假设你是李明，请你就本校图书馆的状况给校长写一封信，反映如下问题：
1. 图书馆内本专业藏书偏旧，不利于学生及时了解国内外新的学术发展。
2. 阅览室灯光太暗、没有空调设备。
3. 新开发的电子借阅系统有待完善--许多图书资料都无法使用该系统查到。
Dear President:
I'm Li Ming. I venture to write to you and unveil the existing problems of the library under your charge.
We exhaust our patience to look for items related to our major on shelves crammed with outdated shabby books. Most of them should be weeded. The newly published counterparts need to be purchased, displayed and circulated. The library armed with these fresh books enables us to track the newest information concerning scientific discoveries and scholarly accomplishment.
We all suffer the dim light and the absence of air conditioner in the reading room. This intolerably terrible scenario pressingly needs improving. The newly introduced library system is to be updated, for its search engine skips some valuable materials.
We are waiting for your response to these problems.
