今天晚上我与妈妈一起观看了《第四届宜昌汉语言文字大赛》,在观看的`过程中我学到了很多知识,这些知识现在都还浮在我的脑海中呢!
这一次的《第四届宜昌汉语言文字大赛》主要讲了有7个地区的中小学生代表队参加的比赛,他们分别是枝江、远安、当阳、猇亭、夷陵、五峰、三峡。选手们个个满腹经纶,在初赛中闯过重重关卡,最终获得胜利,他们的知识让我佩服的五体投地。他们在比赛中一定收获的很多!除了他们收获了颇丰,我也收获了很多,问题出来瞬间,胸有成竹时,大声喊出答案,之后,暗暗高兴平时积累了一点小知识,在不确定答案时,可以查资料书……
观看完比赛,想起了德雷克斯的一句:知识是心灵的眼睛。我想:我一定要珍惜现在在学校的宝贵时间来学习,不光因为我已经是一个三年级的学生了,也是为了自己学习成绩有所进步,哎,看着自己的现状,我认为自己和他们相差甚远,我想对自己说:“雷正睿,努力,加油,用更多的知识武装自己!”

1、时态:不同的时态相对应的助动词
一般现在时:谓语动词用原形(主语为第三人称单数时,动词加s或es,变否定句、疑问句时助动词为do或does)
一般过去时:谓语动词用过去式,变否定句、疑问句时助动词为did.
现在完成时:助动词have/has+动词的过去分词
过去完成时:助动词had+动词的过去分词
一般将来时:will/begoingto+动词原形
过去将来时:would/wasorweregoingto+动词原形
现在进行时:am/is/are+动词的现在分词
过去进行时:was/were+动词的现在分词
2、语态:主动语态变为被动语态的谓语结构
一般现在时:am/is/are+动词的过去分词
一般过去时:was/were+动词的过去分词
一般将来时:willbe+动词的过去分词
情态动词:can/may/must/need等情态动词+be++动词的过去分词
3、改反意疑问句时注意hardly,never,seldom,few,little,no等词表达的'是否定意义,变反意疑问句时用肯定形式。
4、在合并句子时,有些连词如notonly…butalso…,neither…nor…,either…or…是就近原则,连接两个主语时动词形式取决于与动词邻近的主语。而both…and…连接两个主语时,主语是复数。
5、简单句和复合句之间的互换常见的有:
带有疑问词的宾语从句改为特殊疑问词+to+动词原形的不定式;结果状语从句so…that…改为enoughto或too…to…的简单句。
6、保持原句意思改写句子时注意时态不变。
一个较大的多位数,为了读写方便,常常把它改写成用“万”或“亿”作单位的数。有时还可以根据需要,省略这个数某一位后面的数,写成近似数。
1. 准确数:在实际生活中,为了计数的简便,可以把一个较大的数改写成以万或亿为单位的数。改写后的数是原数的准确数。 例如把 1254300000 改写成以万做单位的数是 125430 万;改写成 以亿做单位 的数 12.543 亿。
2. 近似数:根据实际需要,我们还可以把一个较大的数,省略某一位后面的尾数,用一个近似数来表示。 例如: 1302490015 省略亿后面的尾数是 13 亿。
3. 四舍五入法:要省略的尾数的最高位上的数是4 或者比4小,就把尾数去掉;如果尾数的最高位上的数是5或者比5大,就把尾数舍去,并向它的前一位进1。例如:省略 345900 万后面的尾数约是 35 万。省略 4725097420 亿后面的尾数约是 47 亿。
4. 大小比较
(1比较整数大小:比较整数的大小,位数多的那个数就大,如果位数相同,就看最高位,最高位上的数大,那个数就大;最高位上的数相同,就看下一位,哪一位上的数大那个数就大。
(2比较小数的大小:先看它们的整数部分,,整数部分大的`那个数就大;整数部分相同的,十分位上的数大的那个数就大;十分位上的数也相同的,百分位上的数大的那个数就大……
(3比较分数的大小:分母相同的分数,分子大的分数比较大;分子相同的数,分母小的分数大。分数的分母和分子都不相同的,先通分,再比较两个数的大小。
以上是为大家准备的小升初数学考试数的改写知识要点,希望对大家有所帮助。
