用英语介绍我的朋友作文四年级【一】
Dear Sir,
I am writing to seek your advice regarding which subject I should choose as my major, history or computer science. I am studying in the last year in high school now.
Next year, I hope that I will be able to enroll in your college. I began to take a special interest in history when I was a primary school student. I can still remember the historical stories my teachers told in class, so I was wondering if I should continue to study in your college. However, several days age, one of my friends told me that computer science is more popular nowadays.
As a matter of fact, many jobs need IT skills. I was advised that it’s more important to find a job than merely to satisfy personal interest. Therefore, it is now very hard for me to decide which subject I should choose. Must I give up my favorite subject and take employment need as a priority? I would be more than grateful to you if could tell me your advice about this. Your early reply would be highly appreciated.
Yours faithfully
Wang Rutao

一、复习
1．复习比较两个数的大小。
师：我们已经学了怎样比较亿以内数的大小，谁来说一说比较大小的方法。（指名1、2个学生回答）
师让学生自己完整的总结：首先要看数位是否相同，相同的数位就要从最高位比起，如果不能比较出来，就一位一位往下比，直到比出大小为止。如果数位不相同，就看哪一个数的数位多那个数就大。
2．复习把整万的数改写成用万作单位的数。
1100000＝110万 1210000＝121万 720000＝72万
师：要写成以万作单位的数就要把万后面的零去掉，要加上一个万字。
3．做一做练习 学生独立完成，全班核对。
二、复习求近似数的方法
1．让学生表演地球与太阳（课本例6）。
2．师：大约130万个是一个什么数？
生：是一个大概数，近似数。
师：求一个近似数要用什么方法？
生：四舍五入。
3．1275610000＝1万 13890001390000＝139万
13000＝13千 ＝1389千
① 师：我们要省略万后面的尾数应该怎么做？
生：首先找出万位，再看千位上的数是否满5，不满5就四舍，满5就五入，然后在把万后面的数改写成零或加一个万字。
② 请同学思考：如果是省略千、百后面的尾数又该怎么办呢？
做练习15页的做一做，然后在小组内交流。请小组派代表来汇报。
生总结：省略哪一个数位上的数要先找出那个数位，然后看到右边下一位是否满5决定四舍五入，但必须在后面加上省略那一数位上的计数单位。
三、巩固练习
1．第4题 由师生对答哪些是近似数，哪些是准确数。
2．第5题 由学生自己独立完成，然后开火车的形式校正，并要求说明过程。
3．第7题 由老师提示，讲解题意，然后让学生独立完成，同桌互对。投影校对，并让学生提出质疑。
4．第8题 学生独立完成，拿学生的课本投影校对，并请学生说明理由。
四、课堂小结
让学生说说这节课的体会，并答解疑难问题。

Such is sons’ nature; I really do not know how to express my thanks to you. However, I can imagine, on the day 18 years ago, when you gave birth to me, what a complex feeling you had. In the past few years, every day you struggle me up in the morning and prepare breakfast for me, then in the afternoon, you always welcome your only son with delicious foods after a day‘s hard work. Now your son has been 18 and will go to university soon, like a bird is leaving its parents. Nevertheless, your footprints on my heart will never ever fade and I love you mum!
your son
