    区分宾语从句、定于从句和状语从句宾语从句和状语从句,都叫做主从复合句。宾语从句主要是中考必考的,是初中阶段必掌握的从句,宾语从句主要是掌握三要素,所谓宾语从句,就是宾语在主从复合句当中充当宾语的一个句子,叫做宾语从句。主句的谓语动词是及物动词,后面如果是词或者是短语的话,是简单句,如果是句子的话,肯定是宾语从句。I know that he good at English.就是宾语从句,三要素,一要素是要注意连词,连词一共学了三类连词,一类连词是that口语当中可以省略,就像刚才说的那一句,I hear he is good at English.还有疑问代词、疑问副词,how where when,疑问代词、疑问副词。还有一类连词weather是否的意思,不是状语从句当中的如果,这一定要和如果区分开,这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序,要用陈述举语序。比如说你家有几口人,我们都说How many people are there in you family?但是这是简单句,一旦说成宾语从句,你可以告诉我你家有几口人吗?Could you tell me how many people there are in you family ?

But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them.

    人教A版高中数学必修一单调性与最大(小)值教学设计(2)

    《函数的单调性与最大(小)值》是高中数学新教材第一册第三章第2节的内容。在此之前,学生已学习了函数的概念、定义域、值域及表示法,这为过渡到本节的学习起着铺垫作用。学生在初中已经学习了一次函数、二次函数、反比例函数的图象,在此基础上学生对增减性有一个初步的感性认识,所以本节课是学生数学思想的一次重要提高。函数单调性是函数概念的延续和拓展,又是后续研究指数函数、对数函数等内容的基础,对进一步研究闭区间上的连续函数最大值和最小值的求法和实际应用,对解决各种数学问题有着广泛作用。课程目标1、理解增函数、减函数 的概念及函数单调性的定义;2、会根据单调定义证明函数单调性;3、理解函数的最大(小)值及其几何意义;4、学会运用函数图象理解和研究函数的性质.数学学科素养
