问题探究
▲含有be动词的一般疑问句
Is
that
your
backpack？那是你的双肩背包吗？
这是一个含有be动词的一般疑问句。在含有am，is，are的一般疑问句中，要把am，is，are放在句首位置，句末用标点符号问号，读时用升调。回答时通常用“Yes”或“No”来作答。肯定回答结构为Yes，主语＋be。否定结构为：No，主语＋be
not。其中主语为和一般疑问句相对应的人称代词的主格。
▲—Is
that
your
book？——那是你的书吗？
—Yes，it
is
mine.——是的，它是我的。
名词性物主代词常用来避免和前面提到的名词重复，单独使用。名词性物主代词＝形容词性物主代词＋名词。为避免重复使用名词，有时可用“名词性物主代词”来代替“形容词性物主代词＋名词”的形式。
