人教版新目标初中英语八年级上册How do you make a banana milk shake教案2篇
1. First, ... then, ... next, ... finally, ...首先，……然后，……接着，……最后，……这是英语中表达做某事的步骤的一种说法。如果步骤较多，还可以说：first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时，他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词，同是“多少”，但用法不同。请看：how many修饰可数名词复数，how much修饰不可数名词。但在用法上，同学们常犯如下错误：1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many，much是形容词，常修饰名词作定语，故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时，谓语动词用单数。how many与how much的区别可简记为：前how many：问“多少”，复数名词后面跑；how much问“多少”，不可数名词单数好。前者答语用基数词，后者答语用数量关系。

语文下册教案找春天
图文对照，读中感悟1.学习第1、2自然段。师：要去野外找春天了，课文中的小朋友现在是怀着什么样的心情呢？（高兴的、急切的、激动的）请你也带着这样的心情读一读第一、二自然段吧？自由读。指名读本段，读后评价悟出应把“脱”、“冲”、“奔”重读才能更加体现出孩子们找春天的迫切心情。2.请大家自由读第3 ~7自然段，想一想，作者把春天想象成什么了（一个害羞的小姑娘）。这个害羞的小姑娘，遮遮掩掩、躲躲藏藏的，不想让人们发现她。可是细心的小朋友还是找到了她。这些小朋友都在哪找到她了？你知道吗？从书中找到有关的句子再读一读。（学生边画、边读。）小草从地下探出头来，那是春天的眉毛吧？早开的野花一朵两朵，那是春天的眼睛吧？树林吐出点点嫩芽，那是春天的音符吧？解冻的小溪丁丁咚咚，那是春天的琴声吧？

首先请学生分析：过B、C作梯形ABCD的高，将梯形分割成两个直角三角形和一个矩形来解．教师可请一名同学上黑板板书，其他学生笔答此题．教师在巡视中为个别学生解开疑点，查漏补缺．解：作BE⊥AD，CF⊥AD，垂足分别为E、F，则BE=23m．在Rt△ABE中，∴AB=2BE=46(m)．∴FD=CF=23(m)．答：斜坡AB长46m，坡角α等于30°，坝底宽AD约为68.8m．引导全体同学通过评价黑板上的板演，总结解坡度问题需要注意的问题：①适当添加辅助线，将梯形分割为直角三角形和矩形．③计算中尽量选择较简便、直接的关系式加以计算．三、课堂小结：请学生总结：解直角三角形时，运用直角三角形有关知识，通过数值计算，去求出图形中的某些边的长度或角的大小．在分析问题时，最好画出几何图形，按照图中的边角之间的关系进行计算．这样可以帮助思考、防止出错．四、布置作业
北师大初中九年级数学下册利用三角函数测高2教案
问题2、如何用测角仪测量一个低处物体的俯角呢?和测量仰角的步骤是一样的，只不过测量俯角时，转动度盘，使度盘的直径对准低处的目标，记下此时铅垂线所指的度数，同样根据“同角的余角相等”，铅垂线所指的度数就是低处的俯角.活动三：测量底部可以到达的物体的高度.“底部可以到达”，就是在地面上可以无障碍地直接测得测点与被测物体底部之间的距离.要测旗杆MN的高度，可按下列步骤进行：(如下图)1.在测点A处安置测倾器(即测角仪)，测得M的仰角∠MCE=α.2.量出测点A到物体底部N的水平距离AN＝l.3.量出测倾器(即测角仪)的高度AC＝a(即顶线PQ成水平位置时，它与地面的距离).根据测量数据，就能求出物体MN的高度.在Rt△MEC中，∠MCE=α，AN=EC=l，所以tanα= ，即ME=tana·EC＝l·tanα.又因为NE＝AC＝a，所以MN＝ME+EN＝l·tanα+a.

北师大初中九年级数学下册商品利润最大问题1教案
(2)问销售该商品第几天时，当天销售利润最大，最大利润是多少？解析：(1)分1≤x＜50和50≤x≤90两种情况进行讨论，利用利润＝每件的利润×销售的件数，即可求得函数的解析式；(2)利用(1)得到的两个解析式，结合二次函数与一次函数的性质分别求得最值，然后两种情况下取最大的即可．解：(1)当1≤x＜50时，y＝(200－2x)(x＋40－30)＝－2x2＋180x＋2000；当50≤x≤90时，y＝(200－2x)(90－30)＝－120x＋12000.综上所述，y＝－2x2＋180x＋2000（1≤x＜50），－120x＋12000（50≤x≤90）；(2)当1≤x＜50时，y＝－2x2＋180x＋2000，二次函数开口向下，对称轴为x＝45，当x＝45时，y最大＝－2×452＋180×45＋2000＝6050；当50≤x≤90时，y＝－120x＋12000，y随x的增大而减小，当x＝50时，y最大＝6000.综上所述，销售该商品第45天时，当天销售利润最大，最大利润是6050元．方法总结：本题考查了二次函数的应用，读懂表格信息、理解利润的计算方法，即利润＝每件的利润×销售的件数，是解决问题的关键．

北师大初中九年级数学下册切线的判定及三角形的内切圆教案
解析：(1)连接BI，根据I是△ABC的内心，得出∠1＝∠2，∠3＝∠4，再根据∠BIE＝∠1＋∠3，∠IBE＝∠5＋∠4，而∠5＝∠1＝∠2，得出∠BIE＝∠IBE，即可证出IE＝BE；(2)由三角形的内心，得到角平分线，根据等腰三角形的性质得到边相等，由等量代换得到四条边都相等，推出四边形是菱形．解：(1)BE＝IE.理由如下：如图①，连接BI，∵I是△ABC的内心，∴∠1＝∠2，∠3＝∠4.∵∠BIE＝∠1＋∠3，∠IBE＝∠5＋∠4，而∠5＝∠1＝∠2，∴∠BIE＝∠IBE，∴BE＝IE；(2)四边形BECI是菱形．证明如下：∵∠BED＝∠CED＝60°，∴∠ABC＝∠ACB＝60°，∴BE＝CE.∵I是△ABC的内心，∴∠4＝12∠ABC＝30°，∠ICD＝12∠ACB＝30°，∴∠4＝∠ICD，∴BI＝IC.由(1)证得IE＝BE，∴BE＝CE＝BI＝IC，∴四边形BECI是菱形．方法总结：解决本题要掌握三角形的内心的性质，以及圆周角定理．
