Lesson Three（2学时）Cellular Reproduction: Mitosis and Meiosis 教学目的：使学生掌握细胞的有丝分裂和无丝分裂的作用机理，有丝分裂和无丝分裂之间的区别和相同点。相关英语词汇以及主要用法。教学重点：有丝分裂和无丝分裂中相关的概念和功能，及相关英语词汇的掌握教学难点：专业英语词汇的记忆讲授方法：以学生翻译为主，老师讲解相关专业知识辅助学生理解授课时间：4月12日教学内容： The Nucleus and ChromosomesThe cell nucleus is the main repository of genetic information. Within the nucleus are the chromosomes tightly coiled strands of DNA and clusters of associated proteins. Long stretches of the continuous DNA molecule wind around these clusters of proteins, or histones, forming beadlike complexes known as nucleosomes. More coiling and supercoiling produces a dense chromosome structure. Each long strand of DNA combines with histones and nonhistone proteins to make up the substance chromatin.细胞核是贮藏遗传信息的主要场所。DNA盘绕成螺旋线以及相关的成簇蛋白质。DNA螺旋线缠绕成簇的组蛋白形成珠链状的核小体。这些螺旋和超螺旋形成致密的染色体组结构。每个长链DNA与组蛋白和非组蛋白一起构成染色质物质。 A pictorial display of an organism's chromosomes in the coiled, condensed state is known as a karyotype. Karyotype reveal that in most cells all but sex chromosomes are present as two copies, referred to as homologous pairs. Non-sex chromosomes are called autosomes. Organisms whose cells contain two sets of parental chromosomes are called diploid; those with cells containing a single set of parental chromosomes are called haploid. 染色体致密的超螺旋状态我们称染色体组。除了性染色体外，大多数细胞的染色体组成对出现，称同源染色体对。非性染色体称常染色体。生物细胞含有两套父母本染色体的称二倍体；含有单套染色体的称单倍体。 The Cell CycleThe cell cycle is a regular sequence in which the cell grows, prepares for division, and divides to form two daughter cells, each of which then repeats the cycle. Such cycling in effect makes single-celled organisms immortal. Many cells in multicellular organisms, including animal muscle and nerve cells, either slow the cycle or break out of it altogether.在细胞生长过程中，细胞循环遵循特定程序，分裂准备，分裂成2个子细胞，子细胞再循环。此循环使得单细胞永生。多细胞生物中的许多细胞，包括动物肌肉和神经细胞，要么降低循环速度，要么同时分裂。 The normal cell cycle consists of four phases. The first three include G1, the period of normal metabolism; S phase, during which normal synthesis of biological molecules continues, DNA is replicated, and histones are synthesized; and G2, a brief period of metabolism and additional growth. Together the G1, S, and G2 phases are called interphase. The fourth phase of the cell cycle is M phase, the period of mitosis, during which the replicated chromosomes condense and move and the cell divides. It is believed that properties of the cell cytoplasm control the cell cycle, along with external stimulators and inhibitors such as chalones. 正常细胞循环由4个时期组成。头三期包括G1,正常新陈代谢；S期,正常新陈代谢同时，DNA 复制，组蛋白合成；G2 期，短期的新陈代谢和少许生长。G1, S, 和G2称分裂间期。最后是M期，有丝分裂期，复制的染色体组浓缩，移动并细胞分裂。据称是染色质控制了细胞循环，伴随外部激活因子和抑制因子如抑素。 Mitosis: Partitioning the Hereditary MaterialBiologists divide the mitotic cycle into four phases. At the beginning of prophase the chromosomes each consist of two highly condensed chromatids attached to each other at a centromere. As prophase ends and metaphase begins, the condensed chromosomes become associated with the spindle. Eventually the chromosomes become
第三课Lesson Three 一、教学内容 1．词汇（略）。 2．句型：1)Pleasedon'tcallmeLily.2)Whohasaruler?3)Youlookthesame. 3．语法：复习现在进行时。 二、教具 录音机、尺子等学习用具（某位同学保管）。 三、课堂教学设计 1．复习值日生报告。 2．教师板书LessonThree及Thethirdlesson,教学生thrid这个词。然后在黑板上划几条线，均故意划斜，擦掉后，问大家：Whohasaruler?让大家猜这句话的意思。启发有尺子的同学与老师产生以下对话: T：Whohasaruler? S1：Ihaveonehere/aruler,Mr×(Ms×). T：MayIborrowit,please? S1：Certainly.Hereyouare. T：Thankyou. S1：You'rewelcome. 尺子肯定不够长度，教师借助手势，又问大家： T：Oh,it'sashortruler.Whohasalongone? S2：（即事先拿着老师尺子的同学）Ihaveone,Mr×(Ms×).Hereyouare.
T：Thankyou,×××（故意将对方名字叫错）。教师启发这位同学用英语说出: S2：Pleasedon'tcallme×××.I'm×××.（手指刚才提到的那位同学）That's×××! T：Sorry. 3．准备放课文第1段录音。板书听前提问(Pre-listeningquestions)：1)Whatwouldtheteacherliketoborrow?2)（用汉语）为什么吴老师把人搞错？ 放录音一至两遍，指导学生回答这两个问题。教师解释Pleasedon'tcallme…和Youlookthesame.这两句（见难点讲解1、2）。再放录音，学生打开书跟读三遍。 4．教师将全班分为三大组，分别扮演课文中Teacher,LiLet和Lucy的角色。教师在前面使用尺子等学习用具，指挥全班模仿课文将对话表演下来。如果困难较大，可再跟读两至三遍课文，并要求学生跟读课文时，尽量不看书。指挥学生表演对话，具体做法参考第二课教学步骤4。如时间允许，可让学生交换角色。 5．教师指导学生就课文第2部分插图提问，并予以正确应答。可先请若干同学进行口头回答，然后要求学生笔答。 6．复习现在进行时的构成及用法。 7．布置作业 1）听录音，朗读课文；2）抄写生词，书面回答课文第2部分的提问；3）完成练习册习题。
