选B
1.因为must除了有“必须”的意思外,还可以表示猜测.
she must be in the reading room.她应该在阅览室里.（表推测,因为后问题到她喜欢阅读,作为推测的根据.）
2.而其他3项与题目意思不符
“can”也可表示推测,但仅用于否定句中,表示“不可能”.eg：She can't be in the reading room because she doesn't like reading.
“need”意为需要做某事；“Have to”意为必须做某事,与题意不符

B 表肯定，因为他非常喜欢读书，所以应该是肯定地猜测她在读书室。

B

must She likes reading very much.可以肯定她必定在阅览室里
must 在所有的情态动词里语气最强

B 。must表示非常肯定的推测和判断

B
对对方很了解 MUST BE 表肯定！

Bmust

B肯定性推测。因为后边肯定了she likes reading very much.A、C、D连语法都不对。
