12、 ; yourTyour; his/her/itsTtheir.b名词性物主代词：minetours;yours tyours; his/hers/its ttheirs.3be动词：am is变为are。 如：Im a student.tWe are students.4 不定冠词a an表示“一个”，只能用在单数句中，当变成复数句时，一定要把 或改为some/any。 如：He is a boy. t They are (some) boys.5.普通单数名词要变为复数形式。如口：It is a cat. f They are cats.6.指示代词 由单变复。即this变为these;t

15、this that该咋办，these those替代它。he she it要变啥，全部变they就行了。I要变we别落下，名词后面把s/es加。名前冠词去掉它，其余成分原样加。把单数句子改为复数句子的规则一、 人称代词主格单数变成相应的人称代词主格复数，即I f we;you f you;she,he,it f they。如：She is a girl. f They are girls.二、am, is变为are。如：Im a student. f We are students.三、 不定冠词a, an要去掉固定搭配除外。如：He is a boy. f They are boys.四、
