15、.2. 物主代词 由单数变成相对应的复数，即a， 形容词性物主代词： my our ; your your; his/her/its their.b 名词性物主代词： mine ours;yours yours; his/hers/its theirs.3 be 动词 ：am is变为 are 。如： im a student. we 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aan 去掉或改为some/any。如： he is a boy. they are (some) boys. 5 普通单数名词要变为复数形式。如： it

16、is a cat. 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. these are books.7 man woman 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. they are men doctors.this is an apple tree. they 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. th

17、ese 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. 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？ 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 要变化， am is 要变 are 。this that 该咋办， these those 替代它。 he she it 要变啥，全部变 they 就行了。 i

18、 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 we;you you;she,he,it they 。 如： she is a girl. they are girls. 二、am, is 变为 are 。如： im a student. we are students. 三、不定冠词a, an 要去掉固定搭配除外。如：he is a boy. they are boys. 四、可数名词单数要变为复数形式。如：it is a cat. they are cats. 五、指示代词th

19、is, that 变为these, those。如： this is a book. these are books. 六、 man或 woman修饰可数名词时， 在整个句子变成复数的情况下，它们也变为复数形式men, women。例如：she is a woman teacher. they are women teachers. 注意：普通单数可数名词要变为复数形式，但当名词修饰名词表示“性质”时不作变化。例如：apple tree apple trees boy student boy students that s an apple tree. they are apple trees

20、. 七、单数句变复数句时，句中的形容词、定冠词、副词、疑问词、介词短语和感叹词等保持不变。例如：who is she? 她是谁？who are they? 她们是谁？但是，在英语中有些单数句不能变为复数句，如：lily is fourteen.(莉莉 十四岁。 )his name is jim.(他的名字叫吉姆。)等。5）将以下单复数句进行转换1 this is a knife. _ 2 that is a tomato. _ 3 that child is very good._ 4 . these are mice. _ 4 / 4 5 those are children. _ 6. she is a girl 。_are_ 7. is the dictionary on hte
