Step 2:知识点拨
一、一般现在时(The Simple Present Tense)
一） 什么是一般现在时？？
1.表示现在的状态：e.g. He’s twelve.
2. 表经常或习惯性的动作，常与频度副词连用。
e.g. He reads English every morning.
3.表主语具备的性格、能力和兴趣爱好等： e.g. She likes noodles.
4.普遍真理和自然规律： e.g. The moon goes around the earth.
（二) 一般现在时的时间状语——频度副词
always(一直), usually(通常),often(经常), sometimes(有时), seldom(不常),
never(从不).
副词短语：every day(每天), every morning，every+时间.
once a day(每天一次), twice a week(每周两次), three times a day.(每天三次）
three times a week(每周三次)
【小试牛刀】判断以下句子的时态。
1. He is a worker.
2. I played basketball yesterday.
3. My father goes to work by car every day.
4. Xiaoling always studies hard.
5. Jiamin sometimes plays computer games.
6. She is reading an English book.
7. My mother is going to Shanghai tomorrow.
8. You should take the medicine three times a day.
9. I am never late for school.
10. Rose usually goes shopping with her mother.
你发现了吗？
以上一般现在时的句子中，主语不同时，谓语动词一样吗？发生了什么变化呢？
(三）一般现在时的构成
主语 + be(am/is/are) + 其它 (I 用am, you 用are, is 连着 he, she ,it )
主语(第一、第二人称和复数） + 实义动词的原形 + 其它
主语(第三人称单数) + 动词三单式 （Vs）+ 其它
复习动词三单式
1） 动词三单形式变化规律
1. 一般情况下，直接在词尾加（ ） eg: work---works
2. 以x, s, o, sh, ch结尾的动词，在词尾加 ( ） eg: wash—washes watch—watches
3. 以辅音字母加y 结尾的动词，把y 变为( ) 加( ) eg:study—studies
【实战演练】：用动词的适当形式填空：
1． John ________(go) to school by bike every day.
2． Kate often __________(play) table tennis with her friends after school .
3． My mother usually ________(go) shopping and ________(buy) some vegetables .
4. He often ________(have) dinner at home.
5. Daniel and Tommy _______(be) in Class One.
6. The girl _______(teach) us English on Sundays.
7. She and I ________(take) a walk together every evening.
8.. Mike _______(like) cooking.
9. You always _______(do) your homework well.
10.  －What day _______(be) it today? － It’s Saturday.
（四） 一般现在时的各种句式变化
根据中文造句子。
（1）我是一位学生。
我不是一位学生。
你是一位学生？
（2） 她喜欢看电视。
她不喜欢看电视。
她喜欢看电视吗？
你发现了吗？以上两组句子中的主语和动词分别是？变为否定句和疑问句时它们发生了什么变化呢？
归纳：
（1）含有be 动词的一般现在时的句式：
v 主语 + be(am, is, are) + 其它
（肯定句）：I am from Shanghai.
（否定句）：I am not from Shanghai.
（一般疑问句）：Are you from Shanghai?
（肯定回答）：Yes, I am.
（否定回答）：No, I’m not.
有be动词，变疑问，Be提前，句末问号别忘记 。
变否定，更容易，be加not要牢记
Tips:当主语为第一人称时在一般疑问句中要改为第二人称you, 同理you也要改为I, we. 口诀： 一变二、二变一、三不变
（2）.实义动词的一般现在时句式：（有两种情况）
v 主语 + 动词原形 + 其它
（肯定句）：The pupils read Chinese every day.
（否定句）：The pupils don’t read Chinese every day.
（一般疑问句）：Do the pupils read Chinese every day?
（肯定回答）：Yes, they do.
（否定回答）：No, they don’t
v 主语(第三人称单数) + 动词三单式 + 其它
（肯定句）：He plays the guitar in the evening.
（否定句）：He doesn’t play the guitar in the evening.
（一般疑问句）：Does he play the guitar in the evening?
（肯定回答）：Yes, he does.
（否定回答）：No, he doesn’t
谓语为实义动词，变疑问，一二人称和复数do 提前，三单把does 来帮助，句末问号别忘记
变否定，也容易，do/does加not就OK！
