7年级英语语法(第1篇)

  1. 用基数词+序数词表示:

  分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子,序数词表示分母。如:

  The centimeter is one-tenth of the decimeter or one-hundredth of the meter. 厘米是分米的十分之一,或者说是米的百分之一。

  However, the number of the boys will be less than a third of the girls in the class. 但是班里男生的人数将比女生的三分之一更少。

  *从以上例子可以看出:分子为1时,既可以用 one,也可用a。

  2. 如果分子大于1,分母则要用复数形式。如:

  三分之一 one-third;三分之二 two-thirds

  3. 二分之一不能说 a(one) second,而要说 a(one) half。

  四分之一和四分之三可以说 a(one) fourth 和 three-fourths,但常用 a quarter 和 three quarters 表示。

  4. 分数修饰的名词在句子中作主语时,谓语动词是用单数还是复数取决于名词,即与名词保持一致。如:

  Only one-fifth of air consists of oxygen. 氧气只占空气的五分之一。

  About two thirds of the students are going to attend the meeting. 大约三分之二的学生都将参加会议。

  5. 带分数的表示:

  所谓带分数,实际上是整数+分数,表达时分而述之,只是整数部分与分数部分要用连词 and 连接。如:

  You should finish the work within one and a fourth hours. 你应在1小时25分钟内完成工作。

  6. 分数常和of 连用,作主语或宾语,但分数也可以不带of 短语直接作主语或宾语。例如:

  In U.S., two-thirds continue to support death penalty. 在美国,三分之二的人仍然支持死刑。

  一、七年级英语语法--词法

  (一)名词

  1.名词的数

  我们知道名词可以分为可数名词和不可数名词,而不可数名词它没有复数形式,但可数名词却有单数和复数之分,复数的构成如下:
