《现在完成时中since和for的用法》知识讲解
《现在完成时中s i n c e和f o r的用法》《现在完成时中since和for的用法》微课讲课稿一、引入新课同学们好，本节课我们主要学习现在完成时中since和for的用法二、学习for的用法首先，我们来看两个句子Number OneI came to this school last week. 我上周六到这所学校Number TwoI have been in the new school for a week. 我到这所新学校已经一周了我们来看一下，第一句中的last week用于一般过去时的句子，第二句中的for a week用于现在完成时的句子。
a week 是一个时间段,因此我们用“for+时间段”来表达一段时间。
那同学们看一下，如果我们把第一句话中的last week 改成last year，那么第二句话中的for a week该改成什么呢？对，应该变成for a year.三、学习since的用法接下来，我们再看两个句子Number OneLily left home last Friday. 丽丽上周五离开家Number TwoLily has been away from home since last Friday. 丽丽自从上周五已离开家我们来看一下，第一句中的last Friday是过去的一个时间点，因此这句话用一般过去时表达，而第二句中since last Friday 用在现在完成时的句子中，last Friday 是一个过去的时间点，因此我们用“since +时间点”来表达一段时间它有三个具体用法，我们来详细学习一下1、since+过去一个时间点，如具体的年月、星期、小时。
eg：1990、last night、half past six我们来看一个例句：I have been here since 1990. 我自1990年以来一直在这里1990是过去的一个时间点，since 1990, 就是since+过去一个时间点来表达一段时间的第一个用法2、since+一段时间+ago，表示“自···时间前开始至今”我们来看一个例句：He has been here since five years ago. 他在这儿已经有5年了five years 是一段时间，since后不能直接跟时间段，但后面再跟ago是可以的，因此since five years ago 就是since+时间段+ago来表达一段时间的第二个用法3、since+一般过去时从句我们来看两个例句Number OneMany things have changed since you left. 自从你走后许多事情发生了变化“you left”是一个一般过去时从句。

现在完成时中for和since的用法
180学习版■文/吕淑霞教学目标：理解圆柱侧面积的含义，掌握圆柱侧面积的计算方法，会正确计算圆柱的侧面积，并能解决一些实际问题。
通过实践操作，在学生理解圆柱的侧面积的含义的同时，培养学生的理解能力和探索意识。
适用对象：小学六年级下的学生。
设计思路：学习内容和学习目标展示使学生了解本课的学习重点，通过图片寻找哪些物体是圆柱，联系生活思考：还有哪些物体是圆柱？说一说：圆柱有几个面？各有什么特点？完成填空习题，巩固知识。
思考：如何求出圆柱的侧面积？通过图片的展示理解怎么求圆柱的侧面积。
教学过程：一、片头（30秒以内） 通过图片让学生感知圆柱的特点，并说说在生活中有哪15″；些常见的圆柱？二、正文讲解（8分钟左右）1.观察圆柱，说一说：圆柱有几个面？各有什么特点？圆柱的上、下两个面叫做底面。
它们是完全相同的两个圆。
圆柱有一个曲面，叫做侧面。
圆柱两底之间的距离叫做高（圆柱的高有无数条）。
二、正文讲解（8分钟左右）2.巩固复习新知：1.圆柱有（）个底面，它们是（）的圆。
圆柱的侧面是一个（ ）面；2.圆柱两个底面之间的（）是圆柱的高，圆柱的高可以画（）条。
它们的长度（）；3.探究：如何求圆柱的侧面积 出示习题一种圆柱形罐头盒,侧面有一张商标纸(如图),如何求商标纸的面积呢?思考：怎样求出圆柱的侧面积？圆柱的侧面展开后是长方形。
小组讨论：这个长方形的长和宽与圆柱有什么关系呢？出示圆柱的展开图，长方形的长展开后变成圆柱的底面周长，长方形的宽是圆柱的高。
长方形的面积=长×宽。
圆柱的侧面积＝底面周长×高；追问：圆柱的侧面剪开后还能得到哪些图形？平行四边形、不规则图形、正方形什么情况下能够得到正方形？圆柱的底面周长与高相等时，圆柱的侧面展开图是一个正方形.刚才的学习我们总结了圆柱侧面积的公式，接下来通过习题检验一下学习情况。
（PPT出示习题，学生自主做题）出示例题：求下面罐头盒商标纸的面积。
（接缝处忽略不计）（单位：厘米）（PPT出示例题图片）根据公式：侧面积=底面周长×高12×3.14×10 =37.68×10＝376.8（平方厘米）答：商标纸的面积是376.8平方厘米。
