本单元包括以下部分：
Section 1: Background information on culture relics
I. What is a culture relic? 何谓“文化遗产”?
Cultural relics are physical reminders of what different peoples valued in the past and continue to value now. Without these relics, we could not cherish cultural traditions as much or appreciate the lives of the people who practiced those traditions. Although we may not often consider it, cultural relics are not only the possession of one culture. In a larger sense, it can be said that they belong to all peoples. For these reasons, this unit describes cultural relics not from China but other places. Looking at it from another angle, it can also be said that cultural relics preserves some aspect of cultural heritage and each relic, regardless of whether the same hands created many examples of it, is still a unique cultural expression and contribution.
II. The cultural relics of China in the world heritage site list《世界文化遗产名录》中的30处中国文遗产
本单元的主题是“文化遗产”，学生很可能已经亲身接触过当地的文化遗产，或是能过电视、报纸等媒体对此有了一定的了解，因此，在课前教师可让学生列举国内外著名的文化遗产，然后对“文化遗产”给出定义、分类或划分标准。到2004年底，我国已有30处文物古迹和自然景观被联合国科教文组织世界遗产委员会列入《世界遗产名录》，以下是这些文化遗产的名称、性质和列人《世界遗产名录》的年份：

重点句子
1．Frederick William I, the king of Prussia, could never have imagined that his greatest gift to the Prussian people would have such an amazing history.
这是一个含有宾语从句的主从复合句，主语是Frederick William I，其后的the king of Prussia, 是主语的同位语，could never have imagined 是主句的谓语。to the Prussian people是介词短语做定语，修饰that引导的宾语从句的主语gift
could never have imagined 表示对过去情况的推测。Could 也可以用can,但can主要用于否定和疑问句中，could 可用于各种时态，并且比can更委婉。
2. The design of the room was in the fancy style popular in those days.
句中in the fancy style popular in those days.做表语，popular in those days.做
the fancy style的定语。
句中的design是名词，意为设计，图案，构思
Design还可以做及物动词意为设计，计划。常用于被动结构中，be designed to do sth 企图，打算做某事。
3. However, the next king of Prussian, Frederick William I, to whom the amber room belonged, decided not to keep it .
本句是主从复合句the next king of Prussian, decided not to keep it .是主句，其中decided是谓语动词。to whom the amber room belonged, 是由whom引导的非限制性定语从句，修饰先行词Frederick William I,且介词to 提前
Belong 是不及物动词，意思是“属于”，如果接宾语，通常与to连用，不用于被动语态和进行时态。
4. sadly，although the amber room was consider one of the wonder of the world, it is now missing. 这是一个主从复合句，it is now missing.是主句，although引导的让步状语从句修饰主句，句
首的sadly也做状语，修饰主句。
Although是连词，意为尽管，虽然，引导让步状语从句。Although 引导让步状语从句时，主句不能用but。但可以用yet和still。
5. After that, what happened to the amber room remains a mystery.
Remain 在这里做系动词，表示继续保持，后接形容词，分词，名词，介词短语等。Remain做不及物动词，意为留下，剩下
Eg.He will remain to accompany you.
Section4 Grammar
定语从句—限定性定语从句与非限定性定语从句
1. 形式不同
限定性定语从句不用逗号，而非限定性定语从句用逗号将其与主句分开。例如：
All the magazines here which have beautiful pictures in them were written by him.
这儿里面有漂亮图画的那些杂志都是他写的。
All the magazines here，which have beautiful pictures in them ，were written by him.
2. 意义不同
限制性定语从句对先行词起限制，确定作用，是先行词不可缺少的定语，如果省去，主句的意思就不完整，不明确或不合逻辑。而非限制性定语和先行词关系松散，只是对先行词做附加说明，如果省去，主句意思仍然完整或清楚。例如：
This is the place where I lived ten years ago.
这是我十年前住过的地方。
She is going to spend the winter holiday in Macao,which returned to china in 1999.她将去澳门度寒假，澳门于1999年回归中国。
3. 关系词
限制性定语从句关系词做宾语时可省略，而非限制性定语从句关系词不可省略。引导非限制性定语从句的关系代词不可用that，指人时用who（主语），whom（宾语），指物时必需用which。例如：
Tom sold his house,which was in downtown.
汤姆卖掉了处在闹市的那套房子。
She had eight children;three of whom lived to grown up.
她生了八个孩子，其中三个都已经长大成人了。
4翻译的语序不同
翻译限定性定语从句，一般先译从句，在译先行词，翻译为“.....的”；翻译非限定性定语从句，一般先译先行词，在译从句，形成两个分句。例如：
I have a sister who works in a hospital.
我有一个在医院工作的姐姐。
I have a sister,who works in a hospital.
我有一个姐姐，她在医院工作。

1.1 孟德尔的豌豆杂交实验（一）（第一课时） 【教学目标】1、阐明孟德尔的一对相对性状的杂交实验。 2、体验孟德尔遗传实验的科学方法和创新思维。 【知识梳理】 一、为什么选用豌豆作为实验材料容易成功？（观察图1-1，1-2，1-3，总结选用豌豆的优点） 1. 豌豆传粉（且闭花受粉），结果是：自花传粉（自交），产生； 自交：两性花的花粉落到同一朵花的雌蕊柱头上的过程叫自花传粉,也叫自交。 杂交：基因型不同的个体之间的交配。 豌豆花大，易于进行人工杂交，即去雄—套袋（防止其它花粉的干扰）—授粉（采集另一种豌豆的花粉，授到去掉雄蕊的花的柱头上），获得真正的杂种； 父本：供应花粉的植株叫父本（♂） 母本：接受花粉的植株叫母本（♀） 正交、反交：若甲作父本、乙做母本为正交，反之为。 2. 具有稳定遗传、的性状，如豌豆茎的高度有悬殊的差异，通过观察很容易区分，进行统计。 性状：是指生物体的形态特征和生理特征的总称。如：豌豆茎的高矮。 相对性状是指一种_____ _的____ __性状的____ _表现类型。如：_____________ 。 设问：豌豆有多对相对性状，孟德尔做杂交实验时是同时观察的吗？他先观察一对相对性状的遗传，并对此进行分析。 二、一对相对性状的遗传实验（观察图1-4） P 纯种的高茎豌豆×纯种的矮茎豌豆 ♀（♂）↓♂（♀） F1高茎豌豆 ↓自交 F2 高茎豌豆矮茎豌豆 3 ：1 思考： F1为什么表现出高茎，没有表现出矮茎的性状？ F2为什么又出现了矮茎？且统计是3：1的数量比？这比值是偶然的吗？ 具有相对性状的两个亲本杂交所产生的F1中__________ _的性状叫显性性状。而 _______________ 的性状叫隐性性状。 性状分离指在______ _后代中，同时显现出________ _和_________ _的现象。 三、对分离现象的解释 1、孟德尔在观察和统计分析的基础上，果断地摒弃了前人融合遗传的观点，通过严谨的推理和大胆的想象，提出了如下假说： （1）性状是由_________ 决定的。遗传因子不融合、不消失。 显性性状：由显性遗传因子控制（用大写D表示） 隐性性状：由隐性遗传因子控制（用小写d表示） （2）体细胞中遗传因子是___________存在。 纯合子是指_________________的个体。如：纯种高茎豌豆：DD；纯种矮茎豌豆：dd 纯合子表现出来的性状能稳定遗传，自交不发生性状分离。 杂合子指_________________的个体，如：F1高茎豌豆：Dd 杂合体表现出来的性状不稳定遗传，自交后代发生性状分离。 （3）生物体在形成生殖细胞（______）时，成对的遗传因子彼此分离，分别进入不同的配子中。配子中只含每对遗传因子中的一个。 （4）受精时，雌雄配子的结合是的。 2、观察遗传分析图解图1-5 思考： F1形成的雌雄配子种类、比值都相等。两种雌配子和两种雄配子结合机会______，因此F2便有了____、_____、_____三种基因组合，比例为_______ ，在性状上则近于高：矮=________。 [记忆节节清] 性状：生物体形态特征和生理特征的总称 相对性状：一种生物的同一性状的不同表现类型。 显性性状：具有相对性状的亲本杂交，F1显现出来的性状。 隐性性状：具有相对性状的亲本杂交，F1不显现出来的性状。 性状分离：杂种的自交后代中，同时出现显性性状和隐性性状的现象。 孟德尔对分离现象的解释 1、生物的性状是由遗传因子决定的。遗传因子不融合、不消失。 2、体细胞中遗传因子是成对存在的
