When scientists accidentally killed what turned out to be the world’s oldest living creature, it was bad enough. Now, their mistake has been worsened after further research found it was even older – at 507 years.
The ocean quahog, a type of deep-sea clam, was dredged (捕捞) alive from the bottom of the North Atlantic near Iceland in 2006 by researchers. They then put it in a fridge-freezer, as is normal practice, unaware of its age. It was only when it was taken to a laboratory that scientists from Bangor University studied it and concluded it was 400 years old.
The discovery made it into the Guinness Book of World Records. However, by this time, it was too late for Ming the Mollusc(软体动物), named after the Chinese dynasty when its life began. Unfortunately researchers who calculated Ming’s age killed it instantly by opening its shell.
The researchers opened the ancient clam up to judge its age by counting growth rings inside. But the rings were so close together that scientists ended up having to count the rings on the outside to be accurate, leading CBS journalists to point out that if scientists had just started there, Ming could have lived on. Now, after examining the quahog more closely, using more advanced methods, the researchers have found the animal was actually 100 years older than they first thought.
Dr Paul Butler, from the University’s School of Ocean Sciences, said: “We got it wrong the first time and maybe we were a bit hasty publishing our findings back then. But we are absolutely certain that we’ve got the right age now.” The mollusc was born in 1499 – just seven years after Columbus discovered America and before Henry VIII had even married his first wife, Catherine of Aragon in 1509.
A quahog’s shell grows by a layer every year, in the summer when the water is warmer and food is plentiful. It means that when its shell is cut in half, scientists can count the lines in a similar way that trees can be dated by rings in their trunks.
Jan Heinemeier, associate professor at the University of Denmark, who helped date Ming, told Science Nordic: “The fact that we got our hands on a 507-year-old animal is incredibly fascinating, but the really exciting thing is of course everything we can learn from studying the mollusk.”At first, the scientists found that _____________.

There was once a professor of medicine, who was very strict with the students. Whenever he took the chair on the exam committee(担任考试委员会主席), the students would be in fear, because he was seldom pleased with the answers they gave. A student would be lucky enough if he or she could receive a good mark from him. At the end of the term, the students of medicine would take their exam again. Now a student entered the exam room and got seated before the committee. This student was a little nervous as he knew it would not be so easy to get through the exam at all.
The professor began to ask. The student was required to describe a certain illness, his description of which turned out to be OK.
Then the professor asked about the cure (药剂) for illness, and the student, too, answered just as right.
“Good,” said the professor, “and how much will you give the patient?”
“A full spoon”, answered the student.
“Now you may go out and wait for what you can get.” said the professor. At the same time, the committee discussed carefully the answers the student had given. Suddenly the student noticed that there was something wrong with his last answer. “A full spoon is too much,” he thought to himself. Anxiously he opened the door of the room and cried, “Mr Professor, I’ve made a mistake! A full spoon is too much for a patient. He can take only five drops.”
“I’m sorry, sir.” said the professor coldly, “But it’s too late. Your patient has died.”The students were afraid of the professor because_________.
A.they often angered and disappointed him |
B.he often misunderstood them and give them bad markers |
C.their answers often astonished him |
D.their answers seldom satisfied him |
Before he left the room the student was almost sure that ______.
A.his last answer was satisfying |
B.he had passed the exam, and the only thing was to wait for the mark |
C.he had made a mistake |
D.he had not done well in the exam |
Which of the following is Not true?
A.The patient will be in danger if he’s taken as much as a full spoon. |
B.The doctor will be in trouble if he’s given the patient a full spoon. |
C.Since one spoon is less than five drops, the patient will be all right soon if he takes only one full spoon at a time. |
D.If the patient wants to remain safe, he should take no more than five drops at a time. |
When Joan gave birth to the first boy in her family in three generations, she and her husband were overjoyed. So were her parents. Joan expected her elder sister, Sally, to be just as delighted as them. Joan had always admired Sally--the beauty and the star of the family--and felt happy about her achievements.
But since the baby's arrival, the sisters have become distant. Joan feels hurt for Sally seems completely uninterested in her baby. Sally, who has no children, claims that her younger sister "acts as if no one ever had a baby before."
Neither Sally nor Joan understands that the real cause of the current coldness is that their family roles have suddenly changed to the opposite. Finally Joan seems to be better than her elder sister--and Sally doesn't like it! Their distance may be temporary, but it shows that childhood competition don't fade easily as ages grow. It can remain powerful in relationships throughout life.
In a study of the University of Cincinnati, 65 men and women between ages 25 and 93 were asked how they felt about their brothers and sisters. Nearly 75 percent admitted having hidden competitive feelings. In a few cases, these emotions were so strong as to have affected their entire lives.
Many adult brothers and sisters are close, supportive--yet still tend to compete. Two brothers I know turn into killers when on opposite sides of a tennis net. Off the court, they are the best of friends. My own younger sister can't wait to tell me when I've put on weight. However, she's a terrible cook and that pleases me; I tease her when she comes to dinner. Happily, despite these small failings, we have been an important resource for each other.
In between the very competitive and the generally supportive children lie those who say that no friendship should survive. Some brothers and sisters stay at arm's length, hut never give upcompetition completely. Why do these puzzling, unproductive, often painful relationships continue to exist?When Joan's son was born, Sally.
A.felt very happy | B.felt not delighted |
C.moved away | D.admired her a lot |
What happens to children's desire to compete with their brothers and sisters?
A.It sometimes will disappear when they grow up. |
B.It will never disappear throughout life. |
C.It will improve their relationships when they grow up. |
D.It will never harm their relationships when they grow up. |

B.Because she wants the author to stop calling her a bad cook. |
C.Because she wants to make fun of the author's weight. |
D.Because she wants to be honest with the author. |
The underlined sentence means that although some brothers and sisters.
A.live near each other, they still have competitions |
B.live away from each other, they stop their competitions |
C.live together, they often think of ending their competitions |
D.live within a big family, they often try to end their competitions |

The influence of America is increasing in my country. Spanish people drink Coca Cola, wear blue jeans, watch Hollywood movies, listen to American music, and eat fast food, and they do these things every day.
I think that American movies are a good way to spread American culture because people are often influenced by what they see in the movies. Most of the programs and documentaries (纪录片) we watch on TV are from America, and most of the movies we go to see are made in Hollywood.
In the last few years, the government has tried to protect the Spanish movies. Now, in our cinemas, at least twenty percent of the movies which are shown must be from Spain or from other countries in Europe.
American culture is a part of Spanish life now. It’s certain that many things from America are as much a part of people’s lives as Spanish things. For example, Coca Cola is as familiar to everybody as any typical Spanish product. I’ve known about Coca Cola for my whole life.
However, it’s different with Western fast food. For example, I don’t think McDonald’s is as successful in Spain as it is in other countries. In my opinion, one of the reasons may be the lifestyle of the Spanish people. The Spanish people normally eat at home.
On the other hand, maybe McDonald’s hamburgers will eventually replace the famous Spanish tapas. It’s true that in every city in Spain you can find a McDonald’s, and it is more popular among the Spanish children than among the adults. In any case, it’s obvious that American culture is becoming more and more a part of our lives every day.From the first paragraph we can know that ____.
A.the influence of America on Spain can be found everywhere |
B.most Spanish people don’t like to listen to their own music |
C.fast food spreads from Spain to the United States |
D.some Spanish actors go to America to improve their acting skills |
What plays an important part in the spreading of American culture in Spain?
A.American novels. | B.Hollywood movies. |
C.McDonald’s. | D.American music. |
Why did the government set some rules for the films shown in Spain?
A.To protect foreign culture in Spain. |
B.To earn more money from Spanish films. |
C.To limit the number of foreign movies. |
D.To unite the European Community. |
What do you think Spanish tapas might be?
A.The name of a drink. | B.The name of a restaurant. |
C.A clothing brand. | D.A certain kind of food. |
Sooner or later, most students are to take some form of English examinations. Often the more successful students are better prepared. However, sometimes students who do well have better test taking skills. These abilities really have nothing to do with understanding English better. They are skills that make taking the test easier, and therefore provide better results.
Here are some very important—and often ignored—guidelines to taking a test successfully.
Do not insist on completing each question before going to the next. This is extremely important. Remember one question may only be worth one point! You will become nervous when you fail to find out its answer, making you lose your concentration and leading to worse results. However, answering the questions you are sure you know results in your being more relaxed and feeling more confident.
Go through the test a second time working out the answers to more difficult questions. Sometimes questions asked are answered in later questions asking for different things.
Usually(but not always) a strong first impulse(冲动) means we know the answer and we don’t really have to think about it too much. Going back to think about it usually makes you unsure and often causes a mistake. This is very common, so be very careful!
If you don’t know the answer, write something. If you are answering a 4 possibility multiple choice question you will still have a 25% chance of being correct!
Taking a test is as much for you as is for your teacher, so never cheat. If you cheat, you don’t help yourself in the long run.In the first paragraph, the writer stresses the importance of ______.
A.better preparations for exams. |
B.better understanding of English. |
C.better skills at taking exams. |
D.better results of taking exams. |
When taking an exam, you are advised ______.
A.to first answer the questions which are easier to you. |
B.to depend on your first impulse to answer the questions. |
C.to search the test paper for all the answers to the questions. |
D.to give up the questions whose answers you don’t know. |
It is common that many students______.
A.pay much attention to their testing skills. |
B.often give up a difficult test halfway. |
C.often get higher results by cheating. |
D.don’t believe in their first impulse. |
What would be the best title of the passage?
A.Effective Studying Methods. |
B.Effective Test Taking Skills. |
C.Getting Better Exam Results. |
D.Being Successful Students. |
