鲁教版中考英语作文必背范文【一】

(一)比较大小,探索方法

1.小组合作,探究方法

师提出:要想知道哪个国家的陆地面积最大,哪个国家的陆地面积最小,怎么办?你想怎样比较?请在小组内说一说你的比较方法。

2.全班交流,方法

师组织学生进行全班交流,学生可能根据数位的多少来比较,可能根据分级来比较,也可能根据数的组成来比较,还可能借助一个标准数来比较……。

对不同的比较方法老师都应给予鼓励与肯定,让学生体验解决问题策略的多样性。

3、优化方法

师提出:你认为哪种方法最简便,使用起来最快捷?(学生各抒已见)

4、归纳总结

师小结:我们在进行比较时就可以用同学们研究的既快捷又方便的方法。就是可以先看一看这些数分别是几位数,位数多的那个数就大,位数少的那个数就小;如果位数相同,就从最高位开始比较,最高位大的那个数就大,如果第一位相同就看一下位,以此类推。

5、巩固练习:比较下面每组中的两个数的大小

(二)、改写整万、整亿数为“万”或“亿”做单位的数

1、写数,体会改写的必要性

(1)师出示如下信息并要生写出横线上的数,在交流展示写的.结果时,先让学生起来读一读写出的数,通过读数让学生知道这两个数分别是整万数和整亿数。

接着提出:在刚才写的过程中,你有何体会?那么有没有写起来简便、读起来快捷,并且不改变原数大小的写法呢?同桌说一说你有什么好方法?

(学生可能会交流:用汉字代替阿拉伯数字)

师提出:那么我们就以“万”或“亿”为单位表示我国的陆地面积与人口总数,小组交流说一说怎样改写?

(2)全班交流

根据学生的回答,教师板书:

9600000平方千米=960万平方千米

1300000000人=13亿人

师提问:在将整万或整亿的数改写成“万”或“亿”作单位的数时,应该怎样改写?

交流后引导学生得出以下结论:

把整万数改写成以“万”为单位的数,可以先分级,再把万位后面的4个0去掉,最后添上一个“万”字。

把整亿数改写成以“亿”为单位的数,同样要先分级,再把亿位后面的8个0去掉,最后添上一个“亿”字。

2、对比观察,感受改写的简洁性。

师提问:比较两种写法,你认为哪种方法更简便?

通过对比各个等式的左右两边,学生很容易地感受到改写后的简洁性。

3、巩固练习:把下面的数改写成用“万”或“亿”作单位的数

1。 头绪分明,脉络清楚

写好记叙文,首先要头绪分明,脉络清楚,明确文章要求写什么。要对所写的事件或人物进行分析,弄清事件发生、发展一直到结束的整个过程,然后再收集选取素材。这些素材都应该跟上述五个“ W ”和一个“ H ”有关。尽管不是每篇记叙文里都必须包括这些“ W ”和“ H ”,但动笔之前,围绕五个“ W ”和“ H ”进行构思是必不可少的。

2。 突出中心,详略得当

在文章的框架确定后,对支持故事的素材的选取是很关键的。选材要注意取舍,应该从表现文章主题的需要出发,分清主次,定好详略。要突出重点,详写细述那些能表现文章主题的重要情节,略写粗述那么非关键的次要情节。面面俱到反而使情节罗列化,使人不得要领。这一点是写好记叙文要解决的一个基本问题,也需要一定的技巧。如:

One night a man came to our house and told me, "There is a family with eight children。 They have not eaten for days。" I took some food with me and went。

When I finally came to that family, I saw the faces of those little children disfigured (破坏外貌) by hunger。 There was no sorrow or sadness in their faces, just the deep pain of hunger。

I gave the rice to the mother。 She divided the rice in two, and went out, carrying half the rice。 When she came back, I asked her, "Where did you go?" she gave me this simple answer, "To my neighbors — they are hungry also!"

3。 用活语言,准确生动

记叙文要用具体的事件和生动的语言对人、事、物加以叙述。一篇好的记叙文的语言既要准确、生动,又要表现力强,这样才能把人、事描写得具体生动,其可读性才强。试比较下面一篇例文修改的前后效果。

原文:

One day Xiaoqiang was wandering away。 He was soon lost among people and traffic。 He could not find the way back home and started crying。 Just then, two young students who were passing by found him standing alone in front of a shop and crying。 They went up to Xiaoqiang and asked him what had happened。 Xiaoqiang told them how he got lost and where he lived。 The two students decided to take him home。 Mother was pleased to see Xiaoqiang come back safe and sound。 She invited the two students into the house and gave them some money, but they didn't take it。 She served them with tea but they left。

修改后:

The other day, five-year-old Xiaoqiang left home alone and wandered happily in the street。 After some time, he felt hungry so he wanted to go back home。 But he found he was lost among the crowded people and heavy traffic。 When he could not find the way home, he started and crying。 Just then, two young students who were passing by from school found him sanding crying in front of a shop。 They immediately went up to him。

"Little boy, why are you standing here crying?" they asked。

"I want Mom, I go home。" said the boy, still crying。

"Don't worry, we'll send you home。"

And they spent the next two hours looking for the boy's house。 With the help of a policeman, they finally found it。

When the worried mother saw her son come back safe and sound, she was so thankful and she invited the students into her house。 Gratefully, she offered them some money, saying it was a way to express her thanks, but the young students firmly refused it and left without even a cup of tea。
