographical accounts that focus as much on the events of the times as on the life of the author.2Memoir writers typically use these events as backdrops for their lives.They describe them in detail and discuss their importance.Recently，though，the term memoir seems to be becoming interchangeab1e with autobiography.A memoir nowadays may or may not deal with the outside world.
Biographies are factual accounts of someone else's life.In many senses，these may be the hardest of the three types to write.Autobiography writers know the events they write about because they lived them.But biography writers have to gather information from as many different sources as possible.Then they have to decide which facts to include.Their goal is to present a balanced picture of a person，not one that is overly positive or too critical.A fair well-presented biography may take years to research and write.
练习：
1.This passage is mostly about A .
A.the characteristics of autobiographies，memoirs，and biographies
B.famous autobiographies
C.why biography can be difficult to write
D.differences between autobiographies and memoirs
2.Helen Keller wrote B .
A.a memoir B.an autobiography
C.a work of fiction D.a biography
3.Autobiography writers are not always objective because they C .
A.feel they have to make up details to make their books sell
B.constantly compete with biography writers
C.want to present themselves in a good light
D.have trouble remembering the good times
4.The writer introduces each category in the passage by A .
A.defining it B.giving an example
C.explaining why it is hard to write
D.telling when people first began writing it
5.Diverse means C .
A.able to swim in deep water B.similar or alike
C.varied or different D.enjoying poetry

Outside-the-classroom Learning Makes a Big Difference
Putting a bunch of college students in charge of a $300,000 Dance Marathon,fundraiser surely sounds a bit risky.When you consider the fact that the money is supposed to be given to children in need of medical care,you might call the idea crazy.
Most student leaders don't want to spend a large amount of time on something they care little about,said 22-year-old University of Florida student Darren Heitner.He was the Dance Marathon's operations officer for two years.
Yvonne Fangmeyer,director of the student organization office at the University of Wisconsin,conducted' a survey in February of students involved in campus organizations.She said the desire for friendship was the most frequently cited reason for joining.
At large universities like Fangmeyer's,which has more than 40,000 students,the students first of all want to find a way to ,belong in their own comer of campus".
Katie Rowley,a Wisconsin senior,confirms the survey's findings."I wanted to make the campus feel smaller by joining an organization where I could not only get involved on campus but also find a group of friends."
All of this talk of friendship,however,does not mean that students aren't thinking about their resumes."I think that a lot of people do join to 'fatten up their resume'," said Heitner."At the beginning of my college career,I joined a few of these organizations,hoping to get a start in my leadership roles."
But without passion student leaders can have a difficult time trying to weather the storms that come.For example,in April,several student organizations at Wisconsin teamed up for an event designed to educate students about homelessness and poverty.Student leaders had to face the problem of solving disagreements,moving the event because of rainy weather,and dealing with the university's complicated bureaucracy.
"Outside-of the classroom learning really makes a big difference," Fangmeyer said.
练习：
1.An extracurricular activity like raising a fund of $300,000 is risky because most student leaders D .
A) are lazy B) are stupid
C) are not rich enough D) will not take an interest in it
2.American students join campus organizations mostly for C .
A) making a difference B) gaining experience
C) building friendship D) improving their resumes
3.Who is Katie Rowley? B .
A) She’s a senior professor B) She’s a senior student
C) She’s a senior official D) She’s a senior citizen
4.What do student leaders need to carry an activity through to a successful end?A
A) Passion B) Money C) Power D) Fame
5.The phrasal verb fatten up in paragraph 6 could be best replaced by C .
A) invent B) rewrite C) polish D) complete

Shark attack!
Craig rogers was sitting on his surfboard,scanning the distance for his next wave,when his board suddenly stopped moving.he looked down and was terrified to see a great white shark biting the front of his board.” I could have touched its eye with my elbow,” says craig.The shark had surfaced so quietly that he hadn’t heard a thing.
In his horror and confusion,he waved his arms and accidentally cut tow of his fingers on the shark’s teeth.He then slid off the opposite side of his surfboard into the water.Then,with Craig in the water and blood flowing from his fingers,the five-meter-long shark simply swam away,disappearing into the water below.
Although sharks are often categorized as killers that hunt and eat as many humans as then can,this is factually inaccurate.Sharks very rarely kill humans,Aperson has a greater chance of being struck by lightning or drowning in a bath than of being killed by a shark.Only 74 people have been reported killed by great whites in the last century.But great white sharks can reach six meters in length and weigh 2200 kilograms or more.With frightening jaws that can hold up to 3000 teeth arranged in several rows,they could very easily kill and eat a helpless human in the water.Why is it,then,that most people survive attacks by great whites? Shark researchers are trying to comprehend the reasons that allow people to escape without being eaten.
The most common explanation is that great whites don’t see well.It has been thought that they mistake people for the seals or sea lions which make up a large part of their diet.There is reason to doubt this,however.Recent information shows that great whites can actually see very well.Also,when accacking seals,great whites shoop up to the surface and bite with great force.When approaching humans,however,they most often move in slowly and bite less hard.They soon discover that humans are not a high-fat meal.” They spit us out because we’re too bony,” says Aidan Martin,director of Reef Quest Center for Shark Research.
Shark researchers like Martin hypothesize that great whites are actually curious animals that like to investigate things.It’s possible that they use their bite not only to kill and eat,but also to gather information,Although such an experience is unlucky for people like Craig Rogers,when sharks bite surfboards or other objects or people,they are likely just trying to learn what they are.
练习：
1.After Craig Rogers fell into the water,the shark C .
A) bit his surfboard B) bit his fingers
C) swam away D) attacked him
2.It is difficult for the author to understand why great whites A .
A) often let humans escape B) kill humans
C) have so many teeth D) grow to six meters or more
3.Which of the following is closest in meaning to make up in line 2 of paragraph 4? B
A) create B) are C) increase D) depend upon
4.The word their in line 2 of paragraph 4 means B .
A) people’s B) great whites’ C) sea lions’ D) seals’
5.What is the main idea of the forth paragraph? C
A) Great whites eat low-fat,bony meals more slowly.
B) Great whites see well enough to include seals,sea lions,and humans in their diet
C) We now know great whites don’t mistake humans for other animals.
D) There is reason to doubt that great whites see well enough to attack humans.
