以y结尾的专有名词,或元音字母+y 结尾的名词变复数时,直接加s变复数:
如: two Marys the Henrys monkey---monkeys holiday---holidays
单元音:[e] [ae] [a:] [כ] [כ:] [۸] [3:] [ə] [i] [i:] [u] [u:]
双元音:[ei] [ai] [כi] [əu] [au] [εə] [iə] [uə]
可以根据词义或在句子中充当的成分来判断它的词性,也可多记单词
不可数名词没有复数形式,如:coffee,我们不能说a coffee,要说a cup of coffee.
表示限定时,比如:The coffee is delicious.这里的coffee可以是前文提到的.
