同学们在做句型转换练习时,一定见过不少“将单数句变成复数句”的习题吧!不少学生在做这类练习题时总会有点“顾此失彼”｡那么如何才能正确､完整地将单数句变成复数句呢?请走进“非常6+1”之单数句变复数句｡
1. 可数名词单数要变为其相应的复数形式｡例如:
I am a teacher.→We are teachers.
It is a box.→They are boxes.
2. 人称代词主格要由单数形式变为复数形式,即:I→we,you→you (you的单数形式和复数形式相同),he (she, it)→they｡例如:
I am a student.→We are students.
She is a girl.→They are girls.
3. am, is要变为are｡例如:
I am in Grade One.→We are in Grade One.
He is a teacher.→They are teachers.
4. 指示代词this和that要分别变为these或those｡例如:
This is a pencil-case.→These are pencil-cases.
That is an English car.→Those are English cars.
5. 不定冠词a/an要去掉｡例如:
It is a black cat.→They are black cats.
She is an English teacher.→They are English Teachers.
6. man或woman作定语修饰可数名词时,在整个句子变成复数句的情况下,也要变为复数形式men､women｡例如:
She is a woman doctor.→They are women doctors.
注意:在单数句变为复数句时,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,作修饰语的名词不必变化｡例如:
This is an apple tree. 这是一棵苹果树｡→These are apple trees. 这些是苹果树｡
6+1. 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都保持不变｡例如:
Who is she? 她是谁?→Who are they? 他们是谁?
He is young. 他年轻｡→They are young. 他们年轻｡
