六上 U2 What a day 专题6 be动词的用法及练习 be 动词在一般现在时和一般过去时中的用法,我们可以用两个口诀来记忆。 一、一般现在时中,be动词的用法口诀: 我用 am, 你用 are, is 连着他, 她,它; 单数名词用 is,复数名词全用 are。 变疑问,往前提,句末问号莫丢弃。 变否定，更容易, be 后 not 莫忘记。 疑问否定任你变,句首大写莫迟疑。 二、一般过去时中,be动词的用法口诀: I 用 was, you 用 were, was 连着他, 她, 它。 单数名词用 was,复数名词全用 were。 变否定,很容易, be 后 not 莫忘记。 变疑问,往前提,句末问号莫丢弃。 特殊情况要记住, I was 变 were you。 疑问否定任你变,句首大写莫迟疑。 注意: there is/are 句型的一般过去时为 there was/were。 否定句:主语+ be动词的过去式（was/were）+ not… 一般疑问句: be 动词的过去式（Was/Were）+主语… 特殊疑问句:疑问代词/疑问副词 + was/were+主语… 小试牛刀 用 be 动词适当的词填空。 1.
