【发卷日期】2013年______月_______日 【学生姓名】__________________________一、如何把“单数句”变成“复数句”:1、 “人称代词/物主代词/反身代词的单数形式”变成相应的“人称代词/物主代词/反身代词的复数形式”。
也就是说:2、 be 动词变成相应的复数形式:am/is 变为___________,was 变为___________。
3、 不定冠词a/an 要________________________(去掉/保留),固定搭配除外。
例如:He is a boy.→They are boys.4、 指示代词:this 变为__________________,that 变为__________________。
例如:This is a book.→These are books.5、 man 和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。
也就是说,当man 和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:___________________________和___________________________。
例如:She is a woman teacher.→They are women teachers.【注意】当名词修饰名词表“性质”时,不作变化。
如:apple tree → apple trees6、 单数句变复数句时,句中的形容词、副词、定冠词、特殊疑问词、介词短语和感叹词等__________________________________________________(必须改变/保持不变)。
例如:Who is she? 她是谁?→ Who are they? 她们是谁?7、 有的英语单数句不可以变成复数句,必须根据题目的实际情况进行具体分析。
例如:My name is Kate. 我叫凯特。
