Last year, our school offered optional courses for the students in Senior 2. At the beginning of a term, our teacher introduced several courses to us, included Music Appreciation, Advanced Math, Western Art, and etc. We selected the courses we were liked, filled in the forms, and handing them in. Several days late, the optional courses started. We went into different classroom to begin our study delightful. During the lessons, some of them enjoyed beautiful music, while others learned amazing knowledge in math. Everyone gained which they couldn’t get in the regular lessons. Thanks to the optional courses, we had the opportunities to learn what we were really interested.

In late April 2017, a violent storm swept through the southern United States, 1.(destroy) more than $ 1 billion in property and killing 35 people. But it was 2.wonder that a group of birds sensed the oncoming disaster and left long before the first clouds arrived. A year earlier, a science team had tagged golden-winged warblers (莺) with leg trackers 3.( study) their annual migrations to South America. Two days before the storms 4.(strike), five golden-winged warblers flied away, traveling south to the Florida coast.

It's the first time that the birds which normally migrate with the seasons 5.(observe) to fly away when a big storm hits. The researchers suspect this behavior occurs only when the threat of 6.(injure) outweighs the energy costs of a long trip. But nobody knows 7.the birds guessed the storm's harm and left so soon. 8.( puzzle) by it, the scientists initially reasoned that changes in weather—atmospheric pressure, temperature or wind speed—signaled the upcoming disaster. Yet when they checked weather records, none of these factors waved 9.(significant) before the storm. Instead, the team thinks that the approaching storms created a disorder of infra sounds, low-frequency sound waves, that birds can hear, 10.humans can't.

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.

D. They reflect animal migration seasons.

2.What is the purpose of writing Paragraph 3?

A. To summarize the research process.

B. To further support the research findings.

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.
