3．Since many of you are planning to study at a college or university in this country，you may be curious to know what you usually do in a typical week，how you can get along with your fellow students，and so on．These are the questions I want to discuss with you today．
First，let's talk about what your weekly schedule will look like．No matter what your major may be，you can expect to spend between four and six hours a week for each class attending lectures．Lectures are usually in very large rooms because some courses such as introduction to sociology or economics often have as many as two or three hundred students，especially at large universities．In lectures，it's very important for you to take notes on what the professor says because the information in a lecture is often different from the information in your textbooks．Also，you can expect to have exam questions based on the lectures．So it isn't enough to just read your textbooks； you have to attend lectures as well．In a typical week you will also have a couple of hours of discussion for every class you take．The discussion section is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures，the reading，and the homework．In large universities，graduate students，called teaching assistants，usually direct discussion sections．
If your major is chemistry，or physics，or another science，you'll also have to spend several hours a week in the lab，or laboratory，doing experiments．This means that science majors spend more time in the classroom than non science majors do．On the other hand，people who major in subjects like literature or history usually have to read and write more than science majors do．

分析 本文为科教类文章，作者和读者讨论了大学生活中可能会遇到的问题．
解答 25---28 ADAD
25．答案A．主旨大意题．根据第一段These are the questions I want to discuss with you today可知，作者要和读者讨论大学生活中可能会遇到的问题．故选A．
26．答案D．细节理解题．根据第二段So it isn't enough to just read your textbooks； you have to attend lectures as well可知，你的教材是远远不够的，你还需要参加讲座．故知教授要求的远远多于课本．故选D．
27．答案A．细节理解题．根据第二段The discussion section is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures，the reading，and the homework．In large universities，graduate students，called teaching assistants，usually direct discussion sections可知，你可以在讨论组里提关于讲座、阅读材料、作业等的问题，在有的大学会有高年级的学生指导．故A选项错误．
28．答案D．细节理解题．根据最后一段On the other hand，people who major in subjects like literature or history usually have to read and write more than science majors do可知，相对科学专业而言，文学或历史专业的学生要读得更多，写得更多．故D选项正确．
点评 做题技巧：一、抓住文章的首段与末段及段落的首句和末句．文章的首段与末段、段落的首句和末句，一般表达文章的主题和段落的中心思想，其它段落及句子只起补充、说明、解释或引申的作用．二、进行合理推断．答题时，要领会句子之间的逻辑关系，特别是相邻句子之间的关系，这样有利于理解全文．表示逻辑关系的标志词是连接词、副词、代词、介词短语、关系词、插入语等，通读时应特别注意．三、猜测推敲生词．阅读短文时，常常会遇到一些生词．首先要把整段、整篇文章看完．通过对全篇短文的理解，就很有可能猜测出生词的大意．四、利用常识．解题多了解一些常识性知识有利于阅读理解．五、正确理解题干．纵观历年高考试题，阅读理解试题一般有以下几种题型：一是直接回答who，whom，which，what，where，when，why，how等疑问词引起的细节问题；二是猜测词义题；三是推理判断题；四是综合概括题．在做阅读理解题时，一定要仔细看完、看清楚试题要求再作答，特别要注意NOT，TRUE，EXCEPT等词．有时，要先看题后阅读文章，带着问题去读短文，可缩短阅读时间，效果也许会更好．
