一、加减乘除表示法 二、分数表示法 三、数学符号的表达 四、分数表示法 五、百分数表示法 六、数量表示法
一、加减乘除表示法 1. “加”用plus，and或add表示；“等于” 用is，make，equal等词表示。 2+3=? 可表示为： How much is two plus three? 2+3=5 Two plus three is five． Two and three is equal to five． Two and three make five． Two added to three equals five． If we add two to/and three, we get five．
四、用“基数词＋介词＋基数词”表 示
• 借助介词表示分数，介词前的数词是分子，介词 后的数词是分母。 • 例如： • Ninety-nine people out of a hundred，if they were asked who first found America， would answer Clumbus． 如果要问是谁首先发现美洲，一百个人中有九十 九个（百分之九十九）将回答是哥伦布。 • 这种结构中的介词主要有in，out of，of以及to
•
5. 表示“比·· ·大（或）几倍”的说 法。 This room is two times bigger than that one． 这个房间比那个（房间）大两倍。 The dictionary is four times thicker than that book． 这本词典比那本书厚四倍。 My age is two times older than his． 我的年龄比他大两倍。
• 4. “除”用divide的过去分词形式表示 • 16÷4=? How much is sixteen divided by four? • 16÷4＝4 • Sixteen divided by four is four． • Sixteen divided by four equals/gives/makes four． • 十六除以四等于四。
牛津九年级下册unit4知识点
牛津九年级下册unit4知识点牛津九年级下册的第四个单元主要涵盖了一些关于数字和数学方面的知识点。
在这个单元中，我们将学习如何用英语来表达数字，进行简单的数学计算，同时也会了解一些与数学相关的名词和概念。
本文将对此单元的知识点进行探讨和总结。
首先，我们从数字的表示和读法开始。
在英语中，数字由0到9这几个基本的数字字符组成，通过组合这些数字字符，我们可以得到任意的整数。
例如，数字10可以被表示为"ten"，数字23可以被表示为"twenty-three"。
另外，当数字超过20的时候，我们通常会使用基数词和序数词的形式来表达。
例如，数字30可以被表示为"thirty"，而数字31则可以被表示为"thirty-first"。
在进行数学计算的时候，我们需要掌握一些基本的运算符号和方法。
加号"+"可以表示两个数的相加，减号"-"可以表示两个数的相减，乘号"*"可以表示两个数的相乘，而除号"/"则可以表示两个数的相除。
此外，我们还可以用括号"()"来改变计算的优先级。
例如，表达式3+4*5可以通过括号的运用变为3+(4*5)，得到结果23。
这些基本的数学符号和方法将在我们的日常生活和学习中经常用到。
除了了解数字和数学运算的基本知识，我们还需要了解一些与数学相关的名词和概念。
例如，我们常常会听到"平方"和"立方"这样的术语。
"平方"可以用来表示一个数字被自身乘以的结果，而"立方"则表示一个数字被自身乘以两次的结果。
例如，2的平方得到4，2的立方则得到8。
这些概念在几何学和代数学中都有重要的应用。
此外，我们还需要了解一些关于分数和小数的知识。
分数是用来表示一个整数除以另一个整数的结果。
英语之数学的常见口语语句
英语之数学的常见口语语句关于英语之数学的常见口语语句口语:跟“数字”有关的习语1.To be dressed up to the nines穿着非常时髦,穿得非常华丽[亦作 be dressed to death]The girls were dressed up to the nines and went to the party.姑娘们个个盛装打扮，前去赴宴。
2.one-horse town--乡村小镇。
这一短语源自美国，由小镇仅拥有一匹马而来。
由此引申，one-horse现在可以表示“极小的、简陋的、次要的.” 意思，如one-horseshow(小型展览会)。
由one组合成的习语。
而又毫无“一” 这一含义的习语还有：(1) He was one too many for me.我不是他的对手。
(2) Number one -- 自己。
由此而衍生to look after number one(自私，追求自己的利益)3.Two of a trade did never agree -- 同行相轻。
这是一句古老的谚语.由two组合成的习语还有：(1) when two Fridays come together.“永远不”的遁词。
(2) The two eyes of Greece.希腊古代的两座城市“雅典”和“斯巴达”。
4.Three sheets in the wind -- 酩酊大醉。
sheet 的一个词义是“系在帆下角的金属环上的帆脚索”。
如果帆脚索没有系扣住时，船帆可以任意随风飘扬。
船员们称之为in the wind。
Asheet in the wind由此成为船员们一句口头语言，表示tipsy(微醉)。
Three sheets in the wind自然是大醉特醉了。
由three组合成的习语还有：Three score and ten --古稀之年。
score在英语中是“二十”的意思。
