2.1实义动词的一般现在时
主语是第三人称单数的情况
• 1.主语是第三人称单数时，谓语动词要进行必要的 变化。
陈述句的基本句型为： 主语+动词的第三人称单数+其他
谓语动词的第三人称单数有哪些变化呢？
在一般现在时中, 当主语是第 三人称单数形式时,用第三人 称单数形式,即加s或es. 具体 方法如下:
否定回答：No，主语+be+not
is+not=isn't are+not=aren‘t
注意：在作疑问句的回答时，主语要用相应的人称代词主格代替。
SUMMARY
• Be的用法口诀（talk bout it)
I用am；复数are,
is连着他（he）；她（she）它（it）。 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。
-- No, I _a__m__ Gina. 5. Her brother’s name __i_s__ John. 6. His family name __is___ Li.
