单元检测卷07 变异与进化(解析版)
第七单元变异与进化单元练（时间：75分钟，满分：100分）一、选择题（本题共15小题，每小题3分，共45分。
）1．下表是2005-2008年碳青霉烯类抗生素在某医院住院患者中的使用情况统计。
下列叙述错误的是（）A．该细菌的耐药性不断增强体现了生物的适应性B．抗生素直接对细菌的耐药性基因进行选择使耐药基因频率增大C．滥用抗生素是细菌耐药性增强的重要原因D．开发新的抗生素有助于解决细菌耐药性增强的问题【答案】B【分析】基因突变具有普遍性，基因突变为生物进化提供了原材料，自然选择决定进化的方向，题中使用抗生素，就是对细菌的一种选择，使具有抗药基因的细菌保留下来。
【详解】A、随着抗生素的使用，细菌的耐药性增强，体现了细菌对环境改变的适应，A正确；B、抗生素的直接选择对象是抗药性状，而非基因，B错误；C、滥用抗生素使细菌耐药性基因频率增大，导致耐药性增强，C正确；D、开发新的抗生素有助于解决细菌对现有抗生素产生耐药性的问题，毕竟耐药性增强需要一个过程，D正确。
故选B。
2．某昆虫种群由于外界因素的改变，被分割成甲、乙两个种群。
分割后的两个种群中A基因的基因频率变化情况如图所示。
下列叙述不正确的是（）A．原种群个体的基因型可能不只一种B．甲种群中的显性性状个体更适应所处的环境C．0~T过程中，甲、乙种群均发生了进化D．T时刻将甲、乙种群混合，A基因的基因频率恢复到0.5【答案】D【分析】由图可知，甲、乙两个种群A基因频率往不同的方向改变，表明两者所在环境有所区别，对于A基因的选择作用不一样，在T时刻后两个种群的A基因频率趋于稳定。
【详解】A、由于基因频率为0.5，则可能在环境改变前，该种群只有杂合子，也可能AA∶Aa∶aa=1∶2∶1，A 正确；B、甲种群中A 基因的频率定向增大，说明显性性状是有利变异，更加适应环境，B正确；C、甲种群和乙种群在0~T的过程中，基因频率均发生了定向的改变，说明两个种群发生了进化，C正确；D、由于甲种群和乙种群的种群数量不一定在T时刻相同，混合后A的基因频率不一定能恢复到0.5，D错误。

单词是基础，三会四会的单词一定要掌握。
(二)过不好词组第一关。
我们紧紧围绕课后单词，撰写词组，既使学生稳固单词，又稳固了词组。
(三)过好句子关。
句子就是自学英语的重点。
我们准备工作从以下几方面去协助学生剖析所学过的句子。
1、指导学生在语境中复习句子，让学生分清日常交际用语的运用场合。
2、根据句子类型指导学生在比较中备考句子。
3、掌握grammarfocus里的所有句子。
(四)过不好写作第一关。
阅读短文能让学生全面运用所学知识，因此指导学生认真阅读也是英语复习的重要环节，总而言之，要把单词、词组、句子和短文作为一个有机整体，在复习过程中将它们紧密结合出来，合理安排教学内容，提升学生整体运用科学知识的能力。
(五)过好检测关。
当老师把科学知识展开直观的剖析---串联---概括----总结后，存有必要对学生展开必要的检测。
一方面就是对学生存有更好地介绍，另一方面能够展开补漏伯粉。
四.以听说读写为主要途径，指导学生在备考的过程中赢得综合能力的提升。
必须使学生多念，在紧绷的备考阶段同样不忘培育学生朗诵英语的习惯，所有单词、词组、句子等都就是写作材料，都必须指导学生朗诵，必须使学生在多念多说道的基础上不断提升学生听到和写下的能力。
五.注意复习过程中的趣味性，充分调动学生的学习积极性。
我们存有一部分学生对英语自学缺少兴趣，在备考时必须挑选最合适的内容，把内容和形式有机融合，特别注意掌控不好科学知识的难度，必须使学生存有获得成功的机会和体会，尽量提升他们的兴趣，并使他们也能够资金投入到较紧绷的备考中，时能在备考中获得进步。
六.注意做好学生的心理调试工作，对于自感压力太大的同学要耐心地疏导，从思想上为他“减负”，使其能在平静宽松的氛围中进行有序的复习，较好地完成学习任务;对于没有任何心理压力，还没进入复习状态的同学要给予一定的压力，使其在压力之下也能较好地投入到紧张的复习中来;而对于学习困难且心理焦虑烦躁的同学更要给予特别的关爱，一方面要想方设法抽时间为其开小灶，一方面还要不断地鼓励赏识他们，同时要给他们适当地减压，使他们也能保持较好的情绪投入到紧张的复习中，并能尽最大努力取得最好效果。

单元07 化学能与热能-【真题模拟练】(解析版)
单元07 化学能与热能真题模拟练1．（2021·山东）18O标记的乙酸甲酯在足量NaOH溶液中发生水解，部分反应历程可表示为：+OH-ⅠⅡⅢⅣ+CH3O-能量变化如图所示。
已知为快速平衡，下列说法正确的是A．反应Ⅱ、Ⅲ为决速步B．反应结束后，溶液中存在18OH-C．反应结束后，溶液中存在CH318OHD．反应Ⅰ与反应Ⅳ活化能的差值等于图示总反应的焓变【答案】B【详解】A．一般来说，反应的活化能越高，反应速率越慢，由图可知，反应I和反应IV的活化能较高，因此反应的决速步为反应I、IV，故A错误；B ．反应I 为加成反应，而与为快速平衡，反应II 的成键和断键方式为或，后者能生成18OH -，因此反应结束后，溶液中存在18OH -，故B 正确；C ．反应III 的成键和断键方式为或，因此反应结束后溶液中不会存在CH 318H ，故C 错误；D ．该总反应对应反应物的总能量高于生成物总能量，总反应为放热反应，因此和CH 3O -的总能量与和OH -的总能量之差等于图示总反应的焓变，故D 错误；综上所述，正确的是B 项，故答案为B 。
2．（2021·浙江）相同温度和压强下，关于反应的ΔH ，下列判断正确的是A ．12ΔH >0,ΔH >0B ．312ΔH =ΔH +ΔHC ．3212>ΔH ,ΔH ΔH >ΔHD ．423=ΔH H +ΔΔH【答案】C 【分析】一般的烯烃与氢气发生的加成反应为放热反应，但是，由于苯环结构的特殊性决定了苯环结构的稳定性，苯与氢气发生加成反应生成1，3-环己二烯时，破坏了苯环结构的稳定性，因此该反应为吸热反应。
【详解】A ．环己烯、1，3-环己二烯分别与氢气发生的加成反应均为放热反应，因此，21H 0,H 0∆∆＜＜ ，A 不正确；B ．苯分子中没有碳碳双键，其中的碳碳键是介于单键和双键之间的特殊的共价键，因此，其与氢气完全加成的反应热不等于环己烯、1，3-环己二烯分别与氢气发生的加成反应的反应热之和，即312H H H ∆≠∆+∆，B 不正确；C ．环己烯、1，3-环己二烯分别与氢气发生的加成反应均为放反应，21H 0,H 0∆∆＜＜，由于1mol 1，3-环己二烯与氢气完全加成后消耗的氢气是等量环己烯的2倍，故其放出的热量更多，其12H H ∆>∆；苯与氢气发生加成反应生成1，3-环己二烯的反应为吸热反应（4ΔH >0），根据盖斯定律可知，苯与氢气完全加成的反应热342H =H +H ∆∆∆，因此32H H ∆>∆，C 正确；D ．根据盖斯定律可知，苯与氢气完全加成的反应热342H =H +H ∆∆∆，因此342H -H H ∆∆=∆，D 不正确。
