Learn to Cite Sources (引用资料)
During your university education, you’ll be exposed to ideas and scientific theories of scholars and scientists. Unavoidably, your own ideas will be shaped by the ideas you come across. 1. That means you should go beyond what you learn in your textbooks or in the library. Your original work is the basis for your professor’s evaluation of your performance. Thus, academic honesty is fundamental in your university education. It demands that you cite the source materials you base your own work on. 2.
Correctly citing your sources helps you distinguish your own ideas from those of other scholars. On the readers’ side, it permits a reader to determine the depth of your research. 3. On the contrary, lack of citing will only raise your reader’s doubt.
So you need to learn when to cite and how to provide an adequate or accurate reference list. If you fail to cite your sources, whether deliberately or carelessly, you will be found responsible for plagiarism (抄袭) . 4. If you are not sure, ask your professor for guidance before submitting the paper or report. Keep in mind this general rule: when in doubt, cite!
5. For example, students from East Asia may think that copying directly from sources is the proper way to do research. Students in France, preparing for the final examination, may be encouraged to memorize whole passages and copy them into papers. Those cultural differences can lead to false assumptions about academic expectations in the country you study in.
A. Some university students may cheat in different ways.
B. These include other scholars’ ideas, figures, graphs and so on.
C. The academic challenge you face is to make something original.
D. Often, students want to use others’ opinions to support their own essays.
E. It also allows a reader to appreciate your original contribution to the research.
F. For international students, it is important to know local academic expectations.
G. Not knowing academic regulations is an unacceptable excuse for such behavior.
An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in the natural world. Their online species searches follow the patterns of seasonal animal migrations (迁徙).
Migratory birds (候鸟) flood back to where they reproduce every spring. That migratory behavior is accompanied by some human behavior. “In English-language Wikipedia (维基百科), the online searches for migratory species tend to increase in spring when those birds arrive in the United States,” said the lead author John Mittermeier.
And not just birds. Mittermeier and his team surveyed nearly 2.5 billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.
This finding suggests new ways to monitor changes in the world’s biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation.
Mittermeier is encouraged by the search results. He commented, “I think there’s a concern among conservationists (生态环境保护者) that people are losing touch with the natural world and that they’re not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people’s Wikipedia interest closely related to changes in nature.”
Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, “By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help.”
1.What have researchers found about species searches?
A. They strengthen ties among people.
B. They affect the animal movements.
C. They differ in language backgrounds.
D. They reflect animal migration seasons.
2.What is the purpose of writing Paragraph 3?
A. To summarize the research process.

C. To show the variety of species searches.
D. To present researchers’ heavy work load.
3.How does Mittermeier feel about the search results?
A. Satisfied with Wikipedia’s service.
B. Worried about Wikipedia behavior.
C. Amazed at people’s care about nature.
D. Sad about people’s not getting close to nature.
4.Why does Richard think such search data is useful?
A. It helps to aim at conservation targets.
B. It increases interest in big data approaches.
C. It keeps track of trends in biologists’work.
D. It pushes people to solve difficult problems.
It’s 3 o’clock and you’ve been hard at work. As you sit at your desk, a strong desire for chocolate overcomes you. You try to busy yourself to make it go away. But it doesn’t. Here is another situation. Perhaps you are not feeling well. The only thing you want to eat is a big bowl of chicken soup, like your mum used to make when you were sick as a child. Food cravings are a strong desire for a specific type of food. And they are normal.
Scientists at the website How Stuff Works compare hunger and cravings (渴望) this way. Hunger is a fairly simple connection between the stomach and the brain. They even call it simply “stomach hunger”. When our stomachs burn up all of the food we have eaten, a hormone (激素) sends a message to one part of the brain for more food, which regulates our most basic body functions such as thirst, hunger and sleep. The brain then produces a chemical to start the appetite and you eat. Hunger is a function of survival.
A craving is more complex. It activates brain areas related to emotion, memory and reward. These are the same areas of the brain activated during drug-craving studies. Because of this, some scientists call food cravings “mind hunger”. People often crave foods that are high in fat and sugar. Foods that are high in fat or high in sugar produce chemicals in the brain. These chemicals give us feelings of pleasure.
In a 2016 study, researchers at Cambridge University found that dieting or restricted eating generally increases the possibility of food cravings. So, the more you deny yourself a food that you want, the more you may crave it. However, fasting (禁食) is a bit different. They found that eating no food at all for a short period of time lessened food cravings.
So, the next time you crave something very specific, know that your brain may be more to blame than your stomach.
1.Which of the following statements is NOT true when “stomach hunger” appears?
A.The part of brain which regulates some functions of our body works.
B.A chemical is produced by the stomach to start the appetite.
C.All the food we have eaten has been exhausted.
D.A hormone delivers a message to the brain for food.
2.What do we learn about food cravings?
A.It means the stomach functions well.
B.It ensures a person survives hunger.
C.It shows food is linked to feelings.
D.It proves the brain decides your appetite.
3.What’s the likely result of dieting?
A.The increase of food desire. B.The decrease of chemicals.
C.The refusal of fat and sugar. D.The disappearance of appetite.
4.What is the best title of this passage?
A.Dieting: It Makes You Crave More
B.Fasting: It Lessens Food Cravings
C.Food Cravings: They are All in Your Brain
D.Hunger: It is a Function of Survival
Buster used to be a lovely dog playing and running on a farm all day before his handler (训练员). His life had a big change after Will’s presence because Will found he did extremely well in sniffing tests. Will thought Buster had a special talent and decided to let him become a member of RAF police working dogs. Buster began working with Flt Sgt Barrow in 2007, and the pair was sent to Afghanistan’s deadly Helmand province. There, Buster saved countless lives by sniffing out explosive devices (IEDs), as well as weapons. He joined his comrades repeatedly on foot patrols hunting Taliban terrorists and tracking down bombs. He also acted as a useful diplomatic tool, due to his friendly approach to local children. The RAF soon had a long train of children in tow, as Buster drew in his crowd and entertained them.
After his glittering service with the RAF, Buster retired in 2011, and died in 2015 at the age of 13 at the home of his handler, in Lincolnshire where he had been enjoying retirement with his handler Will, his wife Tracy and their two dogs who will inherit their father’s career.
Over the course of his career, Buster is thought to have saved more than 1,000 lives. He also helped patrol British bases and searched vehicles at check points, and upon retirement was made the official RAF Police mascot (吉祥物). Buster’s brave exploits were even documented in Flt Sgt Barrow’s book, which was published in January and soon became a best-selling one.
Buster completed five tours of duty in Afghanistan, Bosnia and Iraq and earned a row of campaign medals, and it was because of his great efforts in these austere environments full of terrorism that he would be remembered. It was the saving of countless lives by searching out IEDs that saw the honor of official lifetime mascot of the RAF Police bestowed（授予）upon Buster. The RAF police are now planning to honor Buster as part of a special event to celebrate RAF Police Working Dogs.
1.What made a big difference in Buster’s life?
A.He took a sniffing test.
B.Will found his special ability.
C.He was chosen to work for RAF.
D.Will decided to train him.
2.What can be inferred from the passage?
A.Buster was born at Will Barrow’s home in Lincolnshire.
B.Buster’s children will also be a member of RAF police working dogs.
C.Buster was bestowed the mascot during working in Afghanistan.
D.Buster’s death in a campaign is a great loss for the RAF Police.
3.The underlined word “austere” in the last paragraph probably means “_________”.
A.severe B.respectable
C.mild D.hopeless
4.The passage mainly talks about__________.
A.a heroic sniffer dog’s legendary life
