三权分立与制衡的学说，该学说成为西方国家的主要政治原则。摘编自苏艾《启蒙运动在英国最早兴起的原因及影响財料三启蒙的目的是要实现人的自由发展，而启蒙的途径又只能是自由，所可以在一切事情上有公开运用自己理性的自由。因此，无论是从价值论x是工具论的意必上看，启蒙都是要紧紧地抓住人的自由这一根柢的。然而，当启蒙播到中国的时候，它却逐渐偏离了本义，发生了很大的变异。因为在中国半殖民地密半封建的社会中，摆脱落后挨打的命运才是第一位的，至于启蒙也是为了激发人们:的国家意识和个体意识，个人要为实现国家富强的目的服务，所以中国的启蒙事业就本末细，连走了交向，只有急动近利和工其主义的特红.正是这些因水，大同决定了启蒙在近代中国所遭遇的坎坷命运。2【技一摘编自胡应泉（启蒙的困境—启蒙在近代中国的命运简折》(1)根据材料一并结合所学知识，简述孟德斯鸠：三权分立与制衡”学说提出的背景了封和意义。(13分)中①李东丰出版《6的少，起？为汉思刘其®注坎大到准拉起出华出手丸北®的指治享众电关子所久月影西收为4子汉⑤戈炎又的的,林片()义量麻(制线四发听力立承试0找老月分收制起好吐历史（三）第5页（共8页）【24·D·历史一QG历史(

(I)由图一可知，寒冷刺激导致BAT细胞大量产热的调节方式属于调节。在寒冷环境中，皮肤的感受寒冷刺激，将兴奋传至(神经中枢)，最终增加甲状腺激素的分泌量，通过增加从而增加产热。同时，机体也会使皮肤血管以减少散热。(2)激素②通过运输到甲状腺，该过程是」(定向不定向)运输。人如果长时间缺碘，会引起大脖子病，原因是：缺碘引起甲状腺激素合成和分泌减少，对下丘脑和垂体的作用会减弱，相关激素含量会增加，其中，激素促进甲状腺腺体的发育，因此患大脖子病。下丘脑、垂体及甲状腺病变均可导致甲状腺激素含量偏低，形成甲减。现探究甲减的原因，患者①含量偏高、②含量偏低，推测其最可能是发生了病变。(3)去甲肾上腺素与BAT细胞膜上的受体蛋白结合后，引起细胞内产生第二信使cAMP,最终促进细胞中脂肪分解产生热量，可见去甲肾上腺素与甲状腺激素具有作用。除此之外，肾上腺素也具有增加产热的功能，肾上腺素直接由(交感神经副交感神经)支配。25.效应细胞毒性T细胞(CTL)在细胞免疫中起着非常重要的作用，可以识别MHC呈递的抗原，并与之结合，使靶细胞裂解。己知T淋巴细胞只能识别自身MHC呈递的抗原，而不能识别其他MHC呈递的抗原，也不对自身MHC发生作用。请设计实验验证该结论，以小鼠为实验材料，完善实验思路。（提示：CTL可以使被感染的细胞全部裂解，导致s1C释放出来，使悬浮液有大量放射性)实验材料：被同位素s1C标记不同遗传背景的两个品系的小鼠甲和乙腹腔中的单核巨噬细胞（作为CTL的靶细胞），LCMV病毒，被sCr标记的LCMV病毒感染的甲、乙品系鼠的单核巨噬细胞（作为CTL的靶细胞），小鼠品系甲、乙，普通细胞培养液，培养皿若干，放射性检测仪等。(1)实验思路：①将LCMV病毒注射到小鼠甲体内，获得发生免疫的老鼠，无菌操作取小鼠的脾脏，并分离出CTL。②取培养皿若干，随机均分3组，加入定量且适量的③实验分组组1：等量的CTL细胞十。组2：等量的CTL细胞十d组3：等量的CTL细胞+适量的同位素1Cr标记甲鼠的单核巨噬细胞。④将3组培养皿放在相同且适宜的环境下培养，一段时间后测悬浮液的放射性。⑤对实验结果进行统计分析。(2)实验结果：以柱形图的形式来表示实验结果（已知组2中悬浮液有少量的放射性）(3)回答下面问题：①组2中悬浮液有少量的放射性的原因是」②免疫应答也叫，LCMV病毒感染小鼠后，能发生的免疫应答类型有。③CTL在生物体内的作用对象是，引起的靶细胞的裂解属于细胞试卷第7页，共7页
