【Background information】
Human Cloning—Will it ever happen?
Roslin’s scientists have announced that the nuclear transfer technique (细胞核移植技术)they have applied to produce Dolly could be in theory applied to humans. Whether anyone would try and whether it would work is another matter. But the “what if ” question must now be asked with much more seriousness than before.
Two aspects of the Roslin’s discovery have set the world of biotechnology alight(轰动生物界). One is the fact that a somatic tissue (体组织)from an adult has been used to produce a live animal. This has rewritten one of the laws of biology.
The second is that you can clone a large mammal from the cells of an adult of the species. It is this second aspect that has caught the public imagination.
Scientifically it would still be a big leap to go from cloning a sheep to cloning humans, and it is premature (为时尚早)to discuss this as if it were inevitably (不可避免地)going to happen. But this discovery means that we have at least got to ask the question “what if ?”.
Cloning Humans is Ethically(伦理上地) unacceptable. Dr.Wilmut, the scientist involved, and his colleagues at Roslin have made it quite clear that they think that to clone humans would be unethical. (非伦理的)

人教版高中物理选修3-1 全册知识点总结大全 第一章 静电场 第1课时 库仑定律、电场力的性质 考点1.电荷、电荷守恒定律 自然界中存在两种电荷：正电荷和负电荷。例如：用毛皮摩擦过的橡胶棒带负电，用丝绸摩擦过的玻璃棒带正电。同种电荷互相排斥，异种电荷相互吸引；电荷的基本性质：能吸引轻小物体 1. 元电荷：电荷量c e 191060.1-?=的电荷，叫元电荷。说明：任意带电体的电荷量都是 元电荷电荷量的整数倍。 2.使物体带电也叫起电。使物体带电的方法有三种：①摩擦起电 ②接触带电 ③感应起电。 3电荷守恒定律：电荷既不能被创造，又不能被消灭，它只能从一个物体转移到另一个物体，或者从物体的一部分转移到另一部分，电荷的总量保持不变。 考点2.库仑定律 1. 内容：在真空中静止的两个点电荷之间的作用力跟它们的电荷量的乘积成正比，跟它们之间的距离的平方成反比，作用力的方向在他们的连线上。 2. 公式：叫静电力常量）式中,/100.9(2 292 21C m N k r Q Q k F ??== 3. 适用条件：真空、点电荷。 4. 点电荷：如果带电体间的距离比它们的大小大得多，以致带电体的形状体积对相互作用力的影响可忽略不计，这样的带电体可以看成点电荷。 考点3.电场强度 1.电场 ⑴ 定义：存在电荷周围能传递电荷间相互作用的一种特殊物质。 ⑵ 基本性质：对放入其中的电荷有力的作用。 ⑶ 静电场：静止的电荷产生的电场 2.电场强度 ⑴ 定义：放入电场中的电荷受到的电场力F 与它的电荷量q 的比值，叫做该点的电场强度。
⑵ 定义式： q F E = E 与 F 、q 无关，只由电场本身决定。 ⑶ 单位：N/C 或V/m 。 ⑷ 电场强度的三种表达方式的比较 定义式 决定式 关系式 表达式 q F E /= 2/r kQ E = d U E /= 适用 范围 任何电场 真空中的点电荷 匀强电场 说明 E 的大小和方向与检验电荷 的电荷量以及电性以及存在与否无关 Q ：场源电荷的电荷量 r:研究点到场源电荷的距离 U:电场中两点的电势差 d ：两点沿电场线方向的距离 （5）矢量性：规定正电荷在电场中受到的电场力的方向为该点电场强度的方向，或与负电荷在电场中受到的电场力的方向相反。 （6）叠加性：多个电荷在电场中某点的电场强度为各个电荷单独在该点产生的电场强度的矢量和，这种关系叫做电场强度的矢量叠加，电场强度的叠加遵从平行四边形定则。 考点4.电场线、匀强电场 1. 电场线：为了形象直观描述电场的强弱和方向，在电场中画出一系列的曲线，曲线上的各点的切线方向代表该点的电场强度的方向，曲线的疏密程度表示场强的大小。 2. 电场线的特点 ⑴ 电场线是为了直观形象的描述电场而假想的、实际是不存在的理想化模型。 ⑵ 始于正电荷或无穷远，终于无穷远或负电荷，电场线是不闭合曲线。 ⑶ 任意两条电场线不相交。 ⑷ 电场线的疏密表示电场的强弱，某点的切线方向表示该点的场强方向，它不表示电荷在电场中的运动轨迹。 ⑸ 沿着电场线的方向电势降低；电场线从高等势面（线）垂直指向低等势面（线）。 3. 匀强电场 ⑴定义：场强方向处处相同，场强大小处处相等的区域称之为匀强电场。 ⑵特点：匀强电场中的电场线是等距的平行线。平行正对的两金属板带等量异种电荷后，在

选修六Unit 2 A FEW SIMPLE FORMS OF ENGLISH POEMS 简体英文诗 There are various reasons why people write poetry. 人们写诗有着各种各样的理由。Some poems tell a story or describe something in a way that will give the reader a strong impression. 有些诗是为了叙事，或者说是描述某件事并给读者以强烈的印象。Others try to convey certain emotions. 而有些诗则是为了传达某种感情。Poets use many different forms of poetry to express themselves. 诗人用许多不同风格的诗来表达自己的情感。In this text, however, we will look at a few of the simpler forms. 本文只谈了几种格式比较简单的诗。 Some of the first poetry a young child learns in English is nursery rhymes. 孩子们最早学习的英文诗是童谣。These rhymes like the one on the right (A) are still a common type of children's poetry. 像右边的这首童谣（A）至今仍然是常见的。The language is concrete but imaginative, and they delight small children because they rhyme, have strong rhythm and a lot of repetition. 童谣的语言具体但富有想象力，这使得小孩子们快乐，因为它们押韵，节奏感强，并较多重复。The poems may not make sense and even seem contradictory, but they are easy to learn and recite. 童谣不一定有什么意义，甚至有的看来自相矛盾，但是它们容易学，也容易背诵。By playing with the words in nursery rhymes, children learn about language. 通过童谣中的文字游戏，孩子们学习了语言。 （A） Hush, little baby, don't say a word,小宝宝，别说话， Papa's going to buy you a mockingbird.爸爸给你买个小嘲鸟。 If that mockingbird won't sing,小嘲鸟，不会唱， Papa's going to buy you a diamond ring.爸爸给你买个钻石戒。 If that diamond ring turns to brass,钻石戒，变成铜， Papa's going to buy you a looking-glass.爸爸给你买个小镜子。 If that looking-glass gets broke,小镜子，打破了， Papa's going to buy you a billy-goat.爸爸给你买个小山羊。 If that billy-goat runs away,小山羊，跑掉了。 Papa's going to buy you another today.爸爸今天再去给你买一只。 One of the simplest kinds of poems are those like B and C that list things.像（B）和（C）这样的列举事物的清单诗是诗歌中最简单的一种。List poems have a flexible line length and repeated phrases which give both a pattern and a rhythm to the poem.清单诗可长可短，可以重复一些短语，较为灵活。形成固定句型和诗的节奏。Some rhyme (like B) while others do not (like C).有些清单诗有韵脚（如B）,但有一些没有（如C）。 （B） I saw a fish- pond all on fire我看到鱼塘在燃烧 I saw a fish-pond all on fire,我看到鱼塘在燃烧， I saw a house bow to a squire,我看到房子向地主哈腰， I saw a person twelve-feet high,我看到人高一丈八， I saw a cottage in the sky,我看到茅屋在天郊。 I saw a balloon made of lead,我看到气球用铅做， I saw a coffin drop down dead,我看到棺材把死人抛。 I saw two sparrows run a race,我看到两只麻雀在赛跑， I saw two horses making lace,我看到两匹马儿绣花包。 I saw a girl just like a cat,我看到姑娘像只猫，

高二物理选修3-4教案 11、1简谐运动 一、三维目标 知识与技能 1、了解什么就是机械振动、简谐运动 2、正确理解简谐运动图象得物理含义,知道简谐运动得图象就是一条正弦或余弦曲线过程与方法 通过观察演示实验,概括出机械振动得特征,培养学生得观察、概括能力 情感态度与价值观 让学生体验科学得神奇,实验得乐趣 二、教学重点 使学生掌握简谐运动得回复力特征及相关物理量得变化规律 三、教学难点 偏离平衡位置得位移与位移得概念容易混淆;在一次全振动中速度得变化 四、教学过程 引入:我们学习机械运动得规律,就是从简单到复杂:匀速运动、匀变速直线运动、平抛运动、匀速圆周运动,今天学习一种更复杂得运动——简谐运动 1、机械振动 振动就是自然界中普遍存在得一种运动形式,请举例说明什么样得运动就就是振动？ 微风中树枝得颤动、心脏得跳动、钟摆得摆动、声带得振动……这些物体得运动都就是振动。请同学们观察几个振动得实验,注意边瞧边想:物体振动时有什么特征？ [演示实验] (1)一端固定得钢板尺[见图1(a)] (2)单摆[见图1(b)] (3)弹簧振子[见图1(c)(d)] (4)穿在橡皮绳上得塑料球[见图1(e)] 提问:这些物体得运动各不相同:运动轨迹就是直线得、曲线得;运动方向水平得、竖直得;物体
各部分运动情况相同得、不同得……它们得运动有什么共同特征？ 归纳:物体振动时有一中心位置,物体(或物体得一部分)在中心位置两侧做往复运动,振动就是机械振动得简称。 2、简谐运动 简谐运动就是一种最简单、最基本得振动,我们以弹簧振子为例学习简谐运动 (1)弹簧振子 演示实验:气垫弹簧振子得振动 讨论:a.滑块得运动就是平动,可以瞧作质点 b.弹簧得质量远远小于滑动得质量,可以忽略不计,一个轻质弹簧联接一个质点,弹簧得另一端固定,就构成了一个弹簧振子 c.没有气垫时,阻力太大,振子不振动;有了气垫时,阻力很小,振子振动。我们研究在没有阻力得理想条件下弹簧振子得运动。 (2)弹簧振子为什么会振动？ 物体做机械振动时,一定受到指向中心位置得力,这个力得作用总能使物体回到中心位置,这个力叫回复力,回复力就是根据力得效果命名得,对于弹簧振子,它就是弹力。 回复力可以就是弹力,或其它得力,或几个力得合力,或某个力得分力,在O点,回复力就是零,叫振动得平衡位置。 (3)简谐运动得特征 弹簧振子在振动过程中,回复力得大小与方向与振子偏离平衡位置得位移有直接关系。在研究机械振动时,我们把偏离平衡位置得位移简称为位移。 3、简谐运动得位移图象——振动图象 简谐运动得振动图象就是一条什么形状得图线呢？简谐运动得位移指得就是什么位移？(相对平衡位置得位移) 演示:当弹簧振子振动时,沿垂置于振动方向匀速拉动纸带,毛笔P就在纸带上画出一条振动曲线 说明:匀速拉动纸带时,纸带移动得距离与时间成正比,纸带拉动 一定得距离对应振子振动一定得时间,因此纸带得运动方向可以代

Unit 2 Cloning 阅读理解组块专练——练速度 (限时：30分钟) Ⅰ.阅读理解 A At your next meeting, wait for a pause in conversation and try to measure how long it lasts. Among English speakers, chances are that it will be a second or two at most. But while this pattern may be universal, our awareness of silence differs dramatically across cultures. What one culture considers a confusing or awkward pause may be seen by others as a valuable moment of reflection and a sign of respect for what the last speaker has said. Research in Dutch (荷兰语) and also in English found that when a silence in conversation stretches to four seconds, people start to feel uneasy. In contrast, a separate study of business meetings found that Japanese people are happy with silences of 8.2 seconds — nearly twice as long as in Americans' meetings. In Japan, it is recognised that the best communication is when you don't speak at all. It's already a failure to understand each other by speaking because you're repairing that failure by using words. In the US, it may originate from the history of colonial (殖民地的) America as a crossroads of many different races. When you have a complex of difference, it's hard to establish common understanding unless you talk and there's understandably a kind of anxiety unless people are verbally engaged to establish a common life. This applies also to some extent to London. In contrast, when there's more homogeneity,_perhaps it's easier for some kinds of silence to appear. For example, among your closest friends and family it's easier to sit in silence than with people you're less well acquainted with. A．The Dutch. B．Americans. C．The English. D．The Japanese. 解析：选D 细节理解题。根据第二、三段内容可知，日本人在谈话中沉默时间最长。
