同学们在做句型转换练习时,常见到“将单数句变成复数句“这类练习题。不少学生做这类练习时总是“顾此失彼”。那么,如何将单数句变成复数句呢?请注意以下几点:
一、将作主语的主格人称代词,由单数形式变为复数形式,即:I→we, you→you, she (he, it)→they。例如:
He is a boy. →They are boys.
二、am或is要变为are。例如:
I am a student. →We are students.
She is in Class One. →They are in Class One.
三、不定冠词a(an)要去掉。(固定搭配除外)例如:
It is a backpack. →They are backpacks.
四、可数名词单数要变为复数形式。例如:
It is a photo. →They are photos.
五、指示代词this或that要分别变为these或those。例如:
This is an English watch. →These are English watches.
That is a dictionary. →Those are dictionaries.
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/banana/orange/pear tree→apple/banana/orange/pear trees 苹果/香蕉/桔子/梨树;boy/girl student→boy/girl students等。
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?
八、此外,还须注意并不是所有的英语单数句子都可以变成复数句子。例如:
My name is Emma. 我叫艾玛。
