It has gone hand in hand with radio, television and other media.People react to ads in different ways. Some think ads are useful and help consumersmake informed choices while others accuse companies of using ads to mislead us. Companies can influence customers’ choices by introducing a brand name and by associating products with customers’ needs. There are so many ads for customers that advertisers must try to get their message across by appealing to their emotions.Ads help companies and customers in all kinds of ways. They can help companies increase sales . At the same time , they help customers choose among all the available products. In fact, truthful ads provide good information,and help customers compare feathers, functions and costs. Some governments name a famous person as their spokesman or spokeswoman to make people awareof their social problems and policies.Customers should protect themselves by keeping an eye out for bad ads, telling false information from real facts and making good choices.II Lead-in1 what product do they persuade you to buy?2 what information about product can you get?3 How is the information conveyed?4 What are the skills of making good ads?III Reading1 How do the ad-makers create a positive image of the product they are promoting?2 How do ad-makers choose a name for the product?3 What kind of slogans should be used to make the consumers to form a positive image?

2. 数字8的加法运算1.让孩子们分组，每组选取一个代表作为加法的开始。

2.教师出示数字8和另一个数字，让代表出声说出两个数字的和。

3.每组依次进行加法运算，记录运算结果并进行核对。

4.鼓励孩子们自己尝试加法运算，并提醒关注运算过程中的小细节。

3. 数字8的减法运算1.让孩子们分组，每组选取一个代表作为减法的开始。

2.出示一个数字8和另一个小于8的数字，让代表出声说出两个数字的差。

3.每组依次进行减法运算，记录运算结果并进行核对。

4.鼓励孩子们自己尝试减法运算，并提醒关注运算过程中的小细节。

三、教学方法本课采用兴趣导入、小组讨论、实物操作等多种教学方法，让孩子们充分参与，积极思考，提高学习兴趣。

四、教学过程1. 兴趣导入教师展示一些生活中常见的具有数字意义的物品，如笔、纸、板擦等，引导孩子们认识数字，并提出数字8。

2. 认识数字8教师通过展示教具、实物等方式，让孩子们认识数字8，并学会用生活中的实物表示数字8。
