who作主语是单数还是复数
who作主语时,be动词用is还是are?~?
who作主语时,be动词用is还是are?~?
都可以你听到好多人,你就问 are只听到一个,就问 is 阿,没问题的考试的时候,后面一般都有回答,那就按回答走吧,单数就是is,复数就是are
whoit is改为复数句?
正确语序:
Who is it?(改为复数句)
Who are they?
本题考查名词的复数形式。本题it的复数形式为they。主语变为they,动词要相应的改变。they对应的be动词是are。本题应该改为:Who are they?
又如:
what is it?改为复数句子
What are they?
句式:特殊疑问词 一般疑问句?
句子译文:它是什么?
变复数句,主要是变名词、人称代词,动词随主语发生变化。
此句的“it”为单数,故变为复数they。主语变成they,故be动词也由单数is变成复数are。what疑问词不变
单数句和复数句:
口诀:单数句子变,变化规则要记住。名词代词要变化,am, is要变are。
this, that变成啥,these, those来替它。he, she, it要变啥,全部变they不用怕。
I要变we莫落下,名词后面把s/es加。名前冠词去掉它,其余成分原样加。
具体注意下面的六要素:
1.单数主格人称代词要变成相应的复数主格人称代词,即I→we you→you she, he, it→they。如: She is a girl.→They are girls.
2. am, is要变为are。如: I‘m a student. →We are students.
3.不定冠词a, an要去掉。如: He is a boy. →They are boys.
4.普通单数名词要变为复数形式。如: It is a cat. →They are cats.
5.指示代词this, that要变为these, those。如: This is a book.→These are books.
6. 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.
