【正确答案】 D

【答案解析】[解析] 当伊丽莎白在这里时，生活从来不会乏味。句中dull：乏味的。happy：快乐的，如：I wish you a very happy future．我祝你有非常幸福的未来、difficult：困难的，如：So far as English is concerned, it is not so difficult as you might think．就英文而言，它并不像你所认为的那样难。exciting：令人兴奋的，如：We went to an exciting football game last week．我们上周看了场激动人心的足球比赛。boring：无聊的，如：It was boring to sit there without anything to do．无所事事地坐在那里太无聊了。只有boring意思上和dull最接近。
