The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分，只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:?

You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better.

They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers!

一、 问题导学前面两节所讨论的变量,如人的身高、树的胸径、树的高度、短跑100m世界纪录和创纪录的时间等,都是数值变量,数值变量的取值为实数.其大小和运算都有实际含义.在现实生活中,人们经常需要回答一定范围内的两种现象或性质之间是否存在关联性或相互影响的问题.例如,就读不同学校是否对学生的成绩有影响,不同班级学生用于体育锻炼的时间是否有差别,吸烟是否会增加患肺癌的风险,等等,本节将要学习的独立性检验方法为我们提供了解决这类问题的方案。在讨论上述问题时,为了表述方便,我们经常会使用一种特殊的随机变量,以区别不同的现象或性质,这类随机变量称为分类变量.分类变量的取值可以用实数表示,例如,学生所在的班级可以用1,2,3等表示,男性、女性可以用1,0表示,等等.在很多时候,这些数值只作为编号使用,并没有通常的大小和运算意义,本节我们主要讨论取值于{0,1}的分类变量的关联性问题.

人教版高中语文必修1《奇妙的对联》教案2篇
3、介绍对联的历史引出本课的重点。人类历史上的第一副对联是“新年纳余庆，嘉节号长春”。出现在五代十国时期（公元964年），距离现在已经有1044年了。有着一千多年历史的对联有什么基本的特点呢？这是我们这节课学习的重点。请在座的各位当回医生，给下面这幅对联号号脉，看它对仗是否工整？上联：冬去春来千条杨柳迎风绿下联：冰消雪化梅花万朵扑鼻有什么问题，怎么改？刚才这几位同学指出了这幅对联的两个问题，也提出了两条修改意见。第一是下联少了一个字，最好是添加一个“香”字；第二是下联的“梅花万朵”与上联的“千条杨柳”是数量词对名词，名词对数量词，对仗不工整，要调整为“万朵梅花”。这样，数量词“万朵”对“千条”，名词“梅花”对“杨柳”。大家还有没有不同的看法。这样我们就可以得出对联的两个特点特点：第一个特点是上下联字数要相等（板书）。就是上联有几个字，下联也要有几个字。大家记下来，对联基本要求一，“上下联字数相等”。这个要求是很严格的，一般来说，违反这个规则就不成对联了。

人教版新课标高中物理必修1伽利略对自由落体运动的研究教案2篇
猜想：既然物体下落过程中的运动情况与物体质量无关，那么为什么在现实生活中，不同物体的落体运动，下落快慢不同呢？我们能否猜想是由于空气阻力的作用造成的呢？如果没有空气阻力将会怎样呢？学生讨论后回答.三、猜想与假说伽利略认为，自由落体是一种最简单的变速运动.他设想，最简单的变速运动的速度应该是均匀变化的.但是，速度的变化怎样才算均匀呢?他考虑了两种可能：一种是速度的变化对时间来说是均匀的，即经过相等的时间，速度的变化相等；另一种是速度的变化对位移来说是均匀的，即经过相等的位移，速度的变化相等.伽利略假设第一种方式最简单，并把这种运动叫做匀变速运动.四、实验验证实验验证是检验理论正确与否的唯一标准.任何结论和猜想都必须经过实验验证，否则不成理论.猜想或假说只有通过验证才会成为理论.所谓实验验证就是任何人，在理论条件下去操作都能到得实验结果，它具有任意性，但不是无条件的，实验是在一定条件下的验证，而与实际有区别.

人教版高中政治必修4用对立统一的观点看问题精品教案
1、重点：如何处理主次矛盾、矛盾主次方面的关系，具体问题具体分析2、难点：弄清主次矛盾、矛盾主次方面的含义四、学情分析高二学生具备了一定的抽象思维和综合分析的能力,但实践能力普遍较弱。本框所学知识理论性较强，主次矛盾和矛盾的主次方面这两个概念极易混淆，学生较难理解。而且本框内容属方法论要求，需要学生将理论与实践紧密结合，学生在运用理论分析实际问题上还比较薄弱。五、教学方法：1、探究性学习法。组织学生课后分小组进行探究性学习。在探究性学习中进行：“自主学习”、“合作学习”。让学生进行自主学习的目的是：让学生作学习的主人，“爱学、乐学”，并培养学生终身学习的能力；让学生进行合作学习的目的是：在小组分工合作中，在生生互动（ 学生与学生互动）中，促使学生克服“以自我为中心，合作精神差，实践能力弱“等不足，培养综合素质。2、理论联系实际法。关注生活，理论联系实际,学以致用。
