But during all this, did the weight of the glass change?" asked the teacher."No." the students said."Then what caused the arm ache and the muscle (肌肉) stress?"The students fell silent for a moment."Put the glass down!" said one of the students."Exactly!" said the teacher. "The problems of life are something like this. Hold them for a few minutes in your head, and it seems OK. Think of them for a long time and they begin to make you ache. Hold them even longer and you will not be able to do anything. It's important to think of the challenges(挑战) in your life, but it' s even more important to put them down at the end of every day before you go to sleep. That way, you are not stressed.

Another person might see different colours while listening to music. Some people also taste colours. To one person, beef might taste blue and to another, yellow. Some people experience feelings in colour. For example, one person with synesthesia reports feeling pain as the colour orange.Another form of synesthesia is to experience sounds or tastes as shapes. Some people see music as squares and circles. Some people taste a sweet as a smooth ball. There are other forms of synesthesia, as well. For one man, different words have different tastes. Some words taste like pork; others taste like potatoes or eggs.Synesthesia is not a common condition. Perhaps only one person in every 5,000 has it.

②地处我国玉米主产区，土壤肥沃，适合玉米生长。
③位于平原地区，地势平坦，便于机械化耕作。
不利条件：①纬度较高，热量相对不足，玉米生长周期可能较长。
②冬季寒冷，可能会对土地进行冻害，影响来年玉米种植。
（2）①高光效种植模式间距扩大，使玉米植株间的空气流通性更好，有利于二氧化碳的补充，提高光合作用效率。
②垄向改为南偏西，能更好地接收阳光照射，增加了玉米植株的光照时间和强度，促进光合作用。
（3）①机械化生产效率高，能在短时间内完成大量玉米的种植和采收，保证玉米的新鲜度和品质。
②机械化生产可以降低人工成本，从而使玉米价格更具竞争力。
18.（1）①冬季，古尔班通古特沙漠地面辐射冷却强烈，近地面空气温度迅速下降。
②由于冷空气较重，在重力作用下下沉，形成逆温层。
③沙漠上空的暖空气较轻，不易下沉，维持了逆温层的存在。
（2）原因：①沙丘顶部海拔较高，水分蒸发快，土壤水分含量低，适合根系发达的白梭梭生长，以吸收更深层的水分。
②沙丘底部（坡脚）海拔较低，水分蒸发慢，土壤水分含量相对较高，适合一年生草本植物生长。
分异规律：这种现象属于垂直分异规律。
（3）①灌丛可以阻挡风沙，减少对其下植物的侵蚀和破坏。
②灌丛可以截留水分，增加其下植物可利用的水分。
③灌丛可以调节局部温度，为其下植物提供适宜的生长环境。
19.（1）①新西兰北岛山脉的形成影响了河流的分布，山脉成为河流的分水岭，使河流分布在山脉两侧。

2024-2025学年湖南省长沙市雅礼中学高三上学期月考（二）历史试题1. 陕西神木石峁遗址是龙山文化晚期重要遗址，考古发掘证实了其城址由皇城台、内城和规模宏大的外城等三重城垣构成，并出土了成排房屋建筑基址，高等级贵族墓葬群以及数以万计的玉器、陶器等。

这反映出当时（）A．统治秩序的变动B．思想文化的碰撞C．礼乐制度的崩溃D．新兴阶层的壮大3. 有学者指出：“东汉初期既然在洛阳立高庙，合祭西汉五帝，作为刘氏后裔，将世祖及以后历代皇帝神主纳于高庙中序昭穆、享祭祀，属于合乎情理的举措。
但汉明帝为光武帝单独立世祖庙，随后诸帝又皆立神主于世祖庙，却似乎隐隐含有与西汉帝系截然有别的蕴意，此举被后世视为违礼之举而加以掊击。
”这表明（）A．宗法观念已被摒弃B．儒学影响政治伦理C．皇权传承缺乏规范D．祖先崇拜源远流长4. 唐开元年间，关中农业的收成非常好。
于是，开元二十五年（737）敕曰：“宜令户部郎中郑防，殿中侍御史郑章，于京畿据时价外，每斗加三两钱，和籴粟三四百万石，所在贮掌。
江淮漕运，固甚烦劳，务在安人，宜令休息。
其江淮间今年所运租停。
”据此可知，唐朝（）A．漕运贸易退出历史舞台B．政府对物资流通进行理性干预C．经济重心南移趋势显现D．官民交易具有强制和掠夺色彩5. 如表为文献中有关宋代史事的部分记载。
据此可以得出的合理推论是，宋代（）C．注重利用经济手段加强边地治理D．逐渐掌控了民族交往交流的主动权6. 明代万历年间，土司刘瀚将养牛圈场迁于永兴场（湖南湘西），并新建石街道。
