名词的重要考点

名词的复数变化

名词复数的规则变化是:

①一般在词尾加“s”如:desk+s [-ks] bag+s [-gz] bed+s[-dz] hat+s [-ts]

②以字母 s、x、sh、ch结尾的名词变复数，通常在词尾加“es”，如：bus+es [-iz] box+es [-iz] brush+es [-iz] watch + es [-iz]

③以字母o结尾的名词变复数, 一般在词尾加“s”,也有加es的,如:photo+s [-z] tomato+es [-z]

④以f或fe结尾的名词一般变f或fe为v再加es,例如:

knife─knives[-vz] leaf─leaves [-vz]

⑤以辅音字母加y结尾的名词,变复数时改y为i,再加es, 如: baby ─ babies factory─factories
