TPO49听力答案及详细解析，供大家参考。
Conversation1
1.What are the speakers mainly discussing?
A.The student’s difficulties locating sources for a research project
B.The topic of the student’s research project
C.The student’s request to visit a particular part of the library
D.Procedures for requesting different editions of a book
答案：C
解析：
学生的第一句话“I need to get into special collections,in particular the british literature”，通过I need to表明意图是来看图书馆中关于英国文学的书籍。而之后的全文都在讨论学生没有教授的授权，是否能借阅这些书。所以答案选C。
2.Why is the student unable to use later editions or reproductions of a book he mentions?
A.The later editions contain errors.
B.Professor Gray specified the use of a particular edition.
C.The later editions must be requested from another library.
D.Reproductions typically omit the specific material he needs.
答案：D
解析：
通过工作人员的题问和学生的回答，我们能定位到这道题。考点即是师生之间的问答，而回答我们要重点记。 学生说他的project需要用到文献当中的注释，而这些注释并未在复制品中体现，都被clean up了(clean up相当于D选项中的omit忽视)。所以答案选D。
3.Why is the student reluctant to contact Professor Gray?
A.He already has disturbed her several times during her time away from campus.
B.He does not feel comfortable about asking her for another favor.
C.He does not know her e-mail address.
D.He wants to surprise her with a completed project.
答案：B
解析：
同上题一样，又是通过师生问答引出重要考点。学生说：我希望自已能搞定这件事而不是让教授帮我，因为之前的extra time已经是教授帮的一个大忙了。而现在我觉得skating on thin ice with her。这里的skate on thin ice with her的表达非常重要，我们一定要理解，正如我们中文所说的如履薄冰。试想一下，当教授已经帮了你一个忙而你却没做好的情况下，你再去请求她的第二次帮忙，这种时候是不是如履薄冰，胆战心惊，最好还是别去找她了，对不对?所以这个学生也是同样的心理，故答案选B(再求教授帮第二次忙，学生心里会不舒服)。
4.What does the woman imply about the rules regarding Special Collections?
A.The rules are unfair to the students.
B.The rules are in place to protect the books.
C.The rules are determined by the professors.
D.The rules have changed since the previous semester.
答案：B
解析：
Employee用这样的一句话“If we don't maintain our policies,they'll disintegrate”再次拒绝了学生，这里的policies(policy政策)等同于B选项中的rules规定。如果我们不维持我们的规定，这些文献都会损坏。所以这些规定就是用来保护这些文献书籍，故答案选B。
5.Replay: What does the woman mean when she says this:
A.She has been in a similar situation herself.
B.She will help the student solve his problem.
C.Shen has often heard this kind of story from students.
D.She thinks the student should try to understand her situation.
答案：C
解析：
Everybody has special circumstances.每个人都会有些特殊情况。言下之意即：你不用多讲了，你们这样的故事我听多了。所以答案选C。相信有些同学会有疑问为什么不选D?“每个人都有特殊情况，我们不可能每个人都网开一面，请理解我们”。有这类想法的同学，建议一定要收收脑洞，千万不要过于脑补，如果D是对的，重听原话应改变为“I understand, but sorry, we also have our special circumstance that the policy cannot be changed.” 所以同学们，在错误选项无法排除的情况下，可以尝试下反向思维，这样更有利于把握出题人的思路，增强选项辨析能力哦，加油。
