解答 Although all the students seem very happily at our school，but the buildings would be more beautiful if the school could∧decorated．We students thought the school looks like a desert and the concrete walls like the grey sky in a rainy day．We would be much happier and be able to study better if there are the number of posters，photos and paintings on the wall，that could certainly broaden our horizons and enrich our lives．Original art work are too expensive，but unless we buy art posters，the cost will be low．Using only a little money，it can make our school a nicer place．
详解：
1．happily改为happy；考查形容词，此处用形容词形式作seem的表语．
2．去掉but；考查连词，although引导让步状语从句时不能与but连用，故把but去掉．
3．decorate前面加be；考查动词的语态，the school与动词decorate之间是动宾关系，故在情态动词could后面加be构成被动语态．
4．thought改为think；考查动词的时态，考查动词的时态，本文用一般现在时陈述一个事实，故此处要用think．
5．in改为on；考查介词，具体到在某一天要用介词on．
6．the改为a；考查冠词，the number of 意为"…的数量"，a number of 意为"许多，大量的"，分析句意可知此处要用a number of．
7．that改为which；考查关系代词，这是一个非限制性定语从句，关系代词which指代上一句提到的posters，photos and paintings．
8．work改为works；考查主谓一致，work表示文学家、艺术家、音乐家等的"作品""著作"等时是可数名词，后面动词是are，故主语用复数形式works．
9．unless改为if；考查连词，分析句意可知此处用if引导一个条件状语从句，表示"如果…"．
10．it改为we；考查人称代词，本文以第一人称we（students）进行叙述，故此处主语也要用we．
点评 短文改错时要注意句子中人称和数是否一致，时态是否一致．各种词性之间的区别以及一些常用句型，固定短语的应用．这类题型一般考查的是基础知识，平时应注重积累，熟记一些句型及习惯常用结构．
