    15.ACD【解析】矿山修复过程中原有的土壤条件基本保留,发生了次生演替,A正确;矿山修复过程中生物组分增多,提高该系统的抵抗力稳定性,B错误;通过人工制造表土、植树种草等措施可加速恢复矿区生态环境,C正确;矿山生态修复考虑生态、经济和社会效益,遵循生态工程的整体原理,D正确。16.AB【解析】对小鼠注射GP3蛋白,小鼠发生体液免疫并产生相应的抗GP3蛋白抗体,A正确;①过程是将细胞甲和S20细胞融合,诱导动物细胞融合的常用方法有PEG融合法、电融合法和灭活病毒诱导法等,B正确;融合后的细胞至少需要经过两次筛选,第二次筛选需进行克隆化培养和抗体检验,C错误;由一个B淋巴细胞增殖形成的细胞群所产生的单一型抗体分子就称为单克隆抗体,D错误。三、非选择题(共60分)17.(除标明外,每空1分,共10分)(1)H2 O NADP(2分)O2(2分)(2)电子在沿类囊体膜传递过程中有逸出(流失或散失)(2分)(3)强实验C组(抑制类囊体蛋白PsbS)与实验B组(抑制叶黄素转化)相比较,C组(抑制类囊体蛋白PsbS)光合作用效率降低更大(2分)【解析】(I)从图中可以看出,光系统Ⅱ可以将水光解产生e、氧气、H+,e经过一系列的传递体形成电子流,接受电子的是NADP+,该物质接受电子和H后,生成了NADPH。在有氧呼吸过程中产生的H和e,与NAD生成NADH,NADH与氧气反应生成水。(2)PSⅡ将e传递给质醌使之还原,PSI从质醌夺取e使之氧化,由于电子在沿类囊体膜传递过程中有逸出,故一般植物的PSⅡ:PSI的比率大约为1.5:1。(3)据图可知,实验C组(抑制类囊体蛋白PsbS)与实验B组(抑制叶黄素转化)相比较,C组(抑制类囊体蛋白PsbS)光合作用效率降低更大,因此在高光照条件下,类囊体蛋白PsS数量变化比叶黄素转化对绿色植物的保护作用强。18.(除标明外,每空2分,共13分)(1)滋养层(1分)(2)染色体结构和数目变异(3)①XB所在的b所在的②bbXsRYX③Ⅱ19.(除标明外,每空1分,共12分)(1)自由扩散分级调节激素起作用后即失活(2)G℃可抑制细胞因子释放,促进淋巴细胞凋亡,降低机体的免疫排斥反应(3)乙酰胆碱和抗原(2分)去甲肾上腺素释放减少,使T细胞释放乙酰胆碱减少,减弱了对B细胞的刺激(2分)(4)①正常造血干细胞并注射适量X抗原②异常造血干细胞并注射等量X抗原③减少实验误差④抗X抗原的抗体产生量【解析】(1)GC是类固醇激素,进入细胞的方式为自由扩散;激素发挥作用后即失活,所以激素需要不断地合成,GC的分泌受到下丘脑一垂体一肾上腺轴的分级调节。(2)由题意可知,GC可抑制细胞因子的释放,降低免疫系统的功能,在器官移植时,可使用适量的GC以降低免疫排斥反应,提高成功率。(3)B细胞可以接受抗原的刺激增殖分化,由图2可知,B细胞还可以接受乙酰胆碱的信号刺激;去除脾神经后,去甲肾上腺素释放减少,使T细胞释放乙酰胆碱减少,减弱了对B细胞的刺激。(4)本实验的目的是证明小鼠B细胞缺少胆碱类受体导致体液免疫能力降低,所以实验的自变量是胆碱类受体是否被破坏,实验设计思路为:取生理状态相同的小鼠若干只,去除小鼠自身造血干细胞,获得不产生B细胞的小鼠,随机均分为两组,将其中一组小鼠移植正常造血千细胞并注射X抗原作为对照组,另一组小鼠移植异常造血千细胞并注射X抗原作为实验组,一段时间后,检测两组小鼠抗X抗体的产生量,为了减少实验误差,要对对照组和实验组均测定多只小鼠。故①为正常造血干细胞并注射适量X抗原;②为异常造血干细胞并注射等量X抗原;③为减少实验误差;④为抗X抗原的抗体产生量。生物学参考答案(附中版)一3

    35.B。推理判断题。根据最后一段伍德曼的话“The work we've donespending years working with a group to learnhow they do what they do and then translating that into something useful for scientists-is critical to movingconservation forward(我们花了多年时间与一个小组合作,了解他们是如何做的,然后将其转化为对科学家有用的东西,这对推动保护工作至关重要)”可知,伍德曼认为他们的工作为鹦鹉保护方面的科学家提供了宝贵的参考,故选B。【语篇导读】这是一篇说明文。文章主要分析了飞机上食物尝起来没有味道的原因。36.E。根据上文“How many times have you complained about airline food being tasteless'?(你有多少次抱怨飞机上的食品无味?)”可知,“我们”时常抱怨飞机上食物寡淡无味。再由“the reason might be a change in our ability toperceive taste(原因可能是我们感知味道的能力发生了变化)”可知,这可能是我们自身的原因,而不是食物的问题。故选E项。37.C。根据上文“The air inside airplane cabins is far more dry than the air we breathe on the ground.(机舱内的空气比我们在地面上呼吸的空气干燥得多。)”可知,机舱内的空气更干燥些,再根据下文“In an environment like this,your powers of taste and smell begin to drift away.(在这样的环境中,你的味觉和嗅觉能力开始衰退。)”可知,味觉和嗅觉的能力都开始衰退,说明干燥的程度很严重,因此,设空处可进一步描述干燥的程度。C项“在某些情况下,它甚至比某些沙漠还要干燥。”进一步补充说明空气的干燥程度,符合语境。故选C项。38.D。根据上文“In the pressurized cabin a passenger's bodily fluids will move upwards and the nasal cavities(鼻腔)swell.The swelling messes with our taste buds,making the food taste unappealing.You might know how dining insuch conditions feel,since we've all fought colds in the past..(在压力舱中,乘客的体液会向上移动,鼻腔会肿胀。肿胀扰乱了我们的味蕾,使食物的味道变得毫无吸引力。你可能知道在这样的条件下吃饭的感觉,因为我们都曾与感冒作过斗争。)”可知,上文部分解释了舱内的压力使得味蕾、鼻腔都发生了变化。这种情况跟“我们”感冒时吃东西总感觉没有味道的情况类似。由此可知,“我们”不能根据自身情况来正确评判食物。故D项“一个病人远不是食品质量的最佳评判者。”符合语境。故选D项。39.A。设空处为小标题,可起到概括总结的作用。根据下文“Bad food can't be blamed merely on the in-cabinconditions too.It's also possible that the food is actually bad.Due to food safety standards,all meals must becooked on the ground and unbreakable.(糟糕的食物也不能仅仅归咎于机舱内的状况。也有可能食物实际上是坏的。根据食品安全标准,所有的饭菜都必须在地面上烹调,而且不易碎。)”可知,舱内生产食物的方式跟一般情况是有所不同的。故选A项。4o.G。根据下文“Apparently,chefs have been trying to adapt recipes in how food tastes at high altitudes.Everyoneneeds to be patient until better solutions for mass food production are found.(显然,厨师们一直在努力调整食谱,以适应高海拔地区食物的口味。在找到更好的大规模食品生产解决方案之前,每个人都需要耐心。)”可知,在飞机上不能使用与地面上相同的食谱,所以厨师着手改进配方。G项“基本上,我们不能使用与地面上相同的食谱来做航空餐。”符合语境。故选G项。【语篇导读】这是一篇以怀念母亲,传承母爱的记叙文。41.B。“take her last breath”表示“在她弥留之际”。42.B。“a river that ran through my parents'backyard”表示“一条流经我父母后院的小河”。43.C。“boundless energy and charm she'dhad”表示“她所拥有的无限的精力和魅力”。44.D。“being restricted to her bed”表示“被限制在病床上,缠绵病榻”。45.A。似乎她健康时所拥有的无限的精力和魅力在她困于病榻几个月后,终于附着在这只活泼的小鸟身上,回来了。46.C。“wore a funny hat'”表示“戴一顶滑稽可笑的帽子”,与前一句的“My mom was the sort of person who wantedeveryone to have a great time.”相呼应。47.D。“never took herself so seriously”表示妈妈“从来不会太把自己当▣事”。48.B。即便在毕业舞会的夜晚她不让我和朋友一起去酒店住,我因此生她气的时候。49.C。或当我不能把分数提高的时候,她对我表示失望的时候,我依然那么爱她。50.A。“bring up my grades'”表示“提高我的成绩”。51.D。她尊重我的隐私。52.A。看到我的优点,她会鼓励;对于我的缺点,她会用幽默的方式一带而过。英语试题参考答案(长郡版)第3页
