16、、一般现在时分类：1 . 一般现在时态分为be动词的一般现在时。1） be动词包括am, is, are.中文为"是"，这三个词的用法要随着主语的变化 而变化。"am"用于第一人称单数（I） ; "is"用于第三人称单数（he, she, it）; "are ”用于第一人称复数（we）,第二人称单数和复数（you）,第三人称复数（they）。 可以记住以下顺口溜：am管"我"，is管"，她，它，他", are管"大家"。一般疑问句和否定句：把be动词"am

17、, is, are"放在句首，回答时也要使用be动 词；变为否定何时，把表示否定的not放在"am is are”的后面，其中可以简写为： is not- isn't ; are not- aren't; am not 没有简写形式。注意： 如果 are not, is not 放在旬尾时，不能使用简写，必须写出整个单词。.Am I a teacher? Yes, I am. (No, I am not.) Are you his friend? Yes, you are. (No, you are not.)Is she a nurse? Yes, she

18、 is. (No, she is not.)否定旬为：I am not a teacher. You are not his friend. She is not a nurse.2)实义动词的一般现在时如果句子的动词不是be动词"am is are"而是其他实义动词，疑问旬和否定句要借助于助动词"do"或者"does",也就是说be动词和 实义动词原形不能同时使用。这里的"do", "does"本身没有什么意义，只是帮助构成疑问句和否定句.一般疑问句读时必须用降调."do"

19、和"does”的使用要随 着人称的变化而变化。请看下面两组句子，注意区分他们的共同点和不同点。I go to school every day.I don't go to school every day.He goes to school every day.He doesn't go to school every day.Do you go to school every day?Does he go to school every day?Yes, I do. (No, I don't)Yes, he does. (No, he doesn't

20、)当主语是第三人称单数时，肯定何为：主语+动词的s形式+宾语否定何为：主语+助动词doesn't+动词原形+宾语疑问何为：Does+主语+动词原形+宾语肯定回答和否定回答也要使用助动词does.注：1)第三人称单数用了 does后面就不用动词的s形式了，而用动词原形.2)变为疑问句，要在旬首加"do"变为否定句,要在动词前面加"do not",可以简 写为"don't".课堂练习一、把下列句子改成一般疑问句并做肯定、否定回答。1. I usually get up at six o 0 clock Yes, . /No
