【点睛】文章主题和中心思想的阐述往往需要大量细节信息的支持，这些细节对于理解全文内容至关重要，同时也是归纳和概括文章中心思想的基础。命题人往往会要求考生根据不同的要求阅读文章，以获得某些特定的信息，或准确地寻求所需的细节，并对细节进行直接或间接辨认和理解。文章细节的理解可以细化为：（1）一一对应型。（2）语言转述型。（3）语意理解型。（4）是非辨别型。（5）事实排序型。
此题中的三题全为细节理解题。细节理解题首先要根据题干准确定位信息句，其次要对信息句进行准确的理解和判断，如第一题为转述型，1 hour and30 minutes，即90分钟。第二题和第三题则为简单的一一对应型，只要找到信息句即可得出答案。
