For example, we can buy presents for our parents as birthday presents, and we can also try our best to help the homeless children. As teenagers, we must make good use of it.。

古代风水学家讲究山川形势，他们把山称为“龙”，观察山脉的走向、起伏，寻找聚气之势；他们也喻河流为“龙”，追寻水的源头和流向，由此产生出“来龙去脉”之说。

后来这一成语逐渐引用到其他方面。

3.C有一个曾任过司空官职的人名叫李绅，因仰慕刘禹锡的闻名，邀请他饮酒，并请了几个歌妓来在席上作陪。

在饮酒间，刘禹锡一时诗兴大发，便做了这样的一首诗：“高髻云鬓新样妆，春风一曲杜韦娘，司空见惯浑闲事，断尽苏州刺史肠。

”“司空见惯”这句成语，就是从刘禹锡这首诗中得来的。

这首诗中所用的司空两个字，是唐代一种官职的名称，相等于清代的尚书。

从刘禹锡的诗来看，整句成语的意思，就是指李司空对这样的事情，已经见惯，不觉得奇怪了。

4. C”理解为天气转凉。

5. A三国蜀汉时期，成都是中国的织锦中心，美丽的蜀锦畅销全国，成为朝廷重要的贡赋来源。

朝廷专门设置了锦官管理，并在城西南筑锦官城，于是成都又被称为“锦官城”、“锦城”。

6. B东汉末年，刘备三顾茅庐请出诸葛亮并拜为军师7. B东晋太尉郗鉴要为自己女儿找女婿，就派一位门客到时任丞相的王导家选女婿。

门客回来说：“王家的年轻人都很好，但是听到有人去选女婿，都拘谨起来，只有一位在东边床上敞开衣襟，好像没有听到似的。

”郗鉴说：“这正是一位好女婿。

”这个人就是王羲之。

于是把女儿嫁给他。

“东床快婿”原本指王羲之。

本典出自《世说新语》8. D礼：礼节（即今德育）乐：音乐射：射箭技术（锻链体格，品格修养）御：驾驭马车的技术书：书法（书写，识字，文字）数：算法（计数）9. A此联为明东林党领袖顾宪成所撰（《名联谈趣》275）。
