10、week（每周）, every month（每月）, every term（每学期）, every year（每年）, once a week （一周一次），twice a year（一年两次）等表示时间的词连用。三、第三人称单数问题一般现在时中，当主语是第三人称单数时，即常在动词原形后加-s 或-es。四、一般现在时分类：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
11、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，is，are“ 放在句首,回答时也要使用 be 动词；变为否定句时,把表示否定的 not 放在 “am is are“ 的后面, 其中可以简写为：is not- isnt ；are not- arent；am not 没有简写形式。注意：如果 are not, is not 放在句尾时，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
12、 you his friend? Yes, you are. (No, you are not.)Is she a nurse? Yes, she is. (No, she is not.)否定句为：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, 疑问句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
13、句和否定句. 一般疑问句读时必须用降调.“do“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 dont go to school every day.He goes to school every day. -He doesnt go to school every day.Do you go to school every day? -Does he go to school every day?Yes, I do. (No, I dont) -Yes, he does. (No, h
14、e doesnt)当主语是第三人称单数时，肯定句为：主语+动词的 s 形式+宾语 否定句为：主语+助动词 doesnt+动词原形+宾语疑问句为：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,要在句首加“do“ ; 变为否定句, 要在动词前面加“do not“, 可以简写为 “dont“.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。1I usually get up at six oclock.?Yes, . /No, .2.
