Grammar: I. The Simple Past Tense
一、定义与讲解
一般现在时表示现在的状态或主语具备的性格和能力，也可表示表示经常或习惯性的动作或一般性事实。 The sky is blue.
Mary’s father is an English teacher. I go to school at seven every day. She plays sports every day. The table has four legs.
There are 63 students in my class. The sun rises in the east every day. The earth goes around the sun. I like bananas.
We don’t like vegetables. He likes blue.
She doesn’t like strawberries.
二、注意：
只有主语在第三人称单数时在陈述句里面实义动词用“三单形式”， 其他人称（一，二，三复）用动词原形。 e.g. I/ We like English very much.
She/ He/His sister likes English very much. 那They呢 ? ★ 动词三单形式的变化规则：
1.（1）多数直接在动词词尾加-s.
play — plays like — likes ask---asks work---works get---gets call---calls （2）以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es. watch---watches wash---washes do---does go---goes
（3）以“辅音字母加 - y”结尾的动词，要先变y为i再加-es. try---tries study---studies cry---cries fly---flies 2.不规则变化：be---- is have----has
三．句式：一般现在时态肯定句式： 分为含有be动词和实义动词的两种情况： (1).含有be 动词的一般现在时的句式：
1.肯定句式：主语+be+表语( n./adj.等) e.g. ①He is a worker. ②You are nine. 含有be动词一般现在时态的句子转换：
（1）变一般疑问句：当句子中有be动词或情态动词时，则把be动词或情态动词(can,must等)提到句子的最前面，句末改问号。 一般疑问句句式：Be+主语+表语? e.g. ①He is a teacher. 他是个老师。
一般疑问句→ Is he a teacher? 他是个老师吗？
Yes, he is./No, he isn’t. 是的，他是。/不，他不是。
②I am eight .
一般疑问句→
I can play soccer. 我会踢足球。
一般疑问句→
（2）变否定句：在be动词或情态动词后面直接加not变成否定句. 否定句句式：主语+be+ not+表语： 例：① She is my sister.. 她是我的妹妹。
否定句→ She is not my sister. 她不是我的妹妹。
②I can play soccer. 否定句→
③The students and their teacher are here.
否定句→
★ 注意：对一般疑问句的回答： Is this a pencil?
Is that your backpack? Are these your parents? 2．当句子中没有be动词和情态动词，只含有实义动词时，句式如下： （1）肯定句： 主语（I/We/You/They/?）+实义动词(用正确形式)+其他 e.g. I know the girl. 我认识那个女孩。
They always ask the teacher questions. 他们总是问老师问题。
Lucy plays sports every day. 露西每天都要运动。 (2)一般疑问句：
变一般疑问句时，在主语前加助动词do或者does来变成一般疑问句； (注意：do后面用动词原形) e.g. ① I have two sisters and a brother.
一般疑问句→ Do you have two sisters and a brother.?
Yes, I do./ No, I don’t.
②The boys play soccer every day. 一般疑问句→
① He/Mike/ My brother likes black schoolbags.
→
② She/ Gina / Our English teacher goes to school by bus.
→
（3）否定句：
变否定句时，在主语后谓语动词前加助动词don’t或者doesn’t变成否定句，切记：助动词后的动词还原成动词原形。
e.g ①陈述句：We go to school at 7:00 every morning. 否定句→
陈述句：She has a brother. 她有个哥哥。 否定句→
※第三人称单数归纳总结如下：
