Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3.

    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 ?

    "Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. 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. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!欢迎你!请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢?“噢,不!”与陌生人谈话太困难了。但是这也很有意思,并且你还能交到朋友。你该怎么做呢?闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员,不是吗?”“我希望自己能认识她,你呢?“今年的雨水很多,不是吗?”反意疑问句是一种礼貌用语。为了使得谈话成功,你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧,下次在英语课上,你会发现与大家展开谈话是一件很容易的事情,不信我们来试试。)

    解析:水是生命之源,节约水资源是我们每个居民都应有的意识.题中给出假如每人浪费一点水,当人数增多时,将是一个非常惊人的数字,100万人每天浪费的水资源为1000000×0.32=320000(升).所以320000=3.2×105.故选B.方法总结:从实际问题入手让学生体会科学记数法的实际应用.题中没有直接给出数据,应先计算,再表示.探究点二:将用科学记数法表示的数转换为原数已知下列用科学记数法表示的数,写出原来的数:(1)2.01×104;(2)6.070×105.解析:(1)将2.01的小数点向右移动4位即可;(2)将6.070的小数点向右移动5位即可.解:(1)2.01×104=20100;(2)6.070×105=607000.方法总结:将科学记数法a×10n表示的数,“还原”成通常表示的数,就是把a的小数点向右移动n位所得到的数.三、板书设计借助身边熟悉的事物进一步体会大数,积累数学活动经验,发展数感、空间感,培养学生自主学习的能力.

    北师大初中数学八年级上册认识无理数2教案

    本节课中教师首先用拼图游戏引发学生学习的欲望,把课程内容通过学生的生活经验呈现出来,然后进行大胆置疑,生活中的数并不都是有理数,那它们究竟是什么数呢?从而引发了学生的好奇心,为获取新知,创设了积极的氛围.在教学中,不要盲目的抢时间,让学生能够充分的思考与操作.(二)化抽象为具体常言道:“数学是锻炼思维的体操”,数学教师应通过一系列数学活动开启学生的思维,因此对新数的学习不能仅仅停留于感性认识,还应要求学生充分理解,并能用恰当数学语言进行解释.正是基于这个原因,在教学过程中,刻意安排了一些环节,加深对新数的理解,充分感受新数的客观存在,让学生觉得新数并不抽象.(三)强化知识间联系,注意纠错既然称之为“新数”,那它当然不是有理数,亦即不是整数,也不是分数,所以“新数”不可以用分数来表示,这为进一步学习“新数”,即第二课时教学埋下了伏笔,在教学中,要着重强调这一点:“新数”不能表示成分数,为无理数的教学奠好基.
