【正确答案】 C

【答案解析】[听力原文] Your assignments this term will be to write two major research papers. One of the most important things about writing a research paper is giving proper credit of your resources of information. Failure to do this is called plagiarism which is a form of intellectual dishonesty. Plagiarism is a kind of stealing or at least an unauthorised borrowing of someone else's ideas. Sometimes inexperienced students will plagiarise unintentionally, and then be surprised when the teacher won't accept their papers, or gives them a failing grade. The best way to avoid an unintentional plagiarising is to be very careful in gathering your information. As you take notes on books and magazine articles about the topic you've selected, first try to assimilate the information thoroughly. Secondly, write it down in your own words. This is called paraphrasing. If you do a good job of paraphrasing, you'll capture the main idea from your source without actually using any phrases from it. Most of your notes should probably be paraphrases. However, occasionally you may find something you wish to quote directly in your research paper. In this case, be sure that you copy the quotation precisely in your notes and enclose it in quotation marks. That way when you're finalising your research paper, you'll be able to remember which of your notes are direct quotes and which are your own summaries of the material. You can then incorporate them appropriately and give the original author proper credit. What kind of assignment does the speaker discuss with the students? 本短文四道题选项中的research papers，materials，notes，quotations和be paraphrased表明，短文可能与写作某种类型的文章有关，涉及写作材料和方法。 选项均以v.-ing形式开头，且宾语各不相同表明，本题可能涉及短文主题或正在进行的动作。短文开头即提到“Your assignments this term will be to write two major research papers.”，故答案为C。短文的主题一般在开头部分，听音时要注意。

【正确答案】 B

【答案解析】[听力原文] What does the speaker warn the students not to do? 选项中的late，steal和non-relevant表明，本题可能考查不应该做的事情。短文开头部分提到写研究论文最重要的事情之一就是要giving proper credit of your resources of information(尊重信息的来源)，然后从反面介绍剽窃现象“Plagiarism is a kind of stealing...someone else's ideas.”。由此可知，说话者告诫学生写论文时不要剽窃别人的观点，故答案为B。

【正确答案】 D

【答案解析】[听力原文] According to the speaker, how should most of the notes be taken? 选项表明，本题可能考查方式方法。短文中提到“Secondly, write it down in your own words.”，故答案为D。短文脉络清晰，听音时听到表顺序的词(first，secondly...)时要特别留意。

【正确答案】 D

【答案解析】[听力原文] In the speaker's opinion, how should a direct quotation be used? 短文用however将话题转移到quotation的使用上，其中提到be sure that you...enclose it in quotation marks(确保应……将其标上引号)，D项表述与此一致，故为答案。听清问题中的a direct quotation，明确选项中it指代的内容是解答本题的关键。
