Looking back on my childhood, I am convinced that naturalists are born and not made. Although we were brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental math.
Before World War I we spent out summer holidays in Hungary. I have only the dim(模糊的)memory of the house we lived in, of my room and my toys, Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of dogs, the farm animals, the local birds and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into various investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries.Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle. Because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some may light honor, with the title of scientific research.
But curiosity, a keen eye ,a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities required is self-discipline, a quality I lack, A scientist can be made a naturalist. If you can combine the two, you get the best of both worlds.According to the author, a born naturalist should first of all be
A.full of ambition | B.self-disciplined | C.full of enthusiasm | D.knowledgeable |
The first paragraph tells us that the author
A.lost his hearing when he was a child |
B.didn’t like his brothers and sisters |

The author says that his a naturalist rather than a scientist probably because he thinks he
A.just reads about other people’s observations and discoveries |
B.lacks some of the qualities required of scientist |
C.has a great deal of trouble doing mental arithmetic |
D.comes up with solutions in most natural ways. |
The author can’t remember his clearly because
A.He didn’t live very long with them |
B.He was too young when he lived with them |
C.The family was extremely large |
D.He was fully occupied with observing nature |
Which of the following statements is true?

B.The author read a lot of books about the natural world and oil industry |
C.The author’s brothers and sisters were good at music and languages |
D.The author spent a lot of time working on riddles. |
We know that sugary sodas aren’t good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse.
Americans drink far more sodas than people in other countries— as much as 170 liters per person per year. But the impact of this study isn’t limited to the United States. “Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well,” study author Dr Honglei Chen said in a statement.
The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had.
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch(鸡尾酒), had a 38 percent higher risk than people who didn’t drink sweetened drinks. And all that extra sugar isn’t the actual problem. Researchers say that the artificial sweetener aspartame may be to blame.
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results “are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes.”
But there’s a bright side for those who can’t live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn’t drink any coffee, according to the study. “Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said Chen.What has the new study of more than 260,000 people found?
A.Sugary sodas aren’t good for the physical health of old people. |
B.Americans have a special tooth for sweet foods. |
C.Sweetened soft-drinks may increase the risk of depression. |
D.Sweetened soft-drinks have important physical consequences. |
What do we know about the process of the study?
A.About twenty-six thousand people participated in it. |
B.The oldest participants were below 80 when the study was over. |
C.Most of the participants had depression when the study was over. |
D.The study lasted more than ten years from the beginning to the end. |
It is implied in the passage that ______.
A.more research is needed to confirm the new findings |
B.the new findings aren’t consistent with any previous findings |
C.cutting one’s sodas intake will surely reduce one’s depression |
D.the new findings won’t have an impact on people’s drinking habits |
What should you drink in order to reduce the risk of depression?
A.Sodas. | B.Unsweetened coffee. |
C.Sugary coffee. | D.Fruit punch. |
Like any good mother, when Karen found out that another baby was on the way, she did what she could to help her three-year-old son, Michael, prepare for a new sibling. They find out that the new baby is going to be a girl, and day after day, night after night, Michael sings to his sister in Mommy's tummy.
The pregnancy progresses normally for Karen. But complications arise during delivery. Finally, Michael's little sister is born. But she is in serious condition. With siren howling in the night, the ambulance rushes the infant to the intensive care unit at St. Mary's Hospital.
The little girl gets worse. The doctor tells the parents, "There is very little hope. Be prepared for the worst." Karen and her husband have fixed up a special room in their home for the new baby — now they plan a funeral.
Michael, keeps begging his parents to let him see his sister, "I want to sing to her," he says. But kids are never allowed in Intensive Care. However, Karen makes up her mind. She will take Michael whether they like it or not.“If he doesn't see his sister now, he may never see her alive.” She dresses him in an oversized scrub suit and marches him into ICU. The head nurse recognizes him as a child and bellows, "Get that kid out of here now! " The mother, the usually mild-mannered lady glares steel-eyed into the head nurse's face, her lips a firm line. "He is not leaving until he sings to his sister!" Karen tows Michael to his sister's bedside. He gazes at the tiny infant losing the battle to live. And he begins to sing.
"You are my sunshine, my only sunshine, you make me happy when skies are gray”
Instantly the baby girl responds. The pulse rate becomes calm and steady.
"You never know, dear, how much I love you. Please don't take my sunshine away "
The ragged, strained breathing becomes as smooth as a kitten's purr.
Keep on singing, Michael. Tears conquer the face of the bossy head nurse as well as Karen.
Funeral plans are scrapped. The next, day — the very next day — the little girl is well enough to go home!

How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question,as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的)tests,for everything from baldness to breast cancer,and the list is growing.Question is do you really want to know what might eventually kill you? For instance,Nobel Prize-winning scientist James Watson,one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’(老年痴呆症).
“If I tell you that you have an increased risk of getting a terrible disease,that could weigh on your mind and make you anxious,through which you see the rest of your 1ife as you wait for that disease to hit you.It could really mess you up.”Said Dr.Robert Green,a Harvard geneticist.
“Every ache and pain,”Smith suggested,could be understood as“the beginning of the e nd.”“That’s right.If you ever worried you were at risk for Alzheimer's disease,then every time you can’t find your car in the parking lot,you think the disease has started.”
Dr.Green has been thinking about this issue for years.He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s.It was thought that people who got bad news would,for lack of a better medical term,freak out.But Green and his team found that there was “no significant difference”between how people handled good news and possibly the worst news of their lives.In fact,most people think they can handle it.People who ask for the information usually can handle the information,good or bad,said Green.The first paragraph is meant to _________________.
A.ask some questions | B.introduce the topic |
C.satisfy readers,curiosity | D.describe an academic fact |
Which of the following is true of James Watson?
A.He is strongly in favor of the present genetic tests. |
B.He is more likely to suffer from Alzheimer's disease. |
C.He believes genetic mapping can help cure any disease. |
D.He doesn’t want to know his chance of getting a disease. |
According to Paragraphs 3 and 4,if a person is at a higher genetic risk,it is ____________.
A.advisable not to let him know |
B.impossible to hide his disease |
C.better to inform him immediately |
D.necessary to remove his anxiety |
The underlined part“freak out”in Paragraph 5 is closest in meaning to _____________.
A.break down | B.drop out |
C.leave off | D.turn away |
The study led by Dr.Green indicates that people ________________.
A.prefer to hear good news |
B.tend to find out the truth |
C.can accept some bad news |
D.have the right to be informed |
Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects.The software could eventually allow smart phone-armed soldiers to target the location of their enemies.On the home front,the software could be used by everyone,including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it.
“The great advantage of a Smartphone is that it provides so many tools in a single,readily available,relatively inexpensive package,”said Qia Wang,a doctoral student who led the development of the software.“For example,on the battlefield,a soldier needs a rangefinder,compass,GPS and other tools to get information before calling in an air strike.With our software,the soldier can have all those instruments in one device that can be purchased off the shelf.When that soldier returns from War,she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video.”
Wang and his colleagues developed their software to locate and track:
Targets of known size—when the size of the target is known.a single image is enough to pinpoint the target’s location.
Targets of unknown size—If the exact size of a target is unknown,the software uses two images to triangulate the location of the target·
Moving targets—By taking a short video of a moving target,the smartphone software can calculate how fast the target is moving and in what direction it is going.
“Currently,our software is limited by the physical abilities of smartphone hardware,but the devices are improving rapidly,”Wang said.“We expect that improvements in GPS accuracy,battery life and camera resolution will allow our software to make even more accurate observations.”.From Paragraph 1 we can know that the new software can_______.
A.determine the speed of moving objects |
B.1ocate objects in the distance exactly |
C.defend soldiers against their enemies |
D.help biologists protect rare animal |
.The example given by Qia Wang is meant to ________________.
A.make an advertisement |
B.describe the software briefly |
C.show the benefits of the software |
D.present the functions of smartphones |
.How does the software calculate the speed of a moving object?
A.By taking a short video. | B.By locating its position. |
C.By taking a single image. | D.By measuring real-life size. |
.What’s Qia Wang’s attitude towards the future of the software?
A.Casual. | B.Optimistic. |
C.Cautious. | D.Flexible |
.What is the best title of the text?
A.Qia Wang,a Talented Doctoral Student |
B.Use Smartphones to Their Full Potential |
C.Targeting and Tracking With Smartphones |
D.Smartphone-armed Soldiers on the Battlefield |
Many years ago,a French naturalist,the Count de Buffon,wrote some books about natural history.The books were a great success even though some critics did not like them.Some critics said,“Count Buffon is more of a poet than a scientist.”
Thomas Jefferson did not like what the Count had said about the natural wonders of the New World.It seemed to Jefferson that the Count had spoken of natural wonders in America as if they were unimportant.
This troubled Thomas Jefferson.He too was a naturalist,as well as a farmer,inventor,historian,writer and politician.He had seen the natural wonders of Europe.To him,they were no more important than those of the New World.
In 1788,Thomas Jefferson wrote about his home state,Virginia.While writing,he thought of its natural beauty and then of the words of the Count de Buffon.At that moment.Jefferson created a new word—belittle.He said.“The Count de Buffon believes that nature belittles her productions on this side of the Atlantic.”
Noah Webster,the American word expert,liked this word.He put it in this English language dictionary in 1806,“Belittle—to make small,unimportant.”
Americans had already accepted Jefferson’s word and started to use it.In 1797,the Independent Chronicle newspaper used the word to describe a politician the paper supported.“He is an honorable man,”the paper wrote,“so let the opposition try to belittle him as much as they please.”
In 1872,a famous American word expert decided that the time had come to kill this word.He said,“Belittle has no chance of becoming English.And as more critical writers of America,like those of Britain,feel no need of it,the sooner it is forgotten,the better.”
This expert failed to kill the word.Today.belittle is used where the English language is spoken.Why did Thomas Jefferson disagree with the Count de Buffon?
A.The Count said something silly about the Atlantic. |
B.The Count wasn’t a true scientist in natural history. |
C.The Count was a poet from a different country. |
D.The Count belittled the natural wonders in America. |
We can infer that Jefferson created the word“belittle”out of his ___________.
A.anger | B.excitement |

From the text we can know that ______________.
A.all critics thought little of the Count de Buffon |
B.Europe has better wonders than the New World |
C.the word“belittle”survived from disagreements |
D.word experts can change the future of a new word |
Which of the following is true of the word“belittle”?

B.It was invented by the Count de Buffon. |
C.It was used to describe nature. |
D.The Independent Chronicle made it popular. |
What is the main idea of the text?
A.How the word“belittle”came into being. |
