Entering the library, the freshman was ______ by the numerous books on shelves, as well as by the students who were studying quietly.A. expressedB. welcomedC. greetedD. disrupted

本题考查词汇辨析，解题思路是理解每个选项单词的含义，再结合句子语境来判断哪个选项最合适。

• A选项“expressed”：“express”常见含义为“表达”，“expressed”是其过去式和过去分词形式。在句子“Entering the library, the freshman was ____ by the numerous books on shelves, as well as by the students who were studying quietly.”中，“被书和安静学习的学生表达”不符合逻辑，所以A选项不正确。
• B选项“welcomed”：“welcome”意为“欢迎”，通常用于表达对某人的欢迎，比如“Welcome to our school.” 这里说新生被书和学生欢迎，不太符合正常表达习惯，所以B选项不合适。
• C选项“greeted”：“greet”有“映入眼帘；映入脑海；给人以……的印象”的意思。“be greeted by”表示“映入……的眼帘；被……所迎接”，在本句中，新生进入图书馆，书架上众多的书和安静学习的学生映入他的眼帘，符合语境，所以C选项正确。
• D选项“disrupted”：“disrupt”意为“扰乱；使中断”，“be disrupted by”表示“被……扰乱”。句子中并没有体现出新生被书和学生扰乱的意思，所以D选项不符合题意。
