第1讲:名词
名词当然是大家都很熟悉的了,我们吃的food,喝的drinks,穿的clothes 都是名词。It is easy, right? 但是你可能被名词的单复数变化、名词作定语以及名词所有格等问题搞得糊里糊涂的,到底该怎么用呢?OK,follow me。
First, 名词复数的特殊变化。
普通名词的复数我们知道是直接加-s或 -es,可是偏偏有一些名词不听话,变化不规则。这些小调皮是:
a. class, box, watch, brush等词以 s, x, ch, sh, 结尾,复数要加-es;
b. story, factory 等以"辅音字母+y"结尾的词复数要先将-y 变成-i再加-es;
c. knife, wife, life等以-f 或-fe结尾的词一般先将-f或-fe变为-v, 再加-es;
d. 以-o结尾的名词,一般来说,末尾是"元音字母+o" 的词加-s,我们学过的有radio,zoo。末尾是"辅音字母+o"的词,变复数加-es。如:tomato, hero, potato,当然其中的piano 和photo,又是一个例外,他们的结尾只能加-s。
