    口■■■口口口11.A组、B组培养液中葡萄糖质量分数较高,对应培养液中的细胞密度较高,培养瓶内的培养液体积会影响供氧情况,进而影响酵母菌的增殖,B组培养瓶内培养液多、供氧较少,其中酵母菌增殖慢、细胞密度后达到最大值对应曲线①,A组对应曲线②,A错误。C组、D组培养液中葡萄糖质量分数较低,对应培养液中的细胞密度较低,而C组培养瓶内培养液少、供氧较多,酵母菌增殖快、细胞密度先达到最大值对应曲线④,D组对应曲线③:D组培养瓶内的葡萄糖总量更多,K值更高,B正确。D组和B组的葡萄糖质量分数不同,营养物质的供应情况不同,导致其实验结果不同,C正确。适当增加接种量,不会改变培养液中营养物质的含量,不影响种群的K值大小,但到达K值的时间会提前,D正确。12.物种数相同的情况下,迁入率由大小关系为近大岛>近小岛>远大岛>远小岛,A正确。物种数相同的情况下,物种灭亡率的大小关系为小岛>大岛,B正确。面积相同时距离大陆越近的岛上,迁入率和灭亡率曲线的交叉点对应的数值越大,预测岛上的物种数越多,C错误。距离大陆相同的岛屿面积越小,迁入率和灭亡率曲线的交叉点对应的数值越小,预测岛上的物种数越少,D正确。I3.tRNA和RNA不会翻译为蛋白质,A错误。甲硫氨酸处于图中①的位置,B错误。tRNA分子是单链,C错误。核糖体沿着mRNA移动以便合成肽链,移动的方向是从左到右,D正确。14.该细胞可能是雌性动物细胞,也可能是处于减数第二次分裂过程中的雄性动物细胞,A错误。该细胞可能处于有丝分裂也可能处于减数分裂过程中,若是在减数第二次分裂过程中,该细胞的染色体只有2个红色荧光或2个绿色荧光,B错误。若该细胞的细胞膜开始向内凹陷,则处于分裂后期,若是减数第一次分裂则细胞两极荧光点的颜色不同,若是减数第二次分裂则细胞两极荧光点的颜色相同,C错误。该细胞可能处于有丝分裂前期,此时细胞中染色体可能散乱分布,细胞中存在2个染色体组,D正确。15.秋季叶片变黄,h(1-2),A错误。春季b基因频率为n,故B为1-n,BB+Bb为m1,故bb为1-m,所以1/2×(Bb基因频率)+1-m=n,算出Bb的基因频率为2m+2n-2,B错误。同理,秋季Bb的基因频率为2m2+2n2-2,m2-(2m,+2n2-2)即为BB的频率,为2-m2-2n2,C正确。春季绿翅表型频率m,>m2,D错误。二、非选择题:本题共5小题,共55分。16.(除特殊标注外,每空1分,共11分)(1)原核细胞毒性T(2分)(2)ABC(2分)生物参考答案·第2页(共4页)

    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

    26.B。理解观点、态度。根据倒数第二段中的Cuautle believes that contemporary standardChinese bears a strong phonetic likeness to the language families found in Mesoamerica If youspeak neither standard Chinese nor Purepecha,...you'll likely think they're the same,Cuautle认为Purepecha和汉语普通话在发音上很相似。27.C。理解主旨要义。总览全文可知,作者主要向我们介绍了墨西哥诗人Manuel Cuautle对中国文化的酷爱以及他对中国文化的不断探索,故c项内容为正确答案。注:wordsmith意为“词语大师、作家”。C篇主题语境:人与社会一一科学与技术本文是说明文。现有的全球定位系统不太适用于海洋生物,所以科学家们正在研发适合海洋生物的全球定位系统。28.C。理解具体信息。根据第二段中的Data collected and stored in a tag can be sent to asatellite in bursts if the species in question is one that comes to the surface from time to time知,GPS追踪器适用于那些间或浮出水面的海洋生物。29.D。理解具体信息。根据倒数第二段中的They called them“sound fixing and ranging”(sofar)channels.Sound sent out in one of these channels echoes between the layers above andbelow,thus staying in the channel Thus constrained,a sound wave can travel hundreds ofkilometres before it becomes too weak to detect可知,声音能够在此停留一段时间且保持一定的强度。30.A。理解具体信息。根据最后一段中的Pongs are so called because they are similar to sonar“pings”,but of lower frequency可知,pings频率较高。31.B。理解主旨要义。本文由常规的GPS系统说起,引出了适用于海洋的GPS系统,并对这一系统的未来进行了展望,所以B项作为文章标题最贴切。D篇主题语境:人与社会一一体育本文是说明文。文章主要就印度尼西亚如何获得“羽毛球王国”这一美誉进行了解读。32.D。理解具体信息。根据第一段中的On August2 nd when Indonesia got its only gold medalat the Tokyo Olympics,the winning team of Greysia Polii and Apriyani Rahayu collapsed onto thefloor and cried with relief可知,8月2日,当印尼夺得东京奥运会上唯一一枚金牌时,获胜的Poli和Rahayu躺在了地上,流下了激动的泪水。33.B。理解词汇。根据转折连词But和该词后的It has won more titles at the Thomas Cup,themost distinguished tournament,than any other country可知,尽管近几十年中国已发展成为一个羽毛球强国,但印尼才是这项运动的霸主。在最负盛名的汤姆斯杯羽毛球团体赛中,印尼赢得的冠军比其他任何国家都要多。34.C。理解具体信息。根据第三段中的Indonesia is the“home of badminton”和Whereverone travels in Indonesia,says Raja Oktohari,president of the Indonesian Olympic Committee,“within a second you can find people playing badminton.”可知,羽毛球这项运动在印尼广受欢迎。35.A。理解目的。总览全文可知,作者先从两名印尼运动员在东京奥运会上获得金牌这一事件说起,然后讲述了印尼在各类羽毛球大赛中取得的辉煌成就,接着分析了产生这一现象的原因:广泛的群众基础、政府的支持、丰厚的报酬等。由此可见,本文旨在解读一种体育现象。【知识链接】
