Zones
The library is divided into different zones. The upper floor is a quiet zone with over a thousand places for silent reading, and places where you can sit and work with your own computer. The reading places consist mostly of tables and chairs. The ground floor is the zone where you can talk. Here you can find sofas and armchairs for group work.
Computers
You can use your own computer to connect to the wi-fi specially prepared for notebook computers; you can also use library computers, which contain the most commonly used applications, such as Microsoft Office. They are situated in the area known as the Experimental Field on the ground floor.
Group-study places
If you want to discuss freely without disturbing others, you can book a study room or sit at a table on the ground floor. Some study rooms are for 2～3 people and others can hold up to 6～8 people. All rooms are marked on the library maps.
There are 40 group-study rooms that must be booked via the website. To book, you need an active University account and a valid University card. You can use a room three hours per day, nine hours at most per week.

A 篇：【21 题】细节理解题。题干中的 the upper floor 是有关地方的信息，这暗示我们可以在 Zones(地带)这个段落里面去找。根据 Zones 中 The upper floor is a quiet zone with over a thousand places for silent reading 可知，上层是供阅读的地方，答案为A。
【22 题】细节理解题。题干中的 group-study 告诉读者答案应该出现在 Group-study Places 中。A 错在 must，因为也可以是 2-3 people；B 错在 minimum(至少)，文中用了 You can use a room three hours per day…；D 错在不是applicants 标注出来，而是这样的房间已经标注好了（All rooms are marked on the library maps）。故选 C。
【23 题】细节理解题。题干中的 locker 出现在 Storage of Study Material 中，这里A、B、C、D 中出现文中所提到信息有 A 和 D，但和文中这句“When you have obtained at least 40
credits, you may rent a locker…”相匹配的只有D。故选 D。
