综英5 Unit4 课后练习参考答案

Unit 4 Part I Listening Task Script for the recording: You may recall from Unit One, the author Eudora Welty telling us how she, in her early childhood, developed a love for reading under the influence of her parents. Perhaps you'd like to know what her teachers were like. Well, let's listen to what she has to say about them: Every school week, visiting teachers came on their days for special lessons. On Mondays, the singing teacher blew into the room fresh from the early outdoors, singing in her high soprano "How do you do?" to do-mi-sol-do, and we responded in chorus from our desks, "I'm ve-ry well", to do-sol-mi-do. Miss Johnson taught us rounds —"Row row row your boat gently down the stream", — and "Little Sir Echo," with half the room singing the words and the other half being the echo, a competition. She was from the North, and she was the one who wanted us all to stop the Christmas carols and see snow. The snow falling that morning outside the window was the first most of us had ever seen, and Miss Johnson threw up the window and held out wide her own black Cape and caught flakes on it and ran, as fast as she could go, up and down the ais1es to show us the real thing before it melted. Thursday was Miss Eyrich and Miss Eyrich was Thursday. She came to give us physical training. She wanted no time on nonsense. Without greeting, we were marched straight outside and summarily divided into teams (no choosing sides), put on the mark, and ordered to get set for a relay race. Miss Eyrich cracked out "Go!" Dread rose in my throat. My head swam. Here was my turn, nearly upon me. (Wait, have I been touched —was that slap the touch? Go on! Do I go on without our passing a word? What word? Now am I racing too fast to turn around? Now I'm nearly home, but where is the hand waiting for mine to touch? Am I too late? Have I lost the whole race for our side?) I lost the relay race for our side before I started, through living ahead of myself, dreading to make my start, feeling too late prematurely, and standing transfixed by emergency, trying to think of a password. Thursdays still can make me hear Miss Eyrich's voice. "On your mark —get set — go!" V ery composedly and very slowly, the art teacher, who visited each room on Fridays, paced the aisle and looked down over your shoulder at what you were drawing for her. This was Miss Ascher. Coming from behind you, her deep, resonant voice reached you without being a word at all, but a sort of purr. It was much the sound given out by our family doctor when he read the thermometer and found you were running a slight fever, " Um-hm. Um-hm." Both alike, they let you go right ahead with it. After Listening 1.On Mondays, Miss Johnson, our singing teacher, would blow into the room, singing in her high soprano "How do you do?" to do-mi-sol-do, and we students would respond in chorus from ouir desks, "I'm very well", to do-sol-mi-do. 2.Miss Eyrich gave us physical training on Thursdays. She wanted no time on nonsense. Without greeting, she ordered us to march straight outside and get set for a relay race. 3.In a very composed and slow manner, the art teacher Miss Ascher would pace the aisle and

Unit4 课文翻译及课后练习答案

Unit4 无子女家庭：违背十万年来的繁衍规律 课文翻译： 二十好几的凯茜、韦恩夫妇结婚已有五年之久，没有孩子。上次凯茜娘家有人问：“你们打算什么时候要孩子，组成一个家庭呢?”她答道：“我们已经是个家庭啦!” 凯茜与韦恩属于决定不要孩子的年轻已婚夫妇群体，其人数正在日益增长。最近一项调查显示在过去的五年中，年龄在25至29岁之间妇女不愿生养的百分比几乎翻了一番，在18至24岁的已婚妇女中几乎增至三倍。在这个似乎大胆反抗生物性和社会性的决定后面隐藏着什么原因呢? 或许最能公开坦陈心曲的无子女夫妇是《婴儿陷阱》一书的作者：埃伦，派克，其夫威廉，一位广告总经理兼全国不生养夫妇协会主席。派克夫妇认为他们和协会均无意反对生儿育女，不过是反对不管人们是否愿意和需要孩子就迫使人们传宗接代的社会压力。 “这是一种生活方式的选择，”埃伦说，“我们选择自由和自愿，清净和闲暇。这也是一个朝哪个方向付出努力的问题——在你自己的小家庭之内或在一个大的社团之中。这一代人面临有关地球生命延续的严重问题以及生命质量的问题。我们的孙辈也许将购票去观赏最后一批红杉或排队去获取氧气配给。有人抱怨在回到有五个孩子的家途中被交通堵塞困住好几个小时，但是他们不能将孩子与交通堵塞联系起来。在一个受到人口过剩一系列后果威胁的世界上，我们正在参与一项事业使膝下无子的生活模式为社会所接受并受世人尊重。太多的孩子作为一种文化强制的后果而呱呱坠地，离婚和虐待儿童的相关统计充分揭露了这一结果。” 埃伦的丈夫补充说：“每位朋友、亲戚、同事不停地给你施加压力，劝你要孩子，说什么‘发现你生活中失去的东西’。好多好多人很晚才发现，所谓他们失去的东西其实是他们完全不适合做的事情。” 埃伦还说：“从抱第一个洋娃娃开始，大到欣赏电视肥皂剧，成年后参加鸡尾酒会，无形之中，总有一种压力要你为人父母。但是让我们来看看养育失败的比率吧，或许天下父母应该视为像当医生一样的专门职业。有些人擅长此道，他们应当生养孩子；有些人一窍不通，他们应该认为他们还有其他的选择。” 专业观察家同意这一看法：很多人生养孩子没有正当的理由，有时候则完全没有理由。男人常常稀里糊涂就当上了父亲，根本就没有作出审慎的选择；对许多妇女来说，怀孕能够成为一种方式来逃避不可解决的冲突，譬如，迅速获得名分，或改进自己的不良形象，以及满足童年时代未曾得到的关注和关爱的需要。 我与许多人类行为领域的专家交谈，探讨为什么那么多年轻夫妇决定不要孩子，他们的看法也是众说纷纭。一位家庭治疗专家把不要孩子的决定描写为“对当今世界形势基本的本能反应”，暗示像动物群居本能那样的东西正在起作用，来应对人口过剩、城市拥挤、环境污染与核战争危险。群居本能促使妇女感到繁殖人口有违心愿，并指引她们去寻找在家庭生活之外实现自我价值的新方式。 不止一位精神病医生暗示，凡是不愿生育的人有都自恋癖——觉得自己心甘情愿迫不得已，为照顾别人与受人照顾这个互相对立的内心冲突自圆其说。有位精神病医生说：“这些人不能容忍照顾孩子的想法，他们没有多余的爱分享给孩子，”并补充道，“你们这是对亘古以来人类繁衍生生不息的离经叛道。”他的另一位同事插话说：“情有可原嘛，我们谁不想为我们的欠缺找理由? 且不论他

（新教材）高中生物必修二全册课后“练习与应用+复习与提高” 汇总（附答案） 第1章遗传因子的发现 第1节孟德尔的豌豆杂交实验(一) 【练习与应用】 一、概念检测 1.在孟德尔的一对相对性状的豌豆杂交实验中，B都表现为显性性状，F的自交后代却出现了性状分离。据此判断下列相关表述是否正确。 (1)隐性性状是指生物体不能表现出来的性状。(×) (2)纯合子的自交后代不会发生性状分离，杂合子的自交后代不会出现纯合子。(×) 2.人眼的虹膜有褐色的和蓝色的，褐色是由显性遗传因子控制的，蓝色是由隐性遗传因子控制的。已知一个蓝眼男人与-一个褐眼女人(这个女人的母亲是蓝眼)结婚，这对夫妇生下蓝眼孩子的可能性是(A) A.1/2 B. 1/4 C.1/8 D.1/6 3.观察羊的毛色遗传图解，据图回答问题。 (1)毛色的显性性状是白色，隐性性状是黑色 (2)白毛羊与白毛羊通过有性生殖产生的后代中出现了黑毛羊，这种现象在遗传学上称为性状分离。产生这种现象的原因是白毛羊为杂合子，杂合子自交时会出现性状分离。即雌雄白毛羊均可形成含有控制黑毛的遗传因子的配子，雌雄配子随机结合，会产生黑毛羊。 二、拓展应用 1.水稻的非糯性和糯性是一对相对性状，非糯性花粉中所含的淀粉为直链淀粉，遇碘变蓝黑色，而糯性花粉中所含的是支链淀粉，遇碘变橙红色。现在用纯种的非糯性水稻和纯种的糯性水稻杂交，取F?花粉加碘液染色，在显微镜下观察，半数花粉呈蓝黑色，半数呈橙红色。请回答下列问题。 (1)花粉出现这种比例的原因是什么? F?水稻细胞含有一个控制支链淀粉合成的遗传因子和一个控制直链淀粉合成的遗传因子。在F?形成配子时，两个遗传因子分离，分别进入不同的配子中，含支链淀粉遗传因子的配子合成支链淀粉，遇碘变橙红色;含直链淀粉遗传因子的配子合成直链淀粉，遇碘变蓝黑色，其比例为1:1。 (2)实验结果验证了什么? 分离定律。即在F?形成配子时，成对的遗传因子发生分离，分离后的遗传因子分别进入不同的配子中。 (3)如果让F?自交，F?中花粉有2种类型。 2.某农场养了一群马，马的毛色有栗色和白色两种。已知栗色和白色分别由遗传因子B 和b，控制。育种工作者从中选出一匹健壮的栗色公马，拟设计配种方案鉴定它是纯合子还是杂合子(就毛色而言)。请回答下列问题。 (1)在正常情况下，一匹母马一次只能生一匹小马。为了在个配种季节里完成这项鉴定，应该怎样配种? 将被鉴定的栗色公马与多匹白色母马配种，这样可在一个季节里产生多匹杂交后代。 (2)杂交后代可能出现哪些结果?如何根据结果判断栗色公马是纯合子还是杂合子? 杂交后代可能有两种结果:一是杂交后代全部为栗色马，此结果说明被鉴定的栗色公马很可能是纯合子;二是杂交后代中既有白色马，又有栗色马,此结果说明被鉴定的栗色公马为

高中生物必修二课时训练第一章第二节孟德尔的豌豆杂交实验二

第二节孟德尔的豌豆杂交实验（二） 一、选择题 1．下列有关孟德尔遗传规律的说法错误的是() A．叶绿体基因控制的性状遗传不遵循孟德尔遗传规律 B．受精时，雌雄配子的结合是随机的，这是得出孟德尔遗传规律的条件之一 C．孟德尔发现分离定律与自由组合定律的过程运用了假说—演绎法 D．基因型为AaBb的个体自交，其后代一定有四种表现型和9种基因型 解读：孟德尔遗传规律适用于真核生物有性生殖过程中核基因的遗传；在受精过程中雌雄配子随机结合且机会均等；孟德尔研究分离定律与自由组合定律时用的方法是假说—演绎法；孟德尔用统计学的方法得出了杂交或自交后代出现一定的分离比，这是对多数个体及后代统计的结果，而一个个体自交具有偶然性，很多情况下不表现相应的表现型、基因型及一定的比例，故D项错误。 答案：D 2．四籽野豌豆的染色体数目为2n＝12，现有—个基因型为Mm的野豌豆植株，所结豆荚中有三个饱满豆粒和一个“空瘪粒”。下列有关分析正确的是() A．该豆荚果皮的基因型是Mm的概率为1/2 B．该豆荚中所结三粒种子种皮中的细胞含有18条染色体 C．所结三粒种子的基因型都是Mm的概率为1/8 D．每个花粉中含有2个精子，因此该豆荚至少需要2粒花粉才能得到4粒种子 解读：豆荚的果皮和种皮与母本植株的基因型、染色体数目相同；被子植物进行双受精，因此该豆荚至少需要4粒花粉才能得到4粒种子；豌豆自花传粉，闭花受粉，所结种子的基因型为Mm 的概率为1/2，三粒种子的基因型都是Mm的概率为1/8。 答案：C 3．某育种专家在农田中发现一株大穗不抗病的小麦，自花授粉后获得160粒种子，这些种子发育成的小麦中有30株大穗抗病和若干株小穗抗病，其余的都不抗病。若将这30株大穗抗病的小麦作为亲本自交，在其F中选择大穗抗病的再进行自交，理论上F中能稳定遗21传的大穗抗病 小麦占F中所有大穗抗病小麦的() 2 A．2/10 B．7/10 C．2/9 D．7/9 解读：本题考查基因分离定律的应用。首先由题意确定大穗不抗病是显性性状。所以作1211为亲本的大穗抗病小麦的基因型为AAbb和Aabb，自交后代F中大穗抗病的为AAbb和 13323- 1 - / 8 327AabB。在大穗抗病中，AAbb和Aabb分别占、。再进行自交，F中大穗抗病的为AAbb 255101771和Aabb，理论上F中能稳定遗传的大穗抗病小麦占F中所有大穗抗病小麦的÷(＋)＝225101057。9答案：D 4．已知位于常染色体上的两对独立遗传的基因控制着鸡羽毛色素的产生和沉积。在一个位点上，显性基因可产生色素，隐性基因则不产生色素；在另一位点上，显性基因阻止色素的沉积，隐性基因则可使色素沉积。小鸡羽毛的着色，必须能产生并沉积色素，否则为白色毛。如果表现型为白色的鸡(两位点均为隐性纯合子)和另一种表现型为白色的鸡(两位点均为显性纯合子)进行杂交，
