15、为 some/any 。 如：he is a boy. f they are (some) boys.5 .普通单数名词要变为复数形式。如：it is a cat. 一 they are cats.6 .指示代词 由单变复。即 this 变为 these ; that 变成 those。如：this is a book. 一 these are books.7. manwoman作定语修饰可数名词时,要在数上与被修饰名词保持一致。但其他名词修饰名词表示性质时,不作变化。如： he is a man doctor. fthey are men doctors. this is an apple

16、tree. fthey are apple trees.8 . 一般情况下，形容词性物主代词在单数句变成复数句时不变。如：this is my pen. 一these are my pens.9 .当句中形容词性物主代词与句中的主语一致时，该物主代词应随主语人称的变化而变化，仍要保持一致。如：he likes his bike. 一they like their bikes.10 .单数句变成复数句时，句式不能变。即单数句是疑问句时，变成复数句时仍然是疑问句。如：whats this ? 一 what are these ?记住单数句变复数句的口诀。单数句子变复数， 变化规则要记住。名词代词要
